Selected complaints filed with NHTSA by 1995 Mercedes-Benz C Class owners, lightly cleaned up (personal details are redacted by NHTSA).
I own a 1995 c280 Mercedes, previously owned by my daughter for 5 years. The car always idled rough, occasionally backfires, lacks overall power. My daughter had it to the shop numerous times and they never really diagnosed the problem. Two days ago I started it, heard a loud pop and saw smoke coming out of the hood and smelled electrical wires burning. It had to be towed to the nearest Mercedes dealer. They want a total of $3300 to repair it. The issue is the wiring harness. I have read hundreds of consumer complaints regarding this issue. In 1993-1995 c280 models Mercedes tried a new insulation covering on the wires and it does not hold up. In fact, I have seen the result in numerous pictures of the condition the wires. The insulation just desintergrates. I read that up until a few years ago Mercedes was replacing them but then they just stopped. …
Failure of the engine wiring harness that caused smoking and fire, caught in time. Wiring insulation is faulty, made brittle due to engine heat. Also caused car to stall and not restart without costly repair.
My wife and I purchased a 1995 c280 Mercedes-Benz in August of 2002. The car had less than 20,000 miles and was garage kept. The car ran fine for a couple of years but began experiencing trouble with the car intermittently stalling out while driving, occasionally not starting, and ultimately leaving me stranded. In February of 2006 I took the car to a non dealer repair shop which specializes in Mercedes-Benz vehicles. After explaining the car's problems, the technician immediately said the wiring harnesses on this model and year are all defective. He opened the hood and showed me where the plastic coating had eroded from the wires. He rubbed the outside surface of a couple of wires to show me how the plastic insulation disintegrated in his fingers. I paid to have the wiring harness to be replaced at a cost of $2,354.76. Nobody was hurt nor did anyone die. …
Mercedes-Benz engine wiring harness defect enclosed, please find a list of reported complaints that I found on your very own national highway traffic safety administration (NHTSA) website concerning the chronic engine compartment wiring harness failure suffered by (at the least) 1992 through 1995 Mercedes Benz automobiles. This list is not, by any means, meant to be complete, as it only lists those reports that I was able to locate. Note that the first complaint on the list is mine. I am outraged at Mercedes-Benz' arrogant refusal to own up to, and take responsibility for, this extremely dangerous design and engineering defect. For the life of me (literally), I cannot understand why NHTSA has not investigated this dangerous situation, especially given the large number of complaints. I will not be satisfied with less than Mercedes' immediate rectification. …
Engine wiring harness failure on 1995 c 220 Mercedes - Benz. Had all engine wiring replaced at a cost of $500.00. Having so many electrical problems caused many parts to be changed that did not need to be changed. The car is in the shop now for over 9 months because mechanic can not figure why car continue having lost of power.before I found out about the bad wiring on this c 220 Benz,my car was almost hit by another car while trying to cross a busy highway. This could have tragic thank god they slowed down to let me cross. This is a very serious safety situation and something should be done about it asap before some get seriously hurt or receive death form this major problem. I'm over $4,000.00 in the hole and still no working c220 Mercedes Benz yet!
My well maintained '95 Mercedes-Benz c280 of which I am the single owner since new has a defective wiring harness. This could have been a very bad disaster as the car just lost it's power to drive while being driven...by my son, who just came off of I-95. He managed to get to safer ground and had to be towed. Mechanic(not a mbenz one) states never seeing anything like it as the wire coating is disintegrating into a powder like substance and baring all metal...caused it to ARC when first looking. Thank good fortune it didn't catch fire, explode or cause a bad accident. So if replaced by mbenz part cause it cannot be repaired....won't the same thing happen with it?
Wire insulation on my engine wiring harness has disintegrated exposing the internal wiring completely, especially in bent areas. This is a result of normal operation of the vehicle. As this happens the engine runs worse, problems associated include surging in idle, stumbling of engine upon initial acceleration and stalling or running engine. The only course of action is to replace the wiring harness with a "newly" purchased harness from Mercedes Benz. The only problem with that idea is I will be purchasing a wiring harness manufactured during roughly the same time the vehicle was in production that uses the same defective, advanced degrading wiring.
I own a 1995 c280 sedan with just over 55,000 miles. I have owned the car for approximately 1 year and was beginning to have the symptoms of the wiring harness failure described in many cases. It started after replacing the spark plugs and continued to get worse even after replacing all of the spark plug wires and connectors. The car back fired and started to run rough as if one or more plugs were misfiring. Usually after turning the car off and restarting the problems went away until the next time. I am concerned that this will start a fire or cause an accident due to loss of power and/or control.
The wiring harness on the engine degrades drastically to the point of the wires being naked. The harness used in all 1994-1996 cars were made of experimental insulation and so does not last and requires changing within g 50,000 miles. This causes the wires running through the engine to short and poses a significant fire hazard. The shorting of the harness burns the sensors causing further damage and causes misfires in the cylinders causing internal damage to engine components. Several tune ups were performed to try to correct this problem but later its was established that the whole harness was the culprit.
My 1995 Mercedes Benz c280 was running rough and stalled on the road. Brought vehicle to Mercedes dealer and found the engine wiring harness to be defective and deteriorating and crumbling cracked and exposed wires. My ignition portion failed where the wires connect to the spark plugs and high energy coils shorting out against the engine frame. Vehicle towed and technicians replaced engine harness parts plus labor $1,500. Repair bill. The harness is a manufactured dealer new item only no repair could be made as the entire wiring harness is defective and controls critical functions of the engine operation.
