I was pulling into an open available parking space in a hospital parking garage and the car just all of a sudden accelerated ON ITS OWN and hit the wall of parking spot. I tried to apply the brake several times before I could finally get it to stop and during this time the car was slamming into the wall area and slinging me back and forth a few times before it stopped. My life was put at risk because i got hurt badly I am brusied all over my neck, chest, legs and lots of internal brusing from the hitting of the wall repeatedly. If anyone else would've been in the car they would've been hurt as well but luckily i just dropped a passenger right before the incident. The car speeding up without warning is very dangerous! There were no warnings. I just bought the car 2 weeks before this happened and now I am scared to drive this vehicle! Vehicle has been inspected unknown if anything was found yet. I need to get the black box checked out to find out what caused this to happen.
