Truck would not start - it left me stranded. The main body to engine ground strap had rotted off. I found there is a Chevrolet Customer Satisfaction Program (N252515590) for ground straps rotting for the same make/model/year as my vehicle, but for some reason mine isn’t listed by VIN number in the program.

Incident: Twice our Chevrolet Silverado 2020 Duramax has experienced while operating, sudden with no warning "reduced engine power" and "check engine light" the engine sounds very different and does not operate as it should and presents a safety issue when you are driving and traveling at a high rate of speed. These incidences occurred on 10-4-2026 and 10-23-2026. The vehicle experienced a sudden failure of the engine coolant control valve, triggering Diagnostic Trouble Code P1006. This component failure restricts proper engine thermal management and poses a risk of sudden engine overheating while driving. General Motors has formally acknowledged this identical part failure as a chronic manufacturing and safety defect via Special Coverage Bulletins N252508341 and N252508340, which extend warranty coverage to 15 years/150,000 miles. However, GM has arbitrarily excluded the 2020 model year from this coverage, despite the vehicle utilizing the exact same defective part assembly number as the covered 2021-2023 models. This identical component failure across model years constitutes an unaddressed defect pool that requires immediate regulatory expansion to protect consumers from unsafe engine component failure. please fix this situation TY

Trailer brakes keep disconnecting and connecting . Warning pops up on dash to check trailer connections. I may not happen for a hundred miles or does it 10 or 12 times in just a few miles.I've seen several complaints from on line reports but no solutions from GM yet. Very frustrating when trying to pull a trailer.

It said on the dash, "Brake System Failure 43MPH Top Speed," "Service ESC," and lights on were the ABS light, BRAKE light, Engine Light, and Wheel Traction light. My wife and my [XXX] son's safety were at risk while driving on a busy 75mph highway and trying to turn around and make it home as the brakes did not work and having to cross busy streets. It was not able to reproduce but my local mechanic found the bulletin from way back that had not been addressed by GM after numerous times to a dealer for other repairs. I then took it to a local GM dealer that confirmed software update was not applied and they did the repair and I was charged to pay even though this was a known GM issue that never contacted me about this potential fatal random occurrence that could happen after I have taken great care of this truck. There not any warnings before randomly losing power on the highway once she hit 60mph on the on ramp and just started failing slowly.

Had a misfire in cylinder 4 so I took it to the dealership to diagnose. It held compression and switched the plugs and still had the same misfire. They said it was a common issue that the lifters go out with the DFM. It only has about 50k miles on it and I am the original owner
