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.
