On 5/14/2025 at aprox 5:35pm I was completely stopped in traffic when all of a sudden my car started to accelerate without me pressing on the accelerator. I pressed the brake pedal, however the car continued to move forward, by this time the brake pedal was pressed to the floor and the car was continuing to more forward. I was stopped aprox 6 feet behind a semi truck, and ended up crashing into the back of the semi. The car continued to surge forward, even though my car was pressed against the back of the semi. It was at that time when I put the car in Neutral. When traffic started to move, I followed the truck, but apparently he did not realize I had hit him. I was able to drive home. There was significant damage to the front of my car. Normally I would get an alert if I am too close to the car in front of me to prevent an accident, the alert never came on. The airbags did not deploy. I was in 1 pedal driving mode when this happened, and after the incident I switched to 2 pedal driving. I have an app for my car and it does not state any accidents occurred, there are no alerts listed for this day.
