2004 Ford F-150 seat belts problems

The vehicle rolled and killed the occupant because the roof caved in. The shoulder portion of the seat belt did not hold the occupant (only the lap portion) and the occupant was partially ejected out of the rear of the cab. The vehicle was inspected and purchased by State Farm insurance since the vehicle was totaled. The 2000's Ford F-150s have roofs that are too weak to support the weight of the vehicle, thereby putting the occupants in danger of injury or death. This is well documented. There were no warnings.

This is regarding our rear seatbelts failing on our 2004 ford f-150 1. My wife putting our car seats back in the truck 2. Two seatbelts fell apart, it appears as though a nut holding them came loose 3. Ford will not fix this under any warranty since I'm outside my warranty time. In my mind this should be a recall or a lifetime warranty. Both of these seatbelts were connected to 2 of our baby seats; at any time we could have simply hit the brakes and they both would have come loose.
