AFTER PARKING AND BACKING UP WHEN I HIT THE BRAKES, THEY GOT HARD AND DID NOT OPERATE PROPERLY. WHEN PULLING FORWARD THE BRAKES WERE HARD TO OPERATE AND BARELY STOPPED THE VEHICLE. AFTER SITTING A WHILE AND RESTARTING THE TRUCK THEY OPERATED AS THEY SHOULD HAVE. NOT SURE IF THIS IS AN OPERABLE SAFETY ISSUE BUT, IT WAS VERY CONCERNING THAT THE BRAKES DID NOT OPERATE PROPERLY.

COOLANT LIGHT CONTINUES TO COME ON. I'VE HAD IT TO THE SHOP AND THEY SAY THAT IT IS A MANUFACTURING PROBLEM. HOWEVER THEY ARE NOT WILLING TO FIX IT. I HAVE THE SAME PROBLEM ON MY CHEVY HIGH COUNTRY THAT HAS THE SAME 6.6 DIESEL ENGINE IN IT. THE MECHANICS ALL ACKNOWLEDGE THAT THIS IS A PROBLEM FOR ALL OF THESE MODEL 6.6 DIESEL REGARDLESS OF WHETHER IT IS GMC OR CHEVY. THIS SHOULD DEFINITELY BE A RECALL. THE WARNING LIGHT CONTINUALLY COMES UP ON THE DISPLAY SAYING I AM LOW ON FLUID. HOWEVER, WHEN I CHECK IT IT IS ALWAYS FULL. THERE IS A HIGH CHANCE THAT IF IT IS LOW I WILL AUTOMATICALLY RESET IT THINKING THAT THE WARNING LIGHT IS NOT FUNCTIONING CORRECTLY. AGAIN, THE GM TEXT KNOWS THAT THIS IS A PROBLEM THROUGHOUT THE FLEET. AGAIN, THIS SHOULD BE A RECALL. IF YOU HAVE FURTHER QUESTIONS YOU CAN REACH ME AT [XXX] THANK YOU FOR YOUR TIME, [XXX].

I LIVE IN OREGON, MY TRUCK THAT I PURCHASED FROM A PRIVATE OWNER FROM UTAH IN JUNE OF 2019 HAD 37,300 MILES TODAY'S DATE MARCH 1 2020 MY TRUCK HAS 39,100 MILES. A COUPLE OF DAYS AGO I CHANGED TO MY OREGON LICENSE PLATE. WHILE UNDER THE TRUCK I NOTICED A LOT OF RUST ON MANY PARTS OF THE BRAKES, SUSPENSION AND FRAME ESPECIALLY WHEN I LOWERED THE SPARE TIRE WHICH SHOWED SEVERE RUST DAMAGE. THIS TRUCK HAS AN EXTREME AMOUNT OF RUST FOR A VEHICLE BUILT IN 2017. I CONSIDER THIS TO BE A SAFETY HAZARD ESPECIALLY BECAUSE DRIVERS USE THIS TYPE OF TRUCK TO HAUL OR TOW HEAVY LOADS.

TRUCK WAS RECALLED FOR BRAKES. RECALL COMPLETED WAS COMPUTER ISSUE. THAT RECALL CAUSED BRAKE VACUUM TO MALFUNCTION. ALMOST COST ME MY LIFE. 70 MPH IN DALLAS TX TRAFFIC. HAD TO SLOW DOWN QUICKLY. ONCE IT SLOWED DOWN THEN IT WOULDN'T STOP!!! GOT IT TO A PARKING GARAGE ALMOST HIT 3 VEHS. IT WAS TRAUMATIC. GM KNOWS ABOUT THIS ISSUE. MANY OTHERS HAVE REPORTED. NOT HAPPY!!!!! GM EXTENDED THE BRAKE WARRANTY TO 150000 MILES. THAT MAKES ME FEEL BETTER. THEY PUT SAME PART BACK ON. SO I GUESS IT WILL HAPPEN AGAIN. I'M VERY LEARY OF MY TRUCK.

MY 2017 GMC SIERRA DENALI HAD ALREADY BEEN THE SUBJECT OF THE RECALL RELATING TO THE BRAKE ISSUE. SHORTLY AFTER THEY PERFORMED THIS RECALL WORK THE BRAKES BEGAN FAILING AT LOW SPEED. WHEN DRIVING BELOW 5 MPH, THE PEDAL WHICH SUDDENLY FALL AND THE ABS WOULD TRIGGER. DURING THIS TIME, THE CAR WOULD CONTINUE MOVING WITH THE ABS FULLY VIBRATING. THANKFULLY, MY TRAILER HITCH ABSORB THE REAR IMPACT AGAINST A WALL. THE PROBLEM CONTINUED. I THEN TOOK THE TRUCK IN FOR SERVICE AND THEY REPORTED THAT THERE HAS BEEN A SIGNIFICANT FAILURE RATE OF THE VACUUM ASSIST. THE DEALER REPLACE THE VACUUM PUMP AND VACUUM LINES. I'M EXTREMELY CONCERNED THAT THIS WOULD HAPPEN TO SOMEONE ELSE NEAR AN INTERSECTION, NOT JUST SLOWLY BACKING INTO PARKING SPACES. I HAVE CONTACTED GMC BY EMAIL BUT STILL HAVE RECEIVED NO RESPONSE OR ACKNOWLEDGMENT OF MY COMMUNICATIONS.

REFERENCE THE COMPLAINT NUMBER 11306627. THE VEHICLE HAD THE BRAKE RECALL NOTICE N192268490 COMPLIED WITH AT THE DEALER IN NOVEMBER 2019. THE VEHICLE THEN EXPERIENCED A BRAKE FAILURE IN FEBRUARY 2020. PLEASE ADD THIS INFORMATION TO MY ORIGINAL COMPLAINT.

IN MY DRIVEWAY ON DRY PAVEMENT AT SLOW SPEEDS WHEN PRESSING THE BRAKE PEDAL THE VEHICLE DOES NOT STOP SATISFACTORY. THE BRAKE PEDAL WAS THEN PRESSED UNTIL IT WAS VERY HARD THE VEHICLE CONTINUED TO MOVE BUT SLOWLY BEGAN TO STOP. WHEN PRESSING THE BRAKE PEDAL TO THE MAXIMUM AND A FIRM PEDAL A NOISE COULD BE HEARD FROM UNDER THE HOOD. THE NOISE SOUNDED LIKE A MOAN, SIMILAR TO THE BRAKE ANTI SKID SYSTEM BEING ACTIVATED. I WAS ABLE TO SIMULATE THIS BRAKING PROBLEM MULTIPLE TIMES WHILE BACKING UP AND MOVING FORWARD AT SLOW SPEEDS. CYCLING THE IGNITION ON AND OFF DID NOT CORRECT THE PROBLEM.

BRAKE VACUUM PUMP FAILURE. VEHICLE BRAKE PEDAL BECOMES VERY HARD TO DEPRESS AT SLOW SPEED AND VERY HARD TO STOP. USUALLY HAPPENS WHEN IN SLOW TRAFFIC AND AFTER THE PEDAL IS DEPRESS MORE THAN 2-3 TIMES IN A ROW.

MY BRAKES ARE NOT WORKING TO ITS FULL POTENTIAL. I BELIEVE MY VACUUM PUMP IS GOING BACK ON MY TRUCK. I NOTICED LAST WEEK THAT I WAS DRIVING OUT OF A PARKING LOT AND COMING TO A STOP SIGN AND I PRESSED MY BRAKES AND IT WAS NOT WORKING PROPERLY. I HAD TO RELEASE THE BRAKE AND SLAM ON THE BRAKES AGAIN ALMOST CAUSING A ACCIDENT WITH INCOMING TRAFFIC. I CALLED ALL MY LOCAL DEALERSHIPS AND STATED THAT THERE WAS NO RECALL ON THIS JUST YET FOR MY TRUCK, BUT THERE IS A RECALL ON THE VACUUM PUMP. THEY STATED THEY ALREADY DID THE SOFTWARE UPDATE TO MY TRUCK BACK IN SEPTEMBER 2019. MY TRUCK WAS GOING MAYBE 10 MPH TO A STOP SIGN AND I APPLIED MY BRAKES ONCE AND WAS NOT COMPLETELY STOPPING, SO I TOOK MY FOOT OFF THE BRAKE PEDAL, AND IT GOT WORSE AND I HAD THE BRAKES PRESSED ALL THE WAY DOWN TO THE FLOOR. THIS IS NOT SAFE! THIS IS MY DAILY DRIVER AND I DROP MY KIDS OFF TO SCHOOL EVERY DAY AND ITS NOT A GOOD FEELING KNOWING MY BRAKES CAN GO OUT AT ANY TIME!

NOTICED MUSHY, VIBRATING BRAKES. TOOK IT TO TIRE STORE AND WAS ADVISED THE BRAKE BOOSTER AND VACUUM PUMP ARE BAD. I'VE HAD SEVERAL CLOSE CALLS IN PARKING LOTS, AS THE VEHICLE IS SLOW TO RESOND TO THE APPLICATION OF THE BRAKES. THE DRIVERS SEAT IS ALSO LOOSE. IT MOVES FROM SIDE TO SIDE AS I GO AROUND CORNERS. I'M AFRAID IT WILL COME OFF THE RAILS OR WORSE YET, NOT SECURE ME IN THE EVENT OF AN ACCIDENT.

WHEN I'M DRIVING AT A SLOW SPEED TURNING THE TRUCK LOOSES ALL POWER AND THE STEERING WHEEL JERKS OUT OF MY HAND, STABILITRAK IS ON THE DISPLAY AND IT SAYS ROLL DOWN DRIVER WINDOW AND ROLL BACK UP! IT ALSO LOOSES ALL POWER JUST DRIVING DOWN THE ROAD NO MATTER THE SPEED! I HAVE ALSO BEEN STOPPED AT A STOPLIGHT AND IT LOST ALL POWER WOULDN'T COME BACK ON SO I HAD TO GET OUT POP THE HOOD AND BANG I. THE BATTERY BOX AND CABLES AND IT STARTED AGAIN! VERY SCARY GOING 75 MPH AND IT SHUTS OFF LEAVING YOU NO STEERING NO BRAKES NO LIGHTS NO NOTHING! SOMETIMES IT SAYS POWER STEERING FAILURE SOMETIMES AND SOMETIMES IT SAYS STABILITRACK PROBLEM AT SOMETHING ABOUT TOWING! THE BRAKES WERE ALSO AFFECTED NO BRAKES

TL* THE CONTACT OWNS A 2017 GMC SIERRA. THE CONTACT STATED THAT WHILE DRIVING AT 70 MPH THEIR WAS SUDDEN LOSS OF MOTIVE POWER AND THE GEARS DISENGAGED. THE CONTACT STATED THE CHECK ENGINE WARNING LIGHT ILLUMINATED. THE CONTACT PULLED THE VEHICLE TO THE SIDE OF THE ROAD AND RESTARTED VEHICLE AND THE CHECK ENGINE WARNING LIGHT DISAPPEARED. THE VEHICLE WAS TOWED TO (DUBLIN CHEVROLET GMC BUICK, 2042 VETERANS BLVD, DUBLIN, GA 31021 (478-246-4916) WHERE IT WAS DIAGNOSED THAT THE TRANSMISSION SHOWED EVIDENCE OF LARGE AMOUNTS OF METAL SHAVINGS FROM THE TORQUE CONVERTER. THE OIL PAN ALSO SHOWED EVIDENCE BURNT METAL. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND A CASE WAS OPENED. THE FAILURE MILEAGE WAS 61,719.

THERE IS A SHUTTERING IN THE TRANSMISSION AS THE VEHICLE ATTEMPTS TO CLIMB SLIGHT/STEEP GRADES AT SLOW TO MEDIUM SPEEDS. AROUND 1500 RPM THE VIBRATION IS SENT THROUGHOUT THE WHOLE VEHICLE. HAVING TO INCREASE ACCELERATION TO ALLOW THE TRUCK TO SHIFT PROPERLY TO OVERCOME THE LACK OF POWER HAS CREATED A DANGEROUS SITUATION WHILE NAVIGATING UP SNOWY/ICE HILLS. THE VEHICLE ALSO PERFORMS A LURCHING OR SUDDEN SPEEDING UP WHEN DOWNSHIFTING WHEN SLOWING TO COME TO A STOP. DEPENDING ON ROAD CONDITIONS THIS CREATES A DANGEROUS SITUATION WHEN APPROACHING ICY/SLIPPERY INTERSECTIONS.

VEHICLE FREQUENTLY EXHIBITS LOSS OF BRAKING POWER. WHEN THIS OCCURS, SOMETHING SOUNDING LIKE THE ABS SYSTEMS IS SOMETIMES ENGAGED BY THE VEHICLE AND OTHER TIMES NOT. WHILE GM CLAIMS BRAKING PERFORMANCE MEETS FEDERAL STANDARDS, THE BRAKING POWER IS GREATLY REDUCED WHEN THE HYDRAULIC SYSTEM IS ENGAGED AND ALMOST NON-EXISTENT WHEN NEITHER VACUUM PUMP NOR THE HYDRAULIC SYSTEM FUNCTIONS. EVEN IF THE BRAKING PERFORMANCE MEETS FEDERAL STANDARDS, IT CREATES A DANGEROUS SITUATION WHEN THE DRIVER IS NOT EXPECTING A FAILURE. A GMC DEALERSHIP HAS ADMITTED THERE IS AN ISSUE AND RECOMMENDS REPLACING THE VACUUM PUMP BUT HAS BEEN UNABLE TO SOURCE THE PARTS IN OVER TWO WEEKS AND HAS NO ETA FOR WHEN THE PART WILL BE AVAILABLE. MEANWHILE THE BRAKING POWER LOSS CONDITION OCCURS EVERY TIME THE VEHICLE IS DRIVEN. DURING THE FIRST INSTANCE, I WAS TOWING A TRAVEL TRAILER IN STOP AND GO TRAFFIC DOWN A 7% GRADE. HAD IT NOT BEEN FOR THE TRAILER BRAKES, THIS COULD HAVE BEEN CATASTROPHIC. THE SECOND OCCURRENCE INVOLVED BACKING INTO MY DRIVEWAY AND NEARLY CAUSING A COLLISION BECAUSE OF POOR BRAKING PERFORMANCE. NOW THAT I FULLY AWARE OF THE ISSUE, THE VEHICLE IS DRIVEN SPARINGLY (ONLY WHEN ABSOLUTELY NEEDED) AND WITH GREAT CARE. THE CHARACTERIZATION OF THIS ISSUE BY GM AS NOT BEING A GRAVE SAFETY CONCERN IS INACCURATE. THEIR INABILITY TO SOURCE PARTS IN A TIMELY MANNER IS INEXCUSABLE.

WHILE OPERATING VEHICLE ON HIGHWAY, I EXPERIENCE A SHAKE/SHUDDER WHEN AT SPEEDS OF 50 MPH AND HIGHER. VEHICLE WAS TAKEN TO DEALER STATED THAT THE TORQUE CONVERTER DID SHUDDER. DEALER CHANGED TRANSMISSION FLUID AND I WAS ADVISED TO DRIVE FOR 200 MILES TO SEE IF PROBLEM WAS CORRECTED. SHUDDER STILL REMAINS AND NOW THE VIBRATION IS CONSTANT AT 70 MPH. I CALLED DEALER AGAIN WHO SAID THAT IT WAS PROBABLY A TIRE BALANCE ISSUE. I ARGUED WITH THEM AND STATED I HAD NO SUCH ISSUE BEFORE FIRST BRINGING VEHICLE IN. DEALER IS SETTING UP APPOINTMENT FOR ME TO TAKE IN AGAIN. VIBRATIONS HAVE LITERALLY CAUSED MY 6 YR OLD DAUGHTER TO VOMIT ON 3 DIFFERENT OCCASIONS WHEN IN THE VEHICLE. SHE HAS ONLY BEEN IN VEHICLE 5 OR 6 TIMES. VEHICLE FEELS UNSAFE AT HIGHWAY SPEEDS. I HAVE READ MANY FORUMS ONLINE STATING THIS ISSUE IS ON MANY VEHICLES GM HAS MADE. I AM CURIOUS AS TO WHEN GM WILL BE MANDATED TO TAKE CORRECTIVE ACTION OR BUY THE VEHICLES BACK FROM THE OWNERS.

FIRST AND MOST IMPORTANTLY MY BRAKES ARE MY MAIN ISSUE AND SAFETY PROBLEM. I NEARLY RAN INTO THE CAR IN FRONT OF ME AT A BUSY INTERSECTION. MY TRUCKS BRAKES LOSE PRESSURE AFTER THE FIRST INITIAL STOP COMING TO ANY TRAFFIC LIGHTS, STOP SIGN, SLOW TRAFFIC, PARKING LOTS ETC... NO MATTER HOW SLOW OR FAST THE TRUCKS MOVEMENT IS. FIRST BREAK ATTEMPT IS OK BUT 2ND STARTS LOSING PRESSURE AND 3RD ATTEMPT IS COMPLETE LOST OF PRESSURE ANF AND THE TRUCK JUST ROLLS UNTIL IT SLOWLY COMES TO A STOP. I WORRY ABOUT THE SAFETY OF MYSELF AND OTHERS MOTORIST REGARDING THIS ISSUE. MY SECOND COMPLAINT IS MY DRIVER SIDE MIRROR. EVERY TIME I GET INTO MY TRUCK AND START IT. MY DRIVER SIDE MIRROR MOVES OUT OF ITS SETTING AND I CONSTANTLY HAVE TO FIX IT.

THE PAST MONTH AS I PUSH ON THE BRAKES DRIVING ON THE ROAD MY STEERING WHEEL STARTS TO SHAKE AS THE BRAKES ARE BEING APPLIED. DOES NOT HAPPEN ALL THE TIME HAS ACTUALLY ONLY HAPPENED 3 TIMES IN A MONTH.

AFTER USING THE REMOTE STARTER WHILE VEHICLE WAS PARKED IN MY DRIVEWAY, I STARTED TO DRIVE MY GRANDSON TO SCHOOL. A SHORT DISTANCE FROM HOME SMOKE AND SPARKS STARTED TO EMIT FROM THE REAR SEAT NEXT TO THE SLIDING WINDOW AND ELECTRIC REAR WINDOW DEFROSTER. AS I PULLED OVER THE REAR WINDOW PANEL ON THE PASSENGER SIDE BURST. I ASSUME FROM EXCESSIVE HEAT GENERATED BY THE REAR WINDOW DEFROSTER.

WHILE BRAKING PEDAL FEELS LIKE GURGLING AND AT TIMES COMPLETE LOSS OF POWER ASSIST MAKING PEDAL VERY HARD TO DEPRESS ALL WERE IN MOTION AND INTERMITTENT MAKING DEALER DIAGNOSIS DIFFICULT AND NOT YET ABLE TO REPLICATE SO DEALER REFUSES TO DO WORK

OCTOBER 2019 WENT TO THE DEALERSHIP TO HAVE BREAKS WORKED ON GIVEN RECENT RECALL ABOUT THE MECHANICAL VACUUM PUMP OUTPUT MAY DECREASE OVER TIME, DECREASING THE AMOUNT OF VACUUM/POWER BRAKE ASSIST. HOWEVER, SHORTLY AFTER GETTING THE RECALL DONE ON MY TRUCK (1 WEEK LATER) I WAS IN THE PARKING LOT BACKING UP OUT OF MY PARKING SPOT AND THE BREAK PEDAL BECAME REALLY STIFF AND I COULDN'T PUSH HARD ENOUGH TO STOP THE VEHICLE FROM MOVING. I JUST KEPT ROLLING UNTIL I HIT THE CURB. SO FAR THIS HAS HAPPENED A DOZEN TIMES AND ALL WHEN I WAS MOVING ABOUT 5 MILES AN HOUR THE EXACT SAME WAY, PEDAL BECOMES STIFF AND I COULDN'T STOP THE TRUCK FROM MOVING. I FEEL LIKE THINGS ARE WORSE NOW AFTER GETTING THE RECALL DONE. THIS WAS NEVER AN ISSUE BEFORE AND AS I LOOK AT THE RECALL NOTICE, IT STATE INCOMPLETE, TELLING ME POSSIBLY THE MANUFACTURE KNOWS THERE'S STILL AN ISSUE BUT NO FIX HAS BEEN DONE YET, EVEN AFTER 4 MONTHS.

FOR NHTSA RECALL 19V645, WHY DID NHTSA ACCEPT A 'REPROGRAMMING' OF THE FUNCTIONALITY TO 'BAND AID' THE ISSUE RATHER THAN REQUIRING REPLACEMENT OF THE VACUUM PUMP, WHICH IS THE IDENTIFIED DEFECTIVE ITEM?

WE WERE DRIVING UP A SLIGHT INCLINE IN A PARKING GARAGE WHEN THE ENGINE STARTED SPUTTERING AND SHUT OFF. AFTER SEVERAL ATTEMPTS IT STARTED AND WE WERE ABLE TO MAKE IT TO A PARKING SPACE WITH THE ENGINE STILL SPUTTERING. I RECEIVED A NOTIFICATION FROM THE TRUCK, DECREASED ENGINE POWER. THE NEXT DAY I BROUGHT IT TO BE CHECKED BY THE LOCAL GMC DEALER. THEIR DIAGNOSIS IS VAPOR LOCK WHEN THE FUEL PUMP GETS NEAR OR OVER 100 DEGREE. ITS MY OPINION THAT GMC PLACED A FAULTY PART WHEN MANUFACTURING THE VEHICLE. I WOULD LIKE THIS TO BE CONSIDERED FOR RECALL.

GMC HAS REFUSED TO FIND A FIX FOR THE HEATER CORD DEFECT WHICH IS ONE OF THE MAIN REASON WHY I PURCHASED THE VEHICLE. I LIVE IN IDAHO. GMC SHOULD COMPENSATE OWNERS UNTIL FIXED.

SINCE DECEMBER OF 2017 THE TRANSMISSION, WHEN COLD, AT APPROX. 25 MPH AND AT 40-44 MPH WHEN NEUTRAL THROTTLE IS APPLIED, BANGS BETWEEN GEARS FORCING THE OPERATOR TO EITHER ACCELERATE OR DECELERATE SO THE CONDITION WILL CEASE. IF THERE IS NO CHANGE BY THE OPERATOR, IT FEELS AS IF THE TRANSMISSION WILL BREAK THE U-JOINTS IN THE DRIVELINE OR BLOWOUT THE REAR-END GEARS. I HAVE MADE NUMEROUS ATTEMPTS WITH GMC TO REMEDY THE ISSUE TO NO AVAIL. THE VEHICLE HAS BEEN IN THE DEALERSHIP IN EXCESS OF 40 DAYS FOR THE SAME PROBLEM WITH NO RESOLUTION

ONLY HAVE 18,820 MILES ON OUR TRUCK AND THE AIRBAG LIGHT IS ON. SHOULDN'T HAVE ISSUES WITH AIRBAGS ON A TRUCK THAT'S BARELY DRIVEN.

VEHICLE SHIFTS VERY HARD IN AND OUT OF 1ST AND 2ND GEAR. WHEN STARTING TO GO AT LOW SPEEDS THE VEHICLE ALMOST STOPS WHEN SHIFTING AND THEN JERKS WHEN IT SHIFTS. SAME OCCURS WHEN SLOWING TO A STOP. VEHICLE WAS TAKEN TO THE DEALER AND THE POWER TRAIN WAS REPROGRAMMED. THE ISSUE WAS A LITTLE BETTER FOR A WHILE. A FEW WEEKS LATER THE SAME ISSUE APPEARED AGAIN. VEHICLE WAS TAKEN BACK TO THE DEALER IN JANUARY 2020 AND THERE IS NOW A CHECK ENGINE CODE. DEALER PLANS TO CHANGE 2 HARNESSES AND CHANGE THE FLUID. UNFORTUNATELY THE PARTS ARE ON BACK ORDER WHICH KIND OF TELLS A STORY.

AS I WAS BACKING UP I APPLIED MY BRAKES AND FOR SOME REASON NOTHING HAPPENED WHICH RESULTED IN MY HITTING MY WIFE'S CAR AND DAMAGING HER DRIVERS SIDE QUARTER PANEL. WHEN I ASKED GMC ABOUT THE ISSUE THEY SAID IT WAS JUST AN ERROR ON MY PART. NOW I FIND OUT THAT THERE IS A RECALL ON THE BRAKING SYSTEM THAT THE PRESSURE TO THE BRAKES MAY BE AFFECTED. WHO IS RESPONSIBLE FOR THE DAMAGE TO HER CAR?

HARD SHIFTING BETWEEN GEARS AND COMING TO A STOP

TL* THE CONTACT OWNS A 2017 GMC SIERRA EQUIPPED WITH CONTINENTAL CROSSCONTACT LX TIRES, SIZE: 275/552/0352 (NA). THE CONTACT STATED THAT THE TIRES FLATTENED. THE TIRES WERE THE ORIGINAL TIRES AND THEY LOST AIR IMMEDIATELY. DIAMOND AUTO GROUP (768 WASHINGTON ST RT. 20, AUBURN, MA 01501, (508) 635-4207) WAS CONTACTED, BUT THEY DID NOT WANT TO REPAIR OR CHANGE THE TIRES. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND DID NOT ASSIST. THE VEHICLE FAILURE MILEAGE WAS 33,731 AND THE TIRE FAILURE MILEAGE WAS 73,000. THE VIN WAS UNKNOWN.

TL* THE CONTACT OWNS A 2017 GMC SIERRA. THE CONTACT RECEIVED NOTIFICATION OF NHTSA CAMPAIGN NUMBER 19V328000 (ENGINE) HOWEVER, THE PART FOR THE RECALL REPAIR WAS UNAVAILABLE. THE CONTACT STATED THAT THE MANUFACTURER HAD EXCEEDED A REASONABLE AMOUNT OF TIME FOR THE RECALL REPAIR. THE CONTACT HAD NOT EXPERIENCED ANY FAILURE. THE CONTACT CONTACTED THE DEALER (WHEELER CHEVROLET BUICK LOCATED AT 11401 N STRAITS HWY, CHEBOYGAN, MI 49721) WHO INFORMED THE CONTACT THAT THE PART FOR THE REPAIR WAS UNAVAILABLE.

THE CONTACT RECEIVED THE RECALL NOTICE IN FEBRUARY OF 2019. SPRINGFIELD BUICK GMC (431 RIVER ST, NORTH SPRINGFIELD, VT 05150) STATED THAT THE PARTS WERE UNAVAILABLE TO PERFORM THE REPAIR. THE MANUFACTURER WAS ALSO CONTACTED AND CONFIRMED THAT THE PARTS WERE UNAVAILABLE. THE CONTACT HAD NOT EXPERIENCED A FAILURE. VIN TOOL CONFIRMS PARTS NOT AVAILABLE.

TRUCK LAGS POWER WHEN PRESSING THE GAS PEDAL AT TIMES AFTER PUTTING TRANSMISSION INTO DRIVE FROM REVERSE. TRANSMISSION SHIFTS HARD INTO AND OUT OF FIRST GEAR AND AT TIMES FEELS LIKE IT IS SKIPPING 2ND GEAR DURING A DOWNSHIFT.

WAS DRIVING MY 2017 GMC SIERRA WITH MY WIFE AND YOUNG SON. I WENT TO STOP AT A RED LIGHT AND HAD NO BRAKES. THE BRAKE WAS VERY HARD TO PUSH AND MADE A FUNNY CLICKING NOISE WHEN I SHOVED IT TO THE FLOOR. I WAS BARELY ABLE TO AVOID A COLLISION AND PULL INTO A PARKING LOT. I NOTICED THEN, THAT THE SERVICE BRAKE ASSIST LIGHT WAS ON. THE TRUCK GAVE NO PRIOR WARNING THAT ANYTHING WAS WRONG. THIS WAS A VERY SCARY SITUATION THAT COULD HAVE RESULTED IN A TERRIBLE ACCIDENT.

VEHICLE IS SHUDDERING AND SHACKING AT SPEEDS ANY WHERE FROM 35 TO 55 MPH. I TOOK IT TO THE DEALERSHIP AND WAS TOLD IT'S A KNOWN TORQUE CONVERTER ISSUE.

WHEN REVERSE IS ACTIVATED AT NIGHT, THE BACKUP CAMERA COMES ON AT FULL BRIGHTNESS AND IS NOT DIMMABLE. THE BRIGHT SCREEN PREVENTS VIEW OF THE PASSENGER SIDE MIRROR AND SIGNIFICANTLY REDUCES VISIBILITY IN THE DRIVER SIDE MIRROR WHILE REVERSING. THE SCREEN CANNOT BE DEACTIVATED AND BLINDS THE DRIVER. THIS IS AN ONGOING ISSUE.

WHILE DRIVING ON THE HIGHWAY AT 70MPH, A SERVICE BRAKE ASSISTANT WARNING CAME ON. THE BRAKES AT THAT POINT WERE EXTREMELY DIFFICULT TO USE AND THERE WAS NO WAY FOR A QUICK STOP. WAS ABLE TO GET TO A DEALERSHIP WHERE THEY HAD TO REPLACE THE MASTER CYLINDER, THE BOOSTER PUMP, VACUUM PUMP AND TUBING. COST FOR THE REPAIR WAS OVER $1,200.

THE VEHICLE EXHIBITS VIBRATIONS THAT CAN BE RATHER EXTREME AT TIMES. IT SEEMS TO BE MOST NOTICEABLE IN THE 70-75 MPH RANGE BUT CAN SOMETIMES BE FELT AT OTHER SPEEDS. IT FEELS LIKE THE VIBRATION ORIGINATES FROM THE REAR OF THE VEHICLE. TWO DEALERSHIPS HAVE REPLACED MULTIPLE PARTS AND HAVE PERFORMED NUMEROUS ALIGNMENTS AND ROAD FORCE BALANCES BUT CAN NOT IDENTIFY/REMEDY THE PROBLEM. THERE ARE THOUSANDS OF COMPLAINTS ON MULTIPLE ONLINE FORUMS OF THIS SAME ISSUE FOR 2014-2015 GM 1500 SERIES PICKUP TRUCK. SO FAR THERE HAS BEEN NO FIX FOR THEM EITHER. GM TREATS IT AS AN ANNOYANCE IN THE COMFORT OF THE RIDE, HOWEVER IF THEY CAN NOT IDENTIFY THE ISSUE HOW DO THEY KNOW IT IS NOT A SAFETY RISK.

WHEN REVERSE IS ACTIVATED AT NIGHT, THE BACKUP CAMERA COMES ON AT FULL BRIGHTNESS AND IS NOT DIMMABLE. THE BRIGHT SCREEN PREVENTS VIEW OF THE PASSENGER SIDE MIRROR AND SIGNIFICANTLY REDUCES VISIBILITY IN THE DRIVER SIDE MIRROR WHILE REVERSING. THE SCREEN CANNOT BE DEACTIVATED AND BLINDS THE DRIVER. THIS IS AN ONGOING ISSUE.

HAVE HAD THIS INTO THE DEALER AT THE FIRST OIL CHANGE AND COMPLAINED ABOUT TRANSMISSION SHIFTING ISSUES AND IT BEING UNSAFE TO DRIVE. COMPLAINTS ARE: HARD SHIFT, IT CLUNKS BOTH UPSHIFTING AND DOWNSHIFTING. GOING AROUND CORNERS FROM A STOP THE TRUCK WILL EITHER FALL ON ITS FACE OR JERKS YOU VIOLENTLY FORWARD. IN STOP OR GO TRAFFIC IT IS UNSAFE AND HAPPENS VERY FREQUENTLY- IT RANDOMLY ACCELERATES (JUMPS) QUICKLY ON ITS OWN WITH SLIGHT PEDAL PRESSURE TO THE POINT WHERE YOU CONSTANTLY HAVE TO BE AWARE AND HAVE YOUR FOOT NEAR THE BRAKE OR YOU CAUSE AN ACCIDENT BY REAR ENDING THE CAR IN FRONT, ITS AS IF THE TRANSMISSION ELECTRONICS GET CONFUSED ON HOW TO ACT. FEEL SHUDDERING FROM TRUCK'S MOTOR WHERE COLUMN SHIFT LEVER WOULD SHUDDER VIOLENTLY WHERE I WAS AFRAID IT WOULD VIBRATE OUT OF POSITION. ROUGH IDLE IS INCONSISTENT AT LOWER SPEED WHERE YOU SEE TACH GOING UP AND DOWN. STARTING COLD YOU GIVE IT AN EASY PEDAL TO MOVE AND WOULDN'T GO. TRANS DOESN'T KICK IN UNTIL YOU PRESS HARDER AND SOMETIMES WILL LUNGE. HAVE TAKEN INTO THE VARIOUS DEALERS 5-6 TIMES, VALVE BODY CHANGE, ENGINE MOTOR MOUNTS CHANGE AND DEALERS CAN FIND NO FIX. GM POWERTRAIN WAS EVEN INVOLVED WITH NO HELP. COMPLAINED TO THE GMC HOTLINE AND THEY SAID NEED 12,000 MILES ON TRUCK BEFORE THE TRUCK KNOWS HOW TO DRIVE BECAUSE OF THE 'SMART' TRANSMISSION WHERE IT LEARNS YOU'RE DRIVING HABITS. COMPLAINED THERE ARE 2 OF US THAT DRIVE IT HOW CAN IT LEARN EACH INDIVIDUALS DRIVING WHEN IT DOESN'T REALLY KNOW WHO IS DRIVING. THEY FINALLY SAID THERE IS NOTHING THAT CAN BE DONE FOR IT, THAT IS THE WAY IT IS. THIS ALL HAPPENS SPORADICALLY IN BOTH CITY LOW SPEED DRIVING AND HIGHWAY DRIVING, TURNING, BACKING UP OR GOING FORWARD FROM PARKING. BECAUSE OF THESE ISSUES, DIDN'T REALLY DRIVE THE TRUCK MUCH BECAUSE OF THE PROBLEMS.

THE "CHEVY SAKE". AT SPEEDS OVER 70MPH EXCESSIVE VIBRATION INSIDE THE VEHICLE. THIS IS WELL DOCUMENTED ON-LINE, PARTICULARLY VARIOUS GM FORUMS AND YOU TUBE VIDEOS. IT IS MY UNDERSTANDING THAT GM DENIES IT IS A PROBLEM, BUT THEY HAVE BEEN DOING SOME BUY BACKS AND IF YOU READ SOME OF THE DEALER BLOGS IT IS EVIDENT THAT GM KNOWS IT IS A PROBLEM.

TL* THE CONTACT OWNS A 2017 GMC SIERRA 1500. WHILE THE VEHICLE WAS IDLING AT A TRAFFIC LIGHT, IT BEGAN TO RATTLE. THERE WERE NO WARNING INDICATORS ILLUMINATED. THE VEHICLE WAS TAKEN TO FRESNO BUICK GMC (LOCATED AT 5515 N BLACKSTONE AVE, FRESNO, CA 93710, (559) 742-4113) WHERE AN UNKNOWN DIAGNOSIS AND REPAIR WERE PERFORMED; HOWEVER, THE FAILURE CONTINUED. THE MANUFACTURER WAS NOT NOTIFIED. THE FAILURE MILEAGE WAS 24,000.

THIS TRUCK IS A 3500 HD. I WAS PULLING A CAMPER ON A 1100 MILE TRIP. WITH 50 MILES LEFT I NOTICED THAT THE TRUCK WAS LEAKING TRANSMISSION FLUID FROM UNDER THE TRANSMISSION COOLER. UPON FURTHER INVESTIGATION I FOUND THAT THE RETURN HOSE FROM THE TRANS COOLER WAS POSITIONED SO THE IT RUBBED ON A FRAME COMPONENT WHICH CAUSED A HOLE TO RUB IN THE ALUMINUM TRANS COOLANT RETURN LINE. I NOTICED THIS WHEN THE TRUCK WAS PARKED RUNNING AT A REST AREA FOR AN HOUR BUT IT WAS OBVIOUSLY AN ONGOING ISSUE. HAD I NOT NOTICED IT WHEN I DID THIS CONDITION COULD HAVE CAUSED CATASTROPHIC FAILURE OF THE TRANSMISSION. THE DEALER SAYS THERE IS NO RECALL AND IT IS NOT UNDER WARRANTY. I CONSIDER THIS TO BE A SERIOUS DESIGN FLAW AND A MAJOR SAFETY ISSUE. I WAS ABLE TO GET TO MY DELIVERY STOP AND GET THE LINE PATCHED. IT IS AT THE DEALER FOR REPAIRS RIGHT NOW.

EXTREMELY HARD SHIFTS UP-AND-DOWN IN THE 1ST 2 GEARS FOLLOWED BY HESITATION AFTER STOPPING AND STARTING

I ALMOST KILLED A KID TODAY PARKING FOR A BASEBALL GAME. I WAS TRAVELING SLOWLY AND PARKING WHEN MY BRAKES BECAME HARD TO PUSH AND FAILED. TRUCK WENT OVER CURB AND TOWARD KID PUTTING ON HIS CLEATS AND NOT FACING ME. I WAS ABLE TO PUSH AS HARD AS I COULD AND IT STOPPED. I BACKED UP AND BRAKES WORKED AGAIN. I HAVE 46,000 MILES ON THE TRUCK. I AM NOW AFRAID TO DRIVE IT, BUT IT SEEMS THEY ARE WORKING AGAIN. IF THIS IS COMMON, GMC NEEDS TO TAKE CARE OF THIS. SOMEONE WILL SOON BE HURT SERIOUSLY!

MY WINDSHIELD WIPER FLUID ONLY SPRAYS OUT 30% OF THE TIME. USUALLY IN THE MORNING THEN ANY OTHER TIME OF THE DAY IT WILL NOT SPRAY OUT. THEY REPLACED THE PUMP AND THAT DID NOT FIX IT AND THEY WON'T DO ANYTHING ELSE AND NOW IT IS OUT OF WARRANTY. WHEN RUNNING LOWER RPMS DRIVING THE TRUCK IT BEGINS TO FEEL LIKE ITS SHAKING FORWARD AND BACKWARDS, LIKE A SHUDDERING FEELING. I HAVE READ ABOUT OTHER PEOPLE HAVING THIS PROBLEM AND IT DESCRIBES MINE PERFECTLY. I HAVE THE 8SPEED

TRANSMISSION HARSH 1-2 SHIFT WHEN IT IS UNDER LIGHT THROTTLE AND SOMETIME DOES NOT SHIFT OR MAKE NOSE. GMC DEALER ARE AWARE ABOUT THIS ISSUES ON ALL GM TRUCK MODEL OF 2015 TO 2017 WITH 8SPED TRANSMISSION SINCE APRIL 2017. I HAVE ATTACHED DOCUMENTS GIVEN BY DEALER.
