What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Plastic rear view window of convertible top is distorted, hazy and impairs vision. Dealer stated the mfg's representative would not authorize repair/replacement. I purchased an extended 5 years warranty. Dealer sold me a "do it yourself" kit to restore but does not work. Faulty design.
The driver's side belt retractor was not working. The part was replaced at the owner's expense of $425.00. The dealer indicated, that there was no warranty and there was nothing they could do.
This was caused by corrosion due to the fact the unit was not sealed from moisture. Toxic fumes and smoke were instantaneous. When it shorted out, turning the key didn't stop electricity flow. The consumer had to disconnect the battery.
Seat belt problem with 1999 mercedes s500. Seat belt would not retract. I called mercedes benz technical support (twice) to ask if there was a problem with their seat belts. Their immediate response was that they had not received any complaints about seat belt failure.
Plastic rearview window has a distortion in it which causes poor driver's visibility. Window was looked at by a factory representative. This was a design problem with all mercedes benz convertibles. Rear window has not been changed.
Air conditioning system has been in for repair on several occasions and is still experiencing failures. Mjs
