What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The vehicle has become unsafe and practically unusable due to multiple technical problems, lack of service support, and the widespread unavailability of hydrogen fueling infrastructure in the Bay Area of California.
The vehicle has a material operability limitation related to its fuel/propulsion system that was not disclosed at the time of sale. After purchase, the vehicle’s real-world operation is materially restricted due to fuel availability and system limitations that prevent reliable use as represented.
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.
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.
Hyundai sells Nexo Hydrogen Fuel Cell vehicles with known Fuel Cell stack issues, leading to severe safety issues from sudden power loss when driving, especially when overtaking and driving on highways and/or uphill.
The contact received notification of NHTSA Campaign Number: 24V761000000 (Fuel system, Other, Fuel/Propulsion System); however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair.
