I had the same problem too. Car was just dead one morning with the "4WD not available" displayed on dash. Had to jump it, took about 30 minutes. Check engine light stayed on for a drive cycle. That was about 3 weeks ago. Took it to dealership last week for diagnosis, and obviously they couldn't pull any codes and found nothing wrong.
I suspect this will be the next service bulletin... (after the one they did for crooked steering alignment).
