Brought in car to have muffler checked out and my mechanic called me back after putting car on the lift. There were rust perforations the size of a football as well as openings along the whole frame. The mechanic told me it was unsafe to drive and that this was not normal wear for this vehicle. He was concerned that the drive train would fall through if we went over a big enough bump and cause an accident. The rust was abnormal and he said that it looked like it was rusting from the inside out of the frame. I called Toyota to file a claim and they had me bring it to the local Toyota dealer. They refused to send out a regional rep to look at it saying it was not under a recall of any kind. Now my car is unsafe and worthless. The Toyota Corp. Customer service told me to sell it for parts.... really"?? they did nothing and offered no answers. Please research this problem and get something done about it. Does someone have to die to get the attention" you buy a Toyota for its longevity and quality. I will never buy a Toyota again.

Both exhaust manifolds had to be replaced as they had developed leaks.

Bought November 4th 2000. New tires at 20000. Smelled exahust when vents are in recylce mode. Have a damaged exahust manifold at 55,000. Dealer has sated that none of these are under warranty. I have heard of other people having same problems. I buy Toyota for reliablity and service. I feel that I have not had the service nor the reliability expected. It would be a good sign of committment if totyota does honor a solution to these two problems, exahust manifold/exahust entering cabin.

After meeting with district parts and service operations manager steve carlson on 9/23/02. I''ve come to the conclusion that Toyota will not fix the problem I have with the smell coming from my 2001 Sequoia. First of all, I had to call the dealership at 10:30 in morning to make sure that the manager was going to be there. Second is that I got the run around about I should try a ''for fun and giggles'' by not running my recycling mode when driving with the A/C on. Third is that when the front windows are open I''m still getting the worst smell of exhaust coming from the rear. I understand his point about the balance of air with opening and closing of baffles in the rear and front of the vehicle. I want to make a note that the venting of this vehicle without the recycling on is the worst I''ve had in all the vehicles I''ve owned. The idea of asking me to use the front vents instead of recycling is a catch 22. Where if I keep the recycling on and smell the exhaust smell with it''s 0% emissions in my vehicle compared to opening the front vent and smelling the car in front of me with who knows what. Fourth, I have to get enough people to complain about this problem before Toyota will do anything to fix this design fault

We have a Toyota Sequoia, the problems are the 4 wheel drive is not operating all the time. It does not engage, when it does sometimes it does not stay in 4 wheel drive. One example is when my wife had six friends in the vehicle the 4 wheel drive did not stay engaged and the vehicle skid control made the engine loose power so she slid backwards down a hill. No one would ride in our 4 wheel drive again. The vehicle skid control activates at radom on dry pavement. The skid control makes the engine loose power while in traffic. There is also a hesitation in the engine when accelerating from a complete stop. Another problem is the braking system is anot adequate for the vehicle. The entire front brakes had to be replaced. The vehicle has been in for the same reairs at least five times and is still not working the way it should. We have all the documentation for service on our Sequoia. We have done internet research through the NHTSA and have found the same problem with other Toyota Sequoia's.
