CAR STOPPED SHIFTING, CHECK ENGINE LIGHT AND ASR LIGHT APPEARED WHILE DRIVING. TOOK CAR INTO AUTO MECHANIC AND WAS TOLD WIRING HARNESS WOULD NEED TO BE TOTALLY REPLACED AND WOULD COST MORE THAN AUTO'S WORTH.

I OWN A 1994 S 420 MERCEDES-BENZ I AM VERY CONCERNED FOR MY CHILD'S SAFETY AND MY OWN SAFETY AS WELL. THE WIRING HARNESS IS SHORTING OUT EVERYWHERE... SHAME ON MERCEDES-BENZ OF AMERICA..THEY KNOW ABOUT THIS DANGER AND JUST IGNORE THE WHOLE THING.. I'VE RESEARCHED IT REALLY WELL AND THE SAME PROBLEM OCCURS OVER AND OVER WITH ALL CARS OF THIS VINTAGE..I WONDER HOW MANY PEOPLE WILL HAVE TO DIE BEFORE THEY RECALL ON THIS DANGEROUS SITUATION???THEY SHOULD STAND UP TO THE PLATE..

I GOT 94 E420 BENZ WITH DEFECT ENGINE WIRING HARNESS. THEY ARE CRACKING. THE IDLE IS ROUGH AND I GOT ENGINE CODE ERRORS. ONE TIME THE ENGINE FAILED ON THE SURFACE STREET. IT WAS LUCKY THERE WAS NO CAR BEHIND ME AT THAT TIME. MY MECHANIC TOLD ME THAT ALL MERCEDES MODELS FROM 91-96 HAVE THIS PROBLEM. THAT WAS SO SAD THAT NO ONE HAS TAKEN ACTION AGAINST THE FACTORY. *TR

VEHICLE CHECKED AND FOUND THAT INSULATION ON ALL OF THE FUEL INJECTION WIRING, TEMPERATURE SENSOR AND FAN THERMAL SWITCH HARNESS DETERIORATED CAUSING WIRES TO RUB TOGETHER. CONSUMER DISCOVERED THAT HARNESS INSULATION IS MADE OF VERY POOR MATERIAL. THE INSULATION BREAKS VERY EASY AT THE TOUCH AND TURNS INTO DUST. THE WHOLE WIRE HARNESS IS IN THE SAME SITUATION THIS IS A MAJOR SAFETY ISSUE CAN STALL OR SHUT OFF WHILE DRIVING AT HIGH SPEED. REPLACE OF WIRE HARNESS AT A COST OF$1500 WAS NEEDED TO FIX. *JB
