The picture
Ux: a strong MOT record by UK norms
Across 7,858 MOT tests, the Ux returns 94.1% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a defective wiper blade. Windscreen damage and a seriously damaged tyre round out the top three. Average tested mileage sits at 26,466, 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 UX?
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 UX 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.
