2014 GMC SIERRA 1500 Complaints

WHEN SLOWING DOWN, THE BRAKE PEDAL ON THE VEHICLE WOULD BECOME HARD TO PRESS. ONCE THE BREAK PEDAL BECAME HARD, IT WOULD TAKE A LONGER DISTANCE TO STOP THE VEHICLE COMPLETELY. IT HAPPENED AT SLOWER SPEEDS, FOR EXAMPLE AS I WAS PULLING INTO A PARKING LOT.

I STARTED MY TRUCK AND A MESSAGE CAME UP THAT SAYS TO SERVICE POWER STEERING AND I AM UNABLE TO TURN MY WHEEL OR DRIVE SAFELY. I KNOW THAT THIS IS A RECALL ON 2014 SIERRA BUT THE DEALERSHIP REFUSES TO FIX MINE

BRAKE PEDAL BECAME HARD AND WAS DIFFICULT TO STOP PROPERLY. I FELT THAT I HAD NO CONTROL OVER THIS VEHICLE. .I BROUGHT THE TRUCK TO VAIL GMC IN MT KISCO ,NY ON SEPT 22, 2017 THEY SAID IT WAS THE VACUUM PUMP AND HAD TO BE REPLACED AT THE COST OF $353.16. THE VEHICLE ONLY HAD 40256 MILES ON IT JUST OUT OF WARRANTY. IT WAS BROUGHT TO MY ATTENTION THAT THIS A REAL PROBLEM WITH THIS ISSUE NATIONALLY. THIS IS A POTENTIALLY A DANGEROUS CONDITION AND IS UNSAFE.THIS BRAKING PROBLEM WAS ON THE THE CITY STREET AND PARKING LOT.

I WAS DRIVING ON THE INTERSTATE AND A MESSAGE STATING "SERVICE STABILITRACK" MESSAGE APPEARS SIMULTANEOUSLY WITH THE CHECK ENGINE LIGHT AND SERVICE TRACTION CONTROL, THE CAR LOSES THE ABILITY TO ACCELERATE AND MAINTAIN SPEED. I KEPT DRIVING BECAUSE THERE WAS NO SAFE PLACE TO STOP, AND AFTER A FEW MILES THE DOOR LOCKS UNLOCKED THEN LOCKED, THE INFO SCREEN FLASHED AND THEN THE ENGINE REVVED AND APPEARED TO DRIVE NORMALLY. SEVERAL MILES LATER IT HAPPENED AGAIN, OVER AND OVER. WHEN I REACHED MY NIEGHBORHOOD THE CAR COMPLETELY POWERED OFF.

MY TRUCK LOST ALL ELECTRICAL POWER WHEN I WAS AT A STOP LIGHT,, I WAS IN DRIVE BUT WAS AT A STOP LIGHT , IT HAPPENED A SECOND TIME AFTER I SHUT IT OFF CAME BACK AND TURNED THE KEY AND THERE WAS NO POWER I WAITED FOR 5 MINUTES AND AL OF SUDDEN ELECTRICAL TURNED ON

WHEN I WAS INVOLVED IN A FRONT IMPACT COLLISION THE DRIVER'S AIRBAG DIDN'T INFLATE. THE PASSENGER SIDE FLOORBOARD HAD SMOKE AND GAS COMING FROM UNDER THE DASH.

"TAKATA RECALL" DRIVING TRUCK DOWN INTERSTATE AND IT JUST CUTOFF NO STEERING NO BREAKS ALL POWER SHUTS OFF. I WAIT TILL TRUCK IS STOOPED AND TRY WIGGING KEY AND MAKE SURE GEARSHIFT IS IN RIGHT POSITION. AFTER A FEW MIN LIGHTS COME ON THE DASH AND THE TRUCK WILL START BACK UP. IT SAYS IN THE NOTIFICATION AREA IN DASH LET DRIVER SIDE WINDOW DOWN AND UP AGAIN. THIS HAS HAPPEN TWICE AND BOTH TIMES I WAS ON A INTERSTATE ALMOST HIT BY CARS BEHIND ME. I WAS DRIVING ABOUT 65 MPH GOING STRAIGHT MOST TIME IT WOULD DO THIS IF I CHANGE LANES.

DROVE MY VEHICLE ABOUT 15 MILES AND PARKED IT IN A PARKING LOT FOR ABOUT 10 MINUTES. WHEN I RETURNED AND BACKED OUT OF THE PARKING SPACE THE BRAKE PEDAL WOULD NOT COMPRESS MUCH AT ALL UNLESS I PUSHED ON IT WITH SOME BODY WEIGHT FOR LEVERAGE AND ONLY THEN THE VEHICLE BARELY STOPPED - WAS TRAVELLING AT A VERY LOW SPEED BUT STILL VERY HARD TO STOP THE VEHICLE. I TRIED TO PUMP THE BRAKE PEDAL, THEN CAREFULLY MOVED THE VEHICLE A COUPLE OF TIMES TO TEST THE BRAKES AND THE CONDITION REPEATED. I THEN PARKED THE VEHICLE AND SHUT OFF THE ENGINE MOMENTARILY. THE CONDITION PERSISTED WHEN I RESTARTED THE VEHICLE. I STARTED TO DRIVE THE VEHICLE SLOWLY AND CAREFULLY IN A LOOP AROUND THE PARKING LOT PUMPING THE BRAKES A COUPLE TIMES AND THE PEDAL FINALLY RETURNED TO NORMAL. HAD I BEEN ON THE HIGHWAY WHEN THIS CONDITION OCCURRED OR HAD I BEEN TOWING OUR 5K-LB TRAILER THE CONSEQUENCES COULD HAVE BEEN CATASTROPHIC. READING ONLINE THE ISSUE APPEARS COMMON IN GM TRUCKS FROM 2014 UP AND THE CAUSE WAS OFTEN A FAILING VACUUM PUMP. I LOCATED A COPY OF A SERVICE BULLETIN PUBLISHED INTERNALLY BY GM DISCUSSING THE ISSUE AND PRESCRIBING A REPAIR PROCEDURE. THE BULLETIN NOTED THAT IF ENGINE OIL ESCAPED PAST THE SEAL(S) OF THE FAILING VACUUM PUMP REPLACEMENT OF THE BRAKE BOOSTER, MASTER CYLINDER, AND VACUUM LINE MAY BE REQUIRED IN ADDITION TO THE PUMP. GIVEN THE APPEARANCE OF THIS AS A COMMON ISSUE, FEAR OF LOSING BRAKES AGAIN, AND FEARING THAT WAITING MAY NECESSITATE OTHER BRAKING COMPONENTS UNDER THE HOOD NEEDING REPLACEMENT IF THE OIL SEEPED THROUGH THE PUMP, I PROMPTLY REPLACED THE VACUUM PUMP. FOLLOWING THE REPAIR PROCEDURE PRESCRIBED IN THE GM BULLETIN THERE WAS NO ENGINE OIL NOTED IN THE VACUUM LINE SO NO FURTHER PARTS WERE REPLACED OTHER THAN THE PUMP AND GASKET. CONDITION HAS NOT REPEATED AFTER REPLACING PUMP 1K MILES AGO. VEHICLE HAD APPROX. 65K MILES WHEN THIS CONDITION OCCURRED.

I HAVE TAKEN MY VEHICLE THREE TIMES TO THE DEALERSHIP FOR THE RADIO SYSTEMS TURNING OFF COMPLETELY, NOT GIVING ACCESS TO RADIO FUNCTIONS, AND STAYS ON AFTER THE VEHICLE IS COMPLETELY TURNED OFF. NOW THE ISSUE IS CROSSING OVER TO THE DRIVER CLUSTER CONTROL MODULE WHERE IT TURNS OFF COMPLETELY AND RESTARTS ON ITS OWN WHILE I'M DRIVING. DEALERSHIP HAS NEVER GIVEN ME A SOLUTION OR HAVE CONTACTED ME SINCE THEN. WHEN I CALLED ABOUT ON GOING ISSUE, THEY STATED THAT THEY CANNOT DO ANYTHING UNLESS THE PROBLEM IS PRESENT WHEN AT THE DEALERSHIP EVEN AFTER I EXPLAINED IT HAPPENS AT RANDOM TIMES. THEY REFUSED TO LISTEN AND LOOK UP PRIOR SERVICE HISTORY. DID PRIOR RESEARCH AND LOCATED AN ARTICLE THAT RADIO AND CLUSTER WERE GOING TO BE PART OF A RECALL BUT GM CLAIMED IT WAS NOT AN ISSUE.

WHWN DRIVING ON HIGHWAY AT 60 MPH - TRIED TO PASS ACCIDENT SCENE TRUCK TAC STARTED REVING. SPEED DROPPED TO 25-30 MPH. PUSHING ACCELORATOR ONLY REVED THE ENGINE MORE WITH NO INCREASE IN SPEED. BURNING SMELL. DEALER UNABLE TO FIND CAUSE. HAPPENED TWICE.
