WHILE DRIVING MY CAR HIGHWAY SPEED WAS 65MPH, AT THAT RATE OF SPEED MY VEHICLE WAS PICKING UP SPEED AND WHEN I WENT TO PRESS ON MY BRAKES, IT WAS IF I WAS DRIVING ON ICE AND MY CAR WAS SKIDDING. TWO DAYS LATER I STOPPED FOR GAS AND MY CAR WOULDN'T START, AFTER MY 3RD ATTEMPT, IT STUTTERED HARD TIME TURNING OVER. ONCE IT DID I TURNED IT OFF BUT THE CAR WAS STILL RUNNING. I DID THIS SEVERAL TIMES. VERY SCARED TO DRIVE MY CAR BACK HOME BECAUSE I'M OUT OF TOWN. MY LIGHTS SAYS I HAVE LOW RIGHT TIRE PRESSURE BUT I DON'T, IT'S BACK LEFT TIRE FOR SOME ODD REASON. *TR

I WAS DRIVING AND AFTER MAKING A LEFT TURN, MY SERVICE TRACTION CONTROL, SERVICE BRAKE ASSIST, AND ABS LIGHT ALL POPPED ON. IT WENT ON AND OFF FOR MANY DAYS AS I WOULD STOP AND THEN RE-START THE CAR. I FINALLY TOOK IT TO A CHEVY DEALERSHIP AND WAS TOLD THEY TESTED THE FRONT ABS CONNECTOR AND ADJUSTED THE TIMING. LIGHTS AND CODES WENT OFF FOR ABOUT TWO WEEKS THEN POPPED BACK ON UPON MAKING A LEFT TURN. IN ADDITION TO THE LIGHTS AND CODES, THE CAR NOW MAKE A LOUD GRINDING NOISE AND THE CAR STALLS. I HAVE BEEN AT A LIGHT IN THE MIDDLE OF MAKING A TURN WHEN THE CAR WILL STALL AND NOT LET ME TAKE OFF- THE TRACTION CONTROL SYMBOL WILL COME ON AND I WILL BE STUCK TRYING TO ACCELERATE. THIS IS VERY DANGEROUS AS I HAVE ALMOST BEEN HIT FROM BEHIND A FEW TIMES DUE TO NOT BEING ABLE TO ACCELERATE IN A TIMELY FASHION. I HAVE GONE ON CHEVY IMPALA FORUMS LOOKING FOR OTHER DRIVERS WHO MAY HAVE EXPERIENCED THIS ARE THERE ARE A GOOD NUMBER OF THEM. IT SEEMS TO BE AN ELECTRICAL PROBLEM. *JS

SAME INCIDENT TWICE. I AM DRIVING EITHER AT LOW SPEEDS (5 TO 10 MPH) OR AT 30 MPH. THE LIGHT SERVICE STABILITRAK AND BRAKES COMES ON. AFTER I TURN OFF THE CAR, THE WARNING LIGHTS AND THE MESSAGE GO OFF. I TOOK CAR TO DEALERSHIP BUT THEY SAID THEY COULD NOT HELP BECAUSE THE WARNING MESSAGE IS OFF. I HAVE SEEN MESSAGES ACROSS THE INTERNET POSTS THAT OTHER IMPALAS (2012) ARE DOING THE SAME THING. *TR

BRAKES HAVE WHAT I FEEL IS EXCESSIVE AMOUNT OF FADE ESPECIALLY AFTER JUST A FEW STOPS SEEMS TO OCCUR MORE AT SPEEDS OVER 50 MPH. *TR

WHEN STOPPED AT A RED LIGHT THE PEDDLE WOULD SLOWLY DRIFT TOWARDS FLOOR. THE CAR BEGAN TO ROLL AS IF THE BRAKES WERE RELEASING. I APPLIED MORE PRESSURE TO THE PEDAL HALTING THE VEHICLE. I TOOK THE CAR TO A DEALERSHIP AND WAS TOLD IT WAS DUE TO THE LOCATION OF THE MASTER CYLINDER AND GM WAS AWARE OF IT. MY CONCERN IS THAT THIS MAY CAUSE LOSS OF BRAKEING WHEN IN MOTION. *TR
