Vsc control light is on and vehicle has less traction control, causing me to drive it slow and very careful to avoid loss of control. The Sequoia model one year previous had an issue, I believe the 2004 model does as well. Also brake replacement occurs to frequently. I replace my brakes make repairs 2-3 yr. The same occured with my Toyota forerunner. Toyota needs to beef up their braking systems. It is a well documented problem for years and years.

The vsc track, trac off and emergency light of my 2004 Toyota Sequoia, came on, on about October, 2009. I took it to the Toyota dealer, they told me that I had to replace, oxygen sensors, a new battery, and skid control computer. Total more than $2000. I was told that if I don't replace the skid control computer, my break system can fail and consequently loose control of the vehicle. It sounded like a major defect and expensive repair and I was puffered as to why there wasn't any recall on such problem. After the car was serviced, the vsc track, track off, and emergency light came on again in less than a week.. this time the computer told them that :there was air in the fuel system. This is their remedy for me: "I need to close and seal the fueling cap after each fueling." I do seal the fuel cap everytime after refuel. I don't recall that I ever miss one time. They reset the system and sent me off. I was wondering if the first repair was ever necessary, maybe the skid control computer never failed. It was just air in the fuel system.

2004 Toyota Sequoia vsc/ABS skid ECU failure. Just told by dealer that this critical safety item is not covered by warranty. The repair cost $1,700. Why is there not a recall on this. There's seems to be plenty of complaints on the internet. Should low income families choose safety versus cost?

In Oct. Of 2007 the emergency brake light, trac light, and vsc lights activated on our 2004 Toyota Sequoia. We brought our SUV in for brake service. On 8/4/08, the same thing happened with the added element of a loud noise and the brakes engaging in a very abrupt manner. This spontaneous braking could potentially result in a rear end or roll over situation should the wrong conditions exist. We brought the vehicle in to a nearby Toyota dealer. The service adivsor informed us that our vsc computer needed replacement. The replacement would cost $1252 for the part alone with a total cost of $1400 to address this malfunction. Research of related problems revealed that the vsc computer seems to be going bad on 2001 and newer Tundra and Sequoias. We contacted regional customer service, who in turn referred us back to the dealer corporate customer service representative. The corporate customer service representative conducted an investigation and indicated that an out of warranty goodwill repair was declined due to the fact that we were not "loyal" Toyota customers. We are the original owners of the vehicle, prior to this Toyota I drove a Toyota 4X4 for over 150,000 miles. This vehicle is the primary vehicle used to Transport my wife and children. I realize that vehicle skid control is not a feature on most vehicles, and it's purpose is to maintain control in a skid situation, but at this point the fact that it is malfunctioning is a liability rather than a benefit.
