Slowing down to pull into a parking space when I put my foot on the brake to shift into park, the car lurched forward and accelerated over a parking barrier and into a brick wall. Unexplained acceleration. This was not driver error. I felt a few unexplained accelerations previously but thought it was a mistake on my end. In this instance, my foot was nowhere near the acceleration pedal. It was very very frightening. I am now waiting for the insurance adjusters. My car was damaged. I damaged the building and another car tat was parked inside the building. This is a significant safety issue. Consumer stated insurance provider stated it is a total loss and wants to take possession of the car.
