2019 Hyundai Ioniq Hybrid

What component or system failed or malfunctioned, and is it available for inspection upon request? Braking and acceleration control, yes How was your safety or the safety of others put at risk? The car continued to move/accelerate after depressing the brake pedal, and upon applying additional force continued to move forward, this could lead to a situation where a diver is unable to stop their car when they need to. Has the problem been reproduced or confirmed by a dealer or independent service center? No Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle was inspected by a Hyundai service center on 10/09/2025 (For a similar concern and related damage) and the event occurred on 10/12/2025 Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There was no warning lights, symptoms (other than the prior occurrence of this issue). The issue was first noticed on 10/3/2025 when the vehicle accelerated while the driver was depressing the brake and damaged the undercarraige.

While attempting to park and depressing the brake the car made a sudden acceleration without input and hard braking did not slow the car. The car then impacted the curb. On another occasion while stopped at a red light the car began to move forward while the break was depressed. Pressing the break with additional force did not stop the vehicle and it continued to roll forward.

One morning, my father turned on the car. It was still in Park. He and my mom heard a noise, as if my dad was pushing on the gas pedal, but he was not. They turned off the car, turned it on again, and everything seemed fine. After driving for a bit, my father was back home and parking the car. Because of the way the parking lot is, you have to go slowly, less than 10 miles an hour, pushing on the gas a little to go up and incline and then turn right to slide into the parking spot as you break to finally park. As he was pulling into the parking spot, the car suddenly accelerated uncontrollably, and crashed hard into the building ahead. It broke pieces of the building, and the entire front of the car is totaled. My parents saw fire under the hood and my mom suffered a hand injury. They are otherwise unharmed. I know Unintended Sudden Acceleration was an issue with Ioniq EVs from 2019. It looks like it is happening to the hybrids as well. Thank you for looking into it.
