2016 Chevrolet Colorado

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 14,500 MILES ON IT. THIS CONDITION HAS BEEN PRESENT SINCE THE TRUCK WAS NEW AND THE SEVERITY VARIES WITH TRUCK SPEED AND ROAD INCLINATION.

I HAVE A 2016 CHEVY COLORADO 4 CYLINDER TRUCK AT THE DEALER AGAIN. HAD IT IN ABOUT 8-10 MONTHS AGO ON THE ENGINE REVIVING REAL HIGH WHEN COMING TO A STOP. THEY SAID IT WAS PROBABLY THE HILL ASSIST SYSTEM AND NOTHING THEY COULD DO. NOW IT'S CHRONIC. IT CAN REV TO 2200 RPMS AS I COME TO A STOP. I HAVE TO KICK IT IN NEUTRAL TO KEEP FROM HITTING A KID IN A CROSSWALK OR THE CAR IN FRONT OF THE. BOTH FEET ON THE BRAKES. AND, WHEN I PUT IT IN NEUTRAL, IT CAN REV UP TO 4000 RPM'S. IT'S BACK AT THE DEALER NOW AND THEY DON'T HAVE ANY SERVICE BULLETINS ON IT. I TEST DROVE A V-6 300 HP MODEL WHILE THERE AND IT DID THE SAME THING 2 TIMES AND THE SALESMAN DIDN'T NOTICE, BUT IT NEVER GOT OVER 1800 RPMS. SO,THEY HAVEN'T FIXED IT. BUT THEY'RE SINCERELY TRIED BUT I THINK IT'S THE SYSTEM NOT THE DEALER. THE HILL ASSIST SYSTEM DOESN'T PICK UP ON IF YOU'RE LEVEL OR GOING DOWN A HILL ANYMORE. JUST REVS UP, AND IT'S IN 1ST GEAR WHEN COMING TO A STOP.THE TORQUE IS TREMENDOUS ON THE BRAKES. IT'S AN ACCIDENT WAITING TO HAPPEN. I DON'T THINK THE DEALER IS NEGLIGENT IN ANYWAY, I THINK IT'S THE COMPUTER DESIGN ON THAT HILL ASSIST HAS GONE HAYWIRE ON US. *TR

TL* THE CONTACT OWNS A 2016 CHEVROLET COLORADO. WHILE DRIVING VARIOUS SPEEDS, THE VEHICLE SUDDENLY HESITATED WHEN ATTEMPTING TO ACCELERATE. THE VEHICLE WAS TAKEN TO THE DEALER (FERMAN CHEVROLET OF TARBON SPRINGS) ON SEVERAL OCCASIONS, BUT THE FAILURE COULD NOT BE DUPLICATED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 100. UPDATED 08/03/07*LJ *TR

WHEN GOING DOWN HILL THE TRANSMISSION DOWNSHIFTS HARD AND JERKS YOU FORWARD. YOU CANNOT ACCELERATE AGAIN UNTIL IT HITS 10MPH THEN IT IS HARD TO GET THE ACCELERATION GOING AGAIN. THIS COULD CAUSE AN ACCIDENT IF SOMEONE IS CLOSE BEHIND YOU ESPECIALLY A BIG TRUCK THAT CANNOT STOP QUICKLY. WHEN YOU ARE ACCELERATING ON A HILL IT DOES NOT WANT TO GO AND YOU HAVE PUSH THE ACCELERATOR DOWN THE ENTIRE WAY AND THEN JERKS FORWARD AND TAKES OFF. THIS HAPPENS ALL OF THE TIME GOING DOWNHILL AND UP HILLS. I HAVE 24,000 MILES ON MY TRUCK NOW AND IT HAS HAPPENED SINCE I PURCHASED THE TRUCK.

MAY BE THE ABS/SPEED SENSOR WIRE GOING TO THE HUB WAS DAMAGED WHEN THE HEADLAMP WAS DAMAGED BECAUSE I NOTICED THE SPEEDOMETER WAS JUST GOING UP AND DOWN. (HAYWIRE) A NUMBER OF THINGS ALSO COULD BE THE REASON FOR THIS SUDDEN NOTICES APPEARING IN THE DIC. WE FINALLY HIT WARM WEATHER AND ITS +2 DEGREES OUTSIDE, THE ROADS ARE MELTING CAUSING ALL THESE ERROR CODES TO APPEAR. (MELTING ICE AND SNOW INTERFERING WITH THE COMMUNICATION/ERROR SYSTEM????) MY ASSUMPTION IS THIS BECAUSE THERE IS A CONSTANT LEAK FROM THE TOP OF THE CABIN COMING FROM THE LIGHT/STORAGE AREA IN THE MIDDLE ON WARM DAYS. WHEN THE WEATHER WARMS UP, THE EFFECTS OF SUCH LEAKS COULD CAUSE BUILT-UP ICE/SNOW TO MELT. I'M SURE YOU ARE AWARE THIS TYPE OF LEAKING IS DUE TO OUR EXTREME CLIMATE AND WEATHER PATTERNS IN NUNAVUT. I'M SURE SIMILAR PATTERNS EXIST IN SOUTHERN CANADA. BUT ITS WHEN THE WEATHER WARMED UP AND I'M GUESSING THE WET ROADS CAUSED THIS ISSUE. MY STEERING IS JUST OUT.

NOTICED IMMEDIATELY AFTER PURCHASE WITH 18 MILES. NOTICED AT SLOWER SPEEDS UNDER 45 MPH THE TRUCK WOULD UP-SHIFT TO A HIGHER GEAR WHEN LETTING OFF THE ACCELERATOR. UPON DEPRESSING THE ACCELERATOR AGAIN THE TRUCK WOULD HESITATE, JERK,PING, OR JUST PLAIN NOT ACCELERATE UNTIL EXCESSIVE PRESSURE WAS PLACED ON THE ACCELERATOR. AT THIS POINT IT WOULD DOWN-SHIFT HARD A COUPLE OF GEARS AND CAUSE UNSAFE ACCELERATION IN HIGH TRAFFIC SCENARIOS.

AT APPROX. 3500 MILES STARTED EXPERIENCING SHIFTING ISSUES. WHEN SLOWING DOWN TRANSMISSION WANTED TO STAY IN 5TH OR 6TH GEAR. ATTEMPTS TO ACCELERATE CAUSED THE TRUCK TO BOG DOWN UNTIL IT SHIFTED TO A LOWER GEAR TO ACCELERATE AGAIN. WHEN IN CRUISE CONTROL PROBLEM WAS REALLY BAD. WOULD LOOSE AS MUCH AS 5-8 MPH BEFORE A LOWER GEAR WAS FOUND TO MAINTAIN SPEED IN HILLY CONDITIONS. I TOOK VEHICLE IN FOR ITS FIRST SERVICE AT APPROX. 6000 MILES AND HAD DEALER CHECK TRANSMISSION. THEY REMAPPED SHIFT POINTS TO SPEC SOFTWARE. THIS WAS A TEMPORARY FIX. ISSUE IS SLOWLY RETURNING. I HAVE WATCHED ON CONTROL PANEL AT TRANSMISSION OIL TEMP ( TRUCK HAS TRAILER TOWING PACKAGE ETC. THIS IS A CLUSTER FEATURE AVAILABLE.) SEEMS TO SHIFT PROPERLY UNTIL OIL REACHES 100 DEGREES PLUS THEN ISSUE ARRIVES. DEALER RELAYED THERE HAD ONLY BEEN A TECH SERVICE BULLETIN HAS BEEN TO RESET MAP/SHIFT POINTS. RECENTLY PULLED MY BOAT WITH THIS TRUCK AND TRANSMISSION SHIFTED FINE. REALLY WOULD LIKE THIS ISSUE FIXED BECAUSE OTHER THEN THIS PROBLEM REALLY LIKE THE TRUCK.
