NHTSA Complaint #11629624 — 2023 GMC ACADIA

Since late 2023/early 2024, I started to notice that my liftgate was open, while the Acadia, a lease with less than 15K miles, was parked in the driveway, off. At first, I thought it was a mistake on our part, that we had accidentally hit the button on the remote to open it or had forgotten it open. As time went on, the incidences continued and I realized it was happening on its own, while the car was off! When the Acadia was at the dealership this fall for a warrant repair (a pump that GM knew was problematic but only has alerts out about for now), I mentioned the liftgate. Thankfully, the problem happened at the dealership too so workers could witness it. It's a major safety issue and a public safety issue. When the pump repair was occurring, I got a text from the dealership that the problem with the liftgate was my fault, that how I clean the inside of the car had affected the mechanics and that I would be on the hook for over $300 in repairs. I had no way to prove otherwise and opted to instead disable the open function using the dial on the driver door set to off and it has not opened. Fast forward to last week and GM has a recall on GMC and other pickups where this kind of issue appears to happening to tailgates and it instantly felt similar. I believe GMC Acadia's have the same faulty wiring and I should not be on the hook for this repair but GM should fix the problem.
