53% of relevant owner complaints filed with NHTSA on the 2017 Mercedes-Benz C-Class are about the engine, transmission or fuel system. That is a model-level pattern, not bad luck.

Excludes 40 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 45%).
Does the 2017 Mercedes-Benz C-Class have engine problems?
Owner complaints say yes, as a model-year pattern. 113 of 213 relevant complaints filed with NHTSA about the 2017 Mercedes-Benz C-Class concern the engine, transmission or fuel system (53%), and the largest group is filed under engine (83). For comparison, the 2016 scores 51% and the 2018 scores 38%. On a test drive, check for stalling, loss of power, rough idle, oil consumption or a check-engine light. This describes the model year, not any one car: a well-maintained or already-repaired example can be fine, and a clean model year can still have a bad car in it.
