Is the Mustang Mach-E getting worse?
The fail rate rose 0.7 points to 8.1% from 2024 to 2025, against a falling rate across all cars.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2024 | 1,408 | — | 7.4% | 23.2% | |
| 2025 | 3,875 | — | 8.1% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical Mustang Mach-E 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 Mustang Mach-E in 2025, counted by how many tests each one appeared on.
- 1Tread depth: tread depth below requirements of 1.6mm155 tests
- 2Condition: has a cut in excess of the requirements deep enough to reach the ply or cords125 tests
- 3Condition: has ply or cords exposed86 tests
- 4Washers: provides insufficient washer liquid18 tests
- 5Washers: not working18 tests
- 6Tyre pressure monitoring system: malfunctioning or obviously inoperative17 tests
- 7Condition: buckle not functioning as intended16 tests
- 8Registration plates: does not conform to the specified requirements16 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical Mustang Mach-E collects 2.07 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.

- 2Brake discs: in such a condition that it is seriously weakened259 tests
- 3Non-component advisories: Child Seat fitted not allowing full inspection of adult belt188 tests
- 4Tread depth: tread pattern not visible over the whole tread area when minimum depth required is 1.0mm186 tests
