I went to dealer yesterday for warped rotors on a 2007 Tundra Crewmax limited. I talked with the service rep who I asked it this common? Why yes its a big truck and when the rotors heat up they warp, kinda like my "ford ranger". I explained I don't tow anything, haul anything heavy, no heavy braking the vehicle only has 10,789 miles on it. I went wow, great product.
