To me VSC is just a fluff option that drivers have lived without for 100 years or more…After all, it’s just a light on your dash…But if you feel you MUST have this system operating, then it’s off to the dealership …VSC is intertwined with anti-lock brakes, so repairs can become complex and expensive. But for $200-$300 the dealership should be able to diagnose the problem for you and estimate what the repair will cost…
