2005 Mercedes-Benz S Class Problems

Owner-reported complaints filed with NHTSA, grouped by component

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

report

AIRBAG LIGHT CAME ON IN 2005 SMART CAR. MAINTENANCE BOOK SAYS GET TO DEALER IMMEDIATELY, SO WE DID. THIS IS A COMMON PROBLEM THAT SHOULD BE A RECALL. THE WIRING HARNESS NEEDED REPLACED. *TR

report

From owner reports, verbatim

MERCEDES BENZ S 500 HAD TOTAL BRAKE FAILURE. VEHICLE HAS ABOUT 12,000 TO 14,000 MILES ON IT. DEALER IS TRYING TO BLAME BRAKE FAILURE ON RUST ON ROTORS DUE TO LACK OF USE OF VEHICLE. I DON'T THINK THE MANUAL WARNS ABOUT THIS. SOUNDS LIKE A MAKE UP STORY TO ME. I HAVE HAD MERCEDES VEHICLES FOR ABOUT 30 YEARS AND NEVER HAD A PROBLEM LIKE THIS BEFORE. BRAKE FAILURE CAUSED AN ACCIDENT BUT SINCE AT VERY LOW SPEED NO INJURIES. IF IT HAD HAPPENED AT A HIGH SPEED IT COULD HAVE LED TO SERIOUS INJURIES OR DEATH. *NM

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.
