3 Engine And Engine Cooling problem

Failure Date: 01/01/2024

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?.
