I have a 2012 Traverse with a strange issue regarding the door locks. Symptoms:

The driver door and tailgate will lock/unlock with key fob, driver door power lock switch or putting the car in Park. All other doors will lock with key fob, driver door power lock switch, or putting the car in gear but will not unlock. Anyone have any clues to what may be happening?

I've owned the vehicle for about 4 years now. Within the last few months, the door locks starting behaving this way. I've tried replacing the door unlock power relay which didn't fix anything. I'll check out the DIC settings and report back.

OK. I don't have the wiring diagram with me but I believe there is one relay for drivers door lock and another relay for the other doors. Check your relays, swap one with the other.

Thanks for pointing me in the right direction. I missed that there were two different replays for the power locks. For those who may come across this post with the same issue, the power relays for the door locks are behind the glove compartment. Here is the diagram:
