I bought this car new in 2013. I maintained it at the dealer as per MB recommendations. Last service was in August 2023. Currently had 42K miles on it. Two weeks ago 2 unknown to me lights came on and I took it to the dealer. The diagnosis was total failure due to oil leaking into the computer system. Second problem was water in the subfloor affecting sensors. Coons Mercedes in Catonsville, MD has all records. I was told that the oil leak was not detected because it was internal and due to an engine design. I was informed that there are many others stuck with this problem. I was informed that I was driving a car that could become suddenly uncontrollable. This was very scary. I was told I needed a new car. My insurance company inspected it and determined it was a total loss. I complained to MB headquarters and HQ in Stuttgart. I told them that they need to buy a new car for me. I have not heard from them. If MB know that there is an engine flaw why are they putting peoples' lives at risk?

2013 C300 4matic luxury model. 1/26 - my engine stop while waiting for traffic light. (2nd trip of the day) it's not eco stop/start kind of stop. The car won't start when I release my brake and all the warning lights at dash were on. 1/29 - today when I started the car this morning the engine stop 1-2 seconds after I started it. (2nd trip of the day) all warning light at dash were on. I took out my key then plug in to start it again. This time engine started, but both engine and car shake looks like it?S going to stop. I wait for 6-7 seconds then stop the car. I wait for another 30 seconds then start my car again and this time is normal. Don't want to see engine to stop while driving. Just made an appointment for dealer to check next week. Please help investigate this issue also.
