Warranty Policy Bulletin (POL08-04): Toyota received isolated reports regarding a small number of 2001 through 2004 model year Tacoma vehicles operated in severe cold climate areas with high road salt use. They were reported to be exhibiting excessive rust causing perforation of the frame. Toyota investigated these reports and determined that the frames for this small number of vehicles may not have adequate corrosion-resistant protection for use in this environment. This combined with prolonged exposure to road salts and other environmental factors may contribute to the development of excessive rust in the frames of some vehicles.
