Dash is cracking badly on its own. Is cracking also where airbag is held. Pieces can fly as projectiles and cause bodily harm when airbag deploys.

When car has been unused for a period of time, the right rear brake makes noise when the car is moved. This happend in either forward or reverse. Even after driving for a short period of time, the noise is still evident. Under warrenty, I asked the dealership to resolve. They indicate this is an ongoing investigation by GM. I purchased the car new in July 2021. This problem has persisted since purchase. I have reported it multiple times to the dealer but they pass it off as GMs problem. In reviewing other similar complaints for the 2020 model, it was resolved by changing the brake pads to a different material. Surely GM can find a cure after 3 years since production.

Headlights in on position, every few minutes both left and right headlights along with DRLs flicker off and back on very quickly.

1 - the failed component is the tailgate. The tailgate lowers automatically without any input from me while the vehicle is in operation. It has happened three times since buying the truck in February 2024. 2 - During the third event, I was backing up my Airstream trailer into its storage building when the tailgate dropped. At that time, I was negotiating a sharp turn in reverse and the tailgate came in contact with my trailer's propane tank housing. Both the tailgate and the propane tank housing were damaged (see photos). 3 - It was not until recently that I learned of a recall for the same condition on other trucks like mine, but for some reason my truck doesn't seem to be included even though it has the same condition as those trucks that are included. The tailgate and my trailer have not yet been inspected by any third parties (manufacturer, police, insurance, etc.), and no repairs have been made yet. 4 - There were no warning signals (either visible or audible) that the tailgate was down while the truck was in operation.
