This is the 2nd time this has has happened. 1st time was a few months ago and only lasted 10 min or so. This time is been cycling the door locks for over 2 hours. If I hold the lock in the lock position it stops, but other than that it’s constant, lock, lock, lock, lock, etc... I tried unhooking the battery. I looked for door lock fuse, but no luck there. Took to the dealer and they couldn’t do anything. Said I’d have to make an appointment for them to reprogram the pcm. Anyone else have a issue like this?

I'm having this problem right now and not sure what to do? Did you find a solution?
Yeah, it happened a few times and then stopped. Hasn’t happened in a year or so.

Mine just stopped. It’s done a few weird things since I’ve had it. Lol. Once I walked out to it and all four windows were rolled down exactly half way.
