WIRING HARNESS IS COMING APART AT THE SEAMS. CAUSES ENDLESS CHECK ENGINE LIGHTS AND OTHER PROBLEMS. I DON'T UNDERSTAND HOW A GARAGED CAR CAN HAVE THIS PROBLEM. *JB

I OWN A 95 E320 MERCEDES BENZ WHICH HAS 98,000 MILES. SINCE I'VE PURCHASED THIS VEHICLE I HAVE ALWAYS MAINTAINED THE CAR PROPERLY; I CHANGE OIL EVERY 4,000 MILES, I CHANGED THE TRANSMISSION JUST LAST YEAR, ETC. RECENTLY THE SMOG PUMP WORE OUT SO I ASKED A CERTIFIED MERCEDES BENZ TECHNICIAN TO REPLACE IT. AFTER THE REPLACEMENT, HE INFORMED ME THAT HE FOUND ALL OF THE FUEL INJECTION WIRE HARNESSES TOTALLY STRIPPED OF THEIR INSULATION INSIDE THE OUTER FABRIC COVER. HE SAID THE WIRES WERE TOUCHING EACH OTHER AND IT IS IMPOSSIBLE TO FIX. HE ALSO SAID THAT SEVERAL MERCEDES BENZ DEALERS KNEW OF THIS PROBLEM AND IT WAS COMMON KNOWLEDGE TO THEM. AFTER CONTACTING THEM, MERCEDES BENZ SEEMS TO THINK THIS PROBLEM IS NOT OF THEIR CONCERN BECAUSE THE EXPIRATION OF ITS WARRANTY, SO THEY REFUSED TO REPLACE IT. THIS IS A DEFECT THAT COULD INJURE BY ACCIDENT OR START A FIRE AND NOT A WARRANTY PROBLEM. MERCEDES-BENZ NEEDS TO RECALL THESE CARS AND REPLACE THE WIRE HARNESS BEFORE SOMEONE IS KILLED OR BECOMES INJURED. *JB

THE TECHNICIAN DETERMINED THE WIRING HARNESS BETWEEN THE FUEL INJECTOR AND IGNITION WAS DETERIORATING AND COULD OVERHEATING. THERE IS A NHTSA RECALL, # 95V031000, REGARDING THE WIRING.

WIRING HARNESS IN 1995 MERCEDES BENZ E320 DETERIORATED CAUSING THE VEHICLE TO STOP ABRUPTLY AND HAD TO BE TOWED - THIS IS A KNOWN PROBLEM WITH THESE CARS AND MERCEDES HAS NO RESPONSE TO CORRECT OR DISCOUNT THE REPAIR PARTS - PAID 3200.00 TO REPLACE ENGINE HARNESS, FUEL ACTUATOR, TRANSMISSION WIRING HARNESS - *NM

MY 1995 E320 WITH APPROXIMATELY 130,000 MILES BEGAN TO EXHIBIT UNUSUAL PERFORMANCE CHARACTERISTICS, ROUGH IDLE, OCCASIONAL STALLING AT LIGHTS. WHEN I TOOK IT TO MY LOCAL MECHANIC, THEY INFORMED ME THAT AS THEY BEGAN TO INVESTIGATE WHAT THE PROBLEM MIGHT BE, THE INDIVIDUAL WIRES IN THE ENGINE WIRING HARNESS WERE CRUMBLING UNDER THE SLIGHTEST PRESSURE, MAKING ANY REPAIRS EXTREMELY RISKY WITHOUT HAVING THE ENTIRE HARNESS REPLACED AT A COST OF APPROXIMATELY $1800. THE FACT THAT THIS HAS BEEN WELL-DOCUMENTED FOR SEVERAL YEARS IS TROUBLING, ESPECIALLY GIVEN MERCEDES' REPUTATION FOR CARS THAT WILL RUN FOR YEARS WITH PROPER REGULAR MAINTENANCE. OBVIOUSLY MBUSA IS AWARE OF THE PROBLEM, SINCE DEALERS STOCK THE HARNESS. *JB
MERCEDES BENZ M104 ENGINE ELECTRICAL WIRE HARNESS INSULATION FLAKES OFF AND SHORTS OUT WIRES. POSSIBLE ENGINE FIRE COULD RESULT. MANUFACTURER HAS REPLACED SOME OF THESE IN A RANDOM FASHION, UNDER A GOOD WILL WARRANTY. *NM
IT HAS COME TO MY ATTENTION THAT MERCEDES AUTOMOBILES SOLD IN THE UNITED STATES IN 1994 AND 1995 WERE EQUIPPED WITH "BIODEGRADABLE" ENGINE ELECTRIC HARNESSES.

IT HAS COME TO MY ATTENTION THAT MERCEDES AUTOMOBILES SOLD IN THE UNITED STATES IN 1994 AND 1995 WERE EQUIPPED WITH "BIODEGRADABLE" ENGINE ELECTRIC HARNESSES. THE INSULATION ON THESE, INCLUDING MY CAR, HAVE DETERIORATED AND BECOME UNSAFE, CAUSING SHORTING BETWEEN WIRES. MY INFORMATION IS THAT MERCEDES HAS REFUSED TO CONSIDER THIS A RECALL ISSUE. REPLACING THE HARNESS COSTS APPROXIMATELY $1,400. IN ADDITION TO THE COST, THIS IS A REAL SAFETY ISSUE. MY REQUEST IS THAT MERCEDES BE CONTACTED AND CONVINCED THAT IT IS IN THEIR BEST INTEREST TO REPLACE THESE HARNESSES BEFORE IT CAUSES SOME EXPENSIVE AND DANGEROUS FIRES. *JB
MY 1995 MERCEDES E320 ALMOST CUT OFF AT IDLE AFTER SEVERAL TRIPS AND COSTLY REPAIR BILLS . FINALLY DIAGNOSED AS FAULTY WIRING HARNESS. WAS TOLD BY MECHANIC THAT MERCEDES HAD A PRIVATE RECALL. DUPONT MADE SOME BIODEGRADEABLE INSULATION FOR MERCEDES THAT JUST FEKK APART. THISWAS NOT FAIR TO CONSUMERS.*AK
