NO ELEVATED SIGNAL
31%
39 of 126 relevant owner complaints are about the engine, transmission or fuel system
No elevated drivetrain complaint concentration in the available NHTSA records for the 2014 Mercedes-Benz C-Class. Engine, transmission and fuel system account for 31% of relevant complaints.
Better than 69% of the 1,789 model years we track (2010–2023).

Does the 2014 Mercedes-Benz C-Class have engine or transmission problems?
Not as a pattern, going by owner complaints. 39 of 126 relevant complaints filed with NHTSA about the 2014 Mercedes-Benz C-Class concern the engine, transmission or fuel system (31%). For comparison, the 2013 scores 31% and the 2015 scores 48%. 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.
Manufacturers fix things mid-generation. A bad year next to a clean one is common; the fix usually arrived in between.
