I believe I had the same issue  of an intermittent locking of the driver door (only the driver door has issues, all others lock fine).  To fix I opened the driver side door, pushed the door light plunger switch (located at the back edge of the door opening below where the door latches).  The switch should have a black rubber boot over it with a single screw at the bottom and is oval shaped, oriented vertically.  I pushed the switch in all the way and quickly released it several times and this seems to have at least temporarily resolved the issue.  Let me know if this works for you.  If so keep in mind the switch could be going bad and it should be replaced if this happens again.  Cheers!
