2020 Hyundai Nexo Complaints

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. There is no warning light indicating this issue when driving the Nexo u...

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 five minutes) and has not be...

I received a safety recall on this car via mail. I brought it to the dealership service center in van nuys, ca, to which they said no recall currently exists on this car. A month later, I’m now experiencing a sensor of the fuel cell system failure. In addition, the CarPlay function on my car has not been working for 2 years and both Tustin and van nuys Hyundai dealership fail to fix it

The city I live is located on top of a hill/low mountain. When I drive uphill by following speed limits to my home the car often can't keep recommended speed (45 mph). The speed drops significantly(can go even 25 mph) and unpredictable. At the beginning I believe the car was able to keep the speed but it slowly started losing the power. The risk is that a vehicle behind might not expect such behavior from my car and also changing lanes is tricky because it can't accelerate and it moves slower than other cars on the road. I've contacted dealership's service two times but they didn't find any issue. I also contacted Hyundai's customer support but they wasn't able to help me as well. The person from the service said that Hyundai is aware of the situation but they don't have any solution. My guess is that the problem is with battery. Battery performs as buffer to power electric engine in hydrogen fueled vehicles. When I drive uphill the battery probably drains fast and the energy from hy...
