Mercedes G-Class review - Reliability and safety

The latest G-Class was crash tested by Euro NCAP back in 2019, which is surprising considering its niche SUV status, but we’re happy to report that it earned a five-star rating. Thanks to its strong construction, the G-Class holds up well in the event of an impact, and adult occupants should fare well, with a 90 per cent score in this category.

Indeed, safety is one aspect of the G-Class that is much improved over the old model, with the new car benefiting from a host of safety and assistance systems, some of which are optional on the more everyday SUVs and saloons. 

For example, the Assistance package comprises blind spot assist and adaptive cruise control and would be an expensive option in other models. The G-Class also features active brake assist, multiple airbags, an i-Size child seat attachment system for the outer rear seats, and the obvious benefits of four-wheel drive.

Mercedes finished a disappointing 27th on the list of the best car manufacturers in our 2022 Driver Power customer satisfaction survey. Although the low volume G-Class hasn't appeared on the list of the best cars to own, Mercedes feature with the A-Class in 30th place out of 75 cars and the GLC SUV in 39th. The mechanicals in the new G-Class are well proven, with the V8 in the G 63 likely to enjoy a stress-free existence.

Warranty

While some volume car manufacturers offer five- and seven-year warranties, the G-Class is covered by a three-year guarantee, but at least there’s no mileage restriction. In comparison, Audi restricts its three-year warranty to 60,000 miles, although BMW’s cover is the same as Mercedes. Extended warranties are also available.

Servicing

Service and maintenance of the G-Class won’t be cheap, but you can lower the cost by using a ServiceCare package. For around £45 a month in the G 350 d or around £50 a month in the G 63, you can spread the cost of the servicing, with this example based on two services taken over two years, three services over three years, or four over four years.
