2016 Mazda 3 MOT pass rate: 77.2% (31,393 tests)
Is the 2016 3 getting worse?
Pass rate of 2016-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 78.3% -4.9 vs same-age |
|
| 2024 | 77.3% -3.9 vs same-age |
|
| 2025 | 76.1% -3.5 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 2016 3?
