Is the 2017 Cx-5 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	87.1% +3.2 vs same-age

FAQs

Is a 2017 Mazda Cx-5 reliable?

2017-registered examples passed 86.3% of their MOT tests (21,422 tests, 2023–2025), +2.3 points versus all UK cars registered in the same year. At roughly 9 years old with a median 58,075 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2017 Cx-5?

The median tested example shows 58,075 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.
