The Mercedes Benz E-420 electrical wiring was manufactured from biodegradable materials. After several years the insulation on the wiring harness began to deteriorate and fail. This lead to a cycle of increasingly severe electrical problems also lead to the safety on freeway where the other driver can not see my brake lights when I am braking due to this wiring issue.

My mb E300D's engine will cut off for no apparent reason. It started gradually just cutting off while sitting at an intersection or while slowing to a stop. Feeling it was anything from fuel to computer problems I took it to the shop on several occasions. They advised they could not find the problem and wanted to start replacing parts like relays. The problem came to a head while my wife was accelerating on an interstate ramp into traffic running 70mph. The car cut off causing near catastrophic accidents. This is of course unacceptable. Mercedes is acting like this is not a big problem. Upon searching the web, I found that this is a common problem -"cutting off for no apparent reason" and so far this Agency seems to have not done much to force Mercedes to correct this extremely hazardous condition. I can not keep driving the car until something breaks bad enough for Mercedes to find it. The wiring harness is the known culprit though Mercedes won't admit it.
