The interior door handle chrome is peeling off, and it cut my wife's hand today. There are 3 of the 4 doors that have it peeling, and I am worried one of my children will cut there fingers also.

Driving at 70 MPH on highway. Vehicle gauges begin to act erratically, vehicle heaves and lurches, then 100% power failure. Nothing worked, even hazzard lights. Airbag light flashing on and off. Was able to put vehicle in neutral and move to the side of the road where the vehicle stopped. There was no power at all, had to manually open door locks. After 10-15 minutes, the power came back on and I was able to restart the vehicle and drive home. Happened again on 3/23/14. Again driving at highway speeds, the electric components (radio, gauges, power cord accessories) begin acting erratically and then 100% complete power failure while driving. The gm dealer cannot duplicate or find the problem. I feel 100% unsafe in the vehicle especially with my kids.

Driver side power door locks work intermittently. Horn sounds indicating door is locked however it doesn't lock. Also remote start does work leaving vehicle a target for theft. Also three of four of the exterior door handles broke and had to be replaced.

The 2008 gmc yukon and 2008 gm suburbans have a widespread well-documented, repeated failure of the door lock actuators as a result of a defect which gm will not address via recall. I have had two separate incidents of failed door locks in my 2008 gmc yukon. When the actuator fails, my children are able to open the car door while the car is in motion. Gm should be responsible for these expensive repairs even after the warranty period expires since the door lock actuator failures are widespread, common (even occurring repeatedly in the same car) and create a danger of children potentially falling from the car while the car is moving.

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.
