My wife was pulling into a driveway slowly approximately 5 mph when she went to stop the Toyota Highlander sped up to full speed and smash the tree while my wife was depressing the brake. All airbags were deployed and it looks like they are going to total the Toyota Highlander that has all the maintenance records very lucky to not have somebody seriously injured.
I was pulling into a parking space in a parking garage. As I was pulling in, the car unintentionally had a rapid acceleration event and crashed into a cement pillar causing the car to be a total loss.
