2019 Hyundai Nexo Service and Repair Manual

The 2019 Hyundai Nexo is a hydrogen fuel cell SUV, and servicing one safely depends on following exactly what Hyundai published for this vehicle: high-pressure hydrogen storage, the fuel cell stack and the high-voltage drive system all have to be handled to Hyundai's own specification for this year and this powertrain, not to an approximation carried over from another model year or a gasoline drivetrain.

Known issues on the 2019 Nexo. Two recalls are on federal record for this model year, and both sit in the hydrogen fuel system. The first covers the hydrogen gas detection sensors, which may fail to detect leaks in the hydrogen gas delivery system; a hydrogen gas leak can increase the risk of a fire while parked or driving. The second covers the inlet receptacle filter, which could detach following hydrogen refueling and cause a hydrogen fuel leak; a hydrogen leak in the presence of an ignition source can increase the risk of a fire. Owners have filed 3 complaints for this model year, and Hyundai has issued 38 technical service bulletins.

Whether you are chasing a hydrogen leak warning, inspecting the storage and delivery system after a refueling fault, or working through scheduled maintenance, you stay on Hyundai's own procedure for this specific 2019 Nexo.
