2017 Chevrolet Colorado complaints

ON 25 OCTOBER 2019, WHILE MOVING FORWARD AFTER BACKING OUT OF THE PARKING SPACE AT MY WORK, THE TRUCK BEGAN AN UNCOMMANDED TURN TO THE LEFT. WITH SIGNIFICANT FORCE I WAS ABLE TO STRAIGHTEN THE STEERING WHEEL. IN LIGHT OF THE POTENTIAL LACK OF STEERING CONTROL, I HAD THE TRUCK DELIVERED TO THE COURTESY GMC DEALERSHIP IN LAFAYETTE, LOUISIANA FOR REPAIR. ACCORDING TO THE REPAIR RECEIPT, THE ELECTRIC BELT DRIVE RACK AND PINION STEERING GEAR WAS REPLACED AND THE TRUCK WAS RETURNED TO ME ON 30 OCTOBER 2019. ON 22 NOVEMBER 2019, AGAIN WHILE DRIVING THROUGH THE PARKING LOT AT MY WORK THE TRUCK WENT INTO AN UNCOMMANDED LEFT TURN. THE ACTIONS OF THE TRUCK WERE NEARLY IDENTICAL AS I EXPERIENCED IN THE FIRST TRUCK LOSS OF CONTROL EVENT. I DELIVERED THE TRUCK TO COURTESY GMC IN LAFAYETTE, LOUISIANA. WHEN THE CUSTOMER SERVICE ADVISOR TURNED THE TRUCK INTO THE SERVICE BAY, A LOUD METAL-TO-METAL SOUND WAS HEARD FROM THE FRONT OF THE TRUCK. ON 4 DECEMBER 2019, I MET WITH THE CUSTOMER SERVICE ADVISOR AND THE AUTOMOTIVE TECHNICIAN AT THE COURTESY GMC DEALERSHIP TO DISCUSS THE STATUS OF THE TRUCK. THE AUTOMOTIVE TECHNICIAN STATED THAT HE WAS GOING TO CONTACT GMC ABOUT THE ISSUE THE NEXT MORNING. ON 5 DECEMBER 2019, I WAS CONTACTED BY THE AUTOMOTIVE TECHNICIAN WHO INFORMED ME THAT HE HAD DISCUSSED THE ISSUE WITH AN ENGINEER AT GENERAL MOTORS CORPORATION. THE ENGINEER ADVISED THE AUTOMOTIVE TECHNICIAN TO REPLACE THE PART THAT WAS PREVIOUSLY REPLACED, BUT ORDER THE PART THROUGH A DIFFERENT PARTS WA

TRANSMISSION IS STUTTERING RANDOMLY EVERY MINUTE OR SO, IT VIBRATES THE CAR AND FEELS LIKE I'M RUNNING OVER RUMBLE STRIPS.

I AM EXPERIENCING DIFFICULTY REMOVING MY KEY FROM THE IGNITION SWITCH AFTER TURNING OFF THE VEHICLE. THE KEY BECOMES STUCK AND WILL NOT RETRACT. I HAVE TO START THE VEHICLE AGAIN AND THEN ATTEMPT TO SHUT IT DOWN IN HOPES THAT I CAN REMOVE THE KEY. VARIOUS ATTEMPTS ARE MADE AND I'VE FOUND THAT IF I TURN THE IGNITION SWITCH OFF "QUICKLY", THE KEY WILL COME OUT. I HAD ONE INCIDENT WHERE THE KEY WOULD NOT COME OUT AND I HAD TO SECURE MY VEHICLE WITH THE KEY FOB BUT LEAVING MY KEYS IN THE IGNITION SWITCH AND POSSIBLY ALLOWING SOMEONE TO BREAK INTO MY VEHICLE AND STEAL IT WHICH I SHOULDN'T HAVE TO DO. THIS ISSUE IS BECOMING VERY FRUSTRATING. I'M SCHEDULING AN APPOINTMENT WITH A LOCAL CHEVY DEALER TO SEE IF THEY CAN RECTIFY THE PROBLEM.

I WAS TURNING INTO AN APARTMENT COMPLEX PARKING LOT IN NOTED VEHICLE WHEN THE VEHICLE SUDDENLY ACCELERATED SENDING ME INTO THE SIDE OF THE APARTMENT BUILDING. I WAS IN THE PROCESS OF APPLYING THE BRAKE WHEN THIS OCCURRED. THERE WAS NO TIME TO REACT OR AVOID THE SIDE OF BUILDING AND I INCURRED DAMAGE TO BOTH MY VEHICLE AND THE SIDE OF THE BUILDING.

2017 COLORADO, 19632 MILES, HARD UP/DOWN SHIFTS TO FIRST GEAR AND SHUDDERS WHILE DRIVING, FOUND BULLETIN 18NA355, DEALER HUFFINES CHEVROLET PLANO TX REPLACED TRANSMISSION FLUID PER BULLETIN AND RESOLVED SHUDDERING ISSUE BUT NOT HARD SHIFTING IN AND OUT OF FIRST GEAR AND DEALERSHIP WILL NOT RETURN CALLS TO RESOLVE PROBLEM.

TRANSMISSION SHUTTERS WHEN GOING AT A CONSTANT SPEED. THIS STARTED AROUND 10K MILES AND THE DEALERSHIP HAS TRIED TO FIX IT THREE TIMES WITHOUT SUCCESS. FIRST TWO TIMES THEY REPLACED THE TORQUE CONVERTER AND THIRD TIME THEY REPLACED THE TRANSMISSIONS FLUID. THE TRUCK ALSO SHIFTS VERY HARD FROM FIRST GEAR TO SECOND GEAR WITH A HUGE JERKING MOTION AROUND 10 MPH. THIS IS VERY DANGEROUS WHEN DRIVING IN PARKING LOTS OR ANYWHERE NEAR PEDESTRIANS. FINALLY, WHEN COMPRESSING THE BRAKE AT 25MPH THE TRUCK JERKS VERY VIOLENTLY DOWN TO THE NEXT GEAR. THE TRANSMISSION IN THESE TRUCKS NEEDS TO BE RECALLED AND REPLACED SOON.

I HAVE A 2017 COLORADO Z71. I BOUGHT IT SPECIFICALLY SO THAT BOTH MY WIFE AND I COULD USE IT AS NECESSARY, (BEING OF QUITE SMALL STATURE SHE IS UNABLE TO DRIVE A FULL SIZE PICK UP) HOWEVER, DUE TO THE FOLLOWING ONGOING ISSUES SHE HAS YET TO AGREE TO DRIVE IT OUT OF CONCERN FOR HER SAFETY. IT PRESENTED WITH WHAT HAVE BECOME CHRONIC TRANSMISSION PROBLEMS IMMEDIATELY AFTER PURCHASE. I HAVE RETURNED IT TO THE DEALER MULTIPLE TIMES TO NO AVAIL. INITIALLY IT INTERMITTENTLY SHUDDERED TO THE POINT OF VIBRATING THE ENTIRE VEHICLE AS IF DRIVING OVER RUMBLE STRIPS WHILE DRIVING ON EITHER STREETS OR HIGHWAY. THEN IT BEGAN LUNGING FORWARD UNEXPECTEDLY AND UNCONTROLLABLY WHEN PRESUMABLY SHIFTING TO THE POINT WHICH FEELS LIKE HAVING BEEN REAR ENDED BY ANOTHER VEHICLE WHILE DRIVING ON BOTH STREETS AND IN PARKING LOTS. DURING THE SPAN OF MULTIPLE VISITS THE DEALER HAS REPLACED THE TORQUE CONVERTER, AS WELL AS REPLACING THE TRANSMISSION FLUID. DESPITE NO LONGER SHUDDERING, THE VEHICLE STILL LUNGES RANDOMLY. I WAS INFORMED BY THE SERVICE MANAGER DURING MY LATEST VISIT ABOUT THE LUNGING THAT THEY KNEW WHAT THE VEHICLE IS DOING, AND THAT THERE IS NO FIX FOR IT...WHICH IS ABSOLUTELY UNACCEPTABLE. I'M QUITE CONCERNED ABOUT MY VEHICLE LUNGING UNEXPECTEDLY AND UNCONTROLLABLY INTO A PEDESTRIAN OR ANOTHER VEHICLE.

TRANSMISSION SHUDDER. SEEMS COMMON AFTER 40,000 MILES ON THE MAJORITY OF 2017-19 COLORADOS. TRUCK WOULD VIBRATE LIKE DRIVING OVER A RUMBLE STRIP AROUND 55+ MPH AFTER TRANSMISSION FLUID WOULD WARM UP ABOVE 80 DEGREES F. SHOULD BE A RECALL BECAUSE I HAD TO GO THROUGH HOOPS TO GET THEM TO EVEN LOOK AT THE TRANSMISSION BECAUSE THEY THOUGHT IT WAS A TIRE OR WHEEL WEIGHT. SUPER INCONVENIENT AND TIME CONSUMING.

I GOT A CHECK ENGINE LIGHT WHILE AND ENGINE GOES INTO REDUCED POWER MODE. YOU CAN'T DRIVE IN REDUCED POWER MODE! I HAVE TO CLEAR IT TO MOVE THE TRUCK. I DID A SCAN WHICH SHOWED A P2138 CODE. BUT ITS JUST IN MEMORY AND THE DEALER WONT FIX IT UNLESS ITS AN ACTIVE CODE BUT CAN'T DRIVE TO THE DEALER IN REDUCED POWER MODE. ITS A CATCH 22

TRANSMISSION SHUDDER

MY TRUCK SHUDDERS HORRIBLY ON HIGHWAY AND IN TOWN. IT STARTED JUST BEFORE MY LAST SERVICE AT 33731 MILES. I MENTIONED IT TO SERVICE ADVISOR AND WAS TOLD WITHOUT A CODE AS OWNER I WOULD BE THE ONLY ONE THAT COULD TELL THIS. NOTHING WAS DONE. THE ISSUE IS IRRITATING I RESEARCHED AND FOUND OUT IT IS AN ISSUE WITH MANY COLORADOS AND GM VEHICLES WITH THE SAME TRANSMISSION. I WILL BE CHECKING WITH THE DEALERSHIP SERVICE AGAIN TO SEE WITH THE INFORMATION I HAVE DISCOVERED IF ANYTHING WILL BE DONE.

UPPER CONTROL ARM, RIGHT HAND SIDE, WENT BAD AND NEEDED REPLACEMENT IN UNDER 20,000 MILES. DETECTED WITH A CLUNKING NOISE, AND CONFIRMED WHEN I WENT IN FOR ALIGNMENT. IT WAS REPLACED BEFORE IT BROKE, BUT A BROKEN CONTROL ARM IS A MAJOR SAFETY RISK.

TRANSMISSION SHUTTERING AND JERKING. RECALL NEEDS TO BE DONE IMMEDIATELY.

EXPERIENCE TRANSMISSION SHUDDER WHILE DRIVING VEHICLE. COULD CAUSE ISSUE WHILE PASSING OTHER VEHICLES DUE TO LOSS OF POWER. THE AMOUNT OF MONEY THESE NEWER VEHICLES ARE CHARGING, TRANSMISSION SHIFTING SHOULD BE FLAWLESS. NOT SURE IF THIS IS GOING TO GET WORSE AND CAUSE AN ACCIDENT. COULD IT JUMP GEARS WHILE TRYING TO COME TO A STOP? THIS IS ONGOING AND NEEDS TO BE ADDRESSED AND A REMEDY BY THE MANUFACTURER SOON.

SHUDDER AND SLIPPING IN THE GEARS CAUSED BY BAD FLUID AND TORQUE CONVERTER.

GO TO TURN THE KEY OFF AND THE IGNITION WON'T TURN OFF ALL THE WAY, HAVE TO RESTART THE TRUCK A COUPLE OF TIMES TO EVEN GET THE KEY TO TURN OFF TO GET THE KEY OUT, ALSO GO TO START THE TRUCK AND SOMETIMES IT WON'T MOVE THE IGINITION

WHEN YOU START THE TRUCK IT SMELLS REALLY STRONG OF GAS WHEN RUNNING

HARD SHIFTING & SLIPPING OF THE TRANSMISSION STARTED AT ABOUT 10,000 MILES. DEALER UNABLE TO REPAIR EVEN THOUGH THEY TRIED 4 TIMES INCLUDING A REMANUFACTURED TRANSMISSION. NOT SURE WHAT TYPE OF DAMAGE IS OCCURRING TO THE TRANSMISSION WITH THIS HARD SHIFTING.

TL* THE CONTACT OWNS A 2017 CHEVROLET COLORADO. THE CONTACT STATED THAT WHEN DRIVING AT AN UNKNOWN SPEED, THE ENGINE HESITATED WITHOUT WARNING. THE VEHICLE WAS TAKEN TO THE STAR CHEVROLET DEALER (724-790-2046, LOCATED AT 5200 US-30 C, GREENSBURG, PA 15601) WHERE THE TRANSMISSION FLUID WAS REPLACED. THE FAILURE RECURRED AND THE SAME TECHNICIAN REPLACED THE TORT CONVERTER. THE FAILURE RECURRED AND WHEN THE VEHICLE WAS TAKEN BACK TO THE SAME DEALER, THE TECHNICIAN STATED THAT THE VEHICLE WAS PERFORMING AS DESIGNED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND STATED THAT THE ISSUE WOULD BE INVESTIGATED. THE CONTACT WAS NOT CALLED BACK. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 18,000. *JB

VEHICLE SHUDDERS/SHAKES WHEN ACCELERATING OR MAINTAINING SPEED. CAN BE LIGHT SHUDDER, LIKE DRIVING OVER A BUMPY ROAD. OR CAN BE ENOUGH TO MAKE EVERYTHING SITTING IN DASH TO SHAKE VIOLENTLY.

TL* THE CONTACT OWNS A 2017 CHEVROLET COLORADO. WHILE DRIVING LOW SPEEDS, THE STEERING WHEEL BECAME DIFFICULT TO TURN. THE CONTACT HAD TO JERK THE STEERING WHEEL TO GET IT TO OPERATE NORMALLY. IN ADDITION, THE BRAKE WARNING INDICATOR ILLUMINATED. THE "PLEASE CHECK POWER STEERING "AND "DRIVE SAFELY" MESSAGES WERE ALSO DISPLAYED. THE VEHICLE WAS TAKEN TO BARLEY AUTOMOTIVE (791 STE GENEVIEVE DR, GENEVIEVE, MO 63670, (573) 355-9633) WHERE IT WAS DETERMINED THAT THE VEHICLE WAS OPERATING AS DESIGNED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT CONTACTED. THE FAILURE MILEAGE WAS 19,000.

STEERING LOCKED WHEN TURNING INTO A PARKING LOT AND WOULD NOT STRAIGHTEN OUT

WHEN RUN IN HIGH HEAT, A VALVE IN THE AIR CONDITIONING SYSTEM FREEZES UP AND SHUTS DOWN THE SYSTEM. THE SYSTEM NEEDS TO BE TURNED OFF UNTIL THE VALVE UNTIL IT DEFROSTS BEFORE THE SYSTEM RESUMES TO OPERATE. I TOOK IT INTO THE DEALERSHIP AND WAS TOLD THAT IT IS A KNOWN PROBLEM AND THAT THE MANUFACTURER IS LOOKING INTO WAYS TO REPAIR IT AND WOULD NOTIFY ME. I WAS ALSO TOLD THAT THE SYSTEM IN MY VEHICLE IS ALSO USED IN OTHER MODELS AND AFFECTS THEM ALL. IT HAS BEEN 8 OVER MONTHS AND NOTHING HAS BEEN HEARD FROM THE DEALER. I SENT THEM A MESSAGE INQUIRING AND THEY HAVE NOT RESPONDED. I DON'T KNOW IF THIS QUALIFIES AS A SAFETY COMPLAINT THAT YOUR DEPARTMENT INVESTIGATES BUT NOT HAVING A WORKING A/C WHEN DRIVING ACROSS THE DESERT IN 120+ DEGREE HEAT IS NOT CONDUCIVE TO GOOD HEALTH. THANK YOU FOR YOUR TIME.

STEERING IS INTERMITTENT AT TIMES. THE STEERING WHEEL WILL NOT TURN SMOOTHLY, INSTEAD IT JUMPS IN 1-2" INCREMENTS. SEEMS TO RESET OR FIX ITSELF AFTER THE TRUCK IS TURNED OFF FOR A LITTLE WHILE.

TL* THE CONTACT OWNS A 2017 CHEVROLET COLORADO. WHILE DRIVING AT HIGH SPEEDS, THE VEHICLE STARTED TO VIOLENTLY VIBRATE. THE FAILURE ALSO OCCURRED WHEN ACCELERATING FROM A STOP. THE VEHICLE WAS TAKEN TO DYER CHEVROLET FORT PIERCE (4200 US HIGHWAY 1, FORT PIERCE, FL 34982, (772) 242-3116) MULTIPLE TIMES FOR THE FAILURE WHERE THE TRANSMISSION WAS SERVICED AND FLUSHED; HOWEVER, THE FAILURE RECURRED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND THE CONTACT RECEIVED A CASE NUMBER. THE FAILURE MILEAGE WAS 17,000.

SEPT 2018 HAVE NOTICED THAT TRUCK SEEMS TO VIBRATE, SHUDDER AT 50-60MPH. VIBRATION, SHUDDERING GOT WORSE, EVEN AT 25MPT. OCTOBER, I CONTACT SERVICE ADVISOR WHO BELIEVES MIGHT BE TORQUE CONVERTER NEED APPT TO VERIFY NOVEMBER FINALLY GOT APPT WITH SERVICE DEPT . THEY VERIFY IT IS TORQUE CONVERTOR AND ORDER PARTS. DECEMBER PARTS IN & TRUCK IN FOR 3 DAYS AS PARTS INSTALLED. TOLD THIS SHOULD SOLVE ISSUE, BUT CHEVROLET WORKING OF ANOTHER FIX FOR 1ST QUARTER OF 2019. TO DATE, I HAVE NOT NOTICED ANY ISSUES OF VIBRATION.DATE.

FUEL PUMP WELD CRACK, SERVICE 4WD MESSAGE DISPLAYED, CLUNKING IN REAR END ALL DISMISSED REPEATEDLY FROM DEALERSHIP I PURCHASED MY VEHICLE FROM. I BOUGHT THIS TRUCK NEW OFF THE LOT WHICH HAS BEEN IN THE SHOP IN EXCESS OF 10 TIMES FOR MULTIPLE ISSUES. THE 4X4 STARTED NOVEMBER 2017 I WAS TOLD IT WAS BECAUSE WE WERE HAVING ABNORMALLY COLD WEATHER AND IT WOULD COME OUT OF IT. IT HAS BEEN IN MULTIPLE TIMES SINCE THEN AND THEY WERE UNABLE TO DUPLICATE. CLUNKING IN REAR WAS DISMISSED AS NOTHING, COULD NOT DUPLICATE. I STARTED SMELLING BURNING PLASTIC, THEN WHEN STARTING MY VEHICLE IN THE MORNING THE EXHAUST SMELL WAS SO OVERPOWERING THAT IT WOULD GAG US. THE BURNING PLASTIC SMELL WAS INTERMITTENT WHILE DRIVING AND THAT WAS ONLY AFTER DRIVING THE TRUCK BETWEEN 2 TO 20 OR THE FULL DRIVE HOME AND SOMETIMES NOT AT ALL. I HAD BEEN NODDING OFF, GETTING MASSIVE HEADACHES AND SICK TO MY STOMACH WHILE DRIVING MY TRUCK, SO WAS MY DAUGHTER. NO MATTER WHAT THEY HAD MY TRUCK FOR, THEY COULD NOT DUPLICATE THE ISSUE AND I HAD A LOANER FOR A WEEK AT A TIME. I TOOK MY VEHICLE TO ANOTHER DEALERSHIP WHO JUST ENDED UP SEALING MY PICKUP BOX, REPLACING FUEL PUMP MODULE, INSTALLED A BODY PLUG PER A BULLETIN, PER BULLETIN APPLIED LUBRICANT TO BOTH REAR LEAF SPRINGS AND TORQUED LEAF SPRINGS TO SPECS. TRANSFER CASE CONTROL MODULE HAD A BULLETIN FOR WHICH MY DEALER STATED THEY PUT DIELECTRIC LUBRICANT. I WAS DRIVING A VEHICLE WITH MY CHILD IN IT WITH CARBON MONOXIDE POISONING US BASED ON THE SYMPTOMS WE WERE B

TL* THE CONTACT OWNS A 2017 CHEVROLET COLORADO. WHILE DRIVING 70 MPH, THE CONTACT'S DAUGHTER-IN-LAW PLUGGED IN HER CELL PHONE TO THE CHARGING UNIT. SHORTLY AFTER, THE VEHICLE DECELERATED, YET THE RPMS INCREASED WITHOUT WARNING. THE VEHICLE WAS TOWED TO KREIGERS CHEVROLET BUICK (2113 11TH ST, DEWITT, IA 52742, (563) 659-3225) TO BE DIAGNOSED, BUT NO FAILURE CODES COULD BE LOCATED.

THE FAILURE MILEAGE WAS 11,300. *TT CONSUMER STATED FIRST TIME IT SHUT DOWN CHANGED OUT TRANS CONTROL MODULE, SECOND TIME STOPPED AT THE STOP SIGN BY WOULD NOT MOVE, DEALER THOUGHT IT WAS THE TRANSMISSION. SO AFTER MANY TRIES DEALER REPLACED IT. AFTER IT WAS REPLACED IT FAILED TWO MORE TIMES. CONSUMER THEN PULLED TO THE ROAD AND THE DOOR LOCKS KEPT LOCKING AND UNLOCKING. THIS IS TWO MONTHS IN.*JB

MY COMPLAINT IS ALL THE VEHICLES ON THE ROAD RUNNING WITH NO LIGHTS ON. THIS IS HAPPENING MORE AND MORE EVEN IN ALMOST DARK TIMES OF THE DAY. TODAY I DROVE AN HOUR EACH WAY ON I-696 FROM HOWELL TO I-75 AND SAW AT LEAST 20 VEHICLES WITH NO LIGHTS IN HEAVY FOG AND RAIN. I LEAVE MY HOME AT DAWN FOR WORK EVERY DAY AND HAVE ALMOST PULLED OUT IN FRONT OF TRAFFIC WITH NO LIGHTS ON. VEHICLES BLEND RIGHT INTO THE SNOW BACKGROUND WITHOUT RUNNING LIGHTS. PLEASE MAKE LIGHTS MANDATORY 24/7 SO ACCIDENTS AND INJURIES/DEATHS CAN BE AVOIDED.

WHILE ACCELERATING ON THE FREEWAY FROM APPROXIMATELY 65MPH, THE STABILITY CONTROL SYSTEM ENGAGED AND TOOK CONTROL OF THE ACCELERATION OF THE VEHICLE. ROADS WERE DRY WITHOUT ICE, SNOW OR RAIN. THE STABILITY CONTROL REDUCED POWER UNTIL THE ENGINE DIED EVEN WHILE PRESSING THE ACCELERATOR TO THE FLOOR. THE ENGINE WOULD NOT RESTART FOR APPROXIMATELY 5 MINUTES. THIS OCCURRED 3 TIMES ON DIFFERENT INTERSTATES ON A TRIP. WE WERE FORCED TO CAREFULLY MOVE TO THE RIGHT SHOULDER WHILE OUR VEHICLE WAS SLOWING UNTIL THE ENGINE DIED. MY WIFE AND I WERE LUCKY WE WERE NOT INVOLVED IN A SERIOUS ACCIDENT. ONSTAR NOTIFICATIONS SENT THE FOLLOWING IN AN EMAIL, "AN ISSUE WITH THE ENGINE AND TRANSMISSION SYSTEM IN YOUR 2017 CHEVROLET COLORADO HAS BEEN DETECTED. PLEASE SERVICE YOUR VEHICLE WITHIN 7 DAYS."

TL* THE CONTACT OWNS A 2017 CHEVROLET COLORADO. WHILE DRIVING VARIOUS SPEEDS, THE CONTACT SMELLED AN ABNORMAL ODOR COMING FROM THE AIR VENTS. THE VEHICLE WAS TAKEN TO HURD AUTO MALL (1705 HARTFORD AVE, JOHNSTON, RI, 401-372- 3051) TO BE DIAGNOSED, BUT THE FAILURE COULD NOT BE DUPLICATED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND PROVIDED CASE NUMBER: 9-4995645432. THE FAILURE MILEAGE WAS APPROXIMATELY 8,930.

AT SPEEDS 45 MPH TRANSMISSION MAKES A LOAD THUMBING SOUND AND START SWITCHING BACK AND FORTH FOR GEAR. AT SPEEDS 60 UP TO 70 MPH A SHUDDERING STARTS MOSTLY UP GRADES AND DOWN GRADES. FROM REVIEW THERE IS A BULLETIN GM 16-NA-175. FROM WHAT I READ THIS DOESN'T FIX THE PROBLEM. THERE ARE NUMEROUS OF COMPLAINTS.

TRUCK BOGS DOWN, LOOSES POWER WHEN TAKING OFF FROM A STOP. FRONT TIRES FEEL LIKE THEY ARE SKIPPING EVEN THOUGH TRUCK IS IN 2 WHEEL DRIVE ESPECIALLY UP HILL. ONCE TRUCK GETS GOING IT RUMBLES AND VIBRATES SO MUCH IT BOTHERS YOUR EARS, CONSTANTLY LOOSING POWER AND SPEED AS YOUR DRIVING. WAS TOLD IT WAS THE TORQUE CONVERTER AND IT WAS REPLACED. TRUCK CONTINUED TO HAVE SAME ISSUE. TRUCK THEN 'BLEW UP' (DEALERSHIP WORDS) WHILE I WAS DRIVING 75 MPH DOWN THE HIGHWAY. DEALERSHIP STATED 'IT WAS LIKE YOUR TRUCK WENT INTO LOW GEAR WHILE YOU WERE DRIVING AND IT SHOULD NEVER BE ABLE TO DO THAT'. HAD FLUID FLUSH AND REPLACED AGAIN AND RUMBLING AND POWER LOSE STILL OCCURRING.

TL* THE CONTACT OWNS A 2017 CHEVROLET COLORADO. WHILE DRIVING HIGHWAY SPEEDS, THE CONTACT NOTICED THAT THE TACHOMETER FLUCTUATED AND THE TRANSMISSION SHUDDERED. THE VEHICLE WAS TAKEN TO AN UNKNOWN DEALER WHERE IT WAS DIAGNOSED THAT THE TRANSMISSION TORQUE CONVERTER FAILED. THE DEALER REPLACED THE TORQUE CONVERTER AND THE TRANSMISSION WAS FLUSHED. THE DEALER ALSO REPROGRAMMED THE TRANSMISSION COMPUTER. THE MANUFACTURER WAS CONTACTED AND PROVIDED CASE NUMBER: 9-4982753540. THE MANUFACTURER ISSUED TECHNICAL SERVICE BULLETIN NUMBER: 4942742 PIE0405C (ENGINEERING INFORMATION TORQUE CONVERTER SHUDDER). THE APPROXIMATE FAILURE MILEAGE WAS 13,500. *TT CONSUMER STATED TORQUE CONVERTER HAD WRONG TRANSMISSION FLUID FROM FACTORY.*JB

AT 21000 MILES FELT LIKE DRIVING OVER RUMBLE STRIPS AND TACH WOULD MOVE IN CRUISE. DEALER FLUSHED TRANS. 4 MONTHS LATER AT 29000 MILES SAME PROBLEM BUT NOW SHIFTING HARD NOTICED DURING ACCELERATION AND DECELERATION. CHANGED OUT CONVERTER AND FLUSH. NOW 3 MONTHS LATER AND ONLY 2500 MILES LATER IT HAS STARTED ALL OVER AGAIN. SO BACK TO THE DEALER I WILL GO. AM STARTING TO REGRET BUYING A CHEVY INSTEAD OF STAYING WITH MY TRUSTY FORD

TRANSMISSION SHUDDER. FELLS LIKE DRIVING OVER RUMBLE STRIPS. GM KNOWS OF THIS ISSUE BUT KEEPS PUTTING THESE 8 SPEED TRANSMISSIONS ON THE ROAD.

WHEN AUTOMATIC TRANSMISSION DOWNSHIFTS INTO 1ST GEAR COMING TO A STOP, IT LUNGES FORWARD. IF WHEN NOSING INTO A PARKING SPACE WITH ANY KIND OF POLE OR VEHICLE DIRECTLY IN FRONT OF MY TRUCK, NOT LEAVING ENOUGH SPACE MY TRUCK WOULD HIT WHATEVER. WHEN DRIVING SLOWLY WITH MY 8 SPEED AUTOMATIC TRANSMISSION SOMETIMES IT RATTLES AS IF I AM ON A RUMBLE STRIP AND SOMETIMES IT JUST CLUNKS OR THUDS. THIS AND OTHER SHIFT ISSUES MAKE ME EVEN MORE HYPER VIGILANT WHEN DRIVING. 6 MONTHS AFTER I PURCHASED MY BRAND NEW 2017 COLORADO, DURING A SPELL OF NEGATIVE DEGREE WEATHER I LOST THE FOLLOWING: MY CRUISE CONTROL, TRACTION CONTROL, FOUR-WHEEL DRIVE; MY ENGINE LIGHT CAME, OIL LIGHT ALL LIGHTS CAME ON AND MY RADIO STOPPED WORKING. I WAS TOLD BY MY CHEVY DEALER THAT THIS WAS NORMAL IN COLD WEATHER. NEXT, I WAS INFORMED IT MUST BE BECAUSE I WASHED MY VEHICLE THE DAY BEFORE. THIS WENT ON FOR A FEW MONTHS, WITH ME SHOWING THEM VIDEOS AND THEM TELLING ME THEY COULD NOT DUPLICATE THE ISSUE. OCTOBER OF 2018 THEY REPLACED MY RADIO BECAUSE EVIDENTLY THE RADIO HAD A BULLETIN THAT SHOWED ALL OF THE THINGS I HAD COMPLAINED ABOUT. I WANT TO SAY THIS HAPPENED IN EXCESS OF 10 OR MORE TIMES. DRIVING TO MY MOTHERS ONE EVENING IN THE DARK MY DASH LIGHTS WERE NOT DIMMING CORRECTLY AND THEN WENT OUT. AS I GOT TO A FOUR WAY INTERSECTION WITH CARS COMING THEY CAME ON SO BRIGHTLY I ALMOST GOT IN AN ACCIDENT WHICH PROMPTED ME TO MAKE AN APPOINTMENT AND I WASN'T WILLING TO HEAR SILLY EXCUSES.

POWER STEERING WOULD GO OUT AT ANT TIME AND THEN IT WOULD START WORKING AT DIFFERENT TIMES.WOULD HAVE AN AUDIBLE ALARM SERVICE POWER STEERING WOULD COME ON THE DISPLAY AND MY ABS AND BRAKE LIGHT WOULD TURN ON.ALMOST WRECKED ON 3 DIFFERENT OCCASIONS BECAUSE OF THE LOSS AND THEN WORKING OF THE STEERING

DIRT ROAD 11PM AT NIGHT, TURNED LEFT TO GET OUT OF THE UNEVEN GROUND ABOUT 5 MPH, SIDE CURTAIN WENT OFF, SEATBELT PRETENSIONERS DEPLOYED

THE AIR CONDITIONER PERIODICALLY AND AT RANDOM WILL FREEZE UP ON TRIPS OVER 1/2 HOUR. I HAVE TAKEN IT TO THE DEALER TWICE. ONCE THEY COULD DUPLICATE THE PROBLEM AND REPLACED THE EVAPORATOR TEMPERATURE SENSOR. BUT I STILL HAVE THE PROBLEM. THIS LAST TIME THEY KEPT THE VEHICLE TWO DAYS AND COULDN'T DUPLICATE THE PROBLEM. I HAVE MEASURED THE VENT AIR TEMPERATURE AS LOW AS 35 DEGREES (THE TEMP SENSOR SHOULD NOT ALLOW THIS) AND HAVE ALSO MEASURED THE TEMP AT 40 DEGREES F AT WHICH TIME IT STARTED TO FREEZE UP. WHEN THIS OCCURS, THE VOLUME OF AIRFLOW DROPS, THE VENT AIR TEMPERATURE STARTS TO CLIMB AND IF I STOP AND OPEN THE HOOD I WILL SEE ICE ON THE EVAPORATOR LINE. THE PROBLEM HAS OCCURRED ON THE HIGHWAY ON 2 TO 3 HOUR TRIPS BUT ALSO HAS OCCURRED ON A 1 HOUR TRIP AT 50 MPH AND ALSO A 1/2 HOUR TRIP IN CITY (STOP AND GO) TRAFFIC. THE AC COMPRESSOR DOES NOT APPEAR TO EVER TURN OFF, UNLESS I PUSH THE BUTTON TO TURN OFF THE AC. THE DEALER CANNOT FIX. GM ENGINEERS ARE STUDYING BUT DON'T HAVE A SOLUTION.

MAKING A RIGHT HAND TURN ONTO OUR ROAD THE STEERING WHEEL LOCKED UP. I WAS UNABLE TO CONTROL THE TRUCK OTHER THAN BRAKING. AFTER SLAMMING ON THE BRAKES THE STEERING RESUMED.

I HAVE HAD REPEATED ISSUES WITH THE TRANSMISSION AND THE TRANSMISSION WILL NOT SHIFT OUT OF 5TH GEAR WHEN IN TOW MODE AND WHEN TOWING LOAD UNDER SPECIFICATIONS. I HAVE STARTED THE LEMON LAW PROCESS BUT THE MANUFACTURER HAS DENIED MY CLAIM AS OF TODAY.

AIR CONDITIONING IS INTERMITTENT/BLOWS WARM/EMITS FOG FROM VENTS. THE DEALER SAYS NO FIX AVAILABLE YET CITES PER DOC ID:5125499.SAYS ENGINEERING IS STUDYING PROBLEM. MINE STOPS WORKING-BLOWS WARM WITH IN 1/2 HOUR. ALSO IN STOP/GO TRAFFIC THE TRANSMISSION DOWNSHIFTS ABRUPTLY AND CAUSES TRUCK TO ACCELERATE FORWARD-HAVE TO APPLY BRAKES HARD TO AVOID COLLISION. DEALER SAYS CAN NOT REPEAT BUT SHIFTING IS CONSISTENTLY ABRUPT AND I HAVE ASKED ABOUT SOFTWARE UPDATES TO ALLIEVIATE THIS SAFTY CONCERN TO NO AVAIL

THE VEHICLE HAS A SHUDDER IN THE TRANSMISSION UNDER LIGHT THROTTLE ACCELERATION BETWEEN ABOUT 50 AND 80 MPH ON THE HIGHWAY. IT FEELS AS IF I'M DRIVING OVER RUMBLE STRIPS ON THE ROAD FOR ABOUT A SECOND. THEN IT WILL STOP FOR A SECOND OR TWO, AND THEN SHAKE AGAIN FOR A SECOND. WITHOUT THROTTLE, NO SHAKING OCCURS. THIS HAS BEEN OCCURRING FOR ABOUT TWO WEEKS, OR PERHAPS THE LAST 500 MILES. IT MIGHT BE DESCRIBED BY BULLETIN 18-NA-177.

TL* THE CONTACT OWNS A 2017 CHEVROLET COLORADO. WHILE DRIVING AT AN UNKNOWN SPEED, THE VEHICLE ACCELERATED AND JERKED. ADDITIONALLY, THE BRAKES WERE APPLIED, BUT FAILED TO RESPOND AND THE BRAKE PEDAL TRAVELED TO THE FLOORBOARD. IN ADDITION, THE CONTACT HEARD AN ABNORMAL SCRATCHING NOISE. THERE WERE NO WARNING INDICATORS ILLUMINATED. THE VEHICLE WAS TAKEN SEVERAL TIMES TO GILROY CHEVROLET (6720 AUTOMALL CT, GILROY, CA 95020, 408-842-9301), BUT THEY WERE UNABLE TO DUPLICATE THE BRAKE FAILURE. THE DEALER DIAGNOSED THE ACCELERATION FAILURE AS THE FOUR WHEEL DRIVE BEING ENGAGED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED AND PROVIDED CASE NUMBER: 8-4000-730943. NO FURTHER ASSISTANCE WAS PROVIDED. THE FAILURE MILEAGE WAS APPROXIMATELY 17,759.

EXPERIENCING ELECTRICAL PROBLEMS CAUSING STARTING ISSUES, WHILE DRIVING FAILURES IN DASH INDICATOR LIGHS, SPEEDOMETER , TACHOMETER, SHIFT CONTROL INDICATOR LIGHTS, AND TRANSMISSION CONTROL. LOSS OF POWER TO THE POINT TRUCK ALMOST COMES TO A STOP AND THEN SURGES, TWICE IT HAS ACCELERATED TRAVELING UP TO 50FT ESTIMATED.

8 SPEED AUTOMATIC TRANSMISSION - ROUGH SHIFTING, USUALLY WHEN DRIVING BETWEEN 40 AND 60 MILES PER HOUR. TRUCK INTERMITTENTLY FEELS LIKE IT IS RIDING OVER RUMBLE STRIPS. TRANSMISSION SEEMS TO BE HUNTING. POSSIBLE ISSUE WITH TORQUE CONVERTER.

WHEN AUTOMATIC TRANSMISSION DOWNSHIFTS INTO 1ST GEAR COMING TO A STOP, IT DOES SO HARSHLY AND LUNGES FORWARD. WHEN NOSING INTO A PARKING SPACE WITH A CONCRETE WALL AT THE FRONT OF THE PARKING SPACE, IF I HAD NOT ALLOWED ENOUGH SPACE FOR THE LUNGE, THE VEHICLE WOULD HAVE IMPACTED THE WALL . THIS CONDITION, ALONG WITH OTHER TRANSMISSION SHIFT IRREGULARITIES, HAPPENS PERIODICALLY AND I MUST REMAIN AWARE, ESPECIALLY COMING TO A STOP NEAR A CROSS WALK.

WHEN DRIVING AT LOW SPEEDS MY 8 SPEED AUTO TRANSMISSION - CLUNKS OR THUDS - SPECIALLY FROM 1ST - 2ND - ITS SOUNDS LIKE A BANG - TOOK IT TO DEALER - SAID CHEVY KNOWS ABOUT IT - BUT THERE IS NO FIX YET.....GREAT!

8 SPEED TRANSMISSION HAS HARD SHIFT WHEN AT LOW SPEEDS AND WHEN GOING INTO REVERSE
