Mercedes C-Class Cabriolet reliability

The Mercedes C-Class was rated average for reliability in our 2018 Driver Power owner satisfaction survey of cars currently on sale in the UK. Of the owners who responded, 18.1% reported experiencing a problem with their car at least once, with the electrics and brakes the most common culprit. It finished 27th overall, out of 75 cars in the survey.

Owners were least impressed by their car's running costs, while ride and handling weren't singled out for any particular praise, either. Impressive engines and safety features were the C-Class attributes that owners appreciate most warmly.

As a brand, Mercedes finished a disappointing 20th out of 26 brands in the survey.

Safety

Euro NCAP crash-tested the C-Class Cabriolet in 2017 and awarded it the full five stars. The car scored 89% in the adult occupant protection category, 79% for child occupant protection, 66% in the pedestrian category and 53% for safety assist.

There’s loads of standard safety equipment, including everything you’d expect such as stability control, anti-lock brakes, a host of airbags, ISOFIX child car seat mounting points for the rear seats and tyre pressure monitoring. There’s also automatic braking if the car detects an imminent collision, a pop-up bonnet to help improve pedestrian impact scores and a system for detecting drowsiness.
