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.

" EXTREMELY DANGEROUS ENGINE WIRE HARNESS " I BELIEVE THE FAULTY WIRE HARNESS COATING WAS MANUFACTURED FROM 1991 TO 1996 BY MERCEDES BENZ. THE PLASTIC COATING THAT PROTECT THE WIRES FROM TOUCHING AS THEY GO TO EIGHT FUEL INJECTORS, COMPLETELY DISSOLVE IN MANY AREAS.....CAUSING A MULTITUDE OF EVENTS: 1) SUDDEN ENGINE FAILURE 2) ENGINE FIRES 3) EXTREME LOSS OF POWER, CAUSING CAR TO JERK INTENSELY WITH THE POWER STEERING GOING IN AND OUT MAKING IT "ALMOST IMPOSSIBLE" TO CONTROL CAR. I HAVE REPLACED THE "ENGINE WIRE HARNESS" ONCE, & NOW NEEDS ANOTHER ON MY 93 MERCEDES 500 SEL WITH 170,000 MILES (THIS WILL BE THE 3RD WIRE HARNESS). (M.B.U..S..A.) IS VERY MUCH AWARE OF THEIR "FAULTY HARNESS" AND HAVE BEEN SENT PICTURES OF CARS BURNED TO THE GROUND, THOUSANDS OF LETTERS AND PICTURES CONSUMERS CONSUMERS, BUT REFUSE TAKE RESPONSIBILITY FOR THIS "DEFECTIVE-PART" ((THEY REFUSE TO RECALL THIS POTENTIALLY DEADLY HARNESS)) THIS PROBLEM IS SO INTENSELY DANGEROUS TO EVERYONE ON A ROAD WAY, BECAUSE THE REACTIONS WHEN THESE WIRES TOUCH ARE "COMPLETELY UNPRODICAB E". MAKE MERCEDES STAND UP TO THE PLATE AND "R E C A L L " THIS EXTREMELY DANGEROUS E N G I N E W I R E H A R N E S S ! WITH MANUFACTURE DATES 1991 THROUGH 1996. (NOT POSITIVE OF EXACT YEARS, BUT SOMEWHAT ACCURATE) MY 1993 500 SEL STALLED IN MIDDLE LN. ON HWY. 280 IN SAN JOSE CA. ON 11-29-2007 @ 5:15 P.M. (NEAR 7TH STREET EXIT) NEARLY RESULTING IN MY DEATH. CARS TRYING TO AVOID ME DURING THEIR UNEXPECTED AND SUDDEN STOP AND/OR LANE CHANGES. CARS SKIDDING, SLIDING, LOSING CONTROL....IT WAS A NIGHTMARE!!!. IT'S A WONDER NO ONE INCLUDING MYSELF WAS K I L L E D. I'M 46 YRS OLD, & THAT WAS "THE MOST DANGEROUS SITUATION, & CLOSEST TO MY BEING KILLED THAT I 'VE EXPERIENCED!" THERE'S NO WARNING TO THE SIDE EFFECTS WHEN THE WIRE HARNESS WARMS UP AND THE UNPROTECTED WIRES BEGIN TO CROSS CURRENT WITH ONE ANOTHER. *TR

WHEN MY 1993 MERCEDES BENZ 500 SEL WARMS TO ITS NORMAL RUNNING TEMP. IT BEGINS TO ACT AS IF IT IS NOT GETTING FUEL. IT CUTS OUT INTENSELY AND THEN DIES OUT COMPLETELY. THIS IS VERY DANGEROUS WHEN PULLING OUT ANYWHERE. I WAS TOLD THAT IT IS THE FUEL INJECTION WIRING HARNESS. WHEN THE CAR FINALLY QUITS COMPLETELY, YOU ARE STRANDED ROADSIDE OF AT LEAST 15 MIN. UNTIL IT WILL START AGAIN. I HAVE BEEN TOLD THAT THIS WIRE HARNESS HAS CAUSED FIRES WHICH HAVE DESTROYED OTHERS WITH THIS SAME DEFECTIVE WIRE COATING. PLEASE HELP US MAKE MERCEDES DO A RECALL, THEY ARE RISKING OUR LIVES! I WAS STRUCK BY A DRIVER WHEN HAVING TO PUSH MY CAR TO THE CURB WHEN STALLING FROM THIS WIRE HARNESS PROBLEM. FORTUNATELY I WAS NOT HIT AT A FASTER SPEED. ALL I RECEIVED WAS SOME MAJOR BRUISING ON MY HIP FROM THE CARS BUMPER. I SUFFERED WITH PAIN FOR OVER A WEEK. I AM NOT FILING FOR GETTING HURT, ONLY TO FIX THIS WELL KNOWN DEFECTIVE COATING ON THE MERCEDES BENZ WIRING HARNESS. PLEASE HELP US WITH OBTAINING A RECALL ON THIS VERY POTENTIALLY DANGEROUS PROBLEM. THANK YOU! P.S SEPT 1 IS WHEN THIS PROBLEM STARTED AND HAPPENS EVERY DAY NOW WHEN THE CAR WARMS UP. THEY WANT 1400 DOLLARS FOR A NEW HARNESS WHEN THE 1ST ONE WAS MADE D E F E C T I V E L Y ! *TR

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. Older model years have had longer for reports to accumulate.
