Is the Ux Electric getting worse?
The fail rate fell 0.3 points to 4.2% from 2024 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 | |
|---|---|---|---|---|---|
| 2024 | 860 | 3 | 4.5% | 23.2% | |
| 2025 | 1,325 | 4 | 4.2% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical Ux Electric 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 Electric 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 cords13 tests
- 2Tread depth: tread depth below requirements of 1.6mm12 tests
- 3Condition: has ply or cords exposed9 tests
- 4Wipers: does not clear the windscreen effectively4 tests
- 5Condition: buckle not functioning as intended3 tests
- 6Condition: has a bulge, caused by separation or partial failure of its structure3 tests
- 7Condition: has a tear, caused by separation or partial failure of its structure3 tests
- 8Tread depth: tread pattern not visible over the whole tread area when minimum depth required is 1.0mm2 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical Ux Electric collects 1.83 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.
