My 2012 mercedes e350 has oil contamination of the wiring harness. The oil has also damaged other components in the engine compartment including oxygen sensors; probes and ecu(computer) this is very expensive damage. Mercedes-benz had had recall for this problem in the past but the recall did not extend to the 2012 model year. They need to do another recall for this ongoing problem. This is a major safety hazard, as the car could stall in traffic without warning
2012 Mercedes-Benz E350 electrical complaints
Page 2 of 2: complaints 11 to 19 of 19, newest first, as owners wrote them.
The cam solenoid sensors are picking up oil, then it is being disbursed in to the electrical systems of the vehicle. It is flowing into, o2 sensors making the vehicle run in a full rich mode, it is reaching the computer system that runs the entire vehicle. This repair can cost upwards of $8000. I have done online research and it is a very common issue amongst many mercedes vehicles. The issue is a known problem, it was being repaired but mercedes stopped the repair. It comes from an internal issue, not a fail to maintain problem. I contacted mercedes, they say they don't know of the issue, but they did tell me, they know how to fix the problem for a cost of over $ 5000. To us. Online searches have resulted in many complaints by owners. Regular driving is a result of the issue. Now we can't drive out vehicle due to fear of the oil in the electrical lines reaching our cpu for the entire car, which will result several thousand more dollars on top of the repair cost. We have paid $ 800. At this point only to be told, do not drive the care or worse damage will occur. So we have a beautiful car that is collecting leaves and dust. I await your response, garyw. Smith. We contacted mercedes bens of raleigh nc, they are our contact point, they don;t know of an issue but know the cure for $5000. Plus dollars, hmmm, curious...

I started my car and it made a big loud noise from engine then I start getting all messages on screen that every things not inoperable. Even the gear shift was locked and the more I kept the car on the more noise was making. Its like I am pushing hard on gas panel.
I attempted to start the car and it would not crank. I called mercedes service and they sent service to jumpstart the car. The car finally started. As I began to drive, a warning light stating "power steering malfunction - check owners manual" came on. With considerable difficult, I avoided the curb in the parking lot and managed to get the car to a parking space. The "power steering malfunction" indicator would not come off even after turning the car off and on again. The car became undrivable.
