ELECTRICAL WIRING HARNESS USING SOY BASED INSULATION DEGRADES THEREBY ALLOWING WIRES TO SPONTANEOUS AND/ OR INTERMITTENT SHORTS. THIS HAS CAUSED EXTREMELY DANGEROUS DRIVING SITUATIONS. VERY DIFFICULT TO TROUBLESHOOT UNLESS AND UNTIL ONE DISCOVERS INSULATION FAILURE. THIS HAS BEEN AND IS WIDELY KNOWN TO BE A PROBLEM WITH THIS ERA OF CARS. EXTREMELY BAD ENGINEERING DECISIONS WERE MADE. VERY SERIOUS AND POTENTIALLY DANGEROUS CONDITIONS. MERCEDES SHOULD BE HELD ACCOUNTABLE FOR MALFEASANT AND A RECALL SHOULD HAVE BEEN MADE. I BOUGHT THE CAR NEW; HAD SERVICE ONLY AT THE DEALER; WAS NEVER NOTIFIED OF THE PROBLEM. I HAVE OLDER CARS WITH MORE MILEAGE WHICH DO NOT HAVE THE PROBLEMS I HAVE WITH THE MERCEDES. VERY DISAPPOINTING. WILL NEVER BUY ANOTHER MERCEDES; ALL HYPE! *TR
