I own a 1993 mercedes benz 300e. I noticed a section of the wiring harness underneath my hood back against the firewall has begun to deteriorate. The protective plastic on the wiring harness is cracking, exposing wire. Looks like a fire hazard. My car has stalled several times for no apparent reason, possibly related to the wire problem.
When having the car serviced, the repair facility identified major deterioration of the engine wiring harness. They indicated that this could be a safety hazard, possibly causing a fire or losing all power to the vehicle while driving, making it very difficult to control the vehicle.
1993 mercedes benz 300e the wiring on the fuel injector system (as well as other areas of the harness) was replaced 5 years ago as defective now it is defective again. Mercedes benz refuses to accept responsibility for this issue. I have been told that the car is a potential safety hazard as the risk of fire is good. Mercedes appears to have used an insulation that is known for degradation and refuses to recall or care for the issue.
1993 mb 300e - wiring harness has begun to deteriorate causing the engine to stall and or not start. Stalling can occur while driving, thus losing all power to properly control the vehicle.
During a recent service of my vehicle at an authorized mercedes benz service center, I was informed that the insulation covering my wires were decomposing and the wires were exposed to the engine, hence creating a safety hazard for my family. Due to the severity of this problem, and the possible consequences if the wires caught on fire, I attempted to ascertain some clarity to what may have caused this problem. I then spoke to the mechanic, at which time he advised it was a material defect. During this brief discussion it was also revealed that this was not the first time he had observed this problem with 1993 300e class. Since, this appeared to be a habitual defect with this make and model; I asked if a recall had been issued to replace this decomposing wire harness. As a result, he replied "no." I then paid to replace my wire harness because of this extreme hazardous condition.
Mercedes 1993 300e wire harness engine wiring harness.(300e mercedes) cracked and brittle. Made with very poor materialsmade. This is a known problem with this year and make of mercedes. If you own one of these cars it is well known you will need to replace your harness. Mercedes knows of this problem and does nothing to help. I have a problem when my car will not pass smog until I replace mine. I think mercedes should a the least replace the part at no charge. Thousands of these cars were made and at a cost of over $500.00 per harness this is a lot of money from consumers. If you can help great. Thanks in advance for your help. Dave myers

I talked to several machanics and to dealer they told me that it is a common problem in this vehicle I am very suprised that it has never been recalled. It also causes the car to stall during take off and on the road while driving at highway speeds it will stall.something must be done before persons are killed or injured. Ts
My research indicate that this engine wiring harness problem is an ongoing issue for many mercedes benz, 300 e, and 300se cars with the twin cam engines made between the years of 1993-1995. Not only I am unable to have routine maintenance done, but I am told by the repair facility that this presents a safety problem, because there is a risk of fire associated with this defect.
No summary listed for above vehicle.
Engine cylinder head blew out, causing cooling leakage. Dealer has replaced engine cylinder head. Also replaced cruise control and ignition.
Brakes failed, resulting in extended stopping distance.
