Car Accelerates On Its Own problems of the 2016 Subaru Outback

Upon slowing down & pulling into a parking space, to park my car in front of a business, my vehicle spontaneously accelerated forward, up over the sidewalk. The vehicle accelerated a 2nd time as I tried to stop the vehicle with the brakes. The vehicle did not stop until it impacted the wall of the building.

Sudden acceleration: this serious unsafe condition relates to my 2016 Outback limited 2. 5l purchased on 2/29/2016 in tampa florida. The exact same unsafe condition has happened twice; first in October 2016 at approximately 8800 miles, and second in December 2017 at approximately 24,000 miles. Description of incident: while slowly pulling into a parking space and gently applying the brake, the car's engine rpm accelerated and I had to break hard in order to stop the car. I moved the transmission to park, but the engine continued at high rpm so I moved the transmission to reverse, then to neutral, then I turned off the car off since the engine was still at a high rpm. A notice appeared in my odometer area to put the car in park, which I did. I then restarted it and everything was back to normal again. Note: I did not simultaneously push the break and the accelerator together which could possibly cause this situation. I am fortunate nothing was in front of me either time. I hope no one has been injured, but it is likely property damage has resulted. Please determine the cause and correct this potentially deadly situation. I am taking my car for a 24,000 mile service on 1/3/2017 and will document this with the dealer (mastro Subaru) at that time. I suspect this is a computer glitch, and a potentially dangerous one at that. I also suspect other car manufacturers can have this same issue if these computers and programming all come from the same third party.
