I feel for you; I went through the same thing with my Liberty Renegade. It was a perfect Jeep, and my pride and joy, until I took it in for servicing. They messed it up really bad. The problem in my area is that all of the Chrysler, Dodge, Pontiac, Olds and Jeep dealers are owned by the same guy. So I was pretty much SOL...

Couldn't you have the Mercedes guys look at it (noob question)?
