1993 Mercedes Benz S500

VEHICLE STALLED TO DEAD THREE TIME, ONE ON AN INTERSECTION. SYMPTONS STARTED WITH ROUGH IDLE, MISFIRING AND STALL. AFTER INSPECTION OF UPPER WIRING HARNESS (RECOMMENDED BY A FRIEND) THE CONCLUSION WAS BARE AND DESINTEGRATED WIRES CAUSING SHORT CIRCUITS EVERYWHERE IN THE CAR, PUTTING ME AND MY FAMILY AT RISK. IT IS AN EXPENSIVE REPAIR AND I CAN'T DRIVE THE CAR UNTIL MBUSA GIVES A SOLUTION WHICH I'VE HEARD THEY LOOK LIKE UNAWARE. I OWNED OTHER MERCEDES MODELS AND WE ALWAYS HEAR THAT THIS W140 SERIESWERE THE BEST CAR IN THE WORLD. BUT THIS ISSUE COULD HAVE COST MY LIFE.

WHEN THE ENGINE IS RUNNING AT IDLE, THE ENGINE WILL MISS IN A RANDOM MANNER UNTIL THERE IS A LOUD POP FROM THE RADIO SPEAKER, THE BATTERY LIGHT COMES ON, AND THE ENGINE STOPS. SOMETIMES THE ENGINE WILL CONTINUE TO RUN, CONTINUE TO MISS, UNTIL THE ENGINE EVENTUALLY STOPS. WHEN RUNNING AT SPEED AND THE ENGINE IS UNDER LOAD THERE IS A LOUD POP FROM THE RADIO SPEAKER, THE ENGINE MISSES, BUT THE ENGINE WILL KEEP RUNNING. THE MB DEALER AND AN INDEPENDENT SHOP BOTH INDICATED THE WIRING HARNESS IN THE ENGINE COMPARTMENT WAS DETERIORATED AND NEEDED TO BE REPLACED. AFTER THE HARNESS WAS REPLACED THE CAR OPERATED NORMALLY FOR ROUGHLY SIX MONTHS AND THEN STARTED FAILING IN THE SAME MANNER. ALL CONNECTORS WERE OPENED, CLEANED, AND RECONNECTED. THE CAR AGAIN OPERATED NORMALLY FOR ABOUT THREE MONTH AND HAVE STARTED FAILING IN THE SAME MANNER. AS OF WRITING THIS COMPLAINT, THE CAR IS NOT FUNCTIONING NORMALLY.
