2017 Chevrolet Colorado

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

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.

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.
