2016 GMC SIERRA 1500 Complaints

2016 GMC SIERRA- BOUGHT USED HARD SHIFTING NOTED IMMEDIATELY AND SHUTTERING ON INCLINES, TOOK TO DEALERSHIP HAD PART REPLACED- FIXED SHUTTERING BUT NOT HARD SHIFTS- NOW IT NOT ONLY SHIFTS HARD BUT WHILE I WAS TRYING TO STOP AT A DRIVE THROUGH THE BRAKES FAILED- LUNGES FORWARD ALMOST HITTING THE CAR IN FRONT OF US- NEXT DAY I PULLED INTO A PARKING SPOT SAME THING HAPPENED- BRAKES WOULD NOT COMPRESS- STOOD ON THE BRAKE BEFORE IT FINALLY STOPPED- BACKED UP A BIT TO STRAIGHTEN UP AND THE [XXX] THING DID IT AGAIN IN REVERSE. I'M TRAVELING BACK HOME TO ARKANSAS FROM FLORIDA IN A FEW DAYS WITH MY CHILDREN AND I'M SCARED TO DEATH TO DRIVE THIS THING. I CAN'T GET IT LOOKED AT BEFORE WE LEAVE BECAUSE OF THE WEEKEND/ CHRISTMAS BREAK.SERIOUSLY UNSAFE VEHICLE! THERE SHOULD BE RECALLS ON THESE VEHICLES! I'VE READ SO MANY SIMILAR STORIES, WHY HAS THIS NOT BEEN ADDRESSED YET? GMC SHOULD BE ASHAMED. PARTS OF THIS DOCUMENT HAVE BEEN REDACTED TO PROTECT PERSONALLY IDENTIFIABLE INFORMATION PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

I HAVE EXPERIENCED LOSS OF POWER BRAKE BOOST ON NUMEROUS OCCASIONS, SEVERAL TIMES WHILE BACKING MY BOAT TRAILER DOWN THE BOAT RAMP, AND SEVERAL OCCASIONS BACKING UP AT SLOW SPEEDS AND GOING FORWARD AT SLOW SPEEDS (USUALLY LESS THAN 5 MPH). THE BRAKE PEDAL BECOMES VERY HARD TO DEPRESS, AND TRUCK FEELS LIKE IT'S NOT GOING TO STOP UNLESS I APPLY EXTREME PRESSURE. IT HAS BEEN INTERMITTENT. I ASKED MY LOCAL GMC DEALER ABOUT THE ISSUE THIS PAST FALL, AND WAS TOLD THEY COULDN'T DO ANYTHING UNTIL IT FAILED AND COULD BE REPLICATED. I DIDN'T EXPERIENCE IT AGAIN FOR SEVERAL MONTHS, BUT THIS WEEK IT HAS OCCURRED AT LEAST THREE TIMES. I CALLED DEALER TO MAKE AN APPOINTMENT, WHICH THEY DID, BUT THEY AGAIN TOLD ME THAT UNLESS THEY CAN REPLICATE IT, THEY WON'T BE ABLE TO FIX IT. I HAVE RESEARCHED THIS SITE AND HAVE FOUND A NUMBER OF INSTANCES WITH BOTH GMC SIERRA'S AND CHEVROLET SILVERADO'S EXPERIENCING THE EXACT SAME PROBLEM.

PULLING INTO MY GARAGE AT VERY SLOW SPEED, I DEPRESSED THE BRAKE PEDAL AND NOTHING HAPPENED. I HAD TO STAND ON THE BRAKE PEDAL TO PREVENT THE TRUCK FROM GOING THROUGH THE WALL AND INTO THE DINING ROOM. THOUGHT MAYBE THERE WAS SOME AIR IN THE BRAKE FLUID. LOOKED AT THE RESERVOIR AND NOTHING APPEARED OUT OF NORMAL. A COUPLE OF WEEKS LATER, TODAY 12/18/18, WHILE BACKING OUT OF A PARKING SPOT AT AN AUTOZONE, SOMEONE WALKED BEHIND THE TRUCK. AS I PRESSED THE BRAKE PEDAL TO STOP AND ALLOW THEM TO PASS, NOTHING HAPPENED. THE TRUCK KEPT GOING. I HAD TO STAND ON THE PEDAL TO PREVENT MY TRUCK FROM BUMPING INTO THE PEDESTRIAN. BOTH INCIDENTS HAD THE VEHICLE MOVING AT LESS THAN 5 MPH AND IDLE ENGINE POWER.

WHILE DRIVING APPROXIMATELY 45 MPH, THE DRIVER AND PASSENGER SIDE CURTAIN AIR BAGS DEPLOYED. THE CONTACT STOPPED THE VEHICLE IN THE MIDDLE OF THE HIGHWAY UNTIL THE POLICE ARRIVED. THE VEHICLE WAS TOWED TO THE CONTACT'S RESIDENCE. THE VEHICLE WAS TAKEN TO FINNEGAN CHEVROLET (26529 SOUTHWEST FWY, ROSENBERG, TX 77471) WHERE IT WAS DIAGNOSED THAT THE HEADLINER AND SENSORS NEEDED REPLACEMENT. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 47,000.

FAILED SEAL ON 3RD BRAKE LIGHT RESULTING IN COMPLETE REPLACEMENT OF BRAKE LIGHT REQUIRED DUE TO WATER INFILTRATION. HAPPENED IN CAR WASH AFTER OWNING 2YRS 8 MONTHS.

SINCE BUYING THE TRUCK NEW IN 2016 IT HAD A VIBRATION , WHICH GOT WORSE AS YOU INCREASED SPEED, AT HIGHWAY SPEED, 65-75 MPH THE VIBRATION IS SO BAD IT WAS MAKING ME NAUSEOUS. I HAVE TAKEN IT TO THE DEALER SEVERAL TIMES, FIRST BALANCED THE TIRES AND SAID EVERYTHING WAS NORMAL, TRUCK STILL VIBRATING. SEVERAL MORE TRIPS TO THE DEALER WITH THE SAME RESULT.

BRAKE PEDAL BECOMES HARD TO PUSH MAKING STOPPING A PROBLEM. HUGE SAFETY ISSUE. WHILE IN MOTION AT LOW RPM BRAKE PEDAL BECOMES HARD LIMITING THE STOPPING OF THE TRUCK

MY 2016 GMC SIERRA HAS 44,000 MILES ON IT. IN THE LAST 2 WEEKS I HAVE HAD 3 OCCASIONS WHEN TRAVELING AT VERY LOW SPEEDS THE BRAKE PEDAL BECOMES STIFF AND REQUIRES BOTH FEET TO DEPRESS ENOUGH TO GET THE VEHICLE TO STOP. EVEN WHEN COMPLETELY COMPRESSED WITH MY FULL FORCE THE VEHICLE CONTINUED TO ROLL SLOWLY. ONE TIME WAS IN A PARKING LOT AND THE OTHER 2 TIMES WERE AT DRIVE-THRU FAST FOOD SPOTS. BRAKE FUNCTION SEEMS COMPLETELY FINE AT NORMAL OPERATING SPEEDS. A SEARCH OF THE INTERNET LED ME TO FIND SEVERAL FORUMS WITH PEOPLE DESCRIBING THE EXACT SAME SITUATIONS. AT LOW SPEEDS THE BRAKE PEDAL BECOMING EXTREMELY STIFF AND CANNOT BE DEPRESSED MORE THAN 1". I WAS LUCKY TO BE ABLE TO STOP BY PUTTING MY TRUCK INTO NEUTRAL. IF I HAD ROLLED OUT IN CROSS TRAFFIC SOMEONE COULD HAVE BEEN KILLED. THERE ARE WAY TOO MANY STORIES EXACTLY LIKE MINE ALL OVER THE INTERNET FOR THERE NOT TO BE A SIGNIFICANT PROBLEM WITH THE VACUUM PUMP AND OR BRAKE BOOSTER OR SOME OTHER BRAKE SYSTEM COMPONENT ON 2014-2018 GMC PICKUPS AND LARGE SUVS.

VACUUM PUMP FAILED AND REPLACED AT MY OWN EXPENSE. BRAKES WOULD NOT DEPRESS, WERE VERY FIRM AND TRUCK CONTINUED TO ROLL EVEN WITH EXTRA FIRM PRESSURE ON BRAKE PEDDLE.
