Mercedes Benz E320 loss of power problems

The vehicle will flood after being exposed to rain which has caused all sorts of electrical issues. I have read online where several others have filed lawsuits regarding E class Mercedes for similar issues. The car’s interior will take on water and since there’s several electrical components running along the floor board of the car they will become damaged and cause the car’s computers and electrical system to go crazy. I picked up my car from having the oil changed at a local service shop a few days after it was repaired and I was driving back home after the service pick up and the car completely lost power. I got out of the car and opened the trunk in which I had to do so by using the key inside of the key fob. When I opened the trunk, I noticed that there was a little bit of water in the trunk which led me to open the back door and to my surprise there was standing water behind the driver seat. I checked the driver floor and it was soaked as well. I had the car towed back to the shop where I had the oil changed and the owner did not have the available equipment to test the car. I dried the car out over the next several days and drove to a local Mercedes dealership where they told me to do a full diagnostic on the car it would cost upwards of $19k. Are you kidding me? Now I know from reading others stories that this isn’t an unknown issue. So, what do I do now…file an insurance claim? I guess that would be the next step but they’ll turn around and get the money right back out of me by raising my policy rates. This is terrible. My car is a 2004 E320 with just under 65k miles on it.

I coasted to brake down lane. I shifted back into park gear to reset, then back into drive gear to resume travel. This has happened two more times since. Can be a dangerous in heavy traffic roadways.

I was changing lanes and went to accelerate when the vehicle completely lost power. The cause of the loss of power is a plastic(yes plastic) rod that opens the intake to initiate turbo boost. The fact that his rod is made of plastic that can break so easily when you step on the gas pedal is dangerous. Mercedes benz is supposed to make a quality car that is very costly and it is shameful that it is made so shoddy creating a false sense of safety and quality. I am lucky to be alive and now have to fix this junk.

After the vehicle is restored, the owner started to experience signs of electrical mishap. At first, the overvoltage protection relay (ovp) shorted out and thus, the car couldn't be started. After replacing the ovp, $100, the car started fine and ended up being drivable but the owner noticed a very significant loss of power. It appears that there is misfire, in at least one of the cylinders leading from the ecu to the distributor. Owner still ended up going to a virginia state licensed inspection and emission. Where it failed inspection because of malfunctions in the brake light, as it appears that the reverse light doesn't come on. The air conditioning system was also faulty as it wouldn't turn on. Even though the owner failed inspection, the technician still proceeded to test the emissions of the car. Needless to say, the emissions failed because of hc (high carbon) which can be attributed to the misfiring of multiple cylinders, which is then associated to the lack of power the vehicle is experiencing. After the conclusion of the emissions, the technician attempted to start the vehicle and ended up having a small fire that was ignited in the exposed wires of the engine wiring harness that is close to the battery area. After the fire was put out, the car wouldn't be able to be started, assuming that the consumer would need a replacement for the engine wiring harness. Upon further research, this is a very common issue in the w124 chassis, m104 engine based e320. There apparently isn't any recall but action from the mercedes-benz USA should be imperative to create a safe environment for the owners of these particular car.

Vehicle was acting normally up to incident. Entering highway accelerating like normal and pulled out in front of tractor trailer when suddenly car had dramatic and frightening loss of power. Full throttle did nothing. Downshifting did nothing. With truck horns blaring and near collision, I pulled off the road. Restarting cleared the problem. Dramatic loss of power has occurred three more times with no warning nor check engine light. Now light comes on with egr out of range code. Discussing this with other mercedes diesel owners points towards soot clogged egr valve and soot clogged intake manifold. How such a problem could occur so frequently at such a low mileage with a company known for diesels is unknown.

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.
