2017 Subaru Outback body & structure problems

I had backed my car up to the front of the garage. I came to a complete stop. As I tried to put my car in park, my vehicle catapulted into the garage which was directly behind it. I believe my car experienced "sudden uninterrupted acceleration". My cinder block garage partially collapsed and need to be completely razed.

The contact owns a 2017 Subaru Outback. The contact stated that the battery drained without warning. Additionally, the liftgate would inadvertently open. The vehicle was taken to the local dealer where it was diagnosed and determined that a battery replacement was needed. An electronic update was completed. The battery had been replaced three times. The manufacturer was contacted but no further assistance was provided. The approximate failure mileage was 35,000.
