2014 Subaru Outback drivetrain & axles problems

Tl* the contact owns a 2014 subaru outback. After parking the vehicle and exiting, the contact re-entered the vehicle and the gear rolled out of park. The emergency brake was not engaged. As a result, the vehicle crashed into the back of the contact's house. The contact sustained bruises to the legs and knees. The contact held onto the driver's door, but was unable to apply the emergency brake as the vehicle gained speed. None of the air bags deployed. A police report was not filed. The vehicle was not repaired.

There is a hesitation when accelerating, it happens from complete stops by stepping on the gas, and while turning your vehicle. I was on a 35MPH. Back road and went to turn left onto a side street, I yielded for 2 cars and then went into the turn and stepped on the gas, it hesitated and then I was hit in the rear side of my vehicle. If it would have responded correctly I would not have gotten into the accident.
