Is the E-Niro getting worse?
The fail rate rose 4 points to 8.7% from 2022 to 2025, against a rising rate across all cars.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 2,165 | — | 4.7% | 22.5% | |
| 2023 | 14,136 | — | 6.3% | 22.8% | |
| 2024 | 23,891 | — | 8% | 23.2% | |
| 2025 | 36,019 | — | 8.7% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical E-Niro 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 E-Niro in 2025, counted by how many tests each one appeared on.
- 1Condition: has ply or cords exposed711 tests
- 2Condition: has a cut in excess of the requirements deep enough to reach the ply or cords673 tests
- 3Tread depth: tread depth below requirements of 1.6mm622 tests
- 4Wipers: does not clear the windscreen effectively601 tests
- 5Tyre pressure monitoring system: malfunctioning or obviously inoperative87 tests
- 6Washers: not working76 tests
- 7Service brake performance: efficiency below requirements74 tests
- 8Condition: has a bulge, caused by separation or partial failure of its structure70 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical E-Niro collects 1.85 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.
- 1Tread depth: tread depth below requirements of 1.6mm5,684 tests
- 2Brake discs: in such a condition that it is seriously weakened1,577 tests
- 3Condition: has a tear, caused by separation or partial failure of its structure1,272 tests
- 4Tread depth: tread pattern not visible over the whole tread area when minimum depth required is 1.0mm995 tests
- 5Condition: has a cut in excess of the requirements deep enough to reach the ply or cords788 tests
- 6Non-component advisories: Child Seat fitted not allowing full inspection of adult belt781 tests
