Vehicle: 2023 Hyundai Nexo Limited VIN: [XXX] Mileage at failure: ~12,077 Location: California What is the problem? After Hyundai performed Safety Recall 269 (thermally-activated pressure relief device) on my vehicle, the vehicle developed a hydrogen leak and was declared unsafe. Hyundai advised that no repair remedy is available. When did this happen? January 13, 2026, during attempted pickup from the dealership following recall service. What happened? My vehicle was taken to an authorized Hyundai dealer for Safety Recall 269. On the evening of January 12, 2026, the service advisor called and said the vehicle was ready for pickup. When I arrived the next day, the dealer attempted to bring the vehicle out. A malfunction appeared, and after over an hour, I was told the vehicle was leaking hydrogen and was unsafe to release. The dealer retained the vehicle and provided a loaner. The following day I was informed that the vehicle would be bought back and that no repair remedy or parts are available. Why is this a safety issue? The vehicle is fueled by high-pressure hydrogen. A hydrogen leak presents an immediate risk of fire or explosion. This defect appeared only after recall service and renders the vehicle unsafe for operation or storage. What has the manufacturer done? Hyundai has not repaired the vehicle and has stated no remedy exists. Instead, Hyundai offered only to pay off the loan and provide a small cash payment, without repairing the safety defect. Has this happened before? No. The vehicle was operating normally before the recall service. What do you want NHTSA to do? I am requesting that NHTSA investigate Hyundai’s recall remedy for Safety Recall 269 on the Hyundai Nexo and determine whether the recall repair is causing or failing to prevent hydrogen leaks, and whether Hyundai is providing an adequate safety remedy. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The vehicle uses hydrogen fuel which is stored in three high pressure cylinders. Any fires or damage to the vehicle that affects the fuel system can result in an explosion. During a recent recall, customers were recommended not to park near structures because the car can explode and cause property damage. This is applicable to all hydrogen fuel cell vehicles available in the US.
