NHTSA Complaint #10484043 — 1994 MERCEDES BENZ E320

UNDER NORMAL DRIVING CONDITION ENGINE STARTED REVVING UP TO ABOUT 3500 RPM AS IF I PRESSED THE ACCELERATOR PEDAL. FREAKY EXPERIENCE BUT LUCKILY THE ROAD WASN'T TOO BUSY. I SLOWED DOWN TO THE SIDE OF THE ROAD (WAS DRIVING IN PORTLAND OREGON INNER CITY AREA) BY PRESSING THE BRAKES AND FLIPPING THE CAR INTO NEUTRAL BUT THE ENGINE KEPT REVVING UP AROUND 3000-4000RPM. WHEN I TURNED THE ENGINE OFF AND STARTED IT AGAIN, IT WASN'T SO BAD BUT THE ENGINE WAS STILL REVVING UP AND DOWN BY ITSELF BETWEEN ABOUT 750 AND 2000RPM. I ALSO NOTICED THAT THE CAR HAD GONE INTO - WHAT I LATER READ ON INTERNET TO BE CALLED - LIMP HOME MODE WHICH MADE IT VERY ANNOYING FOR ME TO DRIVE. RESEARCH ON INTERNET TELLS ME MY E320 WAGON WITH THE M104 ENGINE HAS A TYPE OF BIODEGRADABLE ENGINE WIRING HARNESS WHICH FALLS APART AND SHOULD BE REPLACED. I LOVE MY MERCEDES AND IT DRIVES BEAUTIFULLY, BUT THAT WIRING HARNESS PROBLEM MAKES IT A PROBLEMATIC CAR, AND DANGEROUS TOO. I AM NOT WILLING TO SPEND $1,500 ON A NEW HARNESS FROM THE DEALER, SINCE IT IS NOT A RESULT OF BAD MAINTENANCE, BUT MORE A DESIGN FLAW BY MERCEDES BENZ AG. THEY SHOULD TAKE THEIR RESPONSIBILITY AND DO A RECALL. SURPRISED THEY DIDN'T ALREADY DO THAT (DID THEY?) AS I CAN IMAGINE THE BIG DAMAGE TO THE MERCEDES BENZ NAME AND IMAGE IF SOMEBODY WERE TO END UP IN A FATAL CAR CRASH DUE TO A BIODEGRADABLE WIRING HARNESS PROBLEM. THANKS. *TR
