2024 Hyundai Kona

My wife was driving and braked on a hill, not in park. The emergency brake auto-engaged while she was in park, then the emergency brake disengaged automatically. The care starts rolling down the hill, the regular brakes fail and do not work after pumping them multiple times. The emergency brake won't engage either. She tries reversing and that won't work. She shifted the car into drive, car keeps rolling, then she was able to engage the regular brakes and she turned into my driveaway to avoid hitting a wall or other cars. The brake system warning light turned on during this time, indicating some failure in the brake system.

While driving my 2024 Hyundai Kona on the freeway on May 22, 2026, at approximately 9:30 AM, traveling around 75 mph, my vehicle suddenly displayed a forward collision warning on the dashboard even though there was no vehicle, object, or road hazard in front of me that would justify emergency braking. Immediately after the warning appeared, the vehicle’s automatic emergency braking / forward collision avoidance system activated on its own, causing the car to brake abruptly and rapidly decelerate in active freeway traffic. This created an extremely dangerous situation because vehicles behind me were traveling at freeway speeds and could have rear-ended me, potentially causing a serious multi-vehicle collision resulting in serious injury or death. I had no warning prior to this event, no dashboard warning lights, service messages, or other symptoms indicating a problem with the system. The suspected failed component is the forward collision avoidance / automatic emergency braking system, and the vehicle is available for inspection upon request. The issue has not yet been reproduced or confirmed by a dealership or independent repair facility, and the vehicle has not yet been inspected by the manufacturer, police, insurance representatives, or others. My best assessment is that the system falsely detected a collision risk and activated emergency braking without cause, creating a severe highway safety hazard.

While at a light, the auto stop/start kicked on but when it was time to start driving again and I pressed the gas pedal, the car would not move. There was a long beep and then the check battery icon and an alert came on my dash board stating “Auto Stop is Off. Shift to P or N and start engine manually.” When I turned off the ignition and restarted the car, the alert went off but two additional icons showed up on my dash board- check engine and check oil. Then my steering wheel locked up and I could not press on the breaks or gas pedal. I could not operate my car for more than 30 minutes.

the car loss power and shut completely off and ran into the wall with my sister and my child in there on the interstate can I please get help about this matter it could've been worse where i could've lost them forever. I don't want this to happen to nobody else they cars know about these malfunctions and still but these cars on the market for accidents to happen. Please something needs to be done about this.
