“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.

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. …”
