This took place on private property in the parking lot of a commercial building. The vehicle was in motion going forward. It was decelerating head-in into a parking spot. The braking action was engaged. The vehicle had slowed to about 5 mph. My right foot was on the brake pedal and the braking was engaged. I then heard the sound of the engine revving at a very high rate. There was a high whining sound. I lost braking as my right foot depressed the pedal all the way to the floor. The car suddenly accelerated forward at an increased speed. It jumped the sidewalk curb, crossed the concrete sidewalk, and slammed into a cinder block wall column on the side of a building. The vehicle felt like it experienced sudden unintended acceleration.
