A week or so ago while washing my silver 05 Grand Caravan I leaned down far enough to make a surprising discovery of rust on the bottom of my rear quarter panel just in front of the back tire. After closer inspection, also found some bubbling of paint on the side panel right in front of tire. Took it into the dealer and found out I'm outside of the warranty and they have seen this problem before. Not an easy or inexpensive fix ($200-2500 per side). The cheaper bandaids will only slow the issue down. Guess there is a ledge under there that traps the water. Has anyone else had this problem? If so, what did you do and what color is your van? Dealer suggested I call Chrysler and plead my case.
