Cx-30 Sport Lux Mhev Auto: a strong MOT record by UK norms
Across 533 MOT tests, the Cx-30 Sport Lux Mhev Auto returns 95.7% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is windscreen damage. A defective wiper blade and a seriously damaged tyre round out the top three. Average tested mileage sits at 18,972, 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.
