Mercedes B-Class review - Reliability and Safety

The B-Class is likely to score well in crash tests, but customer satisfaction levels could be higher

The B-Class hasn’t been tested by Euro NCAP, but the A-Class scored incredibly well in 2018. A 96 per cent rating for adult occupant safety was second only to the Volvo XC40 and on a par with the S60/V60.

Meanwhile, 91 per cent for child occupant safety was the joint-highest, while 92 per cent for pedestrian safety was the top mark. Even a score of 75 per cent for safety assist technologies does little to change our view that the B-Class will perform well when it is crash tested by Euro NCAP.

There’s a generous level of standard safety equipment, while a Driving Assistance pack can be added for £1,700. This package includes blind spot assist, emergency braking, steering assist, adaptive cruise control and route-based speed adjustment.

Mercedes finished a commendable third on the list of the most reliable car manufacturers in our 2018 Driver Power customer satisfaction survey. Although the previous B-Class didn’t feature on the list of the best cars to own, the C-Class finished 27th and the A-Class 56th out of 75 vehicles, which suggests there’s room for improvement.

Warranty

The B-Class is covered by a three-year/unlimited mileage warranty, which puts it on a par with the BMW 2 Series Active Tourer, but superior to Audi models, which are covered by three-year/60,000-mile warranties.

Servicing

The Mercedes Service Care package is available on the B-Class, which allows you to spread the cost of servicing. It costs £29 a month for both the Sport and AMG Line models.
