Owners/service Manual problems of the 1999 Chevrolet Suburban

This is a design and a manufacturing defect. It's a manufacturing defect because the doors are failing in large numbers and it's a design defect because the doors can't be unlocked manually when the power locks fail. The dealer said the door actuators and latch assemblies must be replaced. What happens is rivets on the lock assembly are coming loose and when the window is half way down it hits the rivets causing the lock to jam and the door can not be opened. In a panic situation, collision or car fire the passengers not knowing why they can not open the door would have to climb over the seats to get out which may not be possible if there is a front end collision or fire.
