Is the Ux getting worse?
The fail rate rose 1.1 points to 3.8% from 2022 to 2025 while the median one tested aged 1 year, which is about what ageing alone predicts (1 point). Read it as the fleet getting older rather than the model changing.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 3,619 | 3 | 2.7% | 22.5% | |
| 2023 | 7,585 | 3 | 3.4% | 22.8% | |
| 2024 | 9,656 | 4 | 3.8% | 23.2% | |
| 2025 | 13,225 | 4 | 3.8% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical Ux at its test that year, and it is the number to watch: across the whole fleet each extra year of age adds roughly 1.9 points to the fail rate, so a model whose age and fail rate rise together is simply getting older.
The exact defects that fail it
Every failure item DVSA recorded against a Ux in 2025, counted by how many tests each one appeared on.
- 1Condition: has a cut in excess of the requirements deep enough to reach the ply or cords134 tests
- 2Condition: has ply or cords exposed75 tests
- 3Wipers: does not clear the windscreen effectively72 tests
- 4Tread depth: tread depth below requirements of 1.6mm64 tests
- 5Condition: has a bulge, caused by separation or partial failure of its structure40 tests
- 6Tyre pressure monitoring system: malfunctioning or obviously inoperative26 tests
- 7Condition: has a tear, caused by separation or partial failure of its structure22 tests
- 8Brake pads: less than 1.5 mm thick20 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical Ux collects 1.91 of them per test, and these are the ones that come up most. Treat it as the running-repairs list for the next year or two.

Questions
What is the Lexus Ux MOT pass rate?

By section, tyres appears in 68.6% of failures, visibility appears in 19.9% of failures, brakes appears in 7.5% of failures.
Does age change the odds?
Sharply. At 3 to 5 years old the fail rate was 3.5%; at 6-9 years it was 4.7%. The median Lexus Ux tested in 2025 was 4 years old with 29,766 miles.
Is the Lexus Ux getting less reliable?
The fail rate rose 1.1 points to 3.8% from 2022 to 2025 while the median one tested aged 1 year, which is about what ageing alone predicts (1 point). Read it as the fleet getting older rather than the model changing.
