Defect Description:
SEAT BELTS
Potential Consequences:
On [XXX], my [XXX] son was riding in the back seat of our 2025 GMC Hummer EV (VIN: [XXX] ) and reported his seatbelt felt loose. I pulled over and discovered the seatbelt bracket was completely detached from the vehicle frame. The bolt was present, but the nut that secures the bracket was entirely missing, leaving the belt nonfunctional and my child at risk of serious injury or death in the event of a collision. This is a catastrophic failure of a federally regulated safety system. I immediately contacted GMC and the dealership, explained the issue, and stated the vehicle was unsafe to drive. Despite this, I was told to drive the vehicle in for service on 6/9. The dealership confirmed the nut was never installed during manufacturing. However, instead of repairing the defect properly using OEM hardware and torque specs, the dealer used a generic lock nut found in their shop and said it “should hold.” No engineer signed off on the repair. There were no warning lights or messages. The issue became apparent only after my son noticed the looseness. The vehicle also has other documented issues: mirror folding failure, seat cushion defect, hydraulic frunk failure, swing gate malfunction (fixed), and a squeaky rear door. All were diagnosed on 2/28/25 and parts were ordered. I received no follow-up. When I returned on 6/9, nothing else was repaired. The advisor said the original technician had left and the new one couldn’t proceed. I also own a second 2025 Hummer EV (VIN: [XXX] ) and am now concerned about its integrity. This experience has caused ongoing emotional distress. GMC’s failure to inspect, respond, or properly repair a critical seatbelt defect demands NHTSA investigation and possible recall.

ELECTRICAL SYSTEM
Potential Consequences:
When it rains, within 24 hours, the windows do not automatically move down enough to open the door on command of pulling the door handle. This disallows the ability to close the door back if the door is open, barely underneath the lip of the sky panels. Because of this power loss, the mirrors do not open, the door locks do not work, and the windows do not work. To be able to re-close the doors, the sky panels must be removed and either left off or replaced. Essentially rain leaks into the body where wiring that controls door locks, door windows, causing electrical failure of this circuit only. After some hours of time without intervention function, restores, presumably due to drying out of wet parts.
