“Brand new car 30 days old. Came home and parked in our flat driveway and put shifter in park. Turned engine off and opened car door to get out and car began to roll backwards toward the street. Had to jump in before I or other people got run over. Put foot on brake. Shifter clearly in park. Car engine clearly off. Take foot off brake and car continue to roll backwards. Tried to start car but car would not let me. Put emergency brake on and turned car to auxiliary power. Display shows r (reverse) even though shifter is in park. Shifter cannot be moved. Had to have tow to dealer. …”
