Is the Logan getting worse?
The fail rate rose 5.9 points to 23.9% from 2022 to 2025 while the median one tested aged 3 years. Ageing alone would predict about 7.5 points, so it is holding up better than the fleet average for its age.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 15,361 | 6 | 18% | 22.5% | |
| 2023 | 15,677 | 7 | 20.8% | 22.8% | |
| 2024 | 13,268 | 8 | 22.7% | 23.2% | |
| 2025 | 13,726 | 9 | 23.9% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical Logan 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 Logan in 2025, counted by how many tests each one appeared on.
- 1Tread depth: tread depth below requirements of 1.6mm343 tests
- 2Ball joint: ball joint excessively worn333 tests
- 3Coil spring: fractured or broken238 tests
- 4Headlamp aim: too low226 tests
- 5Wipers: does not clear the windscreen effectively218 tests
- 6Horn: not working213 tests
- 7Brake pads: less than 1.5 mm thick206 tests
- 8Washers: provides insufficient washer liquid192 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical Logan collects 2.15 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 1.6mm2,493 tests
- 2Condition: has a tear, caused by separation or partial failure of its structure1,383 tests
- 3Brake discs: in such a condition that it is seriously weakened1,060 tests
- 4Brake pads: less than 1.5 mm thick742 tests
- 5Linkage pins and bushes: pin or bush excessively worn488 tests
