I have had this car since new. Several years ago, a random door unlocking and locking problem started. It is now happening just about every time the car is driven.
Always happen when: Car has 4 or more people in it (or are hauling something) and you take a sharp turn (left turn is worse than right turn). The doors will unlock themselves. The more "g's" you experience in the turn, the more often it happens. If you continue like on a winding road, the doors will automatically lock and unlock as you are driving.
Often happens when: Same conditions as above, but with the car not loaded. Again, the more G's. the more likely it is to happen.
Seldom but increasingly frequent - You stop the car and get out. The car automatically locks! If you lock it and walk away sometimes in will unlock by itself. It is nerve racking because now when I go to the mall, lock the car, many times I come back to the car and it is unlocked.
Any ideas? In 2004 I pointed out the problem to the Lexus dealer, Johnson Lexus of Raleigh and they couldn't replicate the problem. I am scheduled to take it in tomorrow and now that it is happening regularly maybe they can replicate it, but if there are any ideas out there on the problem, it would be helpful if I could suggest what the problem is.
