Trunk Lid problems of the 2016 Toyota Camry

The metal trunk torsion bar broke with no warning or symptoms while I was sitting in my vehicle with the trunk closed. While it sounds minimal, it caused such a deafening sound I initially thought there had been an explosion in the rear of my vehicle. This occurred a few minutes after I removed an item from the trunk and closed the trunk. I was sitting in the driver's seat with the car running about to back up when the explosive sound occurred. If the trunk had still been open, the risk of significant injury and death would have been quite high given the explosive sound made when it broke and slammed the interior of the trunk. If it had hit my head, chest or an artery with that level of force, it likely would have caused death in my opinion. There were zero warnings. My trunk worked fine, no symptoms of any kind that it was about to fail and that is what makes this so dangerous. This is a part that never should have failed. It should last the lifetime of the car. The largest part of the broken torsion bar is available for inspection. The smaller piece that broke off and became a potentially lethal projectile must be somewhere behind the paneling, but I have not been able to find it. I can make my car available if an inspector would like to search for the missing piece. I have received a quote from the dealer for replacement, so it has been inspected. Components that failed in the trunk: 64531-06500 hinge torsion bar right hand 64127-06110 torsion bar bracket/hardware kit. Rear spoiler/hardware kit note- there is also a 64532-06500 hinge torsion bar left hand that could possibly fail in the same way.
