| 2008 gmc yukon xl denali. driver door and driver side rear locks failed. with auto locks, the locks on all doors engage when the car is in gear. granddaughter sitting in rear seat in booster with seat belt. driving vehicle, she pulled on door handle and the door opened. stopped vehicle and attempted to lock doors with both key fob and interior switch, neither door would lock. able to lock doors manually. unaware of the problem until incident. she could have fallen out of vehicle if not for booster and seat belt. no warning noted or posted on driver information center. incidentally, when key fob lock is activated, car alarm is activated, however driver door and rear door are not locked. vehicle does not realize this and remote start function still operates. now car can be started, but anyone can just walk up and drive off in the vehicle, because the door locks are not functioning. most concern is for safety of passengers, especially children. the autolock doors with gears engaged is an advertised safety feature. very dangerous when this system fails...especially with no warning lights to indicate failure. would appreciate a recall, or at the very least a warning to owners that this could occur and create a hazard. | |||

| Door lock failure. power locks on 3 out of 4 doors have failed within the first 30,000 miles, under normal usage. over $600 to repair two doors, but failed again. this is a potential safety hazard as these doors cannot be unlocked and then opened from the outside. | |||
