Is the D-Max getting worse?
The fail rate rose 4.5 points to 24.6% from 2022 to 2025, against a rising rate across all cars.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 26,525 | 6 | 20.1% | 22.5% | |
| 2023 | 28,155 | 6 | 21.5% | 22.8% | |

Fail rate is first attempts at class 4 tests. Median age is the age of a typical D-Max 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 D-Max in 2025, counted by how many tests each one appeared on.
- 1Shock absorbers: has an excessively worn bush1,242 tests
- 2Rear fog lamp: not working1,240 tests
- 3Ball joint: ball joint excessively worn1,007 tests
- 4Exhaust system: has a major leak of exhaust gases914 tests
- 5Position lamp: not working770 tests
- 6Rigid brake pipes: excessively corroded690 tests
- 7Wipers: does not clear the windscreen effectively650 tests
- 8Wheel bearings: has excessive play617 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical D-Max collects 2.74 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.
