2007 Pontiac Grand Prix Brakes Problems

I RECENTLY PURCHASED A USED 2007 PONTIAC GRAND PRIX GT SEDAN. SHORTLY AFTER DRIVING THE VEHICLE OFF OF THE LOT, I WENT TO TURN ONTO A STREET TRAVELING ROUGHLY FIVE TO SEVEN MILES PER HOUR, AND THE TRACTION CONTROL AND ABS SENSOR LIGHT BOTH REGISTERED ACROSS THE SYSTEM INFORMATION SCREEN AND NOTED THAT I NEEDED TO SERVICE THE ABS SYSTEM AND TRACTION CONTROL SYSTEM. I IMMEDIATELY TOOK THE VEHICLE TO MY MECHANIC WHO SUGGESTED THAT WE START LOOKING ONLINE TO SEE IF THERE WERE A RECALL FOR THIS ISSUE. AFTERLOOKING ONLINE, WE NOTED THAT MULTIPLE OTHERS HAVE EXPERIENCED THE EXACT SAME ISSUE. MOST OF THE FIXES THAT WE HAVE SEEN THAT OTHERS HAVE TRIED WE HAVE ALSO TRIED, BUT NOTHING SEEMS TO FIX THE ISSUE. NOW THE TRACTION CONTROL AND ABS SYSTEM LIGHT ARE ON 90 PERCENT OF THE TIME AND IT HAS BECOME AN ISSUE WITH THE BRAKES. AT APPROXIMATELY 12 A.M. THIS MORNING, I TRIED TO STOP THE VEHICLE AND IT WOULD NOT RESPOND TO THE BRAKES. THERE WAS A GRINDING SOUND COMING FROM THE RIGHT SIDE OF THE CAR, ESPECIALLY WHEN I TRIED TO TURN THE WHEEL TO THE LEFT VERY HARD TO AVOID AN ACCIDENT. I WAS ABLE TO GET THE CAR TO STOP BY HITTING THE EMERGENCY BRAKE. AT THE TIME OF THE INCIDENT BOTH THE TRACTION CONTROL AND ABS LIGHTS WERE NOT REGISTERING ON THE SCREEN. NOW THE SERVICE ENGINE SOON LIGHT HAS STARTED TO APPEAR EVERY TIME I START THE CAR. THIS IS THE FIFTH OR SIXTH TIME IN THE LAST MONTH THAT THE BRAKES HAVE NOT RESPONDED. MY MECHANIC AND I ARE BOTH AT OUR WITS END TRYING TO FIGURE THIS ISSUE OUT. IT IS UNSAFE FOR ME TO DRIVE THE VEHICLE AS I NEVER KNOW WHEN THE BRAKES WILL NOT RESPOND. WE ARE LOOKING INTO REPLACING THE ABS MODULE AT THIS POINT AS A VERY LAST RESORT, BUT IT IS EXTREMELY EXPENSIVE. *TR
