Power locks locking and unlocking on their own
 

I have a 2006 Chrysler Pacifica that keeps locking and unlocking the doors. It can happen for no reason while I am driving and will do it for a few minutes. It also does it parked with the key out of the ignition. I went into the garage last night and heard it locking and unlocking. Also, as soon as I exit the car it will lock and put the alarm on. This is quite scary to me as I have two young children and do not want to lock them in the car. The car is no longer under warranty.
