MY SCION EXPERIENCED LOSS OF STABILITY CONTROL, TRACTION CONTROL AND ANTI-LOCK BRAKES DURING A SNOW STORM IN WINTER 2012. WARNING LIGHTS FOR ABS, BRAKES AND VSC ON THE GAUGE CLUSTER ILLUMINATED AT THAT TIME. WHILE DRIVING AT SLOW SPEED IN THE STORM I REALIZED THAT ABS WAS NOT WORKING. THE WARNING LIGHTS REMAINED LIT FOR ABOUT TWO DAYS, THEN WENT OUT AND DID NOT RETURN UNTIL DECEMBER 2013. MY VEHICLE WAS IN CALIFORNIA DURING THE WINTER OF 2013, AND DID NOT EXPERIENCE ANY LOSS OF ABS, BRAKES, VSC OR TRACTION CONTROL OR ILLUMINATED WARNING LIGHTS. IN DECEMBER 2013 WHILE DRIVING IN A LIGHT SNOW, APPROX 2 INCHES, EXITING A LOCAL HIGHWAY AND APPROACHING A STOP SIGN AT 25 MPH I PUT PRESSURE ON THE BRAKES TO STOP. MY CAR SPUN AROUND 360 DEGREES. I HIT A SNOW BANK AND CAME TO A STOP. THE ENTIRE TIME THE VEHICLE STABILITY SYSTEM DID NOT ACTIVATE. THE THREE WARNING LIGHTS FOR ABS, BRAKES AND VCS ARE NOW CONTINUOSLY LIT. ANTI-LOCK BRAKES, TRACTION CONTROL AND VEHICLE STABILITY CONTROL STILL DO NOT FUNCTION. *TR
