While driving 55+mph on a parkway the service parking brake, check engine light and the traction control light came on with a warning "Engine Power Reduced" which was dangerous because I could not accelerate and there was not a spot to pull over. This is frustrating due to the fact that I was having this same issue 6 months ago and Chevrolet said it was a wiring issue and it wasn't covered by the warranty because it had 42k miles. Chevrolet said it was a known issue but it was not at the level of a recall and it cost $1800 to fix.

Our 2020 Chevy 1500 Trail Boss was waiting for an ordered instrument cluster at service department. The surveillance camera, film the vehicle catch on fire after being parked for 2 days. The smoke started from the inside, and the vehicle engulfed in flames until the fire department came. After the fire was extinguished very little was left of the vehicle. Basically a frame and engine was the only thing left. The vehicle had a little over 70k miles.

I took my truck in for an oil change on 5/25 and 12 miles after words, my truck was thrown into reduced engine power mode, which dropped my speed unexpectedly as I was driving. Luckily, I was in a residential area so that did not affect my safety, but there is potential that someone could have this code come up on the highway and have their vehicle unexpectedly throttled in regards to speed. The reduced engine power mode was the result of a code related to an electrical issue that ended up being the coolant control valve for the engine. I took it to a Chevrolet dealership that did the oil change, and they inspected it and determined that that part was faulty And would need to be repaired. The problem comes intermittently because The dealership drove my truck some and the issue would occasionally go away. As the part needed is on a seven month back order, the vehicle is available for inspection if needed.

While driving brakes failed and codes came on saying brake system failure 43 mph, this problem apparently is a programming issue that will cost over 600 dollars because -??reprogramming-?? isn-??t covered. Brake pads were over 50% life and it is a very dangerous error.

A/C blower motor over heated and caught the electrical wires on fire under the dash. I had just left my house for work about 1 mile from home and the dash started smoking then a fire started under the passenger side glovebox parked the car in the middle of the street and I was able to exit the vehicle and put the fire out with a half bottle of water I had in the car. I then called 911 and I believe it was EAST Pierce fire department. They shortly arrived and confirmed it was an electrical fire and that there was no more heat coming from it. The fire department then gave me A ride home. The vehicle has been towed to Sunset Chevrolet in Sumner Washington where the Vehicle was purchased New in 2020.

The trucks installed trailer wiring can cause a traffic accident. The wiring harness is known to have electrical issues but is not being corrected under warranty. It is difficult to know of these issues until you hook up a trailer or camper. The trailer's brake light and turn signal are affected by the faulty wiring. The dealer narrowed the problem to being between the plug and fuse. Other people have voiced their concerns with the trailer wiring.

Electrical acutated tailgate will not come down. The truck came with a soft bed cover that locks. If my child was to hide in the bed somehow it would pose an immediate risk to life and health as the tailgate will not come down and does not have any type of manual override. The interior controls do not work to lower the tailgate, the key fob controls do not work to lower the tailgate.

Vehicle is at 67, xxx miles. Vehicle is losing power, check engine light, service 4wd, service esc, service power steering, service parking brake..... the gas pedal has locked on me already with my 3 small children in the truck at highway speeds. GM says it's fine. I have all the work orders where 2 different dealerships have "corrected" these issues under warranty. Go retrieve the vehicle and within a week Vehicle is back acting up. This truck is unsafe to drive on the roadway. I have not been offered a courtesy vehicle to drive while "warranty" work is being done. I am appalled and in fear for my children and my own life with this truck.
