Mercedes Benz engine problems

Owners have filed 3,487 complaints with NHTSA about the engine on Mercedes Benz vehicles — 10% of everything reported about the brand, across 256 models. The model that accounts for most of them is the Mercedes Benz C300, worst in 2015.

These are raw counts. A model that sold in millions appears near the top for that reason alone — the grade never compares one model with another.
