Yes, Address the problem ASAP. If there's no rust, remove the weatherstripping and apply a quality car wax in the track area, and do not rub it off, it will repel the water if it does get in there. Do not put a rust inhibitor like por 15 on unless there is rust there. Also keep the area clean and dry, and try to put your car under shelter when in rains.

I'll keep you posted when i hear from Chrysler.
