Consumer Description

Engine code P052E has come on at 60k miles. After researching the problems this is a very common problem with the 2016 c300 that mercedes refuses to address. To add insult to injury the part needed to be replaced is a sensor worth 100 dollars but mercedes charges over $2500 because you need specialty tools to get to it. This is a very common problem with owners around 40-80k miles and has no cause other than faulty parts on Mercedes end.
