Common 2021 Hyundai Nexo problems
Based on complaints from owners of the 2021 Hyundai Nexo, common problems reported include issues with the hydrogen gas detection sensors failing to detect leaks in the hydrogen gas delivery system, potential hydrogen fuel leaks due to the inlet receptacle filter detaching after refueling, and reduced braking performance due to abnormal sensor signals affecting the Integrated Electronic Brake (IEB) system.
- Hydrogen Gas Detection Sensors: Owners have reported that the hydrogen gas detection sensors in the 2019-2021 Nexo vehicles may fail to detect leaks in the hydrogen gas delivery system. This issue poses a risk of hydrogen gas leaks, increasing the potential for fires while the vehicle is parked or in operation. To address this, Hyundai has initiated a recall to replace the hydrogen gas detection sensors free of charge.
- Hydrogen Fuel Leaks: Another reported problem involves the inlet receptacle filter detaching after refueling, leading to potential hydrogen fuel leaks. This issue can result in fuel not sealing correctly, causing leaks that, in the presence of an ignition source, could lead to fires. Hyundai has issued a recall to replace the hydrogen fuel inlet receptacle to resolve this issue.
- Braking Performance: Owners have experienced reduced braking performance in the 2019-2020 Nexo Fuel Cell and 2019-2021 Kona Electric vehicles due to abnormal sensor signals affecting the Integrated Electronic Brake (IEB) system. This reduction in braking power could result in longer stopping distances, increasing the risk of accidents. Hyundai has addressed this by updating the IEB software to improve braking performance.
These reported problems highlight critical safety concerns related to the hydrogen gas detection system, fuel leaks, and braking performance in the Hyundai Nexo 2021 model. Hyundai has taken steps to address these issues through recalls and software updates to ensure the safety and reliability of the vehicles.

380 miles
In the Nexo, this returns up to 380 miles of emissions-free driving between refills. The downside is the nearly nonexistent national hydrogen refueling infrastructure, so the Nexo and its Mirai counterpart are only currently sold in California, where about 63 hydrogen fueling stations exist.

- Components: ELECTRICAL SYSTEM,ENGINE,FORWARD COLLISION AVOIDANCE
- Summary: The car does not automatically brake to avoid collision. I have tested the car by going straight into a large object either another car or person in front of my car and it will not brake. In addition the hydrogen sensor is not working properly as I have already been informed of from their recall number 225 NHTSA Recall 22V-258 which I just received a few days ago. I am dissappointed that it took 3 months for Hyundai to notify me of this very serious safety issue and I am now calling the NHTSA to see what options I have to return this vehicle as I do not feel safe driving, operating, or even parking my car at my home with a hydrogen sensor that is faulty as that is a very serious fire hazard.

Miles Rippin 2024-08-17
I bought this car in January 2020 and have driven almost 6k miles (as of August 2020). I really enjoy driving it. Although the closest station to me in Los Angeles is 4 miles away, with a range of 380 miles, it's just a matter of planning ahead. I have filled up in 5 minutes at various stations in La Canada, Hollywood, South Pasadena, and Long Beach, as well as other stations in Diamond Bar, Santa Monica, Woodland Hills, Thousand Oaks, Santa Barbara, and other parts of Southern California. The fill-up process is quick and easy. The only drawback I have seen is that there is only one hydrogen pump, so if another hydrogen car is filling up, you may have to wait a few extra minutes before your turn. However, this is not the car's fault, and hopefully, more hydrogen stations will be available soon. Just like an electric car, this car takes off quickly as you accelerate. I have left behind more expensive Land Rovers, BMW X5s, Grand Cherokees, and sedans from the get-go. My wife and kids tell me they feel like they are on a plane taking off and landing as the car makes almost airplane sounds accelerating and when shutting down. Although I am leasing this vehicle, I wish I had negotiated to buy it at a lower price. I can only hope that the Gen Nexo in 2023 is even more exciting and has an even longer range than this one, so I can negotiate to buy that one. My wife likes the AC in this car better than her 2019 car or my other car. Overall, I really enjoy this car, and due to COVID, almost every weekend, we try to go hiking in Santa Barbara, Solvang, Palm Springs, the mountains, the beach, etc. I think drivers should at least test drive it and not rule it out. Additionally, if you buy (not lease), you can get a $7500 federal tax credit, and California gives you a $4500 check refund. Just make sure you apply for the rebate within 90 days of purchase.
