On XXX, I was driving my 2021 Toyota Highlander at approximately 55 mph when a deer entered the roadway and I had to brake suddenly to avoid a collision. My [XXX] daughter was properly seated in the second-row seat and was properly restrained by her seatbelt. During the braking event, the second-row seat unexpectedly folded forward while she was seated in it. As a result, my daughter experienced rib pain and soreness that lasted several days. After the incident, the seat was returned to the upright position and appeared to latch normally. The vehicle is subject to a recall involving the second-row seat. I contacted Toyota Customer Care on XXX, and Toyota provided a rental vehicle on XXX, while the recall issue is being addressed. I am reporting this incident because the recalled seat failed during an emergency braking event and resulted in injury to a child passenger.
