“I recently purchased a 1995 mercedes benz model sl600. Shortly after getting the car home the check engine light came on and a few days after that the asr warning light came on so I started to research what might be causing the problems. After extensive research I found an online website which had several articles about the possible causes. The website recommended that the wiring should be inspected for cracking and deterioration of the insulation. …”
NHTSA complaint #10394462, filed 2011-04, 79,500 miles“Engine wiring harness is crumbling like corn bread. It is cheaply made, I read that it has something to do with being recyclable. I have a 50 year old chevy with the original wiring harness and it is fine. I would never, never buy another mercedes benz again in my life and will warn everyone I know.”
NHTSA complaint #10178705, filed 2007-01, 110,000 miles“I bought a new mb 1995 sl320, about 18 months later I had a problem with it and was told its the engine wire harness which was replaced at no cost to me, however I have been having problem with the car ( idle and hesitation and bad smell from the exhaust ) for a while and finally I saw it , the wires have disintegrated inside the sleeves all wire are touching, some wire have no insulation at all just a copper wire, they knew of the problem or should have known then you see their commercials built like no other car. …”
NHTSA complaint #10348130, filed 2010-08, 140,000 miles“1995 sl600 with completely eroded engine wire harness. Almost all the insulation on the wires are gone leaving bare wires. This is completely ridiculous for a 100k car.”
NHTSA complaint #10379595, filed 2011-01, 69,300 miles“I own a 1995 sl600 with just 42k miles and in pristine condition. The asr system periodically and randomly engaged, even when slippery road conditions were not present. This occurred again 9/22/07 and the engine would not run. The mb dealer inspected the problem and discovered multiple error codes. The cause of this was due to the wiring harness(s) basically melting due to engine compartment heat. Luckily the car did not detonate. However, this is a documeted typical failure. The estimated cost to repair is $6,000 and that is just for the harness(s) to be replaced. …”
