Is the 2018 Q5 getting worse?

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

Test year	Pass rate
2023	90.5% +2.4 vs same-age
2024	89.3% +3.1 vs same-age
2025	88.5% +3.8 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 Audi Q5 reliable?

2018-registered examples passed 89.5% of their MOT tests (38,931 tests, 2023–2025), +3.1 points versus all UK cars registered in the same year. At roughly 8 years old with a median 50,212 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2018 Q5?

The median tested example shows 50,212 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.
