Hyundai Kona II (SX2) (2023 – Présent)

Reliability score : 8.9/10

Hyundai Kona II (SX2) : The EV-First Evolution The second-generation Hyundai Kona (code SX2) represents a significant shift in Hyundai's design and engineering philosophy. Unlike its predecessor, which was an ICE (Internal Combustion Engine) platform adapted for EV use, the SX2 was designed as an EV first, with the ICE and Hybrid (HEV) powertrains adapted afterward. This approach results in a much more cohesive electric vehicle, featuring a completely flat floor, significantly increased dimensions (moving it to the upper echelon of the B-SUV segment, bordering on C-SUV), and vastly improved rear passenger space and cargo capacity. Visually distinguished by its 'Seamless Horizon' LED light bar, the Kona II offers a highly technological interior with the new ccNC (connected car Navigation Co

✅ Strengths

EV-first platform design maximizes interior space and flat floor layout.
Excellent real-world efficiency and range on the Electric versions.
Vastly improved interior quality and technology (ccNC dual screens).
Physical buttons retained for climate control and essential functions.
Switch to an 8-speed automatic for the 1.6 T-GDi (goodbye dry DCT).
V2L (Vehicle-to-Load) capability on EV models (power external devices).

⚠️ Weaknesses

EV models use a 400V architecture, meaning slower DC fast charging (10-80% in ~43 mins) compared to the 800V Ioniq 5.
ICCU (Integrated Charging Control Unit) vulnerabilities shared with other Hyundai/Kia EVs.
Ride quality can be slightly firm on models equipped with 19-inch wheels.
Significant price increase compared to the first generation.
Intrusive ADAS (Advanced Driver Assistance Systems), particularly the speed limit warning chime (requires disabling every trip).

🎯 Verdict

Final Verdict The Hyundai Kona II (SX2) is a masterclass in how to evolve a successful formula. By designing the car around the electric powertrain first, Hyundai has solved the biggest flaw of the previous generation: cramped rear seating and compromised cargo space. For EV buyers: The Kona Electric is highly recommended. While it lacks the ultra-fast 800V charging of the Ioniq 5, its 400V system is highly efficient, offering excellent real-world range. The primary reliability concern is the ICCU (Integrated Charging Control Unit) issue—a known Hyundai quirk. Ensure the vehicle has received the latest software updates or ICCU replacement under warranty. For ICE/HEV buyers: The Hybrid (1.6 HEV) remains a stellar choice for urban drivers, while the switch to an 8-speed automatic for the 1.6 T-GDi in North America/Australia makes the pure petrol version significantly more reliable than its DCT-equipped predecessor. Overall, the Kona SX2 is a mature, tech-forward, and highly practical compact SUV.
