2017 Subaru Outback engine problems

Pulling into our garage (as we have done probably thousands of times since owning the car), our 2017 outback accelerated out of control into the back wall of our garage. Car had been stopped at the parking position in the garage and was being shifted into park when the acceleration occurred. Gas pedal was not touched (car always coasts into garage under it's own power, and foot is only on the brake always). Extensive damage to car and garage. Both subaru and our insurance company have been alerted.

Driving back to michigan from florida, my 2017 subaru outback (6000 miles) stalled twice unexpectedly in heavy traffic conditions on I75. The vehicle was in stop and go traffic when it stalled. I coasted to the median, placed the car in park and restarted the engine. (both times) the condition has not repeated itself since, now has (7800 miles). Subaru dealership could not replicate the problem and subaru customer service cannot resolve the issue.
