“My 1994 mercedes e420 was not starting properly (asr light coming on, on several occasions). Took it to mechanic who noticed electric tape on some connections, then later found out why. The wiring harness had deteriorated in multiple places. I was left stranded at a meeting in the pouring rain and could not get back to the hospital one evening.”

“I need a new head gasket to repair an oil leak. My mechanic told me that in the process of getting to the oil leak he had to take off the wiring harness upon which the harness disintegrated in his hand. I am very concerned the mb would you biodegradable material to manufacturer an important part of the vehicle. The replacement part is $1,000 and needs to be done now since the repairing the existing harness could cause a fire.”

I have since replaced wiring harness, plugs, but car is still surging not idling properly. Replaced intake air sensor, planning to replace idle actuator, and ovp relay. 153,000 miles I have spent 3000.00. My son was present and put out the fire and disconnected the battery. I could have lost my life. I have all old parts replaced.”

“1994 mercedes e320 was involved in the electrical wiring harness failure - insulation was cracking and peeling off and shorted out - this caused the throttle body and traction control to short out the main computer of the car. I have read other complaints from other mercedes owners telling me that mercedes does not have a recall. This cost me over $3,000 dollars in repairs and usage loss. Now, I am still chasing more electrical problems from the wiring harness defects.”
