NHTSA Complaint #11476971 — 2014 MERCEDES-BENZ C250

The Cam Shaft and the boost pressure need to be replaced immediately. I took my car to a Mercedes Benz dealership in Long Island, NY for a regular oil change (nothing was wrong with my car when it went in for the oil change). When they gave me back my car I literally got 1 and half blocks from the dealership and my car was jerking violently and the check engine light came on and has not gone off since that day. I took the car right back to the dealership and of course they are saying they did nothing to make this happen and are refusing to cover the repairs for the Cam Shaft and boost pressure to make my car run correctly again. This is a dangerous car to drive now because due to this same problem the car has random issues accelerating and has put me in dangerous situations while driving on the highway and on the street. The interesting part is Mercedes Benz knows that this is a serious issue with this car because I was told that by the people that work at the dealership that Mercedes is covering the full repairs for what my car is going through but they are only doing it for people who's cars are under 120,000 miles. My car is at 133,000 miles and they are refusing to cover the repairs for me. My complaint number with Mercedes Benz customer service is 2-29420067413. They are not being helpful because they told me that every Mercedes dealership in the United States is independently owned besides the one in Manhattan NY. They are telling me that even though they are the manufacturer each dealership makes their own decisions. This is absolutely absurd and my car is dangerous to drive at this point. They want $5,000 and counting from me to repair my car for something that they messed up on and that they know is a known issue. Please help me get this resolved. Thank You
