The picture
Across 1,829 MOT tests, the Swift Sport Boosterjet Mhev returns 91.7% 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 22,237, 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. Pass rates barely move across bands here, so the year you buy Suzuki Swift Sport Boosterjet Mhev makes little measurable difference to MOT outcomes.
Best band to buy
92.2%
2021+ registration
the 2021-on band climbs to 92.2% — a 1.0-point improvement. Tests in this band average 19,924 miles — roughly 5K miles fewer on the clock than the older band. Failures here are mostly wear items: blade defective, does not clear the windscreen effectively — 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
91.2%
2018–2020 registration
On the 2018–2020 band, the data shows a 91.2% pass rate against a fleet average of 92.2% on the newer band. The main culprits logged at test: does not clear the windscreen effectively, damaged but not adversely affecting driver's view, and tread depth below requirements of 1.6mm. Average mileage on test for this band is 25,401 miles — high-mileage wear items are a recurring theme.
Best band to buy: 2021+ (92.2% first-time pass). Worst band to avoid: 2018-2020 (91.2% pass). That's a 1.0-point spread across 771 older tests and 1,058 newer ones — year of build makes a material difference on this model.
