Other Fuel System Tank Mounting problems of the 2003 Toyota Tundra

Took 2003 Toyota Tundra in for frame rust corrosion program 09v-444000. Was told frame and other components had extensive rust and multiple 10mm holes by lead service technician at local Toyota dealership. Service manager explained that my 2003 Toyota Tundra frame was extensively rusted and unsafe to be on the road and they wanted to take my truck immediately and provide a rental car due to safety concerns. Asked for a plan of action of the scope of work to be performed (corrosion compound verses frame replacement) before giving possession of vehicle. Photos of 2003 Toyota Tundra frame, rear cross members, spare tire carrier, rear brake lines & fuel tank mounting system were taken and sent to lead service tech three states away in texas. Was informed extensive frame rust exists on all components (frame, rear cross members, spare tire carrier, rear brake lines & fuel tank mounting system) but it is not covered because vehicle is no longer registered in wisconsin. Purchased this 2003 Toyota certified vehicle in wisconsin in April of 2010 and no information was given to me at regarding the NHTSA investigation or any rust inspections that were performed. Toyota corporation refuses to repair, replace or add corrosion resistant compound to any severely affected rusted components. Significant rust issues exist on this vehicle and still Toyota corporation refuses to provide any documentation of their inspections. Toyota corporation will not put in writing that the frame, rear cross members, spare tire carrier, rear brake lines & fuel tank mounting system is safe or road worthy. Deadline for all rust repairs is December 31, 2012. Toyota corporation is stalling consumers to keep from doing any repairs and leaving unsafe rusted 2003 Toyota Tundra's on the highways. Please initiate a new NHTSA investigation regarding this matter for the safety of consumers.
