ENGINE
MY RADIATOR HAS DEVELOPED A LEAK AND COOLANT IS ESCAPING WHEN ENGINE IS HOT. THE ISSUE APPEARS TO BE VERY SIMILAR TO THE INCIDENTS WITH THE 2014-15 MODEL YEAR ISSUE. THE PROBLEM WAS DIAGNOSED TO BE A LEAKING RADIATOR NEAR THE TOP RIGHT SIDE BY AN INDEPENDENT MECHANIC. *TR

SERVICE BRAKES
I OWN TWO GMC SIERRA TRUCKS YEARS 2014 AND 2017 BOTH TRUCKS HAVE SEVERE LOCK UP ISSUES. I HAVE GONE TO THE DEALERSHIP NUMEROUS TIMES AND THEY RESET THE COMPUTER BUT THE BRAKES STILL LOCK UP. THIS IS AN EXTREME SAFETY HAZARD, AND MY WIFE AND I ARE EXTREMELY SCARED THAT WE WILL BE IN A FATAL ACCIDENT. THERE HAS BEEN SEVERAL TIMES WHERE WE HAVE ALMOST HIT A CAR OR PERSON WALKING. I AM REALLY CONCERNED THAT THESE VEHICLES WILL CAUSE AN ACCIDENT. MY CHILDREN ARE ALWAYS IN MY TRUCKS END IT IS EXTREMELY SCARY WHEN EVERY TIME I HIT THE BRAKES I AM NOT SURE IF IT WILL STOP OR NOT. THIS IS AN IMPERATIVE MATTER. *TR

POWER TRAIN
I HAVE BEEN EXPERIENCING THE HARD UP SHIFT AND DOWN SHIFT PROBLEMS THAT HAS AFFECTED ALMOST ALL GMC SIERRA PICKUPS WITH THE GM 8L90 AND 8L45 TRANSMISSIONS SINCE 2015. THE DEALERSHIP TOLD ME THAT THERE WAS NO REPAIR FOR THE PROBLEM AND RESET THE TRANSMISSION COMPUTER ON 5 SEPARATE OCCASIONS WHICH DID ABSOLUTELY NOTHING TO REMEDY THE PROBLEM. MY VEHICLE IS NOW OUT OF WARRANTY AND THE DEALERSHIP WANTS TO CHARGE ME $2800 TO REPLACE THE VALVE BODY IN THE TRANSMISSION. WHAT IS THE NHTSA GOING TO DO ABOUT THIS ISSUE AND WHY HASN'T GMC BEEN FORCED TO RECALL THESE VEHICLES.

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.

STRUCTURE:BODY, SERVICE BRAKES, SUSPENSION
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.

ENGINE
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].

POWER TRAIN
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.

SERVICE BRAKES, SEATS
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.

SERVICE BRAKES
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.

SERVICE BRAKES
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!

POWER TRAIN
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.

SERVICE BRAKES
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.
