Consumer Description

THE VSC SENSOR IS ACTIVATING DURING NORMAL DRIVING CONDITIONS WITHOUT WARNING. THIS IS CAUSING THE VAN TO AGGRESSIVELY APPLY THE BRAKES AND LOSE ACCELERATION. THIS ISSUE MAINLY OCCURS WHEN TURNING DOWN WHILE GOING DOWN HILL, HOWEVER IT HAPPENS RANDOMLY IN OTHER INSTANCES AS WELL. I HAVE BEEN IN SEVERAL LIFE THREATENING INSTANCES WHERE THE BRAKES ARE BEING APPLIED WHILE TRAVELING THROUGH MOUNTAINS WITH LARGE SEMI TRUCKS BEHIND ME.. NEARLY CAUSING SEVERAL ACCIDENTS. MY RESEARCH POINTS TO A FEW THINGS THAT COULD POSSIBLY BE THE CULPRIT: THE YAW SENSOR STEARING WHEEL ROTATIONAL POSITION SENSOR VSC COMPUTER MODULE THIS VIDEO CAPTURES EXACTLY WHAT IS HAPPENING TO MY VEHICLE.
