2015 Hyundai Sonata seat belts problems

Tl* the contact owned a 2015 hyundai sonata. While the contact's wife was driving 51 MPH, another vehicle collided head on into the contact's vehicle. The front passenger air bag failed to deploy. The rear middle seat passenger suffered severe spinal cord injuries (internal decapitation). The driver sustained injuries to the shoulder, ankle, foot wrist, hand, and hips.

Me and my wife were out driving in traffic when I had to stop abruptly. Her seatbelt did not lock in place and she injured her neck. We did not seek medical attention, due to her not wanting to. This poses a serious health and safety risk for anyone in my passenger seat. After this event, we drove to an isolated area to test if the seatbelt would lock at speeds of 30, 25, 15, and 10. The seat belt did not lock into place causing my wife body to move forward.
