general problems of the 2012 Volvo S60

Volvo arrived at the hiking trailhead parking lot at approximately 10 miles an hour, slowed down more to select parking space then turn right into space in front of a cement outhouse. Space had a cement parking block. As the car was about to come to a complete stop in the space, it suddenly accelerated on its own as if the accelerator was press all the way overcoming the cement block and crashing into the outhouse. Both driver and passenger airbags were deployed. The driver never took the foot off the brake when the car accelerated. The automated braking system never deployed. Prior to the accident, the low battery warning light was on but the battery was checked out by a professional to be fully charged. We walk away from the accident bruised with back and chest pains from the seat belt but considered ourselves lucky. Had we not parked with a cement outhouse five feet in front of us two spaces over, we would have accelerated into an open field and into a forest of trees.
