Pass rate of 2021-registered cars across recent test years:
| Test year | Pass rate | |

| 2025 | 87.5% -2.7 vs same-age |

FAQs
Is a 2021 Dacia Duster reliable?

What mileage is too high for a 2021 Duster?
The median tested example shows 26,261 miles. Anything far beyond that isn't automatically bad — a motorway-mile car with consistent service records often beats a low-mileage school-run car — but price accordingly and scrutinise the mileage trail for gaps or drops.
