Hyundai Nexo Hydrogen Fuel Recalls and Park Outside Instructions
⚠ 3 carry a park-outside (fire risk) advisory.
These notices focus entirely on the Hyundai Nexo's hydrogen fuel system, with hydrogen leakage and fire risk recurring throughout. The April 7, 2022 recall covers certain 2019 Nexo vehicles whose inlet receptacle filter could detach following hydrogen refueling and cause a leak. The April 14, 2022 recall covers certain 2019-2021 Nexo vehicles with hydrogen detection sensors that may fail to detect leaks. The October 2024 notice describes certain 2019-2024 Nexo vehicles whose thermally activated pressure relief device may break, releasing hydrogen and potentially causing a fire while parked. The 2019 Nexo appears in each notice, and each notice directs owners to park outside away from structures until repaired.
Warning signs to watch for
- The notices for these recalls do not describe any warning sign an owner would notice.
Can you keep driving? What the notices say
All three notices carry park-outside instructions: the April 7, 2022 Nexo hydrogen inlet-receptacle recall, April 14, 2022 Nexo hydrogen leak-detection recall, and October 11, 2024 Nexo pressure-relief-device recall. Each tells owners to park outside and away from structures until the recall repair is complete. None tells owners to stop driving. The sensor notice describes fire risk while parked or driving; the pressure-relief-device notice describes a possible fire while parked. These instructions do not establish that driving an affected Nexo is safe.
What the free repair involves
Dealers replace the hydrogen fuel inlet receptacle under the April 7, 2022 recall and the hydrogen gas detection sensors under the April 14, 2022 recall. The October 2024 recall calls for replacement of the thermally activated pressure relief device, or TPRD. Each notice states that its replacement is free of charge.

Common questions
Which Nexo recalls tell owners to park outside?
The April 7, 2022 inlet-receptacle recall, April 14, 2022 hydrogen detection-sensor recall, and October 11, 2024 pressure-relief-device recall each direct owners to park outside and away from structures until the specified recall repair is completed.
Does the hydrogen sensor recall mean the sensors cause a leak?
The April 14, 2022 notice says hydrogen gas detection sensors may fail to detect leaks in the hydrogen delivery system. It identifies undetected leakage as the concern and calls for free sensor replacement on certain 2019-2021 Nexo vehicles.
What breaks in the Nexo pressure-relief-device recall?
The October 2024 notice says the thermally activated pressure relief device may break and cause a hydrogen gas leak, potentially resulting in a fire while parked. Its problem description covers certain 2019-2024 Nexo vehicles. Dealers replace the device free.
