Is the 2018 Outlander getting worse?

Pass rate of 2018-registered cars across recent test years:

Test year	Pass rate
2023	89.9% +1.8 vs same-age
2024	88.4% +2.2 vs same-age

FAQs

Is a 2018 Mitsubishi Outlander reliable?

2018-registered examples passed 88.5% of their MOT tests (32,055 tests, 2023–2025), +2.2 points versus all UK cars registered in the same year. At roughly 8 years old with a median 55,960 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2018 Outlander?

The median tested example shows 55,960 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.
