The Mercedes C-Class has good safety credentials and is generally well received by owners. Lots of safety equipment is included as standard and there’s scope to add advanced driving aids, too.

Mercedes C350e reliability

The Mercedes C-Class was rated average for reliability in our 2017 Driver Power owner satisfaction survey of cars currently on sale in the UK. Of the owners who responded, 12.9% reported experiencing a problem with their car at least once. Not a lot is known about the reliability of the plug-in hybrid hardware used in the C350e because it’s such a new model, but we fully expect Mercedes to have tested it extensively in harsh conditions.


The Mercedes C-Class scored the full five stars when it was crash-tested by Euro NCAP in 2014, with an impressive 92% result for adult occupant protection. While this was a standard model, we’d expect the plug-in hybrid to be just as safe in a collision.

Lots of safety kit is standard, including a system that can automatically apply the brakes if an imminent collision is detected. Fitting the Driving Assistance pack increases the number of active systems designed to prevent a crash on the motorway, around town or when parking.
