The 2020 Hyundai Nexo has 4 recalls, the most serious involving two separate hydrogen fire risks: a pressure relief device on the fuel tank that can crack and leak hydrogen gas, and sensors that may fail to detect hydrogen leaks in the delivery system, either of which can lead to a fire while parked or driving.
On the braking side, the integrated electronic brake system can misread a sensor signal and sharply reduce braking force, meaning the vehicle takes significantly longer to stop than expected. There is also a software issue with the Remote Smart Parking Assist feature, where a malfunction in the system may not halt the vehicle's movement as intended during an automated parking maneuver, raising the risk of a low-speed collision.
