Is the 2010 Prius getting worse?
Pass rate of 2010-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 79.0% +11.0 vs same-age |
|
| 2024 | 78.7% +11.6 vs same-age |
|
| 2025 | 79.0% +12.2 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 2010 Prius?
