during a low speed parking lot stop the 2nd row bench came unlatched, the seat bottom dropped and slid forward. my [XXX] son who was in his forward facing car seat slammed into the back of the driver seat. then the bench seat was jammed in this position, he was smashed and stuck between his car seat and the driver seat, the bench seat would not move, it was stuck and my child was trapped, screaming and bleeding from his face. i had to use the driver power seat functions to move it forward to get my child un trapped. once out we tended to his medical needs as he was bleeding from his face and screaming. the seat is still stuck in this forward/dropped position and will not move. the seat latch release handle has no resistance and will not do anything. his car seat was still smashed against the driver seat and i was unable to get it out from the side, i had to lift it out through the sunroof to get it out! we took him to local urgent care, he has a laceration on his eye, bruising, swelling and is very emotionally upset as are we. i do have a dash cam and have the footage of the seat slamming forward.
