2018 Fiat 500L MOT pass rate: 76.5% (1,776 tests)
Is the 2018 500L getting worse?
Pass rate of 2018-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 81.2% -6.9 vs same-age |
|
| 2024 | 79.2% -7.0 vs same-age |
|
| 2025 | 69.1% -15.7 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 2018 500L?
