The picture
Cx-5 Sport Auto: a strong MOT record by UK norms
Across 649 MOT tests, the Cx-5 Sport Auto returns 91.1% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a seriously damaged tyre. A defective wiper blade and brake pads worn below 1.5 mm round out the top three. Average tested mileage sits at 22,109, 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.
