Car locked itself with driver and passengers inside car. no one could open doors from inside. the manual unlock would not unlock doors. driver was able to unlock his door by opening window and using the outside door handles. *tr this incident has happened three times. on another incident while parking, the valet asked to turn car off leave car keys inside car. as driver left the car and closed the door, the car locked itself (with the keys inside). this has occurred twice in the past couple of months.
