Common 2019 Hyundai Nexo problems
The Hyundai Nexo, a hydrogen-fuel-cell-powered crossover, has been praised for its eco-friendly nature, as it emits only water vapor. However, it comes with a high starting price of $58,300 in California, making it more expensive than a base Audi Q7.
One of the significant issues with the 2019 Hyundai Nexo is the possibility of leaking hydrogen, which could lead to a fire. Hyundai has recalled 54 examples of the 2019 Nexo due to this problem. The receptacle filter can detach immediately after filling with hydrogen, causing the refueling inlet not to seal correctly. This issue can lead to fuel leakage, and in the presence of an ignition source, there might be a fire.
Another issue that Nexo owners have reported is the unavailability or malfunctioning of hydrogen fueling stations. Although the Nexo is exclusively available in California, where there are enough publicly available hydrogen refueling stations, some owners have reported that the stations are not working. The price of hydrogen has also doubled in the last year at some stations, making it even more expensive to refuel the Nexo.
The Nexo's high mileage service, which includes flushing the system, is another concern for potential buyers. At around 30-36k miles, the service costs about $1,200, which is a significant expense for Nexo owners.
Lastly, the Nexo's push-button gear selector has been criticized by some reviewers, who found it unintuitive and not user-friendly. However, the rest of the cabin is generally well-received, with a comfortable ride and quite responsive handling.
In summary, the 2019 Hyundai Nexo has several issues that potential buyers should be aware of, including the possibility of leaking hydrogen, unavailability or malfunctioning of hydrogen fueling stations, high mileage service costs, and the unintuitive push-button gear selector. However, the Nexo's eco-friendly nature and comfortable ride are also significant advantages that may outweigh these concerns for some buyers.

What is the real range of a Hyundai Nexo?
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.
Does Hyundai Nexo have a battery?
NEXO's fuel cell system combines oxygen and hydrogen to create a flow of electrons that powers the electric drive motor and charges the 1.56kWh high voltage battery.
What is the fuel cell efficiency of the Hyundai Nexo?
The maximum fuel cell efficiency is found to be 66.8% at system level and 67.5% at stack level. This maximum efficiency is located at 8–10kWe system power which roughly translates to 10% of maximum system power.

FUEL/PROPULSION SYSTEM PROBLEM
- Date Of Incident: 2022-04-29
- VIN: KM8J84A68KU
- Components: FUEL/PROPULSION SYSTEM
- Summary: I bought a 2019 Hyundai Nexo Fuel Cell on 04/29/2020 from Lithia Hyundai of Mission Hills without been notified of the two existent recalls with no remedy yet available from Hyundai. In fact, these Recalls shown in the Carfax report, were undisclosed by giving me to sign the last page "as a confirmation I was going to receive it complete". At the end of the process, I received a USB with the purchase documents and it was until two days after when I printed all documents, I found out about the recalls. Is it fraud?
UNKNOWN OR OTHER PROBLEM
- Date Of Incident: 2021-09-02
- VIN: KM8J84A6XKU
- Components: UNKNOWN OR OTHER
- Summary: Indicated that there is delay of acceleration on the high driving when I push the gas pedal, it doesn't linearly speed up instead it reduced the speed while I was pushing the gas pedal, worried about the behind car didn't notice the car is slowing due to this issue, it may incur the unexpected accident due to unexpected speed down on the highway driving. Put my car in the dealer to take a look at the issue, they indicated the issue and performed several software upgrade but they failed several times and it still didn't get fixed yet. I also heard that it has orange warning message which need to replace hydrogen related coolant must be replaced but they don't have parts to replace it immediately. There is no actual incident so far, but worrying about this unexpected delay of acceleration, and unexpected speed down could cause the accident. But they cannot figure it so far, been 4months.
SERVICE BRAKES PROBLEM
- Date Of Incident: 2019-10-08
- VIN: KM8J74A6XKU
- Components: SERVICE BRAKES
- Summary: WHEN THE CAR IS MOVING, A "REGENERATIVE BRAKE SYSTEM FAILURE" MAY OCCUR. WHEN THIS ERROR OCCURS, BRAKING EFFECTIVENESS IS DRAMATICALLY REDUCED AND THE CAR'S SPEED IS LIMITED TO 13 MPH. ADDITIONALLY, THE CAR WILL NOT CREEP FORWARD OR HOLD POSITION WHEN THE BRAKE IS RELEASED, POTENTIALLY ALLOWING THE CAR TO ROLL BACKWARD WHEN THE BRAKE IS NOT APPLIED. THE FAILURE OCCURS MOST COMMONLY WHEN THE CAR IS CREEPING FORWARD IN TRAFFIC, BUT CAN ALSO OCCUR AT FREEWAY SPEEDS. TURNING OFF THE CAR, RESTARTING IT, AND PULLING FORWARD - IN THAT ORDER - WILL CLEAR THE BRAKE FAILURE WARNING LIGHTS AND RETURN THE CAR TO NORMAL OPERATION UNTIL THE NEXT FAILURE. TIME BETWEEN FAILURES CAN BE AS LITTLE AS A FEW MINUTES AND AS GREAT AS A FEW DAYS. THE FAILURE SETS DTCS IN THE VEHICLE ECM BUT THESE CODES HAVE NOT BEEN SUFFICIENT FOR TECHNICIANS TO IDENTIFY THE FAULTY COMPONENTS. THE VEHICLE WAS RETURNED TO CUSTOMER WITHOUT THE TECHNICIANS OBSERVING THE FAILURE OR PERFORMING ANY FIX. THE CAR THEN FAILED AGAIN A FEW DAYS LATER AND HAS BEEN RETURNED TO THE DEALER FOR FURTHER ASSESSMENT.
