The picture
Across 2,781 MOT tests, the Kona Premium Gdi Hev S-A returns 88.3% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a seriously damaged tyre. A defective wiper blade and a tyre with the cords showing round out the top three. Average tested mileage sits at 21,932, 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 Hyundai Kona Premium Gdi Hev S A makes little measurable difference to MOT outcomes.
Best band to buy
87.0%
2018–2020 registration
the 2018–2020 band climbs to 87.0% — a 0.4-point improvement. Failures here are mostly wear items: has a cut in excess of the…, does not clear the windscreen effectively — the structural issues that drag down older examples don't appear in the top-10 for this band.
Band to be cautious about
86.6%
2021+ registration
On the 2021-on band, the data shows a 86.6% pass rate against a fleet average of 87.0% on the newer band. The main culprits logged at test: has a cut in excess of the…, has ply or cords exposed, and blade defective. Average mileage on test for this band is 22,918 miles — high-mileage wear items are a recurring theme.
Best band to buy: 2018-2020 (87.0% first-time pass). Worst band to avoid: 2021+ (86.6% pass). That's a 0.4-point spread across 4,374 older tests and 4,250 newer ones — year of build makes a material difference on this model.

What's good
The Kona offers the choice between two turbocharged, small-displacement petrol engines. A 1.0-litre T-GDI with a 6-speed manual transmission and 120PS as standard and a high-power 1.6-litre T-GDI with 177PS with and Hyundai’s self-developed 7-speed dual-clutch transmission and four-wheel drive.
Where it falls short
For the first time in a Hyundai, the Kona's new head-up display projects relevant driving information directly into the driver’s line of sight. An optional eight-inch infotainment system integrates all navigation, media and connectivity features, supporting both Apple CarPlay and Android Auto. The system comes with a seven-year free subscription to LIVE Services, offering updated information in real time: weather, traffic, speed cameras and online searches for points of interest.
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 Kona Premium Gdi Hev 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.
