Mercedes GLC review - Reliability and Safety

A huge amount of safety kit and strong Euro NCAP results offer great protection

In our 2019 Driver Power customer satisfaction survey, the GLC finished 61st out of 100 cars, with some concerning feedback for buyers to reflect on. Plus points included a high-quality, well-styled interior, with decent interior space and a great stereo sytem. However, reliability was a key issue as was high levels of road noise and running costs, while a surprising 44% of owners had experienced a fault with their car - including engine, electrics and interior problems.

You’d expect a premium brand’s garages to rank well, but Mercedes dealerships only tend to place in the lower half of the Driver Power dealer survey. Again, Mercedes is fighting with BMW in a similar position, with both well behind rival premium brands such as Volvo and Jaguar, and especially Lexus, which is a frequent chart topper.

All GLCs get ESP with Dynamic Cornering Assist, Crosswind Assist and Collision Prevention Assist Plus. Of course, like many new cars there’s a host of airbags, seatbelt reminders and ABS brakes, while buyers can also spec Distronic Plus with Steering Assist and Stop&Go Pilot. This allows drivers a degree of autonomy – with the car able to accelerate, steer and brake of its own accord in busy motorway traffic.

Thanks to its arsenal of safety kit, the GLC earned a five-star Euro NCAP rating in 2015, while a 95 per cent score for adult occupant protection, and an 89 per cent score for child safety, mean the GLC is a very safe place to be.

Warranty

Every GLC comes with a three-year/unlimited mileage warranty, which is fairly average for the class, although some rivals put a mileage cap on their warranty coverage.

Servicing

Mercedes GLC buyers can make a one-off payment to cover a list of service items, with servicing plans available from one year right up to four years.
