Hyundai Tucson IV (NX4) (2020 – 2025)

Reliability score : 8.3/10

The fourth-generation Hyundai Tucson (NX4) marks a radical break from its predecessors. Introduced late 2020, it features the “Sensuous Sportiness” design with its grille integrating parametric daytime running lights invisible when stationary. Based on the N3 platform, it offers a spectacular leap forward in terms of perceived quality, spaciousness, and onboard technologies. It is available in two wheelbases: short (SWB) for Europe and the Middle East, and long (LWB) for North America, South Korea, and Australia. Mechanically, this generation emphasizes electrification with the massive introduction of the Smartstream engine family, integrating CVVD (Continuously Variable Valve Duration) technology on petrol engines. A facelift was presented late 2023 for the 2024/2025 model year, correctin

⚠️ Weaknesses

🎯 Verdict

The Hyundai Tucson IV (NX4) is an extremely accomplished compact SUV that has managed to challenge European and Japanese benchmarks. Its overall reliability is very good, supported by the maturity of the Smartstream engines. Purchase is highly recommended, particularly in the 1.6 T-GDI 150/180 hp or 2.5 GDI (depending on the market) versions. However, a strict warning is necessary for HEV and PHEV versions: although mechanically reliable, they suffer from chronic clogging of the gasoline particulate filter (GPF) if used exclusively for short, cold journeys. If you drive less than 15 km per trip daily, opt for a standard petrol version or make sure to take a long monthly highway trip to regenerate the system.
