Ever since I purchased this vehicle the doors (both inside and outside) have periodiacally failed to unlock after shutting off the car, without hitting the unlock button either on the key or on the dash (this has occured on all doors except the drivers so far). I have taken it back to the dealer many times and since they can't find a problem they either won't or can't fix it. This is a safety issue because it is possible that the all the doors will fail to unlock trapping people in the vehicle. This is also troubling because there are no manual buttons to unlock incase the system fails. Whether it is a wiring problem, a problem with the master unlocking module or lack of repair knowledge with the dealership I don't know.
