But what your not seeing about that is companys like gm,ford,dodge offer a 6 or 5 year anti corrosion warrenty. Now I may be wrong and maybe you could sue if in fact your frame were to break, but they brought this undercoating recall out regardless of your mileage. Again im not sure if they did that in fear of being sued if possiable or if it was due to customer satisfaction, Now I do know that 96-00 tacomas were being bought back due to rust holes in the frames. That may be another reason they did this undercoating thing. Im sure its alot cheaper to spray a frame then buy a truck lol.
