What owners wrote

Vehicle will not acknowledge that it is in park. Forces electrical to stay on, and sometimes will not engage park so vehicle can move as if I'm neutral. Has thus far happened with vehicle stopped, but you can sometimes shut off engine and exit vehicle when it is not in park and can roll against you, or on kids exiting etc. Vehicle rolled in garage and struck, and could have crushed child against door.
