THE INSULATION ON THE WIRES DETERIORATE PREMATURELY ALLOWING THE WIRES TO SHORT OUT AND AFFECT AND HARM MOST OF THE COMPONENTS OF THE CAR. THE MANUFACTURER IS AWARE OF THE DEFECT, BUT REFUSES TO PROVIDE A SOLUTION OR TO ASSIST IN ANY WAY. THE ASR, & SRS SYSTEMS WERE DISABLED INTERMITTENTLY, THE CAR STALLED ON THE HIGHWAY AND THE ENGINE WOULD SURGE OCCASIONALLY. I BOUGHT THIS CAR USED, BUT IT WAS IN VERY GOOD CONDITION AND THIS MAJOR MANUFACTURING PROBLEM SHOULD NOT HAVE HAPPENED.
THE VEHICLE UNEXPECTEDLY DEVELOPED SUDDEN ACCELERATION WHEN SWITCHING FROM PARK TO REVERSE OR ANY OTHER GEAR.

I PURCHASED A 1994 SL600 ABOUT 6 MONTHS AGO WHICH HAD ONLY 56,000 MI ON IT. IT WAS SOLD TO ME AS A LIKE NEW AUTO.

I UNDERSTAND THIS IS A WELL KNOWN PROBLEM WITH MERCEDES 91-96 MODELS AND I WANT TO ADD MY NAME TO THE LISTS OF COMPLAINTS. *JB
