Second-hand Mercedes GLB (Mk1, 2019-date) buying guide: high-quality second-hand seven-seat SUV

Diesels are claimed to deliver up to 50mpg and petrols up to 39mpg, but the AMG 35 is pegged at just 31mpg while also being in band 38 for insurance purposes; more common variants 24-31. in groups.

Only the GLB 200 and GLB 200d in AMG Line form fell below the £40k mark when new; This means most GLBs are subject to a luxury car tax premium of £410 for the first six years, resulting in road tax of £600 per year. The GLB comes with a three-year unlimited mileage warranty, although it can be extended for an extra fee.

Remembrances

26 recalls in four years is not a huge number; Sometimes there could be more than one problem for the same problem.

The first recall in September 2020 was due to water leaking into the forefoot cavities; Campaigns would follow later that year for oil leaks, middle row seats not latching, faulty rear spoiler and gearbox failures.

Faulty eCall software led to multiple recalls in 2021; Removal of spoilers and wheel well covers was behind other campaigns. Airbag issues have led to three recalls, while campaigns have also been launched for faulty crankshafts, suspension sensor failures, stability control issues, front axle corrosion and faulty steering software.

Driver Power owner satisfaction

The GLB didn’t feature in any of our New Car surveys, and there were only two Mercedes-Benz models this year: E-Class Mk5 ranks 27th and A-Class On the 31st. These are middling results, but even more disappointing is Mercedes’ 25th place in the Brands survey. This puts it at the bottom of the 32-strong table, where owners are underwhelmed by value, high operating costs and poor reliability.
