The picture
Across 983 MOT tests, the 2 Sport Nav Mhev returns 92.3% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a defective wiper blade. A seriously damaged tyre and brake pads worn below 1.5 mm round out the top three. Average tested mileage sits at 18,047, 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.
