On XXX, the passenger-side power sliding door of my 2024 Kia Carnival EX closed on my [XXX] child’s torso/chest while she was exiting the vehicle and did not stop or reverse before trapping her. I had walked toward the house and reached the garage when I heard an extremely loud scream of pain. I immediately ran back to the vehicle. When I reached her, I personally observed that her torso/stomach was still pinned against the vehicle by the closed power sliding door. She could not move herself away. I had to press the power door button to open the door and release her. She immediately had pain and visible linear red pressure/abrasion marks on her chest/rib area, followed by bruising. She reported increased pain with certain arm/upper-body movements and discomfort in the injured area with a deep breath. Photographs were taken immediately afterward. This occurred during normal use while she was exiting. She was not intentionally obstructing or testing the door. I had previous concerns about these doors and routinely warned my children not to activate them until everyone was clear. Approximately two weeks earlier, a separate accidental obstruction occurred with the OPPOSITE (driver-side) power sliding door. A book accidentally fell into that door’s path without the adult closing the door realizing it. When we later reopened the door, we discovered the book crushed/trapped inside the fully closed door. This was not an intentional test. There were no warning lights or messages.
