Customer FAQ:
Q1: What is the issue?
A1: Immediately following hydrogen refueling, the receptacle filter material could detach, impacting the sealing performance of the hydrogen refueling inlet receptacle and increasing the risk of a hydrogen fuel leak.
Q2: What is the safety concern?
A2: Hydrogen fuel leakage in the presence of a potential ignition source increases the risk of a fire.
Q3: What are the affected vehicles?
A3: Certain2019 model year Nexo vehicles produced by HMC from 08/10/2018 through 12/17/2018 for sale in the U.S.

Chronology :
March 2022
On March 16, 2022, HMC notified HMA’s NASO of an incident involving a 2019MY Nexo vehicle that caught fire after refueling at a hydrogen fueling station in South Korea. According to HMC’s analysis of the incident, material from the fuel inlet receptacle filter detached shortly after fueling was completed allowing hydrogen fuel to leak from the receptacle into the fuel filler compartment. The operator allegedly heard an abnormal noise from the rear of vehicle and opened the fuel filler door to investigate. Hyundai believes the vehicle operator’s hand discharged static electricity when making contact with the fueling cap, igniting the leaked hydrogen fuel and causing a fuel filler compartment fire. The fuel filler compartment fire was extinguished within seconds of detection by the refueling station fire suppression system.
On March 21, 2022, HMC informed NASO that the supplier of the fuel inlet receptacle used a prototype epoxybonded filter in place of the design-specific laser-welded filter. Based on this information, on March 31, 2022, NASO convened its North America Safety Decision Authority and decided to conduct a new recall of affected Hyundai Nexo vehicles in the U.S. to address the defect condition involving the hydrogen fuel inlet receptacle filter.
As of the date of this filing, Hyundai is only aware of the one (1) incident in South Korea that resulted in a fire.

According to HMC’s analysis of the incident, material from the fuel inlet receptacle filter detached shortly after fueling was completed allowing hydrogen fuel to leak from the receptacle into the fuel filler compartment. The operator allegedly heard an abnormal noise from the rear of vehicle and opened the fuel filler door to investigate. Hyundai believes the vehicle operator’s hand discharged static electricity when making contact with the fueling cap, igniting the leaked hydrogen fuel and causing a fuel filler compartment fire. The fuel filler compartment fire was extinguished within seconds of detection by the refueling station fire suppression system. On March 21, 2022, HMC informed NASO that the supplier of the fuel inlet receptacle used a prototype epoxybonded filter in place of the design-specific laser-welded filter. Based on this information, on March 31, 2022, NASO convened its North America Safety Decision Authority and decided to conduct a new recall of affected Hyundai Nexo vehicles in the U.S. to address the defect condition involving the hydrogen fuel inlet receptacle filter.
