ENGINE STOP RUNNING WHILE DRIVING. CAR WAS TOWED TO MECHANIC WHO FOUND THAT ENGINE HARNESS WAS COMPLETELY DEGRADED AND WIRES WERE TOUCHING EACH OTHER THANK GOD IT DID NOT CATCH FIRE INSTEAD IT SHUT OFF. MY MECHANIC SAYS THAT HE SEES THIS ALOT AND THAT THIS SHOULD NOT HAPPEN TO A VEHICLE LIKE THIS. *JS
MY MECHANIC REPORTED THAT THE INSULATION IS CRACKING AND PEELING AT THE HARNESS, AND THAT IT IS DANGER OF CAUSING SERIOUS ELECTRICAL DAMAGE THROUGHOUT THE SYSTEM, ENTAILING MALFUNCTION OF COMPUTERS, CRUISE CONTROL, BRAKE AND OTHER SYSTEMS, AS WELL AS SEVERE ENGINE DAMAGE, INCLUDING ENDANGERING PASSENGERS IN THE EVENT FAILURE OCCURS WHILE DRIVING. I HAVE BEEN ADVISED THAT THE PROBLEM IS OF POOR QUALITY INSULATION IS ENDEMIC AMONG 1993-96 MBZ MODELS. I OBSERVED THE HARNESS MYSELF, AND THE INSULATION ON ALL WIRES ENTERING THE HARNESS IS CRACKED AND WIRES ARE EITHER ACTUALLY EXPOSED OR ON THE VERGE OF EXPOSURE. THE CONDITION IS DANGEROUS, AND I AM ADVISED THAT THE LOCAL MBZ DEALER(RAB) DID OBTAIN AUTHORIZATION FROM MBZ IN ONE CASE TO REPLACE A SIMILARLY AFFECTED HARNESS WITH MBZ PROVIDING THE PARTS,BUT NOT THE LABOR. IT IS APPEARS THAT THE DEFECT IS DANGEROUS AND WIDESPREAD, AND PERHAPS IS SYMPTOMATIC, AS I NOTE THAT THERE IS ANOTHER COMPLAINT IN YOUR RECORDS ABOUT THE ELECTRICAL SYSTEM IN SAME YEARS MODEL. *TS *JB ***DIMSII IVOQ ENTRY POSTED AFTER 12-12-02 CUT OVER TO ARTEMIS***762213
