Region Letter: ? Toyota has received reports that certain 2005 through 2008 model year Tacoma vehicles operated in specific cold climate areas (Cold Climate States) with high road salt usage may exhibit more-than-normal corrosion to the vehicle?s frame.
? Toyota investigated these reports and determined that the frames in some vehicles may not have corrosion-resistant protection sufficient for use in these areas.
? This combined with prolonged exposure to road salts and other environmental factors, may contribute to the development of more-than-normal rust in the frame of some vehicles.
? This condition is unrelated to and separate from normal surface rust which is commonly found on metallic surfaces after some years of usage and/or exposure to the environment.
