Sounds like you have a piece of the internal lock mechanism sticking. If you are handy then you can pull the door panel and figure it out. If not, the dealer is but a phone call away lol. Seriously though if all other locks are unlocking then it has to be a lock component in the door. It could be a rod, actuator or even the latch itself.
Faulty door lock actuator. Replaced under warranty. I was told the repair cost would have been $462 outside of warranty.
