Kona N Line T-Gdi Mhev: a strong MOT record by UK norms
Across 1,285 MOT tests, the Kona N Line T-Gdi Mhev returns 92.1% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is tyre tread under the limit. A defective wiper blade and wipers that don't clear the screen round out the top three. Average tested mileage sits at 23,638, 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.

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.
Buying or keeping a Kona N Line T Gdi Mhev?

If you own a Kona N Line T Gdi Mhev 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.
