My 2004 Sequoia I BOUGHT in 2014 seemed to have a solid frame that had recently been coated. In MN within a year or two that all flaked off and severe rust was setting in. It came from Texas originally so that's why it hadn't rusted already. By 2017 there were holes in the frame behind the front tires where you can Jack it up. Now the sway bar end links I keep replacing keep breaking because of excessive frame flex I suppose. The rust is spreading like cancer, and with only about 140k, the rest of the vehicle is in great mechanical condition. We are going to file with the netsa also. Obviously the 01-04 have the same problems.
