TL* THE CONTACT OWNS A 1993 MERCEDES-BENZ 300SD. THE CONTACT STATED THAT THE INSULATION HAD EXPOSED AND BURNT WIRES. THE CONTACT CALLED ARLINGTON MERCEDES-BENZ (585 N GLEBE RD, ARLINGTON, VA 22203, (703) 525-2100) AND WAS INFORMED THAT THEY NO LONGER HAD PARTS FOR THE VEHICLE.

THE ENGINE WIRING HARNESS OF MY 1993 MERCEDES-BENZ 300SD HAS CRACKED INSULATION THROUGHOUT AND IS BEGINNING TO SHORT-CIRCUIT WITH THE RISK OF CAUSING DANGEROUS ENGINE MALFUNCTION AND FIRE. I HAVE READ MANY REPORTS OF OTHER MERCEDES-BENZ CARS OF THE SAME AGE RANGE 1992-1997 HAVING THE EXACT SAME DEFECT "ECO WIRING". JUST LOOK AT ANY ONLINE FORUM OR TALK TO ANY MERCEDES TECHNICIAN. THIS IS A KNOWN ISSUE WITH MERCEDES THAT THEY REFUSE TO RECALL.
I PURCHASED A 1993 MERCEDES 300SD IN AUGUST 2009. THE CAR HAD 58,000 ORIGINAL MILES ON IT. I WAS THE SECOND OWNER. I TOOK THE CAR TO A LOCAL IMPORT CAR/MERCEDES SERVICE CENTER TO HAVE IT CHECKED OVER. THE MECHANIC POINTED OUT THAT THE MAIN ENGINE WIRING HARNESS AND THE GLOW PLUG WIRING HARNESS HAD SERIOUS PROBLEMS. THE WIRES HAD SERIOUS CRACKS AND MUCH OF THE INSULATION WAS MISSING. I WAS INFORMED THAT UNLESS THESE WIRING HARNESSES WERE REPLACED THERE WOULD BE SERIOUS PROBLEMS. I REPLACED BOTH SETS OF WIRES. THERE IS A SERIOUS PROBLEM WITH THE INSULATION ON MB ENGINE WIRES. THIS CAR HAD SAT IN A GARAGE MOST OF ITS' 15 YEARS AND THE INSULATION DETERIORATED BECAUSE MB USED A DEFECTIVE INSULATION AND SHOULD BE HELD ACCOUNTABLE. THIS CAR SOLD FOR OVER $64,000 NEW, AND FOR THE INSULATION TO DROP OFF THE ENGINE ELECTRICAL WIRES IS COMPELLING THAT MBUSA SHOULD HAVE TO RECALL AND REPAIR THEIR DEFECTS. *TR

I PURCHASED A 1993 MERCEDES BENZ-300SD THROUGH A LOCAL BUSINESS MAN IN COLUMBIA, SC WHO HAD THE CAR ON LEASE. I PAID THE LEASING COMPANY, MERCEDES CORPORATION FOR THE CAR. THIS CAR HAD TO HAVE A NEW MOTOR AT 46,000 MILES. I AM NOW TOLD THAT I MIGHT HAVE TO HAVE ANOTHER MOTOR. I HAVE HAD TO REPACE THE MOTOR FOR THE FAN THAT RUNS THE AIR/HEAT; REPLACE UNITS THAT CONTROLS THE FACTORY INSTALLED TELEPHONE AND NOW AM BEING TOLD THAT THE NEW MOTOR WILL COST FROM $10,000 TO $12,000. I AM HAVING PROVLEMS KEEPING FREON IN THE AIR CONDITIONER AND HAVE BEEN TOLD THAT THIS MIGHT COST UP TO $2,500; ALSO I WAS TOLD THAT I NEED BUSHINGS WHICH HAS BEEN ESTIMATED AT $2,000. I BELIEVE THAT I HAVE A LEMON SITUATION. I DID CONTACT THE COMPANY'S REPRESENTATIVE AND HE TELLS ME THAT THERE IS NOTHING HE CAN DO. I NEED YOUR HELP VERY DESPERATELY. WHATEVER YOU CAN DO, CONTACT THEM OR WHATEVER WILL BE GREATLY APPRECIATED. THE REPRESENTATIVE THAT I SPOKE WITH WAS RICE BYERLY.
