2021 CHEVROLET SILVERADO 1500 Complaints

After starting the truck and placing in reverse the service power steering warning come on as well as service ESC. The steering wheel would not move. If I were driving at a higher speed a crash would be imminent. On the Chevy forums there are several other owners that experienced the same problem and the loss of steering happens randomly. After parking the truck and returning several hours later the warnings did not reappear. I called the Chevrolet dealership and they informed me that they cannot diagnose the vehicle if no service lights are actively showing. Then I called Chevrolet to report the issue and they informed me that there are no recalls and nothing can be done unless the warnings are active and to contact another service center. If the vehicle does this while i'm driving I most likely will be in a accident. The Chevrolet case # 9-12940772786

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated while driving 20 MPH and depressing the accelerator pedal, the vehicle shuddered, jerked, and hesitated to respond. There was no warning light illuminated. The contact stated that the failure had been recurring increasingly while driving. The vehicle was taken to an independent mechanic, where the vehicle was test-driven, but was not diagnosed. The mechanic determined that the failure was related to the torque converter. The dealer was not notified of the failure. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and informed the contact that it was a known failure.

When I am driving over 40mph and accelerate my breaks lock up. It's almost like I hit something really hard. It has done this at 70 mph and almost cause an accident behind me. My truck doesn't have automatic emergency braking on it. I have read a form a lot of people are having this same issue with this year and make.

The gas tank door will not stay shut. There’s is no damage something inside the bedside happened mechanical.

Leaking radiator with no ETA on parts availability and this is also an issue with the coolant valve being on back order and both have many reports of this failing as well with some google searches. The dealership has my vehicle and has been inspected by them. I also do not understand why radiators are not apart of the powertrain when it cools the most critical part the engine. If the Radiator fails the engine fails.

Rear tail gate opens when parked and while driving. It also opens when key has been removed.

Back in March 2024 the tailgate opened on its own only a few times. Now April 2024 it opened on its own several times without a button being pushed. After it opened it made several clocks like the tailgate is trying to lower. Now the tailgate button does not work and can only open it with the key fob

The key fobs for keyless start/lock/unlock stopped working and batteries replaced still didn’t work. Brought to dealer to be fixed. They replaced a sensor thinking it would be the fix- did not work. They found a corroded wire and replaced it. Asked them what happened and how it corroded. They said it was nothing we did wrong it just corroded. Cost $1000+ for fix for an issue that seemed to “just happen”

I dropped an ink pen between the drivers seat and the center fold down seat. While attempting to retrieve the pen I reached between the drivers seat and the console just forward of the seatbelt connector with my right hand. When I pulled my hand out a sharp piece of metal on the seat frame sliced the fatty portion of my hand below the thumb. There isn’t a guard to protect the hand in the event one reaches between the seat to retrieve an object. I also found the same sharp piece present on the passenger side seat between the seat and the center console. I took the vehicle to my local dealer and the service manager also noted the sharp portion of the seat. He too, sliced his finger while reaching between the seat and the console. I did warn him beforehand as to what could happen. He suggested the vehicle be brought in for service. This is not a functional issue. This is a design, material flaw issue which has the potential to created injury.
