Hyundai Kona I (OS) (2017 – 2023)

Reliability score : 8.2/10

The first-generation Hyundai Kona (OS) is an urban SUV (B-segment) with a bold design that marked a stylistic break for the Korean brand. Launched in late 2017, it stands out with an exceptionally wide range of powertrains, covering gasoline, diesel, hybrid (HEV), and 100% electric (EV). A facelift occurred in late 2020 (MY2021), bringing a smoothed front end, the introduction of 48V mild-hybridization on some engines, a technological update (larger screens), and the arrival of the sporty N-Line trim, followed by the radical Kona N version. Overall, the Kona OS is a reliable vehicle, supported by the 5-year unlimited mileage manufacturer's warranty, although some transmissions (DCT7) and the first generation of EV batteries experienced issues.

✅ Strengths

Original and distinctive design
Ergonomics of physical controls (climate control, shortcuts)
Excellent reliability of the Hybrid (HEV) version and the 1.0 T-GDI
5-year manufacturer's warranty (reassuring for used cars)
Rich technological equipment from intermediate trims
Remarkable efficiency of the electric version (64 kWh)

⚠️ Weaknesses

Limited trunk volume for the category (361 liters)
Average rear passenger space (legroom)
Firm suspension, especially with 18-inch wheels
Hard interior plastics and prone to scratches (pre-facelift)
Driving pleasure of the DCT7 dual-clutch gearbox at low speeds

🎯 Verdict

The first-generation Hyundai Kona is an excellent used car choice, provided you carefully select its engine. For gasoline, the 1.0 T-GDI is the most rational and reliable choice for daily use. The Hybrid (HEV) version is the most recommendable of the entire range for its reliability/consumption compromise. The 1.6 T-GDI offers good performance, but its DCT7 gearbox requires a thorough test drive before purchase. Finally, for the North American market, the 2.0 MPI should be avoided if the manufacturer's recall has not been performed.
