2002 Mercedes-Benz C-Class C240 4dr Sedan (2.6L 6cyl 6M)
I had to take my car(C240) in for a warrenty job 4 times. They weren't because of big jobs.. They were just minor jobs but I was very annoyed. I expected a better car than this from Mercedes. The things I had to get fixed were windows making clicking noise when closing, remote key not working properly, and the trunk not openning unless manually opened with the metal key. I expected more of a car since I paid $37000 for a tiny car like C240.
Get all bugs out before selling a new model to the public. Mercedes is not about mass production. Your main selling point is the image. Once you lose it, you got nothing.
