The picture
Sq5: a strong MOT record by UK norms
Across 573 MOT tests, the Sq5 returns 88.1% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is windscreen damage. Worn suspension bushes and brake pads worn below 1.5 mm round out the top three. Average tested mileage sits at 81,149, which is the lens to read those failure rankings through. If you own one and the next test is close, the ranked list below is a sensible pre-test checklist.

Buying or keeping a Sq5?
Use the failure ranking as a pre-test checklist or a haggling lever. Treat the headline pass rate as a fleet-wide trend, not a guarantee on any individual car.
If you own a Sq5 and your last MOT looked nothing like the ranked failures above, that's normal — individual cars vary widely. The ranking shows the patterns testers flag most often across the country.
