The picture
Across 1,592 MOT tests, the Vitara Sz-T Boosterjet Mhev returns 92.7% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a defective wiper blade. Tyre tread under the limit and windscreen damage round out the top three. Average tested mileage sits at 22,478, 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 Vitara SZ T Boosterjet Mhev makes little measurable difference to MOT outcomes.
Best band to buy
92.5%
2021+ registration
the 2021-on band climbs to 92.5% — a 0.4-point improvement. Tests in this band average 23,680 miles — roughly 6K miles fewer on the clock than the older band. Failures here are mostly wear items: blade defective, tread depth below requirements of 1.6mm — 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
92.1%
2018–2020 registration
On the 2018–2020 band, the data shows a 92.1% pass rate against a fleet average of 92.5% on the newer band. The main culprits logged at test: tread depth below requirements of 1.6mm, damaged but not adversely affecting driver's view, and does not clear the windscreen effectively. Average mileage on test for this band is 29,903 miles — high-mileage wear items are a recurring theme.
Best band to buy: 2021+ (92.5% first-time pass). Worst band to avoid: 2018-2020 (92.1% pass). That's a 0.4-point spread across 2,248 older tests and 3,434 newer ones — year of build makes a material difference on this model.
