Continued from my original complait above. Took vehicle back to dealer for "sliding door failure to lock in the open position". door can be closed with finger pressure against the door. On a slight decline, door will unlatch from its locked open position and slam shut. I have to have someone hold it open during entry and exiting on a driveway with a slight decline. The dealer told me that the design has changed and it does not lock like the older Astro's. someone not aware of this will have a false sense of security and it could slam shut on someone entering or exiting the vehicle. This is definitely a saftey issue. Someone must look into this and get GM to create a sb to fix this problem. What is the maximum angle or pressure required for the door to stay locked in the open position?

Sliding door will not lock open. Can be pushed closed from the locked open posiiton with one finger. On a slight decline the door will unlatch, and slam shut.
