Upon taking delivery of vehicle erratic electrical problem existed. Often only the front doors would like, leaving the back doors and rear door unlocked. Often upon inserting key in ignition, drivers seat would zoom forward pushing occupant against steering wheel. While driving, outside rear view mirrors would retract for no reason. Dealer has not been able to fix though many service notes exist. Lately, the amp gauge failed however amperage is not affected. Next the speedometer showed 38 mph while not moving. It is totally now inoperative, varying from never leaving zero to showing 80 while going 20 mph. Since I cannot trust the accuracy of any gauge, I have no idea how fast I am driving or any of the other vital instrument readings.

The contact owns a 2004 GMC Yukon. While attempting to open the driver's side door from the exterior of the vehicle, the latch pulled, but the door would not open. The latch would remain stuck in the open position; therefore, the door could not be opened from the passenger compartment as well. The contact must roll down the window and push the handle back into place in order to exit the vehicle with the interior door latch. On a separate occasion, all four doors experienced the same failure. While an occupant was seated in the passenger seat, he leaned up against the door and it opened. The occupant fell out of the vehicle, even though the door was completely shut at the time. The doors would not lock or unlock. The VIN was unable to be entered. The failure mileage was 70,000 and current mileage was 85,000.
