THE BODY AND ENGINE HARNESS HAS BEEN FOUND TO BE CONTAINING MANY BARED WIRES BECAUSE THE WIRE COVERING IS DEFECTIVE. MY MERCEDES 600S SUDDENLY DECELERATED AND BECAUSE OF THIS I WAS REAR ENDED WHILE DRIVING ON THE FREEWAY. I FOUND OUT LATER AT A MECHANICAL SHOP THAT THE ENGINE WENT INTO SOMETHING CALLED "LIMPMODE" AND THIS CAUSED THE SUDDEN DECELERATION. I WAS FURTHER ADVISED THAT THIS ACTION WAS CAUSED BY A SHORT CIRCUIT IN ONE OF THE BARED WIRES OF THE ENGINE BODY HARNESS. UPON OBSERVATION THE WHOLE BODY WIRE HARNESS OF MANY WIRES EXHIBIT AN UNBELIEVABLE CONDITION WHERE YOU CAN VISUALLY OBSERVE THE WIRE'S COVERING DISINTEGRATING UNTIL NOTHING COVERS THE WIRES AND THEY ARE TOTALLY BARED. THE POSSIBLE RISK OF FIRE DUE TO THIS CONDITION IS WORTH AN IMMEDIATE RECALL BY MERCEDES IN ITSELF. WHY HAS THE NHTSA NOT ORDERED MERCEDES TO ADDRESS THIS SERIOUS PRODUCTION PROBLEM THAT I HAVE LEARNED IS COMMON TO HUNDREDS OF V-12 ENGINES FROM 1992-1995? DOES SOME ONE HAVE TO DIE IN A FIRE CAUSED BY THIS UNACCEPTABLE CAR ASSEMBLY MISTAKE? SURELY ONE CAN SURMISE THAT AS THESE CARS GET OLDER THE FREQUENCY AND RISK OF HUMAN DEATH OR INJURY INCREASES DAILY. MERCEDES IS HOPING THIS COMPLAINT AND RISK WILL ALL JUST "GO AWAY". THEY PROVERBIALLY SIT ON THEIR HANDS AND WILL ONLY ACT WHEN AN ORDER IS MADE BY NHTSA. SO OWNERS ARE PROTECTED. *TR
