2016 GMC Sierra 1500 complaints

(1) THE TRUCK HESITATES AND THE ENGINE ALMOST SHUTS OFF LIKE IT'S NOT GETTING ENOUGH GAS, IT DOES THIS FOR ABOUT THE FIRST 45 MINS. OF STARTUP. (2) THE BATTERY HAS BEEN REPLACED FOR THE SECOND TIME AND EVEN WITH A NEW BATTERY IT SOUNDS LIKE IT'S BARELY GOT ENOUGH POWER TO START THE ENGINE

BRAKE FAILURE - MULTIPLE TIME WHILE DRIVING MY 2016 GMC SIERRA, THE PEDAL HAS GOTTEN HARD & WILL NOT STOP THE CAR. THIS GENERALLY HAPPENS AFTER USING THE BRAKES SEVERAL TIMES QUICKLY. THE BRAKE PEDAL WILL GET HARD & THE TRUCK WILL NOT STOP. LUCKILY I HAVE NOT BEEN INJURED BUT THE PROBLEM IS VERY DANGEROUS & I FEAR FOR MY LIFE WHILE DRIVING THIS TRUCK. THERE IS A TECHNICAL SERVICE BULLETIN ON THE PROBLEM, TSB # PIT5361C, HOWEVER IT IS NOT A SAFETY RECALL. HOW MANY PEOPLE HAVE TO DIE BEFORE THE NHTSA ENFORCES A RECALL?

I WAS WAITING ON THE ONCOMING TRAFFIC SO I COULD MAKE A LEFT TURN. I HAD PLENTY OF TIME TO MAKE MY LEFT TURN IN FRONT OF ONCOMING TRAFFIC, AS I PROCEEDED TO MAKE MY TURN ALL IF A SUDDEN MY STEERING WHEEL LOCKED UP, STABILITY TRAC LIGHT CAME ON, MY POWER LOCKS LOCKED AND UNLOCKED INTERMITTENTLY AND TRUCK ENGINE DIED. I HAD TO RESTART ENGINE AND IT DID IT AGAIN AS I WAS MOVING ATTEMPTING TO FINISH MY TURN. THIS HAPPENS ON A REGULAR BASIS NOW ANYTIME I HAVE TO TURN STEERING WHEEL IT LOCKS UP AND DOES THIS. SOMETIMES IT DOES EVERYTHING I STATED ABOVE BUT ENGINE DOESN'T DIE. THIS IS DANGEROUS. A COUPLE TIMES WHEN IT DOES THIS MY TRUCK DOESN'T HAVE ANY POWER TO START BUT WAIT 30 SECONDS TO A MINUTE, POWER WILL RESTORE AND YOU CAN THEN START IT UP. IT ALMOST SOUNDS EXACTLY WHAT IS HAPPENING THAT THE 2015 GMC 1500 ARE BEING RECALLED. THIS HAPPENS NOW ON A DAILY BASIS.

IN MARCH OF 2018, I BOUGHT MY 2016 GMC SIERRA 1500 Z71 4X4 USED WITH 36,000 MILES ON IT FROM CRAIN KIA OF CONWAY, AR. THE SALESMAN STARTED OFF BY TELLING ME THAT THEY DIDN'T HAVE ANYTHING I WANTED, BUT OF COURSE WHEN I WAS ABOUT TO HEAD OUT THE DOOR, HE RUNS UP TO ME AND TELLS ME THAT HE FOUND ONE THAT HE THINKS I WOULD LIKE, TOLD ME THAT THEY HAD LOST TRACK OF IT ON THEIR LOT AND IT HAD BEEN THERE FOR OVER 100 DAYS. I LIKED WHAT I SAW, IT WAS A GOOD PRICE, AND IT SEEMED LIKE A MECHANICALLY SOUND TRUCK. AFTER ABOUT A COUPLE WEEKS, I BEGAN TO NOTICE THAT I WAS HAVING TO PUMP THE BRAKES JUST TO STOP, BUT DIDN'T SEEM REAL BAD AT THE TIME. THE PROBLEM ONLY WORSENED SO I BROUGHT IT BY A LOCAL GM DEALERSHIP AND BODY SHOP TO SEE IF THEY COULD DIAGNOSE THE ISSUE, WHICH OF COURSE THEY TOLD ME THAT EVERYTHING WAS FINE. I CONTINUED TO DRIVE IT AND WHEN I WOULDN'T PUMP THE BRAKES, THEY BEGAN GLIDING, ALMOST LIKE I WAS TRYING TO STOP ON ICE BEFORE THEY WOULD ACTUALLY COME TO A COMPLETE STOP. I HAD TWO INCIDENTS' REGARDING THIS ISSUE WITH THE BRAKES WITHIN TWO MONTHS OF EACH OTHER. THE FIRST ON JULY 7, 2018: I WAS AT A STOP SIGN, COMPLETELY STOPPED. I WAS HEADING LEFT AT A THREE WAY INTERSECTION AND THERE WAS A CAR TURNING RIGHT SLOWLY ONTO THE STREET THAT I WAS LEAVING, SO I BARELY LIFTED MY FOOT OFF THE BRAKE TO MAKE MY LEFT TURN WHEN THE CAR DECIDED THAT THEY WERE GONNA GO STRAIGHT. I IMMEDIATELY SLAMMED ON THE BRAKES, BUT THE TRUCK JUST KEPT GOING FOR ANOTHER FEW FEET UNTIL THE BRAKES

THE SECOND INCIDENT ON SEPTEMBER 1, 2018: 2016 GMC SIERRA 1500 Z71 4X4 CC I WAS SPEEDING UP TO MERGE ONTO A BUSY HIGHWAY IN DENVER, HEADED TO THE MOUNTAINS TO TAKE MY WIFE AND THREE BOYS CAMPING. A CAR IN FRONT OF US HAD BEGAN SLOWING DOWN, SO I BEGAN SLOWING DOWN, THEY SLAMMED ON THEIR BRAKES, SO I SLAMMED ON MINE. THE ONLY DIFFERENCE BETWEEN OUR VEHICLES BESIDES SIZE WAS THAT THEY CAME TO A COMPLETE STOP, AS SOON AS I SLAMMED ON MY BRAKES, THE TRUCK JUST GLIDED ON THE PAVEMENT AS IF IT WERE A SHEET OF ICE. THE ONLY THING TO STOP US WAS THE BACK OF THEIR VEHICLE! WE GOT A RENTAL TRUCK AND CARRIED ON WITH OUR CAMPING TRIP. AS WE DROVE PAST THE ACCIDENT SCENE SLOWLY HOURS LATER TO HEAD BACK TOWARDS THE MOUNTAINS, (TRAFFIC WAS MUCH LIGHTER) WE NOTICED THAT THE SKID MARKS FROM MY TRUCK WERE STRAIGHT WITH NO BREAKS IN THE SKID LINES, WHICH TO MY KNOWLEDGE INDICATES THAT THE ABS SYSTEM WAS NOT WORKING PROPERLY. I NEVER HAD ANY INDICATOR LIGHTS SHOW UP ON THE DASH. AFTER THAT ACCIDENT, MY WIFE AND I CONDUCTED A LOT OF RESEARCH, COME TO FIND OUT THAT GM TRUCKS HAD MULTIPLE COMPLAINTS WITH THEIR BRAKES, WISH I HAD DONE MY RESEARCH FIRST.

AT LOW RPM,'S AND AT LOW SPEED THE VACUUM ASSIST PUMP CANNOT SUPPLY ENOUGH ASSIST PRESSURE TO THE BRAKES, THIS DOES NOT LET THE POWER BRAKES WORK AS THEY ARE DESIGNED. WHEN THIS HAPPENS, MOSTLY WHEN BACKING A TRAILER UP BUT ALSO WHEN GOING FORWARD AT SLOW SPEEDS, THERE IS NO POWER ASSIST BRAKES AND A TYPE OF MANUAL BRAKE EXISTS. THIS TYPE OF MANUAL BRAKE REQUIRES MAXIMUM LEG PRESSURE IS REQUIRED TO SLOW DOWN AND/OR STOP, AND WHEN PRESSURE IS APPLIED THERE IS A TIME LAG FOR PRESSURE TO BE APPLIED SO THAT THE VEHICLE STOPS.THIS SAME PROBLEM OCCURS WITH NO TRAILER LOAD INVOLVED AND THE VEHICLE IS GOING SLOW. IT IS A DANGEROUS SITUATION WHEN ENTERING TRAFFIC AT A PERPENDICULAR ANGLE. OTHER COMPLAINTS HAVE BEEN MADE REGARDING THE SAME PROBLEM.

THE BRAKES ON MY 2016 GMC SIERRA 1500 WITH ONLY 31,700 MILES EXHIBITED A HARD BRAKE PETAL AND THE VEHICLE WOULD NOT STOP. THIS HAPPEND AT SLOW SPEEDS WHILE ATTEMPING TO STOP IN PARKING SPACES AND AT RED LIGHTS ON LOCAL ROADS.MOST FRIGHTENING WAS WHILE BACK MY TRUCK AND BOAT INTO A BOAT RAMP THE BRAKES WOULD NOT STOP THE VEHICLE! I BROUGHT THE TRUCK TO THE LOCAL DEALER WHO REPLACED THE BRAKE BOOSTER & THE VACCUM PUMP. I QUESTIONED IF THERE WERE ANY SERVICE BULLETINS AND I WAS TOLD THERE WERE NONE. FEARING THIS COULD HAPPEN AGAIN , I SEARCHED ON LINE AND FOUND OTHER COMPLAINTS EFFECTING NOT ONLY MY MAKE AND MODEL YEAR BUT OTHER GM/GMC MODELS AND YEARS. I ALSO FOUND A TEXAS LAWSUIT WHERE THE PLAITIFFS EXPERIENCE WAS VERY SIMILIAR TO MINE. I CONTACTED GMC CUSTOMER SUPPORT TO LODGE MY COMPLAINT AND REQUESTED AN EXTENSION TO MY BUMPER TO BUMPER WARRANTY . I WAS INSTRUCTED TO CONTACT MY LOCAL DEALER TO PURCHASE AND EXTENDED WARRANTY. THEY WENT ON TO SAY THERE ARE NO SERVICE BULLETINS OR RECALLS FOR THIS ISSUE FOR MY VEHICLE.... THIS NEEDS TO BE INVESTIGATED AS I AM OF THE OPINION THAT THIS IS A SAFTEY ISSUE THAT IS NOT BEING ADDRESSED PROPERLY. A VEHICE WITH LESS THAN 32,000 MILES SHOULD NOT BE HAVING THIS TYPE OF DANGEROUS PROBLEM . I'M OF THE BELIEF THERE IS A DEFECT SOMEWHERE THAT NEEDS TO BE FIXED BASED ON THE COMPLAINTS I'M SEEING FROM OTHERS ONLINE.

VEHICLE INVOLVED IN A REAR END COLLISION AND PUSHED INTO A VEHICLE IN FRONT CAUSING BOTH FRONT AND REAR DAMAGE, AIRBAG CAME OUT OF INFLATER BUT DID NOT DEPLOY

WHILE DRIVING AT SLOW SPEEDS THE BREAK PEDAL WILL NOT DEPRESS. THE PEDAL SEEMS TO GET STUCK. WHEN THIS HAPPENS IT IS DIFFICULT TO COME TO A COMPLETE STOP.

TL* THE CONTACT OWNS A 2016 GMC SIERRA 1500. THE CONTACT STATED THAT THE AIR CONDITIONING WAS BLOWING OUT HOT AIR, WHICH FOGGED UP THE WINDSHIELD AND MADE IT DIFFICULT TO SEE WHILE DRIVING. THE CONTACT HAD TO ROLL DOWN THE WINDOWS IN ORDER TO SEE THE ROAD. THE VEHICLE WAS TAKEN TO GOLD STAR BUICK GMC (1980 N DAVIS RD, SALINAS, CA, (831) 240-4859) FOR REPAIRS.

WE HAVE VIOLENT SHIMMY/SHAKING ISSUES WITH OUR TRUCK AND HAVE SINCE WE GOT IT BRAND NEW. WE HAVE TAKEN IT TO THE DEALER 5 TIMES AND EVEN HAD THE DEALER WITNESS THE SHAKING THE LAST TIME WHILE ON A TEST DRIVE. THEY REPLACED THE TORQUE CONVERTER, REBALANCED THE WHEELS, AND ROTATED THE TIRES AND THE PROBLEM CONTINUES TO HAPPEN REPEATEDLY. WE DO NOT FEEL SAFE DRIVING THIS TRUCK ANY LONGER AS IT HAPPENS AT SPEEDS ABOVE 40MPH. THE DEALER SAYS THEY CAN'T FIX IT IF THEY DON'T KNOW WHAT IS WRONG.

PLEASE MAKE GM RESOLVE THE ISSUES WITH THE 8 SPEED TRANSMISSIONS IN THE TRUCKS. 2016 SLT Z71. I PURCHASED THE TRUCK NEW. IT'S NEVER SHIFTED PROPERLY. HESITATIONS, CLUNKING, JERKING, SHUTTER, HARD DOWN SHIFTS.... EVERYTIME I TAKE IT IN, THEY SAY IT'S DUE FOR AN UPDATE. THE TRUCK HAS HAD 4 UPDATES AND NONE OF THEM HAVE FIXED A THING. I HAD IT IN BEFORE THE 36,000 MILE BUMPER TO BUMPER WARRANTY WAS UP AND WAS TOLD IT WAS UP TO DATE. THEN LAST WEEK, I TOOK IT IN AND WAS TOLD IT WAS "SEVERAL UPDATES BEHIND." (54,XXX) MILES. TO TOP IT OFF, GENERAL MOTORS WOULDN'T PAY FOR THE $400 UPDATE, WHICH DIDN'T FIX ANYTHING AT ALL!!! THE TRUCK JERKED BEFORE WE GOT A BLOCK FROM THE DEALERSHIP. GM SAYS THAT EVEN THOUGH THE TRUCK IS STILL UNDER A FACTORY 60,000 MILE POWERTRAIN WARRANTY, TRANSMISSION UPDATES AREN'T COVERED. THE 120,000 EXTENDED WARRANTY WOULDN'T COVER IT BECAUSE THEY SAY IT SHOULD BE COVERED UNDER THE FACTORY POWERTRAIN WARRANTY! I ABSOLUTELY LOVE THE TRUCK OTHER THAN THE JUNK TRANSMISSION IN IT. I DON'T THINK IT'S SAFE OR MUCH FUN HAVING A VEHICLE THAT STARTS TO GO THEN FALLS FLAT ON ITS FACE FOR A FEW SECONDS BEFORE SLAMMING INTO THE NEXT GEAR. THIS IS A MAJOR PROBLEM WITH A HUGE NUMBER OF TRUCKS. DON'T BELIEVE ME? GOOGLE "2016 SIERRA TRANSMISSION ISSUE" OR ANYTHING OF THE SORT. YOU'LL SEE. I'M REALLY NOT ASKING FOR MUCH. I DIDN'T WANT TO PUT MY FAMILY IN A POTENTIALLY UNSAFE VEHICLE.....YET HERE WE ARE. LIKE I SAID, I'M NOT ASKING FOR MUCH. ALL I WANT IS FOR MY TRUCK TO SHIFT

TL* THE CONTACT OWNS A 2016 GMC SIERRA 1500. WHILE THE VEHICLE WAS STATIONARY, THE DRIVER'S SEAT BECAME LOOSE AND SHIFTED TOWARDS THE STEERING WHEEL AFTER SHIFTING GEARS. SUNRISE PONTIAC IN MEMPHIS, TENNESSEE WAS MADE AWARE OF THE FAILURE AND UPDATED THE FIRMWARE IN THE VEHICLE. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 60,000.

ON TWO SEPARATE OCCURRENCES, W/ FAMILY IN THE VEHICLE, STARTING SPEED AT APPROX. 35MPH, THE ACCELERATOR (GAS PEDAL) STUCK TO THE FLOOR DURING THE PROCESS OF PASSING ANOTHER VEHICLE DURING CITY STREET DRIVING. TOP SPEED GOT TO APPROX. 55MPH, W/ STOP LIGHTS FAST APPROACHING. THE PEDAL SIMPLY WOULD NOT RELEASE FROM FULL THROTTLE UNTIL AFTER THE VEHICLE FINALLY CAME TO COMPLETE STOP WITH BRAKES APPLIED, SHIFTER TO NEUTRAL POSITION, SLAMMING THE SHIFTER TO PARK, AND IGNITION WAS TURNED OFF! HAD TO TAKE IMMEDIATE AND DECISIVE EMERGENCY ACTIONS DURING BOTH SITUATIONS! THE FIRST TIME IT OCCURRED, THOUGHT PERHAPS THE RUBBER FLOOR MAT MAY HAVE CONTRIBUTED TO THIS EVENT; HOWEVER, DRIVER SIDE FLOOR MAT WAS IMMEDIATELY REMOVED. SEVERAL DAYS LATER, DURING SIMILAR OPERATIONS, THE ACCELERATOR (GAS PEDAL) AGAIN STUCK TO THE FLOOR BOARD IN FULL ACCELERATION MODE W/ FAMILY IN THE VEHICLE! CURRENTLY HAVE APPOINTMENT SET-UP AT A HUNTSVILLE, AL. GMC DEALERSHIP. THIS TRUCK WAS PURCHASED BRAND NEW AT LAURA BUICK IN COLLINSVILLE, IL. ALTHOUGH I REALIZE THERE ARE OTHER GMC CUSTOMERS; NOT SURE WHY THIS HUNTSVILLE, AL DEALERSHIP WOULD NOT WORK ME IN SOONER. THIS VEHICLE HAS APPROX. 49K MILES AND SHOULD STILL HAVE WARRANTY REMAINING UNTIL 68K MILES. GMC SERVICE DEPARTMENT REP. STATED, "MONDAY 26, FEBRUARY IS FIRST DATE AVAILABLE."

TL* THE CONTACT OWNS A 2016 GMC SIERRA 1500. WHILE DRIVING APPROXIMATELY 60 MPH, THE HEADLIGHTS FAILED TO ILLUMINATE THE ROADWAY. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. A LOCAL DEALER WAS CONTACTED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND INFORMED THE CONTACT THAT THE HEADLIGHTS WERE WORKING ACCORDING TO SPECIFICATIONS. THE FAILURE MILEAGE AND VIN WERE UNKNOWN. *TT *AS

VACUUM PUMP FAILURE. THE TRUCK HAD THE VACUUM PUMP FAIL AFTER ONLY 56,XXX MILES. THE PUMP FAILED AND CAUSE ME A HARD BRAKE PEDAL WHILE COMING TO A STOP. THE PART INTERNALLY FAILED AND WAS NOT PRODUCING ENOUGH VACUUM TO SUPPLY THE BRAKE BOOSTER. AFTER DISCUSSING THIS WITH THE DEALER IT WAS A COMMON PROBLEM AND NOT COVERED BY WARRANTY.

RECALL# 42190 UPPER CONTROL ARM BROKE ON MY GMC SIERRA 1500. I WAS DRIVING OUT OF A CHURCH PARKING LOT AND MADE A LEFT TURN ON TO A CITY STREET AND MY RIGHT FRONT PASSENGER TIRE FELL OFF. I CONTACTED GM WARRANTY DEPARTMENT AND GOT IT TOWED TO DALTON MOTORS IN MARIANNA, AR. THE TECHNICIAN STATED THAT I HAD BEEN IN AN ACCIDENT. THAT WASN'T TRUE. HE CALLED SUNRISE GMC IN MEMPHIS, TN OFF COVINGTON PIKE AND TOLD THEM ALL TYPES OF LIES AND TO NOT FIX IT. I TOOK IT TO SUNRISE ON NOVEMBER 20, 2017 AND THE TECHNICIAN LOOKED AT IT FOR 5 SECONDS AND SAID I HIT A POT HOLE AND THAT HE WOULD NOT FIX IT OR HONOR MY WARRANTY. A POT HOLE DIDN'T CAUSE THIS PROBLEM. I CURRENTLY HAVE A 5 YEAR 36,000 MILE WARRANTY THAT COVERS THIS PROBLEM. THERE IS ALSO A CURRENT RECALL ON THIS ISSUE AND I WAS NOT NOTIFIED WHEN I PURCHASED THE VEHICLE. I HAD TO LOOK IT UP ON MY OWN.

TL* THE CONTACT OWNS A 2016 GMC SIERRA 1500. WHILE INSPECTING THE VEHICLE, IT WAS DISCOVERED THAT THE PROTECTIVE RUST PROOFING COATING WAS COMING OFF, AND RUST AND CORROSION WERE PRESENT ON THE SUBFRAME OF THE VEHICLE. THE CAUSE OF THE FAILURE WAS NOT DIAGNOSED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER AND LOCAL DEALER WERE NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 5,200.

POWER STEERING KEEPS GOING OUT FOR A SHORT PERIOD TIME THEN STARTS AGAIN ,CHECK POWER STEERING LIGHT COMES ON THEN GOES OFF. THIS HAS HAPPEN ABOUT 20 TIMES IN LESS THAN YEAR AND HALF WHILE DRIVING IN CITY AND HIGHWAY AND PARKING LOT. DEALER SAYS THEY CAN'T FIND ANYTHING

I HAVE A 2016 GMC SIERRA 1500 5.3L. I'VE BROUGHT THE TRUCK DOWN TO THE DEALER 4 TIMES NOW BECAUSE THE AC DOESN'T BLOW COLD AIR. THE AC STOPPED WORKING AGAIN THIS WEEK WITH THE TRUCK ONLY HAVING 2,800 MILES ON IT. I CALLED GMC DIRECTLY (NOT THE DEALER) BECAUSE I DON'T WANT TO BRING THE TRUCK DOWN TO THE DEALER FOR THE 5TH TIME FOR THE SAME ISSUE. IT'S 85+ DEGREES NOW WHERE I LIVE AND DRIVING WITHOUT AC IS UNBEARABLE, ESPECIALLY WHEN IN TRAFFIC. GM SENT ME AN E-MAIL INFORMING ME THE AC CONDENSER IS FAULTY BY DESIGN AND A 'REDESIGN' HAS BEEN CREATED. THE PART IS ON "NATIONAL BACK ORDER" WITH NO ETA. THEY SAID IT COULD BE 4-6 WEEKS WHICH MEANS DRIVING MY TRUCK WITHOUT AC IS VERY UNCOMFORTABLE AND NOT AN OPTION WITH CHILDREN IN THE TRUCK WHO CAN'T WITHSTAND THE HEAT. I'M READING ON VARIOUS FORUMS THAT PEOPLE HAVE BEEN WAITING SINCE MARCH (4 MONTHS) FOR THE NEW CONDENSER TO COME IN.

VEHICLE HAS A VIBRATION THAT GETS WORSE AS SPEED INCREASES.GM NOT BEING ABLE TO DETERMINE THE ORIGIN OF THE PROBLEM HAS SAID IT IS NOT A SAFETY ISSUE.THE VERY FACT THAT THEY CANNOT FIND THE ORIGIN MAKES IT A POTENTIAL SAFETY ISSUE. AFTER MUCH DIAGNOSTIC WORK AND PARTS REPLACEMENT STILL NO ANSWER.

WIPERS DO NOT MOVE FAST ENOUGH TO CLEAR THE RAIN FROM THE WINDSHIELD MAKING IT IMPOSSIBLE TO SEE 5 FEET IN FRONT OF YOU. THIS IS A SAFETY ISSUE. THE BLADES NEED TO MOVE MORE QUICKLY TO CLEAR THE WINDSHIELD MAKING IT SAFE TO OPERATE WHEN IT RAINS.

8 SPEED TRANSMISSION BUCKS, HESITATES, LURCHES FORWARD, CLUNKS, WHILE IN DRIVE. THE CONTINENTAL TIRES ARE CUPPING, WHICH GM SAYS IS CHARACTERISTIC OF THE BRAND. THE TRUCK VIBRATES WHILE AT 25MPH, AROUND 50MPHM AND 65-75MPH. WHILE IN AWD/4WD AT 30 AND 50MPH, THE DRIVELINE MAKES A WHINING NOISE AND VIBRATES SOMETIMES.

GM 8 SPEED TRANSMISSION IS FULL OF PROBLEM. IT CONSTANTLY HESITATES, HANG GEARS, BUCKS, AND POSES VARIOUS SAFETY CONCERNS. FOR INSTANCE IF MERGING ONTO THE HIGHWAY THE TRANSMISSION WILL HESITATE AND THE TRUCK WILL BE UNRESPONSIVE TO GAS PEDAL INPUT FOR A PERIOD OF TIME SOMETIMES UP TO 12 SECS. THIS HESITATION CAUSES A SAFETY CONCERN WHEN ATTEMPTING TO MERGE INTO TRAFFIC. GM ACKNOWLEDGES THESE CONCERNS BUT STATES THAT IT IS OPERATING AS DESIGNED BUT ARE WORKING ON SOFTWARE UPDATES TO IMPROVE TRANSMISSION PERFORMANCE. THIS HAS BEEN A CONSTANT ISSUE SINCE I PURCHASED THE TRUCK.

REAR BENCH SEAT HEADRESTS DO NOT STAY LOCKED IN POSITION WHEN RAISED. LEANING HEAD BACK ONTO HEADREST CAUSES THEM TO LOWER WHICH COULD RESULT IN INJURY TO THE BASE OF THE NECK OR HEAD DURING A CRASH. ALSO, HEADRESTS ARE TOO LOW FOR FULL SIZE ADULTS TO ADEQUATELY PROTECT THE HEAD/NECK FROM HITTING GLASS REAR WINDOW DURING HARD STOP OR CRASH. TOOK VEHICLE TO DEALERSHIP TO INVESTIGATE. DEALER INDICATED ALL 2016/2017 MODEL TRUCKS ON THEIR LOT FUNCTION THIS WAY. ASKED TO REPORT IT HERE. REAR SEAT HEADRESTS NEED TO BE RECALLED TO ALLOW FOR A LOCKING MECHANISM TO BE INSTALLED. REAR SEAT HEADREST DESIGN NEEDS UPDATED TO INCREASE BACK OF HEAD/NECK PROTECTION HEIGHTS DURING CRASH.

ON 20 MARCH 17, I WAS TRAVELING DOWN A COUNTRY ROAD WHEN A DOG ENTERED THE ROADWAY. I SWERVED RIGHT AND WAS NOT ABLE TO CORRECT, WITHOUT THE POSSIBILITY OF OVER STEERING AND POSSIBILITY ROLLING MY TRUCK. I WENT THROUGH A SMALL DITCH MY SIDE AIR BAGS DEPLOYED. I WAS ABLE TO GET BACK ON THE ROAD.I STOPPED THE TRUCK AND COULD NOT SEE ANY DAMAGE. I RETURNED TO MY FRIENDS HOUSE AND CONTACTED MY INSURANCE,TOW COMPANY AND THE LOCAL SHERIFF DEPT, NOBODY INCLUDING THE REPAIR FACILITY COULD DETECT ANY DAMAGE ASIDE OF THE AIR BAG DEPLOYMENT. MY INSURANCE ADJUSTER AND THE SERVICE FACILITY BOTH EXPRESSED THEY ARE FAMILIAR OF SUCH ACCIDENTAL SIDE AIR BAG DEPLOYMENTS ON THIS VEHICLE.,

WHEN THE PEDDLES ARE RAISED AND YOU STEP ON THE BRAKE YOU COULD BE PUSHING THE GAS AND BRAKE AT THE SAME TIME. WHEN THE PEDDLES ARE LOWERED THIS DOES NOT HAPPEN. A LOT OF PEOPLE STEP ON THE SIDE OF THE BRAKE AND IT HAPPENS ONLY WHEN RAISED.

PERIODICALLY 3 TIMES A WEEK, WHILE DRIVING, THE STABILIZTRAK ILLUMINATES AND DRIVABILITY DECLINES, ENGINE CHECK LIGHT ILLUMS, THE GEAR REMAINS IN A LOW GEAR WITHOUT SHIFTING. TURN THE IGNITION OFF FOR A COUPLE SECONDS AND IT CLEARS AND THE ENGINE LIGHT GOES OUT AFTER 25-35 MILES. SOMETIME IT DOESN'T RESET AFTER 3 ATTEMPTS OF TURNING OFF AND ON THE IGNITION. THE CODES ARE P0700 A U0100 WITH OTHERS WHEN DEALERSHIP ANALYZED. THREE TIMES IT WAS IN THE GMC SHOP AND THREE TIMES GIVING BACK AND PROBLEM STILL EXISTED. I RECORDED ON VIDEO AND GAVE IT TO THE DEALERSHIP AS PROOF.

THE DRIVER SEAT DOES NOT GO UP AND DOWN.THIS IS A BIG SAFETY FEATURE PURCHASED NEW I CAN BARLEY SEE OVER STEERING WHEEL WHY WOULD YOU MAKE SEATSLIKE THIS

ELECTRICAL ISSUE CAUSING SOUND SYSTEM, REAR CAMERA AND RADIO TO SHUT DOWN COMPLETELY. ISSUE STARTED 2 WEEKS AFTER PURCHASE. VEHICLE HAS BEEN SERVICE SEVERAL TIMES BUT ISSUE HAS NOT BEEN RESOLVE.

THE QUALITY/PRECISION ISSUES I AM HAVING WITH MY VEHICLE ARE ISSUES THAT SHOULD NOT BE HAPPENING TO A $50,000 VEHICLE. THE ENGINE HAS A ROUGH IDLE WHEN IT IS FIRST STARTED UP. AFTER THE VEHICLE WARMS UP THE ROUGH IDLE GETS WORSE. IT GETS EVEN WORSE WHILE I AM DRIVING IT AND I COME TO A STOP SIGN OR RED LIGHT. THE ROUGH IDLE VIBRATES THE ENTIRE VEHICLE. THE ROUGH IDLE IS AT ITS WORSE WHEN I STOP AFTER HAVING DRIVEN ON THE HIGHWAY FOR SEVERAL HOURS. I BOUGHT THIS NEW VEHICLE BECAUSE MY PREVIOUS VEHICLE WAS TOTALED IN AN AUTOMOBILE ACCIDENT WHEN SOMEONE T-BONED ME IN MY 2007 GMC YUKON XL. MY YUKON HAD APPROXIMATELY 200,000 MILES AND DID NOT HAVE A ROUGH IDLE OR VIBRATE LIKE MY 2016 SIERRA DOES. I KNOW THE TECHNOLOGY IS TOTALLY DIFFERENT THAN MY 2007 BUT IT SHOULD AT LEAST IDLE AS GOOD AS IF NOT BETTER THAN MY 2007 YUKON THAT HAD 200,000 MILES, BUT IT DOES NOT. THERE IS ALSO A HESITATION WHEN ACCELERATING FROM A STOP THAT IS GETTING WORSE WITH EVERY ADDITIONAL MILE I PUT ON THE VEHICLE. THE HESITATION IS SO BAD AT TIMES I WORRY THE ENGINE IS GOING TO STALL OUT ON ME. IT FEELS/SOUNDS LIKE THE CYLINDERS ARE LOADING UP WITH TOO MUCH FUEL AND ARE NOT FIRING CORRECTLY. THE STOICHIOMETRIC RATIO IS NOT CORRECT. AT TIMES, IT FEELS LIKE A MISS. MY FUEL MILEAGE IS ALSO DECREASING. IN THE VERY BEGINNING I WAS AVERAGING AROUND 19 MILES PER GALLON AND NOW I AM AVERAGING AROUND 17 MILES PER GALLON. I HAVE TRIED DIFFERENT OCTANE LEVELS OF MOSTLY SUNOCO AND BP FUELS WITH NO NOTICEABLE CHANGE IN

I PURCHASED MY 2016 GMC SIERRA SLE DOUBLE CAB ON 9/13/2016. MY TRUCK BEGINS TO VIBRATE/SHAKE AT 40 MPH AND GETS PROGRESSIVELY WORSE TO 70 MPH. THE SHAKE CAN BE FELT IN THE DRIVERS SEAT AND FLOOR. THE CENTER CONSOLE SHAKES AND SHUDDERS MAKING ME FEEL NAUSEOUS AND DIZZY WHILE DRIVING AT HWY SPEEDS. I RETURNED THE TRUCK TO THE DEALER WITHIN THE FIRST 500 MILES. THE WHEELS AND TIRES WHERE FORCED BALANCED WITH NO RELIEF AND THEN ALL FOUR TIRES WERE REPLACED. THE WHEELS AND TIRES I PURCHASED WITH THE VEHICLE WERE A DEALER ADD OF GM 22" WHEELS AND TIRES. THE VIBRATION WAS NOT AS APPARENT AFTER THE NEW TIRES WERE PUT ON BUT NOW THAT I HAVE PUT AN ADDITIONAL 1700 MILES ON THE TRUCK, THE VIBRATION AND SHAKE IS BACK AS ORIGINALLY REPORTED. DURING A 3 HOUR ROAD TRIP ON 11/2/2016 I HAD TO STOP AND LET MY PASSENGER CONTINUE THE TRIP BECAUSE I WAS ILL FROM THE SHAKING AND VIBRATIONS. MY SALES PERSON INITIALLY TOLD ME THAT WHAT I WAS EXPERIENCING WAS HOW 22" WHEELS FEEL. I HAD A 2012 SILVERADO LT Z71 AND A 2014 SILVERADO LT THAT HAD LARGE WHEELS AND I DID NOT HAVE. ANY SHAKING OR VIBRATIONS. I HAVE MADE ANOTHER APPOINTMENT WITH ANOTHER DEALER TO SEEK RELIEF. *TR

THE 2016 GMC SIERRA HAS A CONSTANT VIBRATION WHICH IS FELT THROUGH THE SEATS AND THE STEERING WHEEL. THE CONDITION IS IDENTICAL TO THOSE SUBMITTED FOR THE 2014 AND 2015 GMC AND CHEVROLET MODELS

A WEEK AFTER PURCHASING MY NEW 2016 GMC SIERRA DENALI 1500 SHORT BED I BEGAN NOTICING A STRONG VIBRATION/SHAKE THAT COULD BE FELT WHILE IN MOTION AT HIGHWAY SPEEDS BETWEEN 75-80MPH. THE FLATTER THE ROAD THE STRONGER THE VIBRATION CAN BE FELT AT THESE SPEEDS. I HAVE BROUGHT IT IN TWICE TO THE DEALERSHIP I BOUGHT IT FROM AND ONCE TO ANOTHER DEALERSHIP YIELDING NO FIX TO THE PROBLEM. ACTUALLY, I HAVE BEEN TOLD THERE IS NO PROBLEM AND THAT IS HOW THE TRUCK RIDES. I HAVE ALSO BEEN TOLD MY EXPECTATIONS FOR A PICKUP TRUCK "UNREALISTIC." WHEN THE FRONT AND PASSENGER SEATS PHYSICALLY SHAKE AT THE SPEEDS MENTIONED I FIND IT VERY HARD TO BELIEVE THAT THERE IS NO ISSUE WITH THE VEHICLE AND THAT MY EXPECTATION SHOULD BE CONSIDERED UNREALISTIC. DRIVING THE TRUCK LONG DISTANCES ON THE HIGHWAY IS UNPLEASANT AT BEST CREATING AT TIMES FEELINGS OF NAUSEA. I HAVE ZERO CONFIDENCE THE ISSUE WILL BE ADDRESSED, BUT WANTED TO AIR MY COMPLAINT FOR OTHER POTENTIAL BUYERS. THIS TRUCK IS SUPPOSED TO BE THE TOP OF THE LINE AND I ABSOLUTELY REGRET BUYING IT WITH THIS PERSISTENT PROBLEM PRESENT THAT NOBODY WANTS TO ADDRESS.

TL* THE CONTACT OWNS A 2016 GMC SIERRA 1500. WHEN THE SHIFTER WAS ENGAGED, THE VEHICLE DID NOT REGISTER THE CORRECT GEAR AND FAILED TO MOVE. WHEN THE VEHICLE DID RECOGNIZE THE CORRECT GEAR, IT ACCELERATED UNINTENTIONALLY. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE TRANSMISSION WAS DEFECTIVE AND PARTS IN THE TRANSMISSION NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED; HOWEVER, THE FAILURE RECURRED. THE VEHICLE WAS RETURNED TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE TRANSMISSION NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 150. UPDATED 10/18/16*LJ *TR

ONE DAY THE POWER STEERING WOULDN'T WORK AT ALL FOR SEVERAL TRIPS. I WOULD TURN THE TRUCK ON AND A SERVICE WARNING MESSAGE WOULD DISPLAY STATING "HAVE YOUR POWER STEERING SERVICED" THE NEXT DAY THE POWER STEERING QUIT WORKING WHILE IN THE MIDDLE OF A TURN. RECEIVED THE SAME WARNING AS I RECEIVED SEVERAL TIMES THE DAY BEFORE.

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

I PURCHASED A NEW GMC SIERRA FROM ROYAL AUTOMOTIVE GMC IN VESTAVIA, AL ON MAY 12, 2016. SINCE THE TIME OF PURCHASE, THERE HAS BEEN A VIBRATION PRESENT, AND NOTICEABLE AT SPEEDS ABOVE 60 MPH. I HAVE TAKEN THE VEHICLE IN TO ROYAL THREE TIMES AND THEY HAVE YET TO REMEDY THIS ISSUE. WHILE OBVIOUSLY ANNOYING, THE ISSUE CAUSES ME HEADACHES, AND I QUESTION WHETHER IT COULD LEAD TO SAFETY ISSUES. I'M CURRENTLY WORKING DIRECTLY WITH GM ON THE ISSUE, BUT THERE IS STILL NO RESOLUTION.

I BOUGHT A NEW 2015 GMC SIERRA 4X4 FROM BOB KING AUTO IN WILMINGTON NC WITH 0 MILE'S ON IT VERY EXPENSIVE TRUCK. YOU CAN'T SEE AT NIGHT TO DRIVE THE HEADLIGHT'S THE HEADLIGHT'S HAVE NO DISTANCE TO THEM MAYBE 25 FT. AND NO SIDE VISION IN OTHER WORD'S YOU CAN'T SEE THE SIDE OF THE ROAD ALSO IF IT'S RAINING AT NIGHT YOU CAN'T SEE ANYTHING TERRIBLE HEADLIGHTS! MY TRUCK WAS LIKE THIS WHEN WE BOUGHT IT NEW IN 2015 AND I HAVE BEEN TRYING SINCE THEN TO RESOLVE THIS ISSUE WITH GENERAL MOTOR'S CORPORATE IN DETROIT MI. THE DEALERSHIP HAS TRIED TO FIX THIS PROBLEM TWICE AND THIS MADE THE PROBLEM WORSE. IN MY OPINION GM SHOULD ISSUE A RECALL ON THESE TRUCKS BEFORE SOMEONE GET'S HURT OR WORSE WHILE TRYING TO SEE WITH THESE DEFECTIVE HEADLIGHTS.

VEHICLE SHAKES & VIBRATES AT SPEED I & OTHER OWNERS ARE REPORTING THAT CONDITION LEADS TO HEADACHES, DIZZINESS, AND NAUSEA. THIS TRUCK IS A REPLACEMENT FOR A 2014 THAT EXHIBITED SAME ISSUES. 2014 WAS TRADED FOR 2016 WITH $$ ASSISTANCE FROM GM WHEN THEY DID ADMIT THERE WAS NO FIX FOR VIBRATION ISSUES. APPARENTLY VIBRATION ISSUES AFFECT 2014, 2015, AND NOW 2016 MODELS. DEALERS ARE FLOODED WITH COMPLAINTS AND VEHICLES IN FOR REPAIR, BUT THERE IS NO REPAIR AVAILABLE. GM IS QUIETLY DOING BUY BACKS OR OFFERING TRADE ASSISTANCE. MY 2016 IS CURRENTLY IN THE SHOP. GM FACTORY REPS HAVE CONFIRMED THAT MY TRUCK DOES SUFFER VIBRATION ISSUES. THIS ISSUE ALSO AFFECTS THE CHEVY SILVERADO, CHEVY TAHOE, AND GMC YUKON. THIS IS WHAT GM BUILT WITH TAX PAYER MONEY! I HAVE DETAILED SERVICE REPORTS FOR 2014 TRUCK AS WELL AS CORRESPONDENCE FROM GM
