Hello, recently started having problems with my asr system on my 1993 mb 400e and the service writer told me my wiring harness was faulty,cracked and was turning to dust ! He said if I didn't fix it would cause me serious problems - even possibly an engine fire ! He told me cost to replace the wire harness + labor would be about $ 1080.00. Come to find out tens of thousands of people have this problem. Why don't you folks get mercedes to issue a safety recall !! How many people have to die or get burned alive before you help the public that your supposed to protect !! Please help us--thanks for your time.
Engine wiring harness was deteriorated completely causing engine problems,stalling in traffic. It was corrected by buying a new wiring harness. The old part was kept. It is understood by me that the insulation used was biodegradable.
The design and location of the spark plugs causes a very serious safety hazard. In order to replace or inspect the plugs wire harness needed to be unbolted and pushed backwards, wire harness shouldn't be moved. Wire harness shorted out, causing a short out of all components in that circuit.
The vehicle caught fire after mildly rearending another vehicle.
Vehicle intermittently surges at speeds of 10-20 MPH.
Brake and rotor wear out at 4,000 miles. Tt
