I taken it to Darcars (formerly Courtesy) in Rockville and I've taken it to Koons in Tysons Corner. Koons has ordered the new rear differential (to get rid of that "humming" noise) which should be in this week (covered by warranty). I'm going to ask them to keep it a few extra days and hopefully it won't start for them. And to Extensive: I hope this issue is taken care of for you by some new batteries in the keys but don't count on it. There's another thread that been started about this "Mystery starting problem."
