The picture
Across 2,208 MOT tests, the I20 Premium Mhev T-Gdi returns 87.2% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is wipers that don't clear the screen. A defective wiper blade and a seriously damaged tyre round out the top three. Average tested mileage sits at 20,968, 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.

Year-band analysis

87.3%
2021+ registration
