ENGINE, POWER TRAIN, STEERING
NO TRANSMISSION POWER REGARDLESS OF THE GEAR SHIFTER POSITION. I TURNED THE ENGINE ON AND OFF SEVERAL TIMES TRYING TO GET A SOLUTION, NO LUCK. I RETURNED TO THE VEHICLE 5 MINUTES LATER AND DID GET IT TO MOVE,,,WOULD ONLY GO 25 MPH AT 3000 RPMS. I WAS IN THE MIDDLE OF WI NOT NEAR ANY MAJOR DEALERSHIP ON-STAR WAS USELESS SAYING I HAD A MAJOR ENGINE PROBLEM AND THE COMPUTER WAS TRYING TO PROTECT THE ENGINE. I WAS DIRECTED ME TO A CHRYSLER DEALER SHIP, WHO TOLD THEY COULD NOT GET ME IN FOR 2 WEEKS, SUGGESTED ANOTHER BRANCH WHICH WAS OVER 45 MILES AWAY. I DROVE 5 MILES TO A FRIENDS HOUSE AND WAS ABLE TO FIND A DEALERSHIP IN JANESVILLE, WI (FAGAN). WHEN I STARTED THE VEHICLE TO DRIVE TO JANESVILLE, THE TRANSMISSION DID WORK. FAGAN SPENT 2 HOURS WORKING ON IT, AND COULD NOT FIND A CAUSE FOR THE PROBLEMS, THEY CHECKED EVERY COMPUTER, COULD NOT DUPLICATE WHAT HAPPENED. THEY REPROGRAMMED ALL THE COMPUTERS. THEN IN CINCINNATI, OH THE POWER STEERING ASSIST WENT "OFF", WHILE STAIONARY. I TRIED RESTARTING SEVERAL TIMES TO NO AVAIL, DROVE THE 3 MILES LEFT TO THE G'KIDS HOUSE, NO POWER STEERING, TRAILER PROBLEM LIGHJT ON, NO RPM OR MPH NEEDLES MOVING. CALLED LOCAL DEALERSHIP (BORCHARDING) AND THEY SUGGESTED I DRIVE IT TO THEIR LOCATION 12 MILES AWAY. WHEN I STARTED IT, THE POWER STEERING WAS BACK ON, BUT THE UNIT WOULD NOT GET OUT OF 2ND GEAR, RAN 40 MPH AT 2500 RPM, WARNING LIGHTS ALL ON, ENGINE LIGHT STILL ON. NEXT MORING I STARTED THE VEHICLE, EVERYTHING WAS OKAY INCLUDING THE TRANSMISSION PROBLEM, BUT STILL HAD THE "CHECK ENGINE ON", THE DEALERSHIP KEPT IT (2) DAYS, INVOLVED GMC ENGINEERS, COULD NOT DETERMINE THE CAUSE FOR ALL THE PROBLEMS,INCLUDING LOSS OF "STEERING ASSIST". THEY DROVE IT OVER 50 MILES ON TWO TRIPS,COULD NOT DUPLICATE WHAT HAPPENED. THEY TOLD ME IT WAS SOME KIND OF COMPUTER PROBLEM, BUT COULD NOT DETERMINE, THEY RESET EVERYTHING AGAIN.

UPON STARTING THE ENGINE THE VEHICLE MAKES A CLANK SOUND AND EITHER SURGES FORWARD OR BACKWARDS SLIGHTLY. IT SEEMS TO DO IT MORE OFTEN ON A LIGHT INCLINE. LOCAL CHEVROLET ( GM) DEALER HAS LOOKED OVER TWICE, NO SUGGESTIONS MADE OR GIVEN TO ME.

FUEL/PROPULSION SYSTEM, POWER TRAIN
WHEN 1ST CRANKING TRUCK AND PUT IN DRIVE MOTORS RREV UP AND SHIFTS HARD TO SECOND. OCCASIONALLY WHEN I OUT IN REVERSE IT WILL SIT THERE N NOT SHIFT IN. THEN WHEN IT DOES IT SHIFTS HARD. WHEN ACCELERATING THE TRUCK IT SOUNDS LIKE A CLATTERING SOUND UNDER DRIVERS SIDE UNDER HOOD. TRIED DIFFERENT TYPE OF GASOLINE AND NOTHING CHANGES. GMAC NEEDS TO DO A RECALL ON BOTH OF THESE ITEMS. I AM VERY DISAPPOINTED IN MY GMC AND GMAC

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.

FUEL/PROPULSION SYSTEM, UNKNOWN OR OTHER
THE SIERRA SURGES FROM PARK TO REVERSE AND DRIVE. I BUMPED A VEHICLE TODAY, AND THE SURGE HAS BECOME AN ISSUE THIS WEEK AND THERE IS NOT EVEN 9,000 MILES ON THE TRUCK. THE AFM IS ROUGH SHIFTING BETWEEN V8 AND V4 MODE TOO. NONE OF THIS WAS AN ISSUE UNTIL RECENTLY. MY SPEAKERS ALSO VIBRATE LIKE A BLOWN SPEAKER ON HIGH DEFINITION RADIO, BUT NOT ON REGULAR RADIO STATIONS.

DOCUMENT ID 4605342 #16-NA-361 : INFORMATION ON TRANSMISSION HARSH 1-2 SHIFT UPON FIRST START UP/SHIFT OF THE DAY UNDER LIGHT THROTTLE THIS GM BULLETIN WAS ISSUED JUL 21, 2017 ON NUMEROUS VEHICLES AND ACCORDING TO THIS BULLETIN THE PROBLEM DOES NOT HAVE A RESOLUTION. THE BULLETIN CLEARLY STATES CHANGING THE ENTIRE TRANSMISSION WILL NOT SOLVE THIS ISSUE. THIS IS AFFECTING MY GMC WITH THE 8 SPEED TRANSMISSION. GM HAS KNOWN ABOUT THIS ISSUE BUT HAS NONE THE LESS SOLD THE VEHICLES TO CONSUMERS WITHOUT DISCLOSURE. NEITHER GM OR DARREL WALTRIP GMC IN FRANKLIN TN DISCLOSED THIS ISSUE PRIOR TO THE SALE. THE SERVICE DEPT AT THE DEALER ADMITTED THE ISSUE CANNOT BE REPAIRED AND TOLD ME GM IS UNWILLING TO DO A TRADE ASSISTANCE OR BUYBACK. GM CLAIMS NOTHING IS WRONG WITH MY CAR YET HAS A CLEAR DOCUMENT THAT SAYS OTHERWISE.

WHILE THE TRUCK IS IN MOTION AND WHEN ACCELERATING AROUND 15-20 MPH THE TRANSMISSION WILL SOMETIMES "HUNT" FOR A GEAR CAUSING THE TRUCK TO NOT ACCELERATE. THIS RESULTS IN A MILD JERKING OF THE TRUCK WHEN IT IS TRYING TO ACCELERATE AND FEELS LIKE THE TRANSMISSION IS SLIPPING/SKIPPING. THIS IS MORE APPARENT WHEN GOING UP A GRADE VERSUS ON A FLAT SURFACE. SO I HAVE TO PUSH HARDER ON THE GAS PEDAL WAITING FOR THE TRUCK TO SHIFT. THIS IS A SAFETY ISSUE SINCE WHEN NOT PROPERLY ACCELERATING INTO TRAFFIC, AN ACCIDENT IS MORE LIKELY TO OCCUR. I SEE THAT THIS ISSUE HAS ALREADY BEEN REPORTED IN ANOTHER INCIDENT ON YOUR WEBSITE. I HAVE HAD THIS ISSUE SINCE I BOUGHT THE TRUCK ON 02/2018 AND THE REASON I HAVE WAITED TO REPORT IS DUE TO THE DEALER STATING TO ALLOW THE COMPUTER TO UPDATE/LEARN YOUR DRIVING HABITS. I HAVE 11,000 MILES ON THE TRUCK NOW AND STILL EXPERIENCING THE ISSUE.
