The picture
Across 6,647 MOT tests, the Puma St-Line X Mhev returns 92.0% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is brake pads worn below 1.5 mm. A seriously damaged tyre and tyre tread under the limit round out the top three. Average tested mileage sits at 21,701, 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 Ford Puma ST Line X Mhev makes little measurable difference to MOT outcomes.
Best band to buy

2021+ registration
the 2021-on band climbs to 93.1% — a 0.9-point improvement. Failures here are mostly wear items: has a cut in excess of the…, 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
92.2%
2018–2020 registration
On the 2018–2020 band, the data shows a 92.2% pass rate against a fleet average of 93.1% on the newer band. The main culprits logged at test: has a cut in excess of the…, less than 1.5 mm thick, and tread depth below requirements of 1.6mm. Average mileage on test for this band is 28,465 miles — high-mileage wear items are a recurring theme.
