Problems with the Electrical System
The electrical system is woven in and out of every system in the Prius. When something begins to malfunction, it creates problems that most people don’t want to deal with.
Here is an NHTSA complaint to read. “Error codes P0113 and P0102 and warning messages for Check Engine and ICS Malfunction appeared when starting the garaged vehicle in approximately 55°F room temperature. [Dealer] and Toyota’s Customer Care Telephone Center explained that they will not inspect (although under the 3-Year/36,000 Mile warranty) without a service fee. Online, reports that a failing 12V battery may cause multiple codes to be triggered were also met with a request for a $110 diagnostic fee. The battery is also under the 3-year/36,000-mile warranty.”
Aside from this electrical problem, there is also a dangerous recall issued on this model. NHTSA Campaign Number 18V579000 states that the engine wire harness may chafe and short, which can lead to a fire. This affects nearly 200,000 vehicles. If Toyota wants users to “find their element” it should start by getting the basics in check – such as having a vehicle that won’t explode into fire.
Problems with the Auto High Beam
To see clearly on the road, drivers must have superior exterior lighting, but the Prius is struggling to keep up in this department.
One NHTSA comment states, “Auto High Beam feature intermittently cuts out and then resumes, especially frequently in rainy weather. While off, I cannot engage the high beam without first shutting off the AHB feature. Many similar reports regarding Toyota vehicles.”
Of the Toyota communications, there is nothing talking about the high beam malfunctions or offering a resolution, but that seems to be the norm for this automaker. Instead, the company continues to boast about its lineup of hybrid vehicles hoping to deceive customers into believing it is the best. The original leader in any industry is often overtaken by successors who did it better. That’s where the Toyota Prius is at – it will soon be seen as the dinosaur when it becomes extinct.
Problems with the Brakes
It doesn’t matter what type of car is being discussed, the service brakes are a common system that should be perfected by now. Yet, the Prius is struggling to maintain proper stopping power.
Here is yet another NHTSA comment. “I was driving up to my garage on the side of my house on a clear day, early afternoon. I was traveling about 3 mph and tried to stop to park in front of the garage door. I depressed the brake pedal and it did not engage, but lurched forward into the garage, crashing into the garage and causing damage to both the garage and the auto.”
There’s a larger problem that is discussed throughout the manufacturer’s communications. Service Bulletin #J0R_Region Email states that the Intelligent Clearance Sonar (ICS) has faulty software programming that could activate while the Prius is in the car wash. When the ICS activates in the car wash with the vehicle in neutral, it can cause significant damage to the Prius and the car wash. Wonder if Toyota is handling the repair bills for that? For owners who want to “find your element” with the Prius, it might be best to hand wash the car instead.
Problems with the Windshield Cracking
Seeing out of the windshield is essential to on-road safety. This piece of auto-glass must be free and clear for drivers to see where they are going, but many Prius owners are facing trouble.
Take a look at this NHTSA review. “While driving on the highway in the rain at 55 mph, a very small pebble/bug struck the lower right windshield below the wiper. It was not very loud but did create a crack in the windshield within a few minutes. Within a few days, the crack has spread across the entire windshield.”
Sadly, many customers also discuss how Toyota isn’t covering this defect, leaving the responsibility of the bill in the hands of the owner. August Strindberg once said, “Sometimes not seeing things can be a blessing,” but it’s clear he didn’t mean from behind the wheel of a car. Not seeing things because of windshield defects is just a disaster waiting to happen

| Description | The automatic high beams will occasionally fail to operate and are stuck in low beams until about 2 minutes have passed, or until the automatic high beams switch is turned off to disable the system. This seems to be a software issue, as it seems to occur when an approaching vehicle passes by with bright lights. When this happens, all high beams are disabled for a couple of minutes, even if the high beam lever is switched to low beams and back to high. |

| Description | Unknown my car started stalling when it comes to a full stop. I. E. If I stop at a red light or stop sign, and I then press the gas, it stalls. It might inch forward, but it doesn't really accelerate. This happened last year, and I took it to the dealer. They couldn't reproduce the results, and they could only suggest changing my small 12v battery. Today, it stalled 8 times, between 2 short drives. Each at a stop sign only travelling ~5 miles total. I have an appointment at the dealer but this is exactly what happened last year with no diagnosis. No check engine light is on or anything. |

| Description | Certain 2018+ and all later toyota prius c modes have a 12v battery for which there is currently no oem or aftermarket replacement. The battery has a form factor (shape and size) that is exclusive to these vehicles and not used in any other car sold in north america. Vehicles with failed batteries (like mine) cannot be operated. Toyota should retrofit these cars to accommodate the battery used in early (pre-2017) model cars which is electrically identical and available as an aftermarket replacement item. |

| Description | From the first week of ownership sensors would alarm that they needed cleaning but they were clean. Parking assist sensors also malfunctioning. Also saw intelligent clearance sonar error messages and warnings. Alarm tended to go off in wet weather. Brought to dealership many times and problem occurred infrequently that no problem was ever found. For two years I was plagued by alarms of sensor malfunction. I worried the sensors would fail to detect cars and objects in front of, behind or on the side of the car. That would be a serious failure and cause of an accident. After two years of unsuccessful testing, I traded in the car. |

| Description | My windshield has cracked twice without being struck by an object and without being near another vehicle. Both incidents occurred during normal highway driving. I was not speeding or driving recklessly. Both times required the replacement of the windshield as the crack quickly spread and affected a good portion of the windshield. I am requesting reimbursement for the cost of replacing the windshield (twice). The first incident occurred just a few days after purchase. The second incident occurred today, march 4, 2021. |

| Description | On dec 2, 2020 while driving on the freeway at about 45-50 mph our sunroof exploded causing us to get to the side of the road. The shade was closed which saved us from exploding glass. There were no road hazards, no issues other than a spontaneous exploding of our sunroof. The orlando police dept was summoned and the roadrangers stopped to assist us. I took the car directly to the toyota dealership in clermont, fl and they repaired the glass at no charge but told me had the car not been under manufacturer warranty I would have been responsible for the cost of replacement. If the shade had not been closed the entire passengers within the cabin would have been splattered with shattered glass. |

| Description | While driving on rural roads with no street lights, the automatic high beam system malfunctions when passing oncoming traffic who do not dim their headlights or who have those headlights that should be illegal (like ford). Normal low-beam headlights do not cause the system to malfunction. I believe this malfunction to be related to the camera sensor located on the windshield and when the glare of the excessively bright headlights hit that sensor, it crashes the auto system. The symbol on the dash that indicates that the system is working normal cuts off for approximately 25-30 seconds, during which time the high beams will not engage. After that 30 second delay, the system reboots, the light on the dash comes back on and the high beams re-engage. This is dangerous as all manner of wildlife cross that road at night and without bright lights, my reaction time is cut in half. I have talked to the toyota dealership about this issue since I purchased this car in may of 2019 telling them there is a malfunction in the system, and was initially informed that this was normal functionality. I owned a 2017 prius prime advanced (one year older than this one) and it never malfunctioned, so I know this is a malfunction in the system. After speaking with the service manager in depth about my experience with this issue, he finally understood that this is an issue and not normal functionality. They have kept my car several times trying to recreate the failure, but unless they drive out in the middle of nowhere (super dark) and come across someone with "too-bright" headlights, it is unlikely they will accomplish a failure. I was also told that toyota did not know anything about this issue. I have since done the research and found that this has been an issue since at least 2017, and occurs on various toyota models (prius, avalon, rav4, etc...). I have video of the failure. |

| Description | Supplement to complaint # 11384074 the vehicle had the same problem on january 11 and 12, 2021 at approximately 7 am. Speed was 76 mph, and the fuel deprivation occurred for 8-10 seconds each time. The vehicle has never had the problem going home at 2 pm. |
| Category | Engine |
| Date | Dec 18, 2020 |
| State | CA |
| Description | After the hybrid battery is discharged, and the gas engine kicks in, the vehicle loses power for approximately 5-10 seconds on the freeway. This has happened four times, at approximately 7 am, on december 1, 10, 14 and 15. On all occasions, the temperature was between 40-45 degrees fahrenheit, and at highway speeds. The cruise control was not in use. No warning lights came on. I called the toyota dealer on december 1 and the service adviser said that since no warning lights came on, he could not determine the problem. I have a photo showing my contacting the toyota dealer on december 1st. On december 10, I took the vehicle into toyota in the afternoon. The dealer checked the vehicle and road tested the vehicle without having the hybrid battery charged, and the air temperature was warmer. I was charged 0 for the diagnostic service, although I have an extended warranty. The same problem occurred on december 14 and 15. Specific problem unknown but I believe that a switch that controls the gasoline volume into the engine after the hybrid battery power is depleted is defective. I was in the carpool lane at approximately 7 am on all 4 occasions and my speed dropped, although I depressed the gas pedal to maximum as well as pumping the gas pedal, all to no avail. The car is in use only monday, tuesday, wednesday and thursday, the days that I work. I contacted toyota customer advocate (800-331-4331, case # 2012120505) and they said they did not have the ability to determine if anyone else ever had the same problem. |

| Description | 'hybrid system failure' appeared on dash display during a long (120 mile) drive at highway speed on september 24. After driving about 40 miles further, the 'check engine light' came on and the display said to pull over immediately. As I pulled off the freeway, messages told me the power steering and power brakes were shutting off and left me in fear the car would die on the freeway ramp before I could pull over. Towed car to dealer who fixed a loose cable. This week (11/10) the display showed the same message. This is now a recurring problem with this model. |

| Description | Ireceived the warning that "pre-collision system malfunction" while I was driving on the highway this morning. The warning message asked me to stop the car at a safe place and visit the dealer. As soon as I got off the highway, the car stopped itself, and the steering was locked. The car was completely disabled. After turn off the car completely for a few minutes, I can restart the car with the warning message persists. While I was looking for a safe place to park the car, the car gradually stopped itself again, and the wheel steering locked itself again. The car failure and the fact that the steering wheel got locked itself put me and my passenger at great danger. |

| Description | After starting from a stop after the traffic light turned green, the car in front of me pulled ahead as they accelerated faster than me. When the car in front of me was about 50 yards in front of me, and I had reached about 25 miles per hour the car's collision avoidance system engaged and slammed on the brakes and brought me to a full stop. The car in front of me had not applied their brakes or slowed at all, and there were no visible obstacles. My car stopped so suddenly that I thought I had been hit from the rear at high speed until the red warning lights appeared on the dash (after the braking started). The cars behind me almost ran into me because of the sudden stop. |

| Description | The car is inadequate in the winter. When it snows I can't keep the windows clean. They changed the fittings and I can't even put winter blades on the car. Also, and this applies to almost all new cars as well, the led lights freeze over. It's a safety hazard not to have lights that work. And it's a safety hazard to have to get out of the car in dangerous conditions to try and scrape ice off the windows and lights. The front and rear lights get caked with ice and snow. This picture is of my windshield after an hour of warming up. The wipers stay caked with ice. And when I turn them on, this is what happens. They smear the windshield with ice. They smear it with water too. I can't squeegee water with ice. I'd love to trade it in, but everyone has led lights. They're a safety hazard. And these issues are keeping me from buying a new car. I would appreciate it if you addressed these issues. The car companies won't listen to me. Thank you have a great day |

| Description | Automatic high beams dim and then fail to brighten intermittently. When driving, automatic high beams function as intended then the dash indicator spontaneously turns off and the headlights fail to brighten. Vehicle has been to the dealership service department twice for this. The second time , the dealer was able to duplicate the problem both in my vehicle and in a 2019 prius from the inventory. Toyota technical assistance is adamant that the problem is normal functionality. I fail to understand how the high beams not brightening when they should during night driving is normal functionality. |

| Description | The heat shield on the underside of the car, by the storage battery came lose while driving and was damaged. It is held in place by only four plastic pins. The car is so low to the ground that it is hard to clear normal speed bumps let alone older larger ones. We were traveling a housing addition less than 20 mph and just went over an older high speed-bump and puddle when it occurred. We drove the last 100 or so feet home and wired it up out of the way so the car could be driven at low speed too the dealership. The dealership told us this was damage due to our driving negligence ie: "we hit something". When this shield comes off it falls straight into the vehicle exhaust pipe and ground, there is no simple way to remove the piece until a full repair can be completed. It must be wired up off the ground or part of the wheel and exhaust must be disconnected. It took the dealership three tries and over a month to get the correct shield in and perform the repair. The part number in the toyota parts specification and the repair parts warehouse or not the same. |

| Description | I started my car, put it in drive and began to make a u turn out of a parking lot when it suddenly accelerated on its own. I had three turns I had to make in quick succession (u turn, left on public driveway, right on main road) to get on to the main road, and I did this at break neck speed. By the second turn I was giving all my strength to trying to get the brake to work, unsuccessfully (locked), and was fully focussed on turning the car safely to save my life at such high speed. My tires squealed on the third turn and my cell phone flew through the air. I could not make a tight right turn so made my turn in to the left lane (proud of my driving success given the speed). Once I navigated the turns the car slowed down and brakes worked as normal. This all happened in around 20 seconds I'd guess, and less than 1/4 mile I think. Just fortunate there were no cars coming in either direction. I am alive to tell this story. I had the car towed to a dealer and am awaiting to hear what the have to say. I am petrified at the thought of getting back in to that car. |

| Description | I owned a 2008 prius with 273,453 miles when I traded it for a 2018 prius on 3/15/18. My 2008 never had the windshield replaced; meanwhile, the 2018 has been replaced once and the 2nd is now cracked within 2 months of replacement. On 8/7/18 I was driving in a single lane road with no vehicles ahead or in the oncoming direction when I heard a pop. Within 5 minutes a crack began at the base of the windshield and extended about 9' upwards and towards the passenger side by the end of the day. Next morning the crack was 17' long, and by the 3rd day the crack was 26'. After that the crack seems to stabilize. On 10/9/18 I was driving on I-95n heard another pop and a 2nd crack began to form. There were no vehicles in front of me when I heard a pop. An additional crack started that curved from the driver side and extended 14' from the base of the windshield 3' from the old crack towards the driver side. The 2nd crack affected my vision so I had have it replaced immediately. On 11/2/18 I had the oem windshield replaced for 0 (deductible) plus 7 (toyota camera recalibration). On 12/19/18 I heard a pop while at a stop sign and the new windshield developed a crack from the base of the glass extending upwards 4' then curved towards the passenger side for another 7. 5' by the end of the day. The next day the crack curved up and to the right side for another 7. 25'. By the 3rd day, it grew another 12' upwards. On 1/29/19 a second crack formed near the initial crack at 3' higher from the base. This crack extended for 12' towards the driver side. So now I am faced with replacing the windshield again; incurring the costs and inconvenience. Given the fact there were no vehicle around when the cracks have repeated appeared I feel that this is a manufacturers defect and not a factor of my driving. |

| Description | New car just over 1000 miles. Rear tire blows on freeway, no pothole or anything hit. Since owning the car I've heard a faint thudding when going over 65 miles an hour. No indicator light and the tires felt hard, not deflated when I checked. So I thought it might just be an uneven road making that sound. Now I believe it was the tire. I have tons of photos if needed. I fishtailed on the freeway and was close enough to an exit that I got off on it. Luckily did not cause an accident. |

| Description | Last year,june 2017, while the car was parked we noticed there was a hairline crack on the windshield. We received some quotes saying it would be about 0 to fix. So we decided to go with an adhesive injection and paid about for someone to come fix it. However, after a month, it spread. We had no choice but to replace the windshield. Last month, same thing happened. Car was parked, nothing hit it. Same hairline crack. I haven't fixed it because of the heavy expense. But it has spread. Checked online to see if anyone else has the same issue and found there's a class action lawsuit for this but it's for 2014-2016 toyota prius. Apparently they have not fixed this problem for the 2017 prius. Also, there's a recall for my car for another issue. |

| Description | This is a brand new car I purchased. There is a high-pitched noise that the brake pedal makes when you depress the brake pedal. I thought this was part of the beeps the car makes, but it's not. The brake booster was replaced, but the brake pedal continues to make a high-pitched chirping noise. I returned to toyota service to have it checked out, but they said that this is a normal sound that other priuses make. This concerns me that the brakes are defective since I've never heard of brakes that sound like this. |

This creates driver distraction. The problem is more-so with apple ios rather than the prius in particular. |

| Description | The gear would shift either from 'drive to neutral' or 'reverse to neutral' this happened more than 10 times when I had my sister, mother, and father in the car. 1) it happened when I was pulling out of the garage (about 20 degree angel) going up the hill. I went to pick them up, all 3 pf them went in. I had my foot on the brake and gear on drive, when I let go of the brake the gear shifted automatically on neutral. After, 3 tries, the car finally was able to go forward without struggle. 2) I was trying to back in one of the spot (flat ground), foot on the brake, gear on reversed. When I let go of the brake the gear shifted to neutral automatically. I struggled for 3-4 times before the was able to hold on reversed and park the car safely. 3) when I was in the middle of the intersection (flat ground). I had my foot on the brake, when I finally was able to make a turn, my foot on the foot and gear on drive, when I let go of the brake the gear shifted to neutral of the the sudden, I had to try 3-4 times before it was able to move forward without a struggle 5) I was on a hill (about 20-30 degree angle) facing up. My foot was on the brake and gear on drive, when I let go of the brake the gear was shifted to neutral. I struggled for 5-10 minutes (going from drive to neutral back in forth) as my car was not able to hold drive mode, I eventually asked my family to get out of the car as I was getting worried and frustrated, my family was out of the car but I was still struggling, in the process I hit a car behind me. 6) I was finally able to park the car in with any passengers and somewhere flat ground. I left my car for 30 minutes and came to drive my car. I started my car, I had my foot on the brake and gear on drive. I let go of the brake then my gear shifted to neutral again, I struggled for 3-4 times before the car was able to hold on drive |

| Description | Driving 60 mph on interstate a piece of debris hit my windshield. The piece was so small I didn't even see it hit the windshield. The piece did pretty significant damage to the windshield and it spidered out in all different directions, larger than a quarter. My concern is that I have been in other vehicles and had debris hit the windshield the same situation that is larger and just barley put a nick in the windshield. Ive read on complaints about 16' and 17' models having this issue as well and it doesn't seem like toyota is addressing the issue. I am worried about the structural integrity of my windshield. |
