Seat belts

1 report1 crash
“The contact owns a 2018 Acura ILX. The contact's daughter was driving approximately 10 MPH and accelerating after stopping at a traffic sign when the vehicle was crashed by another vehicle. The contact's vehicle had the front bumper removed. There were no injuries and both vehicles were drivable. The contact's daughter had exited the vehicle and retrieved the front bumper. She got back into the driver's seat and attempted to strap the seat belt on, and found that the seat belt had become locked and would not deploy normally. The contact had taken the vehicle to a collision repair shop who advised that the seat belt was not available and the vehicle could not be released due to the failure of the driver's seat belt. The manufacturer had been informed of the failure. The vehicle had not been repaired. The failure mileage was approximately 25,000.”
