2018 Jeep Compass MOT pass rate: 80.9% (7,020 tests)
Is the 2018 Compass getting worse?
Pass rate of 2018-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 84.4% -3.7 vs same-age |
|
| 2024 | 80.7% -5.5 vs same-age |
|
| 2025 | 77.7% -7.1 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 2018 Jeep Compass reliable?
2018-registered examples passed 80.9% of their MOT tests (7,020 tests, 2023–2025), -5.4 points versus all UK cars registered in the same year. At roughly 8 years old with a median 43,352 miles, condition now varies car by car — always check the individual MOT history.
What mileage is too high for a 2018 Compass?
The median tested example shows 43,352 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 2018 Compass?
In this cohort petrols pass 82.6% of tests against 77.4% 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.
