This problem sometimes results in the vehicle rolling after stopping, creating safety concerns.
Common Issues
- Auto Hold malfunction. A warning message "AUTO HOLD conditions not met. Press brake pedal" appears randomly while driving or stopping and deactivates Auto Hold and Electronic Parking Brake (EPB).
- Vehicle rolling after stop. The system fails to hold the vehicle in place causing it to roll, especially dangerous on inclines or in stop-and-go traffic.
- Safety risk. The failure compromises safety and increases risk to the driver, passengers, and other road users.
- Unpredictable occurrence. The issue happens multiple times randomly without prior warning lights except the Auto Hold message.
- Brake switch or sensor defect. Linked to a faulty brake switch or sensor as referenced in Hyundai technical service bulletin TSB 23-BR-001H.
- Multiple owner reports. Many other Hyundai Ioniq owners describe the same symptoms in various online discussions.
- Lack of dealership action. Dealers have not inspected or addressed the problem despite matching symptoms and reports.
- Cruise control deactivation. Auto Hold/EPB lights activating while driving also disable cruise control unexpectedly.
- Ongoing unresolved problem. Complaints highlight the issue has persisted since purchase with no recall or effective dealer response.
- Used vehicle affected. Complaints come from vehicles purchased used with mileage increases noted prior to symptom appearance.

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. It appears to be linked to a faulty brake switch or sensor, as noted in Hyundai’s TSB 23-BR-001H. I discovered this issue is affecting many other Hyundai Ioniq owners, as seen in this discussion: [XXX] The dealer has not yet inspected the vehicle, but the symptoms match the TSB. No accident has occurred, but the safety risk is serious due to brake failure behavior. There were no visible warning lights before the issue started, just the "Auto Hold" message when the failure happens. I bought the car from a used car dealer when it had 39,000 miles. Now it has around 74,000 miles. I’m not sure if it’s still under warranty. I haven’t taken it to the dealer yet, but the symptoms match exactly what other people are reporting online.
