Guys, hoping someone has some insight into this problem I'm having (I've tried searching the forum, but didn't have much luck).

The car has auto locking engaged. When I drive away, the doors all lock as normal, but you can't open the passenger or rear doors from the inside. You pull the interior door handles and nothing happens. The interior door lock levers appear frozen.

The driver's door operates as normal, however when you open the door, or move the locking lever it only unlocks the drivers door.

The only way to unlock all the doors is by turning off the engine, then using the key fob to unlock all doors. Using the fob locks and unlocks as normal.

It seems like the car is dead locking all the doors. Does this makes sense, and does anyone have any ideas on how to trouble shoot the issue?

Oh, and if you sit in the car with the doors unlocked (as I do when waiting for the kids after swimming), every now and then all the locks 'unlock' by themselves, even when they're already unlocked. Essentially as if you pushed the unlock button on the key fob after the doors were already unlocked!

Help!

Thanks

Rob
