Mercedes-Benz 500SEC

VEHICLE STALLED TO DEAD THREE TIME, ONE ON AN INTERSECTION. SYMPTONS STARTED WITH ROUGH IDLE, MISFIRING AND STALL. AFTER INSPECTION OF UPPER WIRING HARNESS (RECOMMENDED BY A FRIEND) THE CONCLUSION WAS BARE AND DESINTEGRATED WIRES CAUSING SHORT CIRCUITS EVERYWHERE IN THE CAR, PUTTING ME AND MY FAMILY AT RISK. IT IS AN EXPENSIVE REPAIR AND I CAN'T DRIVE THE CAR UNTIL MBUSA GIVES A SOLUTION WHICH I'VE HEARD THEY LOOK LIKE UNAWARE. I OWNED OTHER MERCEDES MODELS AND WE ALWAYS HEAR THAT THIS…

WIRE HARNESS DEFECT CAUSING SHORT IN SYSTEM SMOKE INSIDE THE VEHICLE WHILE DRIVING ON A COUNTY ROAD IMMEDIATELY PULLED OVER CUTTING OTHER DRIVERS OFF JUST TO GET VEHICLE IN A SAFE AND SECURED LOCATION.

WHEN THE ENGINE IS RUNNING AT IDLE, THE ENGINE WILL MISS IN A RANDOM MANNER UNTIL THERE IS A LOUD POP FROM THE RADIO SPEAKER, THE BATTERY LIGHT COMES ON, AND THE ENGINE STOPS. SOMETIMES THE ENGINE WILL CONTINUE TO RUN, CONTINUE TO MISS, UNTIL THE ENGINE EVENTUALLY STOPS. WHEN RUNNING AT SPEED AND THE ENGINE IS UNDER LOAD THERE IS A LOUD POP FROM THE RADIO SPEAKER, THE ENGINE MISSES, BUT THE ENGINE WILL KEEP RUNNING. THE MB DEALER AND AN INDEPENDENT SHOP BOTH INDICATED THE WIRING HARNESS…

THE FUEL INJECTION WIRING HARNESS HAS INSULATION THAT IS BADLY CRACKED AND FLAKING OFF CAUSING FAULT CODES AND POOR RUNNING. THE BODY HARNESS HAS CRACKED INSULATION AS WELL. WHILE THIS IS AN OLDER CAR IT IS LOW MILES AND HAS SPENT ITS LIFE STORED INDOORS. I HAVE A 1968 MODEL AMC CAR. THE WIRING IS FINE STILL. THIS WAS A SERIOUS DESIGN FLAW FROM DAY ONE. IT WOULDN'T BE SO BAD IF THE REPLACEMENT PART WAS NOT SO EXPENSIVE - 750 DOLLARS. *TR

THE ENGINE / FUEL INJECTION WIRING HARNESS OF MY 1993 MERCEDES-BENZ 300E 156000 MILES), HAS CRACKED INSULATION THROUGHOUT AND IS BEGINNING TO SHORT-CIRCUIT WITH THE RISK OF CAUSING DANGEROUS ENGINE MALFUNCTION--AND EVEN FIRE--INSIDE MY ENGINE COMPARTMENT. I HAVE READ MANY REPORTS OF OTHER MERCEDES-BENZ CARS OF THE SAME AGE RANGE HAVING THE EXACT SAME DEFECT. THIS IS A KNOWN ISSUE WITH MERCEDES THAT THEY REFUSE TO RECALL. *TR

MASS AIR FLOW SENSOR WENT BAD , COZE OF WIRING HARNESS .. *TR

ENGINE LIGHT ON DUE TO FAULTY ENGINE WIRING HARNESS. MANY ELECTRICAL PROBLEMS, INSULATION CRACKED ALL THROUGHOUT HARNESS. REQUIRES REPLACEMENT!! *TR

TL* THE CONTACT OWNS A 1993 MERCEDES-BENZ 500 SEL. THE CONTACT STATED THAT THE VEHICLE WOULD STALL SPORADICALLY WITHOUT WARNING. THE VEHICLE WAS TOWED TO A LOCAL MECHANIC WHERE THE CONTACT WAS ADVISED THAT THE VEHICLE HAD OVERHEATED AND CAUSED SEVERAL WIRES TO MELT. THE VEHICLE WAS NOT REPAIRED. NEITHER THE DEALER NOR THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 116,000 AND THE CURRENT MILEAGE WAS 125,000. THE VIN WAS UNAVAILABLE.

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…

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…
