Since my purchase of the vehicle Dec 2023, the tailgate opens on its own. Usually follows hitting a bump such as the rain gutter entering a store parking area. I have also had it occur while driving down the road. Have been told multiple times by my service personnel they have had same complaints from other Sierra 1500 but have no fix for the problem. They have offered to deactivate the electronic tailgate system but this is unacceptable to me. There is a recall for 2500 models with same issue but not for 1500-??s. This makes little sense.

As I was driving on the highway the upper top moulding from the grill came off causing scratches to the hood. This is dangerous if it flies off into the windshield. This has been an issue for GMC.

The tailgate unlatched while driving. This caused the paint on the tailgate to rub off on the jack of the trailer that I was hauling. This could have caused items in the back of the pickup to fall out onto the road. There is a current recall for 2021-2023 GMC Sierra's with the same issue, but my 2024 GMC Sierra is not included in the recall. The vehicle is going to be inspected tomorrow by the a body shop. There were no lights or messages prior to the failure.

UNKOWN. It came like that. I took the truck to the dealership to be inspected and I was told that it was a manufacturing problem.
