2015 Ford F-150 seat belts problems

Tl* the contact owns a 2015 ford f-150. While accelerating from a stop sign, the contact crashed into the rear driver's side of another vehicle. The air bags failed to deploy and the driver's seat belt exploded, which included smoke and a burning odor. The contact sustained back injuries that did not require medical attention. The other driver was not injured. A police report was filed. The vehicle was towed to an independent mechanic and the body damage was repaired, but the failures were not diagnosed.

While sitting in my driveway getting ready to go to town, I pulled the seat belt to lock it into place when I hear a pop then the seat belt would not retract at all. It was as if the retractable spring broke. I left the truck sitting until I could get a replacement belt from Ford (450.00) to repair this safety issue. Had this belt failed in a collision it would have caused severe damage to the driver. This issue needs to be addressed before someone dies in an accident.
