The picture
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.

Year-band analysis
First-time MOT pass rate split by registration band. Pass rates barely move across bands here, so the year you buy Lexus UX makes little measurable difference to MOT outcomes.
Best band to buy
95.1%
2021+ registration
the 2021-on band climbs to 95.1% — a 1.0-point improvement. Tests in this band average 23,143 miles — roughly 10K miles fewer on the clock than the older band. Failures here are mostly wear items: blade defective, damaged but not adversely affecting driver's view — the structural issues that drag down older examples don't appear in the top-10 for this band. Post-2020 examples are early in their MOT life and generally show the cleanest records.
Band to be cautious about
94.1%
2018–2020 registration
On the 2018–2020 band, the data shows a 94.1% pass rate against a fleet average of 95.1% on the newer band. The main culprits logged at test: blade defective, damaged but not adversely affecting driver's view, and has a cut in excess of the…. Average mileage on test for this band is 32,741 miles — high-mileage wear items are a recurring theme.
Best band to buy: 2021+ (95.1% first-time pass). Worst band to avoid: 2018-2020 (94.1% pass). That's a 1.0-point spread across 12,560 older tests and 7,273 newer ones — year of build makes a material difference on this model.

Recall history
The UX has 1 official UK vehicle recall covering defect details, remedies, and affected build dates.
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 an 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.
