Many consumers that are hunting for an electric vehicle with lots of room opt for the 2021 Tesla Model Y. Why wouldn’t they when the automaker claims these models are “designed for safety?” However, there’s virtually nothing safe about the EV, thanks to the defects in the electrical system, service brakes, structure, visibility and suspension.

Problems with the Electrical System

As an EV, the electrical system needs to be top-notch for an enjoyable ride. Still, the Model Y continues to receive complaints about this vital system.

Here’s one complaint found on the NHTSA website. “The contact owned a 2021 Tesla Model Y. The contact stated that while driving approximately 70 mph but doesn’t recall; the vehicle began shifting from left to right for 5 – 10 seconds when another vehicle approached the passenger side of the contact’s vehicle. The contact attempted to disable the autopilot by depressing on the brake pedal and maneuvering the steering wheel however, the vehicle would not allow the contact to control it and it spun around and hit the median wall on the highway. Medical attention was received on the scene for the contact’s sister, who was a passenger. A police report was filed. The vehicle was towed to a Tesla repair center, where there’s an ongoing investigation. The manufacturer was made aware of the failure and informed the contact that they would respond within 6-8 weeks after the investigation. The failure mileage was approximately 300.”

Currently, the NHTSA is investigating Tesla because of electrical system problems. NHTSA Action Number PE21020 states that there have been eleven crashes identified by the Office of Defects Investigation (ODI) where Tesla owners needed first responders because of an electrical malfunction. This is simply inexcusable, especially if the company is priding itself on creating safe vehicles. Maybe Elon Musk should spend more time focusing on space exploration and less time on building vehicles.

Problems with the Brake System

Stopping the vehicle has been another issue entirely. The defects are leaving many people vulnerable with no warning.

Here’s an Edmunds review worth reading. “My wife’s Tesla Y had a malfunction this morning due to your regenerative braking system. She was driving out of a park from walking our dog going at 10 to 15 mph to a stop sign and all of a sudden the Tesla went out of control going so fast that she almost lost her life due to the cars malfunctioning. At the stop sign you can only go right or left only. You can see by the picture of the intersection coming from the park where the red post is, the car kept going straight until it hit a car and a light pole, after it hit the car. The thing is that my wife took the car into your service center at 901 Gilman to get her front windshield replaced. I’m not sure what they did there with the car’s computer while they disabled the car for service. When my wife picked up her car at the service center it was not working properly when my wife got the car. The side mirrors didn’t fold out so my wife flagged the service guy down to tell him why the side mirrors weren’t out when you put the car to drive. So that was odd. The service guy did something with the touch screen. Something from that point tells me that they did something to the cars computer when they serviced the car and didn’t tell my wife. Straight to the point that the car malfunctioning caused this accident. Your company is putting a dangerous product out on the street for people to drive is not right.”

The review goes on to say “I personally liked this car while driving it on the weekends with my wife and dog. I’m sure you know you are putting a dangerous car out on the road and that’s why there have been more accidents on the news about Tesla’s. Probably many more that don’t even make the news. The only had 1811 miles on it at the time of the accident. Still a brand new car that went berserk. What a damn shame. We should be compensated in some way. My wife and my dog got really lucky to be still alive right now.”

It turns out that there is also a brake-related recall dealing with the hardware. NHTSA Campaign Number 21V387000 states that affected models contain loose caliper bolts that could cause the caliper to separate and contact the rim, which would create a tire blow-out and possible accident. Whether the poor manufacturing processes or the electronic programming fail, the brakes are anything but reliable. Brakes aren’t often needed for space travel, which is why Tesla probably forgot to spend time designing these systems properly.

Problems with the Structure

The complaints over how the Tesla Model Y has been built also continue to roll in, with many customers expressing dissatisfaction over the quality control.

Here’s another Edmunds review. “That’s what it is… As a CAR it has not been designed correctly. The body it not rigid enough, the ride is harsh and noisy. Misaligned panels and gaps. Stupid glass roof is a heater in summer. Rear seats rattling with no possibility for repairs, been to service 7 (!!!) times, no solution… Service attitude is horrible, they just don’t give a damn.”

There’s yet another recall to pay attention to. NHTSA Campaign Number 21V389000 states that the front seat belts weren’t attached securely to the B-pillar. Without the right fastening, the seat belt might not protect anyone in an accident. Plus, NHTSA Campaign Number 21V388000 says that having fasteners not attached properly can also keep the retention system from working. Without the retraction function, occupants are left at risk. At this point, there’s really no reason to even have seat belts in the car; they don’t seem to be helping.

Problems with the Suspension

The ride of the Tesla Model Y doesn’t seem to be much better. Many customers continue to talk about drivability and suspension issues.

Here’s one from the Edmunds website. “After three trips to the service, still have steering issue and wheel vibration at highway speed.”

It shouldn’t surprise anyone that there’s another recall worth mentioning. NHTSA Campaign Number 21V835000 states that the front suspension lateral link fasteners could loosen, which allows the sub-frame to separate from the links. If there is a link separation, owners can count on a shift to the alignment, which would create instability and make it more probable that a crash could happen. A crashed Model Y isn’t a new sight, so people will probably not be surprised.

Problems with the Visibility

A final look at the visibility in the Model Y reveals even more problems, with both the driver window and auto-dimming glass.

Here’s a final Edmunds review to read. “We got our TESLA Model Y on a Friday last month and the very next day, we used the VENT feature, and our Driver window BUSTED!!!  3rd day our car was at the SERVICE CENTER.  Parts were of course not readily available.  Few days the car was returned (UBERed to pick up) and the next day the window function completely went out on the driver’s window.  Guess what, CAR was back at the service center.”

Tesla is fully aware of issues with the auto glass. Service Bulletin #SB-21-12-003 states that some models with auto-dimming glass cannot adjust properly when used at certain vertical angles. But, this is nothing new…Tesla has always kept drivers in the dark.

I own a 2021 tesla model y. I took possession of it on august 7, 2021, in santa barbara, ca. Ever since, I have had more than 1000 instances of automatic emergency braking (phantom braking) episodes while using cruise control or autopilot. ​the experiences of severe phantom braking have been terrifying. The car often slams on its brakes for no apparent reasons on all highways and freeways, mostly where no cars or obstacles are present. I worry about getting rear-ended, which could lead to injury or death. My tesla has been in for repair five times, and the technicians say they cannot fix it, that only a software update can solve the phantom braking problem they've been promising a software update since august 2021. After 16 months and five service appointments, I expect the problem would be solved by now. It hasn't. Please force tesla to remedy this very hazardous safety problem. Let me know what you are doing to force tesla to fix the problem.

On a long trip on I-70 across colorado and kansas I experienced 4 instances of "phantom" braking while using cruise control. I had set the speed at 78 and the car aggressively braked itself as if there was an object in the road when there was no object or reason to brake. In each instance if a car had been following closely they likely would have crashed into me. It also causes panic to the driver when the car aggressively brakes. I am contacting tesla service today to report this issue and hope that it will be addressed but there has not been any inspection at this point. There was no waring or issues with the car prior to this and it has never happened to me before. It only occurred when using cruise control as I do not have full self driving and was also not using lane assist.

I was driving about 65 mph on the highway with my tesla 2021 model “y” in “traffic-aware cruise control” (not auto pilot) when, for no apparent reason, the car decelerated rapidly. This happened four times during a 1 hour trip from boston to new hampshire. No accidents occurred due to this incident but it was very concerning. This is not a new problem but it is occurring more often since the software was updated to include “tesla vision” instead of radar. I did not report this to tesla because they are already aware of “phantom braking” issues with my model.

Heard loud clicking noises upfront when turning hard out of parking spot. Immediately I checked front wheels manually on looseness, but could not detect any movement. Decided to drive home (20miles). I was very careful not to steer to hard through curves. Upon turn into my driveway ( hard right turn which I took very slow) ,left front wheel suspension came unhooked and an approx 3” long x 1/2” galvanized bolt fell onto driveway. My 2020tesla model y was stuck at the bottom of driveway. My company mechanic came about an hour later ,jacked up the left side,removed front left wheel : the bolt as pictured below had loosened entirely from its nut and galled off releasing the wheel suspension and allowing the wheel to come loose . We temporarily fixed the bolt and drove the modely into our garage ( flat surface) 500 feet further uphill. Upon further inspection we found another bolt separated from its nut on the other side as well (4) other bolts totally loose almost entirely stripped from its counter nut. We found no sign of loctite or similar. The bolt in question is on bottom of lit up spot ( in below picture) bottom line: steering suspension bolts should not come loose on a vehicle not even 2 years old!

While the tesla vehicle attempts to turn off the brights when an oncoming vehicle approaches, the tesla vehicle fails to detect the oncoming vehicle and the brights remain on. This causes the oncoming vehicle to flash their brights back at the tesla vehicle because the driver of the oncoming vehicle is blinded by the brights of the tesla vehicle. I have asked tesla to fix this issue, but they refused to address it and provided a vague suggestion that a future software update will fix the issue.

I drove from flagstaff, az to las vegas, nv on 10/26/2022. I attempted to put my car in autopilot (adaptive cruise control) around a dozen times during this 260 mile trip. Every 10-25 miles the car would brake extremely hard forcing the passengers to lunge forward as if the brakes were being slammed. In every case, the car was in the same lane (no lane changes) with nothing but open road ahead. In most cases there wasn't a vehicle in front or to either side of me (only behind me). No corrective messages or indications appeared on the screen to explain this action. The only corrective action I could take was to hit the accelerator to avoid a rear end collision. When I contacted tesla about the issue, they checked the logs during this trip and found no faults in the system to explain this behavior.

I was returning home with my family at around 7 pm today (10/23/22). The autopilot (basic autopilot) was engaged and the vehicle was moving at 50 mph. Suddenly the car seemed to have engaged the brakes and I felt it almost came to a stop. At that time the red steering wheel alert appeared on the screen with the message to take control immediately. I had not braked nor there was a vehicle or any other object or vehicles in front of me or behind me. No vehicles were on the other lane either. The only thing I can clearly remember was a pickup truck waiting at a stop sign in a street connecting with the road I was on on the opposite side from me. Luckily there were no vehicles directly in front of me or behind me. It would have caused an accident if there was car behind me. All of us really got scared and my children are claiming they will never travel in my tesla again. The vehicle may be inspected if needed.

While travelling on tx-130 legally at 85 miles-per-hour with cruise control enabled, the braking system suddenly and without warning self-engaged, greatly reducing the speed of the vehicle. System available for inspection upon request (however I can help). The sudden speed change at such a high speed is alarming to the driver, possibly provoking unneeded corrective action which could destabilize the vehicle. If another vehicle had been following even reasonably closely, a collision was very likely. A collision at such high speed is obviously very dangerous. Manufacturer has not been contacted, but such "phantom braking" is the subject of frequent news articles from various sites. No explanation for the cause of the braking was displayed.

Based on other reports, this is common in other teslas. No warning alerts in car.

When on cruise control, the vehicle frequently brakes hard at highway speeds, jerking our bodies and forcing cars behind us to brake hard as well. Sometimes this happens when we're beside a semi truck or a car changes lanes far in front of us, but often there's nothing. There is no warning prior to the braking.

I started a drive from my house. I entered a destination into the nav system, it plotted a route. I then proceeded to start my drive. When I tried to backup, the backup cameras did not display any video, I waited over 1 minute and there was still no video. I then proceeded with my drive. The car would not start the cruise control, autopilot or fsd functions. Whenever I tried to engage the systems the car would state that they are unavailable. At this time, I also noticed that the nav system was not updating the display, it continued to display the same image that showed that I was at home in the driveway. After 15 minutes, I pulled into a parking lot to video the problem. First, I put the car in reverse and recorded that the cameras did not display video for over 30 seconds, I then started to drive and recorded that the navigation display was not updating. The display that usually has the lane markings and displays the other vehicles was also not working, there was no information other than a picture of my car with a totally blank gray area around it. I have contacted tesla about the problem, but they keep saying that they don't detect any problem with the car. I sent them the video and am waiting to hear back from them.

Vehicle was driving with auto steer enabled at 65 mph on freeway and braked unexpectedly and unnecessarily 3 times within a few minutes. Each time it occurred, I canceled auto steer and re-engaged. At no time were any obstructions or objects visible in front of the vehicle, and at no time did any warning lights or messages appear, the car simply braked without notice. Safety was at risk as cars behind me were traveling closely and were not expecting my car to brake suddenly, although I responded quickly enough to prevent further braking and accelerated out of danger. I have researched "phantom braking" and it seems this incident is exactly what was described in those reports. The car has not been inspected since the incident. I am hesitant to use auto steer since I do not trust that the cameras are adequately detecting what's in front of the vehicle.

5yjygdee2mf161659 vin 2021 tesla model y awd with basis cruise control this last weekend we drove from our home in arroyo grande ca to the mammoth lakes area. Enroute, we experienced a number of unneeded emergency braking events while on the highways at speed (65-72 mph). While this happened about a dozen time, 5-6 of them were significant slow downs and could have caused us to be rear ended. In none of these events was there any reason for the emergency braking. One happened when another car was approaching from the rear quickly to pass. These events led us to stop using the cruise control entirely for the last 2 hours of our trip home. I have not yet contacted tesla about this which I will be doing right after I submit this report. Prior to this, the adaptive cruise control had functioned normally with very few unexpected emergency braking events in the last year or so. We did disable the feature of “automatic emergency breaking” but that had no effect at all. This is a serious issue that need to be addressed immediately.

I have an ongoing problem with the dashcam recording, which for me is a safety issue. The dashcam constantly records from several cameras what is happening around the vehicle. The dashcam icon will show a red “x,” indicating that the dashcam is not working. Probably 80% of the time I get in the car, the red x is there. The solution involves opening the glove box and pulling the drive, waiting for up to 20 seconds, then replacing it. If that doesn't work, the usb drive needs to be formatted and all previous clips are lost, but probably 95% of the time the reformat fails. It was recommended by tesla service that I purchase another usb drive (?), but that did not solve the problem. I've had my car into tesla service for this issue or reported it through the app multiple times. For months, I've been told it will be addressed with a firmware update, but it has not happened. Other tesla owners are also having this issue, but it was addressed with a firmware update and the problem was fixed. The owners who have the full self driving beta have not had a firmware update to address the issue. We are the owners who paid -15,000 extra for the full self driving feature. I have not been able to get any information from tesla about an expected timeframe for this update. I ask, but I'm always told it will be a “future update.” I have asked if anyone is working on this issue, and they won't answer that question either. I would like to know the status. I've been very patient, but since there is aggression in the areas where I drive against ev drivers, and teslas in particular, I need this feature to be working. I have been harassed, had large pickup drivers tailgate or try to run me off the road, and I've been coal rolled. I've already used data from the dashcam to report aggressive drivers to the police.

Autopilot was on during a light rain event where I was traveling less than the posted speed limit on the i95 northbound highway. The autopilot appeared to force the car to abruptly jolt the steering wheel/tires, causing a slip/ hydroplane of the front end which forced the car into a left/sideways slide across the highway. The car slid sideways for about 100 feet or so before going straight into the concrete divider along the highway (front driver side initial impact, then rear driver side 2nd impact). Control could not be regained with the vehicle. Steering did not work (tried to correct the path), it felt as if brakes did not slow the vehicle as the car approached the divider. Autopilot was fully engaged and lane keeping was active… with at least one hand on the steering wheel and moderate level of attention to the road. I must say I had likely became over-reliant on the autopilot. No warning was provided to me as, prior to the incident. A similar hydroplane problem can also be seen on a youtube video posted online for the same model car. I experienced the same outcome as the other vehicle except I hit a divider after crossing lanes. I am however very pleased with how well the car handled the impact and how well the airbags went off, although also unfortunate- I do feel like the car may have been partially responsible for the accident itself. I have experienced a few prior occurrences where the car will jerk the wheel when in autopilot to keep or find a lane, even with hands on the wheel and full attention facing forward.

This cause a car to abruptly reduce the speed if not within the posted speed limit for that area. For example a car in autopilot or adaptive cruse going 70mph on the highway, the gps will start drifting into areas outside of you location and abruptly reduce the speed to assumed location.

These are instances of sudden deceleration of the car when no other vehicles or obstructions present while traveling on 4 lane highways at freeway speeds.

Rear end collision is the most of the highest risk when this sudden deceleration occurs. No warnings were given before the deceleration. These episodes are most noticeable when traveling at freeway speeds of 65+ mph in open terrain with no curves. One instance could be attributed to a shadow across the roadway, however, more times than not shadows across the roadway didn't cause ghost braking.

Possibly half the time the airbag is off, when it needs to be on. Two tesla service center visits were made. The first tesla service center visit reproduced the fault but did not correct it. The second tesla service center visit did not reproduce the fault and did nothing. The passenger airbag status off is displayed on the touchscreen. The faulty component(s) could be the seat occupancy sensor(s). This has been an issue since vehicle delivery. The vehicle is available for inspection upon request.

While using adaptive cruise control we have experienced multiple incidents of our vehicle braking hard, fast, without warning, and for no reason. The most recent incident just happened (07/21/2022) while driving on a 4 lane highway. My husband was using adp traveling at approx 65mph when suddenly our tesla model y began rapidly braking, throwing my upper body towards the dash and causing us to almost be rear ended by the vehicle traveling behind us. Thankfully, I did not hit the dash and the vehicle behind us was paying attention and swerved into another lane to avoid a collision.

The rear hatch can be opened while the car is in drive or reverse from a remote input from the app. On several occasion my hatch has opened from a remote input while in traffic while stopped at red lights. Tesla says this is normal behavior. So what is possible is someone can open the hatch from a remote input from anywhere without being able to see the car. My concern is when this has happened item could have fallen from my trunk into traffic resulting in damage or vehicles behind me. To close the hatch you must place the car in park first. Having a vehicle in park in traffic could result in a collision. You can not move the vehicle while the hatch is closing or it stops closing it takes several seconds to open or close the hatch and additional time to realize you must place the vehicle in park to close it. Remote input to operate the hatch should be disabled while the vehicle is in drive or reverse. The event has occurred on 4 occasions while driving the vehicle over the last year.

On july 16, 2022 I was traveling west on I-40, east of tucumcari, nm. I was using traffic adaptive cruise control (tacc). There were no cars within a mile of me, front or back. The weather was clear, the road was flat. The car suddenly braked without warning. The objects stored in the back of the car flew forward, striking the two front seats. The wheels did not lock up. I immediately stabbed the accelerator. I saw the power line bar graph indicator go fully to the right. I contacted tesla to request a service appointment. Tesla initially set an appointment but then cancelled it, explaining there was nothing wrong with the car. I was reminded that tacc (along with virtually all other tesla driving aids) is "beta" and may therefore not function as intended or expected. It was the responsibility of the driver to assume the risks implied. Prior to this event, I had already decided not to use any technology more advanced than the speed control (tacc) as they behaved poorly. I thought that adaptive cruise control (tesla: tacc) was a such a common technology that it wouldn't exhibit phantom braking. I was wrong.

The vehicle was on cruise control (not auto-pilot). Driving on freeway approximately 82 mph when the vehicle slowed to 60 mph instantly numerous time within my 160 mile drive. There were no vehicles in front or beside me. There were no obstacles in the roadway or on the side of the road. Sunny day with no clouds. There were no warnings lamps or messages that would indicate the car was going to brake. My safety was put at risk if there was another driver behind me, I could have been rear-ended. It could also had been very dangerous if there was adverse weather. Tesla was not able to recreate the problem and never found any problems with the vehicle. This was not the first time we took the vehicle in for phantom braking. Tesla blamed the driver. I was also told by a tesla representative the the vehicle can brake unexpectedly by sensing a shadow on the road from a cloud. Apparently there is no way to disable this feature. The vehicle has been deemed unsafe to drive by our senior management as this is not the first time this has occurred and tesla has not remedied the problem.

While adaptive cruise control was engaged on highway, it would disengage and harshly break even though there was nothing ahead as an obstacle. If there was a vehicle behind, it would have created a significant change of collision. During a 5+ hour drive, this occurred 20+ times. It seemed to occur when cresting small hills where visibility was somewhat limited ahead and when there were few cars ahead. In a few occurrences, there was a warning chime, but in other cases, it disengaged and braked silently. This just happened yesterday, so it has not been inspected by tesla.

They had us pull the usb in glovebox and see if anything is on there but there wasn't even though dash cam was activated.

Driving on major interstates across idaho, wyoming, and utah, there were several instances of so-called “phantom braking” — while using adaptive cruise control, with no other cars or obstacles in front, the brakes were rapidly applied, decelerating the car from roughly 75 mph down to around 60 before I could manually press the accelerator pedal to override the behavior. Not only is this dangerous for myself, but could easily cause an accident if people are following closely at highway speeds. If tesla's camera-only system (as opposed to radar) can't do the job, they should at least provide an option for a non-adaptive cruise toggle that would hopefully work around the issue.

This is a huge safety issue when the screen goes blank when driving. Tesla says there's nothing wrong, or try a reset, or the next update will solve it.

We just completed a 6500 mile round trip road trip from so cal to toronto canada and back. 5/24/22-6/12/22 during the trip we used the "auto pilot" with and with out "auto steering" not full self driving. I lost count of how many times we encountered "phantom braking" with the car at highway speeds. My guess would be at least 50 times. It got to the point where I would not use auto pilot especially when there was heavy traffic at full highway speeds. My deduction on why this is happening is that the tesla cameras are "infrared" sensitive and it seemed that the car was applying the brakes when it would see the heat waves off the hot road surface. Also in early morning one day the sun was directly behind us and the cars shadow was directly in front of us on the road surface and it kept applying the brakes thinking it was another car. In slow moving bumper to bumper traffic going 30mph or less does not seem to initiate the "phantom braking". But at highway speeds it is super scary and dangerous when this happens. ;(

Description
There are 4 issues to report for our tesla model y: 1) on the highway, our tesla often presses on the brakes and slows down by itself when it should not be doing so. This occurs when we have adaptive cruise control on. We've noticed that at the time of the slowdown, the tesla misreads the highway speed limit. For example, the tesla will read the speed limit as 70 mph, then all of sudden without warning, the tesla will suddenly read the speed limit at 40 mph, which then causes the tesla to break and slow down by itself, when the speed limit is actually still 70 mph. This can happen several times on a single highway trip. Aside from the shock we receive as a driver as our vehicle slows unexpectedly, this could cause a rear end collision if a car is following us too closely from behind. 2) when we use adaptive cruise control and the steering assist feature, the car does not recognize to slow down on highway off ramp curves. I monitor the speed around curves, though if a driver is not aware of the issue and expects for the tesla to take the curve slowly, this could cause an issue. In particular, if there is a big curve, I'd be concerned of the tesla losing control and going off the road, due to speed. 3) the car will often provide a frontal collision warning, even if there is no car or object in front of the car, while it's in motion. This can lead to confusion for the driver or possibly hard breaking, which could cause a rear-end collision, if a car is following too close behind the tesla. Also, the tesla driver may swerve unnecessarily to avoid an object that isn't there, which could cause a collision. 4) the tesla is advertised as being able to travel over 300 miles on a single charge, however, the conditions for this to happen seem incredibly difficult to meet, as mileage is usually far less than this. This can cause drivers to overestimate how far they can drive, which could lead to cars urgently pulling of the road to prevent stalling where traffic is.

Several instances of emergency braking applied without warning or obvious need during multiple driving sessions. This results in an unexpected rapid vehicle deceleration. Fortunately no other vehicle was following close enough to represent an imminent safety hazard though it is easily plausible this could happen. Typically the issue occurs when traveling uphill or around a bend and encountering traffic in an oncoming lane, structures (bridges) or dark shadows. The unexpected emergency braking has also happened when adaptive cruise control or autopilot is engaged while overtaking large vehicles on the left (tractor trailers in the right lane). I have also noticed several erroneous lane departure warnings despite turning off these notifications on the dashboard. They are more a nuisance than safety hazard so far but would like to completely silence them entirely. These issues have yet to be reproduced or inspected by the dealer, police, insurance or other investigator. No warning lamps or indicators were active at the time the braking or lane departure warnings were observed.

On one occasion while passing a semi truck with car on my tail came within a foot or so of being rear ended. Many other occasions where got to point I do not feel safe using the cruise control. We have driven it from denver to tucson in november and back in may, both times was worse on wide open western roads, sometimes tho not always with bright sun, pretty unpredictable and random but often to point of not using any of our autopilot or cruise control functions with confidence of safety. No warnings, lights or prehappening signs. Reported and examined in tucson on arrival there in nov/21. Told would “get better with time” and further hardware updates. Hasn't happened with city driving (tho rarely use cruise control.

After the crash, I confirmed that all safety features were enabled and I have always installed all regularly scheduled updates. After searching online forums, I found many customers reporting problems with their on-screen camera not activating. I have noticed that the camera did not consistently activate in the past. Sometimes it would, other times I would have to manually press the camera button on-screen in order to view behind me. There were no on-screen notifications of problems before the event. However, there was one notable change I made to re-enable sentry mode (security) after being disabled for some time. Prior to the event, I was notified that two sentry camera events were available to watch but they would not load when I touched on screen. After the crash, I discovered after the crash that both sentry and dash cam were not working so there was no footage at all of the crash! Nor were these sentry events visible. This leads me to believe there is a bug with the camera system.

I am reading about the tesla braking for no reason & wanted to report my own experiences with this. I have not reported this before to anyone at tesla, just told my husband. Numerous times (at least 5) over the past year I have owned my y it has suddenly braked for no reason. It either always or almost always happened when I was going freeway speeds on a turn & there was a vehicle in the lane next to me that I think my tesla thought I was going to hit. But I wasn't. It was a sudden brake that if I had not been in full control of the car with my feet ready to move so I had to hit the accelerator pedal quickly there could have been a big problem if there was a car behind me. This issue made me stop using the auto pilot on the highway it happened the most on - hwy 80 between sacramento & truckee ca. But it has happened on other freeways too. It makes me very hesitant to use the autopilot unless I am on a straight freeway.

While using the autopilot (not full self driving feature) on the highway, I have experienced multiple inatances sudden braking for no reason. No vehicle has been in front of me in these instances and it has occurred most often on undivided highways and highways where there is a hill. This has made engaging the autopilot dangerous as there are cars behind me and I could have been rear-ended on multiple occasions. Additionally, while driving manually on city streets where there are stop signs, there have been multiple instances where the vehicle has given me a forward collision warning because I am slowing down to a vehicle that is ahead of me at the stop sign. This has most often happened on uphill and downhill instances where there are stop signs.

My model y tesla, while driving on the freeway using full self driving, would abruptly slow down from 70mph to 40 mph in matter of seconds without warning and luckily there was nobody around me. I did a bug report on it many times but tesla discounted that. Also my front windshield wipers would come on for no reason even on a sunny day. Sometime on a raining day when going into a tunnel the windshield wipers would stop and would not come back on when I get out of the tunnel and that is really scarily as I was unable to see during heavy rain. I had to manually turn it on and that took a few seconds and in the meantime I could not see anything due to heavy rain. I brought this to tesla and they told me that the windshield wiper control and the headlight use the same sensor and there is nothing I can do except to place the windshield wiper on manual mode. The rain detection wipers are on many different model cars without issues. I am not sure why tesla could not add an additional sensor just for the windshield wipers.

Description
On multiple occasions, I have experienced the "phantom breaking" problem when using either adaptive cruise control or the limited self driving feature on my tesla. I've experienced the problem when driving in traffic (me in another lane, passing a larger vehicle) when the breaking system will activate and all kinds of warning sounds given by the vehicle. I've also experienced the problem when driving alone on the highway (no traffic in either direction), usually in daylight conditions, when the breaking system activates and alarms go off. Additionally, I've experienced the problem when cruise control is activated and a vehicle turns in front of me (either in the same direction or sometimes when turning on a cross street), it's just strange for this to happen when the vehicle is about 1/4th of a mile (or more) in front of me and the turning action of the other vehicle will be complete without causing any concern for my vehicle. This has happened 30-50 times since I purchased the vehicle in late september 2021, so I don't have specific dates for each of these occurrences but it happens so frequently that I pretty much don't use the cruise control or self driving function anymore.

On sept 2 or 3, 2021, I was using cruise control on long straight highway, with no other vehicles in sight, sunny clear weather, traveling at 65-70 mph. Suddenly brakes slammed on very hard. A short time later, same conditions, brakes slammed very hard 4-5 times in a row, rapidly. It was terrifying. I stopped driving for the day and I have never dared to use cruise control again. When I returned home I took the car to the dealer and told them time and location of incident. I assumed there was something wrong that would be corrected, like a camera not pointing correctly. The tesla employee checked the computer record of the incident, told me there was nothing wrong and changed the subject. This was an extremely scary thing for me, severe enough that I got a sore neck, and I have no doubt if another vehicle was following I could have been rear ended. I actually was relieved to read about other tesla owners experiencing this, and thought there would quickly be a solution. I am disappointed there has not been. I have been driving for over 50 years, have never had an accident while driving…. I am very cautious! I want to emphasize again, this was not a minor incident. It was very very frightening, and very dangerous.

Due to the nhtsa demanding the removal of the boombox feature while driving I have had several issues which were previously avoidable. The vehicle does not make a sound when driving and often times pedestrians cannot hear the vehicle. The horn without custom sounds is aggressive and could incite road rage from pedestrians or other vehicles when previously being able to play music via the outside speakers via boombox alerted pedestrians and in extreme cases a funny sound accompanied with the horn would cause the pedestrian or other vehicles to notice but not incite road rage. I am imploring nhtsa to allow tesla to bring back the boombox while driving and the custom horn sounds before more people get hurt! This is an nhtsa demand issue and not a tesla issue. This is a daily issue when driving in parking lots or through neighborhoods!! Nhtsa's original demand being that the pws was not able to be audibly heard while boombox was engaged is garbage, boombox enabled an audible warning to pedestrians in conjunction with the pws. Now with the lack of boombox while in drive or custom horn sounds there are many instances personally witnessed, told to me, and experienced where road rage has occurred and pedestrians are in the roadway unaware of a vehicle approaching. I propose the solution of returning to allow custom horn sounds and boombox while driving but when in reverse to mute the boombox and allow the pws to be heard loudly. This will appease all sides and allow pedestrians a warning signal that the vehicle is in reverse while also not inciting road rage from a gentle or funny custom horn and alerting pedestrians and other vehicles a moving vehicle is nearby when in drive. Again, I implore you to make the right decision and allow tesla to enable custom horns and boombox while driving to save lives!!

My son was driving my model y performance trim tesla model y on may 23,, 2022 and thank god he was in a relatively safe parking lot; the vehicle had a loud thud noise coming from the rear and then it spontaneously died due to allegedly a rear motor failure (it's a dual motor model y). The tesla then turned off essentially and locked itself in "park" -- the vehicle could not be taken out of park. Had to get it on a flatbed -- it now sits at the san antonio, texas service center off interstate 10 where allegedly it will be undergoing a diagnosis. But this rear motor failure (according to some of the indicator lights) is unbelievably dangerous inasmuch as the failure occurred without warning and without an opportunity to apply reasonable contingency protocols -- had this happened on a highway or street lane -- the complete unexpected stopping of the vehicle would assuredly be cause for grave damage and serious bodily injury or death.

Unspecific event. I hope this report, without my having an incident myself is looked into enough to apply a standard across all manufacturers to make sure the public aren't so unknowingly put at risk. All because of an ill thought through design. My vehicle has no easy access to exit rear seats if there is any kind of electrical failure. My rear passengers will not be able to exit the vehicle. Manual override of electronic door controls are hidden beneath door panels and trims. With no mechanical connection on the outer handle, even if the driver uses the front manual release, they cannot rescue rear passengers. The outside door handles are electronic only. Imagine a fire like vancouver happening, when a child is in a car seat or has less mobile passengers like seniors. Neither can be expected to climb to the front or out a side window to reach safety. No means to unlock doors or open doors makes this vehicle unsafe to carry passengers in the back, nevermind versions of my vehicle that have 7 seats and a third row, which will most certainly be carrying kids due to the available room. . This design flaw exists in tesla model 3's also. I'm not sure of other vehicles or brands. Older vehicles with mechanical door controls still allow a door to be opened from outside if on fire or suffering an electrical problem. These back seats aren't safe and for model y as an suv marketed to families, it's only a matter of time til tragedy occurs.

Driving south on interstate 89 in vermont, approaching exit 2. Auto-pilot and auto-steer engaged. (note: this vehicle does not have the optional "full self-driving beta" mode.) in the right lane, road curving to the left. The right-hand exit ramp appeared almost directly ahead. Auto-steer tried to continue straight ahead into the (low-speed) exit ramp at full highway speed. I had to physically wrestle the auto-steer for a short period, which forces it to disengage, to keep in my lane on the highway. Daylight, clear weather. Had I not had my hands on the wheel and had I not paid attention, the car would have taken the sharply curving exit ramp and I would have run off the road into trees. This is a failure of the auto-steer software. I have also had issues with auto-steer when driving past on-ramps and off-ramps that do not have dashed lines that continue the right-hand edge of the driving lane. In these cases, the auto-steer attempts to abruptly correct into the middle of the suddenly wider "lane" as indicated by the edges of the ramps and the left side dashed line. It should maintain its standard distance from the left lane markings instead of trying to center itself in the suddenly wider perceived lane. I have the auto-steer lane correction enabled and set to "early" mode (which is the most aggressive setting). This is a software bug, not a component failure.

Description
Occasionally, while the adaptive cruise control (tacc) is engaged, the vehicle will suddenly brake as if there is an obstacle immediately in front of the car, even though there is not one and the road is completely clear. Sometimes this happens randomly on a divided highway, other times it happens on a two-lane highway when a large truck is approaching in the oncoming lane. Sometimes it is a minor deceleration, other times it is aggressive braking. During one particular road trip, on an empty & divided highway, the vehicle braked unnecessarily over 20 times in a 1 hour span. This is an ongoing issue and continues to occur any time tacc is engaged and there is a clear, unobstructed road ahead of the vehicle. This prevents a safety hazard to any vehicle(s) following behind, as well as the occupants of the offending vehicle, because it could directly result in being rear-ended. When I initially reported this problem to tesla in december of 2021, they refused to acknowledge it, much less attempt to address it. I submitted a second request for service that same month, 3 weeks later, and their response was the same. However, when I submitted a third request this month (april 2022), the dealer finally confirmed that this is indeed an issue. Yes, the vehicle has been inspected by the manufacturer.

Description
When driving the vehicle primarily on highways and with the adaptive cruise control active, the car randomly reduces the cruise speed by up to 35 mph and then proceeds to slam the brakes. This happens intermittently on open road, 4 lane highways, with and without any traffic nearby. We logged the times that these occurred and took them to our local tesla service center and they said “this is a software bug that we have to wait for tesla to fix. There is no way to disable the adaptive nature of the cruise control either.” we informed them that this has been occurring for about 6 months now and they said “you'll just have to wait until tesla fixes the code. It gets better every release so eventually it won't do this anymore”

Description
All of these incidents occurred with adaptive cruise control engaged, and sometimes with lane keeping engaged. The vehicle frequently brakes, or slows dramatically, when on the freeway and there is no obstacle in the vicinity. Over the last three days I made the drive from burbank to anaheim along I-5. Always in the same area, the car would suddenly slow. In two out of the three incidents, the "max speed," which was set to 80, dropped to 45. Simultaneously, the car thought it was in a 55 mph zone (it was a 65 mph zone). In one of the three instances, the max speed was not changed, but the car still slowed dramatically. On the same commute, the car navigation always has me get off on artesia blvd, and then get right back on the freeway. The adaptive cruise has a configurable follow distance that the car seems to generally ignore. It's a number from 2 to 6 or so, and it's not clear what it's supposed to be (seconds or car lengths). It's rarely either, although it should represent seconds. When traffic comes to a complete stop, the car waits until it is too close to brake. When traffic begins moving, the car waits too long to start moving, and then accelerates excessively to catch up. Finally, when using the regular adpative cruise and lane keeping, I would signal lane changes and initiate the change. The car disengages steering but maintains cruise. In many cases, while still indicating the lane change, the car's lane departure warning will sound and it will attempt to correct my steering, which I have to physically override. My nissan leaf had adaptive cruise control, lane centering, and lane departure avoidance, and it never gave me these issues. Oh also, the tesla frequently and erroneously warns of forward collision. It's really terrible, and it's due in no small part to the removal of the forward radar sensor.

Over the course of an eight hour drive on a single lane highway, the vehicle abruptly applied brakes without any warning at full speed multiple (at least 30 times). In some instances, there were vehicles in the opposite lane. In other instances, there were none. In all cases, there were no vehicles in front in the same lane. Weather conditions were clear and dry, with full daylight illumination. This issue is most likely related to the camera-only change made to tesla vehicles, which are used for tacc and autopilot features.

Frequent abrupt and unsafe phantom braking while using cruise control. Mostly due to headlights from semi-trucks coming in opposite direction but occasionally from just a dark patch on the road. On a long road trip from wa to az, it made using the speed control feature impossible. The vehicle would lurch hard enough to physically throw you forward in your seat and rapidly slow the car (increasing potential to be rear ended). No warning messages or failure notifications. The problem was reported to tesla (not to police, insurance, etc because no accident ensued) and the response was in a nutshell “it is working how it should “.

Description
When tesla infotainment system needs a restart due to malfunction (which is easy to accomplish by holding the 2 steering wheel buttons for 10 seconds), the car doesn't allow the turning signals to function. All other essential motor functions work normally, it's just the turning signals don't. As a result, there were a couple of times when I needed to restart the screen due to bugs and turn on my signals without success - since I had to turn in a high traffic street. It's great that the car allows the infotainment to be restarted, but I don't believe a safety function such as turning signals should be impacted - there should be a temporary way to keep them working to avoid this safety hazard. I love my car and love what the company is doing, but this one I had to report since I'm concerned this might impact a lot of other drivers and potentially cause injury.

While driving along on an interstate highway at night, the frame rate for the display system including speedometer and other vehicle information drastically dropped. This resulted in limited situational awareness of what the car was doing. Updates for lane changing, blind spot detection, and lane departure warnings were delayed/lagged as a result of the reduced frame rate. This did not impact how the vehicle drove, or activation of turn signals, and the lower frame rate did not result in any flickering of the display. A display reset was required while driving at highway speeds to regain full situational awareness.

Description
We have had issues with the “autopilot” function braking when no obstruction exists. Situations that trigger these unnecessary breaking events generally involve shadows on the roadway, visible disturbances such as reflected sunlight, or other visual circumstances that in some way impact the appearance on the roadway surface. These appearances are generally widespread on county roads and state highways, but are less frequent on the interstate highways. Due to the severity of these breaking actions we have greatly reduced the use of the “autopilot” feature, and now only us it sparingly on the interstate when the lighting conditions are good. Due to loss of confidence we use it very infrequently, only once every few weeks at most. These emergency breaking events are greatly unwarranted 95% of the time. In addition, we feel that the unexpected nature of these events and the severity of them have increased our risk of collision. This is due to the unexpected and unintended breaking causing an accident from a vehicle rear ending us on the highway. We have not been in a collision yet. I feel that this feature is not yet ready for release and it should be disabled or rolled back until such a time it can be trusted to not increase the risk of collision for the occupants. To answer the questions specifically: what component or system failed or malfunctioned: autopilot / automatic emergency breaking. How was your safety or the safety of others put at risk?: uncommanded and unwarranted emergency breaking increases risk for an accident. Has the problem been reproduced or confirmed by a dealer or independent service center?: no has the vehicle or component been inspected by the manufacturer or others: remote diagnostics performed by manufacture. No problem found. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear?: other then alerting to the breaking action, no warnings have been displayed.

While driving on the highway from ohio to arizona in december and returning to ohio in february when using the adaptive cruise control, my car would suddenly and without warning brake and felt as if it would stop if I had not pushed the accelerator. I drove a total of 10 days, and it happened on some days two or three times, once happening five times. Luckily when it happened the traffic was light, but if someone had been behind me, I'm sure there would have been a rear end collision. It caused my wife and me to lurch forward from the sudden deceleration, and our seatbelts kept us from hitting our heads. When I got home, I reported it to tesla by phone and was told that someone would get back to me. On march 24 I received an email, stating that "this behavior is a known limitation" and "traffic-aware cruise control may react to vehicles or objects that either do not exist or are not in the lane of travel, causing model y to slow down unnecessarily or inappropriately." tesla did not offer to remedy the problem, saying only that "the braking behavior will improve over time with software updates." tesla suggested that somehow I did something wrong, when it stated: "when using autopilot features it is the driver's responsibility to remain aware and be ready to take corrective action at all times." there was no corrective action to take except for the sudden braking of the car.

Phantom breaking while using adaptive cruise control. Happened 3 times in past two months. First two times were traveling on a major highway, both on a hilly section at the bottom of a hill, with no other cars nearby. The car apparently thought the hill was something that should cause the breaks to engage. Car went from about 70 to 55 in a few seconds. Very startling. The third time was on a residential road, going about 38-40. There were no cars nearby, and the breaks engaged abruptly. The safety implications are obvious, although luckily there were no cars behind us when the breaks went on. We reported these incidents to tesla today and asked for a service appointment. A tesla representative called us and said we had assumed these risks when we bought a tesla, there was nothing they could do, and it was probably driver error. They did agree to make an “internal report.” we told them we would report this to you. This is our second tesla. We had a 2018 model 3 and never had any problem like this. We wanted more storage space and higher seating, so we sold the 3 and bought the y in july 2021, not understanding that tesla had changed to an “all camera,” no radar/lidar safety system. Add us to the growing list of evidence that the new system is dangerously faulty.

The sun was on my left (east) and there was a truck approaching on the opposite lane. When the truck passed (I guess it cast a huge shadow as it blocked the sun on my left) the car slammed on the brakes. There was no warning.

My car sometimes brakes for no reason. On many occasions there are no cars anywhere near me, but the car breaks suddenly.

Hello, we have had our car for almost a year now. Ever since we purchased the car we have been having an issue with the "phantom braking". On writing about it to tesla within a few months after the car purchase, they sent a representative to our house with whom we went for a test drive. On the test drive, while on the highway with the vehicle on auto-pilot the car suddenly slowed down fast, similar to "slamming the brake", for no reason. There was absolutely no obstruction in front of us. The representative mentioned that he had heard of this phantom braking but this was the first time he really saw it and he would pass the info to tesla. We later got a reply from the company which explained that "as more info is gathered by tesla from your experience as wells from other owners, the system will improve and issues such as yours should decrease." we still consistently get this problem on almost every trip on the highway and if the auto-pilot is engaged. In fact it does happen multiple times on each trip! We sincerely feel that it is very unsafe esp. For a software which is supposed to make driving safer.

While driving from tucson to denver the vehicle suddenly decelerated and/or braked no less than hundreds of times with varying rates--sometimes just a couple miles per hour and other times more than 30 miles per hour. These events were generally on a divided interstate highway with clear visibility, flat, straight roads without precipitation and oftentimes without another vehicle within 1/2 mile or more. These events even happened 3 times within 3-4 minutes while I was speaking to tesla roadside service trying to disable all sensors/interventions. More than once there was a vehicle behind me at highway speeds that thought I was "brake-checking" them and would anger them and cause them to honk and give me a few finger symbols (road rage)... There was no reason for the car to suddenly brake; no cars merging or in front of me other than light vehicle traffic in the opposite direction of the divided interstate. I asked several times if there is a way to turn off all the "assistance" (unsafe interference) and just have it function as a normal cruise control without "traffic aware" and other automatic braking features--but the answer was no. I am not exaggerating when I say this happened hundreds of time during my trips. I always turned off the speed control when the roads were curving because I knew that it would suddenly brake during a mountain pass curve and upset the vehicle--make it difficult to control, and potentially cause an accident at high speed for no reason. My risk tolerance is fairly high, I have been driving cars with "eyesight" and radar speed control and advanced safety features for over 10 years and have never felt less trusting or less safe than I do now in my tesla model y. I think tesla should disable the "safety" feature until they can resolve the issue--I believe it will cause accidents even when someone is fully aware of its sudden, random braking issues.

This complaint is specific to the automatic control of the model y related to "phantom braking". This is an ongoing problem with the "autopilot" and "full self driving" functions on my car, it has always had. Most of the miles on my car are freeway and highway miles. Regardless of which of the automatic functions selected on my car, "phantom braking" occurs repeatedly in a startling fashion that doesn't seem to be related to the environment the car is being driven in. The problem is consistent enough that I will not use any of the auto driving functions when I have passengers in the car with me. The problem requires constant intervention by the driver. There are 2 versions of this type of un-commanded breaking: 1. Unexpected braking with no computer warnings or alerts. It can be hard braking or, light to medium breaking, for no apparent or justifiable reason. This type of breaking can happen sporadically or, at times it can happen in a chain fashion that can be so continuous that it becomes necessary to disengage the automatic functions completely. Although, it happens at varying times of day and different kinds of traffic, making it nearly impossible to relate the event to any specific cause, I have noticed it happens almost 100% of the time when a large vehicle is approaching from the opposite direction on a two lane road. That will usually be version 2 type of full emergency braking. 2. Full emergency braking with computer visual warning and loud computer audio alert. This type of braking is extremely dangerous because, just like with version 1 braking, it happens un-expectantly and for no apparent or justifiable reason. If this type of braking happens in freeway traffic, as I have experienced, it can cause a rear end collision or worse, a chain of collisions. Tesla is aware of this problem and I have reported it multiple times. I have received no response from tesla related to these problems. I have experienced this problem since the car was new.

While traveling on us 93 southbound, the vehicle raandomly saw oncoming traffic as a threat and applied braking. This was most pronounced seemingly with large trucks, usually white in color, and occasionally apparently with flashing lighted signs. This phonenomen has occured at other times. Often in city traffic on city streets, it is overly sensitive and applies braking when cross-traffic occurs but is not yet a threat. I have not yet been rear-ended but have decided to only use this feature when I can be reasonably sure no one will be close behind me. Tesla's response is that this is a beta feature. Your safety rating included this "feature" as one of the positive factors. Maybe that was a mistake?

The incident occurred after a rainstorm and there was some debris laid out across the road. We were travelling in the morning before sunrise at 20 mph and we felt a small branch or object hit the underside of our car. We took it out to drive again at noon time and it warned us that the coolant was low and that car may not start up once shut down. We towed it to tesla service center in paramus nj and they informed us of the condition. They informed us that the coolant pipe was punctured and the coolant spread onto the battery. They explained to us that the branch hit an area and caused the coolant to leak inside the battery and there is no plate to protect it at the underside of the car. They also informed us that there could have been a fire accident if we put it on charge after the underside collision. They also informed us that the coolant pipe was plastic. Despite this flaw in their design, they insist that they will not cover it since it was an external issue and have asked us to pay close to ,000. Please help

This report is not about a single incident, but rather a repeated problem over several years with the adaptive cruise control on 3 different tesla cars I have owned. These cars are a 2017 tesla s, and 2 different 2021 tesla y models. In each case, whenever these cars are driven on a highway with the adaptive cruise control engaged, several times during each hour of driving, the cars will rapidly brake/decelerate with no action taken to cause the situation by the driver, nor any external situations with the traffic that would justify them. With the tesla regenerative braking, these deceleration events are so extreme that it would be easy to imagine an accident with a car following closely behind. Indeed, with these situations occurring with no warning and extreme braking they are quite frightening to the passengers traveling in the car. During the most recent occurrence, I noted the exact day and minute of it's occurrence, and filed a service request with the local tesla office. Even with the exact time of this event, the service center was unable to find anything wrong with the car. The tesla service center attributed this issue to problems with the autopilot and full self driving software, but none of my cars have had this optional software-only the software which came standard on each of these cars. While otherwise appreciating the good characteristics of these cars, this unexplainable deceleration problem is what caused me to sell the prior 2 models before purchasing this latest model y, hoping that this problem would not recur. It is worth noting that I have owned several other make and model cars with comparable adaptive cruise control, yet this situation never occurred even once on any of these other makes of car.

While using autopilot, the vehicle brakes when coming over the crest of any hill on the highway. It's not even occasionally, it's every single time I have autopilot/cruisecontrol enabled, it phantom brakes. To be clear, this is with just autopilot, not fsd. My guess is the car can not see the road on the other side of the hill, so it freaks out. Also, this is a case of the car braking, it does not disengage autopilot. After this happened about 20 times on a road trip I have just stopped using it. It's terrible. Also, another detail is this happens whether it's just on cruise control or autopilot. Even if I am in full control of the steering of the vehicle it still happens. Tesla doesn't have an option to just maintain speed with the cruise control where I control braking, it's the adaptive cruise control or autopilot. Very frustrating to not be able to use something as basic as cruise control when driving across the vast expanse of west texas without having my kids jostled awake at the crest of every hill (big or small).

CategoryLane Departure: Blind Spot Detection
DateFeb 27, 2022
StateTX
Description
The blind spot warning creates a visual indication on the media control unit display in the center of the dashboard, but no aural warning or indication when looking at the side mirror. In effect, this requires the driver to look forward and towards the center of the vehicle to gain any value of warning, directly opposite the threat of a vehicle in the left side blind spot. This issue manifested itself while I was driving my vehicle on a 6-lane divided arterial road and was attempting to change lanes towards a left turn lane. I observed a vehicle approaching on my left while I had my turn signal activated (and saw the vehicle indicated on the mcu), and once the vehicle had passed I began to move towards the left lane to find a second vehicle rapidly approaching and pass that I had not previously seen. An aural indication that the vehicle detected another passing vehicle would have alerted me before I began changing lanes and had to perform an abrupt evasive maneuver to avoid a collision. This issue has been raised with tesla numerous times based on comments in various online forums but has not yet been addressed by the company.

This vehicle when on adas (aka autopilot) and adaptive cruise control I experience constant "phantom" braking where car will slow down or slam on brakes for seemingly no reason. Most noticeable on a non separated highway phantom braking occurs constantly and is very predictable when large truck is near on the oncoming lane; happens probably 80% of the time. Slamming on the brakes for no reason is alarming and dangerous in my estimation. This system is completely unusable and very unnerving. Ironically I had a 2019 model 3 with the same features and did this very rarely so this feature is much worse than it was on older vehicles with radar.

I was driving on a 2 lane highway at about 60 mph in the middle of my lane. The adaptive cruise control was used to manage my speed. Another vehicle was travelling in the opposite direction going toward me, and in the middle of their lane. The other vehicle was an 18 wheel truck. Suddenly, with no warning, the braking system slowed my vehicle. Both myself and my wife felt our seat belts tighten quickly. There was a vehicle behind us, that nearly hit us when the brakes were applied so quickly, for no apparent reason. I had to quickly put my foot on the accelerator pedal to stop the braking, and get back to the correct speed. This has happened several times, usually when driving on a road that gently curves to the right. The sudden braking also occurred when there was no other traffic, just a new section of pavement on the road ahead of us. The loud collision warning sounds came on each time, which startled us. There was no reason for the warning. This caused me to react very quickly, which could have resulted in overcorrection, possibly leading to an accident. After learning about bug reports, I sent in a bug report to tesla immediately after every incidents I called tesla to report the problem. They eventually replied that there were no issues with my vehicle, that it was working properly. I set up a service appointment to have the problem diagnosed. I wanted them to diagnose the "phantom breaking". Their diagnosis - "verified proper operation". They noted that it was a "known characteristic, future firmware solution". The correction was "remote education" - they tried to inform me how to correctly drive with adaptive cruise control, then told us to stop using cruise control. My wife and I are scared of using cruise control, as we are sure it will happen again, and someone could crash into us from the rear if it happens again. The way tesla responded made us feel as if they didn't care about our concerns.

This is the second tesla I have owned and the previous model did not have this problem at all. This vehicle has phantom emergency braking occurrences during use with the cruise control and also with the auto drive feature. It will randomly brake hard when there is nothing around the vehicle, either in front, back or sides. I have contacted tesla 3 times, the first two they said nothing was wrong and the 3rd time is scheduled for february 28 here in houston. The first two times tesla told me to record the time and place of the occurrence so that they could look at the data that was being input to the vehicle. I did this but it did not work. When the vehicle has an emergency braking occurrence all of the occupants of the vehicle are violently slammed forward until the driver can push down on the accelerator or disable the cruise or auto drive. This has caused us to almost lose control multiple times. As of right now no one can use the cruise or the auto drive feature at all, it is just too scary when the vehicle decides to have a phantom brake event with no problems around the vehicle. This has occured dozens of times over the last few months.

At 12:21pm on february 20, 2022, while driving on a divided highway (us-36), the tesla model y braked hard with no cars nearby. The braking occurred as the car encountered a shadow on the roadway from an overpass. The sun was very bright, so the shadow had very high contrast. We suspect this is a case of "phantom braking", as has been reported with many tesla model y and 3. The problem is not easily re-producible, but we also do not feel safe using the cruise control feature any longer, so it's unlikely to be reproduced soon. The vehicle has not been inspected by tesla, nor confirmed by the dealer.

The "hard" braking occurs without warning and rapidly reduces speed by about 20 mph, which is extremely dangerous especially with traffic from behind when traveling the posted speed limit of 65 mph. The majority of observed phantom braking events will reduce speed from 5 to 20 mph. Phantom braking has occurred the entire time we have owned the vehicle (8/21)

While adaptive cruise control is enabled, the car will hard brake at random. The screen doesn't indicate why the car is randomly braking, not are there any other indicators as why or when this will happen. This occurs most often while going around corners, up hills, or when traffic is oncoming in the other lane. This happens on standard roads and highways - although highways are a little better as long as the opposite bound lane is separated by a wide median. Contacted tesla support december 16, 2021 in which their reply was that "the car is learning... Apply constant pressure to pedal in order to override braking system". I did try that for a couple of months, and instead of hard braking, it is a little gentler, but then I run the risk of going over the speed limit as constant pressure has to be applied ontop of whatever the cruise control is set to. Not too mention this defeats the purpose of having cruise control.

Multiple occurrences of unanticipated hard breaking. Adaptive cruise control will slam on the breaks when car is adjacent a pedestrian or bicyclist. The car car doesn't slow down as it approaches a pedestrian walking on the side of the road but slams the breaks on when the car is next to the pedestrian or cyclist. This unanticipated event causes the car to immediately drop in speed between 5 to 30 mph. Any motorists following will not be prepared for this illogical behavior and significantly increases the probability of a rear end collision. This behavior of the adaptive cruise control has also occurred when the car approaches oncoming highway traffic regardless of whether the highway is divided or not. In this event, if the driver of the tesla model y does not instantly take over complete control of the vehicle a severe rear end collision can occur. I have not addressed this with tesla nor have I taken my car in for inspection. I have been told by an owner of a model 3 and an owner of a model s that they have also experienced similar situations caused by the poorly calibrated performance of the tesla adaptive cruise control system. I have been forced to stop using the adaptive cruise control and auto-steer on my model y as this problem is on going.

The adaptive cruise control feature frequently hits the brakes despite no obstacles in the road. Major triggers seem to be: oncoming cars on an undivided highway at night. Oncoming 18-wheelers on an undivided highway at any time in day. Going over the top of a hill. Small bumps in the road at night. A large vehicle with blinking red hazard lights in view. (this will slam on the brakes and set the speed limit to 50 as it seems to think it's an emergency vehicle) blinking red traffic lights. Sometimes hov lane entrances will use a blinking red light to show that the lane is closed, and the car will slam on the brakes thinking it's an emergency vehicle. There's a risk of rear-end collisions caused by the sudden decelerations. Most of these events happened on highways with low traffic. No warning lights or messages were displayed before the events.

My wife was driving and had just enough time to cross over three lanes to get into the breakdown lane before the car came to a sudden stop. The car did not want to restart. We called the tesla service center and they were about to order a tow truck but we asked if there was a ‘ctrl/alt/del' type option. She had us select safety>power off. When our tesla came back on everything was seemingly normal so the service center said ‘this is very rare' and that it should be okay to drive. We drove another few miles down 93 and luckily took an early exit ramp because the car shut down again at the bottom of the ramp. My wife and I restarted the car again and managed to limp home in some sort of “power reduced” mode (I. E. Painfully little acceleration). This was potentially a very dangerous situation!

When using autosteer or adaptive cruise on i5, our car performed a phantom brake that cause the truck behind us to nearly flip over in order to miss hitting us. We were not in the lane by the divider, there were wide open lanes in front of us to the left and right by half a football field and no overpasses at the time. We slowed from 69 to about 39 before I could correct the braking. This happens so often we do not feel safe using the cruise control at all.

On a cross-country trip from washington, dc to oklahoma city on feb 5th and 6th (saturday and sunday) I tried to use the "adaptive cruise control" for the first time. Terrifying. The car would be driving along at 80mph, and then it would suddenly slam on the brakes, seemingly without provocation... With a 30-35mph sudden deceleration (absolutely nobody/nothing in either of the lanes in front of me). This was not while using the "full self-driving" feature, as I did not pay the extra k for this functionality, only the adaptive cruise control. Another very disturbing thing was that when the adaptive cruise control was enabled, it would not allow me to turn off the windshield wipers... And every so often the wipers would just start frantically wiping despite only a small bit of rain hitting the windshield (again, disturbing, as it is very startling when it happens out of nowhere). Needless to say, after this happened 5 or 6 different times over these two days, I turned off adaptive cruise control and kept it off. Tried to contact tesla service, but they kept dodging the issue so I stopped trying.

This issue has happened numerous times since I've taken possession of the car. The vehicle perceives a potential collision when no such potential collision exists. The car will suddenly brake while traveling down the interstate at high speeds (maximum speed limit). Fortunately, no one has been so close behind me that this has resulted in an accident, but it is only a matter of time. I took it in to a tesla dealership this week to have it looked at. Despite the adjustments made at the dealership, it happened again on my drive home from the dealership. I feel this automatic breaking system is unsafe. It also breaks suddenly at sharp turns or curves in the road, even at low speeds. It doesn't anticipate the turn and thinks the driver is heading straight into an obstruction. Part of the issue is learning to think like a computer and learning to anticipate what the computer thinks is happening as opposed to what the human driver thinks is happening. It requires constant vigilance.

While using adaptive cruise control on I-25 making round trips between albuquerque and ft collins, I have experienced numerous (dozens) phantom braking events. They are so frequent that I have stopped using adaptive cruise control. Almost all of these events occur when there is no traffic and no discernible reason for braking. In many cases, my first response is to look in the rearview mirror since I'm worried that if someone is behind me it would cause an accident since the stop is very unexpected. To date, there has not been a close call. The stopping varies between slight hesitations causing 1-2 mph decrease to dramatic decreases of over 20 mph. I have made numerous 'bug reports' using my voice in the car immediately after many of the events. I also scheduled a service call but was told that they examined the software and could find no problem. There is no warning of an impending braking event.

On multiple occasions the car triggers emergency braking when no obstacle is in front of the car, often at high speeds. The car is not equipped with radar, and relies entirely on camera-based adaptive cruise control. This is a safety risk and possible rear end collision cause. Due to the lack of radar, the vehicle also accelerates to desired speed slowly when using adaptive cruise control while on interstate. Often times resulting in traveling under the speed limit for an extended amount of time, causing a safety hazard.

The tesla model y had a software update at 12:05 am on feb 13, 2022, which was complete. I drove the car to local ymca at around 8:15 am on sunday feb 13, 2022, for my swim exercise and drove it home at around 9:30 am. I planned to park it by backing up to my driveway so that I can charge it. I positioned my car, with the front facing my neighbor's house. My foot was on brake and my right hand was moving the drive stalk towards r for reverse. The car all of the sudden flew forward on its own! It was only stopped after it hit my neighbor's house, making a big hole into her house, and causing severe damages to it outside and inside (smashed furniture and falling glassware), as well as to her landscaping. When this happened, my foot was still on the brake but pushing brake did stop the car. Additionally, hitting a tree also did not stop the car. Only the house and its strong frame stopped the car. The front of the car was totally damaged, including pieces falling out of the car and a big piece under the car falling down. Please come by immediately to take photos and examine damage. I called 911 immediately. The police and emergency trucks came. Since no one seemed to be visibly hurt (I had a whiplash and headache due to impact but was more was scared and shocked), the emergency medical crew left. The police said they are not making a report because the accident happened in private driveway and no crime was involved. I called liberty mutual to file a claim and was directed to file it online. I never bought the tesla autopilot package but the new software update showed autopilot is an included package. This is a problem. I called tesla customer service and reported this serious software malfunction. Thinking back, software problem caused another safety concern that started on feb 6, 2022.

Per previously reported cases, by tesla y suffers from “phantom braking” when I am using adaptive cruise control at highway speeds. In general it will decrease up to 20mph very suddenly. This is always in response to a falsely detected hazard; it will sometimes do the same when passing a vehicle that has exited an off ramp and has break lights on but is no longer in my lane of traffic. In general I drive with maximum 5-6 car lengths in my adaptive cruise control and this should not be happening. This has been an intermittent but ongoing issue through 2021; have not experienced in 2022 but have not done a lot of high way driving. Scares the heck out of my passengers. Love the car but please fix the software or it will be my last tesla.

While driving my tesla model y with cruise control activated, the vehicle would inexplicably brake/decelerate rapidly without any vehicle traffic in front of the car. It would occur at its worst while changing lanes, as I approached another vehicle from behind and attempted to change lanes to overtake. I would either be mostly in the other lane, or had already successfully changed lanes, when the vehicle inexplicably braked/decelerated. It was alarming, frustrating, and infuriating as it seemed clearly unjustified. This occurred while on the interstate, which was extremely dangerous given the speed traveling at as well as the number of vehicles that typically travel on the interstate. I have not used the feature since, and have even attempted to try and disable the feature while still being able to utilize some sort of basic cruise control feature, to no avail.

I am aware that nhtsa is investigating tesla over the emergency braking issue when using its advanced features. When I have read articles about this they always reference auto pilot or full self driving. I wanted to make sure you knew that this issue also impacted adaptive cruise control. When I brought my model y home in august of last year I quickly learned I could not safely use the adaptive cruise control. I live in rural ne iowa, and mainly drive on two lane roads. If I was on a downhill slope and meeting a vehicle with any kind of height to it the car would activate emergency braking, even though the other vehicle was completely in its own lane. It appears to me this issue has gotten better as updates have been issued the last six months and I have started to gingerly use cruise control again. It is common in the winter here to have tall piles of snow in parking lots. I also noticed on a sunny day I could drive right up to one of these piles when parking. It was striking that that huge pile of snow was invisible to the vehicle. Any other time I approach a barrier (e. G. Pulling in to my garage) it gives all manner of warnings and a visual indication of how far you are from the wall. This issue would be much more dangerous if an analogous situation occurred using autopilot or fsd. It is my understanding that for the 2021 y tesla went to just a camera based system (dropped lidar). I don't know if that is what caused these problems or not. The car is a joy to drive. But, tesla's habit of releasing updates and features to the masses before they are fully tested is dangerous in my opinion. There are more tesla's on the roads these days, at some point the accidents are going to add up. The ability to update systems that control how a car is operated/functions is relatively new. I would offer that the processes around how these updates are managed should be the subject of a separate investigation.

My 2021 tesla model y has two problems related to braking: (1) frequent unexpected and unnecessary slowdowns while driving on autopilot adaptive cruise control. The vehicle seems to believe something is in the road but it is not the case. This has been called "phantom braking" by many online reports. I experience this on nearly every drive where adaptive cruise control is engaged. (2) on one occasion the car locked up its brakes and began swerving to the left for no reason whatsoever. An alarm appeared on the screen and audible tones and a video was automatically saved. The event lasted only a second but would surely have caused a collision if another car was following me. The event occurred as I passed an oncoming truck on a two lane highway at night in good visibility. I was driving manually. Adaptive cruise control and auto steering were *not* engaged at the time. The extreme braking event was caused by the adaptive emergency braking (aeb) system.

After hearing of the "phantom braking" problem with the 2021 tesla model y I thought I'd add my observations. My car has rapidly, unexpectedly, and without other warning decelerated several times but always when the forward sensors apparently picked up a car crossing in front of me. Normally, I'd appreciate the help but it has happened several times when the crossing car was well in front of me and there was no cause for alarm from me and no way a tailing car should expect such a dramatic braking action. Tesla should certainly be asked to review this system and modify the braking action so that it is more gradual for distant cars or preceded by a moderate sound alert for concerning but not immediately threatening front-crossing cars. I should also note that the warning sound seems to go off at appropriate times as I approach stopped cars and it doesn't brake inappropriately when I approach stopped cars. The only problem I've noticed is cars crossing in front of me, mostly from my left to right, when I'm still comfortably distant from that car. Hope this helps.

I have owned two tesla model y's, this one from 2021 and a 2022 version as well. Both vehicles have exhibited the type of "phantom braking" that I have now seen described by several other owners. When attempting to use either the full autopilot system (which includes both adaptive cruise control and lane keeping assist), or when using just the adaptive cruise control (without lane keeping), the vehicle would brake suddenly and forcefully. This appears to be in response to a threat perceived by the car, but it would happen on totally clear roads, in great weather, without some of the typical false indicators experienced by "vision" based systems. It's noteworthy that both of my cars used the vision-only system, as this vehicle was one of the first ones that tesla produced that did not include a radar-based system. I experienced phantom braking so often with this car that I was completely unable to use cruise control. On a ~1,000 mile road trip through wyoming and south dakota (with minimal traffic in clear conditions on well-marked roads), I experienced over 100 phantom braking incidents in 4 days of highway driving. After that trip, I never used cruise control again regularly, but I would occasionally attempt to see if it fixed itself, and every time I would turn it on, I would have a phantom braking incident within minutes. I was able to capture a few videos of this behavior that I can send, as well, but I apparently can't do that as part of this form so please let me know how I could provide those, if required. Finally, the dates that I'm entering below are for the first occurrence of the phantom braking that I experience, but between the two vehicles, I have probably had it happen to me 150-200 times now. I have since sold the second tesla (largely to avoid these issues), but please let me know if I can provide more info. These cars are not safe right now, and I've been looking for a way to remedy that for a while.

This is super dangerous as it may not show the real time presence of another car, a pedestrian who is crossing behind your car as you back up, or an object. It also give the driver the false sense of being in the wrong place. We have two teslas, this is a model y and the other is a model 3. We have experienced the same problem in both since tesla pushed a software update in january. I notified tesla and asked for a repair. The response was that a software patch would be forthcoming. That was weeks ago. Again, this is a super dangerous flaw in the software for the display of the back up camera.

We are familiar with managing the controls which, in my experience, operate similarly to other vehicles with similar safety and driver-assist features. Unfortunately, in regards to the effectiveness and ease of operation of the tacc, our tesla is by far the worst of the 5 vehicles with which I'm familiar. The experience of managing tacc with oncoming traffic is frustrating, distracting and sometimes unsafe. Autosteer, because it builds on tacc's systems, is similarly deficient although the features it provides would be extremely welcome when tacc is improved. Nearly every oncoming large truck (including many pickup trucks) caused tacc to brake the car tacc assisted braking was inconsistent. Sometimes an immediate, slight reduction in speed (5-10mph) and other times it was an immediate major reduction in speed, on the order of half-speed within 3 - 5 seconds. It was common to have the car brake from 65 - 35 for no other reason than a large, oncoming truck. After 3 or 4 occurrences of heavy braking, I would turn off tacc and manually maintain speed with the accelerator. This in itself is fatiguing and I would eventually resort to a system in which I would disengage tacc when approached by a truck, usually 200 - 300 yds away and then reengage when traffic was clear heavy braking was severe enough that, if a there had been a closely following/unaware car, it would have rear-ended our vehicle tacc (and autosteer) seem "happiest" when following other vehicles and, even on 2 lane highways, phantom braking was much less frequent a standard cruise control (no traffic assist except for following distance) is not available but would be welcome summary: on the interstate highway system taac works reasonably well but could use improvement. On 2 lane highways tacc is more work and less safe than operating the vehicle manually and, as a system designed to reduce driver workload and improve safety, it fails.

The adaptive cruise control and lane assist on the tesla y models are defective and pose significant risk to drivers, occupants and surrounding traffic. Phantom braking and sudden slowing are common place and many times unpredictable. Countless times when oncoming traffic in the other lane approaches, sudden braking and aggressive slowing will occur especially if this happens to be a logging truck or larger vehicle. Coming under any overpass or bridge will also produce phantom braking. This will happen countless times in a single trip rendering the adaptive cruise useless. I complained to tesla and was called by the corporate office in denver and told that this is a reality and it was my responsibility to "teach the neuro-net" that it's phantom braking was an error by accelerating aggressively during those episodes and producing "bug reports" to tesla! I have had this tesla 3 months now and have stopped using the cruise control and lane assist because of safety concerns. My attempts at "teaching" the computer the correct response has utterly failed. I have had 3 episodes that I know of that someone following closely behind me had to take evasive action which precipitated "road rage" type behavior on their part for no fault of my own. Tesla has made no effort to correct this defect and have even cancelled my repair appointments stating it was"not needed". Every tesla owner I discussed this issue with has a similar experience. Eventually someone will get injured or killed due to this defect.

I've been having problems with phantom braking, primarily on highways. This problem has gotten much worse in the last month or two. The car will unexpectedly brake while either autosteer or adaptive cruise control are engaged while driving on the freeway, and typically (although not exclusively) when my speed is approx. 70-80 mph (where speed limit is 75-80 mph). This will happen approx. Once every half hour, although it is sporadic and often happens in spurts. Until about 1 month ago this would happen only while autosteer was engaged. However, during the last month or so ago this has also been happening while adaptive cruise control is engaged (without autosteer engaged). It happens most often when I am in the left lane passing a semi-truck which is in the right lane, although it happens other times as well. Always without any warning. It has happened a total of probably 20-30 times in the last 2 months (approx. 5,000 miles). Sometimes it manifests as a gentle, almost tentative tap on the brakes, whereas other times it is a fairly jarring with sudden hard braking. It has not caused any accidents or incidents, but I am concerned about it happening when a car may be behind me. Because of that, I will often disengage cruise control or autosteer if other cars are close behind me. My car software is equipped with full self driving, but the fsd (beta) has not been downloaded.

When using basic tesla autopilot (ap) on side roads or highways the car will experience “phantom braking” with no other vehicles around. Phantom braking is where the car will slam on the brakes because it sees a safety issue ahead. I was driving on a highway at 60mph and engaged ap after about 5 miles the car brakes hard and fast down to around 40mph and then sped back up to 60mph after about 50 yards. It did this twice on the drive home. If we have an 18 wheeler behind us and they're not paying attention they would definitely rear end our car.

This car is subject to frequent "phantom braking" . Using adaptive cruise control or full self driving, the car will occasionally brake hard for no logical reason. This happens every time I drive the car on two lane roads, I. E., with vehicles approaching from the opposite direction in the opposite lane. It happened from the time I took delivery until the present. It happened today (2-17-22). In 90% of cases, the phantom braking is triggered by a large vehicle - semi truck or bus, approaching from the opposite direction. In 10% of cases, the cause is either not clear, or caused by a smaller vehicle. The phantom braking occurs in all lighting conditions - right sunlight, overcase, night.

The cruise control on my model y frequently slams on the brakes for no apparent reason (no obstacle or vehicle in my lane). This happens at all speeds (from 30mph to 75mph). The cruise control is so unsafe and scary that I will not use it at all with other passengers in my car or when I have a car following me. My car slams on the brakes so hard it makes it completely unsafe for me and the people following me. In my opinion, it drastically increases the chances of being involved in a rear-end collision. There is no ability in the model y to use cruise control that is not adaptive-based. Until this problem is fixed, tesla needs to offer a cruise control option that is 100% controlled by the driver (standard cruise) where the speed and brakes cannot be changed by the car. My car has not been inspected by the manufacturer and this has not been reported to the manufacturer because it is a widespread and known problem, and tesla is not currently doing anything to help others who have reported the issue.

On almost all my long highway trips (about 4 hours long), if I have traffic aware cruise control (tacc) enabled on my tesla model y, I experience one or more episodes of phantom braking. The first time it occurred I had owned the car for only a few weeks and was not yet accustomed to its fast acceleration. I was driving at about 70mph on a clear day with no one in front of me when the car suddenly braked. My first impulse was to hit the brake to disengage tacc, but I realized that would slow down the car more, increasing the chance I might be rear-ended. So I hit the accelerator and rocketed back up to 80mph before settling back to normal speeds. I was fortunate to be on a straightaway with no one ahead of me. Since then I have experienced phantom braking with tacc enabled under similar circumstances, I. E., with no cars or trucks in front of me and in clear weather in daytime. With more experience, I have noticed that the problem happens more often when I am passing a truck on the highway, especially when doing so around a curve. In past years I have driven numerous rental cars with adaptive cruise control and have never experienced anything like the phantom braking of the model y. This is not normal behavior and I hope you can get tesla to fix it.

I have had issues since I purchased this vehicle in march of 2021 where driving down the highway with adaptive cruise control enabled and it will suddenly slam on the brakes at highway speeds with no other vehicles around. This sudden braking is so severe at times that everyone in the car is thrown forward and bracing for a false impact. This has caused several close calls for vehicles following me. Also the severity of the braking in winter weather causes the vehicle to lose traction and potentially place all the occupants and others on the road at risk. During my time in the fsd beta program I was able to report all of these events, sometimes dozens of times a day. Eventually I asked to be removed from the program as it seemed worse in the program than when on a standard build version of the software.

I've had this vehicle since june 2021 and experienced times when it would automatically brake abruptly, as if I were about to hit the vehicle in front of me. The first couple of times, I thought it was something I had to calibrate within the digital dashboard, but realized that it wasn't something that could be adjusted — it was just the vehicle's way of using it's sensors to prevent me from colliding with the vehicle in front of me. The problem is that I wasn't ever in danger of hitting anything in front of me. There were even times when I was gradually braking, but the vehicle automatically took over and broke for me. The painful part of it is that when this happened, it was so sharp and abruptly braking that I could feel my head jerk forward. It wasn't until recently that I learned that this is actually a very big problem experienced by many other tesla model y owners — called “phantom braking”. I've also had many other issues with the vehicle's operating system, and have had to bring the vehicle in for tesla service 5-6 times within a period of 7 months of taking lease of the vehicle.

Per tesla, the car was not at fault and the car functioned as intended but it was driver error. With all the safety features that this car has, why did it not sound a warning or apply brakes to prevent this from happening. I have read about hundreds of thousand's of incidents of sudden unintentional acceleration but yet nothing has been done about it. There is another problem with phantom braking when the car suddenly stops if you use the cruise control. I do not use cruise control because of this problem. Tesla continues to add games and other nonsense but have done nothing to fix these problems. I reported this to the minnesota attorney generals office and they suggested that I contact the nhtsa.

We've taken this vehicle on long interstate road trips through the mountain west before, and never encountered this problem before in similar circumstances.

When using the cruise control (and, by extension, autopilot) feature, the car often brakes unexpectedly and in some cases dramatically for no obvious reason. I often use cruise control on single lane undivided roads that have speed limits between 35-50mph. When using cruise control in this scenarios the car will often automatically apply the brakes for no obvious reason, often applying the brakes hard enough that the car slows down quickly. Many times the forward collision warning sound is played but there is nothing in front of me in my lane or in the opposite lane. Other times this happens when a car is approaching me in the opposite lane. There have been several cases where the car applied the brakes for no obvious reason so hard that had I not intervened (by pressing the accelerator) the car behind me would have been at risk of hitting me. It has gotten to the point where I am becoming somewhat conditioned to override the automatic braking anytime it happens. That is dangerous and can lead to an issue where the car legitimately has a reason to decelerate but I override it thinking it is braking for no reason. I see this behavior in both cruise control (which tesla calls traffic aware cruise control) or in autopilot. I don't currently have the full self driving feature of the car. It occurs most often when I'm on a single lane undivided road using either cruise control or autopilot. When I'm using cruise control or autopilot on a traditional divided highway the unexpected braking happens much less frequently.

In september 2021 I was driving my tesla model y on I-84 in connecticut at around 8:30pm, when all of a sudden I felt like I was about to faint, started experiencing dizziness and felt like everything was spinning around me. Luckily I was able to pull over safely. I called for an ambulance, everything checked out fine. After that I went to an er, everything checked out fine again. I thought I was having a heart attack or a stroke, but all the tests came back negative. Initially I thought maybe it's because the tesla drives, that it accelerates so fast that I wasn't used to the speed. Weeks later I started to see various specialists, ent, allergist, ophthalmologist, optometrist, neurologist, they all checked me out and said nothing was wrong with me. I had two mris and and mra done on my brain and neck, nothing wrong with me. After that I started thinking if there might be something wrong with the model y, so I googled to see if other tesla owners experienced the same thing. Then I found that some teslas (model x and y) are known to have distortions and in some cases can cause headache or even vertigo for people. I then looked through my model y's windshield, then I noticed several areas of distortion. This led me to believe that my near-fainting was caused by the distortions in the windshield. I have other cars and I have driven highways at high speeds and I have never experienced any kind of dizziness or fainting. I took my model to tesla service center, they agreed and admit they do see the same distortions I saw, but they claim the distortions are within manufacturing specifications. I requested for the windshield to be replaced, ended up paying over

There was a truck approx. 150-200 ahead of us and in the lane to our right. I was driving in autopilot. All the cars on my highway were headed in the same direction all headed west to chicago. So the phantom braking was not triggered by a truck in an opposite-headed lane. It was triggered by a truck headed in the same direction and to the lane to my right- the same exact scenario as what happened on feb. 1st. Almost identical configuration. I was doing about 60- frankly paranoid that the car could stop throughout our whole trip home. Sure enough, when we approached the arrangement where a truck was ahead and to the right of our lane, the car suddenly braked. Luckily there was no vehicle tailgating us. So that's it.

This is 100% false, if you allow fsd to drive, it will fail almost 100% of the time in very quick succession. From lane change mistakes, to turning mistakes, not staying within its lane in a consistent manner, not putting the car into left turn lanes or stopping at green lights, which in itself is dangerous.

We went from 65 to almost 0 in a split second and if my wife and I weren't wearing seat belts we would have been very seriously injured.

I commonly will experience phantom breaking driving on two-lane roads, particlualy when meeting oncoming traffic. This occurs most commonly at the crest of a hill or when meeting trucks. It occurs nearly 100% of the time when meeting trucks at the crest of a hill. There are also random occurrences on flat roads with no other vehicles and no shadows or bridges. It also occurs on bridges and occasionally with shadows. Performance has been better on four lane roads with more traffic. It's as if the system needs to have other traffic to gauge itself. With no traffic on four lane roads, phantom braking will rarely occur. There is no single date of this occurrence. It happens all the time.

The tesla has been doing phanton breaking. For example on the highway using dynamic cruise control or autopilot. When a truck is merging to the right lane it will apply quite the break force. Almost got rear ended cause of this on the highway. Observed this a few times on drive from ga to nj. I also noticed going up and down hills with dynamic cruise control it will sometimes trigger the front collision warning or phanton break. This seems to be sporadic and doesn't like one lane back roads. Last and it least I also noticed that using auto pilot the car forces you to use auto high beans. On the highway at night it will go off and on a lot to the point drivers on opposite side of the road would flash their lights to let me know about the high beans. The model teslas doesn't use radar or laser sensors like previous year. It does seem to have a lot of impact cause I did not see these issues with my lexus rx350 with dynamic cruise control, lane keep assist, auto high beans, and front collision warning.

From june, 2019 to june, 2021 we owned a tesla model 3. We have had the model y since june, 2021. The current model y has a significant phantom braking problem. Worse than the model 3 that we owned. Our model y relies on "tesla vision" without radar. Last week we drove 1,400 miles from montana to southern california. On more than a fifteen occasions phantom braking occurred, to the point that we were reluctant to use it. Driving on an interstate at 80 mph, the car would suddenly brake. The 1st reaction is to overcome the braking with acceleration. On one occasion when there was no traffic behind, I didn't accelerate until 45 mph. From 80 mph to 45 mph suddenly. Dangerous. On city streets we also experienced phantom braking, yet not so dramatic. Some thoughts on what causes this issue: pavement glare, a change in pavement color, concrete barriers on an overpass, reflection from on coming traffic. Traffic assisted cruise control is an important feature for me and now I'm reluctant to use it.

Description
The defroster system is not able to keep the windshield clear of ice buildup when driving even in light snow. This is because this is an electric vehicle, so there is no engine heat from underneath the hood to radiate towards the wipers. Between wiper cycles, the wipers rest below the area of the windshield that is heated by the defroster. During snowfall ice builds up on the wipers from their resting position between cycles and that ice then propagates to the rest of the windshield as the wipers move. This is an extremely dangerous situation. I heard tesla is installing a heater beneath the resting area of the wipers on the 2022 model year of this vehicle. However, nhtsa should issue a recall and require this heating plate be retrofit onto earlier model years. The country of canada is aware of this issue as well and currently investigating it.

As I approached an overpass that was casting a shadow across the highway, the car suddenly braked hard. Fortunately there were no vehicles immediately behind me. If there had been, I likely would have been rear-ended. About 15 minutes later, while driving in the middle of the three northbound lanes, a motorcycle passed me on the left and then cut across my lane to get to an exit. Again, the car braked suddenly. When I next stopped to charge the vehicle, I went online and read on various tesla user chatrooms that this was a widely experienced problem.

(1) my car dangerously and aggressively applies the brake dropping the speed of the car between 3 to 30 mph within a second or two (phantom breaking) every single time I drive the car in adaptive cruise control or auto steer. This happens on 2 lane roads, on divided highway, driving on straight and curvy roads, when there are shadows, frequently when a truck or car is coming toward me, and even on overcast days when driving on a freeway when there are no shadows and no traffic in either direction. The car seems to be sensing an object that is going to cause a collision and applies the brake even when no object, threat, or shadow is anywhere in view in any direction. I frequently have to immediately step on the accelerator to keep from getting rear-ended in what could be a severe or fatal accident. (2) on a 225 mile drive to the tesla service center to correct the phantom braking problem, my car inappropriately applied the brake 40 times, including aggressively dropping the car's speed from 63 mph to 35 mph in a second or two. (3) my car dangerously and aggressively applies the brake whenever a car is turning in front of me that is sufficiently far enough away that there is no absolutely no threat whatsoever of a collision. I then have to quickly step on the accelerator to keep from being rear-ended. (4) I have taken the car into the tesla service center twice to correct this problem. I even gave them a list of dozens of times/dates I experienced phantom braking and the # of mph the car slowed (I recorded this on paper and as "bug reports" on the car's computer). On one visit the technician spent 12 hours reviewing my bug reports and the car's operation. In both of my service center visits the bug reports were sent to a tesla engineer for review. After both visits to the service center I was told the technician and the engineer could find nothing wrong with the car and “it was working as designed.” (5) in conclusion, my model y has a severe safety defect.

Automatic emergency braking. Known also as "phantom braking." tesla is aware of the problem. Regardless of whether or not I'm using the standard cruise control or the more advanced full self driving feature, the car routinely hits the brakes even when there is no obvious obstruction in front of it. If the car suddenly brakes on the highway with another car behind it, it risks a rear end collision. No other warnings appear. The car simply brakes for no reason. This automatic emergency braking system should be removed for standard cruise control. It's more of a hazard than a benefit.

In short: phantom braking while driving on single lane highways with autopilot enabled my car slams on the brakes and alerts whenever a semi is safely approaching. What component or system failed or malfunctioned, and is it available for inspection upon request? - I assume the tesla vision system + autopilot are what fail in this scenario. How was your safety or the safety of others put at risk? Immediately this puts us in risk of a rear end collision. Alert fatigue from false alarms creates a long term risk as drivers are trained to ignore / cancel alerts. Has the problem been reproduced or confirmed by a dealer or independent service center? Not explicitly. We have mentioned it to a dealer and said it was a common complaint. Also it is a well known (under addressed) issue amongst tesla owners. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No, given the lack of property or personal injury it doesn't seem right to alert those institutions. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No, all systems appear to be functioning correctly. That is a large part of the problem - if the tesla autopilot is unable to function reliably on one lane highways it should at least warn drivers.

My tesla model y seems to be suffering from what is called "phantom braking". My vehicle was produced shortly after the radar was removed and tesla went to a camera only system. My car has the lasted updates installed. It is not a full self driving vehicle. Since I purchased the vehicle it has had a problem during low light or sunny conditions with suddenly braking when using the cruise control. The situation has been reported to tesla multiple times and "bug reports" were recorded and reported to the service center. During one morning drive of about 35 minutes I reported 8 occurrences. Sometimes the vehicle will sound the emergency avoidance braking. The car will suddenly slow from 60 to 30 mph. On multiple occasions the vehicle behind me had to take evasive action to avoid rear ending me. During one of my service visits the vehicle was taken on an extended over night test drive and the technician confirmed the problem. During the other visit the service center did not even take the vehicle for a drive. In both cases tesla said the hardware was functioning normally and this was a "normal" operating condition for the vehicle. The car does better if I am following another vehicle because it seems to be able to maintain it's depth perception better if it has that reference point. I did report to the service center that the car seems to follow closer at night, even at the max following distance setting. The vehicle also struggles with the automatic high beam headlights which the computer turns on automatically if cruise control is activated. Very often the car is slow to turn the high beams off but in other cases it will turn the high beams off and then turn them back on as another car approaches.

I have experienced several instances of the phantom braking in my tesla model y. It primarily happens when I'm on a two-lane road and there is a large truck approaching on the opposite lane. However it will also phantom brake on a highway where there are two lanes going in one direction separated by a median with two lanes going the opposite direction. It seems to happen when it's coming up on a slight hill, where you cannot see over the hill. The car will slam on the brakes in the middle of the freeway, which when going at speeds of 65 to 75 miles an hour when traveling with other vehicles going the same speed, it can be especially dangerous in texas where the giant pick up trucks like to tailgate electric vehicles. In one instance the pick up truck behind me thought I was brake checking him and jamming on my brakes to be a jerk; he then “coal rolled” me, putting out a giant cloud of black smoke. This situation has made it so I am afraid to use traffic aware cruise control, which I need to be able to use on road trips. It is especially bad in the two-lane winding roads around amarillo, texas, but I've also had it do this on a much larger road that goes through chandler, new mexico to colorado. I absolutely love my tesla, but the phantom braking is concerning, and the response I've gotten from tesla service is that the car adapts and will eventually learn where not to do it. I don't know if that's true or not, but it doesn't seem to be getting better, and it does it at the same locations on the road. I need cruise control to be working. Another suggestion might be to have the ability to turn off traffic aware cruise control. I paid for full self driving but have not had the courage to apply to use it because of phantom braking. I would also like to see federal laws passed to address coal rolling of electric vehicles. It is extremely dangerous and it's happening a lot in texas.

I'm experiencing “phantom braking” in my tesla model y. I live in a rural area where 2 lane roads (1 lane each direction) are the only roads around. Larger pick up trucks, pickups with trailers, busses, semi trucks, dump trucks, sprinter vans, and other vehicles of that size in the opposite lane trigger my vehicle, when in cruise control, to slam on its brakes. This happens when it's sunny, cloudy, any type of weather condition. Occasionally, when in cruise control, I notice the car makes slight braking attempts, even when there is no traffic in the other lane. It's as if it's sensing a ghost it doesn't want to hit… this has happened ever since we purchased the vehicle. I do not use auto pilot because I do not see the point where I live. This issue happens when using the adaptive cruise control. I have not noticed it when using auto pilot as, mention before, I rarely use that feature. I recently say articles where many other tesla owners were having this problem so I thought I would add to the awareness of this issue. My wife does not use cruise control nor auto pilot for fear the car will slam on it's brakes and someone might rear end us. Speed limits range from 35-55mph in my area.

Description
The vehicle driver assist system frequently has phantom braking in situations it should not be, especially when there are vehicles behind putting us at risk for a collision due to unexpected braking behavior of the car. This happens especially in setting of 2 lane roads with oncoming traffic, and guaranteed with a truck in the vicinity. On major highways it is less so, but does still happen occasionally. On local roads even if straight and no obstruction the automatic braking without notice occurs when least expecting. Also the lane departure system disables automatically for the remainder of a drive if you veer off a lane even once and didn't take the corrective action the vehicle thinks should have happened. That's not how a safety feature should work... It should remain on regardless. As much as I do enjoy this car, these quality issues definitely make you second guess and keep a closer eye on how you drive to avoid accidents if the system decides to not work as advertised

This car has had numerous phantom braking incidents. It is unusable on 2 lane roads. It breaks suddenly for trucks in the opposite lane. It can also begin to brake for cars in the opposing lane. The only remedy is to press on the accelerator to turn off the autopilot. It also slows down periodically for shadows (for example when going thru an underpass). It was reported to tesla service and evidently nothing can be done since it seems to be a software issue. I am unsure of that since this car no longer has the radar that previous versions of this car did have.

The tesla adaptive cruise control has been malfunctioning for the past 12,000+ miles (since new). Yes, it is available for inspection upon request. When the cruise is set, there are a significant number of phantom breaking events, making it a real hazard for anyone following our vehicle. The breaking can happen as often as 3 times every minute, and can decelerate 10-15 mph within seconds before I am able to react and override the cruise. The vehicle has been inspected 2 times by the manufacturer and has been found to have no hardware failure. There is no warning prior to the phantom breaking. However, periodically there are warnings during the phantom breaking events in the form of alarms sounding.

I have a 2021 tesla model y. Washing post reported an increase in phantom breaking recently. It's not just recent. I took delivery of my car in may 2021 and quickly learned that when in cruise control this car will randomly apply the brakes - at times going from 70's to 30's very quickly. In a simple drive from las cruces, nm to albuquerque, nm with no traffic on the freeway the system will throw on the bakes while in cruise control at least 6 times. And it's repeatable. You simply cannot use cruise control on the free with any traffic for concern of the system engaging and causing an accident.

When using autopilot, I experience multiple, repeatable phantom braking issues on a regular basis. While it is worse on two lane highways, I've also experienced the issues on separated freeways and interstates. The phantom braking varies from a minor throttle response to decrease speed to full emergency braking that drastically reduces the speed at a rapid pace resulting in unsafe driving conditions for occupants of my vehicle as well as those who might be following behind me. Situations that seem to trigger the phantom braking include cresting a hill with oncoming traffic, navigating a turn with oncoming traffic, a larger than average vehicle (commercial truck/tractor trailer) approaching in the opposite late, shadows cast by large trees or overpasses, and changes in pavement color - for example, transitioning from gray concrete to black asphalt.

Description
On a recent trip to minnesota when adaptive cruise control was engaged there were several ( >10) episodes when the car would suddenly decelerate for no apparent reason. On a two lane highway it might occur if a large vehicle such as a truck was oncoming in the opposite lane. On the interstate, the common scenario was traveling in the right lane going up a slight upgrade with a car passing in the left lane. Often the sudden speed reduction was 25 mph or more. On occasion even on a flat section the car might suddenly brake for no apparent reason. On one occasion this happened in the afternoon going west with the sun glinting off some shiny asphalt crack filling. No accident occurred, but if a car were following closely, sudden braking could cause a crash. Because of this erratic behavior I don't use adaptive cruise control except for short distances. This is a known tesla problem, but it seems the company is more interested in enhancing games to be played while charging rather than attend to a major flaw.

Description
A well known phenomenon of "phantom breaking" occurs frequently and without warning with the traffic aware cruise control engaged. This occurs not only on 2 lane highways, but even on undivided and divided highways. On the 17 mile commute to work everyday, this will occur 5-10 times, which results in rapid, unanticipated deceleration. At the time of these deceleration events, there is no visual cause to the driver that would have resulted. Often it appears to be activated by oncoming traffic lights, lights on the side of the road at businesses, when cresting the road, and when the road naturally has a bend or swerve in the traffic pattern. These rapid deceleration events place the occupants at risk of rear end collisions and also are uncomfortable as you must immediately place your foot on the acceleration pedal, which results in a jerking movement to the occupants. Telsa needs to either employ a "dumb" cruise control or greatly improved their tacc system before continued use of their system.

The car seems to think the speed limit has reduced, leading me to believe the car is reading the overpass speed limit, not the highway, and adjusting. On another highway, after a steep decline there is an incline. At the end of the decline, the car slams on the breaks as if it thinks the incline in the road is an obstacle.

While on a 475 mile road trip, my vehicles emergency brake system was activated while using cruise control on more than one occasion with no visible hazard ahead of me. This caused my car to brake at speeds upward of 70 miles per hour on two lanes highways, leaving me to fear that any car behind me could easily rear end me and harm me or my children who were in the backseat. On another occasion during this same trip, the weather began to turn. Snow began to fall heavily leading to poor road conditions. My model y activated corrective steering twice at speeds of 10-20 miles/hr, both times attempting to swerve my car into the lane next to me occupied by a semi truck.

I have experienced many episodes of sudden, unexpected and seemingly inappropriate strong braking. The most common circumstance is overtaking semi truck/ trailers that are slowly ascending the mountain slopes of interstate 5 in southern oregon. Often the trucks have their emergency flashers in use. It self-brakes from 65 mph down to perhaps 30-35 mph and I "take over" by depressing the accelerator. It also happens frequently with oncoming traffic on 2 lane highways night or day and usually on a curve. The problem is frequent enough to avoid using cruise control on 2 lane roads and on I-5 mountain grades. It happens reliably on my way to town where an intersection has a flashing light and the approach is downhill into a right hand turn. It does not happen travelling the other direction and does not require any other traffic. For all of these, the sudden braking puts myself and others at significant risk for a rear-ender" collision. There are no lights, warnings, or ability to learn what triggered the inappropriate braking. I do not have the full self-driving option on this vehicle. A call to tesla for service concludes with, " there are no faults with any of the hardware in the vehicle and these behaviors are a limitation of software in the system at this time". I did not take it to them to look at the car as it is 5 hours of driving plus the service time to do so.

The backup warning system did not work when I backed out of a driveway on a dark night. I knew there was a black car (sedan I believe) parked along the curb across from the driveway, and could partly see it in the backup camera when the tail lights would turn on (I. E., when I stepped off the drive pedal), but was unable to tell exactly how close I was to the car. There were no beeps from my car to warn me. My car stopped abruptly as the edge of my trunk lid hit what I guess was the corner of the other car. All damage appears to have been to my car - a dent in the trunk lid. I reported all of this to tesla through their service app, and received a list of places from which I can get an estimate to repair the damage, but never received an explanation from them of their evaluation of the car's records I want to point out that I believe my tesla includes all camera sensors - a change they apparently made over the summer. My car was ordered in june 2021 for september delivery.

Tesla recently overhauled the firmware to their vehicles, however the newest update removes much of the ease and functionality. They have removed defogger buttons into the background, and other settings as well, causing the user to have to use multiple touches to work something that previously was quick. I believe this to be a safety issue. Drivers are now unaware where certain settings are and causes drivers to become distracted from the road to a degree that is unsafe while driving.

With tesla's new software version 11. 0 (firmware 2021. 44. 25. 2), the enabling of the front and rear window defogger is not readily accessible (they are buried in a menu). In the previous version of the software, there was a dedicated button on the screen to enable each of them. This is a safety issue because of the following scenario that happened to me today, comparing to my experience just the day before: I was driving in the mountains of colorado, where it was below freezing and snowing. On the 22nd of december, before the software update, my front window started fogging up very quickly. I was able to turn on the front and back window defoggers with one tap. Today, I was driving back and the same thing happened — the window started fogging up. With the new software you had to tap twice, taking away your attention from the road in order to locate the defrost on button. This is incredibly dangerous. I opted to move to the side and put my flashers on while I did that.

Traffic aware cruise control is just about useless on 2 lane highways. Once enabled it is plagued by frequent decelerations for absolutely no obvious reason. What is more concerning is the application of emergency braking when meeting an oncoming truck, even on a well marked highway where the truck is centered in it's lane. Fortunately this has not happened to me while I was being followed by a vehicle, but it is highly likely that a large truck or inattentive driver would have rear ended me in this scenario. Tesla service has looked at my car, and told me that everything was working properly, that it was a common complaint and they did not have a fix.

When driving on a two lane road and approaching an oncoming 18 wheeler the cruise control consistently slams on the brakes and I am concerned about the well-being of my 5 and 4 year old in the back seat. It whips them forward. I am also concerned about cars following me and getting rear ended with the force it is applying this phantom braking. I called tesla and they said this is expected behavior and it might be fixed in a future firmware but no guarantees. I think this is an unacceptable answer regarding the safety of my family.

Description
When cruise control or autopilot systems are active, the car will often slam on the brakes and sound an alarm as if there going to be an imminent collision, even thought the lane is clear in front of the car. This happens most likely often when cresting small hills or on curves. There may be a car in coming in the opposing lane, but there is no danger as the opposing car is fully in their lane. The adapative cruise control or autopilot system decreases the speed very quickly, often reducing the speed by 10-20mph within seconds. This causes panic for the driver and any cars behind us have to suddenly slam on their brakes, creating a dangerous situation. I own both a 2021 tesla model y and a 2021 model 3 that both have the tesla vision camera based cruise/autopilot/collision detection system. This problem has gotten worse as tesla has released new firmware updates in recent months. Many tesla owners are reporting that they are having the same issues recently. Tesla's response is that the systems are under development and that they will improve over time. The problem is that this is a safety issue now! They seem to be overly focused on developing and testing their full self driving systems that they are ignoring a huge safety flaw in their current cruise control and autopilot systems.

On monday november 22 at around 6:15 pm cst, I was driving my model y and had tesla's full self driving beta software engaged. A right banked curve on a two lane road in a rural area came up with a vehicle coming around the curve the opposite direction. The model y slowed slightly and began making the turn properly and without cause for concern. Suddenly, about 40% of the way through the turn, the model y straightened the wheel and crossed over the center line into the direct path of the oncoming vehicle. I reacted as quickly as I could, trying to pull the vehicle back into the lane. I really did not have a lot of time to react, so chose to override fsd by turning the steering wheel since my hands were already on the wheel and I felt this would be the fastest way to avoid a front overlap collision with the oncoming vehicle. When I attempted to pull the vehicle back into my lane, I lost control and skidded off into a ditch and through the woods, causing significant damage to the vehicle. I was able to retrieve the dashcam footage of this incident and it is attached here. I did analyze the footage myself briefly. You can see the vehicle leave the lane, and within about 10 frames, I had already begun pulling back into the lane before losing control and skidding off the road. Since this video is recorded at about 36 fps, this would mean I reacted within 360ms of the lane departure. I understand it is my responsibility to pay attention and maintain control of the vehicle, which I agreed to when I enrolled in fsd beta. I was paying attention, but human reaction does not get much faster than this and I am not sure how I could have otherwise avoided this incident. I am thankful this was the outcome rather than a front overlap collision with the oncoming vehicle, which would have likely resulted in bodily injury. Tesla has confirmed that fsd beta was engaged, per the attached correspondence, but insists that this incident and the resulting accident are my responsibility.

While driving my tesla model y using cruise control, the vehicle will continuously brake suddenly for unknown reasons. In several instances, I was worried that the car following me would either hit my car or be forced to take other actions, possibly causing an accident. The system is dangerous and useless. When I contacted tesla regarding my concern, they said something about the software program evolving…no fix available. I have had my tesla model y in their service center three times and have had numerous phone conversations with them and their customer service department regarding this issue. They said they simply cannot do anything about it. Again, the cruise control system is extremely dangerous. Please require tesla to resolve this problem immediately. Thank you.

On two occasion, our brand new tesla model y lurched forward from a complete stop. The first time, on 2021/10/09 at 4:36pm I was at a car wash and trying to put the car in neutral. Fiddling with the gear selector, the car jumped forward without me touching the pedals. I hit the breaks and neither the car or anyone else was injured. The second time, on 2021/10/25 at 8:10 am, my wife was dropping off the kids at school. At full stop the car lurched forward again without her touching the pedals or the speed controller. The car hit the car in front of it 3 times with force. The car as well as the two other cars in front of it got seriously damaged. My two year old son was on board, there was many middle schoolers around but thankfully no one was injured. Incidents were reported to tesla right away who has assured us they would investigate but we have had no update since despite contacting them multiple times. They assured us they have the ability to download telemetry remotely but I am concerned that as time goes by data will no longer be available. We later got an alert on the app that the emergency braking system had been disabled at the time of the second incident. I have videos files, recorded by the car itself of both incidents as they are happening available. The body damage of the car is fully repaired but the car is otherwise available for inspection/data downloads.

My wife and I purchased our tesla model y back in february 2021. We picked it up back in may 2021. The selling point for us was how it drove in the winter since we live in central wi. When we test drove the car in a snow snow at the highland park dealer. The car handled great in the ice and snow due to the car having the winter driving option. My wife nearly got into an accident due to no longer having the option for winter driving. The regenerative braking option is great until you drive in winter conditions. Ice and snow will cause the vehicle to slip and slide whenever letting off the throttle. The safety concern is that if a line of vehicles is in front of you and one person slams on the brakes letting off the throttle is essentially the same thing as slamming on your brakes. Which you never do while in a snow storm. We essentially bought the vehicle with and for this option to to control the vehicle better based on weather conditions. Removing the the winter driving option was not only wrong but a law suit waiting to happen due to the safety issue it brings.

While driving on an interstate highway (75 mph) at about 12am (little traffic) on four separate occasions, with cruise control engaged, the brakes were unexpectedly applied without warning, no forward traffic, no wildlife, no vehicles on the side of the road. Had there been a vehicle behind us, it could have resulted in a rear end collision. Several days later, on a two lane road (55 mph), cruise engaged, with oncoming large delivery/semi vehicles, again, the brakes were applied as if it was an imminent collision - which it was not. We have not seen any warning lamps, messages, warnings - however, we are new to this vehicle and not sure where we would see such a warning. After the latter event, I contacted tesla service but was told it is an issue being looked at however there were no fixes available at this time. I have not driven with cruise control since as I am very afraid of being rear-ended.

Tesla's autopilot / adaptive cruise control / emergency braking is defective. On multiple occurrences I have had incidents where the vehicle's adaptive cruise control and automatic emergency braking systems have activated inappropriately. In one occurrence I was driving on I-17 through phoenix in the middle lane. I was beginning to pass a pickup truck pulling a trailer (my front bumper was just behind the trailer) when the car detected this as an imminent collision and applied significant braking. I had to use the accelerator to disable the emergency braking, and this triggered a number of cars behind me having to brake as well. In a second occurrence I was driving on sr-74 westbound in phoenix between I-17 and lake pleasant parkway. This is a two lane road in many sections, and at one point I had a semi truck and trailer coming towards me in the opposite lane and my car detected this as infront of me and applied emergency braking. Thankfully there was no one behind me as the vehicle reduced speed from 65 to 40 before I was able to push the accelerator and resolve the issue. There have been other incidents of it braking in ways that were unexpected and dangerous. What component or system failed or malfunctioned, and is it available for inspection upon request? Auto pilot / adaptive cruise control / automatic emergency braking how was your safety or the safety of others put at risk? See above has the problem been reproduced or confirmed by a dealer or independent service center?

When traveling down a clear road with no obstructions, the tesla will unexpectedly put the brakes on, sometimes mildly and sometimes severely when the speed sensitive cruise control or the autopilot is engaged. This is not tesla full self driving, just standard cruise. This is a known problem that tesla is aware of and has not addressed. The problem has become much more pronounced in recent software updates. This happens frequently and sometimes causes an unsafe condition causing me to not want to use this feature while driving at all.

The autopilot randomly applies the brakes. Sometimes it applies the brakes on a 2 lane highway when a truck or large vehicle approaches in the oncoming lane. Other times nothing is in the lane and it slams on the brakes. Other times the forward collision warning starts making noises and nothing is in front of me. I took the vehicle in for service, but of course the tesla tech could not duplicate. Although the invoice says "autopilot will improve as firmware is released."

Adaptive cruise control breaks hard for no apparent reason. If there had been any cars trailing close behind I could easily be rear-ended. Happens at least once every time I turn on cruise control. On a recent longer highway trip of about 90 miles it happened three times. One time on that trip it happened while passing under a bridge, did it pick up the lower speed from the bridge above? The other times it seemed to happen for no reason. All these times our hearts dropped (2 passengers in car). Note that I do not have full self driving, so I'm talking about adaptive cruise control being the problem.

When driving with cruise control engaged, the car repeatedly brakes very hard. Sometimes the braking is when there is a car in the opposing lane and is approaching but not over the line. Sometimes the sudden hard braking occurs for no apparent reason. But on a two lane highway this occurs very regularly. It occurs several times an hour. This is a serious problem because if there is a car behind me the sudden hard braking may cause that car to crash into me from behind. You can submit a bug report to tesla by pushing the right hand steering wheel button, saying "bug report" and then describing the report verbally while driving. This will include all sorts of driving data being sent to tesla. I have done this dozens and dozens of times. Each time I get a message on the screen thanking me for sending in the bug report. Never once have I ever heard back from tesla other than the instantaneous message on the screen saying that the bug report has been submitted. I believe that tesla has had a recall for a very similar problem with the model s and model x with full self driving. This recall was fixed almost immediately with an over-the-air software update. However my problem does not relate to full self driving (which my car does not have). This relates only to cruise control. I have spoken to several other model 3 and model y owners who all report the exact same problem. A quick search online will reveal hundreds of other similar reports for model 3 and model y owners who do not have full self driving. I believe this is a very serious safety problem and needs to be addressed immediately. Regards, ken maples

When on cruise control or using autopilot mode, there are frequent phantom breaking issues. On a long trip, we experienced phantom breaking consistently on the highway both at night and during the day. These phantom breaking issues would sometime be significant and immediately drop speeds 10 miles an hour creating a danger of surprising people behind us. On a 2 lane country road, the issues are greatly compounded. The breaking would constantly trigger with oncoming traffic in the other lane and break very hard with the auto break alarm sounding. At night on a country road, it occurs with almost every oncoming car. It is amazing to me that this made it through quality control because it is easily reproducible. The auto braking feature should just be turned off for country roads if this can't be fixed. At one point, I was right next to an older model 3 on a mountain passing lane when an oncoming car was coming. The model 3 was in the left lane closer to the 'danger' and my car phantom braked with the auto breaking alarm coming on and the model 3 just continued on, no issue. No idea if they were on cruise or auto pilot etc.

On september 26, on our first long distance trip with our just delivered (9/17/2021) tesla model y, during daylight nice weather driving with adaptive cruise control switched “on”, on at least 6 occasions (strait roads, freeway and non-freeway driving), the car suddenly, without any reason, violently slammed on the brakes. These events are hair raising for me and passengers, let alone for a driver behind me. If he/she does not pay attention at that very moment, the result could even be disastrous. I would never have expected such a serious safety issue with a tesla. Suffice to say that this is absolutely unacceptable to me. When checking out the web, many people reported similar issues with their model y vehicle. I had the car checked-out at the tesla lynnwood, wa, service center on september 30, 2021, and when picking-up the car I was informed that no anomalies had been found. At later dates, similar emergency braking occurred without any reason, while driving with adaptive cruise control. Obviously, I do not trust this cruise control system one bit anymore, and no longer use it. I have written a letter to tesla (11/12/2021) requesting a time frame when a solution can be expected, but so far, I have not received any word from them. I sincerely feel that tesla should temporarily disable this adaptive cruise control feature on all model y vehicles currently on the road and those still to be delivered (to unaware new owners), until this serious safety issue has been resolved.
