SERVICE BRAKES
LOW SPEED BRAKES HARD AND TAKES TIME TO SLOW AND STOP. BRAKES SEIZED BACKING DOWN DRIVEWAY 2XS. GOT NOTIFICATION FROM GMC THAT THEY ARE AWARE THE VACUUM /POWER MY BE DEFECTIVE AND IF YOU EXPERIENCE THIS PROBLEM THE DEALERSHIP WOULD FIX IT AT NO COST BUT OT HAD TO HAVE LESS THEN 72,00 MILES. DROP IT OFF AT OUR DEALERSHIP AND THEY CLAIM NO PROBLEMS FOUND. THEY HAD FOR 3 DAYS AND JUST DROVE IT AROUND WITH A COMPUTER HOOKED UP TO IT. SAID NO CODES CAME UP SO THEY ARE NOT BOTHERING WITH IT. PICK IT AND STILL THE SAME. HUSBAND WENT BACK. THEY DON'T WANT TO BOTHER CUZ THE MILAGE IS OVER 72,000. WE HAVE 75,000. I AM AFRAID TO DRIVE IT. THEY NEED TO BE RECALLED FOR THE VACUUM /POWER BRAKE ISSUE. OUR TRUCK IS ONLY 4 YRS OLD AND WE PAID BIG MONEY FOR IT. WE LIVE CHEVY/GMC. WE WOULD NEVER OWN ANYTHING ELSE. RECALK IS NEEDED.

GPS INFOTAINMENT SCREEN IS TO BRIGHT AT NIGHT AND THERE IS MINIMAL ADJUSTMENT THAT ALSO DIMS THE INSTRUMENT CLUSTER SO THAT YOU CAN'T SEE IT AND CONTROLS. AFTER DIMMING EVERYTHING TOGETHER INSTRUMENT CLUSTER AND THE GPS SCREEN AND PLACING THE VEHICLE INTO REVERSE THE SCREEN GOES INTO FULL BRIGHTNESS IF YOU PUT IT IN DRIVE THE SCREEN GOES TO THE FRONT CAMERA AND IS DIM LIKE IT WAS BEFORE PLACING IT IN REVERSE. THERE IS NO CONTRAST OR DIM OPTION FOR JUST THE INFOTAINMENT SCREEN. THE ONLY OPTION IS AUOT DAY NIGHT ALL ARE VERY BRIGHT AND DULL GRAY LOOKING LACKING CONTRAST. IT'S VERY DIFFICULT TO DRIVE AT NIGHT WITH THIS SCREEN BLINDING YOU NON STOP THE ONLY THING YOU CAN DO IS PLACE A RAG OVER IT. I CAN'T DRIVE THE TRUCK AT NIGHT IT IS VERY DISTRACTING TO ME AND I DON'T FEEL SAFE.

SERVICE BRAKES, POWER TRAIN
TRUCK HESITATES, JUMPS, AND BUMPS WHEN APPLYING BRAKES. WHEN STEPPING ON BRAKES TO STOP, IT BUMPS AND JUMPS BEFORE IT ACTUALLY COMES TO A FULL STOP. IT SEEMS YOU REALLY HAVE TO STEP ON THE BRAKE HARD TO MAKE IT COME TO A FULL STOP. THIS IS WORSE ON LOW SPEED, BELOW 30 MPH, STOP AND GO TRAFFIC. THERE WERE A NUMBER OF INSTANCES I ALMOST REAR ENDED VEHICLES IN FRONT OF ME DUE TO THIS PROBLEM. THE TRUCK ALSO BUMPS AND JUMPS WHEN TAKING OFF. I THINK THIS STARTED A FEW MONTHS AFTER I GOT THE TRUCK BRAND NEW. IT IS GETTING PROGRESSIVELY WORSE. I TOOK IT A NUMBER OF TIMES TO GM SERVICE CENTER; THEY DID A TRANSMISSION RELEARN, SOFTWARE UPDATES, AND TRANSMISSION FLUSH--TRUCK GOT BETTER FOR ONLY A FEW HUNDRED MILES, THEN SAME PROBLEMS RECURRED. THE LATEST COUPLE OF TIMES I WENT BACK TO GM SERVICE, THEY TOLD ME NOTHING IS WRONG WITH MY TRUCK. IT HAS BEEN VERY FRUSTRATING DEALING WITH THIS PROBLEM AND GM SERVICE FOR THE PAST 3 YEARS.

AFTER COMING TO A STOP OR REACHING SLOW SPEED, THE BRAKE PEDAL BECOMES FIRMER WITH EACH PUMP UNTIL THE PEDAL ONLY MOVES ROUGHLY AN INCH BEFORE STOPPING, AND BRAKING FORCE IS BARELY ENOUGH TO KEEP THE TRUCK FROM IDLING FORWARD. WHEN THIS HAPPENS ON A DOWNWARD SLOPE AT A STOPLIGHT IT REQUIRES MASSIVE AMOUNT OF FORCE ON THE BRAKE PEDAL TO KEEP THE TRUCK FROM ROLLING INTO THE CAR IN FRONT OF IT. ALSO, IF TRAFFIC BEGINS TO MOVE AFTER A STOP AND THEN STOPS AGAIN ABRUPTLY WITHOUT GAINING MUCH SPEED,THE SAME THING WILL OCCUR AND IT IS EXTREMELY DIFFICULT TO NOT HIT THE REAR END OF THE CAR IN FRONT. AFTER DOING SOME RESEARCH THIS SEEMS TO BE A COMMON ISSUE WITH THE VACUUM PUMP. I WILL BE VISITING A DEALER SOON. 2015 GMC SIERRA SLT WITH 57,000 MILES.

WHILE DRIVING APPROXIMATELY 55-60 MPH, THE INSTRUMENT PANEL INDICATORS FLICKERED ON AND OFF, THE TACHOMETER AND OTHER GAUGES BECAME INOPERABLE, AND THE VEHICLE LOST POWER. ADDITIONALLY, THE ACCELERATOR PEDAL WAS DEPRESSED; HOWEVER, THE VEHICLE FAILED TO RESPOND. THE CONTACT PULLED OFF OF THE ROADWAY AND SHUT OFF THE VEHICLE.

WHEN THE POSITIVE TERMINAL WIRE WAS REMOVED FROM THE BATTERY AND REPLACED, THE VEHICLE STARTED AND OPERATED NORMALLY. THE VEHICLE WAS NOT DIAGNOSED OOR REPAIRED. THE CONTACT STATED THAT THE FAILURE WAS INTERMITTENT. THE MANUFACTURER AND DEALER WERE NOT INFORMED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 110,000.

SERVICE BRAKES, POWER TRAIN
BRAKE FAILURE ISSUE AT LOW SPEED. THIS HAPPENED IN TWO SEPARATE OCCURRENCES IN PARKING LOTS. THE BRAKE PEDAL BECAME VERY STILL AND REQUIRED GRABBING THE STEERING WHEEL AND USING IT TO PULL MYSELF DOWN HARDER ON THE BRAKE PEDAL TO GET THE VEHICLE TO STOP. THIS RESULTED IN GREATLY INCREASED STOPPING DISTANCE. FORTUNATELY NO VEHICLES OR PEOPLE WERE IN MY PATH DURING THESE OCCURRENCES. GM HAS SINCE REPAIRED MY VEHICLE. I HAVE SINCE RECEIVED A NOTICE THAT THEY ARE REPAIRING THIS ISSUE ONLY AFTER THE OWNER HAS A BRAKE FAILURE PROBLEM. THIS IS EXTREMELY UNSAFE AND IS UNACCEPTABLE. OWNERS NEED A SOLUTION AND DO NOT NEED TO WORRY THAT THIS ISSUE WILL ARISE AGAIN. IF I HIT A PERSON OR A VEHICLE, WILL GM PAY FOR MEDICAL BILLS, VEHICLE REPAIRS, LEGAL FEES? THIS TRUCK AS WELL AS MY LAST 2009 CHEVROLET SILVERADO HAD ISSUES WITH THE DRIVE TRAIN THAT GM CLASSIFIED AS NORMAL. THESE TRUCKS SHOULD NOT HAVE DRIVE SHAFT CLUNK WHEN STOPPING AT A TRAFFIC LIGHT. THESE VEHICLES HAVE MAJOR MECHANICAL CONCERNS AND THEIR QUALITY IS TRASH!

THIS ISSUE BEGAN LAST YEAR IN NOV. 2018. WE WERE IN TRAFFIC AND STOPPING AND GOING UNTIL WE COULDN'T STOP AND THE BRAKE PEDAL WAS TO THE FLOOR AND THE CAR WAS STILL MOVING. WE BROUGHT THE TRUCK TO THE DEALER AND THEY SAID IT WAS THE BRAKE PADS. WE PAYED $1700 TO REPLACE ALL THE PADS. THE OTHER DAY (3 MONTHS WITH THE NEW BRAKES) THE ISSUE HAPPENED AGAIN AND THE TRUCK WOULDN'T STOP, ALMOST CAUSING AN ACCIDENT THAT COULD HAVE SERIOUSLY INJURED THE ELDERLY LADY IN FRONT OF US AND OURSELVES. THIS ISSUE IS GETTING WORSE AND PRESENTS A HAZARD TO US AND EVERYONE ON THE ROAD. THIS ISSUE OCCURS AT RANDOM TIMES, SLOWING TO GET OFF AN EXIT RAMP, IN TRAFFIC, STOPPING FOR CROSS WALKERS, ETC. WE BROUGHT IT TO THE DEALERSHIP AND THEY REQUIRE US TO REENACT (PUTTING EVERYONE IN DANGER) THE ISSUE AND UNTIL THEY EXPERIENCE IT, THEY WON'T FIX IT. LEAVING US WITH A CAR THAT DOESN'T STOP THAT WILL SOONER OR LATER CAUSE AN ACCIDENT.

THE DOOR LOCKS DONT ALWAYS LOCK. MY GRANDSON WAS IN THE BACK SEAT AND FELL ASLEEP, WHILE ASLEEP HE BUMPED THE DOOR HANDLE AND THE DOOR OPENED WHILE WE WERE GOING 50 MPH., LUCKY HE HAD THE SEAT BELT ON. THE DOOR SHOULD NOT HAVE OPENED AS THE LOCK SHOULD HAVE ENGAGED WHEN THE TRUCK IS PUT IN GEAR AND MADE THE DOOR HANDLE INOPERABLE. THE DOOR LOCK ACTUATOR IS THE PROBLEM, THIS WILL BE THE SECOND ONE REPLACED. YOU DONT KNOW THEY DONT WORK BECAUSE THEY MAKE A LOCKING SOUND WHEN ACTIVATED. THEY JUST DONT LOCK, VERY DANGEROUS GLAD HE DIDNT FALL OUT OF THE VEHICLE.

DAILY THE TRANSMISSION HAS A HARD SHIFT FROM 1ST TO 2ND GEAR. POTENTIALLY CAUSING ME TO LOOSE CONTROL OF THE VEHICLE. IVE HAD IT IN THE GMC SHOP 3 TIMES AND GMC IS UNABLE TO FIX THE PROBLEM. AFTER THE VEHICLE SITS FOR PERIODS OF 4 HRS OR MORE THE PROBLEM REOCCURS. THIS IS A SERIOUS POLITICAL SAFTEY HAZARD IN THE 8SPEED TRANSMISSION AND NEEDS TO BE RECALLED AND FIXED WITH A NEW TRANSMISSION.
