2023 Hyundai Nexo

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 Hyundai’s service network and the hydrogen fueling infrastructure promoted alongside the vehicle. As a consumer, I was attracted to the NEXO because of its innovative fuel cell technology, environmental benefits, and Hyundai’s commitment to zero-emission vehicles. However, my ownership experience has been extremely difficult and concerning due to both vehicle performance defects and the lack of support required to maintain and operate the vehicle safely. One of the most concerning issues with the vehicle is that the regenerative braking system does not appear to function properly. Regenerative braking is an important component of the NEXO’s efficiency and safety systems. When it does not operate correctly, the vehicle does not slow down in the expected way, and the energy recovery system that is supposed to recharge the vehicle’s systems during deceleration does not function as intended. This raises concerns about both vehicle performance and braking predictability. Another significant issue is that the vehicle’s speed appears to be limited and does not go beyond approximately 60 miles per hour. This limitation occurs even under normal driving conditions where higher speeds are required, such as highway travel. Being unable to exceed approximately 60 mph presents a safety

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.
