The second power door lock actuator has failed on this vehicle at only 24,500 miles. This time the RF door did not lock or unlock electronically. I replaced the failed actuator myself. The inside of the actuator had water in it that looks like it caused the small electric motor to fail. This was the same cause of failure last year when the LF door started not working in cold weather and later failed completely. I believe this is a safety concern as the doors no longer lock or unlock as expected. This opens the door to intruders getting in the vehicle and defeats the protection of an automatically locked door in roll over collisions. This is not an uncommon issue on this vehicle per my conversations with other owners. I have retained both failed lock actuators in the event someone would like to inspect them. It appears that the sealant that was used to seal the two halves of the actuator was not adequate to prevent water intrusion as there was water directly where the case halves meet.
