On 10/24/22, I was stopped in traffic at the lower end of a hill. This was in Arlington, TX on Lamar St. near Collins traveling east. Although I was using my brakes as we were at a red light, the car started accelerating forward. It would not stop with further brake usage or trying to put the car into park position. I hit the car in front of me gently. Not seeing any damage, and because the other driver did not feel the impact, I did not report the incident to the insurance company. I do not know if it was a brake problem or other problem. I recently purchased the car after my Toyota Camry was totaled at the end of July 2022. However, that car had a similar problem in another accident that was reported to my Allstate agent.
