2016 Chevrolet Colorado

ON 6/6/16 I STARTED HAVING THE TROUBLE. AFTER BACKING UP AND PUTTING THE TRUCK IN GEAR, THE TRUCK WOULD SURGE FORWARD WITHOUT TOUCHING THE GAS PEDAL. THIS ALSO OCCURRED ON 6/11/16, 6/17/16 AND 6/23/16. ON 6/23/16 I WAS AT SURDYKES PORT 20 MARINA AT THE LAKE OF THE OZARKS. AFTER BACKING OUT OF THE PARKING SPACE I PUT IT IN GEAR. THIS TIME IT WAS MUCH MORE THAN A SURGE. IT LITERALLY SHOT FORWARD AND EVEN THE BRAKES DIDN'T HELP BECAUSE WITHIN 3-4 SECONDS MY TRUCK AND I WERE IN THE LAKE. FINALLY GOT THE WINDOW TO BREAK SO I COULD ESCAPE. JUST BEFORE I WENT IN THE LAKE THE TRUCK STRUCK AN OLD GOLF CART AND JET SKI TRAILER THAT WERE PARKED THERE AND TOOK THEM INTO THE LAKE ALSO.

WHILE DRIVING THE COLORADO, THE TRANSMISSION GETS SO CONFUSED ON WHAT GEAR TO BE IN AND THE SHIFT PATTERNS ARE THE CRAZIEST I HAVE EVER EXPERIENCED. FROM 40-20MPH, STOP AND GO TRAFFIC, THIS TRUCK'S TRANSMISSION CLUNKS, SHIFTS HARD, STUTTERS AND CANNOT FIGURE OUT WHICH GEAR TO BE IN. IT'S VERY FRUSTRATING. NOT TO MENTION, WHEN TRYING TO PASS, THERE IS ZERO ACCELERATION FELT WHEN FLOORING THE PEDDLE. I AM SO FRUSTRATED WITH THIS TRANSMISSION AND MANY DAYS DURING THE TO AND FROM WORK COMMUTE, I FEEL AS IF I AM GOING TO GET REAR-ENDED BECAUSE OF THIS TRANSMISSION. IT'S ANNOYING WHEN DRIVING BUT STRESSFUL AS WELL, BECAUSE I FEEL AS IF MY SAFETY IS IN JEOPARDY DUE TO THIS "LEARNING" TRANSMISSION. IT'S SO DISAPPOINTING.

--- "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 1,500 MILES ON IT. THIS CONDITION HAS BEEN PRESENT SINCE THE TRUCK WAS NEW AND THE SEVERITY VARIES WITH TRUCK SPEED AND ROAD INCLINATION. THE SITUATION HAS BEEN REPORTED TO THE DEALER AND TO CHEVROLET CUSTOMER SERVICE. NO CORRECTIVE ACTIONS HAVE YET TO BE MADE."

WHEN MERGING ONTO I-70 FREEWAY FROM ON-RAMP, I APPLIED THROTTLE TO MOVE INTO THE TRAFFIC FLOW. ENGINE "STUMBLED" AS IF IN A DEAD SPOT. TRUCK DID NOT ACCELERATE AND APPEARED TO BE LUGGING BADLY. TRANSMISSION WAS IN TOO HIGH A GEAR AND SEEMED TO BE SEARCHING FOR CORRECT GEAR. DURING THIS TIME ONCOMING TRAFFIC WAS FORCED TO BRAKE AND THERE WAS A NEAR MISS OF HAVING A REAR-END COLLISION. ALL I COULD DO WAS WATCH IN THE REAR VIEW MIRROR AS TRAFFIC CONVERGED ON ME. THIS "DEAD THROTTLE / WRONG GEAR" ISSUE HAS HAPPENED REPEATEDLY ON SURFACE STREETS BUT LUCKILY ON SURFACE STREETS I WAS NOT IN SUCH A CRITICAL SITUATION. THIS IS A PROBLEM THAT HAS BEEN REPORTED REPEATEDLY AND AT MANY PLACES ON THE INTERNET. WHEN WILL NHTSA FORCE GM TO ADDRESS THIS ISSUE? HOPEFULLY YOU WILL ACT BEFORE THIS RESULTS IN SERIOUS INJURY OR FATALITIES (IF IT ALREADY HAS NOT). PLEASE ACT!

MY 2016 CHEVY COLORADO CREW CAB Z71 4X4 VIBRATES AT HIGHWAY SPEED. THE DEALERSHIP HAS REPLACED ONE TIRE, BALANCED X 3 AND ROTATED AND ROAD FORCE TESTED. THE PROBLEM PERSISTS. I WAS TOLD BY THE SERVICE MANAGER THAT BECAUSE I BOUGHT AN OFF ROAD TRUCK WITH ALL SEASON TIRES IT WILL VIBRATE ABOVE 70 MPH. I FEEL IT IN MY SEAT, IT APPEARS TO BE COMING FROM THE REAR OF THE TRUCK. THE EMPTY PASSENGER SEAT VISUALLY VIBRATES. IT STARTED AFTER THE FIRST OIL CHANGE AND TIRE ROTATION AT 6000 MILES.

APPROACHING AN INTERSECTION AND OBSERVED A YELLOW LIGHT. I WAS TRAVELING 35MPH AS POSTED AND APPLIED THE BRAKES ONLY TO HAVE THE PEDAL GO ALL THE WAY DOWN TO THE FIRE WALL. THE TRUCK HAD NO BRAKING POWER AND ONLY SLOWED TO ABOUT 15MPG AFTER APPLYING FOR ROUGHLY 40-50 YARDS. I ENDED UP RUNNING INTO THE INTERSECTION COLLIDED WITH ANOTHER VEHICLE THAT PROCEEDED ON GREEN.

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.

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 6,500 MILES ON IT. THIS CONDITION HAS BEEN PRESENT SINCE THE TRUCK WAS NEW AND THE SEVERITY VARIES WITH TRUCK SPEED AND ROAD INCLINATION. THE SITUATION HAS BEEN REPORTED TO THE DEALER AND TO CHEVROLET CUSTOMER SERVICE. NO CORRECTIVE ACTIONS HAVE YET TO BE MADE.

WHILE DRIVING THE VEHICLE OVER 40+ MPH AND THEN REDUCING SPEED DUE TO TRAFFIC TO 20 MPH, AND THEN ACCELERATING THE ENGINE AGAIN BETWEEN 21-28 MPH IT SEEMS TO BOG DOWN THE ENGINE ALMOST AS IF THE TRANSMISSION SHIFTS INTO TO LOW OR HIGH OF A GEAR AND MAKES THE VEHICLE FEEL LIKE IT'S BUCKING/JERKING WHEN TRYING TO ACCELERATE BETWEEN 21-28 MPH AND THEN A BURST OF SPEED. VEHICLE DOES IT ALL THE TIME BETWEEN THESE SPEEDS. VEHICLE WAS BOUGHT BRAND NEW HAD IT CUSTOM ORDERED AND ONLY HAD 9 MILES ON IT SO I KNOW IT'S NOT A ISSUE FROM SOMEONE ELSE DRIVING IT VEHICLE CURRENTLY HAS 1,200 MILES IS A V-6 CREW CAB

THE LOW BEAM HEADLAMPS ARE TOTALLY INADEQUATE. WHAT FOLLOWS IS THE CONTENTS FROM TWO EMAILS SENT TO THE DEALERSHIP SERVICE MANAGER. I ALSO HAVE NIGHT TIME VIDEO THAT ILLUSTRATES THE PROBLEM WHICH ALSO SHOWS THE LOCATION OF THE VEHICLE BY GPS ON GOOGLE MAPS. COMMENTS IN THE EMAIL REFER TO BOTH STATIONARY AND MOVING VEHICLE OBSERVATIONS. I WOULD LIKE TO FIND OUT IF THIS ANOTHER STUPID GOVERNMENT MANDATE THAT PUTS PEOPLE AT RISK.
