THE ENGINE/FUEL INJECTION WIRING HARNESS OF MY 1993 MERCEDES-BENZ 500E (64,000 MILES), HAS CRACKED INSULATION THROUGHOUT AND IS BEGINNING TO SHORT OUT, WITH THE RISK OF CAUSING DANGEROUS ENGINE MALFUNCTION, AND EVEN FIRE INSIDE MY ENGINE COMPARTMENT. I HAVE READ MANY REPORTS OF OTHER MERCEDES-BENZ CARS OF THE SAME AGE RANGE HAVING THE EXACT SAME ISSUE. THIS IS A KNOW ISSUE WITH MERCEDES THAT THEY REFUSE TO RECALL. *NM
