Transfer Case Problems of Toyota Sequoia

When I was going up a hill / dirt road in 4wheel high, at the midway point up, the engine lost power, I had the accelerator to the floor and the brake light came on and would not go off. It felt like brakes were being applied automatically. I put the gearshift in park and neutral put gear in 4 low and 4 high with and without center differential locked and unlocked with no results, vehicle would not accelerate uphill. I then had to reverse down to a level area, which was very dangerous as there was no room to turn around, after reaching a more level area, I turn off engine for about 20 minutes and when I restarted I was able to go downhill and left early from my trip as I dont want to be in this kind of dangerous situation again. Also my air conditioner is putting out strong pungent smells. I tried to clear the air by putting lever in fresh air mode as suggested by your tech, but intermittently the smell.

I am the owner of a 2002 Toyota Sequoia. Since December 2002, I have experienced a problem with the 4-wd system on the vehicle. The 4-wd problem was originally noticed by me in late November 2002. I took the Sequoia back to the dealer of purchase (burt Toyota), however the problem was incorrectly diagnosed. Subsequently, seeking a second opinion I brought the Sequoia to stevenson Toyota east. The service technician was able to verify and document the problem with the 4wd system. The service technician was unable to fix the problem and the issue was forwarded to Toyota engineering for a resolution. I was advised and shown that the problem was entered into the Toyota service computer system. I was also told that once Toyota determines a resolution I will be notified and the problem covered as a warranty issue. To date, I have had no contact from Toyota, yet the problem continues to exist. The 4wd problem consistently occurs in cold weather with temperatures below 30 degrees f. I have found during warmer temperatures, above 50 degrees f, the problem has not been noticed. During cold weather, frequently the vsc on, vsc off and brake light indicators remain lit on the dashboard while driving. Sometimes the center yellow indicator in the 4wd display also flashes yellow. The resolution to this condition most of the time, is once the car is completely warmed up to stop, shut off the ignition and restart the vehicle. Mostly, we watch it all the way on the commute home and to work as there are not many places to stop along the highway! in 2wd mode, there is a noticeable grinding /whining coming from the front transfer case. This is especially noticeable at low speeds. It sounds as if the front transfer case is partially engaged. The resolution to the noise is to place the vehicle in 4wd mode. The sound then seems to go away.
