I am submitting this complaint to report serious safety, usability, and infrastructure-related issues concerning my Hyundai NEXO hydrogen fuel cell vehicle. 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. These issues collectively present safety concerns not only for me as the driver but potentially for other Hyundai NEXO owners who may be experiencing similar problems. I purchased the Hyundai NEXO with the expectation that it would provide reliable transportation supported by Hyundaiâs service network and the hydrogen fuel…
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 vehicleâs real-world operation is materially restricted due to fuel availability and system limitations that prevent reliable use as represented. The limitation affects the ability to operate the vehicle predictably and as intended. This issue is not cosmetic or preference-based. It affects normal vehicle operation and reliability. The condition is ongoing and reproducible. The dealer and manufacturer have been contacted. The condition has not been corrected.
Vehicle: 2023 Hyundai Nexo Limited VIN: [XXX] Mileage at failure: ~12,077 Location: California What is the problem?

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.
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 power loss issue was diagnosed to originate from a fuel-cell stack failure, one of the Nexoâs main power-train components. This is a known power-train issue to Hyundai, debated online since 2021 by consumers experiencing the same power loss, across various Hyundai web-logs. Other affected consumers filed a class action lawsuit this year against Hyundai Motor America Inc, for the same and other reasons. The lawsuit accuses Hyundai of selling Nexo vehicles equipped with defe…

Thermally Activated Pressure Relief Device (TPRD) - Fire Concern
A THERMALLY-ACTIVATED PRESSURE RELIEF DEVICE (TPRD) THAT VENTS HYDROGEN GAS TO THE ATMOSPHERE TO PREVENT OVER-PRESSURIZATION OF THE HYDROGEN FUEL TANK IN THE EVENT OF OVERHEATING IN THE LOCAL AREA AROUND THE HYDROGEN FUEL TANKS. THE TPRD IS DESIGNED TO VENTTHROUGH A GLASS BULB-TYPE RELEASE MECHANISM THAT FRACTURES WHEN A SPECIFICOPERTAING TEMPERATURE IS REACHED. THE GLASS BULB-TYPE MECHANISM IN THE SUBJECT VEHICLES COULD PREMATURELY FRACTURE DUE TO MICROCRACKS IN THE GLASS, WHICH COULD LEAD TO INADVERTENT DISCHARGE OF HYDROGEN GAS DURING NORMAL VEHICLE OPERATION. HYDROGEN GAS LEAKING IN CONFINED AREAS WITH THE PRESENCE OF AN IGNITION SURCE MAY INCREASE THE RISK OF A VEHICLE FIRE WHIEL PARKED…

This bulletin is a reminder to exercise caution when painting the Nexo, Fuel Cell Electric Vehicle (FCEV). During the painting processes, Volatile Organic Compounds (VOCs) may enter the fuel cell through openings or micro gaps in the intake or exhaust piping for the fuel cell. VOCs may damage certain components in the fuel cell causing reduced fuel-cell performance. VOC chemicals can harm the fuel cell system's performance. Precaution must be taken to seal openings for the fuel cell system before painting or placing Nexo in a curing oven.
This bulletin provides a procedure to maintain the transmission in NEUTRAL such as pushing the vehicle without starting the fuel stack or when repairs require the transmission to be continuously maintained in NEUTRAL.

In complaints filed with NHTSA for model years 2019–2026, owners most often name: fuel/propulsion system, engine, unknown or other. 22 complaints are on record.
No. A complaint is an unverified report from an owner. A technical service bulletin (TSB) is the manufacturer telling dealers how to fix a known issue; it is not a safety recall and is usually covered only under warranty. A recall is a formal safety action, and its repair is free.
File a vehicle safety complaint at NHTSA.gov. NHTSA reads every report, and patterns of complaints are what open defect investigations and, eventually, recalls.
