The doors were locking by themselves, with the key turned off and being parked. Took the car to the dealer, and they realigned the doors.

The manufacture sent someone to look at the car and said that there was nothing that they could do about it, the time limit for the lemon law has already passed. The manual says that the doors will not lock with the key in the ignition.
