2018 CHEVROLET COLORADO Complaints

WHEN THE TRUCK IS PUT IN AUTO 4WD MODE WHILE PARKED, INSTEAD OF THE 4WD ENGAGING AS NECESSARY, IT ENGAGES IMMEDIATELY UPON MOTION. THIS MAKES THE AUTO 4WD OPTION OBSOLETE.THIS WAS FIRST NOTICED WHEN I USED 4WD AUTO MODE FOR THE FIRST TIME IN OCTOBER 2018. I'VE NOTIFIED THE DEALER BUT THEY DON'T SEEM TO THINK ANYTHING IS WRONG OR NOT FUNCTIONING PROPERLY.

CHEVROLET MONTEBELLO DELEARSHIP IN CALIFORNIA REFUSED TO DO ANY WORK ON OUR 2018 CHEVROLET COLORADO. WE RECEIVED A LETTER ABOUT A RECALL ON THE AIRBAGS OF THE TRUCK AND WE TOOK THE TRUCK IN DUE TO SOME ISSUES ON THE TRUCK AND THE RECALL. BECAUSE THEY FELT THE VEHICLE WAS TAMPERED WITH THEY DENIED TO DO ANY WORK ON THE TRUCK EVEN THE RECALL OF THE AIRBAGS!!!!! THE SERVICE TECHNICIAN WE WERE WORKING WITH SAID THEY WERE NOT GOING TO DEAL WITH US ANYMORE BC I MADE A COMPLAINT TO GM AND I WOULD NEED TO DEAL WITH THEM DIRECTLY THEY REFUSED TO PROVIDE ME ANY DOCUMENTATION EVEN AFTER THEIR SERVICE MANAGER SAID THEY WOULD. THIS IS NOT ACCEPTABLE FOR THEM TO REFUSE TO FIX SUCH A MAJOR SAFETY CONCERN AND TO BE HONEST THEY ARE BEING NEGLECTFUL AND SHOULD BE HELD ACCOUNTABLE FOR BEING SO UNETHICAL.

5/20/18 AC ISSUES -- STARTS BLOWING COLD THEN WARM/HUMID THEN BACK COLD. INFORM SERVICE ADVISOR WHEN TOOK TRUCK IN (6/18/18) FOR SERVICE. TECH NOT FIND AC ISSUE. 8/7/18 TRUCK IN AGAIN -- AC STARTS BLOWING COLD AIR THEN PUTS OUT WARM/HUMID AIR THEN BACK TO COLD AIR. -- TEMP IS SET 72 AND OUTSIDE IS 85 - WHY DO I HAVE TO PUT ON AUTO TO GET COLD AIR TO BLOW OUT OR ADJUST DOWN TO GET? WHY ON AUTO IT WANTS TO FREEZE US AT 72 AND TEMP HAS TO BE ADJUSTED UP? TECH MONITOR DOORS WITH AC RUNNING & WERE WORKING AS DESIGNED -- NOTE THEY REPORT WAM TO COLD - NOT COLD TO WARM TO COLD AS I REPORTED. WELL THE ISSUE STILL HOLDS AND THE TRUCK'S CLIMATE CONTROL (BLENDING PROCESS) HAS AS ISSUE IN GETTING THE TEMP ADJUSTED ON STARTUP. 2/18/19 - ON MY DRIVE YESTERDAY WITH MY WIFE, TRUCK TEMP SET AT 74 AND OUTSIDE TEMP WAS 54 AND 40 MINUTES INTO DRIVE THE VEHICLE FOGGED UP THE SIDE WINDOWS AND I HAD TO TURN ON DEFROST. THEN THAT EVENING AS TEMP HAD DROPPED, WHEN TURNED ON TRUCK IT BLEW HOT THEN COLD THEN BACK TO HOT. THE BLENDING THAT THE SYSTEM IS DOING IS NOT WORKING CORRECTLY. NEED TO GO BACK TO THE MANUAL AC/HEAT CONTROL!

MAY 2018, MY WIFE AND I NOTICED AN OBNOXIOUS ODOR COMING FROM AC AFTER STARTUP AND BELIEVE AN AC ISSUE AS STARTS BLOWING COLD THEN WARM/HUMID THEN BACK COLD & IT PUTS OUT A MUSTY? SMELL THE SMELL GOES AWAY, BUT AFTER I HAVE STOPPED AND THEN RESTARTED TRUCK AFTER A COUPLE MINUTES AND DRIVE A COUPLE MORE MINUTES THE ODOR AGAIN PRESENTS ITSELF. IN JUNE TOOK THE TRUCK IN FOR SERVICE AND THEY SPRAYED THE AIR FILTER WITH A DISINFECTANT(?). THAT JUST MASKED THE SMELL FOR A DAY OR TWO, BUT THE ODOR STILL PRESENT. THE SERVICE TECH WAS NOT BEEN ABLE TO REPLICATE THE ISSUE. THIS IS STILL OCCURRING AND WE HAVE NOTICED THAT THE ODOR OCCURS WHEN USING HEAT TOO. INFORMED SERVICE ADVISOR IN DECEMBER WHEN TRUCK IN FOR WORK. ISSUE OF ORDER STILL CAN NOT BE REPLICATED.

NOTICED A "SHUDDERING" IN THE TRANSMISSION DURING LIGHT ACCELERATION BETWEEN 40-60MPH AROUND 1500RPM. WHOLE TRUCK VIBRATES LIKE YOU ARE DRIVING OVER RUMBLE STRIPS. ONLY 4150 MILES ON THE TRUCK!

TAKATA RECALLS HEAR WATER RUSH WITH A GURGLE NOISE FROM DASHBOARD THIS HAPPENS WHEN TAKING OFF FROM A STOP. ALSO WHEN THE VEHICLE IS IN DRIVE WITH THE FOOT ON THE BRAKES IT MAKES LOUD NOISE THEN JUMPS. ALSO PAINT ON HOOD HAS FISHEYES THE TRUCK ALSO IDOLS HIGH WHEN STARTING UP.

BRAND NEW 2018 MIDNIGHT EDITION CHEVY COLORADO LESS THAN 24HRS ON THE ENGINE AND HAD LESS THAN 900 MILES ON IT. WENT TO GO TO WORK ONE MORNING AND IT WOULDN'T DO ANYTHING. NO REVERE. NO POWER STEERING. ALL LIGHTS AND GAUGES WERE FLICKERING AND GOING CRAZY. ENGINE WAS CHUGGING AND MAKING ODD NOISES.IT WOULD NOT MOVE FROM MY GARAGE/DRIVEWAY. HAD IT TOWED IT TO NEAREST DEALERSHIP. OVER 2 WEEKS OF DIAGNOSTICS IT'S EITHER A STEERING MODULE OR A WIRING HARNESS PART. DEALERSHIP TELLS US ITS FAULTY WIRING/STEERING MODULE. IT IS AN INTERMITTENT ISSUE AND IT'S HARD TO DIAGNOSE. I REALLY FEEL THAT THIS COULD CAUSE MANY SAFETY ISSUES SINCE POWER STEERING WAS COMPLETELY OUT AND IT WANTED TO SHUT OFF ON US. THIS COULD HAVE BEEN BAD IF IT HAPPENED WHILE WE WERE DRIVING IT TO WORK. THE DEALERSHIP WE PURCHASED IT FROM HAD DONE SOME ELECTRICAL WORK BUT DID NOT DISCLOSE WHAT WAS DONE UNTIL IT QUIT WORKING AND WAS BROUGHT TO A DIFFERENT DEALERSHIP. THEY BROUGHT IT TO OUR ATTENTION WHEN IT WAS TOWED IN. THE WIRING THAT WAS DONE BEFORE PURCHASE IS WHAT'S CAUSING ALL ISSUES ELECTRONICALLY. TRUCK IS CURRENTLY IN THE SHOP WAITING FOR A PART THAT IS ON BACKORDER. WAITING FOR PAPERWORK AFTER REPAIRS ARE COMPLETED. IF THEY CAN BE COMPLETED. THEY'RE STILL TRYING TO FULLY UNDERSTAND THE ELECTRICAL ISSUES SINCE IT IS SO RANDOM. IT HAS BEEN IN THEIR SHOP FOR OVER 2 WEEKS NOW. I JUST WANT SOMEONE TO BE AWARE OF THESE ISSUES INCASE IT NEEDS TO BE RECALLED. THIS COULD BE A SCARY ISSUE IF IT HAPPENS WHILE DRIVING.

I HAVE A 2018 CHEVROLET COLORADO LT 4WD CREW CAB. MULTIPLE TIMES ON A COLD START THE ENGINE IS MISFIRING. THE CHECK ENGINE LIKE COMES ON, THE VSA, AND T/C LIGHTS ALL COME ON AND A NOTIFICATION ON THE DASH SAYING STABILITRAK IS DISABLED. THE VEHICLE SHAKES TERRIBLY. THE CHECK ENGINE LIGHT WILL FLASH AND THEN GO SOLID. I AM AN AUTOMOTIVE TECHNICIAN. I KNOW THAT A MISFIRE SHOULD SET A HARD DTC. WHEN THE VEHICLE IS TURNED OFF AND STARTED SEVERAL HOURS LATER THERE IS NO CHECK ENGINE LIGHT OR ANY OTHER LIGHT ON. THE DEALERSHIP IN MARYSVILLE, OH HAD MY TRUCK FOR 3 DAYS AND TOLD ME THEY CLEANED A BUNCH OF TERMINALS AT SEVERAL CONNECTORS. WHATEVER THAT IS SUPPOSED TO DO. THEY SAID THEY STARTED THE VEHICLE SEVERAL TIMES AFTER AND EVERYTHING WAS GOOD. THE NEXT DAY AFTER I PICKED THE TRUCK UP, IT DID THE SAME EXACT THING! EXTREMELY FRUSTRATING! I KNOW A CONTINUOUS MISFIRE LET'S UNBURNED FUEL INTO THE CATALYTIC CONVERTER WHICH LEADS TO PREMATURE BREAKDOWN OF THE CATALYST. SO MY QUESTION IS WHAT IS BEING DONE ABOUT THESE ISSUES? ANOTHER ISSUE IS WITH THE TRANSMISSION. ON A COLD START THERE IS A CLUNK NOISE. THEN WHEN YOU ARE DRIVING AT CRUISING SPEED AND YOU LET OFF THE THROTTLE AND DEPRESS THROTTLE AGAIN THERE IS A SHUDDER. ALSO, WHEN YOU COME TO A COMPLETE STOP THE VEHICLE TRIES TO JOLT FORWARD. THIS IS EXTREMELY CONCERNING ESPECIALLY ON A VEHICLE WITH ROUGHLY 18,000 MILES ON IT. THIS NEEDS TO BE ADDRESSED PROMPTLY!!

MY VEHICLE SHAKES AND SHUTTERS WHEN ACCELERATING. I HAVE BROUGHT IT TO CHEVROLET OF WESLEY CHAPEL FL 3 TIMES FOR THE SAME PROBLEM. THE PROCEEDED TO DO A "FLUSH" AND HAVE REPLACED THE TORQUE CONVERTER.
