What causes the automatic doorlock to sound like a 3 round burst of a M-16 rifle on 2008 Chrysler Town & Country

The power lock on the front passenger door engages 3 times when it is told to lock by the remote, door lock button and when reaching 15 mph and it does not always lock. you have to hit it twice sometimes. i guess it is getting a lock-unlock-lock or an unlock-lock-unlock signal??anyone have any ideas?
