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 Corolla Icon Tech Hev Cvt makes little measurable difference to MOT outcomes.
Best band to buy
89.8%
2021+ registration
the 2021-on band climbs to 89.8% — a 0.5-point improvement. Tests in this band average 40,724 miles — roughly 9K miles fewer on the clock than the older band. Failures here are mostly wear items: blade defective, 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. Post-2020 examples are early in their MOT life and generally show the cleanest records.
Band to be cautious about
89.3%
2018–2020 registration
On the 2018–2020 band, the data shows a 89.3% pass rate against a fleet average of 89.8% on the newer band. The main culprits logged at test: blade defective, does not clear the windscreen effectively, and damaged but not adversely affecting driver's view. Average mileage on test for this band is 49,584 miles — high-mileage wear items are a recurring theme.
Best band to buy: 2021+ (89.8% first-time pass). Worst band to avoid: 2018-2020 (89.3% pass). That's a 0.5-point spread across 9,528 older tests and 12,014 newer ones — year of build makes a material difference on this model.
