The picture
Across 1,817 MOT tests, the 2 Gt Sport Nav Mhev returns 91.6% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a seriously damaged tyre. Brake pads worn below 1.5 mm and windscreen damage round out the top three. Average tested mileage sits at 16,738, 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.
