2019 Mercedes-Benz A MOT pass rate: 88.5% (125,677 tests)
Is the 2019 A getting worse?
Pass rate of 2019-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 89.3% -0.5 vs same-age |
|
| 2024 | 88.3% -0.0 vs same-age |
|
| 2025 | 87.7% +0.7 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.

FAQs
Is a 2019 Mercedes-Benz A reliable?

What mileage is too high for a 2019 A?
The median tested example shows 36,944 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.
