2016 Chevrolet Colorado

TL* THE CONTACT OWNS A 2016 CHEVROLET COLORADO. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 70 MPH, A LOUD POPPING NOISE CAME FROM THE ENGINE AREA BEFORE THE SPEED SUDDENLY DECREASED TO 40 MPH. DURING THE FAILURE, THE STEERING ASSIST, STABILITRAK, FOUR WHEEL DRIVE AND TRAILER BRAKING SYSTEM WARNING LIGHTS ILLUMINATED. THE FAILURE HAD OCCURRED ON MULTIPLE OCCASIONS. THE VEHICLE WAS TAKEN TO THE DEALER BUT THE FAILURE WAS UNABLE TO BE DUPLICATED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED. THE FAILURE MILEAGE WAS 5,700. UPDATED 02/03/17*LJ

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.

WHILE DRIVING THE 2016 COLORADO, THE TRANSMISSION/ENGINE SEEMS TO HAVE TROUBLE SHIFTING AND ACCELERATING AND THE SHIFT PATTERNS ARE ERRATIC IT SEEMS, MAYBE ITS THE FUEL EFFICIENT CRAP THAT SHUTS DOWN CYLINDERS, MAYBE ITS THE TRANS? . EXPERIENCED IT ON HIGHWAYS AND LOWER SPEEDS, STOP AND GO TRAFFIC, TRUCK'S TRANSMISSION CLUNKS, SHIFTS HARD AT RANDOM AND STUTTERS ALLOT . IT'S AGGRIVATING. WHEN TRYING TO PASS, SEEMS TO BE ZERO ACCELERATION FELT WHEN FLOORING IT THEN SUDDENLY KICKS IN (ROUGHLY)..LIKE OH HEY-I NEED TO GO.. I COULD GET IN A WRECK-ENDED BECAUSE OF THIS AND I BETTER NOT TRY TO PASS ANYONE.. I FEEL MY SAFETY COULD BE AT RISK WITH AS MUCH HESITATION THEN SUDDENLY LURCHES AS IT HAS. I SEE QUITE A FEW COMPLAINTS ALREADY CONCERNING THIS AND/OR DESCRIBING JUST ABOUT THE SAME ORDEAL. DAILY - BUT RANDOM - CITY AND HIGHWAY, TURNING, STRAIGHT ETC. BASICALLY ANY SITUATION BUT IDLE.

ENGINE SEEMS TO LAG UNDER QUICK ACCELERATION. PROBLEM OCCURS MOST OFTEN WHEN ACCELERATING FROM A TURN OR WHEN CHANGING LANES UNDER ACCELERATION. SPEEDS OF OCCURRENCE MOSTLY APPROXIMATELY 20-25 MPH. REQUESTED CHECKS AND SERVICE AT A DEALERSHIP ONLY TO BE GIVEN A SERVICE BULLETIN FROM GM STATING THIS WAS A NORMAL PART OF THE TRACTION MANAGEMENT SYSTEM. MY PREVIOUS VEHICLE (2014 SILVERADO) WAS ALSO LISTED ON THE BULLETIN, BUT THE PROBLEM WAS NEVER NOTICED ON THIS VEHICLE. I SEE THIS ISSUE AS AN INCREASED RISK OF A COLLISION WITH THE HIGHEST RISK BEING A REAR END COLLISION. THIS NEEDS TO BE ADDRESSED AND FIXED.
