Is the 2015 GLE getting worse?

Pass rate of 2015-registered cars across recent test years:

Test year	Pass rate
2023	89.7% +9.2 vs same-age
2024	88.9% +10.4 vs same-age
2025	90.6% +13.5 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 2015 Mercedes-Benz GLE reliable?

2015-registered examples passed 89.7% of their MOT tests (3,782 tests, 2023–2025), +11.0 points versus all UK cars registered in the same year. At roughly 11 years old with a median 74,962 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2015 GLE?

The median tested example shows 74,962 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.
