2016 CHEVROLET COLORADO Complaints

RECURRING PROBLEM. INTERMITTENT PROBLEM. ENGINE HESITATES BETWEEN 1000 AND 2500 RPM. CAUSES UNEXPECTEDLY POOR ACCELERATION FROM A STOP. CAUSES UNRESPONSIVE THROTTLE. CAUSES TRANSMISSION OVERSHIFTS (SHIFTING 2-3 GEARS LOWER). CAUSES UNSAFE DRIVING CONDITIONS WHEN ACCELERATION IS LESS THAN ANTICIPATED.

HEATING SYSTEM DOES NOT WORK, NO DEFOG OR DE FROST AVAILABLE WHICH CAN RESULT IN LOSS OF FORWARD VISIBILITY, RECALL HAS BEEN ISSUED, VEHICLE HAS BEEN IN FOR CORRECTION, WAS STATED AS CORRECTED, WAS NOT, HEATING SYSTEM DOES NOT WORK, REPURCHASE OF THE VEHICLE HAS BEEN REQUESTED SINCE THE HEATING SYSTEM DOES NOT WORK, CANNOT BE CORRECTED, IS A SERIOUS SAFETY ISSUE

TRANSMISSION DOES NOT DOWNSHIFT PROPERLY UNDER ANY TYPE OF ACCELERATION (SLOW OR SUDDEN) ESPECIALLY BETWEEN 20 MPH AND 40 MPH IN NORMAL STREET TRAFFIC AND ON THE HIGHWAY. IT ALSO HUNT FOR GEARS ESPECIALLY BETWEEN GEARS 4 THROUGH 6. IT HESITATES FOR APPROXIMATELY 2 TO 3 SECONDS, FINDS A GEAR, HESITATES AGAIN, AND THEN DROPS TO AN EVEN LOWER GEAR AND OVER ACCELERATES. WHAT I HAVE OBSERVED IS THAT THE VEHICLE IS TOO EAGER TO UPSHIFT AND SOMETIMES GOES INTO 5TH OR 6TH GEAR AND DROPS THE ENGINE BELOW 1000 RPM. IT STAYS IN THAT GEAR WHEN SLOWING DOWN AND WHEN ACCELERATED IT STAYS IN THE HIGH GEAR ON BOGS DOWN AND ON TWO OCCASIONS STALLED. THIS IS DANGEROUS ESPECIALLY IN HIGHWAY TRAFFIC AND IS ESPECIALLY DANGEROUS WHEN ACCELERATING TO PASS OR ACCELERATING ON AN HIGHWAY ONRAMP TO MERGE WITH TRAFFIC. I HAVE TAKE THE TRUCK TO DEALER AT AROUND 2000 MILES. WAS TOLD THAT THEY COULDN'T FIND ANY PROBLEMS AND THEY "RESET" THE TRANSMISSION. IT RAN FINE FOR ONE DAY AND BEGAN THE PROBLEMS AGAIN. I HAVE OPERATED THE TRUCK NOW TO 6000 MILES TO SEE IF THE TRANSMISSION CAN "LEARN" ITS WAY OUT OF THIS AND IT HAS NOT. I AM GOING TO DEALER AGAIN AND IF THEY TELL ME AGAIN THAT THERE IS NO PROBLEM, I AM GOING TO FORCE THE SERVICE MANAGER TO DRIVE WITH ME FOR A DAY TO EXPERIENCE THE PROBLEM.

ENGINE REVS HIGH COMING TO A STOP. REQUIRED BOTH FEET PRESSED HARD ON THE BAKES TO EMERGENCY STOP. SPEED CONTROL QUITS WORKING THEN SERVICE-STABILITY CONTROL COMES ON, CAR STARTS TO HANDLE ACKWARDLY, PULLS TO LEFT THEN. CUT ENGINE OFF AND IT RESETS, BUT THE CRUISE CONTROL STOPS WORKING AND THEN THAT SERVICE STABILITY CONTROL COMES BACK ON.IF I DON'T PUT ON THE CRUISE CONTROL, I DON'T GET THAT STABILITY CONTROL MESSAGE SO FAR. BRAKING PROBLEM HAPPENS WHEN COMES TO A STOP. CRUISE CONTROL HAPPENS AT HIGHWAY SPEEDS BUT SOMETIMES GOING 45 MPH.

ON NUMEROUS OCCASIONS WHILE ENTERING/EXITING VEHICLE MY KNEE LIGHTLY BRUSHES THE 4 WHEEL DRIVE ENGAGE SWITCH LOCATED ON THE DASHBOARD. THIS ACTIVATES THE 4 WHEEL DRIVE ON THE VEHICLE. THIS IS HAPPENING WITHOUT MY KNOWLEDGE. SINCE THERE IS NO OBVIOUS INDICATOR ON THE DASH THE THE VEHICLE IS IN 4 WHEEL DRIVE, IF I DO NOT NOTICE THE BRIEF "ENGAGING 4 WHEEL DRIVE MESSAGE" THERE IS NO WAY OF KNOWING THAT IT IS IN 4 WHEEL DRIVE UNTIL THE VEHICLE STARTS "HOPPING" ON DRY PAVEMENT WHILE TURNING. SHOULD THIS HAPPEN AT HIGHWAY SPEED ON A CURVE THERE IS THE STRONG RISK ON A ROLLOVER. I HAVE FOUND MYSELF HAVING TO REGULARLY CHECK THE KNOB IN ORDER TO DETERMINE IF THE 4 WHEEL DRIVE IS INADVERTENTLY ENGAGED BY THIS LIGHT BRUSHING OF THE KNOB.

"THE TRANSMISSION DOES NOT DOWNSHIFT FROM A HIGH GEAR (5 OR 6) TO A LOWER GEAR WHEN SLOWING DOWN FROM 45 MPH TO 20 MPH (OR LOWER). WHEN THE ACCELERATOR IS DEPRESSED TO ACCELERATE THE ENGINE BUCKS, VIBRATES, AND DOES NOT ACCELERATE. THE ENGINE RPM DROPS TO 1,000 RPM OR LOWER. IF THE ACCELERATOR IS QUICKLY FLOORED THE TRANSMISSION DOWNSHIFTS SEVERAL GEARS LOWER AND JERKS FORWARD. THIS CONDITION HAPPENS PRIMARILY ON SECONDARY ROADS WHILE DRIVING ALONG THE ROAD AND WHEN PULLING FROM ONE ROAD INTO TRAFFIC ON ANOTHER ROAD. THE SITUATION WHEN PULLING INTO TRAFFIC IS DANGEROUS BECAUSE THE TRUCK DOES NOT ACCELERATE AS IT SHOULD. THIS TRUCK WAS PURCHASED NEW AND HAS 1200 MILES ON IT. THIS CONDITION HAS BEEN PRESENT SINCE THE TRUCK WAS PURCHASED AND THE SEVERITY VARIES WITH TRUCK SPEED AND ROAD INCLINATION. I REPORTED THE SITUATION TO THE DEALER AND THEY ATTEMPTED A FIX (HAD THE TRUCK FOR THREE DAYS) THAT SUPPOSEDLY INVOLVED A "NEW DOWNLOAD" FROM CHEVROLET, BUT IT DIDN'T CHANGE A THING. DEALER KNOWS IT DIDN'T FIX ANYTHING AND SAYS CHEVROLET MAY HAVE A "RECALL UPDATE", BUT READING ALL THE OTHER SIMILAR COMPLAINTS, I'M SUSPICIOUS. IN THE 1 MONTH I HAVE HAD THE TRUCK, I HAVE ALMOST BEEN HIT TWICE BY APPROACHING TRAFFIC BECAUSE OF HESITANT ACCELERATION. THIS IS A DANGEROUS PROBLEM AND CHEVROLET NEED TO FIX IT IMMEDIATELY. I

AT SPEEDS ABOVE 60 MPH THE SHEET METAL ON THE HOOD BEGINS TO RIPPLE, FLUTTER, AND DISTORT. THIS PROBLEM IS WELL KNOWN BY CHEVROLET. THE DEALER HAS APPLIED EXPANDING FOAM INSIDE THE HOOD UNDER WARRANTY, BUT THE METAL CONTINUES TO DISTORT AND RIPPLE AT HIGHWAY SPEED. I AM AFRAID THE HOOD SHEET METAL WILL FAIL AND THE HOOD WILL COME OFF THE VEHICLE WHILE DRIVING. CHEVROLET REFUSES TO DO ANYTHING FURTHER ABOUT IT.

TL* THE CONTACT OWNS A 2016 CHEVROLET COLORADO. WHILE THE VEHICLE WAS AT THE DEALER, THE TECHNICIAN DIAGNOSED THAT THE WIRING HARNESS HAD FRACTURED. AS A RESULT, THERE WERE VARIOUS ELECTRICAL FAILURES, INCLUDING ILLUMINATION OF THE AIR BAG AND TRACTION CONTROL WARNING INDICATORS. THE TECHNICIAN STATED THAT THE WIRING HARNESS NEEDED TO BE SHRINK WRAPPED. THE VEHICLE WAS REPAIRED. WHILE THE VEHICLE WAS IN PARK OR WHILE DRIVING AT VARIOUS SPEEDS, THE VEHICLE VIBRATED. THE VEHICLE WAS TAKEN BACK TO THE DEALER, BUT WAS UNABLE TO BE DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND STATED THAT A TECHNICIAN WOULD BE SENT OUT TO INSPECT THE VEHICLE. THE FAILURE MILEAGE WAS 176.

I LIVE IN A RURAL AREA WITH MODERATE HILLS AND MANY WINDING ROADS AND TREE OBSCURED CORNERS. WHILE DRIVING AT A MODERATE SPEED (30-40 MPH), I EXPERIENCE PROBLEMS WITH THE VEHICLE'S ABILITY TO DOWNSHIFT FROM OVERDRIVE TO ADDRESS THE INCREASING INCLINE. THE VEHICLE WILL, DESPITE NORMAL INCREASE IN FUEL PEDAL PRESSURE, LOSE RPM'S FROM APPROXIMATELY 2,000 TO 1,000. AS IT APPROACHES 1,000 RPM, THE VEHICLE BEGINS TO "STUTTER" AND "LURCH" AS THE ENGINE TRIES TO COPE WITH THE HIGHER GEAR. THERE ARE TWO "FIXES" FOR THIS; PUSHING THE GAS PEDAL DOWN FIRMLY, WHICH CAUSES THE VEHICLE TO RADICALLY DOWN SHIFT AND "LEAP" FORWARD, OR TO DROP THE TRANSMISSION LEVER TO "MANUAL" AND MANUALLY CHANGE GEARS (WITHOUT THE "LEAP" SEEN IN THE FIRST METHOD). THE END RESULT OF THE NON-MANUAL APPROACH IS TO CAUSE THE VEHICLE TO ACCELERATE RADICALLY IN AN ENVIRONMENT OF OBSCURED CORNERS AND UPHILL DRIVING. I BELIEVE THIS IS A DANGEROUS SAFETY PROBLEM AS THE AREA IS SWARMING WITH DEER, BICYCLISTS, PEDESTRIANS, ETC. I HAVE ALSO HAD "STUTTERING" INCIDENTS WHEN ACCELERATING FROM LOW SPEED, TO ENTER TRAFFIC, INTERSTATE, ETC., ALTHOUGH THESE HAVE BEEN INTERMITTENT IN NATURE. I HAVE NOTICED THAT THE VEHICLE WILL ALSO RADICALLY DOWNSHIFT GOING DOWNHILL WITHOUT WARNING AND SEEMS TO TAKE A LONG TIME TO UP SHIFT ONCE IT IS ON LEVEL GROUND - AGAIN AN INTERMITTENT ACTION. FORTUNATELY NO ONE HAS BEEN "TAILGATING" ME WHEN THIS OCCURS (A COMMON FAILING OF DRIVERS IN THIS AREA). I HAVE HAD THE VEHICLE TO THE DEALER TWICE FOR THE FAILURE TO DOWNSHIFT FOR A HILL AND THEY TELL ME CHEVROLET DOES NOT RECOGNIZE A PROBLEM WITH THE TRANSMISSION, SHIFTING, ETC. A SIDE NOTE: THIS PROBLEM DOES NOT EXIST IN CRUISE CONTROL, BUT USE OF CRUISE CONTROL ON THESE BACK ROADS WOULD NOT BE ADVISABLE.

CHEVY SAID THERE ARE NO FIXES FOR THE FOLLOWING COMPLAINTS. TRANSMISSION IS ACCEPTABLE AND SMOOTH SHIFTING UNDER LIGHT LOADS. UNDER A NEED FOR DOWNSHIFTING FOR ACCELERATION THE DOWN SHIFTING IS DELAYED OR HESITATES MOMENTARILY AND THEN THE TRUCK JERKS FORWARD TO A EXCESSIVELY LOWER GEAR & THE UPSHIFTS TO THE GEAR IT SHOULD HAVE IN THE FIRST PLACE. THE DELAY OR LAG IN DOWNSHIFTING CREATES A VERY DANGEROUS CONDITION WHEN NEEDING INSTANT POWER. THERE IS MUCH DIFFICULTY WHEN MERGING INTO TRAFFIC WHEN POWER IS NEEDED.. MANIPULATING THE MANUAL SHIFT CAN COVER UP THIS DEFECT ON SOME OCCASIONS WHEN IF YOU HAVE TIME TO PLAN FOR IT. THE TRANSMISSION ALSO SHUTTERS AT LOW LOAD MANY TIMES RESULTING IN NO POWER UNTIL YOU DOWNSHIFT. THEN THIS DOWNSHIFT IS DELAYED AND THEN BECOMES ABRUPT AGAIN. THE SHUTTER FEELS LIKE THE TRUCK IS GOING OVER SMALL BUMPS IN THE ROAD. THE TRANSMISSION SHIFTING IS CERTAINLY NOT CORRECT AND CERTAINLY RESULTS IN UNSAFE SITUATIONS. I SHOULD HAVE TEST DRIVEN THE TRUCK UNDER MORE CONDITIONS THAN I DID AND PROBABLY WOULD NOT HAVE PURCHASED IT. I HEAR THAT THIS PROBLEM CAN BE FIXED WITH AN AFTERMARKET COMPUTER UPDATE. CHEVY PROBABLY DOSE NOT WANT TO ADMIT THAT IN ORDER TO HAVE THE GAS MILEAGE RATINGS THE TRANSMISSION MUST BET THIS WAY. ALSO NOTE THAT THE 2017 COLORADO WILL HAVE AN 8 SPEED TRANSMISSION.
