1996 Nissan Quest latches & locks problems

When front of vehicle is on a hill, door latch would not work properly. Sliding door will not remain open. Consumer felt this was unsafe because if a child had to go through that door it might close on the child. Dealer was not able to do anything.

1. Driver door lock will not open at lease once a day. Replaced actuator by dealer on 6/14/00, worked for about a year then started doing same thing again plus. 2. Sliding door opens and the ajar light comes on daily or whenever a bump in the road is hit. 3. Rear door has to be opened and has to be manually reset for all the doors to lock. The number of failures, 1890 is an estimate, every time I drive this car, which belongs to my wife the doors act as described, my wife has been complaining since 1998.
