NHTSA Complaint #11657356 — 2024 GMC SIERRA 1500

Twice in the last few weeks my tailgate has opened while driving the vehicle. Prior to this, the tailgate has never dropped while driving since the vehicle has been new. The tailgate was not down whenever I left, but it was down whenever I got to my location. I did not hit the tailgate button to drop the tailgate at any time before during or after this trip. On the one occurrence, items were lost from the bed of the truck, which could cause a road hazard for other motorists. There were no warning lights or notifications that the tailgate was open on the driver information center or elsewhere. I have service scheduled with the dealer on 5/2/25 to inspect the vehicle. I am unsure at what point in the trip the tailgate opened.
