The picture
Across 6,315 MOT tests, the Gr Yaris Circuit 4wd returns 95.0% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a tyre with the cords showing. Windscreen damage and a non-conforming number plate round out the top three. Average tested mileage sits at 14,383, 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 Toyota GR Yaris Circuit 4wd makes little measurable difference to MOT outcomes.
Best band to buy
95.1%
2018–2020 registration
the 2018–2020 band climbs to 95.1% — a 0.1-point improvement. Failures here are mostly wear items: has ply or cords exposed, has a cut in excess of the… — the structural issues that drag down older examples don't appear in the top-10 for this band.
Band to be cautious about
95.0%
2021+ registration
On the 2021-on band, the data shows a 95.0% pass rate against a fleet average of 95.1% on the newer band. The main culprits logged at test: has ply or cords exposed, damaged but not adversely affecting driver's view, and does not conform to the specified requirements. Average mileage on test for this band is 14,200 miles — high-mileage wear items are a recurring theme.
Best band to buy: 2018-2020 (95.1% first-time pass). Worst band to avoid: 2021+ (95.0% pass). That's a 0.1-point spread across 5,789 older tests and 526 newer ones — year of build makes a material difference on this model.
