Over the last couple of days, my car has displayed the "Engine Warning" message intermittently. I took this to the dealership for inspection and received the following fault code: P06DA00 - Inoperative Oil Pump Valve. For a car with low mileage, this could potentially be a car issue. The estimated total cost for labor and parts is over $5k. I think there are more cars affected.

There was smoke coming from from the engine compartment and spontaneous fire started while the car was at a stop light. The car was totally damaged. The car has less than 15000 miles driven. It is still under warranty. Information was sent to Mercedes-Benz USA with a certified mail and immediately via email from the dealership.

The towing company also told me that they had to tow another Benz not long ago from engine fire.

I was operating my vehicle on an open road, as I was proceeding to stop at the stop light the ligths on my dashboard began to dim.. suddenly without warning my vehicle completely shut down , no messages no warning lamps.. I turned the car back on it drove me up the block to my final destination and shut down again I called for a tow the next morning it arrived 24 hours later, the tow truck driver was able to start it and it immediately shut down and is now at a Mercedes dealership awaiting diagnostic test results. What a frightening experience.
Please see attached pdf. It concerns the trunk opening and closing mechanism which is supposed to signal when something is in the way before it closes. The trunk closed without warning on my head. Mercedes refuses to disconnect the trunk latch feature because I will not sign a release, which I will not do. See attached incident report filed with mb.
