2021 CHEVROLET SILVERADO 1500 Complaints

Driving down the road and out of know where engine starting knocking and lagging, idled rough. Drove to dealer lifter failure was what was diagnosed. 10000 miles on the truck driven easy, no towing or anything. Dealer also informed me 3 other silverados were there for the same problem! Ridiculous!!

Safety restraint t system failure - airbag lights on and airbags advised will not deploy if in accident

Electric steering control and driver assist malfunctioning along with engine misfire Been to the dealership 3x they have reproduced the issue unable to repair Chevy also notified apparently many other vehicle of my same type have this issue Happens daily till vehicle has run for a bit Unsafe till then Started at about 13 k miles still ongoing

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?

I purchased my vehicle on 10/11/21 new with 4716 miles on it and on 10/27/21 a “service brake assist system “ came on along with the check engine light. I drove directly to Long Chevrolet and GMC of Athens, Tennessee. They scanned the codes and determine that the master break cylinder and associated system needs to be replaced. They kept the vehicle stating that the brake system could fail. It is now 11/6/21 and they have no estimated timeline on being able to get parts to repair my vehicle. I now have to make a payment on a vehicle I can not drive

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.

Too whom it May concern Our 2021 Chevrolet Silverado 1500 had check engine light come on 7/5/21 called Chevy Service department was told Bring vehicle in if Light flashes, Light went off Service department said if it happens again to bring it in . It happened again 10/12/21 took vehicle in to service was told it was something too do with lift & Technician reset something & Did our first Oil change as this was a New Truck bought in 01/13/21 from them . 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 . Service department said Engine was basically shot that engine lifters went bad & Probably had a bent pushrod. 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. This has been Long enough Chevrolet must recall these Vehicles & Apparently its All GM engines 5.3 & 6.2 whats it gonna take someone being Seriously hurt or Killed!!!!

Turned on my 2021 Chevy Silverado in my driveway and esc service notification popped up and check engine light popped up as well and then a loud clicking sound came from under the hood which turns out to be a bad lifter.

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. The failure mileage was approximately 1,100.

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.
