Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“The Auto Hold feature on my Hyundai Ioniq malfunctioned, displaying a dashboard warning: AUTO HOLD conditions not met. Press brake pedal. This message randomly appears while driving or stopping, and it deactivates the Auto Hold and Electronic Parking Brake (EPB) functions. In some cases, the car rolls after stopping because the system fails to hold the vehicle. This issue compromises vehicle safety, especially on inclines or during stop-and-go traffic. It puts me, passengers, and other drivers at risk. The problem has occurred multiple times and is unpredictable. …”

NHTSA complaint #11673623, filed 2025-07
