There is a recall already from GM on this issue, but for some reason our VIN is not included. This is a well documented issue. We have video of this occurrence if necessary. The dealer said it’s water in the tailgate switch.”

NHTSA complaint #11721418, filed 2026-03“Tailgate opens by itself. This happened 3 times in 2 hours while the vehicle was parked. I tow a 5th-wheel trailer. If this happens when towing it can cause a catastrophe.”
