Recalls, owner-reported complaints, investigations and safety data

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.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.

Crash or fire reportedComplaints whose submitter recorded that a crash or a fire occurred. These are the reporter's own answers on the NHTSA form, not verified findings.

I WAS DRIVING DOWN THE ROAD WHILE MY CAR (1994 MERCEDES S500)STARTED TO SMOKE A GREAT DEAL. WHEN I WAS ABLE TO PULL OFF I WAS STRANDED FOR 6 HOURS UNTIL I COULD GET A TOW TRUCK. AFTER SPENDING $2000.00 DOLLARS TO GET FIXED IT WAS BROUGHT TO MY ATTENTION THAT THE PROBLEM THAT CAUSED ALL OF THIS TO HAPPEN WAS AN ENGINE WIRING HARNESS AND I WOULD NEED ANOTHER. I WAS ABLE TO DRIVE FROM SHOP BUT CAR CUT OFF IN TRAFFIC. I IMMEDIATELY TOOK IT HOME. I RESEARCHED THE ISSUE AND LOOK AT THIS: HTTP://USERS.ADELPHIA.NET/~INFOAGE1/COMPLAINTS_NHTSA_MERCEDES_WIRING_HARNESS_FAILURES_1991_1996.HTML I AM OUTRAGED! THIS IS CAUSING MANY PEOPLE AND CHILDREN TO BE PUT IN LIFE OR DEATH SITUATIONS WITHOUT ANY ANSWER OR HELP FROM YOU ALL. DO NOT WAIT TILL SOMEBODY DIES BECAUSE IT WILL HAPPEN. YOU HAVE THE EVIDENCE YOU NEED! I TRIED CONTACTING MERCEDES AND THEY WERE AS WORTHLESS AS THEIR FAULTY PRODUCT. *TR
