The bolts attaching the front door window glass to the window regulator may come loose. This can cause the window regulator to become damaged and possibly causing the window glass to break. Some 2003 & 2004 models have been recalled for the issue.
Part that opens and closes the outside fresh air vent was stuck in the recirculate position. Dealer replaced the part under warranty which was just about to expire. Only other problem is the front brakes are starting to squeak a bit. Pads are original ones. Probably time for a change. No other problems to report
