What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
A cast aluminum wheel on my 2008 mercedes benz cls63 amg cracked due to a casting defect. In the inside lip of the rim of the wheel at the outer diameter is a void, or hole, that was created by a an air bubble that was entrained in the molten metal but could not escape the mold before the metal solidified.
A mercedes-benz 2008 cls63 amg has four oem cast aluminum wheels with large casting defects in the form of debris collected at a knit line around its circumference. The other three pictures show the knit line as well as mold debris.
A few days ago I noticed a very strong fuel smell after filling up my car at the gas station. I took my car to the dealership and they said that the fuel tank is leaking and both fuel sending units need to be replaced.
I am concerned about the vehicle's saftey while driving at freeway speeds - the car shakes. The manufacturer refuses to replace the wheels stating no defects or recalls have been issued.
