On XXX, at approximately 5pm EST, my wife stopped our 2026 Chevrolet Equinox EV after backing out of the garage and put the vehicle in park. After exiting the driver's seat, she was outside the open driver's door, had both feet on the ground and cleared the door enough that she was preparing to close it, when the vehicle began moving with no one in the driver's seat. The vehicle traveled down our inclined driveway, continued onto neighboring property, and continued through grass. A [XXX] neighboring child was in the vehicle's path. My wife believed the vehicle would strike the child and screamed for her to move. The child moved clear before the vehicle reached her, and no contact occurred. The vehicle stopped when it hit the left side of the neighbor’s garage causing damage to the stone siding and framing of the garage. The vehicle then started to move forward over the lawn and into the street. At some point after it started moving forward the neighbor, an adult male, was attempted to stop the vehicle physically but was unable to. I came out of the house and saw what was going on at this point and was able to help stop the vehicle, entered it and apply the brakes. My wife also tried to enter the vehicle and stop it during these events which ended in substantial scraps, bruising and other injuries.
