Swift Sz-T Dualjet Shvs: a strong MOT record by UK norms
Across 4,660 MOT tests, the Swift Sz-T Dualjet Shvs returns 91.6% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a defective wiper blade. Wipers that don't clear the screen and windscreen damage round out the top three. Average tested mileage sits at 19,664, 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.
