Mercedes C-Class Coupe reliability

The Mercedes C-Class finished 74th out of 100 cars overall in our Driver Power 2019 customer satisfaction survey. Owners praised its engine performance and in-car technology (sat-nav aside). However, one in five owners reported having an issue with their car, generally with the electrics or brakes.

Mercedes itself finished in 26th place overall in the survey of 30 manufacturers' cars – behind its main German rivals Audi (16th) and BMW (25th). This year, Mercedes also had the highest average share of owners reporting a fault with their car out of the German ‘big three’.


The C-Class Coupe comes with plenty of safety kit, some of which has worked its way down from the flagship Mercedes S-Class. That includes Attention Assist (which sounds an alarm if you need to take a rest) and Collision Prevention Assist (which can warn of an imminent collision).

A tyre-pressure monitor, automatic headlights, cruise control and a reversing camera are also included. The C-Class saloon achieved a five-star safety rating when it was crash-tested by Euro NCAP and there’s no reason to assume the coupe won’t do the same.
