“While I was driving, my seat back suddenly started reclining backward. I could not make the seat stop or go forward with pushing the power seat button control. It kept reclining back, pushing into the back seat and would not stop until there was no power left. Had my child been in the seat behind me, instead of behind the passenger seat, her legs would have been crushed. I took it to a vehicle repair shop and they were able to manually put the seat back to an upright position. I have not let my child ride in the back seat after that incident yet. …”
