The 2010 Subaru Forester when the Subaru was in reverse while being parked it accelerated (lunged) forward at a high speed and I DID NOT put the gear shift in forward! The 2010 Subaru Forester crashed into the back of a neighbor's Honda. My personal safety was put at risk due to without me doing so, the Subaru accelerated forward causing damage to both the Subaru and my neighbor's Honda. Had this happened if someone was walking by and there was not a car to block the Subaru, they would have likely been killed. Once the Subaru stopped, the gear shift was in park and I did not move it there. Then it was very challenging to put the gear shift in reverse to back the Subaru off the Honda.
