Here is the latest scoop if you're a Toyota Sequoia owner of 2003 to 2005 model. If you are having some problem with your Sequoia VSC TRAC sensor lights turning on and off and hearing grinding noise when it auto-engage and disengage, please immediately report it to Toyota Corp Customer Relation. This is a common problem that many Sequoia owners have experience. But Toyota will not do a recall on this. Make sure to review your warranty. If you're still within your warranty, that is 3 yrs/36,000 miles, and you're experiencing this problem, TAKE YOUR CAR TO THE DEALER IMMEDIATELY! But before you do, file a complaint to the Customer Experience Center (http://www.toyota.com/about/contact/index.html ) and call the number posted in the page. Make sure that you get a Case# filed. If you have passed your warranty, make sure to file the complaint immediately as well. Toyota knows this is a faulty part and they would only do a recall on them if every Sequoia owner would file a complaint. You can also file this problem to the Better Business Bureau and Local State Consumer agency. If you don't do this, to fix this problem could cost you a lot of money out of your pocket. I am sharing this with everyone because I just experienced this problem with my 2003 Sequoia. And it almost cost me half of my mortgage. The dealer was nice enough to recognize the problem since I filed a complaint and they only charged me with Labor cost. But still, I should have to pay anything at all. Good luck everyone and keep enjoying your Sequoia out there. It's a great SUV despite of the faulty computer part. :)

I am also experiencing vsc/trac problem on my 2003 sequoia. i am past the warranty at 45,000 mi. the dealer "has never seen this problem before" but just happened to have the part in stock and can fix it right away for $1400.00. i filed a complaint with the DOT Office of Defects Notification at www.odi.nhtsa.dot.gov (http://www.odi.nhtsa.dot.gov) and suggest everyone do the same. this is most definitely a safety issue because the vehicle loses all power momentarily. i have seen several complaints on many dif forums. we all need to report this and i am following the advice of agent phish also and really appreciate the help. toyota is usually a great vehicle but this really sucks and is very dangerous!

I am having the same problem on my 2004 with 32,000 miles. It started around 28,000 miles and I am about to take it in. I will let you know what happens.

Sincerely,

I have a similar problem and figured I would post it. My VSC TRAC, VSC OFF and ABS lights come on and stay on, they never go off. I have a '03 Sequoia 4WD LTD. The first visit to a dealer ended with them stating that they could not read any codes, so the VSC computer needs to be replaced, about 1500 total. The second visit to a different dealer found three different codes and said I needed to bring the vehicle back to check the complete braking System. The third visit to a different dealer found the yaw rate sensor is bad, about 750 total. The car is not experiencing any problems, but, the lights stay on.....Sequoia has 86k miles. Anyone offer any advice?

I have had a problem for some time with the lights staying on (ABS VCS Trac Light, Brake Light, etc.) While my car was under warranty it happened periodically and the service department could not isolate this issue. Now since the warranty has expired they told me the yaw rate sensor must be replaced. The cost quoted was about $550 plus the labor of $95 today just for looking. Some of the quotes above seem very expensive. Please complain to Toyota if you have this problem. This 2003 Sequoia is the worst vehicle I have ever had for it to have been so expensive. The first month I had the car it broke down in the mountains because of an air intake sensor issue. A female traveling alone (that is why I bought this car) but I had to depend on the 18 wheeler drivers rather than my new 2003 Sequoia. It only had 3000 miles on it when it failed.
