Is the Auto Trail getting worse?
The fail rate rose 2.5 points to 7.9% from 2022 to 2025 while the median one tested aged 3 years. Ageing alone would predict about 6.6 points, so it is holding up better than the fleet average for its age.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 8,764 | 5 | 5.4% | 22.5% | |
| 2023 | 9,291 | 6 | 6.3% | 22.8% | |
| 2024 | 7,807 | 7 | 7% | 23.2% | |
| 2025 | 8,876 | 8 | 7.9% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical Auto Trail 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 Auto Trail in 2025, counted by how many tests each one appeared on.

What wears out first
Advisories are the tester flagging wear that is still legal. A typical Auto Trail collects 2.01 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.
