Call the Chrysler Customer Service Center, tell them that you are dissatisfied with the repair capabilities from your Chrysler dealer and you feel that they are not experienced or qualified enough to do the repairs properly, and then request that a Mercedes dealer do the repairs, and or replacement... DC will have to honor the service from a MB dealer if you make the call and place the complaint...

Make sure you get a TSB complaint # from them... Then just take the car to your local MB dealer and hope you get a mechanic that knows what the heck he's doing!!!
