Traction control warning lights, VSC warning lights. These lights have been on for 2 years, resulting in check engine light on. I have replaced every sensor possible, fuses, gas cap, and reset the system multiple times but can not get these lights to stay off. Since lights have been on, when driving on a muddy, wet, icy or slippery road way, my steering locks up, the brakes stop working and there is complete loss of vehicle control. All without warning. This is an extreme hazard and very dangerous. This has been on going since 2017 and is still a major problem . It started at around 200,000 miles.

Tl* the contact owns a 2003 toyota sequoia. While driving approximately 70 MPH, the vehicle failed to accelerate when depressing the accelerator pedal. The speed control, vcs, traction control, and sas warning indicators remained illuminated. The failure recurred numerous times. The vehicle was taken to several dealers, but no failure could be found. In addition, the contact stated that the vehicle was taken to an independent mechanic where it was diagnosed that a malfunction of the ecu tracking device failed and needed to be replaced. The vehicle was not repaired. The VIN was not included in the federal safety agency campaign number: 10v176000 (electronic stability control, traction control system). The manufacturer was not made aware of the failure. The approximate failure mileage was 224,000.

Vehicle stability control (vsc), traction control (trac), and antilock brake system (ABS) dash lights continuously illuminated indicating that all systems are off or malfunctioning. Can confirm that the trac, vsc, and ABS are inactive all or most of the time. The ABS intervenes at random under normal braking conditions without cause at low speed (less than 20mph) and makes braking difficult and inconsistent in conditions where ABS is not normally needed. In that situation the brake pedal becomes hard to depress and braking force is inconsistently applied with little control given to the operator in turn extending the braking distance without due cause or warning. After much research online I have found numerous reports stating identical and/or similar observations and experiences. It is my opinion that the problem lies in the vsc control module, a known problematic component on this generation of sequoia and more specifically model year 2003 vehicles. A recall for the vsc system was issued in april/may 2010 upgrading the control logic of the vsc system in certain model year 2003 vehicles. Let it be known that the vehicle in question had the recall work done in june of 2011 which did not remedy the issue as it has been either intermittent or constant since then.

I am experiencing the same vsc problems as I read in the other complaints, along with other electrical issues. Randomly (or so it seems) the vsc, brake lights, drive light and others will go on and off. It has been doing this for about a month now and every time I go to take it in for service, they aren't on and they "can't find anything wrong."

Upon normal driving the vehicle would not accelerate accurately and quickly enough after making a left turn. The vehicle would also randomly illuminate 3 indicator lights when the brake pedal is depressed. The 3 indicators are brake, trac off, vsc off. Before these lights illuminate the vehicle's brake pedal would become very hard to press causing the brake pedal to require much more force applied to it thus causing a decrease in stopping distance which is a very serious safety issue.

The rear window motor and window tracks have rusted completely. The motor has failed and the window tracks are completly rusted away. The window is not unoperable. There is a short in the o2 sensor wiring underneath the vehicle. There is currently a recall on the above vehicle regarding frame rust. I believe that the above complaints are directly related to the rust issues that this vehicle has.
