2018 CHEVROLET COLORADO Complaints

WHEN TURNING THE KEY INTO THE IGNITION POSITION THE VEHICLE WILL GIVE A RANDOM DOWNSHIFT UNLESS THE BRAKE PEDAL IS PRESSED DOWN. ALSO EXPERIENCING A ROUGH DOWNSHIFT BETWEEN 2ND AND 1ST GEAR WHEN STOPPING AS SMOOTHLY AS POSSIBLE. VEHICLE AS BEEN IN AND OUT THE DEALERSHIP WITH THE PROBLEM STILL EXISTING.

FRONT END CLUCKING WHEN GOING OVER BUMPS OR PULLING INTO DRIVEWAYS AT VEY MINIMUM SPEED.

ABOUT A YEAR AGO, I STARTED GETTING A SLIGHT SHUDDER IN MY TRANSMISSION SO I TOOK IT TO THE DEALER FOR REPAIR. THEY COULDN'T GET IT TO SHUDDER. SEVERAL TIMES I'LL BE DRIVING DOWN THE ROAD AT OR AROUND 45MPH AND THE TRUCK WILL START SHUDDERING SO BAD I FEEL LIKE I HAVE TO PULL OFF THE ROAD. EVERY TIME I TAKE IT TO THE DEALER FOR REPAIR I END UP LOSING MY TRUCK FOR A DAY AND THEY TELL ME THEY CAN FIND ANYTHING WRONG EVEN THOUGH THIS IS A KNOWN ISSUE AND THERE IS A TSB OUT TO FIX THE ISSUE.

WHILE DRIVING ON CITY STREET AND HIGHWAY, TRANSMISSION SHIFTING AT SPEEDS OF 25MPH,45MPH,55MPH START VIBRATING ALSO COMING TO A STOP FEEL LIKE A REAR END BUMP.

THE TRUCK VIBRATES , STUTTERS SOME TIMES WHEN DRIVING. WENT TO DEALER HE SAID IT HAS BEEN HAPPENING IN TRUCKS. HE SAID THICKER TRANS OIL SHOULD FIX IT. IS THIS JUST A BAND AID FOR A BIGGER PROBLEM. WOULD LIKE YOUR VIEW. THANKS.

I HAVE A 2018 CHEVROLET COLORADO 3.6L. I HAVE HAD A RATTLE NOISE ON COLD START THAT WOULD HAPPEN EVERY SO OFTEN. NOW THAT I'M 1K MILES OUT OF POWERTRAIN WARRANTY THIS RATTLE NOISE HAPPENS JUST ABOUT EVERY TIME I START MY TRUCK. IT IS CAUSED BY THE VARIABLE TIMING ACTUATOR ON THE CAMSHAFT. I AM AN AUTOMOTIVE TECHNICIAN, AND I'M VERY FAMILIAR WITH VARIABLE TIMING ACTUATORS. THE PROBLEM IS THE LOCK PIN IN THE ACTUATOR DOES NOT FUNCTION PROPERLY WHEN YOU TURN THE VEHICLE OFF CAUSING IT TO DRAIN ALL THE OIL OUT OF IT. THIS CAUSES THE ACTUATOR TO RATTLE AROUND UNTIL IT GET OIL PRESSURE. THIS WILL EVENTUALLY CAUSING ISSUES WITH YOUR TIMING CHAIN AND OTHER COMPONENTS INTERNALLY IN THE ENGINE. VERY DISTURBING THAT GM KEEPS MAKING VEHICLES THAT WORK FINE, USUALLY, UNTIL THEY HAVE GOTTEN OUT OF WARRANTY. LET ME ALSO STATE THAT I REGULARLY CHANGE MY OIL WITH THE RECOMMENDED OIL AND WELL BEFORE IT'S DUE. NOT VERY HAPPY!

I AM WRITING TO INFORM YOU OF A SAFETY ISSUE WITH MY 2018 CHEVROLET COLORADO. WHEN PUTTING THE VEHICLE IN PARK THE IGNITION KEY WILL NOT RELEASE. CHEVROLET DOC# 4811390 DOCUMENTS A FLEET WIDE PROBLEM WITH THE COLORADO. THERE HAS BEEN NO RE-CALL ISSUED BY CHEVROLET TO CORRECT THIS SAFETY ISSUE. I GOT MY COLORADO REPAIRED AT A COST OF $642.15. I LOOKED AT THE SHIFTER THAT WAS REMOVED FROM THE TRUCK, AND FOUND THAT THE MICRO SWITCH THAT ACTIVATES WHEN THE VEHICLE IS PLACED IN PARK HAD A BROKEN MOUNTING POST CAUSING IT TO BE MISALIGNED. I HAVE INCLUDED PICTURES OF THE SWITCH AND MOUNTING POST. *JS

MY COLORADO HAS COMPLETELY SHUT DOWN/POWERED OFF WHEN MAKING A RIGHT HAND TURN. TWICE NOW. I'LL BE COMING TO A COMPLETE STOP, ACCELERATING THROUGH THE TURN AND THEN ALL OF THE SUDDEN, WITHOUT WARNING, THE TRUCK LOSES ALL POWER. NO FLASHING DASH, NOTHING. I HAVE TO COAST TO THE SHOULDER OF THE ROAD, TURN ON THE HAZARDS, PUT IN PARK, AND RESTART THE VEHICLE. THIS HAS HAPPENED TWICE NOW. FROM SOME ONLINE FORUMS I'VE READ, THE PROBLEM ONLY SEEMS TO GET WORSE AND HAS HAPPENED TO OTHERS AROUND 30-40 MPH. MY CAR IS STILL UNDER MANUFACTURING WARRANTY FOR ANOTHER 500 OR SO MILES. I TOOK MY TRUCK INTO A CERTIFIED CHEVY REPAIR SHOP AND AFTER A WEEK OF TROUBLESHOOTING AND TRYING TO RECREATE THE PROBLEM, THEY HAVE FOUND "NOTHING" WRONG WITH THE CAR. IF THIS DOESN'T GET FIXED AND CONTINUES TO OCCUR, IT'S ONLY A MATTER OF TIME BEFORE AN ACCIDENT HAPPENS.

IT HAS AN INTERMITTENT SHUDDER AT NO PARTICULAR SPEED AND A KIND OF TUGGING AT SLOW ACCELERATION SPEEDS, LIKE A QUICK UPSHIFT AND THEN DOWN AGAIN.
