The 2004 and earlier Toyota Tundra has had major corrosion issues and frame recalls. My Tundra was just inspected by the local Toyota dealer and major corrosion was noted on the vehicle frame. Toyota applied a fiberglass based rustproofing to the frame. However, they would not acknowledge any other corrosion or rot on the vehicle. My vehicles motor mounts are so corroded that I am afraid that the engine will fall out of the vehicle. Also, the mounts that hold the radiator are so corroded they are almost gone. There are numerous other areas in the engine compartment and undercarriage that are completely corroded. The vehicle is unsafe to drive and Toyota will not address it.
