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.

MY 2015 COLORADO Z71IS EXPERIENCING MODERATE TO SEVERE HESITATION CONCERNS. IT'S PROGRESSIVELY GETTING WORSE. I FIRST BROUGHT IT BACK TO THE DEALERSHIP TO HAVE IT CHECKED OUT AROUND1000 MILES, 6000 AND NOW 20000. EACH TIME THEY CLAIMED THEY CAN'T DO ANYTHING BECAUSE THE DIAGNOSTICS REVEAL NO TROUBLE CODES, ALTHOUGH, PER AFOREMENTIONED BULLETIN, THERE'S PROOF THAT A PROBLEM EXISTS. I INQUIRED IF IT COULD BE A MECHANICAL ISSUE, BUT THEY REFUSED TO BECAUSE NO DIAGNOSTICS PRODUCED NO CODES/PROOF.
HAD DENT REPAIRED ON DRIVERS FENDER, PICKED UP TRUCK FROM DEALER, DROVE 4 MILES HOME TO PUT IN GARAGE. NEXT MORNING AT 5:30 AM DISCOVERED TRUCK FIRE IN GARAGE DUE TO ELECTRICAL WIRING HARNESSES. EXTENSIVE DAMAGE TO GARAGE AND GARAGE FLOOR. EXTENSIVE DAMAGE TO TRUCK'S ELECTRICAL AND ENGINE AREA. DEALER TOLD ME IT IS A GM PROBLEM. NOW DEALING WITH GM LEGAL DEPT. BUT THIS COULD BE A MAJOR PROBLEM WITH ALL 2015/2016 TRUCKS, NO WARNING WHAT SO EVER PRIOR TO INCIDENT. VEHICLE IS A 2015 COLORADO NOT 1 YEAR OLD WITH 8300 MILES.
THREE SERVICE CALLS TO FIX WARNING LIGHT CHECK AIR BAG. ONE TO REPLACE PASSENGER SIDE ABOVE DOOR AIR BAG TWO TO FIX THE AIRBAG CONNECTER ON TWO DRIVER SIDE AIR BAGS. THIS STARTED IN OCTOBER 2015 AND LAST ONE WAS MAY 2016. IS THIS A ISSUE WITH THIS VEHICLE? WHY SO MANY AIRBAG PROBLEMS IN A SHORT PERIOD OF TIME.
TL* THE CONTACT OWNS A 2015 CHEVROLET COLORADO. ON SEVERAL OCCASIONS WHILE ATTEMPTING TO ACCELERATE IN TRAFFIC, THE ACCELERATOR PEDAL WAS DEPRESSED BUT THE VEHICLE FAILED TO RESPOND. AFTER WAITING FOR SEVERAL MINUTES, THE ACCELERATOR PEDAL WAS DEPRESSED AGAIN AND THE VEHICLE RESPONDED AS INTENDED. THE VEHICLE WAS TAKEN TO THE DEALER TO BE DIAGNOSED. THE MECHANIC WAS UNABLE TO DUPLICATE THE FAILURE. THE CONTACT STATED THAT THE FAILURE RECURRED SEVERAL TIMES. THE MANUFACTURER WAS NOT NOTIFIED. THE APPROXIMATE FAILURE MILEAGE WAS 30,000. UPDATED 06/29/16*LJ UPDATED 06/30/16.*JB
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
TRUCK HAS 11K MILES. WHEN BREAKING AT LOW SPEEDS, I GET A LOT OF BREAK SQUEAL. THIS HAPPENS DRIVING FORWARD OR IN REVERSE. ALSO, WHEN DRIVING THE TRUCK HAS A HARD TIME SHIFTING AND MAKES A RATTLING/PINGING NOISE WHEN IT IS TRYING TO FIND THE CORRECT GEAR. THIS HAPPENS SPORADICALLY WHEN DRIVING SLOW, FAST, UPHILL, AND MOSTLY OCCURS DURING ACCELERATION. THE SHIFTING ISSUE HAPPENS ON THE FREEWAY AS WELL AS CITY STREETS.
WHEN I SLOW DOWN OR COME TO A STOP AT A RED LIGHT . THE TRUCK STARTS STALLING AND DOESN'T WANT TO GO UNLESS I STOMP ON THE GAS . I HAVE TAKEN IT TWICE TO A CHEVROLET DEALER NEAR WHERE I LIVE. FIRST TIME THEY SAID THEY HAD TO DO SOMETHING TO THE COMPUTER . SECOND TIME THEY SAID NOTHING WAS WRONG AND I DIDN'T EVEN GET ANY PAPERWORK TO SHOW I HAD TAKEN IT TO THEM . IT IS STILL DOING IT . [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR
POWERING STEERING FAILED WHILE DRIVING (STRAIGHT) ON A CITY STREET AT APPROXIMATELY 30 MPH. SEVERAL WARNING LIGHTS CAME ON. NOT DRIVABLE EXCEPT A VERY SHORT DISTANCE. FORTUNATELY FAILURE HAPPENED VERY NEAR THE CHEVROLET DEALER AND I WAS ABLE TO DRIVE IT THERE. THIS MODEL IS SUBJECT TO A RECALL (GM RECALL 15595) HOWEVER LOCAL DEALER WAS TOTALLY UNPREPARED FOR SERVICING THE RECALL. I HAD THE TRUCK TO THE DEALER BY NOON ON APRIL 1; IT IS NOW APRIL 12 AND DEALER CANNOT TELL ME WHEN PARTS WILL ARRIVE AND/OR WHEN THE TRUCK WILL BE REPAIRED. NEITHER GM OR THE DEALER HAS VOLUNTEERED TO PAY THE COST OF THE RENTAL CAR THE DEALER PROVIDED FOR A FEE, DESPITE GM'S PLEDGE TO REMEDY THE CONDITION "WITHOUT CHARGE AND WITHIN A REASONABLE TIME."
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.
TL* THE CONTACT OWNED A 2015 CHEVROLET COLORADO. WHILE DRIVING APPROXIMATELY 70 MPH, THE VEHICLE INDEPENDENTLY LOST POWER AND AN UNKNOWN WARNING LIGHT ILLUMINATED. IN ADDITION, THE CONTACT NOTICED A BURNING ODOR INSIDE THE VEHICLE AND THE REAR OF THE VEHICLE CAUGHT ON FIRE. THE EMERGENCY BRAKE HAD TO BE APPLIED TO STOP THE VEHICLE. THE FIRE DEPARTMENT EXTINGUISHED THE FIRE. A FIRE REPORT WAS FILED AND NO INJURIES WERE REPORTED. THE VEHICLE WAS DESTROYED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 40,000. THE VIN WAS UNAVAILABLE.
TURN TURNS OFF - TRUCK IDLES LOW AND FEELS LIKE IT IS GOING TO STALL WHEN IN TRAFFIC ON THE FREEWAY AND AT A RED LIGHTS.- I WAS SITTING AT A RED LIGHT AND WHEN IT TURNED GREEN AND I PUSHED THE GAS PEDDLE IT DID NOT MOVE. IT HAD TURNED OFF. I PUT IT IN PARK AND WAS ABLE TO RESTART IT BUT AT LEAST 2 TIMES A DAY I HAVE TO PUT IT IN PARK AND PUSH THE GAS WHILE WAITING AT A RED LIGHT SO IT DOESN'T TURN OFF.
THREE DAYS AFTER PURCHASING THE TRUCK THE DASH DROP ON THE LEFT DRIVERS SIDE AND YOU CAN SEE THE SPEAKER THROUGH THE DASH. THE TRUCK WAS IN MOTION WHEN THIS HAPPEN. BEFORE WE COULD TAKE IT IN FOR REPAIRS? THE INTERIOR LIGHTS WERE COMING ON AND OFF; DOOR ALARM GOING OFF; DOOR LOCKS MOVING UP AND DOWN WHEN THE TRUCK WAS IN MOTION. STOP SEVERAL TIMES TO TRY AND SECURS BACK RIGHT 1/2 DOOR! IT WOULD NOT SECURE IN THE BOTTOM STICKER! AFTER THE REPAIRS WERE MADE? WE NOTICE THAT WE DROVE THE TRUCK ALL THE HOME AND THE BACK RIGHT 1/2 DOOR WAS NOT SECURE IN THE STRIKER! NO ALARMS WENT OFF! NO MATTER HOW HARD YOU SHUT THE DOOR? IT IS STILL HARD TO SECURE INTO THE BOTTOM STRIKER! NO ALARM WILL SOUND TO LET US KNOW THAT THIS DOOR IS STILL OPEN! ON 01/25/2016 I REPORTED A BUZZING COMING FROM BEHIND THE RADIO! WE SHUT ALL SATELLITE ELECTRONICS OFF! YOU CAN STILL HER A BUZZING COMING FROM THE RADIO IF THE TRUCK IS MOVING OR NOT, ENGINE RUNNING OR TURNED OFF; DOORS OPEN OR CLOSE! THE BUZZING IS NOT CONSENTIN AT THIS TIME; BUT IT IS STILL HAPPENING. I REPORTED IT TO THE DEALSHIP AND IT HAS NOT BEEN REPAIRED AS OF THIS DATE!
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.
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
WHEN DRIVING AT LOW SPEEDS, IT FEELS LIKE THE TRANSMISSION IS IN THE WRONG GEAR, BECAUSE WHEN YOU NEED A FAST ACCELERATION, THE CAR BUCKS AND ALMOST FEELS LIKE IT'S GOING TO STALL. IT SEEMS LIKE IT IS SEARCHING FOR THE RIGHT GEAR AND THEREFORE IT TAKES TIME TO REACT. I HAVE BEEN ON A FEW CLOSE CALLS, ALMOST GOT INTO AN ACCIDENT A COUPLE OF TIMES BECAUSE OF THIS BUCKING AND DELAY ON REACTING WHEN YOU NEED TO GET THE POWER FROM THE ENGINE.
ENGINE STALLS INTERMITTENTLY WHEN BEGINNING TO ACCELERATE FROM RED LIGHT/STOP SIGN. STALLS OCCURRED WITHIN 1 MILE DISTANCE FROM WHERE VEHICLE WAS STARTED. FIRST STALL WAS AT RED LIGHT MOVING FORWARD LIGHTLY. SIFTED THE VEHICLE TO PARK, TURNED KEY, VEHICLE TURNED OVER AND WAS ABLE TO DRIVE ONCE PUT IN PARK. THE VEHICLE WAS IMMEDIATELY TAKEN TO THE CHEVY SERVICE CENTER. THE SERVICE ADVISOR WAS ABLE TO READ AN ERROR CODE P0506 EVEN THOUGH THE CHECK ENGINE LIGHT WAS NOT ILLUMINATED. CHEVY COULD NOT SCHEDULE AN APPOINTMENT FOR THE VEHICLE UNTIL 5 DAYS LATER; THE ERROR HAD CLEARED AND THEY WERE UNABLE TO DUPLICATE THE PROBLEM. SERVICE DEPARTMENT DECLARED VEHICLE SAFE TO DRIVE AS IT THE ISSUE COULDN'T BE DUPLICATED. ENGINE STALLED A SECOND TIME WHEN BEGINNING TO CROSS ROAD AT A TWO-WAY STOP WITH ONCOMING TRAFFIC. SHIFTED VEHICLE TO PARK, TURNED TRUCK BACK ON, SHIFTED TO DRIVE AND WAS ABLE TO MOVE FROM INTERSECTION WITHOUT BEING HIT.. THE COLORADO WAS TAKEN TO THE DEALERSHIP A FEW HOURS LATER AND THE ERROR CODE HAD CLEARED ALREADY. SERVICE ADVISOR STATED THE CAR WAS SAFE TO DRIVE AND THERE WAS NO WORK TO BE DONE AS THEIR WERE NO WARNING CODES AND THE CHECK ENGINE LIGHT WAS NOT ILLUMINATED.
DRIVING ALONG AND THE POWER STEERING GOES OUT. HAS NO COMMON TIME OR CONDITIONS AS TO WHEN. HAS HAPPENED ON THE HIGHWAY, DRIVEWAY AND CITY STREETS. STEERING IS EXTREMELY DIFFICULT TO TURN. I HAVE TO STOP, PUT IT IN PARK AND RESTART. THIS MAKES IT RETURN TO NORMAL. SOMETIMES FOR A DAY OR A COUPLE OF HOURS, IT VARIES. DEALER HAS TRIED TO DOWNLOAD A FIX BUT IT'S NO BETTER. STARTED DEC 9 AND KEEPS DOING SO.
LIKE MANY OF THE OTHER COMPLAINTS LISTED FOR THIS VEHICLE. THIS PROBLEM ROUTINELY AND REPEATEDLY OCCURS ON BOTH STREET AND HIGHWAY DRIVING. AFTER SLOWING DOWN AND DEPRESSING THE ACCELERATOR, THE AUTOMATIC TRANSMISSION WILL STUMBLE AND HESITATE. BECAUSE THE VEHICLE WON'T READILY ACCELERATE, THE GAS PEDDLE IS DEPRESSED FURTHER AND THEN THE AUTOMATIC TRANSMISSION WILL DOWNSHIFT TOO MANY GEARS AND EXCESSIVE ACCELERATION AND ENGINE RPM FOLLOWS. THIS PROBLEM CAUSES EXCESSIVE ACCELERATION, WHICH COULD PLACE THE VEHICLE AND ITS OCCUPANTS INTO AN UNSAFE TRAFFIC SITUATION AND POTENTIALLY CAUSE ACCIDENT AND/OR INJURY. THE DEALER SERVICE WRITER WAS ASKED ABOUT THIS SITUATION AND RESPONDED THAT "THE TRANSMISSION WAS SEEKING THE BEST GEAR TO MAXIMIZE GASOLINE MILEAGE PERFORMANCE", WHICH REALLY DOESN'T SEEM TO MAKE SENSE IN THIS SITUATION.
TL* THE CONTACT OWNS A 2015 CHEVROLET COLORADO. WHILE DRIVING 40 MPH, THE HOOD BEGAN TO SHAKE AND PARTIALLY LIFTED UP, BUT NEVER FULLY OPENED. THE FAILURE RECURRED ON NUMEROUS OCCASIONS. 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 1,000. UPDATED 02/05/16*LJ UPDATED 03/02/16.*JB
TL* THE CONTACT OWNS A 2015 CHEVROLET COLORADO. THE CONTACT STATED THAT WHILE THE DRIVER WAS DRIVING AT 55 MPH, THE DRIVER CRASHED INTO THE REAR OF ANOTHER VEHICLE AND THE DRIVER FRONTAL AIR BAGS FAILED TO DEPLOY. AS A RESULT, THE DRIVER SUFFERED INJURIES TO THE ELBOW, THE ARMS, THE FACE, AND THE BRUISES TO THE BODY THAT REQUIRED MEDICAL ATTENTION. A POLICE REPORT WAS FILED. THE VEHICLE WAS TOWED TO A COLLISION CENTER WHERE THE FRONT BUMPER, THE RADIATOR, AND THE WINDSHIELD WERE REPLACED. THE AIR BAG FAILURE WAS UNDETERMINED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 6,000.
ENGINE INTERMITTENTLY IDLES ROUGH AND STALLS. ENGINE STALLED WHILE STOPPED IN INTERSECTION NECESSITATING A RESTART. PLACED CAR INTO NEUTRAL, RESTARTED, AND WAS ABLE TO EXIT THE INTERSECTION BUT AFTER LIGHT TURNED RED. DEALER HAS NOT BEEN ABLE TO DUPLICATE OR DIAGNOSE THE PROBLEM DESPITE TWO ATTEMPTS.
WHEN STARTING UP A HILL, AT A SLOW SPEED, THE TRANSMISSION, WILL HESITATE, ALMOST STOP, UNTIL THE GAS PEDAL IS PUSHED DOWN TO GET THE VEHICLE MOVING. THIS IS AN ONGOING PROBLEM, I HAVE BEEN TOLD BY DEALER, THAT THE TRANSMISSION IS ADAPTING TO MY DRIVING STYLE, AND WILL SOON IMPROVE.
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.
THE 2015 COLORADO HAS AN ELECTRICAL/LIGHTING PROBLEM. WHILE THE LIGHTING IS NOT A BIG ISSUE, THE FACT THAT IT MAY INDICATE A MORE SERIOUS ELECTRICAL PROBLEM IS. WHEN ENTERING THE TRUCK, THE CARGO LIGHT COMES ON, AS IT IS SUPPOSED TO, BUT WHEN EXITING THE TRUCK, THE REVERSE LIGHTS COME ON INSTEAD OF THE CARGO LIGHT. I NOTICED THIS WITH OUR FLEET VEHICLE, AND HAVE SINCE HEARD FROM MANY OWNERS WHO HAVE THE SAME PROBLEM.
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.
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 N
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.
HOOD VIBRATES A LOT WHEN DRIVING DOWN THE HIGHWAY ( 50 - 80 MPH ) - ESPECIALLY ON THE DRIVERS SIDE. *TR
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
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
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.
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
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
NHTSA publishes every complaint as the owner wrote it and investigates only a fraction. Spelling, capitalisation and judgement are the filer’s own. What carries weight is repetition: the same component failing the same way across many filings, and whether the manufacturer eventually opened a recall for it.
