NHTSA Complaint #11661778 — 2024 GMC SIERRA 2500

My truck is experiencing an issue that is already a recall for similar trucks, but my VIN is not included in the recall. My tailgate opens on its own. This sometimes happens when I am driving down the road. This is a safety risk because if I am hauling something in the back, and the tailgate drops down, there is a chance the load could fall out of the truck and harm another vehicle or person that is behind my truck. I brought the truck to the dealer and they said they could not find any evidence of this issue, even though they stated that it is a known issues with these trucks. There were no waring lamps or messages. The only symptoms are that the battery can die if the truck is not used for a day or more and that the tailgate opens on its own whether the truck is parked or driving.
