2020 Kia Niro MOT pass rate: 91.7% (38,091 tests)
Is the 2020 Niro getting worse?
Pass rate of 2020-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 92.5% +1.7 vs same-age |
|
| 2024 | 92.1% +2.1 vs same-age |
|
| 2025 | 90.5% +1.6 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 2020 Niro?
