WHILE DRIVING AT SLOW SPEEDS, THE BRAKE PEDAL BECAME VERY HARD TO PUSH. THIS CAUSED THE TRUCK TO BE DIFFICULT TO STOP, WHICH CAUSED ME TO ALMOST REAR-END THE VEHICLE IN FRONT OF ME. THIS HAS HAPPENED SEVERAL TIMES. IN RESPONSE TO THIS, THE GMC DEALER REPLACED THE VACUUM PUMP.

SERVICE BRAKES
I WAS PULLING A TRAVEL TRAILER AT 55 MILES AN HOUR, I CAME OVER A HILL TO AN INTERSECTION AND I HAD LOST MY BRAKES. I MANAGED TO FINALLY COME TO A STOP. I DISCONNECTED MY TRAILER. I WENT TO A LOCAL GMC DEALERSHIP, AND THEY DID NOT HAVE TIME TO REPAIR MY VEHICLE. I TOOK IT TO AN INDEPENDENT REPAIR SHOP,AND THEY SAID MY VACUUM BRAKE BOOSTER PUMP HAD FAILED. THEY INSTALLED A NEW VACUUM BREAKER BOOSTER PUMP FOR THE NEXT DAY. THIS WAS A VERY DANGEROUS SITUATION, AS I LOST 95% OF MY BREAKING POWER WHILE PULLING MY TRAVEL TRAILER.

WHEN BACKING UP, AFTER REPEATEDLY PRESSING THE BRAKE PEDAL, THE BRAKE PEDAL WENT TO THE FLOOR AND WOULD NOT STOP THE TRUCK. THE TRUCK ROLLED UNCONTROLLABLY DOWN THE DRIVEWAY AND LUCKILY DID NOT HIT ANYONE OR ANYTHING. IT COULD HAVE KILLED SOMEONE THOUGH. THE SAME ISSUE OCCURRED IN A PARKING LOT WHEN BACKING UP IN AN OPEN SPACE. AFTER REPEATED HITTING THE BRAKE PEDAL TO LINE UP THE VEHICLE, THE BRAKES STOPPED WORKING AN I COULD NO LONGER STOP THE TRUCK.

SERVICE BRAKES
FAILURE OF THE BELT DRIVEN VACUUM PUMP WHILE DRIVING CAUSING VERY HARD BRAKING AND ALMOST CAUSED AN ACCIDENT. VACUUM PRESSURE DROPPED OFF AND CAUSED THE PEDAL TO BECOME FIRM. LUCKILY AFTER IT WAS INSPECTED FOR REPAIR THERE WASN'T OIL CONTAMINATION IN THE VACUUM LINE OR BRAKE BOOSTER SO THOSE DID NOT HAVE TO BE REPLACED.

SERVICE BRAKES
I PULLED INTO A PARKING SPOT AND LOST THE ABILITY TO STOP MY TRUCK. THE BRAKES LOCKED UP AND I COULDN'T PUSH DOWN ON THE BRAKE PEDAL HARD ENOUGH TO GET THE TRUCK TO STOP. I WAS GOING SLOW ENOUGH TO USE THE CURB IN THE SPOT FOR IT TO STOP ME FROM HITTING ANYTHING. I HAD MY CAR TOWED TO A REPAIR SHOP AND THEY CONFIRMED THAT THE BRAKE VACUUM PUMP FAILED AND HAD TO BE REPLACED ALONG WITH THE MASTER CYLINDER AND BECAUSE THE VACUUM PUMP WAS THE INITIAL POINT OF FAILURE, THE REPAIR WAS NOT COVERED UNDER MY WARRANTY.*DT VEHICLE REPAIRED *JB

SERVICE BRAKES
I FIRST NOTICED THE PROBLEM WHEN I WAS BACKING DOWN THE RAMP TO LAUNCH MY BOAT. GENERALLY I CAN LIGHTLY TOUCH THE BRAKES AND THE TRUCK WILL STOP IMMEDIATELY. BUT THIS TIME IT DID NOT AND I HAD TO PUMP MY BRAKES MULTIPLE TIMES BEFORE IT FINALLY CAME TO A STOP. I WAS QUIT ALARMED BUT KINDA BLEW IT OFF. THE TRUCK HAD TRAVELED ABOUT SIX FEET FURTHER THAN I HAD ANTICIPATED. ABOUT A WEEK LATER I STOPPED TO GO THROUGH MY GATE AT MY FARM AND WHEN I DROVE THROUGH THE GATE WHICH IS ON A SLIGHT HILL DECLINE IT HAPPENED AGAIN. I WENT TO TOUCH THE BRAKES TO STOP AND ENDED UP PUMPING THE BRAKES VIOLENTLY IN ORDER TO GET THE TRUCK TO STOP. THIS TIME I TRAVELED ABOUT SEVEN OR EIGHT FEET BEFORE COMING TO A FULL STOP. AFTER THIS INCIDENT I WAS CONVINCED TO TAKE IT TO THE DEALERSHIP. IT OCCURRED ONCE MORE DURING THAT TIME. THE DEALERSHIP SAID IT WAS A MALFUNCTION IN THE VACUUM PUMP THAT WORKS OFF OF THE MAIN ENGINE AND OIL FROM THE ENGINE HAD CONTAMINATED THE BRAKING SYSTEM. I HAD TO HAVE REPLACED A PUMP, BOOSTER, CYLINDER, PIPE, AND FLUID FOR A TOTAL OF 1266.33 DOLLARS. THAT INVOICE NUMBER IS 208452. I FEEL THIS IS A SERIOUS SAFETY ISSUE WHEN YOU THINK YOUR VEHICLE IS GOING TO STOP AND IT DOES NOT. THIS CAN CAUSE A PANIC SITUATION!

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.
