2016 CHEVROLET COLORADO Complaints

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.

DRIVING AT ABOUT 60 MILES A HOUR AND LOST ALL POWER ENGINE WAS RUNNING BUT GOING NO WERE ALL LIGHT WERE LITE ON DASH LIKE YOU TURN KEY ON BEFORE STARTING THANK GOD NO ONE WAS COMING THE OTHER WAY OR THE CAR BEHIND ME WOULD HAVE HIT ME. HE WAS A GOOD DRIVER. SHUT IT OFF AND RESTARTED IT THEN IT WOULD RUN WITH ALL LIGHT ON DASH EVEN BRAKE LIGHT AND ANTI SKID LIGHT AND IT SAID ON INFRO. RUNNING AT REDUCED SPEED. DROVE TO MY HOME A SLOW SPEED IT LET ME. SHUT IT DOWN LET IT SIT A FEW MIN. RESTARTED IT STILL THE SAME. SHUT IT DOWN FOR ABOUT TEN MIM. RESTARTED IT. SEEM TO RUN OK BUT CHECK ENGINE LIGHT IS TILL ON NOW I AFRAID THE WILL JUST RESET IT AND SAY IT IS OK. AND NEXT TIME I WON'T BE SO LUCKY. IT HAS 5500 MILES ON IT. I DID SEE MY LIFE BEFORE MY EYES HOPPING IT DOSE NOT HAPPEN TO OTHERS. TAKING DEALER TOMORROW IT HAPPEN AT ABOUT 5PM 3/24/2016

TL* THE CONTACT OWNS A 2016 CHEVROLET COLORADO. THE CONTACT'S VEHICLE WAS REAR ENDED BY ANOTHER VEHICLE. AS A RESULT, THE CONTACT'S VEHICLE REAR ENDED THE PRECEDING VEHICLE. THE AIR BAGS FAILED TO DEPLOY. THE CONTACT SUSTAINED LEFT WRIST, LEFT ARM, SHOULDER, AND NECK INJURIES THAT REQUIRED MEDICAL ATTENTION. A POLICE REPORT WAS FILED. THE VEHICLE WAS TOWED TO A BODY SHOP FOR REPAIRS. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 200.

TRANSMISSION DOES NOT DOWNSHIFT PROPERLY FROM UPPER GEARS (5,6) TO LOWER RANGE WHEN DECELERATING FROM 40 + MPH TO UNDER 20 MPH. VEHICLE WILL EXHIBIT LOSS OF POWER FROM BEING IN TOO HIGH OF A GEAR RANGE, CAUSING "CHUGGING", AND THEN A SUDDEN BURST OF POWER AS YOU TRY TO ACCELERATE. DEALER RESET ECM FOR TRANSMISSION; PROBLEM PERSISTS. TYPICALLY OCCURS ON RESIDENTIAL OR NON-FREEWAY STREETS, BUT HAS HAPPENED ENTERING A FREEWAY ENTRANCE RAMP.
