2016 GMC SIERRA 1500 Complaints

TL* THE CONTACT OWNS A 2016 A GMC SIERRA 1500. WHILE DRIVING 65 MPH, THE VEHICLE STARTED WOBBLING. THE VEHICLE WAS TAKEN TO WALLINGFORD BUICK GMC (1122 OLD NORTH COLONY RD, WALLINGFORD, CT 06492, (203) 269-8741) WHERE THE BRAKE PADS ON THE FRONT DRIVER'S SIDE WHEEL WERE REPLACED; HOWEVER, THE FAILURE RECURRED. THE VEHICLE WAS TAKEN BACK TO THE DEALER AND TEST DRIVEN. THE TECHNICIAN DIAGNOSED THAT THE ROTORS NEEDED TO BE RESURFACED, THE FRONT BRAKE PADS NEEDED TO BE CHANGED, THE TRANSMISSION FLUID NEEDED TO BE DRAINED, AND THE COMPUTER NEEDED TO BE RESET. THE CONTACT RETRIEVED THE VEHICLE AND THE FAILURES RECURRED THE FOLLOWING DAY. THE DEALER ADVISED THE CONTACT TO GIVE THE VEHICLE A FEW THOUSAND MILES TO WORK OUT THE FAILURES AND STATED THAT THE TRANSMISSION WAS ADJUSTING TO THE CONTACT'S DRIVING HABITS. THE VEHICLE WAS NOT REPAIRED AGAIN AND THE FAILURES WERE STILL PRESENT. THE FAILURE MILEAGE AND VIN WERE UNKNOWN.

AT LOW SPEED THE BRAKES BECOME HARD TO STOP THE VEHICLE AND IN REVERSE THE BRAKE PEDAL BECOME HARD AND BECOMES VERY DIFFICULT TO STOP TRUCK THE TRUCK WAS IN A DRIVE THROUGH AND ALMOST HIT ANOUTHER CAR DUE TO BRAKES FAILING A SERVICE BRAKE BOOSTER SOON WARNING CAME ON

TRUCK LURCHES FORWARD UNEXPECTEDLY DURING SLOW STOPS SUCH AS WHEN APPROACHING A BARRIER TO PARK, A GATE, OR PEDESTRIAN CROSSING. AS THE TRANSMISSION DOWNSHIFTS, THE TORQUE INCREASE CAUSES THE BRAKE PRESSURE BEING APPLIED TO BECOME INSUFFICIENT TO STOP THE VEHICLE CAUSING IT TO LURCH FORWARD UP TO SIX FEET. DURING ACCELLERATION WHILE HIGHWAY DRIVING THE TRANSMISSION MAY UNEXPECTEDLY DOWNSHIFT TO AN INAPPROPRIATE GEAR CAUSING THE ENGINE REV LIMITER TO ENGAGE AND REDUCING POWER UNEXPECTEDLY WHEN IT SHOULD BE INCREASING.

WHEN TRAVELING LOW SPEEDS LIKE IN A PARKING LOT FIRST GEAR JERKS SO BAD IT FEELS LIKE SOMEONE REAR ENDED YOU. GOING HIGHWAY SPEEDS BETWEEN 45 TO 75 YOU FEEL VIBRATIONS COMING FROM THE TRANSMISSION IT FEELS LIKE YOU'RE GOING OVER RUMBLE STRIPS. I HAD MY TRANSMISSION FLUSHED AND CHANGED IT FIX THE VIBRATIONS BUT 3000 MILES LATER THE VIBRATIONS STARTED AGAIN.

I WAS ON MY WAY BACK FROM A BEACH VACATION SATURDAY, JUNE 29, 2019 ALONG WITH TWO OTHER VEHICLES DRIVEN BY OTHER FAMILY MEMBERS. I DRIVE A 2016 SIERRA 1500 SLT WITH 30,000 MILES ON IT. AFTER DRIVING FOR 1 1/2 HOURS WITH MANY OPPORTUNITIES TO USE MY BRAKES, OUR CONVOY NEEDED TO MAKE A STOP TO TURN LEFT. TO MY GREAT SURPRISE THE POWER ASSIST WAS NOT WORKING. AT FIRST I THOUGHT I HAD NO BRAKES AT ALL. I PRESSED HARD WITH BOTH FEET AND STOPPED THE TRUCK BEFORE I REAR ENDED MY SON IN LAW AND HIS FAMILY. SCARED ME TO DEATH!! I PHONED AHEAD TO OUR LEAD CAR AND TOLD THEM I HAD SERIOUS VEHICLE PROBLEMS. THERE'S NO WAY I COULD DRIVE 400 MILES WITH HEAVY TRAFFIC SAFELY. WE SEARCHED FOR THE NEAREST GM DEALER AND SELECTED J. M.JACKSON IN ANDALUSIA, AL. EVEN THOUGH IT WAS A SATURDAY, THE SALES PEOPLE CALLED THE SERVICE MANAGER WHO CAME IN ALONG WITH A SERVICE TECH. SHORTY I HAD A NEW VACUUM PUMP INSTALLED AND THERE WAS NO CHARGE SINCE GM HAD ISSUED A SERVICE BULLETIN. BUT NOW I'M WORRIED ABOUT ANOTHER FAILURE. I BARELY AVOIDED AN ACCIDENT THIS TIME. THERE WAS ABSOLUTELY NO WARNING PRIOR TO FAILURE . AFTER THE INITIAL FAILURE TO BRAKE PROPERLY, I GOT A SERVICE BRAKE ASSIST MESSAGE. VERY DANGEROUS FAILURE. A CRASH WAS NARROWLY AVERTED.

I HAVE HAD ISSUES WITH MY GMC SIERRA SINCE IT WAS NEW. IT HAS JERKED AND CLUNKED WHEN I START TO GO AND THEN LEFT OFF THE GAS. THERE HAS ALSO BEEN A HESITATION WHEN STEPPING ON THE GUESS. I HAVE TAKEN IT TO THE DEALER SEVERAL TIMES AND WAS TOLD THINGS SUCH AS: "I JUST NEEDED TO GET USE TO THE 8 SPEED TRANSMISSION"," THE HESITATION IS WHEN THE TRUCK SWITCHES FROM V4 TO V8". AND "THERE IS NOTHING WRONG". NOW THE WARRANTY HAS EXPIRED AND IT IS GETTING WORSE. IT NOW FEELS LIKE "RUNNING OVER A RUMBLE STRIP" OR LIKE IT IS "MISSING" AND "HESITATING". ALL OF THESE THINGS OCCUR WHEN THE VEHICLE IS IN MOTION.

MY 8 SPEED TRANSMISSION SEEM TO WAIT TOO LONG TO UP SHIFT. WILL DOWN SHIFT AT ODD TIMES. WHEN IS STOP AND GO TRAFFIC AROUND 5-15 MPH THE TRUCK WILL LURCH FORWARD WHEN COASTING OR COMING TO A STOP. WHEN TRUING ON THE TRUCK AND GOING FROM PARK TO REVERSE THERE WILL BE A LOUD "CLUNK" THAT CAN ALSO BE FELT CAUSING THE TRUCK TO ROCK.

WHEN MOVING SLOWLY, THE ABS ERRANTLY ACTUATES RESULTING EXTENDED STOPPING DISTANCE. THIS HAPPENS INTERMITTENTLY. THE LAST TIME I WAS MOVING AT A SLOW (WALKING SPEED) PACE IN A PARKING LOT TO POSITION TO PARK. WHEN I APPLIED THE BRAKES (WHICH SHOULD HAVE STOPPED THE VEHICLE IMMEDIATELY) THE ABS KICKED ON AND, WITH THE BRAKE PEDAL FIRMLY DEPRESSED, THE VEHICLE ROLLED ANOTHER 12FT (APPROX) ALMOST STRIKING ANOTHER CAR WITH SOME PEOPLE STANDING NEARBY. I FEEL THE VEHICLE IS UNSAFE AND CANNOT INSURE AN ACCIDENT WILL EVENTUALLY RESULT.

AIR CONDITIONING FAILED. THIS NEEDS TO BE DOCUMENTED. NOT A "SAFETY" ISSUE AT FIRST, BUT WITH PETS AND KIDS IT CAN BECOME ONE. I HAVE OWNED THIS TRUCK FOR A LITTLE OVER A YEAR. I BOUGHT IT USED FOR OVER $35,000. IT HAD 50,000 MILES ON IT. MY FIRST SUMMER THE A/C WORKED, BUT NOT GREAT. LAST WEEK I TRIED TO USE MY A/C AND NOTHING BUT HOT AIR. I THOUGHT IT WAS STRANGE BEING ONLY A COUPLE YEARS OLD. I PAID TO GET THE FREON RE-CHARGED. THE FREON LEAKED OUT AFTER 2 DAYS AND A/C STOPPED WORKING. I HAD TO SCHEDULE A DIAGNOSTIC APPOINTMENT FOR $118. I HAVE DONE RESEARCH AND IT SOUNDS LIKE I SHOULD BE LOOKING AT A REPAIR COSTING ANYWHERE FROM $800 TO $2,000. THERE HAVE BEEN SEVERAL ONLINE COMPLAINTS, ALONG WITH A CLASS ACTION LAW SUIT TO COVER THIS PROBLEM. THE ISSUE IS THAT IT IS A "LUXURY ITEM" NOT A SAFETY ITEM. IT NEEDS TO BE DOCUMENTED ON ALL WEBSITES THAT THIS IS AN ISSUE, SO CONSUMERS CAN BE INFORMED. THIS CAN BE DANGEROUS WHEN TRAVELING WITH YOUNG CHILDREN AND PETS. THE AIR THAT COMES OUT OF THE VENTS IS EXTREMELY HOT. IN HOT TEMPERATURES THIS CAN BECOME DANGEROUS.

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
