MY 1996 MERCEDES SL500 WITH LESS THAN 55,000 MILES HAS CRUMBLING WIRE INSULATION ON THE ENGINE CONTROLS WHICH HAS RESULTED IN SHORTED WIRING IN THE ENGINE CONTROLS. THE POOR QUALITY OF THE INSULATION ON THE WIRES IS THE PROBLEM, YET THE CAR MAKER OR THE DEALER HAS NOT DONE A RECALL TO REPLACE THIS WIRING HARNESS FOR THIS SAFETY PROBLEM. I AM TOLD THE COST TO REPLACE ALL THE DEFECTIVE PARTS WILL BE THOUSANDS OF DOLLARS. THE CAR MUST BE REWIRED BEFORE IT CAN BE DRIVEN. *JB

MY VEHICLE SUDDENLY LOST ALL POWER, NO POWER STEERING, NO NOTHING ON A FREEWAY AND I WAS LUCKY THAT I WAS NOT KILLED. MERCEDES AND THE DEALERSHIPS BOTH KNOW THAT VEHICLES WITH THIS TYPE HARNESS ARE DEATH TRAPS. I WONDER HOW MANY PEOPLE HAVE ALREADY BEEN KILLED, BUT WIRING HARNESS WAS NEVER INVESTIGATED AS CAUSE OF ACCIDENT. WHY ARE YOU NOT TAKING ACTION AGAINST MERCEDES?
