I pulled my vehicle into the driveway and stopped outside of the garage. I stepped out to fold my mirrors on both sides of the vehicle as the garage is very narrow. I also need to unload my belongings from the rear hatch. I walked around to the Right side mirror, folded it and headed to unload the hatch when the vehicle PULLED ITSELF INTO THE GARAGE; literally! I could not open the doors as they lock and the space is so narrow. The vehicle stopped when it hit the back wall of the garage. I immediately opened the door and turned the vehicle off. The Vehicle sounds an alarm and shows the message "Shift to park" if not in Park. This did not happen. I sat in the car putting my sunglasses away and unplugging my phone before exiting. If I had not put the vehicle in Park, I would have heard and seen the warnings immediately and the car would have moved immediately; not 30-60 seconds after exiting. Note: our driveway is flat

This vehicle will let you shut the engine off in drive without shifting to park. If you do this and leave the vehicle on a slight incline, it will roll away and you may not be able to get back to it and into it in time to get your foot on the brake and then shift it into park. This should not be allowed. You should have to shift to park before the engine can be turned off.
