I had 2 accidents in the same week. First one was Monday 2-20-2023. Leaving work heading home, I was at a red light. The light turned green and the car in front proceeded to go. As I hit the accelerator, my car ran into the back of a car full speed. Every attempt to stop car and was unsuccessful. I called to make appt at dealership to have car inspected. Before I could get to said appt at dealership, a very similar incident happened again 2 days later as I was pulling into parking lot of work. Pulling into parking spot, my car continued to accelerate into the building. Again, attempted to stop but was unsuccessful. I suffered mild concussion from hitting head on steering wheel. Air bags DID NOT deploy. No warning from car until impact happened. Was taken to hospital via ambulance for further examination.
