Gas Recirculation Valve (egr Valve) Problems of Mercedes Benz 500

I own a beautiful black 1995 s500 Mercedes Benz with 142,000 miles. As you know, the Mercedes Benz corporation knowingly installed a bio-degradable engine wire harness in models '91-'96. These engine wire harnesses, were purposely installed and designed to breakdown and disintegrate. Because of this flawed decision, I now face thousands of dollars in repair costs. After researching my vehicle's diagnosis, I discovered that mercedes corporation knew the horrific, detrimental hazards and immense financial costs owners inherited due to the bio-degradable material in their vehicles. I find it to be criminal and shameful that mercedes has never taken responsibility for this and have never notified potential buyers or owners of these vehicles of the hazards and expense. This is not a warranty issue. The entire car is at risk and so is my life. I am experiencing all kinds of malfunctions in my vehicle. When I went into mercedes to diagnose the problem, the wire harness and actuator were given as the cause and in need of immediate of replacement. Never once did mercedes inform me why the harness had failed. The wires have become unstable, causing shorts, malfunctions, smoke, and unreliable startup. Mercedes benz knew it from the start, and the national highway traffic safety administration also knows. Can you explain why Mercedes Benz has been allowed to get away with this obvious serious safety hazard that has the potential to cause unnecessary harm and death? after researching recalls, what I found left me disgusted and outraged. I am undertaking a campaign to get this out to the consumer. I wonder how many serious accidents, injuries even deaths have occurred because of this silence. Has NHTSA researched this? recall. . It?s the right thing to do!.
