Hyundai Tucson Common Faults in the UK

NX4, 2020+compact crossover SUV. Updated 2026-05-04.

The NX4 Hyundai Tucson (2020+) is Ireland's top-selling new car for several years running and broadly reliable. Concerns: 1.6 T-GDI smart-stream engine had early oil-consumption claims (largely settled), PHEV battery cooling pump issues, and pre-2023 infotainment freezes. Long warranty mitigates most risk. Best-buy: 2023+. Worst: very early 2020 hybrids.
