When it comes to finding a pickup truck, many consumers flock to the 2021 Chevrolet Silverado 1500. Maybe it’s because the company claims it is the “strongest, most advanced,” or maybe it’s just because there aren’t a lot of options on the market. Either way, the Chevy Silverado 1500 is a disappointment in many people’s eyes. With complaints about the electrical system, structure, engine, powertrain and suspension, there’s so much that could go wrong behind the wheel of this truck.

Problems with the Electrical System

With all the Chevy Silverado 1500 has to accomplish, an advanced electrical system is a must. However, customers are positive that this technology isn’t what it should be.

Here’s one example from an Edmunds review. “I have a 2021 Chevrolet Silverado and I have been to the dealership 3 times with issues with my check engine light coming on with less than 3000 miles on the truck. Each time I go it’s the same code. They tell me we could not find any issues so we just reset the light. I am sick of this truck I will be going back to the dealership in the morning due to the fact my check engine light is back on for the 4th time in less than 3 months.”

It seems nothing much has changed from previous models. In fact, the electrical systems were so poor on 2019 and 2020 trucks that class-action lawsuits were filed against GM. The 7-inch in-dash infotainment systems have been a major source of complaints, and it looks like the 2021 models will continue down the same path. It seems that GM doesn’t learn, no matter how many times the company’s wrists are slapped.

Here is an actual complaint logged with the NHTSA regarding 2021 Chevrolet Silverado Electrical System Problems:

THIS 2021 SILVERADO HAND A COMPLETE ELECTICAL FAULURE LEAVING THE VEHICLE DEAD IN THE IN THE ROAD AT NIGHT. WE HAD NO POWER AT ALL, NO WARNING FLASHERS IN THE DARK AT 9:00 PM AT NIGHT. WE WERE ALMOST HIT BY A CAR COMING AROUND CONER AS WE BROKE DOWN AT THE INTERSECTION WERE NO STREET LIGHTS WERE. THIS TRUCK HAS LESS THAN 500 MILES ON IT AND HAS ALREADY HAD THE FULL ENGINE REPLACED, PROBLEMS WITH THE INFOTANMENT SYSTEM AND NOW A COMPLETE ELECTRICAL SHUTDOWN. WE WERE UNABLE TO GET THE VEHICLE TO DO ANYTHING AND WAITED FOR TWO HOURS IN THE ROAD FOR A WREAKER TO ARRIVE.

Problems with the Engine

When the time comes to tow or haul, it’s important to know that the truck can handle it. Without a solid engine, the journey becomes anything but enjoyable.

Yet, that’s what customers are talking about, such as in this Edmunds review. “Have a new 2021 Silverado and engine stared with a ticking sound then went to a knocking sound then every light on the dash came on Check engine traction control brakes transmission everything so we brought it to the dealer they said it was a bad lifter her car is been there for five weeks now I know there’s more issues with the car than that lifter the sound of the engine was so bad.”

GM is fully aware that there are engine problems. The automaker even issued Service Bulletin #PIP5776C, which discusses a misfiring condition caused by lifters that come apart. To fix the problem, the four lifters and the lifter guide must all be replaced. This shouldn’t be occurring on newer trucks, especially at this price point. Without a functioning engine, the Silverado 1500 is nothing more than a glorified wheelbarrow.

Here is an actual complaint logged with the NHTSA regarding 2021 Chevrolet Silverado Engine Problems:

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated while driving at various speeds, the vehicle would not accelerate when the accelerator pedal was depressed. The contact also stated that a loud knocking sound was coming from the bottom of the vehicle while reversing. The contact stated that the check engine warning light was illuminated. The vehicle was taken to a local dealer where it was diagnosed with the timing belt needing to be replaced. The vehicle was repaired however, the failure recurred. The manufacturer had not been informed of the failure. The failure mileage was approximately 2,500.

Problems with the Powertrain

The powertrain is another system that works in conjunction with the engine to provide moving force to the truck. However, it’s also another critical area that is causing complaints.

Here’s one more Edmunds review worth mentioning. “Started noticing an intermittent vibration/shutter at about 4,000 miles when gently giving it gas. It has about 9,000 miles on it now and does it all the time. It’s a 2.7l 4cyl. Has been to 3 dealers, 1 dealer twice. They magically say there’s nothing wrong with it. One dealer did say yea I noticed it but, that’s because it’s a 4cyl.  Every person that rides in it asks me why it’s doing that. I feel like I’m being lied to by the dealers just so they don’t have to fix it. I absolutely hate driving this truck!”

Again, issues are being dealt with by GM, but not in the way owners wish. Service Bulletin #PIP5794A discusses the shudder that is occurring with the truck. However, GM states it is just coming from the camshaft actuator system and is “mistaken for a transmission issue.” Basically, the automaker is saying, “nothing to see here.”

Problems with the Structure

When it comes to getting heavy jobs done, the truck must be well-built to accommodate the added weight. However, everything about this Chevy pickup shows it wasn’t put together well.

One NHTSA complaint states, “The contact owns a 2021 Chevrolet Silverado 1500. The contact stated while in the vehicle, the contact had dropped his bank card in between their seat and center console. When they reached for the card, they felt a sharp object in between the seat and the center console which caused the contact to cut their right hand which caused the contact to receive 7 stitches. Medical attention was needed for the injury.”

It turns out that this isn’t the only seat-related issue. NHTSA Campaign Number 20V792000 talks about a recall where over 600,000 vehicles may have unsecured seat belt brackets that fail to restrain occupants. Shortly after that recall was issued, NHTSA Campaign Number 20V811000 was also released saying that affected vehicles include the wrong bolts in the seat belt fastening location, also making it more challenging to restrain passengers. To further prove how defective this truck is, just take a look at NHTSA Campaign Number 20V684000. This recall points to the overcuring of tires used on the Silverado, leading to tread and belt loss. Basically, there’s no part of this truck that can be relied upon. Maybe it’s time for the company to get back to what made it “like a rock.” Those were the good old days when trucks meant business.

Problems with the Suspension

When it comes to creating a smooth ride, the suspension system needs to be top-notch. Yet, this is another area where the Silverado trucks lack.

Read this NHTSA review, “The antilock brake system (ABS), brakes and electronic stability control system (ESC) might not illuminate. This could cause the driver to not know if any of these systems are inoperable.”

With previous Silverado models, class-action lawsuits were filed regarding the handling of the trucks. Many customers found that the vehicles would vibrate and shake when hitting higher speeds, such as those occurring on the highway. It became such a prevalent occurrence that the condition was named the “Chevy Shake.” Based on what is seen so far, the 2021 Silverado will be following suit and shaking all the way to more lawsuits.

So I have been having issues with my truck losing oil. My dealership told me that walmart made an issue with the oil filter causing it to leak oil out. After the dealership corrected the issue. I was on my way to the store this morning it was damp so I was having a lot of traction issues. Got to the gas station checked tires, no issue with them. Temperature is above freezing. Just thought maybe it's in my head. Well I get about 2 miles from my house and low oil light comes on again. So this is an issue. It has happened 2 times to me. Had I not been cautious I could have slipped off the road or had a collision because the oil mixing with the water on the roadways. I will be reaching out to my dealership tomorrow to try and get them to correct this issue again. Seems there is a service bulletin on how to tighten the oil filter. Because of oil leaks.

On 12/26/22 my wife noticed a noise coming from the engine of the pick up truck. On 12/27/22 I started the truck and noticed a noise coming from the engine. I lifted the hood to try and locate where the noise was coming from but I could not see anything. There were no lights on the dash. I drove to work and parked it. 8 hours later I started the truck back up and the noise was still there. I began driving home and the truck made a spurted noise causing me to jerk the wheel nearly driving off the roadway. The truck is still making the noise. I contacted the chevy dealer and they explained they would take a look into the issue. I've done some research and noticed that a bunch of 2020-2022 silverado's have been having lifter issues. I've also seen that the dealers are only replacing one side of the lifter banks and the others are failing 500-2000 miles after the repairs. I've also seen that people's trucks have failed on highways and streets causing accidents and or traffic hazards. This is something chevy needs to look into and fix to prevent any serious injury or death created by these issues. I don't have photos but I do have a video of the noise that I could email if need be since I can not attach the video to this form.

Anytime the weather gets colder than 32degrees fahrenheit the def system freezes, which even if the tank is full makes the truck go into limp mode until it thaws out. The engine light pops on and off with no codes associated with it. Now the breaks and break lines are freezing when it gets below freezing. These are just a few of the reoccurring problems we've experienced since buying the truck less than a year ago.

Vehicle will not start and cranks until starter kicks out, about 30 seconds each time. I am afraid if this happens at a traffic signal or stop sign it could be bad. I took it to the dealer on july 30-2022. (2972 mileage) and they could not verify concern. I found a safety bulletin on a gm website for a extended crank/ no start. It is pip5806d, the dealer says they know nothing about this. It lists a labor operation number 4088148, due to a corrupt signal from camshaft position sensor to the ecm. It has happened now 4 times, and current mileage is 6973. I have been dealing with champion chevrolet in reno nv. It has started after 8 to 10 crank time outs and the battery starts slowing the crank speed down, but around 10 to 15 minutes have passed by then.

The part was on backorder for over a month and a half. After this long wait of not being able to drive the truck, the dealership finally put a new oil cooler in. The problem persists and they are not able to figure out from the engineer what will solve the problem. I have been out of a truck for over a month and a half now with no hopes of the issue being resolved.

Truck caught on fire while driving down i75 interstate in florida. No component or system failure lights where present. Smoke was smelled by the passengers and within seconds the truck was on fire. The safety of the passengers was at full risk, and lucky to be alive! The truck was full engaged as soon as the truck pulled over on the side of the interstate. Investigation by gm & insurance company took place. The truck is available for further investigation. We are unsure how the fire started. It did come up from both sides of the cab, and very quickly. Nothing has been confirmed by any inspections completed by gm & progressive. Gm & the service dealer are not engaging as they should be.

2021 silverado rst, 5. 3. Started having strange loud random clicking sounds when first starting. Would loose power, at take off or when trying to accelerate. This was at 9400 miles on the vehicle. Was not showing any check engine light or issues on dash. When examining engine compartment, found loose bolts, that had broken. Took it to local chevy dealership, acted like there was nothing wrong with it. Instantly trying to get out of performing work. I had a feel it was going to be lifter issues. Found out while there around 4 thousand miles it already had lifters replaced. After debating with them for two days, and trying to convince them there was issues. They finally found multiple problems with lifters, misfiring, rocker arm not moving due to collapsed lifter. They found broken bolts in cylinder heads. Ended up having to replace all left and right side lifters.

I was not personally at risk during my incident, but I can see how I could have been if my situation was a different. My 2021chevy truck suddenly lost engine power at a traffic stoplight. It almost stalled coming to a stop. Then when trying to accelerate, it had very low power, and was stumbling. I was only a mile from home, and not busy traffic, so I managed to make it home. Driving very slowly with the engine clearly under very low power. No cel or warning lights came on. After getting it towed to the dealer the next day, the dealer informed me it was a failed lifter and bent pushrod. After a little google searching, I found it is a common failure in newer gm v8s. I also learned my truck was built in a date window that gm issued a service bulletin for lifter failures. According to forums and facebook pages, many other owners have had the same problem. Even 2-3 time failures with some owners. Even after repairs. Either in the date range of the bulletin or outside of it. My specific situation wasn't dangerous, but I could see how it could be, if I were on a busy highway, or if the truck completely lost power. As far as I see, no recall has been issued, just many internal service bulletins over several years. And even a class action lawsuit in regards to lifter failure. My truck was fixed with all lifters replaced with an updated part number. 5000 miles since the repair. Gm did a good job with the repair, and after some communication with gm customer service, they replaced all the lifters, and not just the broken one. This gave me a bit more peace of mind, but I worry with so many failures posted online daily, and without a documented case on nhtsa this will continue. Thanks

Vehicle began having issues at 3 months old... Random service messages, defective headlight, wierd engine noises at startup and stalling upon acceleration/deceleration. I took it to the dealer several times about the issues I were having but they always say they aren't able to replicate any issues. 3 months later I was driving on the highway and the engine started knocking. Had it towed to the dealer and it took them 6 months to replace engine, tcm, starter, and other parts. After finally getting the truck back, it was still stalling and there was a check engine light... Dealer did not reassemble the vehicle properly and several parts and bolts were still missing. It went right back in the shop and catalytic converters were replaced. I also mentioned missing parts and bolts. I get the truck back again and it still seems like it wants to stall. I was turning into a parking lot a few days later and it seemed like it wanted to cut off. While I was distracted trying to see if the truck cut off, I hit a small pole... Truck was damaged way more than it should have been because the dealer did not reassemble it properly. Body shop said my bumper was only held on by 2 bolts and several other bolts and pieces were missing. They said if my bumper was attached properly the damage would not have been as bad. The vehicle was already unsafe because of stalling and the dealer made it structurally unsafe as well... I have opened cases with gm and they aren't doing anything about it. Here this truck is 14 months old and it's been in their possession more than mine... I have asked them about replacing the vehicle and they insist on fixing the issues but never do and I end up driving an u safe vehicle around.

Speed limit 70mph and driving on the highway, suddenly the vehicle began to shake and the engine light came on and the vehicle was making a forced deceleration to 40mph. Other vehicles had to swerve to avoid my vehicle, as I was attempting to pull off the highway safely. "service brake system" alarm also came on. The manual advised when getting this alarm to have the vehicle towed. Once at the dealership this note was on my service papers " customer stated engine light was on and truck running rough and shaking, review of dtc's showed cylinder misfire on #3, tested showed possible issue with spark plug. Relocated coil to different cylinder to see if issue followed. Misfire still noted on cylinder 3, replaced spark plug and conducted test drive and note misfire still present on #3. Removed valve cover and noted failed lifter on intake valve for cylinder #3. All lifters replaced on left side of engine." the dealership stated that "this is a known problem for the 5. 3l v8ecotec engine, that the lifters fail." I am a female, I was traveling alone and had to find tow service and pay up front. Once transported 20miles to the nearest dealership, on a saturday afternoon, I was stranded at a hotel for 2 days waiting for the dealership to open and check out the vehicle. If this is a "known" problem with this engine, they should be recalled. Now I get to worry when the other side of the engine's lifters will 'fail' so they can be replaced under warranty. This is unacceptable in an almost new 2021 truck with 20,000 miles on it.

Truck started having a rough idle and was popping and banging while driving. It was hesitating while driving in traffic and would slowdown and jerk while trying to drive to the dealership. It stalled at red lights multiple times. Once it got to a dealership and they identified it as #4 cylinder lifter was malfunctioning. They have not yet disassembled the engine yet to find out the extent of the damage. This is a known issue with these trucks and gm won't issue a recall to proactively fix the issue before more damage is done to the motor. Some of which may not show up until after the warranty expires. There was no warning light or check engine light on at anytime. The dealership service department was very surprised by this. Now I'm without my truck for at least 2 weeks with no loaner of voucher for a rental. The truck has less than 19,000 miles on it and has had all regular maintenance done at a dealership.

No start issue. Intermittent no start increased in it's frequency until it wouldn't back in july 2021, it had approx. 9600 miles on it. Had it towed to dealership. They could not recreate problem. I raised hell, and started reading that others had similar problem. A tsb came out that advised tech to install . 5 shim. That seemed to have worked until recently late may 2022, have appt. With dealership again. They didn't do a scan the next day to pull a code since one might have shown up at that point. Most likely nothing there now. Truck has been driven an additional 10k miles since initial problem and now shows 21400 miles. I can't have this problem every 10k, since soon this will be coming out of my pocket. And it needs a fix as others are having the same problem. Gm has had well over a year to sort this out so I'm hoping if it isn't the cam sensor it's something else fairly straight forward. Heading in for service again on 6/15/2022 for same complaint.

I was driving and noticed several loud clunking noises coming from the engine bay. The truck began to cut out, shake, and misfire. My dash began to flash and state I had a parking brake failure. I had no choice but to be towed. I have just shy of 17,000 miles. The dealership stated I had two lifter and 1 rod failure. They replaced the rod and all lifters on one side of the engine. I took the truck home for one night and it broke down again. The dealership stated it was fixed for a second time. When I picked it up again, I made it 1 mile down the road before the truck had the exact same symptoms with shuddering and misfiring. It is at the dealership for a third time. I was surprised to fin several class action lawsuits now filed against gm concerning the lifter issue. Youtube is full of lifter issue videos. This should be fully investigated and obviously warrants a recall for lifters, rods, and the camshaft.

When I start my chevy silverado 1500, three warning lights come on that are telling me that I have brake system failure 43 mph top speed, service esc and service trailer brake system. When I drive, the brakes are very mushy and the truck is very difficult to brake. 20 minutes later after stopping and getting ready to take the truck to the dealer, the brakes worked fine. The dealer couldn't replicate the problem at first, but finally had the issue when they were putting it on the rack to perform improve my tire alignment, so they said they updated the software. The truck brakes worked fine when I left the dealership. The next day (saturday) I went to start the truck and the same issue happened. I can't take it in as service is not available on saturdays so I started looking online. Apparently there are several other owners dealing with this same issue and have been for years. I have read that it might be a variety of things causing this issue, but someone needs to get this resolved asap as I have read about some getting into accidents regarding this.

My 2021 chevrolet silverado started on fire and blew up in my driveway. I had just returned from the store, parked it and went inside. No more than 3 minutes later, my neighbor came running over to tell me my truck was on fire. There were no issues at all while I was driving the vehicle. The township fire department said this is the 4th 2021 chevrolet silverado that has burst into flames in the last 6 weeks. They said they all had the 2. 7l turbo engine, as well. The truck is a complete loss. I have contacted the dealership and chevrolet about the issue and have not heard back yet. The fire started in the engine compartment and quickly raged out of control. The hood and engine disintegrated from the heat. The vehicle was towed away and the insurance adjuster has yet to go out and look at it. If I would've been stuck in traffic on the way home, I would have been in the vehicle and may not be here typing this report right now. It went up that fast. This is a major safety issue that needs to be thoroughly investigated before somebody loses their life. It nearly caught my house on fire, but thankfully there was only minor damage to some garage trim and the driveway is ruined. Please investigate this issue immediately. This was a pretty traumatic experience, to say the least.

A squirrel chewed into the fuel line [hose - gm (84871298), see: https://www. Gmpartsdirect. Com/oem-parts/gm-hose-84871298). This caused a fuel leak that could be directly observed only while the vehicle was running. On one occasion, however, a small pool of fuel appeared under the vehicle immediately after shut off. This part failure poses a fire and explosion risk. In addition, the wasted gasoline pollutes the atmosphere. The line was replaced at lynn layton chevrolet of decatur alabama (invoice 608119). The part was inspected by lynn layton chevrolet as part of that service ticket in order to determine the cause of the leak. To my knowledge, further inspection has not occurred. No warning lamps indicated the failure. The problem was detected by observing the trail of fuel when parking.

While driving east on I-24 with my granddaughter. I felt a thump much like hitting a big dog or something in the road. I looked at my 10 year old granddaughter, she was looking at me, she said what was that? I said I don't know, but it happened again in about 1/4 mile down the road. We traveled about another 1/4 mile when the truck started sounding like a machine gun being fired!! My granddaughter started crying as she was scared, I pulled over into the emergency pull off to check my truck. It was running good now and no engine light was on. So I continued driving toward clarksville, tn. Although I considered turning back and heading home. I thought maybe it was water in the gas or something. After arriving in clarksville to pick up my two grandsons we started home. As soon as I got on I-24 west the truck started the same thing again. Felt like we hit a big dog and then started sounding like a machine gun being fired. This time the engine light did come on. I was afraid the truck was going to quit running and there I was with 3 grandkids on a very busy I-24!! I contacted patroit chevrolet where I purchased the truck at. They told me it would be 6 weeks before they could look at my truck!!!! I hung up but called back as I was afraid that I couldn't make it home, the truck was running bad!! They found that it had dropped a lifter, it had only about 6,300 miles on it!!! They had it for about 3 weeks. Now, I find out that gm has had a lot of problems with these motors, "a lot of problems"!! I,m sure the problem will happen again, I am hoping no one gets killed when it does. This is a dangerous problem!!! Gm needs to replace these motors or buy them back or something!!!

On top of all of that they don't have a replacement part for the truck. Now the truck is going to sit at the dealer for one to two months. I am now paying on a truck that I can't drive to work and no loaners available. My question is why are they aloud to still put these parts in a truck.

My vehicle lost power to accelerate on an on ramp just before a bridge over the wisconsin river and I was not able to merge into traffic. I was nearly put into the guardrail just before the bridge and I had to wait for the semis and other vehicles to pass and give me an opening. I drove straight to the closest gm dealership under reduced power. I was accelerating and would have been able to easily merge until suddenly my engine seemed to stall/lose power significantly. This caused me to slow down and not be able to get over as there were two semi trucks in the northbound lane of highway 39 in kronenwetter wi. I have now found out that the power failure is due to something that is, according to my rough calculations happening very frequently to my model of truck for the years 2019, 2020 and 2021. I am curious to know how many trucks per year? One dealership told me they do about 2 trucks per week in wausau and a dealership in green bay wi told me 3 per week. Rough math tells me that spanning 4500 certified gm service centers equals over 400000 vehicles per year. When does this become a safety recall if not a general recall to protect consumers? Gm knows about this problem however they continue to put in the same faulty lifters in the vehicles and only fix/ put in upgraded lifters when they break. How can a car manufacturer put vehicles on the road and sell them knowing there is a potential no only to break but in instances like mine or others I can't even envision, cause an accident or worse?

Approx every 1,500 miles engine will crank for ~25 seconds and not start. This creates two safety problems 1) defective part in engine could cause metal shavings in engine or some other form of part failure resulting in seized engine along with fire or accident. 2) vehicle has start stop feature. Failure of vehicle to start at an intersection could result in a traffic accident. Vehicle was serviced at chevrolet dealer where they stated vehicle could not be repaired without demonstration of the problem. Dealer did not inform me about, inspect or make repairs for two service bulletins that I found on the internet for the issue. One service bulletin is for a defective engine part. The camshaft target wheel could be bent and contacting the timing chain. The other dealer service bulletin is for a software update to correct a similar starting issue. For review, I uploaded the dealer service report along with both dealer service bulletins. I'd really like nhtsa to look into why gm is not informing vehicle owners about the software issue or the known defective engine part.

Well 10/25/21 my wife & I were driving when we heard a loud banging noise coming from truck we also lost power & truck was shaking bad . Called dealership asap was told bring in now .

So basically a catastrophically engine failure on a brand new 2021 chevrolet truck with 7000 miles . Had this happened on the highway @ highway speeds with sudden lost of power this could lead too an accident & possibly a loss of life . The sad part is this has been a ongoing issue with the 5. 3 & 6. 2 engines since 2018 & chevrolet is aware of it. They have no fix and are installing the same defective parts back only too have same issues again & again. Spoke with corprate & they have no answers or cares my wife said she would never drive truck again especially since admission from a chevrolet service tech said it will happen again.

The contact owns a 2021 chevrolet silverado 1500. The contact stated that while driving at 50 mph, the brake pedal was depressed as he began to approach traffic on the highway. As the contact began to steer the vehicle to the left, the entire front driver side wheel assembly detached from the vehicle without warning. Once the vehicle hit the ground, the driver and passenger-side air bags deployed and the contact hit the vehicle in front of him as he lost control of the vehicle. The contact was able to steer the vehicle off the highway and onto the left shoulder, the side curtain airbags then deployed as the vehicle came to a complete stop. Due to the failure, the brake line broke and spewed brake fluid throughout the engine and onto the road which resulted in an engine fire. The authorities were called to the scene and were able to extinguish the fire. A police report was filed. The contact did not seek medical attention at the scene but did treat himself for a scrape to the head once he returned home. The vehicle was towed to his home where it remained in his possession. The dealer was notified of the failure and he sent them pictures of the damaged vehicle. The manufacturer had yet to be notified of the failure. The vehicle had yet to be repaired.

Driving the vehicle on october 10, 2021, with my fiancee and her mother in the vehicle. Upon exiting expressway I-75 a noise in the front end could be heard. It was a pinging/clinking noise that didn't change in frequency under braking nor under speed changes. It stayed at the same frequency of occurrence regardless of speed but wasn't present at vehicle stop or idle. It seems only to happen when vehicle is in motion. The noise became louder at lower speeds of driving. Vehicle was taken to a gm dealership on october 11, 2021, for repair. The dealer indicated that they could not repair the vehicle as gm issued a work instruction (pip5653) stating no repair or resolution is available. Gm indicates there is no problem to the vehicle however something is wrong with the front end axle and if it breaks then there is risk of accident as the wheel could lock up causing loss of control and/or loss of steering. Upon reading document pip5653 I learned that all gm full size pick-up trucks and suvs from model year 2019 to 2021 are effected. This is a huge population at risk for possible loss of control and/or loss of steering to be supported by simple gm comment. There must be a fix.

On july 27, I encountered a failure of the rear vision display system on a 2021 chevrolet silverado. In short, the system used to display the rearview image went blank, and remained blank, the moment I first shifted the vehicle into reverse. Hence, no rearview image was visible while I was in the process of backing up the vehicle. I believe this may be a noncompliance with fmvss 111 or a closely related safety defect (I worked in safety engineering at general motors and ford for a combined total of more than 30 years). I made a video to document this failure, and I uploaded it to youtube. It is available at the following url: https://youtu. Be/zhbzwteacbg this vehicle was provided to me as a loaner vehicle while my personal vehicle was being repaired by quality chevrolet in escondido, california. Shortly after leaving the dealership, I pulled over to the side of the road and paired my cell phone with the vehicle. It took several attempts to successfully accomplish this. I then made a hands-free call and then proceeded to drive home. Within a couple miles, I decided to make a u-turn. Given the size of this vehicle, completing this u-turn required backing up. The moment I placed the transmission in reverse, the center display went blank and consequently no rearview image was displayed. Even after I shifted the transmission back to drive, the center screen (which is also used to display other things like the radio station, time, temperature, etc.) continued to remain blank. However, the audio continued to function (noted at 1 minute and 15 seconds into the video). I decided to make a video to document the condition prior to turning off the ignition as my experience has been that such malfunctions are likely associated with software errors that can be difficult to track down and replicate. I drove this loaner vehicle several other times before returning it to the dealer. On each occasion, the rearview image displayed when the vehicle was put in reverse.

Vehicle door locks. The key from my 2016 chevy will open my 2021 chevy. It does not seem safe when you assume locking your doors would prevent someone from gaining access to your vehicle. How often do you go shopping, put your purchases in the vehicle and shop some more not knowing that someone can just unlock the doors and steal your valuables or wait in the backseat for you to return and harm you. What are the odds that I have a key from an older vehicle that unlocks my new truck doors and also how many other keys are out there that will do the same thing. At the very least gm should at least warn a buyer that just because you lock your doors that doesn't really mean anything. I am sure alot of people are not aware of this lack of safety. We have safety labels on cigarettes, liquor, guns drugs and so many other things but nothing about locking your car doors doesn't mean they are actually locked. I contacted the dealership where I bought it and they claimed they were not even aware of that until they checked further. Changing the locks will not help so it seems like there should be some option. Insurance companies won't want to pay for any theft.

It got towed to the dealership he bought it from. They replaced the brake system control module and said it's good to go. Maybe it is, maybe it's not. There have already been 2 recalls pertaining to this exact issue released, none of which applied to his truck according to the vin recall checker on gm's website. If the problem has been figured out and fixed, then it wouldn't still be occuring. This is a major safety concern, one that I feel people need to be aware of. Which is why I'm sharing what happened to my friend's truck on behalf of him. This situation is exactly why the emergency brake on vehicles is an all mechanical system that allows the driver to quickly and directly be able to apply the vehicles brakes. It's a reliable and dependable system that's been implemented for over a century. This is a prime example of why vehicles still need to have one onboard. This vehicle doesn't have a real emergency brake. There was an emergency in which the vehicles primary brakes failed and weren't able to slow down the vehicle. The little "emergency brake" button was more worthless than the main brakes that failed to do their job on this truck with less than 5,000 miles on it because the emergency brake system on this truck has worked 0% of the time it was needed so far. This isn't some engine misfire, sunvisor defect, or bluetooth pairing problem, this is an out of nowhere total brake system failure. This is not good. And people need to be made aware that the problem is still occurring, and on vehicle's that gm isn't aware that it may be applicable to according to the absence of any recalls per vin.

The lifters in the truck are failing, a brand new truck 12,000 miles on it and the lifters have failed. Which is also leading to an oil problem. They are trying to only fox one bank of lifters instead of replacing both. Due to them wanting to wait until the fail. They have known about the problem and I bought the truck from them not knowing that the engine was a faulty engine. When you pay 70,000k for a truck you are expecting it to last a lot more than 6 months. Which is also causing the bent pushrods on the truck. I bought the truck brand new at the end of january, for the lifters to fail, valve springs, and for bent pushrods, I'm estimated to be out of my truck for the next 3/4 weeks which would bring it close to lemon law

Faulty lifters causing the truck to throw piston rods. This causes malfunction of the traction control, parking brake, transmission,auto locking rear differential. I have had my truck in the shop 3 times for the same issue all within the 1st 10,000 miles. This particular motor has been taken out of production. Upon speaking to mechanic managers at multiple gm dealerships they were not surprised and personally gave me advice on the lemon law. My truck, which is my 1st brand new vehicle, has been out of service now for a total of 45days. I have still made payments up to date. The dealership offers a car or small suv while repairs are being completed, not a truck! Beware of the 5. 3litre ecotec3 v8 motor.

Upon returning home after a short drive I pulled into my garage and almost drove through the wall… I purchased parking assistance and it was not provided. The feature apparently failed and turned off at some point without clearly notifying the driver. I don't know if it provided a silent notice that automatically dismissed but it certainly did not notify me when I really needed it… low speed. The park assist light is indeed off now when the vehicle starts. Clicking the button reports “park assist off” even though it already appears off and is certainly not providing the intended safety feature. Clicking the button again does not turn the light back on but if clicked again it will again report it was disabled. This is strange and confusing for the driver. Using the infotainment screen one can toggle “park assist” off and the drivers info screen by the speedometer will finally say “park assist off”. Turning the feature back on in the infotainment screen actually turns the park assist button back on for about 5 seconds then it silently turns off and the driver is not warned that the system is not working. The driver is not properly warned of feature failure even though it appears the software knows it is not working. The little button goes out but the driver message screen does not warn the driver. This failure and poor awareness is a safety risk. Yes, we are unlikely to be parking super close to someone but we might indeed park near a gas hot water heater or similar hazard in work trucks. The driver must know if safety features failure during driving. Otherwise they are potentially more hazardous than vehicles without them. Drivers will by design rely on these features and must be warned if the vehicle knows they have failed. I don't love that the vehicle has already had a failure with only 1695 miles but this dangerous software concerns me more.

Car fire - started at the rear of the cabin between the cabin rear window and the truck bed the fire engulfed directly around and inside the fuel tank. The car is available for inspection as far as im aware at the tow / salvage yard the safety of myself and any passengers were greatly put at risk. The fire engulfed the inside cabin within seconds, and caused a total loss on the car. The problem has not been identified elsewhere. However the almost exact scenario has occurred in the manufacturers other 2021 model vehicles on the tahoe and yukon, with recalls on file for both for incorrect seal around the fuel tank, causing fuel tank fires. The car manufacturer does not want to help at all, they are willing to deal with insurance company and that is it, who will just pay out the value of the car. The police and fire crew local to the incident have ran reports on the fire. No warning lamps occurred before or during the fire. The car was operating as normal until the large explosion. There was no accident, nothing was hit, witnesses described small embers / flames flying up from the truck bed right before the big explosion, indicating there was fuel spitting out and catching on fire.

I discovered that the key to my 2016 chevy van unlocks the doors to my 2021 chevy silverado. I feel totally unsafe now when I leave anything of value locked in my pick-up. With auto thefts and break-ins at an all time high how can anyone ever feel safe locking valuables up in their vehicle. The chevy dealership where I bought it first didn't believe me but later checked with chevy and found out that gm ran out of key codes so they started to reuse them. People in the business of stealing cars or stealing the contents probably can wander thru shopping malls or parking lots get in and out of cars without the owner aware of it. What are the odds that I would have a key that opens two different vehicles and how many other keys like that are out there?

Purchased new chevrolet silverado at4 last week and with only 72 miles on the odometer a warning light appeared on instrument cluster stating “service brake assist”. Returned to dealer where purchased with 91 miles on odometer 3 days later. Dealer service department confirmed a faulty brake control module and ordered replacement part. New brake control module will arrive in 4 days and will be installed at that time. In the meantime, service manager said vehicle is safe to drive with existing brake control module. This is being submitted because of previous significant vehicle recalls on record for the same issue in 2018-2020. It appears the problem or some iteration of the problem has not been corrected yet in the 2021 models.

Purchased new, within a couple of days the srs supplemental restraint system light came on the info center in dash and would flash on and off with the airbag light on (red) it would do this for 15-30 seconds and then "reset" and then lights would go off. Was inconsistent but scared my wife, so I took the truck by the dealer and they said it was not a hard code in the system and may be a bug in the system and keep an eye on it... Well a few more days after it finally set a check engine light hard code and was taken to the dealer the next day. Found out if the light comes on the air bags are not activated, nice one gm. So after 3 days they changed the clock spring in the steering column and then find 3 hard codes for engine misfires. All before the 1st oil change... Come on man this is 2021 so while its in the 2nd time the guy has to order the part they dent the door and scratch the paint and now it back for 2 more weeks for paint and body and infotainment system issues updates poor quality and headaches. But wife still feels unsafe with the air bag failure issues.

I lost control of the vehicle when the road became bumpy. The vehicle was bouncing up and down pitching from side to side. I was driving the posted speed limit. This happened on the day I bought the vehicle and I was on my way home from the dealership. At first I thought the vehicle was acting like that because it was new. Nope. It's real. The truck bounces and pitches hard every time I hit a bump in the road. I even drove back to the location where it happened on the first day that I bought it and sure enough the vehicle acted the same way. The entire truck shakes and bounces violantly when I go over bumps. I'm talking about every thing. The second thing is that when the vehicle warms up it starts humming like an electrical type of hum or noise. The humming is coming from the passenger side of the vehicle and I can hear even when I'm standing outside of the vehicle on the passenger side. The transmission slips when I slow down and speed up again. The vehicle that I am driving is dangerious and shouldn't be on the road. City street or highway doesn't matter in my case. The truck will violently shake at the posted speed limit.

The initial call in for service it was taken in on 12292020/mileage 1020 for a oil change and a clunking noise coming back from the rear end at low speeds, while turning and going over bumps at all speeds. The dealership was able to hear the noise and advised that they cannot find out where the noise is coming from. The dealership advised that they submitted a ticket to gm for the noise. On 03022021/mileage 2797 the truck was taken back into the dealer for the same noise because its getting louder. The dealer again said that they heard the noise but cannot figure it out. They advised that they submitted another ticket with gm waiting to hear back from them they closed out the ticket on 03102021 with no answer from gm. I have also called gm customer service and spoke with on 03102021, and told me to call them back because they had to try and let the dealer resolve the issue and the dealer is waiting to hear from gm. The dealer did advise me that there was a service bulletin for 2020 chevy 1500 pick ups but nothing for 2021s so they can do nothing yet, the sound sounds like to me that the axels are going to come loose or the suspension is going to drop. I am afraid to drive the vehicle fearful that something is going to come off or the suspension is going to drop if I attempt to tow something. Thus causing pain, injury or death to myself or another innocent party. I am considering taking it to another dealer again to see what they say, but I feel this is safety concern all people who are hearing this noise on their 2021 chevy pick ups. I also would like to add that this truck has no suspension modifications of any type and is all stock. Thank you for taking the time to look into this. Also attached are the work orders from the chevy dealership. Thank you again

On thursday feb 18th is was snowing when I left work, drove around the beltway approximately 30 miles going on average 30-40 mph. No issues just bad roads. Right after I left the highway and turned on to a main road, I was approximately 1 mile on that road in the middle lane driving straight at about 25-30 mph when my new 2021 silverado (5000 miles) loss power. The battery and check engine light came on with no engine power. As the vehicle was coasting attempted to get off the main road, but didn't make it due to the snow covered roads and slush. Ended up in a merge lane still in traffic and was almost hit numerous times. Tried to restart and get to a safe location, but when pushing the start button the silverado would crank extremely long period of time and then final cutout. Was on the phone with on star where they put me in contact with the local police department who never showed and then left me a message they were coming out due to the inclement weather. Thanks. After talking with police dispatch on star setup a tow truck, but gave them the wrong address which was more than an hour away from my location. Once back on the phone on star stated they had to call the same tow truck driver/company which of course he was over an hour away. Once the tow truck driver arrived 3 hours after my truck broke down he said he was originally only 10 minutes from my location prior to on star sending him to the wrong location. What a mess. Have a loaner car because I have been told a fuel pump is on national backorder. Also that they will be replacing the valve springs which is another issue I think? Hoping to know more this week.

Their is a protruding "thumb joystick" which is used to set the speed up or down by using your thumb or finger. Multiple times now my hand has accidently swiped this "joystick" while driving along a 30 to 35 mph public street and this turns on and engauges the speed control at the last saved set speed. Usually 65 to 70mph highway speed. The vehicle will then start to accelerate very quickly and if your reflexes aren't what they used to be, well 2+2.

    2 days after picking up my 2021 Silverado Z71 from the dealership the truck lost power, dash was blank and all electrical systems were gone. Tried to restart the truck and wouldn’t fire. I jumped the battery and managed to drive it back to the dealership with no dash or touchscreen powered. The dealership said it was a bad cell in the battery and replaced it. Now i am hearing a squeaking noise coming from the drivers side front wheel. Mind that the truck has only 8,900 miles on it and sits in my driveway 5 days a week since and only use it as a weekend driver. So what could that be and should i be concerned?

    Purchased a 2021 Silverado brand new last year. At 8,800 miles the engine started backfiring with various codes. We were on our way to Texas to visit a terminally ill brother. After returning to California the dealer told us it’s a common problem and would cost over $10,000 to fix if the truck was not under warranty. They did not even provide a rental car! After a little research I really wish we never purchased this truck.

    I have a 2021 Silverado with 8,800 miles and have no issues. Remember that these motors have a plastic intake on them so you will here lift noise more than if it had an aluminum intake on it. I have towed with this truck with no issues. This truck has been very reliable.

    I purchased my 2021 Silverado brand new in February 2021. To date, its been to two different dealerships on seven different occasions for non-working auto start stop. Each time, they “diagnose” my truck with different issues, meanwhile my non-working auto start stop issue still persists. Second to that, since March of 2022, I’ve been advised that my truck has had a litany of trouble codes, some active/some history: Driver Steering Wheel Air Bag Deployment Loop Stage 1/Stage 2 Open; ECU Security Software Code Not Programmed; LIN Bus 1 Lost Communication with Device 8; Control Module- Internal Malfunction; Lost Communication with Power Steering Control Module; and Lost Control with Body Control Module. In spite of all these troubling codes, GM still can’t resolve my issue, or the trouble codes for that matter.

    At this point, GM can just buy this thing back from me, and deservedly mark it as a LEMON!!

    I bought my new 2021 custom 4 cylinder after driving it for say around 300 miles I been hearing loud noises either coming from the suspensions or transmission? The loud noise occurs when applied the gas pedal and when coming to a complete stop.
    Other issue is the GPS keeps logging off , and sometimes between acceleration and braking, the truck like jerks or kicks back not happy with it.

    I have a 2021 Chevy Silverado 1500 Custom Trail Boss I bought it brand new October 25th 2021. Today is February 22nd and the 2nd time in a week that I have had a complete brake system failure. The truck only has 6300 miles on it. Sent back to the dealership the first time don’t know what they did, they said it was a computer issue, I got it back and now a week later it happens again. I was told by the service department that they may have to order a part and that he had to talk to the technician, that was at noon, and I still haven’t heard anything back. This is a pretty serious problem to have and luckily both times it’s happened the truck has been in my drive way and not going down the road.

    2021 Silverado 2.7L. It has 16000 miles and been taken back to the dealer 4 times. Brakes periodically grind like metal on metal, suspension popping and rattling like the bed is loose, hard shifting, bad vibration on the road as if there is a knot on a tire (but not), vehicle jumps forward when coming to a stop to park or at stop signs, when starting the vehicle it jumped forward while in park, and vehicle transmission slips on first drive of the day every day. All 4 times taken to the dealership they inspect and tell me they can’t find any problems. Not sure what to do except sale it. I’ll never own another gm product…ever.

    My last 3 trucks were Fords. Thought I would try a Chevy so bought a 2021 Silverado with 16k miles. Now it has 18K miles and while driving on hwy I got all the same lights mentioned come on and lost power. Dealership said it was a problem with lifters. After reading all these comments, my truck is just another example of the same. 🙁

    I have 2021 Silverado 1500, less then 11,000 miles. Surprise…I have the same problem. Check engine, Traction control, engine light, service parking brake, service ESC and then the horrible engine knock. Took it to Chevy dealer I bought it from even after they said they didn’t have an appt for me. Pin damaged and absolutely no ETA to get it fixed. I think this is BS, they no this happens and what because of a bulletin they send kits to fix it? This was my first Chevy and will be my absolute last. What a scam to sell $50,000+ vehicles knowing this is going to happen and what GM says oh well. They were not going to get a loaner. Do they actually care how this affects there customers? I am a single female and this problem started at 5:30am on an interstate. I have heard alot of crap about GM in the past and I thought they got better. Surprise again…THEY DID NOT! I will never own another GM product and as soon as my truck is fixed I’m getting rid of it. You suck for thinking this is ok!

    I bought my 2021 Silverado duramax diesel engine on July 2021, it had great power and great mileage. On first month, blew heater hose and overheated the engine. On Nov 10, 2021 I saw two streaks of oil on my garage payment & took it to dealer. They said their was no problem I must have gone thru an oil spill with only 3000 miles. I got rid of it because it smells like an expensive lemon.

    My 2021 Silverado had lifters replace at 8500 miles and took more than month. I got it back and the following day took it out for a ride and within 25 miles began loosing power and skipping along the highway. If contacted the dealer once again to see what might be next. Wish me luck.

  • Roberto G

    Bought a new 2017 Silverado and I barely have 62,000 miles on it and already have to replace the transmission. I don’t pull anything or haul anything heavy with it. I know it dissent have enough miles to replace the transmission, parts are back ordered so it will take a while before I get my truck back

    At 12,000 miles my engine’s 8th cylinder blew in my 2021 Silverado 1500. The dealership has had my car with no call as to how long the parts will take to come in . (Been five days)
