2017 CHEVROLET COLORADO Complaints

WHOLE VEHICLE SHUTTERS WHEN ACCELERATING ANYWHERE BETWEEN 35 AND 75 MPH. THIS HAPPENS WHILE DRIVING STRAIGHT ON A CITY STREET OR HIGHWAY. IT IS EQUIVALENT TO RUNNING OVER RUMBLE BARS EVERY OTHER SECOND ON A COMPLETELY SMOOTH ROAD. THE TACHOMETER CAN ALSO BE SEEN JUMPING 100-200 RPMS DURING THE SHUTTERS.

CHEVY SHAKE!.. BEEN EXPERICING A HEAVY SHAKE/VIBRATION SPEEDS OVER 45MPH, IN CITY.. MORE SO ON HIGHWAY TRAVEL, LOOK UP SEVERAL COMPLAINTS ABOUT THE COLORADO AND ALL PRETTY MUCH HAVE THE SAME PROBLEM? GM DID NOT ISSUE A RECALL ON THESE TRUCKS..HOWEVER ITS OFF THE TWO YEAR WARRANTY. I DID DO RESEARCH ASSUME IT THE DRIVESHAFT, WHEEL BALANCE TRANSMISSION, THE LIST GOES ON. GM DEALERS KNOW OF THE,PROBLEM, BUT DECLINE TO FIX THE PROBLEM..IT SEEMS TO BE GETTING WORSE AS I DRIVE IT.

IT FEELS LIKE I AM RUNNING OVER RUMBLE STRIPS WHEN GOING 40-60 MPH AND LOW RPM. A BRIEF INTERNET SEARCH REVEALS THAT THIS IS A COMMON ISSUE THAT APPEARS TO BE RELATED TO THE TRANSMISSION. THE ISSUE BEGAN RECENTLY. I HAVE 40K COMMUTER MILES ON THE TRUCK.

TRANSMISSION SHUDDERS AND VIBRATES. HAPPENS USUALLY AROUND 55-60 MPH, AFTER THE FLUID REACHES ABOUT 80 DEGREES. HARD SHIFTING ALSO FROM FIRST TO SECOND GEAR. GM IS AWARE OF THIS PROBLEM YET CHOOSES TO DO NOTHING ABOUT IT. TRUCK IS OUT OF WARRANTY(40K) SO THEY WANT $400 TO FLUSH TRANSMISSION. IT'S A SHAME THAT GM WON'T STAND BEHIND THEIR PRODUCTS. WHEN WILL THEY BE HELD ACCOUNTABLE?

THE TRANSMISSION HAS LOCKED UP THE REAR WHEELS ON DE ACCELERATION/DOWNSHIFT CAUSING LOSS OF CONTROL. THIS HAS HAPPENED MULTIPLE TIMES AND HAS BEEN BROUGHT TO THE ATTENTION OF GM. THE TRUCK IS A SAFETY ISSUE AND NEEDS TO BE TAKEN OFF THE ROAD. GM RECOGNIZES THE TRANSMISSION IN THESE VEHICLES ARE HAVING MAJOR ISSUES BUT FAILS TO ADDRESS THE PROBLEMS.

TRANSMISSION SHUDDERS WHEN GOING DO THE ROAD. HAPPENS AT BOTH LOWER SPEEDS AND AT HIGHER SPEEDS IN TOWN AND ON THE INTERSTATE. HARD SHIFTING AS WELL WHEN VEHICLE IS NOT UP TO OPERATING TEMPERATURE.

TWICE NOW MY 2017 W/~41000 MILES HAS GONE INTO INSTANT, NO WARNING OR GRACE PERIOD, BUT AN INSTANT DROP TO A FORCED 10 MPH IN THE MIDDLE OF TRAFFIC, THIS LAST TIME ON A HIGHWAY WITH NO SHOULDERS DURING RUSH HOUR. THE THREE CODES THROWN THE FIRST TIME (I DON'T HAVE THE CODES FROM THE SECOND TIME BUT THE DEALER IS ORDERING A NEW ECM BASED ON THE U0401 CODE): RC (RADIO CONTROLS): B1325 - CONTROL MODULE POWER CIRCUIT - LOW VOLTAGE EBCM (ELECTRONIC BRAKE CONTROL MODULE): U0401 - INVALID DATA RECEIVED FROM ENGINE CONTROL MODULE - INVALID DATA ECM (ENGINE CONTROL MODULE) P200C DIESEL PARTICULATE FILTER (DPF) HIGH TEMPERATURE ALONG WITH THE CODES THE CHECK ENGINE, STABLITRAK, AND TRACTION CONTROL LIGHTS CAME ON - HOWEVER BRAKING WAS NOT AFFECTED! REGARDLESS, THIS PROGRAMMED 'LIMP' MODE IS INSANELY RECKLESS WITH TOTAL DISREGARD FOR THE SAFETY AND WELFARE OF THE VEHICLE OCCUPANTS, THERE IS ABSOLUTELY NO SAFE PLACE OR REASON TO DELIBERATELY CRIPPLE A VEHICLE WHILE IN TRAFFIC! SOME EUROPEAN MANUFACTURES AT LEAST GIVE YOU A WARNING WITH SEVERAL ENGINE RESTARTS TO LET YOU DRIVE NORMALLY TO SAFETY AND THEN A DEALER FOR SERVICE ' BUT APPARENTLY EMISSIONS LAWS IN THE US TAKE PRECEDENCE OVER HUMAN LIFE. LIMP MODE CAN BE DISABLED FOR EMERGENCY VEHICLES BUT THE DEALERSHIP TOLD ME IT WAS ILLEGAL FOR THEM TO DO IT FOR ME. THE DEALERSHIP HAS BEEN GREAT BUT LIMITED TO WHAT THEY CAN DO BECAUSE OF GM REQUIREMENTS. THEY ARE CURRENTLY LOOKING INTO THE PROBLEM AND HAS ORDERED A NEW ECM AS A SECOND PHASE IN TROUBLESHOOTING THE ISSUE (FIRST WAS REPROGRAMMING THE ECM) HOWEVER THERE IS STILL NO EXCUSE FOR FORCING A VEHICLE INTO LIMP-MODE WHILE IN USE - I HAVE LOST ALL FAITH IN THIS VEHICLE AND GM AND CANNOT TRUST IT FOR MY OWN YET FAMILIES SAFE USE.

I HAVE THE DSSV SHOCKS ON MY ZR2. IT HAS 58,000 MILES ON IT AND THE DSSV SHOCKS ARE LEAKING. TO MY KNOWLEDGE THIS SHOCK IS SUPPOSED TO BE FOR THE LIFE OF THE VEHICLE. I KNOW THERE WAS A RECALL ON SOME 2015-2017 DSSV SHOCKS MINE IS A 2017 BUT I HAVE NO RECALL AND MY SHOCKS ARE LEAKING LIKE THE RECALLED SHOCKS. SINCE THE SHOCKS ARE NOT WORKING PROPERLY IT HAS A LOT OF BODY SWAY AND IS SOMEWHAT UNSTABLE I BELIEVE THE REASON FOR THIS IS BECAUSE THE DSSV SHOCKS ARE NOT WORKING PROPERLY. BOTH OF MY REAR SHOCKS ARE LEAKING AND THE FRONT SHOCKS SEEM TO BOTTOM OUT IN EVERY BUMP. HERE IS THE RECALL NUMBER I FOUND #17345. THIS TALKS ABOUT THE ROD BEING BRITTLE AND CAUSING A LEAK

REAR CAMERA DOES NOT WORK 100% OF THE TIME, THIS HAS BEEN HAPPENING FOR SEVERAL WEEKS. IT GOES BLUE WITH NO PICTURE AND A SERVICE CAMERA MESSAGE. CAMERA WAS REPROGRAMMED BY DEALER ON 12/16/19, CAMERA AGAIN FAILED ON 12/17/19 - SAME ISSUE. VEHICLE RETURNED TO DEALER ON 12/18/19 - CAMERA WAS REPLACED, THE MORNING OF 12/19/19 - CAMERA FAILED AGAIN. THIS HAPPENS WHEN VEHICLE IS PLACED IN REVERSE AND CAMERA IS SUPPOSED TO ACTIVATE. IT ALSO HAS APPEARED TO HAPPEN AS THE TEMPERATURES HAVE GOTTEN LOWER HERE IN THE MIDWEST. AS VEHICLE WARMS UP - CAMERA FUNCTION RETURNS TO NORMAL.

ON 25 OCTOBER 2019, WHILE MOVING FORWARD AFTER BACKING OUT OF THE PARKING SPACE AT MY WORK, THE TRUCK BEGAN AN UNCOMMANDED TURN TO THE LEFT. WITH SIGNIFICANT FORCE I WAS ABLE TO STRAIGHTEN THE STEERING WHEEL. IN LIGHT OF THE POTENTIAL LACK OF STEERING CONTROL, I HAD THE TRUCK DELIVERED TO THE COURTESY GMC DEALERSHIP IN LAFAYETTE, LOUISIANA FOR REPAIR. ACCORDING TO THE REPAIR RECEIPT, THE ELECTRIC BELT DRIVE RACK AND PINION STEERING GEAR WAS REPLACED AND THE TRUCK WAS RETURNED TO ME ON 30 OCTOBER 2019. ON 22 NOVEMBER 2019, AGAIN WHILE DRIVING THROUGH THE PARKING LOT AT MY WORK THE TRUCK WENT INTO AN UNCOMMANDED LEFT TURN. THE ACTIONS OF THE TRUCK WERE NEARLY IDENTICAL AS I EXPERIENCED IN THE FIRST TRUCK LOSS OF CONTROL EVENT. I DELIVERED THE TRUCK TO COURTESY GMC IN LAFAYETTE, LOUISIANA. WHEN THE CUSTOMER SERVICE ADVISOR TURNED THE TRUCK INTO THE SERVICE BAY, A LOUD METAL-TO-METAL SOUND WAS HEARD FROM THE FRONT OF THE TRUCK. ON 4 DECEMBER 2019, I MET WITH THE CUSTOMER SERVICE ADVISOR AND THE AUTOMOTIVE TECHNICIAN AT THE COURTESY GMC DEALERSHIP TO DISCUSS THE STATUS OF THE TRUCK. THE AUTOMOTIVE TECHNICIAN STATED THAT HE WAS GOING TO CONTACT GMC ABOUT THE ISSUE THE NEXT MORNING. ON 5 DECEMBER 2019, I WAS CONTACTED BY THE AUTOMOTIVE TECHNICIAN WHO INFORMED ME THAT HE HAD DISCUSSED THE ISSUE WITH AN ENGINEER AT GENERAL MOTORS CORPORATION. THE ENGINEER ADVISED THE AUTOMOTIVE TECHNICIAN TO REPLACE THE PART THAT WAS PREVIOUSLY REPLACED, BUT ORDER THE PART THROUGH A DIFFERENT PARTS WAREHOUSE. THIS WAS STRANGE TO ME AS I WOULD BELIEVE THAT THE PARTS FROM ANY WAREHOUSE WOULD BE ACCEPTABLE. ON DECEMBER 2019, THE TRUCK REPAIR WAS COMPLETED AND WAS RETURNED TO ME. THUS FAR, THE TRUCK HAS OPERATED PROPERLY.
