VSC Icon Alarm Comes on When Turning on dry roads
We have a 2006 Toyota Sienna. The vehicle has 188,000 miles on it. The VSC icon comes on along with the alarm when driving on dry roads and when turning whether on flat or downhill travel with the brakes grabbing and releasing. The situation is unpredictable. Had it in and the steering angle alignment was re-adjusted. A computer adjustment according to Toyota. Problem started at approximately 170,000. Had 2 adjustments and the problems persists. The unpredictable nature of this condition precludes wife from driving Sienna. She is afraid the situation might occur on slick roads resulting in a accident or loss of control of vehicle. Problem has been reported to NTSHA. Possible solutions?
