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 Nexo’s 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 defective systems that fail to perform as promised. Plaintiffs argue that these defects compromise the vehicle’s performance, including the core hydrogen fuel cell stack, leading to reduced reliability and substantial safety concerns.

PLEASE SEE ATTACH FOR DETAILS 1. Component or System Involved The Fuel Cell System and Accelerator Pedal Control System are suspected to have malfunctioned. The issue is characterized by the vehicle's failure to respond to input from the accelerator pedal, particularly at speeds between 45-65 mph, which may be linked to increased power demand from the fuel cell system. The system is available for inspection upon request, as the issue is ongoing. 2. Safety Risks The malfunction poses a serious safety risk to the driver, passengers, and other road users. Sudden and unexpected loss of acceleration while driving, overtaking, or climbing inclines creates a high risk of collisions, especially on highways where traffic moves at high speeds. Other drivers may not have sufficient time to react, leading to rear-end collisions or side-impact crashes. 3. Problem Reproduction and Confirmation The problem occurs consistently after driving for a short period (less than...
