My wifes truck (2003 with 70K miles) just started doing the same thing. Lights are off when you start the truck and as soon as you start moving, it makes the noise and the lights come on. Any suggestion are highly appreciated. PLEASE HELP!!! Don't have any extra cash to pay dealer to start guessing.My 2003 Sequoia has had the VSC problems 3 times now. The first time at 54K, booster and steering angle sensor replaced. Toyota good willed me a portion of the cost and I paid $957. The second time, at 78k, just a steering angle sensor was replaced and I paid $500. We are on our third time 92K, and the problem is presenting as it did the first time. VSC lights are off in park, but when I put the vehicle into drive and begin to move, there is a quick abrupt jolt, a brief grinding sound, and the lights go on. Has anyone else had this problem repeatedly? Any suggestions on how to deal with Toyota? I am fed up. I bought a Toyota so I wouldn't have problems like this. I know there will problems with a vehicle on occasion - but come on.
