I pulled into the garage and pushed the button to turn the engine off. The vehicle was still in drive. All doors locked when they were closed. I could not open the door with the button on the door handle even though the fob was on me. I went to the back to open the rear hatch. I could not. The vehicle stated to roll backwards - there is no incline in the garage - it is flat. I used the fob to unlock the door and I was able to get into the car and put it in park. I have video from my outdoor camera.
