Purchased a used 2004 short bed 4×4 Tacoma. Everything looked great up on top and the underneath was coated. Have driven it now for a couple of years and love the truck. However, the whole frame underneath seems to be rusting out from underneath. I called Toyota and took it to several mechanics. Toyota says that it should have been looked at before 2011 so I am out of luck.in the mean time the frame is rusting so bad it is about worthless and Toyota says nothing can be done. I would think there should be a safety recall on these trucks to replace these faulty frames even if they weren't taken in by the previous owners?
