This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
Engine wiring harness insulation falling off - copper wires exposed and may result in short and engine failure at highway speeds - could result in injury or death. Consumer stated wiring is defective and that Mercedes has been aware of the nature of the defect for many years.
On this 1995 Mercedes E320, would not pass emissions, took to dealer, was told the engine compartment wiring harness needed to be replaced, at a cost of $1500. The wiring harness was crumbling everywhere. I checked online and it is a very common problem with all E20. I checked no recall for this problem. This is totally a manufacturing problem, the coating to the wiring has disintegrated and it is unsafe to drive these cars. I have spent over $2,000 to try to get this car to pass emissions, it fails so bad I cant even get a waiver.
Purchased in late spring 2014. Fire in right door electrical wiring mid June. Stall at red light in mid July. Stall on highway, stop and go traffic in mid September. And stall at a red light Sept. 27, 2014. Bought it, it had 107,000miles.
I dropped off my car at auto shop due to my car starting rough, the ac and fan cut off, and check engine light came on. I was also concerned that this could be the wire harness as I had read about problem on the internet, and had discussed possible issue with various Mercedes mechanics. I was told that Mercedes Benz had installed bio degradable wire harness that were resulting in premature deterioration. While my car was in the service bay at S the automotive shop my engine wire harness caught on fire! the mechanic was able to put the fire out before entire car and his shop caught on fire. I have asked him to retain harness for evidence, he said harness is in pieces due to extreme heat of this electrical fire. I am so thankful that the car caught on fire at the shop, or my entire family could have been killed. I say this as my electric locks were messed up, and sometimes I had to wait up to a minute or more to open the car doors and trunk, and also to lock my vehicle due to some sort of short. We could have all burned to death if the car caught on fire while driving on the highway, and we could not of exited the vehicle. This is a serious safety issue, and there needs to be a recall. There are over 700 complaints, along with dozens of fire complaints, regarding engine wiring harness defect on Mercedes Benz built between 1991-1997 with the National Highway Traffic Safety Administration. How many safety reports, engine harness fires, and possible harness fires resulting in death does it take for action in the form of a recall by Mercedes Benz and the NHTSA? this is not a matter "if" these wire harness with fail, but when and how. I would like to request an investigation regarding my engine wiring harness that failed and caught on fire, and resulting damage to my car.
Wiring harness has same problem as noted by other owners-started with wiring to mas melting. I rewired that-drove car another year with small electrical problems blowing fuses without finding cause-drove car to work one day, ran fine, came out to go home and it had a miss. Removed cover over injectors and found all the wiring was bare.this is a common problem with mbs and they should have a recall.
The electrical insulation on the engine wiring harness failed and cause the engine to misfire. My concern is either an electrical short could cause a fire or computer failure.
Wiring harness deterioration due to manufacturer defect. Wiring harness insulation deteriorates leading to other component failures, and compromised safety, fire hazard, drivability compromised.
The wires in the wiring harness connecting to the coils for the fuel injection system are disintegrating. Currently this is causing the car to loose power, run rough, only 2-4 cylinders are firing. My mechanic said he found on the web that this is happening a lot to Mercedes cars made during the time period my car was made but Mercedes never issued a recall for this huge problem. My cost to fix this problem was estimated at $3200 or more depending on how much of the wiring system has disintegrated and what other systems are affected. I called Mercedes on howe ave in sacramento and after checking my VIN number said my car has never been recalled for this problem or any other problems.
The car began to idle rough months before, it completely stopped. I thought this was just a mass airflow sensor, but after getting that fixed I didn't know what it was. A few months later, the car stopped in the middle of the road. It could have ended in a crash but thankfully I was on a road with fairly light traffic. Upon inspection, the wiring harness on my '95 E320 completely was wearing away, specifically around the ignition coils. I'm ashamed of Mercedes for not recalling this problem, as it (I have found out after reading) is an infamous problem with mb from 1993-96. I hope that they sort this out so no one gets in a crash, or worse.
I have multiple wiring problems with this car. Faulty tachometer goes on and off by it self. Faulty ac wires isolation is destroyed, faulty glow plug light goes on and off by it self. This car has wiring problems like many other W124.
I have two Mercedes Benz W124 cars. Both cars have had the wiring harness failure and that destroyed many very expensive electronic components on the cars. 1993 300E 4 door sedan, wiring harness failure and destroy many things very expensive on the car 1995 E320 cabriolet rare collectors convertible made in 1994 and 1995 only! please send me two forms to fill out.
The contact owns a 1995 Mercedes E-320. While having the vehicle repaired by an independent mechanic for unrelated failures, the contact was advised to replace the wiring harness because the insulation on the wires was deteriorating. The contact was also informed that the deterioration of the insulation could lead to engine fires as well as the vehicle stalling. The vehicle was not repaired. The failure and current mileage was 156,000. The VIN was not available.
1995 Mercedes Benz E320 engine wiring harness and throttle actuator wiring. The wire insulation used on the engine wiring harness and the throttle actuator in my car has badly degraded! this causes all kinds of shorts within the electronics of the vehicle and problems with the electric throttle system in this car. The problems with the throttle actuator caused my car to go in and out of limp mode(reduced power) while I was driving. This caused my car to accelerate very quickly and nearly caused an accident!. this problem needs to be a manufacturers recall before somebody's throttle gets stuck and they get hurt or before their car burns.
1995 Mercedes E320 wagon. The engine wire harness has disintegrated leaving exposed wires in engine bay that could cause fire. Also causes acceleration and idle problems along with various intermittent warning lights.
The whole engine wiring harness that runs all over my engine is defective. The insulation around the wiring literally fell apart, as everyone else on here described as breaking into brittle pieces and disintegrating. The car shut off completely in the middle of the highway. A service advisor at a local dealership knows about it and says they won't fix it because "the government hasn't ordered them to recall it" and went on to give me a quote for nearly $2,000. Now my car is stuck in a shop with all the bare wires showing and the decayed insulation in pieces all over the floor. I don't know what to do. I did a lot of research and apparently it is a defect in every 1995 E320 manufactured in the us. A lot of people say it also affects 1993-1994, as well as other models with the same engine. I'm the original owner, bought the car new from the dealership in 1995. It only has 57,533 miles on it and has always been garage kept.
The contact owns a 1995 Mercedes Benz E320. The contact stated that she had just left a repair shop where a bulb was replaced when she was driving at approximately 30 mph and smelled burning wires. She took her foot off the accelerator pedal and the vehicle suddenly hesitated. She turned around to go back to the repair shop but noticed that the vehicle had caught fire. She called the fire department and the fire was put out. She was not sure if a fire report was filed. The contact then drove back to the repair shop where the vehicle was repaired. The vehicle caught fire again after leaving the repair shop. The contact called the fire department again and the fire was extinguished. Once again, she was not sure if a fire report was filed. The vehicle was returned to the same repair shop where the contact was informed that the failure was caused by an electrical problem and a brake failure. The contact did not feel safe driving the vehicle. The failure mileage was 143,728. The current mileage was approximately 144,000.
1995 Mercedes Benz E 320, deteriorating wiring harness in the engine compartment. I believe to be causing my check engine light to come on even after replacing the mass air sensor and 02 sensor. This problem was noticed over 10 years ago but are unaware of the complaints other owners have. Now the harness is brittle and in constant repair. I tend to think that this kind of components should last the life of the vehicle.
The insulation on the wires inside the wiring harness from ECU to the rest of the car has become brittle and is falling off, allowing wires within the harness to short out to each other. This can destroy various sensors and perhaps the engine control computer itself. Although my mechanic has seen many 1995 Mercedes Benz cars with this defect, mbusa claims to not have any knowledge of this defect. I am replacing the wiring harness at a cost of approx $1600. The original wiring harness is available for inspection. Shorting together of the wires in the wiring harness may cause fires and the sudden loss of control of vehicle. I request that NHTSA investigate this seemingly common problem that Mercedes Benz claims not to have heard of.
