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
ENGINE WIRING HARNESS COVERING MATERIAL ON BOTH MY 1994 MB E500'S HAS DETERIORATED CAUSING SHORTS BETWEEN WIRES, ENGINE MISS-FIRING, HABITUAL "CHECK ENGINE" LIGHT BEING ON, ETC. HAVE DISCUSSED ISSUE WITH KNOWLEDGEABLE MB MECHANICS AND THIS IS A KNOWN PROBLEM ON 1991 --> 1996 MB'S. OBVIOUSLY THE WIRE COVERING MATERIAL IS DEFECTIVE AS THIS HARNESS SHOULD LAST THE LIFETIME OF THE CAR. MB AT THE VERY LEAST SHOULD PROVIDE REPLACEMENT HARNESSES AT NO COST TO THE CONSUMERS THAT PURCHASES THEIR AUTOMOBILES. FOR MB TO RESPOND THAT THIS CONDITION IS NORMAL WEAR & TEAR IS NOT FACTUAL! *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.
