You would think they would have fixed this known problem with the '07s - but.....

I also had the problem on my 2007 at about 7000 miles. For a while I suffered with manually putting the window back in the track but figured the problem would only get worse.

The regulator was changed (under warranty/no charge) and no problem any more. According to the dealer, Bulletin 06-014 was not relevant to this problem - I don't know why (maybe because my car is an '07?).

Take it in!
