“When driving under normal conditions the vehicles' vsc will engage. The dashboard lights go off, there is a loud interior beeping sound, the ABS engages, the car slows down drastically at once. The roads are dry. At first this happened while driving normal speed exiting or entering an hwy off/on ramp. Then happened yesterday as I was driving on neighborhood streets at about 25-30 MPH. I could hear a rubbing on the back tires as if the brakes were on.”

While driving at any speed and usually in a turn, the vsc light will flash, the warning beep will beep, and the ABS brakes will automatically be applied and the engine will quickly decelerate. I have almost been rear-ended several times because the van will suddenly decide to decelerate. I have no control over when this happens and no control of the van when it does!”
