2023 Kia Seltos Seat Belts Problems

I was in a car crash [XXX]. My 8 year old child was buckled in the backseat on the driver's side. Her seat belt failed and let her be thrown across the car into the passenger side floorboard face down. She was unconscious and lifeless, I had to pull her from the vehicle. She was life flighted to Memorial Hermann Children's in Houston, TX. She has a concussion, fractured pelvis, had a bleeding/bruised spleen, knocked her lower teeth all loose, plus bleeding and bruised gums, sore neck from whiplash and just general body pains. The police officer came to the hospital and told me they tested all the seat belts and the two back seat belts in the Kia Seltos FAILED to engage. The pediatrician physicians said this could have killed her and I need to report this to prevent more tragedies from happening. There needs to be an immediate recall done to protect the backseat passengers in these cars. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
