Drivers of Hyundai Nexo vehicles are experiencing unexpected and potentially dangerous symptoms as a recall unfolds addressing hydrogen system faults.
At a Glance
- Hyundai recalling 1,568 Nexo models due to hydrogen gas leak risk.
- The 2019–24 models are the focus of the recall.
- Unique hydrogen-powered vehicles face safety device issues.
- No related incidents have been reported so far.
- Repairs involve replacing a glass component with metal.
Potentially Dangerous Symptoms
Hyundai Motor North America is alerting owners of the 2019 to 2024 Nexo models about faults in their hydrogen systems. These issues manifest through a loud wind-rushing noise, mysterious white fog-like clouds at the rear, rapidly dropping fuel gauges, and malfunction indicator lights. These symptoms could signify significant safety risks, prompting Hyundai to conduct a recall.
The precise problem involves a safety device that, if the fuel tank overheats, releases hydrogen gas. The device uses a thermally-activated pressure release mechanism with a glass bulb, which may crack prematurely and lead to leaks.
“To ensure the safety of its customers, Hyundai Motor North America is conducting a safety recall to address a condition involving the thermally-activated pressure release device,” a spokesperson for Hyundai said.
The recall includes 1,568 Nexo models, which are among the first mass-market vehicles powered by hydrogen. These vehicles are still very rare, with only around 17,000 on U.S. roads by mid-2022.
Safety Measures and Resolution
Hyundai has advised owners to park their vehicles outside and away from buildings until these issues can be resolved. Dealers and owners are expected to receive notifications by December 10, ensuring that everyone affected remains informed. Customers will also be able to check their vehicle’s recall status online on Hyundai’s website.
The fault stems from a part supplied by Youngdo Industry in South Korea. To correct this fault, Hyundai will replace the problematic glass bulb with a metal version. Thus far, no incidents, crashes, or fires linked to these hydrogen system issues have been reported in the U.S. or Canada.
Although Hyundai understandably wants to ensure that the hydrogen-powered Nexo remains safe and reliable, the recall serves as a reminder of the complexities involved in adopting cutting-edge fuel technologies. As the country gradually strives towards sustainable options, it is paramount that automakers like Hyundai continue to prioritize safety and performance.
