The picture
Across 1,534 MOT tests, the Swift Sz5 Dualjet Mhev returns 92.5% 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 windscreen damage round out the top three. Average tested mileage sits at 18,966, 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
First-time MOT pass rate split by registration band. A 6.1-point gap between bands means the year you buy Suzuki Swift Sz5 Dualjet Mhev has a real effect on what turns up at the garage.
Best band to buy
92.9%
2021+ registration
the 2021-on band climbs to 92.9% — a 6.1-point improvement. Failures here are mostly wear items: does not clear the windscreen effectively, damaged but not adversely affecting driver's view — the structural issues that drag down older examples don't appear in the top-10 for this band. Post-2020 examples are early in their MOT life and generally show the cleanest records.
Band to be cautious about
86.8%
2018–2020 registration
On the 2018–2020 band, the data shows a 86.8% pass rate against a fleet average of 92.9% on the newer band. The main culprits logged at test: blade defective, does not clear the windscreen effectively, and less than 1.5 mm thick. Average mileage on test for this band is 21,337 miles — high-mileage wear items are a recurring theme.
Best band to buy: 2021+ (92.9% first-time pass). Worst band to avoid: 2018-2020 (86.8% pass). That's a 6.1-point spread across 106 older tests and 1,428 newer ones — year of build makes a material difference on this model.
