2021 CHEVROLET SILVERADO 1500 Complaints

Engine began to shudder, vibrate and lose power on the highway. Multiple codes were eliminated - check engine, service park brake, service ESC, service emissions system. Loss of motive power is a safety issue. Vehicle currently at the dealer for service. I have been notified it is a lifter issue and major engine repair required. GM Authority and other online forums identify this as a known major field issue and continuing to grow.

while stopped,engine running,in gear,foot on brake the truck lurched forward approx 2-3 feet. when i tried to pull forward the engine was revving a much higher rpm's. moved down road approx. 1-2 miles, tried to turn around to return to a dealer near by and truck would not go into reverse...on-star reported to get engine/transmission service soon. reported to dealer, they checked the (code)? truck continued to run well....till it happened again....now it has happened a third time dealer has ordered parts to try to correct. dealer is trying, but no one seems to know what to do...

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.

Driving along a highway at 65mph and a lifter dropped or rocker arm failed catastrophically. Loud audible pops and bangs without warning no "warning lamps" lights or notifications at all. Towed it to dealership under their recommendation as opposed to driving it there. Also there's a clicking metallic jingle jangle in the driver side from unless 4wheel auto is engaged.

Upon first start with 6-8 hours of being parked, the first shift from gear 1 to gear 2 has a massive hesitation that cause all passengers to lurch forward. It has not caused in issues for the quiet street we live on but in a high traffic area it would effect safety of entering into traffic. This issue happens every morning.

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated while driving 65 MPH, the vehicle inadvertently stalled. Several unknown warning lights including the check engine warning light and the transmission warning light were illuminated. The contact stated that he was able to veer to the side of the road and turn off the vehicle. The contact stated that he restarted the vehicle, but the vehicle was shuddering and making abnormal sounds while driving. The vehicle was taken to the nearby dealer who diagnosed that it was a manufacturer’s error and that the engine and the gasket needed to be rebuilt. The manufacturer was notified of the failure and advised the contact that they would replace the engine instead of buying back the vehicle. A case was opened. The vehicle was not repaired. The approximate failure mileage was 15,000.

Upon starting the vehicle got a alert on the dash DIC of, "Reduced Steering Assist, Service Steering System", or something similar to that. The vehicle was very hard to steer so I shut it off and restarted it seeing if it would reset since its electric steering, but it did not reset and was still difficult to steer. I was able to drive it home carefully since I was close to my home. After I got home I opened the hood to look but saw nothing wrong. I restarted vehicle again and the steering was back to normal and power steering was restored. I am very concerned because if this happens during busy traffic it could result in loss of control and a crash.

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that he noticed that the front driver’s side bumper filler was slightly detached and was wearing down the panel. The contact took the vehicle to the local dealer and was referred to an auto body shop. The contact took the vehicle to the body shop and had the front driver’s side bumper filler and bracket replaced. The manufacturer had been informed of the failure. The failure mileage was approximately 3,000.

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.
