Brake pads have excessive squealing. Squealing implies incorrect pressure to rotor to stop the vehicle, which highly concerns me as an operator. According to the dealer where I reported the issue, there is a technical bulletin that approves replacement of the brake pads for free if reported in first 7500 miles. My truck exceeded that mileage when I noticed the squealing. If this was a recall for the defective brakes, the dealer would cover the costs to repair, but not for a technical bulletin according to the service department, and confirmed…

When attached to a trailer with solar panels, the truck will intermittently disconnect the trailer electronics which disables the trailer brakes and trailer lights. This is because the solar energy is back flowing to the truck via 7 pin connector and overloading the circuit. Having a truck disable the trailer brakes and lights intermittently is very dangerous. Earlier model years of this truck do not suffer this issue. GM is aware and has TSB but no solution has been found on the truck side without disabling the solar panels on the trailer.

These failures occurred in extreme desert heat, where temperatures in [XXX] reach 120°F. A vehicle that repeatedly fails to start in these conditions creates a serious safety hazard, including risk of heat‑related medical emergencies if stranded.

Radio has zero sound - the issue is the radio sound also has the blinker sound, hands free safety/navigation guidance along with the On Star safety function. None of that is functional. The dealer states it's a known issue and parts are not available. How can this be when they keep building new units. GM has been contacted with zero help and no response around my safety concerns. While it seems like a small thing when we say radio I'm not concerned with the lack of music but this system controls way more than music.

I was in an accident on October 20th 2022 while driving home. U had just reached the top of a sharp crest on a two way road. As I started to straighten out the wheels coming out of the turn I noticed my direction was still as if I was turning the wheel. I tried to brake and pressed the brake but it went to the floor and the truck kept going. I collided with the other vehicle and it was a miracle neither of us were seriously injured or killed. We had problem with the steering box about 2 years ago and had to have it towed to the dealership. The …

My truck wonders down the highway. It has been to the dealership well over 4 times. They have aligned the truck multiple times, changed the steering gear box, changed the power steering pump, changed tires and nothing fixes it. It takes constant adjusting of the steering to stay in my lane on any road. Quite pitiful for a $90,000 truck. It is currently at the dealership for the THIRD time in the past 7 days because they can’t get the truck to stop leaking fluids since changing the power steering pump.
