2015 Chevrolet Colorado Complaint Log

I WAS DRIVING ONTO AN EXIT RAMP AND FELT THE STEERING GET STIFF. THE INFORMACTION SCREEN ABOVE THE STEERING WHEEL FLASHED YELLOW LIGHTS AND THE MESSAGE "SERVICE POWER STEERING, DRIVE SAFELY". I PROCEEDED TO GRIP THE STEERING WHEEL HARDER AND SLOW DOWN TILL I COULD SAFELY PULLOVER. THE BACKUP CAMERA ALSO STOPPED WORKING, WHICH MAKES ME THINK THIS IS AN ELECTRICAL ISSUES SINCE THE CAR HAS ELECTRICAL POWER STEERING. ONCE I TURNED THE CAR OFF AND ON BACK TO NORMAL BUT THIS SEEMS TO BE AFFECTING OTHER 2015 COLORADO AND GMC CANYONS. DUE TO THE WEIGHT AND SIZE OF THIS VEHICLE THIS ISSUE CAN CAUSE A MAJOR AND FATAL ACCIDENT.

TRUCK TRANSMISSION DOES NOT DOWN SHIFT WHEN SLOWING DOWN AT TIMES OR WHEN TAKING OFF FROM A STOP LIGHT. RETURNED TO DEALER TWICE AND SECOND TIME THEY DID A SOFTWARE UPDATE BUT STILL DOING SAME PROBLEM. DEALER SAY'S TRUCK NORMAL. WAITING FOR AN ACCIDENT BECAUSE TRANSMISSION WILL NOT SHIFT CORRECTLY ALSO NOT SHIFTING CORRECTLY AT TIMES WHEN PASSING OTHER VEHICLES.

PURCHASED 2015 COLORADO JULY 2015.WE HAD IT IN FOR OIL CHANGES & A FEW TIMES REGARDING HESITATION OF ACCELERATION. SERVICE TECHS DID NOT TYPE COMPLAINT WHEN IN FOR OIL CHANGE ONLY WHEN BROUGHT IN SPECIFICALLY FOR ACCELERATION ISSUE. THEY STATED IT WAS OUR FAULT WE DID NOT READ THE WORK ORDER.IT IS NOT MY JOB TO READ A WORK ORDER IT'S THE SERVICE TECHS JOB TO ENTER EVERY COMPLAINT OR ISSUE ADDRESSED BY THE CUSTOMER. THE LAST SERVICE WAS WHEN I SPOKE TO SALES MANAGER WHO SET ME UP WITH SERVICE MANAGER & I WAS ASSURED ME A TECH WOULD DRIVE VEHICLE FOR A WEEK TO AND FROM DEALERSHIP APPROX 40 MILES PER DAY SO THEY COULD DIAGNOSE THE ISSUES.I HAD ADVISED ISSUE IS INTERMITTENT; THE REASON THEY COULD NEVER DUPLICATE WHILE IN FOR SERVICE. THEY MADE SURE TO STATE IT WAS RUNNING TO MANUFACTURER SPECS. THEY DROVE IT 10 MILES NOT 40 MILES A DAY FOR THE 7 DAYS THEY HAD IT.THEN SAID EXACTLY THAT IT WAS RUNNING TO MANUFACTURER SPECS. OF COURSE IT DID, YOU DID NOT DO WHAT YOU PROMISED WASTING MY TIME & KEPT MY VEHICLE FOR 7 DAYS JUST TO PACIFY ME. I TOLD THE SALES MANAGER WHAT HAPPENED WHO I PURCHASED THE 2015 COLORADO & MY 2014 CAMARO THAT I WOULD NEVER BUY ANOTHER CHEVY PRODUCT AS THEY WOULD NOT STAND BY THIS ISSUE, THEIR CUSTOMER OR THE LEMON LAW. TODAY MY HUSBAND IS IN AUSTIN TEXAS WITH HIS TRUCK IN THE SHOP AGAIN AS TRUCK NOW HAS A SERVICE ENGINE LIGHT ON; OF COURSE STILL HAS THE ACCELERATION ISSUES AS THAT WAS NEVER ADDRESSED OR FIXED.WE HAVE TO PAY $800.00 TO FIX ENGINE ISSUES ON A 2015 VEHICLE, THIS TIME NO WARRANTY EVEN THOUGH WE THOUGHT WE WERE GIVEN A 75K WARRANTY WHEN WE PURCHASED THE VEHICLE. THIS IS THE ONLY THING I CAN THINK OF DOING PRIOR TO RETAINING AN ATTORNEY TO FIGHT FOR THE LEMON LAW FOR A VEHICLE WE BOUGHT FOR 40K. WE HAVE HAD ISSUES WITH THIS VEHICLE SINCE PURCHASE & I AM HOPING I WILL GET A CALL FROM SOMEONE FROM THE NHTSA REGARDING THIS COMPLAINT!

VEHICLE BUCKS AND HESITATES WHEN PRESSING GAS PEDAL RIDING IN 6TH GEAR AT SPEEDS UP TO 50MPH. IF YOU GIVE IT GAS IT GETS WORSE AND FINALLY AFTER 5 SECS IT WILL DOWN SHIFT 2 OR 3 GEARS AND GO WAY TO FAST. I HAVE TAKEN IT TO DEALER TWICE AND THEY SAID TRANSMITION WAS STILL IN LEARNING MODE AND SHOULD CLEAR UP. WELL ITS AT 15,000 MILES AND STILL HAS PROBLEM. IF I PUT IT TOW MODE IT DOES NOT HAPPEN...SHIFT POINT CALIBRATION IS NEEDED BADLY ON THIS TRUCK

I STOPPED AT A STOP SIGN AND HEARD THE TRUCK WARNING CHIMES AND SAW A SERVICE POWER STEERING MESSAGE AND WHEN I TRIED TO MOVE THE WHEEL I COULDN'T TURN IT. I PUT THE TRUCK IN PARK AND SHUT IT OFF. WAITED A FEW SECONDS AND TURNED IT BACK ON AND I HAD POWER STEERING AGAIN.WAS ABLE TO GET IT BACK TO WORK AND CALLED AND HAD IT TOWED BACK TO CHEVY DEALER AND GET IT REPAIRED, (I THOUGHT). THEY SAID THEY HAD TO REPROGRAM THE POWER STEERING CONTROL MODULE. IT HAPPENED AGAIN TODAY WHEN MY DAUGHTER WAS DRIVING ON A TOWN ROAD CAME AROUND A SHARP CURVE AND LOST THE STEERING AGAIN. SHE WAS ABLE TO PULL OVER INTO A DRIVEWAY AND SHUT IT OFF AND WHEN IT STARTED BACK UP THE POWER STEERING WAS WORKING AGAIN.

THE POWER STEER IN FAILED AS I WAS DRIVING ABOUT 25MPH. I DROVE THE CAR TO THE DEALERSHIP. THE POWER STEERING BRIEFLY WORKED EACH TIME THE IGNITION WAS ACTIVATED, THEN WOULD FAIL MINUTES LATER. HAVE BEEN WITHOUT THE VEHICLE SINCE THAT DAY WITH CONFLICTING EXPLANATIONS . EITHER THE DEALER RECEIVED A BAD REPLACEMENT PART OR THE ENTIRE STEERING COLUMN REQUIRES REPLACING. THIS IS A VERY DANGEROUS DEFECT WHICH SHOULD BE INVESTIGATED

TL* THE CONTACT OWNS A 2015 CHEVROLET COLORADO. WHILE DRIVING AT VARIOUS SPEEDS, THERE WAS AN ABNORMAL NOISE COMING FROM THE FRONT DRIVER SIDE AIR BAG. THE VEHICLE WAS TAKEN TO A DEALER WHO WAS UNABLE TO DIAGNOSE OR REPAIR THE VEHICLE. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 2,000.

The contact owns a 2015 Chevrolet Colorado. The contact stated that while driving at various speeds, the transmission would intermittently hesitate upon the depression of the accelerator pedal without warning. The contact had taken the vehicle to a dealer and was informed that there were no defects with the vehicle and that the hesitation was normal vehicle operation. The manufacturer had also been notified of the failure but offered no assistance. The vehicle had yet to be repaired. The failure mileage was 15.

WAS STOPPED AT A RED LIGHT. WARNING SOUND CAME AND INSTRUMENT CLUSTER MENTIONED STABILITRAK AND POWER STEERING FAULT, DRIVE WITH CARE. HAD NO POWER STEERING FOR REST OF TRIP TO WORK. HAD THIS OF HAPPENED IN TRAFFIC AND IN A TURN I COULD HAVE EASILY HIT A CAR AS IT WAS EXTREMELY DIFFICULT TO TURN. TURNED OFF VEHICLE AND STARTED BACK UP AND EVERYTHING WAS FINE.

I BOUGHT A 2015 CHEVY COLORADO AT THE BEGINNING OF THE YEAR - SINCE THEN I WOULD ON OCCASION NOTICE A "SHUDDER" OR SLUGGISH ACCELERATION FOLLOWED BY SUDDEN BURST OF RPMS/ACCELERATION. AT ABOUT THE 3 MONTH MARK (AROUND 4500 MILES) MY TRANSMISSION FAILED AND WAS REPLACED. ABOUT A 3/4 OF A MONTH LATER I GOT MY TRUCK BACK AND CONTINUED TO NOTICE THE SAME SHUDDER AND ERRATIC BEHAVIOR. I BEGAN TO RESEARCH THE ISSUE AND FOUND MANY DRIVERS OF THIS AND THE GMC MODEL ARE ENCOUNTERING THE SAME ISSUE. I HAVE HAD TO NAG THE DEALERSHIP ABOUT THE ISSUE AND THERE EVENTUALLY WAS A TCM (TRANSMISSION CONTROL MODULE) SOFTWARE UPDATE WHICH SEEM TO MAX THE ISSUE WHICH IS BEGINNING TO MANIFEST ITSELF AGAIN. THE SHORT VERSION OF SYMPTOMS IS AS FOLLOWS: SUDDEN ACCELERATION AT SLOW SPEEDS (THIS CAUSED ME TO ALMOST HIT A MOTORCYCLIST IN SLOW MOVING TRAFFIC), ODD GEAR SHIFTING (OR LACK OF) GOING UP HILLS, OR GOING DOWN HILLS, SOMETIMES TURNING... ODD SHIFTING AT NORMAL SPEEDS (BUT NORMALLY ON HILLS). VIBRATION AT NORMAL DRIVING SPEEDS THAT SEEMS TO COME FROM UNDER THE TRUCK (NOT THE TIRES)? I'M FINDING THE TRUCK TO BE MORE AND MORE UNPREDICTABLE AND AM NOT SURE I WONT ENCOUNTER ANOTHER FAILURE IN THE NEAR FUTURE.

WHEN CONNECTED TO ANY ANDROID DEVICE THE STEERING WHEEL CONTROLS UPON PRESSING THE BACK SKIP BUTTON BRING UP A LARGE ERROR BOX ON THE MYLINK DISPLAY STATING THAT FUNCTION IS NOT AVAILABLE. THE ACTUAL SKIP BACKWARDS TAKES PLACE AND DOES INDEED WORK BUT THEN YOU HAVE TO TAKE EYES AWAY FROM ROAD TO HIT BUTTON ON SCREEN TO CLEAR ERROR BOX, THUS MAKING THE SAFETY OF USING THE STEERING WHEEL CONTROL BUTTON POINTLESS. ALL OTHER SKIP BACKWARDS BUTTONS ONSCREEN AND BELOW THE SCREEN WORK FINE WITH NO ERROR. THIS HAS BEEN TESTED ON MULTIPLE ANDROID DEVICES AND REGARDLESS OF THE DEVICE OR VERSION NUMBER CAUSES THE BOX TO DISPLAY WHEN USING THE SKIP BACK BUTTON ONLY ON STEERING WHEEL. SCANNING BLUETOOTH INPUTS COMING INTO DEVICE SHOW ALL 3 BUTTONS (MYLINK DISPLAY, BELOW DISPLAY, AND STEERING WHEEL) SEND THE EXACT SAME COMMAND TO THE ANDROID DEVICE AND WORK. BUT SOME REASON THE ACTUAL MYLINK SOFTWARE IS READING THE STEERING WHEEL BACK BUTTON AS ALSO ASKING FOR SOMETHING ELSE THAT BRINGS UP THAT ERROR BOX.

COLORADO HAS A GREAT DEAL OF HESITATION AT LOW SPEED WHEN ACCELERATION IS APPLIED. VEHICLE LURCHES, SHRUGS, SPARK KNOCKS, HAS DELAYED THROTTLE RESPONSE....SEEMS TO "CHUG" UNTIL A HEAVY THROTTLE IS APPLIED, THEN THE VEHICLE "JUMPS" TO A GEAR/RPM. VERY DANGEROUS WHEN TRYING TO ACCELERATE NORMALLY AND "GET OUT OF THE WAY" OF OTHER TRAFFIC OR JUST CLIMB A SLIGHT INCLINE. CHEVROLET DEALERSHIP SAYS THIS IS "NORMAL". THIS MAY BE NORMAL FOR CHEVROLET, BUT IT CERTAINLY IS NOT ACCEPTABLE FOR THE CONSUMER THAT WANTS A RESPONSIVE THROTTLE WHEN ACCELERATION IS REQUIRED...... THIS HAS BEEN AN ON-GOING ISSUE WITH THE TRUCK SINCE IT WAS PURCHASED NEW IN APRIL 2015.

TL* THE CONTACT OWNS A 2015 CHEVROLET COLORADO. WHILE DRIVING 20 MPH AND DOWNSHIFTING IN MANUAL MODE, THE VEHICLE LUNGED FORWARD. THE VEHICLE WAS TAKEN TO THE DEALER TO BE DIAGNOSED. THE CONTACT WAS INFORMED THAT THE VEHICLE WAS FUNCTIONING AS DESIGNED. THE CONTACT ALSO STATED THAT THE ACCESS DOOR SENSORS FAILED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURES. THE APPROXIMATE FAILURE MILEAGE WAS 90.

ON APRIL 2, 2015, MY DAUGHTER WAS PULLING OUT A SHOPPING CENTER IN PLAINFIELD IL WHEN THE POWER STEERING SYSTEM FAILED AS SHE TRYING TO MAKE A RIGHT TURN, THE IP DISPLAY SHOWED A MESSAGE TO DRIVE WITH CARE AND THAT THERE WAS A PROBLEM WITH THE POWER STEERING. I STOPPED AT AN AUTO PARTS STORE TO PURCHASE SOME FLUID AND WHEN RESTARTED THE ENGINE, THE STEERING RETURNED TO NORMAL. THE FOLLOWING MORNING, I TOOK IN TO THE WEBB CHEVROLET IN PLAINFIELD WHERE THEY SAID THE POWER STEERING RACK WAS DEFECTIVE AND THE PART WOULD NOT ARRIVE UNTIL APRIL 6TH OR 7TH. MY DAUGHTER PANICKED WHEN THIS HAPPENED AND SHE COULD HAVE EASILY RAN INTO ANOTHER VEHICLE IN THE OPPOSITE LANE OF TRAFFIC. THREE DAYS BEFORE I CAME TO ILLINOIS TO VISIT MY DAUGHTER I PICKED IT UP FROM MY LOCAL COLORADO FOR SEVERE ENGINE OIL LEAK REPAIR. *TR

TRANSMISSION DOES NOT DOWNSHIFT WHEN RPM'S FALL TO 1000 DUE TO SLOWING TRAFFIC, TURNING, ETC. WHEN TRYING TO ACCELERATE NORMALLY VEHICLE LUGS AND HESITATES AND WILL NOT ACCELERATE. IF THROTTLE IS SIGNIFICANTLY INCREASED THE TRANSMISSION DOWNSHIFTS SEVERAL GEARS AND ACCELERATES RAPIDLY. THE HIGHER THE LOAD ON THE VEHICLE (IE. A/C OR GOING UPHILL) AND THE HIGHER THE AMBIENT TEMPERATURE THE WORSE THE PROBLEM GETS. WHEN CRUISE CONTROL IN ENGAGED THE VEHICLE WILL SLOW DOWN AS MUCH AS 4 MPH BEFORE DOWNSHIFTING TO MAINTAIN SET SPEED. THIS IS A SAFETY HAZARD DUE TO LACK OF ACCELERATION WHEN REQUIRED AND ALSO SUDDEN RAPID ACCELERATION WHEN VEHICLE FINALLY DOES DOWNSHIFT. GENERAL MOTORS ENGINEERING STATES THAT THIS IS DUE TO DESIGN TO INCREASE FUEL MILEAGE AND REFUSES TO ADDRESS THE PROBLEM. THIS PROBLEM HAS BEEN PRESENT SINCE I PURCHASED THE VEHICLE NEW IN APRIL OF 2015.

SIMILAR TO OTHER COMPLAINTS, THE VEHICLE NEARLY STALLS WHEN TAKING OFF FROM A STOP. THE TRANSMISSION IS IN THE WRONG GEAR AND THE ACCELERATION IS VERY LIMITED UNLESS THE GAS PEDAL IS PUSHED DOWN FULLY. THIS CAUSES A VERY DANGEROUS SITUATION PARTICULARLY WHEN TURNING LEFT AT INTERSECTIONS AS THE VEHICLE WILL NEARLY STALL OR MOVE AT A VERY SLOW PACE.

I HAD A POWER STEERING MALFUNCTION ON THREE OCCASIONS ON FEBRUARY 13,16,AND 17. ALL THREE TIMES IT WAS -10 BELOW ZERO OR MORE AND LOST MY POWER STEERING. MY TRUCK IS PARKED IN A GARAGE AT NIGHT ,THIS HAPPENED ALL THREE TIMES AFTER BEING OUTSIDE FOR SEVERAL HOURS IN EXTREMEY COLD WEATHER. THE DRIVER INFO CENTER DISPLAYED (SERVICE POWER STEERING-- DRIVE WITH CARE). AFTER I HAD DRIVEN ABOUT 5 MILES AND SHUT THE TRUCK OF AND RESTARTED IT THE POWER STEERING WORKED. AT THIS TIME IT IS WORKING OK. I HAVE A SECOND APPOINTMENT ON MARCH 2ND WITH MY DEALER TO TRY AND FIX THIS ISSUE.

HOOD VIBRATES A LOT WHEN DRIVING DOWN THE HIGHWAY ( 50 - 80 MPH ) - ESPECIALLY ON THE DRIVERS SIDE. *TR

WHEN DRIVING AROUND 5 TO 8 MPH WHILE APPROACHING A TURN. VEHICLE RAN INTO VEHICLE IN FRONT OF ME. PEDAL WENT TO THE FLOOR AND WHEN TRYING TO MOVE THE VEHICLE TO THE SIDE OF THE ROAD NOTICED THE BRAKE PEDAL WAS LOCKED TO THE FLOOR. GM ENGINEER DIAGNOSED AS POWER BRAKE BOOSTER AND BRACKET. REPAIRING VEHICLE AT THEIR COST INCLUDING BODY DAMAGE. *TR

THE TRANSMISSION WON'T DOWNSHIFT WHILE TRYING TO ACCELERATE AFTER SLOWING DOWN. THE TRUCK WILL START TO VERY NOTICEABLY CHUG AND JERK AND NOT WANT TO GO FROM NOT DOWNSHIFTING WHEN BRAKING AND THEN TRYING TO ACCELERATE. I HAVE BEEN CLOSE TO GETTING REAR ENDED WHEN THIS HAPPENS AND TO AVOID IT I HAVE TO STOMP ON THE GAS PEDAL WHICH THEN CAUSES IT TO JERK ERRATICALLY FROM DOWNSHIFTING TOO FAR AND CAUSING ME TO ACCELERATE TOO FAST AND ALMOST REAR ENDING THE VEHICLE IN FRONT OF ME. THIS HAPPENS EVERY TIME I SLOW DOWN TO GO AROUND SOMEONE TURNING OR SLOWING DOWN TO STOPPED TRAFFIC AND THEN ACCELERATING AGAIN. WHILE DRIVING WITH MY WIFE AT AROUND THE 200 MILE MARK IT STARTED CHUGGING BADLY AND SHE THOUGHT WE WERE BREAKING DOWN. IT IS VERY EMBARRASSING WHEN SOMEONE IS RIDING WITH ME BECAUSE NO VEHICLE SHOULD ACT LIKE THIS. GM SHOULD BE ASHAMED OF THEMSELVES. I HAVE ABOUT 10,500 MILES ON MY TRUCK RIGHT NOW AND THIS ISSUE HAS BEEN A SERIOUS ISSUE SINCE I DROVE IT OFF THE LOT BRAND NEW. TOOK IT TO THE DEALER AND THEY SAID IT SHOULD TAKE A COUPLE SECONDS TO SHIFT FROM GEAR TO GEAR. ITS FUNNY BECAUSE I HAVE DRIVEN A LOT OF VEHICLES AND NONE OF THEM HAVE DONE THAT OR TOOK THAT LONG TO SHIFT. I KNOW THE TRANSMISSION IS SUPPOSED TO ADAPT TO YOUR DRIVING...WHICH SEEMS VERY UNNECESSARY TO ME BUT OBVIOUSLY IT IS NOT WORKING OUT FOR THE COLORADOS. ADAPTIVE TRANSMISSIONS NEED TO GO AND PUT A FIRM SPORTY SHIFTING TRANSMISSION IN THESE TRUCKS.

AT ABOUT 45-50 MPH THE DRIVER SIDE OF THE HOOD SHAKES BADLY. *TR

I WANTED TO REACH OUT TO YOU ON CHEVROLET?S CLAIM THAT THEIR ENGINE ACHIEVES 305 HORSEPOWER. WHILE IT MAY BE TRUE THAT THEIR ENGINE ACHIEVES THIS FIGURE IT DOES SO AT A STATED 6800 RPM. THE 6800 FIGURE IS IMPORTANT TO NOTE BECAUSE THE TRUCKS? RED LINE INDICATING POTENTIAL DANGEROUS OPERATING CONDITIONS START AT 6500 RPM. SO IN ESSENCE IN ORDER FOR AN OWNER TO ACHIEVE 305 HP THEY WOULD HAVE TO BE OPERATING THEIR TRUCK IN A POTENTIALLY DANGEROUS MANNER. EVEN IN THE 2015 COLORADO OWNER?S MANUAL IT INDICATES THE DANGER OF OPERATING ABOVE THE REDLINE? ?DO NOT OPERATE THE ENGINE WITH THE RPM?S IN THE WARNING AREA.? GM IS STATING THAT SOMEONE CAN ACHIEVE MAXIMUM HP ONLY BY OPERATING THE VEHICLE IN A DANGEROUS MANNER....REALLY?! I BELIEVE IT WILL ONLY BE FAIR FOR CHEVROLET TO RE-EVALUATE THEIR MAXIMUM HORSEPOWER PRIOR TO THEIR ENGINE HITTING THE REDLINE. *TR

PURCHASED TRUCK IN NOVEMBER 2014. CREW CAB Z71. HAD PROBLEMS RIGHT AT 200 MILES. THEY SAID THE TRANSMISSION HAS TO LEARN MY STYLE OF DRIVING. AT 2,00 MILES TRANSMISSION AND ENGINE STILL DON'T TALK TO EACH OTHER. I CAN ACCELERATE AND 5 SECONDS OR MORE LATER THE TRANSMISSION REACTS. IN HEAVY TRAFFIC, A COUPLE OF CARS GET BETWEEN ME AND THE CAR I WAS FOLLOWING BEFORE IT REACTS AND I HAVE TO SLAM THE BREAK. ALWAYS SEEMS TO BE IN THE WRONG GEAR. WILL CHUG A LOT UNTIL IT GETS UP TO THE SPEED FOR THAT GEAR. TOOK IT TO DEALER AT OIL CHANGE AND THEY RESET THE CONTROL MODULE. AFTER 2,000 MORE MILES, TOOK IT BACK BECAUSE IT STILL ACTED THE SAME WAY. TOOK TECH ON DRIVE AND WAS ABLE TO DUPLICATE ALL MY CONCERNS. HE SAID THAT THERE WAS NOTHING HE CAN DO AND THAT I NEEDED TO WAIT FOR ECM CALIBRATION FROM GM. HE SAID HE FELT BAD FOR ME. SURELY I WILL GET IN AN ACCIDENT BECAUSE OF THIS SLOW TRANSMISSION THAT IS ALWAYS IN THE WRONG GEAR. CURRENTLY I AM AT 7,000 MILES. THE ONLY THING THE TECH COULD SAY WAS NOT TO DRIVE IT IN STOP AND GO TRAFFIC....SERIOUSLY. CLEARLY THIS ADAPTIVE TRANSMISSION IS BULL CRAP AND GM PROBABLY KNOWS THEY HAVE A PIECE OF CRAP PROGRAMMING BUT CAN'T FIGURE IT OUT. PLEASE FIGURE OUT THIS SHIFTING PROBLEM, BECAUSE OTHER THAN THIS THE TRUCK IS NICE...TOO BAD, BECAUSE IF THEY DON'T SOMEONE WILL GET IN AN ACCIDENT AND HOPEFULLY IT WILL NOT BE FATAL. GET REAR ENDED BECAUSE IT DOESN'T ACCELERATE WHEN YOU NEED IT TO, OR IT FINALLY MOVES WHEN YOU ARE NEEDING TO BREAK. FIX THIS NOW OR AT SOME POINT YOU WILL PAY BIG....

SLUGGISH ENGINE AFTER SLOWING DOWN AND THEN TRYING TO INCREASE SPEED, ENGINE JUMPS AND HESITATES FOR A FEW SECONDS THEN IF YOU STOMP ON THE GAS PEDAL IT DOWNSHIFTS AND TAKES OFF AFTER REVING TO ABOUT 5,000 RPMS. THIS USUALLY HAPPENS WHEN SLOWING DOWN TO ABOUT 20-30 MPH THEN STARTING TO INCREASE SPEED. IT IS TRULY EMBARRASSING OWNING THIS $37,0000 TRUCK. DEALERSHIP AND GM CUSTOMER SERVICE STATED THAT THE ENGINE NEEDS TO LEARN HOW I DRIVE AND ADAPT. REALLY? THE ENGINE IS REMAINING IN TOO HIGH OF A GEAR AND NOT DOWNSHIFTING AND SUPPLYING THE ENGINE POWER THAT IS REQUIRED IN TRAFFIC. THIS PROBLEM HAS EXISTED SINCE I PURCHASED THE VEHICLE 11/1/14, I'VE IGNORED THE PROBLEM HOPING IT WOULD GO AWAY BUT HERE I AM.

AT ABOUT 50MPH AND HIGHER, THE HOOD OF THE TRUCK FLUTTERS. WITH GUSTY CROSS WIND, THE PROBLEM GETS WORSE. TOOK IT TO A DEALER TO BE SERVICED ON OCT 31ST, 2014 AND THEY COULDN'T FIGURE OUT THE PROBLEM AND TOLD ME THEY WILL CONTACT THE MANUFACTURE AND TRY TO GET FEED BACKS FROM THEM. *TR

VEHICLE LOOSES ACCELARATION ON TAKE OFF IT., NOT ALL THE TIME YOU DON'T KNOW WHEN ITS GOING TO HAPPEN . THIS IS DANGEROUS YOU HAVE TO BE VERY CAREFUL WHEN PULLING OUT FROM STOP POSITION OR CHANGING LANES THE TRUCK WILL LOOSE ACCELARATION .I HAVE ALMOST BEEN INVOLVED IN AN ACCIDENT BECAUSE OF THIS . IT WILL ALSO BUCK AS YOU ARE GOING DOWN THE ROAD. I HAVE HAD IT BACK TO COUNTRY CHEVROLET SEVERAL TIMES AND THEY HAVE ASKED ME TO WORK WITH THEM A LOT OF TIMES IT WAS NEVER DOCUMENTED. THE VEHICLE IS GOING TO GET ME OR SOMEONE KILLED. THIS TRUCK STARTED THIS FROM DAY 1
