car accelerated on it's own as i was gliding into park

As I was slowly rolling into a front parking spot the car accelerated on it's own - I turned the wheel to the left so I wouldn't crash full on into the building - trying to control the car I went over a curb that was jetting out - defining the parking spaces - my right front and back tires went over the curb - just missing a tree - finally coming to a stop - if there was anyone there - I would have hit them - that day I took car to Subaru dealer/shop and told them what happened - on my paperwork "Customer states Subaru seems to excellerate (accelerate - they spelled it wrong) on its own - tech found no codes. Tech drove vehicle and could not duplicated

They also put the wrong millage on my papers work - car has 2850 - they put 5474 ! ! !

Just purchase this car July 2016 - At what point do they admit there is a problem and recall??

Does someone have to get hurt or worse??
