The contact stated while driving at a low rate of speed, an abnormal, grinding noise began to emit from the brake pedal upon depression without warning. The contact had to pump the brake pedal as the pedal depressed to the floorboard before coming to a complete stop. The contact then took the vehicle to an independent mechanic who informed him that the failure was a known issue with this model vehicle. The mechanic informed him that the vehicle might be under recall. The contact then called a local dealer where he was informed that there were no recalls on the vehicle. The manufacturer had yet to be notified of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 275,000.

WHILE DRIVING WITH MY FAMILY IN THE CAR AND WITHOUT WARNING, THE CAR STOPPED MOVING. IN THE MIDDLE OF AN INTERSECTION IT WAS AS IF IT WAS IN NEUTRAL. THIS WAS TERRIFYING, THEN ALL OF A SUDDEN IT FELT LIKE I WAS HIT FROM BEHIND AND THE CAR POPPED INTO GEAR AND SHOT FORWARD. I NOW HAVE NO REVERSE AND UNSURE WHICH GEARS MIGHT WORK, AS I IMMEDIATELY GOT IT HOME. I AM A DISABLED VETERAN ON A LIMITED INCOME AND NO AM FACING POSSIBLY HUGE EXPENSES FOR TRANSMISSION REPAIRS THAT I NOW HAVE READ HAVE BEEN COMPLAINTS ON MY CAR FOR YEARS! I CAN'T UNDERSTAND HOW GM/CHEVROLET DOESN'T SEE TRANSMISSION ISSUES AS A SAFETY PROBLEM. THIS TRANSMISSION HAS HAD WAY TOO MANY COMPLAINTS. HAVING NO WARNING AND THE INABILITY TO BE ABLE TO MOVE THE CAR IN AN INTERSECTION COULD HAVE BEEN CATASTROPHIC!! ALOS WHEN CALLING A LOCAL DEALERSHIP THEY SHOULD BE BETTER INFORMED ABOUT ANY TSB'S AS TO INFORM CONSUMERS. I JUST THANK GOD MY FAMILY IS SAFE, HOWEVER AM NOW OUT OF A CAR. THANKS GENERAL MOTORS/CHEVROLET, LOOKS LIKE YOURE LOSING ANOTHER LOYAL CUSTOMER.
