In 2025, 53,632 Ford B-Max cars had a regular MOT in Great Britain. 68% passed first time, compared with 70% for all cars of the same ages, which makes the B-Max about average. Adjusted for age, it ranks 161 of the 217 most-tested car models.
That comparison matters: older cars fail more often, so a raw pass rate flatters models that are mostly young. We compare each model against every car on the road at the same age.
Pass rate by age
At 7 years old, 67% of B-Maxs passed first time (all cars that age: 81%). By 13 years, that figure is 62% (all cars: 63%). It trails the average car at most ages, most noticeably at 7 years (14 points behind).

What fails most on a Ford B-Max
The area that lets the B-Max down most, relative to other cars, is lights and electrics: 21.3% of tests failed on it, 1.3 times the rate for the average car. It does comparatively well on body and structure and brakes.

| The aim of a headlamp is not within limits laid down in the requirements | Lights and electrics | 3.2% |
| Wiper blade missing or obviously not clearing the windscreen | Visibility | 3.0% |
| A tyre seriously damaged | Tyres | 2.7% |
What to check when buying a used B-Max
Based on where the B-Max fails more often than other cars, these are the checks worth making before you buy:
- Lights and electrics: Walk round with the lights on: headlights (dipped and main), indicators, brake lights, number-plate and fog lights. Bulbs are cheap, but a seller who hasn’t noticed one out may have missed more. Repair guide
- Tyres: Check tread across the whole width (uneven wear hints at alignment or suspension faults), and look for cuts, bulges and mismatched brands. Repair guide
- Visibility: Check the windscreen for chips in the driver’s view, the wipers for smearing and the washers for working jets. Repair guide
Then check the individual car: its own MOT history will show whether it follows the pattern. A car with repeated advisories in the same weak area is more likely to fail its next test.
