What component of system failed or malfunctioned" Sudden deceleration, not sure what system this is a part of. Is it available for inspection upon request? No, I don't know what is causing the problem so have not been able to have the specific system looked at. How was your safety or the safety of others put at risk? I have been driving on the highway and experienced sudden deceleration of the vehicle multiple times over the past four years. Not being able to control deceleration puts me and the people around me at risk for collision. I am also at risk of being stranded far from home where assistance may not be readily available. Has the vehicle or component been inspected by the manufacturer, policy, insurance representative or others? Yes, by four separate dealerships. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear" Check engine light came on shortly after deceleration, battery power could then be seen at a critical low.

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.
