2017 GMC Sierra 1500 complaints

AFTER COMING TO A COMPLETE STOP AT TRAFFIC STOP LIGHT TRUCK'S TRANSMISSION MADE A LOUD "CLUNK" SOUND. WHEN ATTEMPTING TO ACCELERATE ON THE GREEN LIGHT TRUCK, INITIALLY WOULD NOT MOVE THEN IT LERCHED FORWARD BUT WOULD NOT SHIFT OUT OF FIRST GEAR. PULLED OFF MAIN ROAD AND INTO A PARKING LOT WHERE I SHIFTED TRUCK INTO PARK AND TURNED OFF THE ENGINE. AFTER WAITING A COUPLE OF MINUTES I RESTARTED THE TRUCK, SHIFTED INTO DRIVE AND PULLED BACK ONTO THE STREET, BUT THE TRUCK STILL WOULD NOT SHIFT OUT OF FIRST GEAR.

THIS HAPPENED MULTIPLE TIMES. THE BRAKE PEDAL IS HARD AT LOW IDLE, AND YOU HAVE TO STAND ON BRAKE PEDAL TO STOP THE VEHICLE. TYPICALLY HAPPENS WHEN TRYING TO BACK IN A PARKING SPOT OR IN STOP & GO TRAFFIC THE BRAKE PEDAL BECOMES HARD TO PUSH AND TRUCK DOESN'T STOP AS QUICKLY

BACK WINDOW STARTED SMOKING NEXT TO HANDLE TO OPEN SLIDING WINDOW THEN SHATTERED THEN STARTED FALLING OUT. I WAS MOVING AND IN IN REVERSE BACKING UP WHEN THIS HAPPENED. (LEFT SECTION OF BACK WINDOW)

TL* THE CONTACT OWNS A 2017 GMC SIERRA 1500. THE CONTACT STATED THAT WHILE ACCELERATING AT 85 MPH, THE VEHICLE INDEPENDENTLY DECELERATED TO 70 MPH WITHOUT WARNING. THE CONTACT STATED THAT THE THROTTLE NO LONGER OPERATED AS NEEDED. THE CONTACT HAD TAKEN THE VEHICLE TO FAULKNER BUICK GMC TREVOSE (4427 E STREET RD, FEASTERVILLE-TREVOSE, PA 19053) ON TWO OCCASIONS HOWEVER, THE MECHANICS WERE UNABLE TO DIAGNOSE THE FAILURE. THE MANUFACTURER WAS ALSO NOTIFIED OF THE FAILURE AND INFORMED THE CONTACT THAT THEY HAD NEVER HEARD OF SUCH A FAILURE. THE CONTACT THEN SPOKE TO AN INDEPENDENT MECHANIC WHO INFORMED HIM THAT THE DEFECT MAY BE LINKED TO A SPEED SENSOR AND A COMPUTER MALFUNCTION. THE CONTACT THEN TOOK THE VEHICLE TO ANOTHER INDEPENDENT MECHANIC WHO REPROGRAMMED THE COMPUTER SOFTWARE. THE VEHICLE WAS REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 19,906.*DT*JB

I WAS DRIVING 50MPH AND WAS BEHIND A SEMI AS I STARTED TO PASS HIM I NOTICED AN ONCOMING CAR AND DECIDED THERE WASNT ENOUGH TIME TO PASS SO I STARTED TO PUSH THE BRAKE PEDAL TO SLOW DOWN AND GET BACK BEHIND THE SEMI AND THE BRAKES LOCKED UP WHICH PRODUCED AN UNCONTROLLABLE SPIN IN WHICH I DID A 180 DEGREE SPIN AND ENDED UP GOING INTO THE DITCH BACKWARDS AND TIPPED OVER ON MY SIDE NO AIRBAGS DEPLOYED EITHER.

MY TRANSMISSION SHIFTS VERY HARD FROM 1ST GEAR TO 2AND AND THEN FROM 2AND GEAR TO 1ST GEAR AT WHICH TIME I'M USUALLY STOPPING AND IT SEEMS TO PUSH THE TRUCK FORWARD A BIT. I'VE TAKEN IT TO PEKIN IL DEALERSHIP AND GREEN CHEVROLET IN PEORIA IL AND NEITHER ONE SAYS THERE IS ANYTHING WRONG

WHEN I APPLY THE BRAKES IT DOESN'T WANT TO STOP AND I HAVE TO PUSH IT DOWN AGAIN ALMOST LIKE THERE IS A ISSUE WITH THE VACUUM ON THE BRAKES BUT IT SAYS MY VEHICLE IS NOT AFFECTED BY THE RECALL BUT THE SYMPTOMS ARE EXACTLY THE SAME AS THE RECALL.

I HAVE AN 8 SPEED TRANSMISSION THAT STALLS UPON ACCELERATION LURCHES AND SURGES WHEN TRYING TO SHIFT GEARS. WHEN COMING TO A STOP LUNGES FORWARD DUE TO A SHIFT IN THE TRANSMISSION. I HAVE TAKEN TO THE DEALER MULTIPLE TIMES AND EXPRESS MY CONCERNS THEY FINALLY REPLACED TORQUE CONVERTER AND FLUSHED TRANSMISSION NOW THEY STATE THAT IT IS OPERATING CORRECTLY.

VEHICLE HAS HARD SHIFT BETWEEN FIRST AND SECOND GEAR ACCELERATING AND DECELERATION. I NOTICED IT AFTER ABOUT A WEEK OF DRIVING IT AFTER PURCHASE

THE VEHICLE DOES A HARD SHIFT FROM 1 TO 2 SECOND AND HAS A SHUDDER.

WHILE WATCHING THE ECONOMY MILEAGE WINDOW I NOTICED IN THE LOWER RIGHT SIDE SHOWING V6 AND V4 SWITCHING BACK AND FORTH. AS THEY WERE SWITCHING, I NOTICED THE ENGINE VIBRATING WHILE SHOWING THE V4 IN THE WINDOW. IT DID NOT VIBRATE WHILE SHOWING THE V6 IN THE WINDOW. IT DID THIS WHILE I WAS DRIVING 65 MPH(ON CRUISE) ON THE EXPRESSWAY. I DID NOT NOTICE IT DURING DRIVING IN START-STOP SLOWER TRAFFIC.THIS HAS BEEN HAPPENING BEFORE, BUT DID NOT FIGURE OUT THE PROBLEM UNTIL NOW.

AS I WAS BACK MY BOAT IN AT BOAT RAMP BRAKE PEDAL WAS HARD TO PRESS DOWN HAD TO ALMOST STAND ON THEM TO KEEP FROM TRUCK GOING IN THE WATER. I RESEARCHED THIS AND SEEN WHERE GM HAS A RECALL ON THE VACUUM PUMP BUT I CALL THE DEALER THEY TOLD ME THEY WASN'T A RECALL.

THE VEHICLE WAS IN MOTION ON A CITY STREET, WHEN THE VEHICLE COMPLETELY POWERED OFF. THE STEERING WHEEL LOCKED. THIS OCCURRED ON 11/22/2020 AND 11/23/2020. THE FOLLOWING MESSAGE IS ON MY DASHBOARD 'STEERING ASSIST IS REDUCED DRIVE WITH CARE.'

GMC SIERRA WAS BROUGHT TO DEALER FOR EXISTING RECALL REGARDING BRAKING. DEALER INDICATED RECALL HAD BEEN RESOLVED. WHILE BACKING THE TRUCK ON 3 SEPARATE OCCASIONS SINCE RECALL ADDRESSED, BRAKES BECOME MUCH LESS RESPONSIVE WITH CLICKING SOUND. BRAKES BECOME HARD TO PRESS AND DO NOT STOP VEHICLE COMPLETE. THIS ALSO HAPPENED WHILE TOWING A BOAT DOWN RAMP. THE VEHICLE HAS 28,000 MILES AND THE ISSUE DID NOT OCCUR PRIOR TO ABOUT A MONTH AGO. THE MOST RECENT TIME WAS TONIGHT WHILE BACKING ON LEVEL GROUND INTO GARAGE. I HAVE NOT HAD AN ACCIDENT AS A RESULT OF THIS, BUT THE RECALL WAS NOT ADEQUATELY PERFORMED OR DID NOT ADDRESS THE ISSUE.

TL* THE CONTACT OWNS A 2017 GMC SIERRA 1500. THE CONTACT STATED THAT WHILE EXITING A PARKING LOT AND TURNING THE STEERING WHEEL COMPLETELY TO THE LEFT AND TO THE RIGHT, THERE WAS AN ABNORMAL SOUND COMING FROM THE DRIVER'S AND PASSENGER'S WHEELS. THE CONTACT COASTED TO THE SIDE OF THE ROAD AND NOTICED THE TIRES WERE RUBBING ON THE FRONT SUSPENSION BARS. THE VEHICLE WAS NOT TAKEN TO A DEALER. NEITHER THE DEALER NOR THE MANUFACTURER WERE MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 70,000.

ON FRIDAY NOVEMBER 6TH WE WERE ON OUR WAY HOME COMING DOWN 1960 EAST WHEN WE STARTED TO HEAR A NOISE COMING FROM THE TRUCK. WE COULD HEAR IT LOUD AND CLEAR BECAUSE THE A/C IS ALSO OUT SO WE HAVE BEEN HAVING TO LEAVE THE WINDOWS DOWN. IT SOUNDED LIKE AN OLD ELECTRIC FAN RUNNING. THEN SHORTLY AFTER THE TRUCK STARTED TO JERK HARD IT FELT LIKE WE HAD JUST BEEN IN AN ACCIDENT. THE TRUCK WOULD NOT SHIFT GEARS AND WE WERE IN THE MIDDLE OF A VERY BUSY 1960 LUCKY WE WERE CLOSE TO HOME AND WHERE ABLE TO MAKE IT THERE AFTER MULTIPLE ATTEMPTS TO GET THE TRUCK GOING. MY HUSBAND HAS SOME KNOWLEDGE OF CARS AND REALIZED IT WAS THE TRANSMISSION. THIS IS A FAIRLY NEW VEHICLE. HOW CAN IT HAVE SUCH A MAJOR PROBLEM? WHEN DOING SOME RESEARCH APPARENTLY THIS IS PROBLEM THAT GM IS AWARE OF AND HAVE DONE NOTHING TO FIX. AS I MENTIONED BEFORE THE A/C CONDENSER HAS A MAJOR LEAK AND THIS IS ALSO A PROBLEM OF GM VEHICLES. BASICALLY WE BOUGHT A BRAND NEW LEMON. I'M THANKFUL WE WERE NOT ON THE FREEWAY WHEN THIS HAPPENED IT COULD HAVE BEEN MUCH WORSE OUTCOME. FOR NOW WE ARE WITH OUT A VEHICLE AND CAN NOT AFFORD TO REPLACE THE TRANSMISSION.

THE TRUCK LOOSE POWER WHEN KEY IS TURNED OFF AND THEN COME BACK ON AFTER A FEW MINUTES ALSO STABILATRACK SYSTEM IS SHUTTING OFF TRUCK ONCE ON THE HIGHWAY AT 70 MPH ENGINE RUNS RUFF AND USES OIL IN LESS THAN 5000 MILES HAS USE AT LEAST 3 QUARTS THE DOD SYSTEM MAKE TRUCK RUN EXTREMELY BAD ENGINE HAS MISS IN IT ALSO IT IS BECOMING UNSAFE TO DRIVE AT TIMES AND BRAKE PEDAL IS VERY HARD TO PUSH

ASSISTED BRAKING ISSUES. WHEN GOING DOWN A HILL DOESN'T KICK IN OR SLOWING DOWN. COMES ON ONCE IN AWHILE.

AT LOW SPEED OR MOST OF THE TIME BACKING UP BRAKES DO NOT WORK WELL AT ALL. NEED TO PUSH VERY HARD.

THE VEHICLE FIRST STARTED VIBRATING AT HIGHWAY SPEEDS WHILE STILL UNDER WARRANTY (~15K MILES) - I TOOK IT INTO THE DEALERSHIP AND THEY SAID IT WAS JUST OUT OF ALIGNMENT - ALIGNED AND ROTATED TIRES. THIS SEEMED TO IMPROVE THINGS FOR A FEW MONTHS UNTIL THE VIBRATION WAS BACK TO THE UNTOLERABLE STATE - UPON TAKING TO ANOTHER SERVICE STATION, THEY BLAMED THE TIRES (UNEVEN WEAR) AND I PAID FOR ALL NEW TIRES - ONLY FOR THE VIBRATION TO RETURN AFTER ANOTHER FEW MONTHS. I NEXT TOOK IT A 3RD SERVICE STATION AND THEY ARE CLAIMING A BEND WHEEL THAT WONT FULLY BALANCE. AFTER RESEARCHING, I NOW SEE THAT THIS IS A VERY COMMON ISSUE WITH A FAULTY DRIVETRAIN, BUT GMC IS NOT ACKNOWLEDGING THE ISSUE?? HOW DO I BECOME PART OF A CLASS ACTION LAWSUIT IN ORDER TO GET THIS ISSUE FIXED PROPERLY?

RADIATOR LEAKING AND HAD TO BE REPLACED.

VEHICLE SLAMS INTO GEAR AT INITIAL TAKE OFF AND DECELERATION FOLLOWING AN ACCELERATION WHICH CAUSES A HARD FORWARD JERK . THIS ISSUE HAS CAME CLOSE TO CAUSING ACCIDENTS ON THE HIGHWAY DURING PASSING AND DEPARTING STALLS ADJACENT OTHER VEHICLES AND/OR OBJECTS.

TRANSMISSION SHIFTS OR JERKS HARD WHEN COMING TO A STOP, SEVERE TRANSMISSION VIBRATION OCCURS WHEN TRAVELING AT SPEEDS OF 50 TO 65 MPH.

I WAS DRIVING ON I-4 TOWARDS ORLANDO AT 70MPH FOLLOWING A SAFE DISTANCE TRAFFIC WAS COMING TO STOP AND I WENT TO BRAKE AND THE BRAKES WOULDNT WORK PROPERLY AND CAUSE ME TO PULL VEHCILE TO ONE SIDE CAUSING ME TO CRASH SAW LIFE FLASH BEFORE EYES . THANKFUL TO BE ALIVE , COMES TO FIND OUT THERE WAS A RECALL ON IT

ALMOST COLLIDED WITH OTHER CARS IN PARKING LOT BECAUSE THE BRAKES WEREN'T WORKING RIGHT ALSO TRANSMISSION SHIMMIES BETWEEN 50 AND 60 MPH

WHEN STATIONARY I PUSHED IN ON THE GAS THROTTLE TO GO IT DIDN'T GO SO I PUSHED IN A LITTLE MORE AND IT ACCELERATED TO FAST THEN LIKE IT JUMPS. IT ALSO IS SHAKING AT CERTAIN SPEEDS.

THERE IS A STRONG INTERMITTENT VIBRATION IN THE STEERING COLUMN WHEN AT SPEEDS OF 35-70 MPH. IT RESEMBLE DRIVING OVER "RUMBLE STRIPS"

FELT STRANGE BRAKE PULSE TURNED INTO PARKING LOT AND POWER BRAKING FAILED. BARELY GOT TRUCK STOPPED BEFORE HITTING ANOTHER CAR. TRUCK HAD TO BE TOWED TO DEALERSHIP

WHEN I GOING IN REVERSE THE PEDAL BRAKE DOENST WORK

WAS PULLING MY TRAILER OUT OF THE WATER AND LOST ALL POWER STEERING, FLUIDS FULL, PUMP WORKING, JUST ELECTRICAL ISSUE. HAD TO DRIVE HOME 20 MILES WITHOUT POWER STEERING, VERY HARD TO TURN. THEY SAID THEY 'FIXED' THIS IS ISSUE IN 2015, BUT HERE I AM IN A 2017 WITH THE SAME PROBLEM, LOW SPEED AND COMPLETELY LOST POWER STEERING, THANK GOODNESS I WASN'T PULLING ON TO A HIGHWAY OR IN THE MIDDLE OF A CURVE.

MY TRUCK BRAKING SYSTEM IS GOING TO THE FLOOR BOARD OF MY TRUCK. MAKING VERY HARD FOR ME TO STOP. THEY CALL THEMSELVES FIXING IT BUT THE SAME PROBLEM IS BACK. REALLY TIRED OF THIS PROBLEM AND OTHER SPEND 1000.00 ON SPRINGS AND THE VEHICLE WAS ONLY A 1 1/2 OLD WAS TOLD THE WARRANTY ON COVER IT IF THEY WERE BROKEN A LIE THE DEALERSHIP TOLD ME.

TL* THE CONTACT OWNS A 2017 GMC SIERRA 1500. THE CONTACT STATED THAT WHILE DRIVING 35 MPH, THE AIR CONDITIONER STARTED BLOWING HOT AIR INSTEAD OF COLD AIR. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC AND THE CONTACT WAS INFORMED THAT A LEAK WAS FOUND ON THE A/C COMPRESSOR. THE CONTACT REACHED OUT TO BOB STALL CHEVROLET LOCATED AT 7601 ALVARADO RD, LA MESA, CA 91942, (619) 460-1311, AND NOTIFIED THE DEALER OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER HAD BEEN INFORMED OF FAILURE. THE FAILURE MILEAGE WAS 50,000.

MY TRUCK IS JUST OUT OF WARRANTY, BUT AFTER 3 YEARS ONLY 15,000 MILES. CHK ENGINE LIGHT COMES ON, DEALER SAYS 3 BAD FUEL INJECTORS. DEALER HAS SEVERAL OTHER TRUCKS WITH THE SAME PROBLEM. OBVIOUSLY A MANUFACTURE PROBLEM THAT I SHOULDN'T HAVE TO PAY FOR. ALSO IS THIS AN EMISSION SYSTEM PROBLEM?

ON MAY 26, 2020, MY 2017 TRUCK'S CHECK ENGINE LIGHT APPEARED. VEHICLE IS IN ORIGINAL MANUFACTURER'S WARRANTY WITH 25,000 MILES, + OR -. TRUCK DRIVEN INFREQUENTLY DURING "STAY-AT-HOME PERIOD. TOOK TO GMC DEALER IMMEDIATELY; READ CODE; INDICATES ALL 8 FUEL INJECTORS OUT OF TOLERANCE.CAN'T EXPLAIN WHY OR PROVIDE IMPACT TO VEHICLE IF DRIVEN IN THIS CONDITION. CAN'T BE DRIVEN; DEALER PROVIDED LOANER. CAN'T ADVISE IF VEHICLE'S ENGINE WILL CUT-OF IF DRIVEN CAUSING UNKNOWN ISSUES. FUEL INJECTORS ARE ON BACK ORDER-NO ESTIMATE OF RECEIPT DATE! ANOTHER 2017 GMC TRUCK THERE WITH SAME ISSUE-BEEN THERE FOR LONGER PERIOD. GM WILL NOT ADVISE DEALER WHEN FUEL INJECTORS WILL BE RECEIVED. DELAY POSSIBLY ASSOCIATED WITH GM STRIKE OR VIRUS. IF TWO OR MORE VEHICLES HAVE PROBLEM, IS PATTERN OR PRACTICE-A SYSTEMIC ISSUE. GM CUSTOMER ASSISTANCE CAN NOT PROVIDE INFORMATION. DIFFICULT TO CONTACT GM CORPORATE OFFICES FOR ASSISTANCE. TODAY IS THREE WEEKS WITHOUT MY VEHICLE, WHICH I NEED. GM IS NOT PROVIDING ADEQUATE (ANY) INFORMATION TO ITS DEALER. THIS OUT OF TOLERANCE FUEL INJECTOR SITUATION HAS BEEN NOTED ON GM OWNER WEBSITES; IT IS NOT UNUSUAL. *TR

THE SAME ISSUE AS GM SERVICE BULLETIN PI1513F (RADIATOR LEAK) HAS HAPPENED ON MY 2017 GMC SIERRA. THIS SERVICE BULLETIN CURRENTLY COVERS 2014 - 2016 MODELS AND NEEDS TO BE EXTENDED TO COVER 2017 MODELS (AND POSSIBLY 2018). THIS ISSUE IS A RADIATOR THAT LEAKS ON THE PASSENGER OR DRIVERS SIDE ON THE WALL BETWEEN THE COOLING FINS AND THE END OF THE RADIATOR. *TR

OUR TRUCK IS LESS THAN THREE YEARS OLD WITH APPROXIMATELY 69000 MILES. THE TRANSMISSION JUST STARTED SLIPPING OUT OF THE BLUE WHILE DRIVING THRU A NEIGHBORHOOD. WHILE IN DRIVE IT WOULD MOVE BUT ONCE ACCELERATING IT WOULD REV UP AND NOT CHANGE GEARS. THIS HAPPENED WITHOUT WARNING, WITHOUT AN ENGINE OR WARNING LIGHT. WE DO ALL THE NECESSARY REGULAR MAINTENANCE. IN ADDITION TWO YEARS AGO WHILE THE TRUCK WAS A YEAR OLD, THE BRAKES WENT OUT WHILE DRIVING ON THE INTERSTATE. I GUESS IT WAS THE BRAKE VACUUM PUMP OR WHATEVER THAT DIDN'T ALLOW THE BRAKE PEDDLE TO BE PRESSED WHICH PROVIDED ME WITH NO BRAKES. AGAIN WITH ABSOLUTELY NO WARNING! THIS LATER BECAME RECALL ISSUE BUT NOT BEFORE IT HAD ALREADY HAPPENED TO ME! I UNDERSTAND THERE IS A CLASS ACTION LAW SUIT AGAINST GMC FOR TRANSMISSION PROBLEMS AND I WOULD CONSIDER BEING A PART OF THIS. THIS IS A 50;000$ AND RELATIVELY NEW TRUCK, THIS IS UNACCEPTABLE! THE DEALER NOW WANTS OVER 4000$ FOR REPAIRS. *TR

EXCESSIVE SHAKING IN THE STEERING WHEEL. *TR

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

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

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.

DEALER HAS REPROGRAMMED THE SOFTWARE PER GM, CHANGED THE TRANSMISSION FLUID TO NO AVAIL. DEALER HAS BEEN GREAT IN TRYING TO FIND AND REPAIR ISSUE BUT ALL THEY TELL ME IS GM IS AWARE OF ISSUE BUT DOES NOT KNOW WHAT TO DO. THE ONLY THING THEY ARE ALLOWED IS TO REPROGRAM THE SOFTWARE AND SEND IT HOME. THE DEALER HAS EVEN TOLD ME THEY HAVE SEVERAL CUSTOMERS WITH THIS ISSUE IN ONLY THE 8 SPEED TRANSMISSION.
