1996 Mercedes Benz C220

MY 1996 MERCEDES C220 HAS A DEFECTIVE ENGINE WIRING HARNESS. THE CHECK ENGINE LIGHT CAME ON AND I TOOK IT TO MY MECHANIC. HE TOLD ME THAT THIS WAS DUE TO THE TYPE OF INSULATION THAT MERCEDES USED FOR THE WIRING AND THE ENGINE HARNESS NEEDS TO BE REPLACED ASAP. MERCEDES USED A BIO-DEGRADABLE WIRE COVER THAT WITH HIGH TEMPS CRACKS AND FALLS OFF. THIS HAS CAUSED THE ENGINE TO RUN ROUGH, STALL AND LOOSE POWER AND IS NOT SAFE TO DRIVE IN TRAFFIC. THIS SHOULD HAVE BEEN TAKEN CARE OF WITH A RECALL BY MERCEDES. MERCEDES HAS BEEN OF NO HELP EXCEPT FOR ME TO PAY TO HAVE IT REPAIRED. *TR

ENGINE WIRING HARNESS, AND THE TRANSMISSION WIRING HARNESS, AND THE IGNITION COIL HARNESS, DEGRADED TO THE POINT THERE ARE INCHES AND INCHES OF BARE WIRES TOUCHING AND SHORTING WHICH CAUSES THE ENGINE TO QUIT. ALL THREE SEPARATE HARNESS WHICH RESIDE WITH OTHER HARNESS WHICH HAVE NOT DEGRADED. THE ENGINE QUIT ON THE FREEWAY IN RUSH HOUR TRAFFIC AND NEARLY CAUSED SEVERAL ACCIDENTS AT 65 MILES PER HOUR. REPAIR SHOP WANT $3500 TO CHANGE OUT THE THREE HARNESS WITH NO ASSURANCE THAT THE PROBLEM WILL NOT COME BACK. *TR

RECENTLY THERE WAS AN ISSUE WITH THE CAR. THE TEMPERATURE GAGE WAS SHOWING THE VEHICLE AS HEATING UP. THE TEMP WOULD REACH CLOSE TO 120 F. AFTER FURTHER INVESTIGATION BY OUR MECHANIC, THE VEHICLE NEEDED THE ENTIRE ELECTRICAL WIRING TO BE REPLACED. OUR MECHANIC SAID THAT IF NOT REPLACED, THE CAR WOULD EVENTUALLY CATCH ON FIRE. THE ELECTRICAL WIRING IS FAULTY NOT DUE TO WEAR AND TEAR ON THE CAR BUT SHOULD HAVE BEEN RECALLED BY MERCEDES FOR FAULTY WIRING. THE WIRING HAS COMPLETELY DETERIORATED AND THE WIRES ARE COMPLETELY EXPOSED AND IF THE WIRES HAPPEN TO TOUCH EACH OTHER, THAT IS WHAT WILL CAUSE THE FIRE. IN ORDER TO GET THESE WIRES REPLACED, IT WILL COST WELL OVER $1500.00 TO REPLACE ALL THE WIRING. *TT

ENGINE WIRING HARNESS WIRE INSULATION IS BEGINNING TO BIODEGRADE AND CRUMBLE APART. CAR WILL NOT BE ABLE TO PASS EMISSIONS WITHOUT A REPLACEMENT PART, WHICH COSTS NO LESS THAN $1350 (FOR A WIRE BUNDLE AND HOOKUPS THAT ARE DOOMED TO FAIL AGAIN IN THE SAME WAY), PLUS 4-7 HOURS OF LABOR COSTS. CAR HAS LESS THAN 60K MILES ON IT AND IS IN OTHERWISE GREAT CONDITION. AFTER SPEAKING WITH THE MECHANIC, HE SAID ANYONE WHO OWNS THIS MAKE OF CAR WILL HAVE A MANDATORY $2000 WIRE HARNESS REPLACEMENT FEE SOMEWHERE ALONG THE WAY (AT LEAST ONCE, IF NOT EVERY FEW YEARS). EVEN WITH A REPLACEMENT, IT WILL ONLY POSTPONE THE ISSUE UNTIL THE NEW ONE INEVITABLY BEGINS TO BREAK DOWN. EXTREMELY POOR AUTOMOTIVE DESIGN! MERCEDES SHOULD BE HELD ACCOUNTABLE FOR WHAT APPEARS TO BE A MASSIVE DESIGN FLAW AFFECTING ALL CARS OF SEVERAL SIMILAR MODELS WITHIN A HALF-DECADE OR MORE TIME FRAME. THE MAKERS OF THE FAULTY PART ARE MAKING BANK OFF OF MANDATORY REPAIRS AND PART REPLACEMENTS DUE TO THEIR OWN NEGLIGENCE. THAT IS ABSOLUTELY WRONG AND UNETHICAL, AND THE MAKERS SHOULD BE HELD ACCOUNTABLE AND BE FORCED TO RECALL THE PART. *TR
