My 2003 Toyota Sequoia's trac system is failing which is causing my car to brake automatically without warning. The car has been reliable until now. We were driving at about 35-40mph on a highway when suddenly the car just braked by itself without me stepping on the brakes. Soon after I noticed that the trac and ABS lights were all on inside my dash. I was able to make it home but my family was terrified because we were almost struck from behind. The vehicle is not safe to drive under this condition. I have not been driving it because I can't afford to fix the problem and I don't want to get killed driving it. I am being told that it's $2000-3000 job. I bought the car because I wanted a safe and reliable car but it has now become an unsafe car and a headache. I am being told that I need a skid booster, brake booster and brake module. I think it's all part of the ABS pump assembly. My mfg warranty has expired and my vehicle does have about 78K miles on it which puts me in a bad spot. Please help!

We own a 2003 Toyota Sequoia. The vehicle skid control (vsc) systems is failing. This first occurred shortly after owning the vehicle for 3 years. The system would suddenly activate while moving losing all power and most of the steering control. We reported it to the dealer offered to replace the computer for approx $2000, with no assurance that this would fix the issue. The problem would occur sporadically but now occurs constantly. This is dangerous when driving in traffic in perfect weather conditions.

My ABS, vehicle skid control and trac control system has failed. Trouble codes indicate system failure and will require new ABS, trac and anti skid ECU. I have not had the repair done yet. I am concerned about the safety without these features. I am aware that there are several people having this same issue.

Toyota Sequoia vsc trac lights on. Vehicle shudders when starting from a stop initially. Worried this could be a potential safety risk. Tundrasolutions.com has many other owners of 2003 Sequoia complaints about exact problem.

I own a 2003 Toyota Sequoia SR5 with 95000 miles. Vsc, trac, and ABS lights came on. Dealership said that the codes are faulty ECU. Cost of repair was $1700. The following week lights came back on. This time they tell me it is a faulty speed sensor on the front right. They recalibrated the vehicle and said if it comes back the cost of the repair is $400. Following week, the lights come on, same code for the speed sensor, so I have it replaced. Two days later, the lights are back on. Not certain what will code this time. After reading several posts online, it looks like this is a recurring issue with this vehicle. So, I'm filing a complaint sense there hasn't been a recall.

One day while driving the warning lights for the vsc off and traction control went on, along with the check engine light. At this point we realized that our ABS may have failed and our family was in danger. The brakes now lock and there is a grinding and swaying of the car. We'll be taking it in to be checked, obviously, but are concerned with the imminent safety issues along with the large number of similar complaints by other 2003 Sequoia owners.

The vehicle skid control/ traction control lights are on in my 2003 Toyota Sequoia SR5. When the car is started, these lights are off. When the car is put into drive and accelerated, a beeping noise occurs and the power is lost and there is a horrible grinding noise as if something is stuck in the transmission or brakes. When the car stops, the vsc trac and trac off lights come on and the car operates normally. This is very dangerous when trying to pull from a parking space into traffic. The car practically dies and oncoming cars may not be able to stop in time. I have to wait until the nearest car is quite far away before pulling out and this can take quite a while at high traffic times. I have read internet accounts of others with this same make and model and the same problem. Some have complained that they were almost in accidents when the problem occurred. Unfortunately, the only remedy seems to be to replace the vsc computer which can cost over $1500. Toyota has not seemed to cooperate with customers on this.

The vcs and traction control light came on and the vehicle started to brake by itself. This was a sudden deceleration without warning.

The traction control system on my 2003 Toyota Sequoia has gone out. Periodically the system will act like the vehicle is going into a skid. The vehicle only has 64,000 miles on it. Most of the time when I turn the vehicle on, the vsc system just lights up on the dashboard stating the system is disabled.
