2019 Tesla Model 3 air bags problems

My wife was trying to park the car in our garage when the car suddenly sped up and hit our inner garage wall. It then reversed back and hit the wall a second time. Then it automatically reversed and parked on the neighbor's driveway. Both the sterling air bag and airbag near the feet deployed. The car's front was smashed. Our garage wall and door are also badly damaged.

I am female safe driver with clean driving records, my tesla was third car stopped at traffic light on dec 19th in the city street, and all of sudden, I strongly believe that it triggered unintended spontaneous acceleration that resulted in accident with two cars ahead of me, damaged all 3 vehicles including mine, I pushed the brake immediately & parked before all airbags in my car deployed.
