2002 Chevrolet Impala Electronic Stability Control Esc Traction Control System Problems

THE SERVICE TRACTION SYSTEM AND ABS LIGHT CAME ON INDICATING THE CAR HAD LOST THE ABS FUNCTION. ACCORDING TO THE DEALER THE HYDRAULIC BRAKE FUNCTION WAS SUPPOSED TO STILL WORK. HOWEVER, IF WHAT I EXPERIENCED RECENTLY USING THE HYDRAULIC FUNCTION IS SUPPOSED TO CONSOLE ME OR OFFER BRAKING SECURITY IT HASN'T LEADING ME TO HAVE MY BRAKES WORKED ON AT MIDAS. WHAT LED ME TO MIDAS WAS THE UNNERVING FEELING OF MY RIGHT FRONT BRAKE SHUDDERING AND GRABBING. THEY SAID THE FRONT BRAKES AND PADS WERE FINE BUT THEY DID DO THE REARS. I CALLED GM AND WAS TOLD THERE WAS NO RECALL ON THIS. I THEN WENT TO THE DEALER AND THEY STATED THEY HAD NO SERVICE BULLETIN ON THIS. SINCE THIS IS PART OF THE BRAKING SYSTEM I AM ASTONISHED THAT THIS PROBLEM HAS NOT BEEN RECALLED. I AM NOT THE ONLY CUSTOMER WITH THIS PROBLEM ACCORDING TO MY OWN INTERNET INVESTIGATING. ACCORDING TO CHEVY THIS PROBLEM COULD COST THOUSANDS. THE PROBLEM DOES NOT APPEAR MECHANICAL BUT ELECTRICAL INVOLVING THE ABS SENSORS AND/OR ECB MODULE. *TR
