Kia Niro II (SG2) (2022 – Présent)

Reliability score : 8.8/10

The second-generation Kia Niro (codename SG2), launched in 2022, marks a major stylistic departure from its predecessor. Based on the K3 platform (an evolution of the previous one), it retains its multi-energy philosophy by offering three versions: hybrid (HEV), plug-in hybrid (PHEV), and 100% electric (EV). The design is distinguished by its contrasting C-pillar (Aero C-Pillar) intended to improve aerodynamics. Inside, it draws heavily from the EV6 with a dual digital display and recycled materials. The electric version (Niro EV), which replaces the e-Niro designation, retains a 400V architecture (unlike the EV6's 800V) and a usable 64.8 kWh battery. It is a rational, extremely efficient model that excels in its spaciousness and 7-year warranty, although its fast-charging power lags behin

✅ Strengths

Remarkable energy efficiency (especially in EV and HEV)
Increased rear passenger space and boot volume (475 L for the EV)
Interior ergonomics (very practical dual-function haptic shortcut bar)
7-year or 150,000 km manufacturer's warranty
V2L (Vehicle-to-Load) functionality on the electric version
Very reassuring overall powertrain reliability

⚠️ Weaknesses

Disappointing fast charging speed (DC) on the EV (peak at ~85 kW, 10-80% in 43 min)
Uneven interior materials (hard plastics omnipresent in the lower part and on door panels)
Lack of standard heat pump on the EV (often optional depending on trim levels/markets)
The PHEV's combustion engine turns on for heating (insufficient PTC heater)
Significantly higher prices compared to the first generation

🎯 Verdict

The second-generation Kia Niro is a pragmatic and extremely rational choice. In its electric version (Niro EV), it excels with controlled consumption that largely compensates for its small battery, offering a very reassuring real-world range (often more than 380 km on the highway and 450 km in mixed driving). Its main drawback remains its fast-charging power, which is outdated (85 kW max), penalizing it against a Renault Mégane E-Tech or a Tesla Model Y on very long journeys. However, its reliability is exemplary, inheriting the excellent reputation of the first-generation e-Niro. The HEV and PHEV versions are also excellent choices for those not ready for all-electric, with a special mention for the HEV, which is ultra-frugal and has no charging constraints.

Common issues

Défaillance de l'unité de contrôle de charge intégrée (ICCU) High

🔧 Dès les premiers kilomètres (problème de conception/fabrication)

💶 Généralement couvert par rappel constructeur/garantie. Hors garantie : 2 000 – 4 000 €

Vérifier si le rappel (NHTSA 23V-751 ou équivalent) a été effectué.

Problèmes de batterie 12V (décharge rapide, impossibilité de démarrer) Medium

🔧 Variable, souvent dans les 20 000 – 60 000 km

💶 150 – 300 €

Surveiller les signes de faiblesse, envisager un chargeur d'appoint si stationnement prolongé.

Bugs logiciels et dysfonctionnements du système d'infodivertissement Low

🔧 Dès les premiers kilomètres

💶 Généralement résolu par mises à jour logicielles (souvent gratuites)

S'assurer que le véhicule a les dernières mises à jour logicielles.
