Significant Noise Problem
 I bought a new Sequoia in June 2006. The very first time I drove on interstate I noticed humming noise of drive shaft at speed of 60 mph. This is some time appreciated in old real wheel drive cars. But not in a new vehicle which costs $52000. I cannot get either dealer or Toyota to fix this or take the vehicle back. In order to stay comfortable you need to drive at the speed lower than 60 mph. I am amazed the way I am treated by Toyota and the dealership. I used to be a Toyota fan. I recommend everyone to drive this vehicle on highway before buying. I am sure some of other sequoia owners might have experienced the same problem what Toyota calls "normal characteristic of vehicle."
