2021 Hyundai NEXO

Issue: Over time, the sensors to detect a hydrogen gas leak may degrade (and not work properly). If this happens, and there is a hydrogen fuel leak, the driver warning light may not turn on. Safety Risk: An undetected hydrogen fuel leak can create the risk of a fire, even while the vehicle is parked. Corrective Action: Hyundai will notify owners by mail and instruct you to take your vehicle to a dealership to replace the hydrogen gas detection sensors. Hyundai recommends that you may continue driving your vehicle, but that you should park it outside and away from structures until the recall repairs are completed.
