2006 Toyota Sequoia Vehicle speed control Problems

“The vehicle vsc trac system goes on for no reason when the car is in motion (roads are straight, and dry). As a result, the brakes go into a loud grind mode and do not engage, a loud blaring beeping sounds, the vehicle starts to vibrates horribly, I can not accelerate and the steering is difficult. It is not safe, as I was on a country road going 55 MPH on a straight 2 way road with traffic! It has happened twice and as far as I can see it has happened to many other 2006 sequoias owners yet only the 2003 were recalled for this issue. Unacceptable!”

“Vsc trac on/off brake indicator lights appear while driving in the 35-45mph range. If you attempt to stop the vehicle (firm or light brake pressure), there is a loud grinding noise, as if it is activating the ABS, which takes a little longer to come to a complete stop. It would've been nice if Toyota created a vsc trac on/off switch (at this rate, I may have to create my own). Some websites mention dirty sensors (speed sensors), some mention possible faulty yaw rate sensor (level warning switch, located in the center console), steering angle sensor may need adjusting. …”

“While driving at 35 MPH, the check engine light, vsc off light, and vsc trac light all came on at once, and the vehicle stopped accelerating, and I experienced a dramatic decrease in vehicle power. I drove the vehicle home noticing a drastic change in acceleration as the Sequoia would not accelerate normally; it would accelerate at a significantly reduced rate, topping out at 35mph on the flats and 16 MPH on an incline, in addition, during start up, the engine makes a high-pitch vacuum noise, which drops off and normal engine sound returns. …”

“Toyota Sequoia (ball joints recall) was driving on highway I-5 northbound just after the bridge that goes over the sacramento river I was on the bypass/cosway bridge driving in the #1 (of 2) lane going 65 MPH when suddenly my front end driver's side of my vehicle dropped completely and I was skidding on complete metal, I had no breaks and continued to skid for what seemed like forever, and steered to my to my right passing the #2 lane going up against the edge of the right side on the bridge. I was completely shocked. I couldn't open my driver's side door due the traffic right up against me. …”

“After putting gas in the vehicle, I pulled away from the gas station and when I came to a stop sign before entering the main thoroughfare the brake pedal was so hard to depress that I almost had to stand on it to get the vehicle to stop, and nearly was unable to before plowing into oncoming traffic I also noticed that the trac off , vsc trac , and brake malfunction indicator were all illuminated. It was a real panic situation because it was totally unexpected and my wife and 2 young daughters were in the vehicle with me. …”
