What's wrong?
The Integrated Electronic Brake system on 2019-2021 Hyundai Kona Electric and Nexo vehicles uses electronic control software to help provide power-assisted braking. When you press the brake pedal, the system reads sensor signals and commands the brake motor so the hydraulic brakes get the assist they need. That assist helps the vehicle slow with normal pedal effort.
On affected vehicles, the brake control software responds incorrectly when it detects an abnormal sensor signal. Instead of keeping the brake motor available through a fail-safe path, the logic disables motor operation. With the motor disabled, braking assist drops and foundational brake performance is significantly reduced. The software update keeps braking performance available when a fault is detected.
There is no warning sign before failure. The filing describes warning lamps or reduced braking performance in claims reviewed during the investigation, but it does not give owners a reliable advance symptom.
Who's affected?
Kona Electric and Nexo models are grouped together because the same hydraulic brake system software is involved across 2019-2021.
