Hyundai is recalling a number of 2019 Nexo models in the United States due to a possible hydrogen fuel leak.

The South Korean car manufacturer began to investigate a potential issue with the Nexo when a 2019 model caught fire at a hydrogen fueling station in South Korea. An analysis of this incident revealed that material from the fuel inlet receptacle filter detached shortly after fueling was completed. This allowed hydrogen fuel to leak from the receptacle into the fuel filler compartment.

A small fire then occurred after the owner discharged static electricity when making contact with the fueling cap. Fortunately, the fire suppression system of the refueling station quickly extinguished the blaze.

Hyundai’s investigation discovered that the receptacle filter material can detach immediately after refueling and that this increases the risk of a fire. The automaker is only aware of one incident in related to the fault and concluded that a supplier had used a prototype epoxy-bonded filter in place of the original laser-welded filter.

A total of 54 Nexo models from the 2019 model year have been recalled in the United States. They were built between August 10, 2019 and December 17, 2019.

Impacted owners will be notified of the recall in early June 2022 via first-class mail. They will need to bring their vehicles to a local Hyundai dealership where the hydrogen fuel inlet receptacle will be replaced at no cost. Hyundai will also reimburse any owners that have previously paid to have the issue resolved.
