2017 Fiat Auto Trail MOT pass rate: 94.1% (3,856 tests)
Is the 2017 Auto Trail getting worse?
Pass rate of 2017-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 94.8% +9.1 vs same-age |
|
| 2024 | 94.1% +10.2 vs same-age |
|
| 2025 | 93.3% +11.0 vs same-age |
The raw rate normally falls as cars age. The “vs same-age” figure compares this cohort with all UK cars registered in the same year, so normal ageing is not mistaken for a bad model year.

What mileage is too high for a 2017 Auto Trail?
