2015 CHEVROLET COLORADO Complaints

PURCHASED 2015 COLORADO IN AUGUST. WHILE DRIVING IT I HAVE NOTICED THERE IS A PROBLEM WITH THE TRANSMISSION AND ENGINE SYNCHRONIZATION BETWEEN DOWN SHIFTING AND MAINTAINING PROPER RPM'S. WHEN DRIVING A STEADY SPEED IN TRAFFIC AND YOU NEED TO SPEED UP A LITTLE THE TRANSMISSION DOES NOT DOWN SHIFT. WHEN YOU GIVE IT GAS TO SPEED UP THE ENGINE THE RPMS ARE TO LOW AND THE ENGINE BUCKS AND IS LUGGING VERY BADLY. YOU ARE AT A POINT IT FEELS LIKE IT WILL STALL. THIS LUGGING HAS TO BE BAD FOR ENGINE. IF YOU PRESS DOWN HARDER ON THE ACCELERATOR THE TRANSMISSION WILL DOWN SHIFT SUDDENLY AND THE TRUCK WILL SURGE FORWARD QUICKLY. I HAVE ALMOST RUN INTO THE REAR OF VEHICLES WHILE IN TRAFFIC AND TRYING TO MAINTAIN FLOW SPEED.

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.

RETURNING TO WORK AFTER LUNCH BREAK. POWER STEERING FAILS AT ABOUT 45 MPH. 3RD TIME THAT THIS HAS HAPPENED. TOOK IT TO DEALER THE FIRST TIME AND WAS TOLD PROBLEM WAS SOLVED. TURNING TRUCK OFF AND ON AGAIN TEMPORARILY RESOLVES THE PROBLEM. TOOK TO DEALER AGAIN TODAY AND WAS TOLD THEY NEED TO ORDER MORE PARTS. HAVE FOUND MANY OTHER INSTANCES OF THIS TRUCK HAVING SIMILAR ISSUES ONLINE.

EXPERIENCED SUDDEN LOSS OF EPS(POWER STEERING) AFTER @ 30 MINUTES OF DRIVING: SYMPTOMS: SUDDEN LOSS OF POWER STEERING ALERT MESSAGE: SERVICE POWER STEERING DRIVE WITH CARE STABILITRACK AND TRACTION CONTROL DASH LIGHTS ON BACKUP CAMERA OK BUT NO GUIDE LINES MESSAGE ON SCREEN: VEHICLE GUIDING LINES UNAVAILABLE CODE SCANNER/READER SHOWS NO CODES. AFTER ENGINE RE-START: SERVICE STABILITRACK MESSAGE APPEARS FOR A BRIEF PERIOD, AGAIN, NO CODES. POWER STEERING WILL BE FINE AGAIN FOR A WHILE. PROBLEM REPEATED AFTER ANOTHER 30 MINUTE DRIVING. AGAIN, RESTART CLEARED THE PROBLEM. SEVERAL RECALLS FOR SIMILAR PROBLEM WITH GM VEHICLES: NHTSA CAMPAIGN'S: 14V719000, 14V395000 & 14V153000. NOTHING FOR COLORADO.

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.

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.

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

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.

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.
