What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 1999 Mercedes-Benz W163, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

THE FUEL PUMP IS LEAKING FUEL ON TO THE GROUND WHEN CAR IS RUNNING I WAS READING SOME FORUMS AND MULTIPLE PEOPLE ARE HAVING THE SAME PROBLEM AND MERCEDES ISN'T HAVING THE PROBLEM FIXED AS IT IS POTENTIALLY DANGEROUS TO HAVE ANY FUTURE FUEL LEAKS DUE TO AGE I HAVE A 1990 MERCEDES R129 THAT HAS MORE MILES AND OLDER AND NEVER HAD A FUEL LEAK WHAT SO EVER... SO IM POINTING THE FINGER AT MERCEDES DUE TO THE FACT THAT THIS CAR WAS POORLY DESIGNED FUEL FILTER PLACEMENT AND FUEL PUMP SECURING AND SEALS.. *TR
Too few reports in this category for a page of its own — they appear in the full complaint list.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
