According to the official NHTSA campaign (#20V748000), 8,176 cars are potentially affected by the "Integrated Electronic Brake System Malfunction" (although only 1% are expected to have a defect):
- Hyundai Kona Electric: about 7,704 vehicles produced from August 27, 2018 through November 5, 2020
- 2019-2020 Hyundai NEXO: about 472 vehicles produced from August 8, 2018 through April 1, 2020
Hyundai explains that "the Integrated Electronic Brake (IEB) system may detect an abnormal
sensor signal and as a result, may significantly reduce braking performance." Reduced braking power could lengthen the distance required to stop the vehicle, increasing the risk of a crash.
Fortunately, the remedy is simple - IEB software update. Because both models lack over-the-air software updates, it has to be done at a service center.
The recall is expected to begin in January 22, 2021.
