2016 Toyota Camry

While loading groceries in my trunk, the torsion bar sheared off and broke (the hook part). It fell hard on my shoulder (fortunately not my neck or head). I have never seen steel actually break rather than bend. I tried to fix it but could not. Trunk is heavy and unstable (falls easily), as is part of car in back. Went to Toyota dealer and found out no recall, and "iffy" fix. They wanted $488.50 to try and fix. My body shop estimated $164. and purchased correct Toyota parts, followed their instructions. The bars only held for a few minutes, then they failed to hold up the trunk again. I was almost injured again with this failure, but managed to catch it in time. They refunded me $100. since they said there was no more "play" to work with. Went on social media only to find that many Toyota Camry 2016 and 2015s had torsion bar failures, with no recall. Some said that they spent over $1000. trying to fix it, but never could, no matter what dealership or body shop repaired it. Others gave up and sold it. It is not something that I can "live with". the trunk is heavy to life and unstable. Have to hold it while trying to put things in trunk. I have had 6 Toyotas in my life and 3 cars with Auto Nation, but have never had the lack of integrity, follow-through and non-solutions that I have experienced with the purchase of this car. Unlike others, I can't afford to sell/replace my car at this time, and can't live with it as is. I truly love my car, but do not feel safe using it and am totally frustrated. All I want is for Toyota and/or its mfr.) to own up to the design flaw and either fix or replace it. Note: I have photos of broken part, failure, and estimates, but couldn't get them to download onto your form. (It just kept deleting the form and having me start over). Please advise if I can send another way.
