I have the SE trim level with the key fob. I had an auto locking experience the other day. I had the vehicle locked, and stood at the tail gate and unlocked it with the fob. Opened and closed the tail gate, and about 12 seconds later the vehicle locked it self. All doors and the tail gate locked. I have tested this to make sure it wasn't something else. I did not know that it would re-lock itself like that... good to know.
