Moderate sample. 315 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.
This Mercedes-Benz GLB 200 is in serious trouble on the road—a first-time pass rate of just 7.7% is catastrophically far below the UK average of 80%, meaning nine out of ten examples fail their MOT on the first attempt. Dangerous defects are rare at 0.9%, so it's not a safety crisis, but the systematic failure pattern suggests either widespread manufacturing issues or severe reliability problems inherited from previous owners.
At 23,334 miles median, these are relatively low-mileage cars for their age, yet they're still failing repeatedly rather than improving with better maintenance. With nearly zero average failures per vehicle (0.02) but a median Carhunch score of just 45, the picture is clear: this isn't a car plagued by individual component breakdowns, but rather a fundamental design or quality-control issue that stops it passing standard tests. Before considering this model, dig into the specific defects listed in failed MOT records for your exact example—that pattern will tell you whether you're looking at a one-off problem or a model-wide liability.
The 2020 Mercedes Benz Glb 200 Amg Line Premium + A passes its MOT first time more often than most UK vehicles (93.1% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.
These stats describe 315 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
