NHTSA Complaint #11600069 — 2024 GMC SIERRA 3500

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.
