Plain-English summary

Hyundai Motor America is recalling certain 2019-2024 Hyundai Nexo vehicles. These vehicles are equipped with a thermally activated pressure relief device (TPRD) in the hydrogen fuel storage system.

The pressure relief device may fail and break, causing a hydrogen gas leak. A hydrogen leak while the vehicle is parked can result in a fire, which increases the risk of injury.

The recall affects approximately 1,545 Nexo vehicles with model years 2019 through 2024.

Owners should park their vehicles outside and away from structures until the recall remedy is completed. Hyundai dealers will replace the pressure relief device at no cost. Interim safety notification letters were mailed on November 8, 2024, with final owner notification letters to be mailed in phases beginning January 6, 2025. Owners can contact Hyundai Customer Service at 800-633-5151 with questions.
