I was making maintenance for my vehicle and while under the car I spotted the frame is covered by excessive rust mostly on joint areas. I have read Toyota forums today and found that the problem with the frame corrosion is not only mine. Also, I have contacted Toyota dealership today and they said they are not aware of any recalls regarding this issue. Toyota must take an action to make those Sequoias more saved to drive. At least, I am expecting them to issue a recall and cover the frame with anti-rust materials.
