Wiring Problems of Mercedes Benz SL500

Car can hardly run--without stalling-hard to start mercedes dealer said to sell it because of wiring problems.

Car immediately stalled in the middle of the interstate. Driving vehicle and it began to stall. Was not able to even pull to side of the road. Was later able to jump start vehicle, however still had issues with stalling and no acceleration. Have been informed it is a "harness wiring issue".

Mercedes benz wiring harness problems 1993 ¿ 1995 car does not run correct.

This vehicle has a bio-degradable engine wiring harness. These harnesses are deteriorating. My vehicle suddenly lost all power, no power steering, no nothing on a freeway and I was lucky that I was not killed. Mercedes and the dealerships both know that vehicles with this type harness are death traps. I wonder how many people have already been killed, but wiring harness was never investigated as cause of accident. Why are you not taking action against mercedes? every vehicle still on the road should be recalled immediately if it has a bio-degradable wiring harness.

I have 1995 Sl500 last 8 years having electrical issues, related to wiring harness ,misfire ,steering pump,air pump and more. I am the first owner. All the wires are deteriorating,I thnik we need NHTSA to inspect these car manufacturers. If manufacturer installed the faulty wiring they should stand up and offer repairs at the mercedes dealers. Free. Regards.

My Mercedes Benz has a faulty electrical wiring in the command navigation unit in my Sl500. The vehicle has only 16,385 miles on it, though it is a 2005 model, and has been housed in a high-end garage with no trauma, no damage, and very little wear and tear. I purchased the car used about 6 weeks ago. Within the last 3 weeks the unit has gone from working intermittently to not working at all, simply providing a screen message: system unavailable. On March 5, 2012 I took my sl 500 the authorized dealer here, and contacted the service manager . After having my vehicle out of commission for two days, I read the diagnosis/repair report and was told this was not an error by me or the previous owner but something that happened somewhere in the manufacturing process, probably on the assembly line, as the sound amplifier had an internal electrical fault. Additionally, I have been to two independent Mercedes Benz dealers and they could not fix the problem. I've also learned that I cannot simply replace the stereo with a working model from any electrical store (like best buy or car stereo guys). It is my understanding that to replace the command unit would cost several thousand dollars. It is my belief that while the car is not within a typical five or six year warranty period (I just missed that period) it is clearly a car that has been well taken care of, barely driven, properly housed, and maintained. Given the findings from your authorized technicians, it seems that this is a problem that came with the car that would have surfaced at some point. Lucky me that it is surfacing now. I am hoping that the national highway traffic safety administration will contact mercedes about this faulty command unit. There are many other mercedes owners who have and are experiencing this electrical nightmare.

Had to replace the wiring harnesses in the car at a cost of $3500. 00. I now have to replace the wire harness again at a similar cost. There should be a recall for this nonsense.

I had a wiring harness fire in my vehicle a 1997 Mercedes Benz sl 500, it is due to a defect in the wire harness but Mercedes Benz is declining any involvement, I know of 129 other failures in like vehicles, it's costing me $10,000 to fix and I will not have my car back until July 2007. This needs to stop mercedes is deinying all involvment.
