What owners are reporting 2 most recent
Issues with the passenger side seatbelt not pulling to lock. It's jammed off and on. Doesn't work.
Seat belt retractors fail to retract and belt clip gets stuck in closed door. Dealer fixed once but refuses to fix at their cost. I believe this is a serious gm defect and a safety hazard because a half open jammed door will not open.
