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 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…
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.…
MY MECHANIC TOLD ME ON 11/3/2007 THAT THE WIRE HARNESS ON MY 1993 MERCEDES 500 SEL COULD CAUSE FIRE OR DEATH TO MY FAMILY AND THAT MERCEDES BENZ U.S.A. KNOWS ABOUT THE FAULTS IN THE WIRE HARNESS AND KNOWS THE PEOPLE ARE IN DANGER AND HAVE YET TO DO A RECALL ON YEARS (1992 THROUGH 1996) PLEASE HELP US GET A RECALL IN THE WIRE HARNESS BEFORE PEOPLE GET BURNT OR DIE THESE WIRES JUST FALL APART AND THEN TOUCH EACH OTHER AND THAT IS WHEN THE DANGER STARTS, THIS REALLY IS A SERIOUS AND DANGEROUS SITUATION AND WE ARE ASKING FOR YOUR HELP. THANK YOU! *TR
