NHTSA Complaint #11486431 — 2003 TOYOTA TUNDRA

I just bought a 2003 toyota tundra 4wd v8 in Feb 2022 totally unaware of any recalls or frame rust or anything even closely related! After 6 months of owing this vehicle I had the wheel bearings replaced n mechanic told me my frame has so much damage due to rust n corrosion that it is eating through parts of my frame, he mentioned that toyota did recalls etc on this n I immediately called Toyota and told them along with doing research on this matter, I was told everything expired etc n nothing can be done! Well previous owner had took it in 2012 to have rust proofing done underneath n entire frame, that was just 10 years ago! Well toyota ways recall was done, apparently the remedy didnt work or my frame wouldn't look this bad 10 years later !so I believe that is a defective remedy and since I bought the vehicle knowing nothing, and do to the safety issues related too this as serious injury and or death can occur, I believe that they should replace my frame as they admitted to using inferior metal to build these and therefore leading too all these issues! Using inferior metal should make the part (frame) a defective part as well! Bottom line is iam driving a vehicle that can cause me n my family along with everyone on the road serious injury or death! They tried to fix the problem with rust proofing n by doing that in 2012 there is no way my frame should be in this.condition , therefore I should be entitled to a new remedy related to recall since the remedy the used was insufficient n defective regardless I'd it expired or anything! I also have alot of pictures of frame n the amount of rust n corrosion! Can you please let know a way too send these pictures to you from my phone! Thank you
