Year-band analysis
First-time MOT pass rate split by registration band. Pass rates barely move across bands here, so the year you buy Kia Sportage 3 Crdi Isg Mhev S A makes little measurable difference to MOT outcomes.
Best band to buy
87.7%
2018–2020 registration
the 2018–2020 band climbs to 87.7% — a 0.9-point improvement. Failures here are mostly wear items: efficiency less than 50% of the required value, 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.
Band to be cautious about
86.8%
2021+ registration
On the 2021-on band, the data shows a 86.8% pass rate against a fleet average of 87.7% on the newer band. The main culprits logged at test: tread depth below requirements of 1.6mm, does not clear the windscreen effectively, and blade defective. Average mileage on test for this band is 30,151 miles — high-mileage wear items are a recurring theme.
Best band to buy: 2018-2020 (87.7% first-time pass). Worst band to avoid: 2021+ (86.8% pass). That's a 0.9-point spread across 943 older tests and 586 newer ones — year of build makes a material difference on this model.

Where it falls short
Looks are potentially divisive. Hybrid system’s noisy when pushed. Driving experience lacks sparkle.
Use the failure ranking as a pre-test checklist or a haggling lever. Treat the headline pass rate as a fleet-wide trend, not a guarantee on any individual car.
If you own a Sportage 3 Crdi Isg Mhev S A and your last MOT looked nothing like the ranked failures above, that's normal — individual cars vary widely. The ranking shows the patterns testers flag most often across the country.
