2017 Chevrolet Colorado Power Train

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.

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.

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.

TRANSMISSION SHUDDER

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.

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.

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.

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.

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.

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

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.

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.

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 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

8-SPEED AUTOMATIC TRANSMISSION IN INDECISIVE WHEN IT COMES TO SHIFTING BETWEEN LOWER GEARS WHILE DRIVING. TRANSMISSION MAKING CLUNKING "THUD" SOUND WHEN SHIFTING OUT OF PARK AND INTO REVERSE. GEAR HUNTING EXPERIENCED AT LOWER SPEEDS AND GEARS WHILE VEHICLE ATTEMPTS SHIFTING.

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 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.

AFTER ABOUT 600-700 MILES ON NEW VEHICLE, AFTER TRUCK SITS OVERNIGHT WHEN FIRST STARTED YOU COULD FEEL WHAT SEEMS TO BE THE THE TORQUE CONVERTER WAS ENGAGING AS IT THE TRANSMISSION HAD LOST PRESSURE. THEN WHILE DRIVING ANYWHERE BETWEEN 40-65MPH CONVERTER SEEM TO BE UNLOCKING AND LOCKING WHICH CAUSE A VERY BAD SHUTTER AS IF YOU WERE DRIVING OVER BRICKS, AND THEN WHEN COMING TO A STOP THE TRANSMISSION DOWN SHIFTED INTO 1ST GEAR VERY VERY HARD, WHICH IS HARD ON THE DRIVE LINE. TOOK BACK TO DEALER THEY KEEP IT 3 DAYS AND FLUSHED TRANS FLUID WITH A NEW SPECIAL FLUID. THE SHUTTERING HAS STOPPED BUT THE OTHER 2 PROBLEMS REMAIN, SO I'M THINKING NOW THEY'LL HAVE TO CHANGE THE CONVERTER OUT.

THE PROBLEM WITH MY CHEVROLET COLORADO 2017 TRUCK STARTED WITH WHEN THE NEW TRUCK BARLEY HAD UNDER 200 MILES ON ITS ODOMETER. THE ISSUE IS THE TRUCK STARTS TO VIBRATED AT A SPEED OF 50-55 MPH LIKE IF YOU ARE GOING THRU SPEED BUMPS AND THE NOISE STOPS WHEN YOU GO OVER 60 MILES PER HOUR. I HAVE DONE A SIMPLE 20 MINUTE RESERCH AND HAVE FOUND OUT THAT THERE ARE OTHER INDIVIDUALS THAT HAVE HAD THE SAME ISSUE WITH THEIR SAME YEAR COLORADO TRUCK'S. I TOOK MY TRUCK TO THE DEALERSHIP WHERE I BOUGHT THE TRUCK. THEY KNEW EXACTLY WHAT THE ISSUE WAS. THEY ARE IN THE PROCESS OF REPLACING THE TORQUE CONVERTER. LOOKS LIKE A MAJOR CONCERN TO ME.

AT 1400 MILES TRUCK STARTED A HEAVY PULSATING VIBRATION BETWEEN 50 AND 55 MILES PER HOUR. TOOK IT TO MYRTLE BEACH CHEVROLET WHERE THEY BALANCED THE TIRES. IT DID NOT FIX THE TRUCK. STILL VIBRATING NOW STARTING AT 20 MILES PER HOUR. SEVERE PULSATING VIBRATION AT 55 MILES PER HOUR. GOING BACK TO THE SHOP NEXT WEEK
