WHEN DRIVING FORWARD OR BACKWARDS AT LOW SPEED BRAKE PEDAL SEEMS LIKE IT LOCKS UP AND IT IS EXTREMELY HARD TO STOP THE VEHICLE I HAD TO PRESS THE PARKING BRAKE A COUPLE TIMES JUST TO GET IT TO STOP

TL* THE CONTACT OWNS A 2015 GMC SIERRA 1500. WHILE DRIVING 10 MPH, THE CONTACT PULLED INTO HIS DRIVEWAY AND HEARD AN ABNORMAL NOISE COMING FROM THE STEERING WHEEL. THE CONTACT TOOK THE VEHICLE TO GARBER BUICK GMC (5255 US-1, FORT PIERCE, FL 34982, (772)467-0835) TO BE DIAGNOSED, BUT THE CAUSE OF THE FAILURE COULD NOT BE DETERMINED. THE FAILURE RECURRED. THE CONTACT TOOK THE VEHICLE BACK TO THE SAME DEALER WHERE IT WAS DIAGNOSED THAT THE RACK AND PINION FAILED AND NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND INFORMED THE CONTACT THAT AN INVESTIGATION WOULD TAKE PLACE TO DETERMINE THE CAUSE OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 27,548.

EXPERIENCED AN UNUSUAL REACTION TO BREAKING. A FEW DAYS LATER I HAD BRAKE WARNING LIGHTS ON THE DASH. TOOK THE VEHICLE TO THE DEALER AND THEY HAD TO REPLACE THE CYLINDER BRAKE MASTER AND THE BRAKE BOOSTER AND ADD NEW FLUID. WHICH I PAID FOR. NOW I SEE THERE MAY BE OTHER ISSUES AS THERE ARE OTHER COMPLAINTS YOU'RE INVESTIGATING. I WANT TO PUT MINE ON RECORD.

BRAKE SYSTEM FAILURE. BRAKE PEDAL WOULD DEPRESS TO THE FLOOR AND STOP WORKING AS THE TRUCK WAS SLOWING DOWN. THIS WOULD HAPPEN IN ALL BRAKING SITUATIONS. I TOOK THE TRUCK TO THE DEALERSHIP AND THEY STATED THE VACUUM PUMP FAILED. $1142.67 FOR REPAIR! NOV 15/ 2018.

I BOUGHT THIS TRUCK IN DEC.2017 SENSE MARCH/ APRIL OF 2018 I HAVE EXPERIENCED AT LEAST 8 TIMES MAYBE MORE AND JUST LAST WEEK. THE BRAKE PEDAL HAD LOST IT'S POWER ASSIST. THIS SEEMS TO HAPPEN IN VERY CLOSE SLOW SPEED TRAFFIC OR IN PARKING LOTS WHEN PARKING. THE WAY I SOLVE THIS PROBLEM IS TO PUT TRUCK IN NEUTRAL AND INCREASE RPM'S OR YOU 2 FEET ON THE BRAKE PEDAL ITHE POWER ASSIST WILL SOON RETURN, THESE SITUATION COULD BE A REAL PROBLEM AT HIGHER SPEEDS. I HAVE CHECKED THE VACUUM BOOSTER FOR LEAKS, BRAKE FLUIL AND DONE A FRONT AND REAR BRAKE JOB. THE WEEK OF NOV. 18 I SAW AN ARTICLE IN THE BOSTON GLOBE ABOUT THIS SPECIFIC PROBLEM AND UNDER INVESTIGATION. I CONTACTED MY LOCAL DEALER CENTRAL BUICK AND GMC IN NORWOOD MA..ON NOV 26.2018 THE SERVICE WRITER SAID HE KNEW NOTHING ABOUT THIS PROBLEM OR COMPLAINTS NOR THE ONGOING INVESTIGATIONS. HIS THOUGHT WAS BRING THE TRUCK IN AND WE WILL CHECK AND REPAIR AT MY EXPENSE. SADLY I WISH HIS RESPONSE WAS DIFFERENT . THANKYOU D.S.M.

AT SLOW SPEED BACKING UP OR MOVING FORWARD, I LOSE POWER ASSIST FOR BRAKING, HAVING TO ALMOST STAND ON THE BRAKES TO STOP. THIS HAPPENS INTERMITTENTLY. STREET OR PARKING LOT.

BRAKES BECOME VERY HARD TO PRESS IN TRAFFIC AND WHILE BACKING UP. THE CONDITION WORSENS WITH MULTIPLE PRESSES OF THE BRAKE PEDAL. THE STOPPING DISTANCE OF THE TRUCK IN INCREASED EVEN WITH INCREASED PRESSURE ON THE PEDAL. THE TRUCK HAS 28,463MI. I CONTACTED A DEALERSHIP AND THEY WILL NOT COVER THIS REPAIR. I HAVE ORDERED THE PARTS AND WILL PERFORM THE REPAIR MYSELF. GM HAS ISSUED A SERVICE BULLETIN ON THIS PIT5361B.

BRAKES APPEAR TO LOSE BOOST WHEN STOPPING. HAVE TO PRESS PEDDLE WITH BOTH FEET. THIS HAS HAPPENED ON THREE SEPARATE OCCASIONS.

AT SLOW SPEEDS FROM A STOP IF YOU LET OFF THE BREAK PEDAL AND IMMEDIATLY REAPPLY THERE SEEMS TO BE EXTREMELY HARD BREAKING. ALMOST IMPOSSIBLE TO STOP THE CAR.
