I have a 2001 lexus lx 470 on three different occasions the vsc has activated at a high rate of speed causing loss of control and almost an accident. every time it was on dry roads with nice weather. the vsc light would come on for a brief second and the vsc off light and center differential light would stay on until the vehicle was put in reverse and a loud pop then the lights would go off. during this time the steering would be tight. *tr
