Is the 2017 Forester getting worse?
Pass rate of 2017-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 87.9% +2.1 vs same-age |
|
| 2024 | 86.0% +2.1 vs same-age |

FAQs
Is a 2017 Subaru Forester reliable?
2017-registered examples passed 85.5% of their MOT tests (2,688 tests, 2023–2025), +1.4 points versus all UK cars registered in the same year. At roughly 9 years old with a median 52,817 miles, condition now varies car by car — always check the individual MOT history.
What mileage is too high for a 2017 Forester?
The median tested example shows 52,817 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.
Should I buy the petrol or diesel 2017 Forester?
In this cohort petrols pass 87.4% of tests against 81.8% for diesels. Mileage and use can explain part of that gap, so treat it as a reason to inspect DPF and emissions history, not a fuel-type verdict.
