The right side power captain seat in the second row began to fold down without the button being pressed. It happened with and without the seatbelt plugged in. It came down while my toddler was in her rear facing car seat and began to crush the car seat and push on her feet. The chair would not stop the power seat motors even with both my wife and myself pushing back on the seat trying to free our daughter from the car seat. It continued to push down the moment there was more space to collapse. No errors or messages or engine lights of any sort were displayed anywhere. Even after removing our daughter it happened several times again.
