I experienced sudden unintended acceleration which propelled me over a curb, up an embankment, over a boulder and into a fence. I could have been killed or I could have killed others because I had no control of the car. The Hyundai corporation will not acknowledge this. The car was inspected and declared a total loss and is being moved to a location where it can be stored at no cost. There was no warning. Also this exact incident occurred with a Hyundai Kona I owned. That incident occurred on January 8, 2026.
