HYUNDAI NEXO Recalls

The Hyundai NEXO has 6 recalls spanning the 2019–2024 model years, the most serious being a pressure relief device on all 2019–2024 vehicles that can break and allow hydrogen gas to leak, creating a fire risk even while the vehicle is parked. Four additional hydrogen-related recalls round out the fuel system concerns, mostly concentrated on earlier production. On 2019–2021 models, the sensors designed to detect hydrogen leaks in the delivery system can fail outright, meaning a leak could go undetected while driving or parked. Two separate recalls on 2019 models address the same detection gap from different angles: the leak detection sensors can degrade over time and stop triggering the dashboard warning light, and the hydrogen fuel safety valve can fail and leak. There is also a 2019-specific issue where the filter inside the hydrogen refueling inlet receptacle can detach after filling, creating another path for a gas leak near an ignition source. On the electrical side, 2020 models have a Remote Smart Parking Assist software defect that can allow the vehicle to continue moving when the system detects a malfunction rather than stopping, raising the risk of an unintended collision.
