Yq50: middle-of-the-pack on first-time pass

Across 481 MOT tests, the Yq50 returns 70.7% first-time pass — below the UK fleet average. The single most-logged Major fail is brake pads worn below 1.0 mm. A stop-lamp out and a non-functioning shock absorber round out the top three. Average tested mileage sits at 15,536, which is the lens to read those failure rankings through. If you own one and the next test is close, the ranked list below is a sensible pre-test checklist.

Buying or keeping a Yq50?

Use the failure ranking as a pre-test checklist or a haggling lever. Treat the headline pass rate as a fleet-wide trend, not a guarantee on any individual car.

If you own a Yq50 and your last MOT looked nothing like the ranked failures above, that's normal — individual cars vary widely. The ranking shows the patterns testers flag most often across the country.
