Power lock intermittently failed on the rear passenger door. Door could not be locked or unlocked using the key fob or driver's control switch. This happened on and off at random. Resulted in the car constantly trying to automatically lock itself while driving because it could sense that the door was not locked while in motion.

Update from Mar 13, 2023: After having the actuator replaced, the 2nd door failed after 60,000 miles and has since needed replaced as well.
