2018 Chevrolet Colorado

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.

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 HAD TRUCK STATIONARY PARKED ON A SLIGHT INCLINE ON A DIRT ROAD FOR ABOUT 5 MINUTES WHEN I HEARD A ODD SOUND LIKE "ARRRRR CLUNK" AND MY CAR ROLLED DOWN A HILL. I HAD MY CAR ON PARK WHILE ON 4LOW WITH THE ENGINE OFF. I DID NOT HAVE MY PARKING BRAKE ON THOUGH BUT THE INCLINE WAS SO SLIGHT I FEEL I DID NOT NEED IT. MY TRUCK WAS NOT LOADED WITH ANY EXTRA WEIGHT OR ANYTHING TO CAUSE IT TO ROLL DOWN THE HILL. I TRULY BELIEVE I AM NOT AT FAULT FOR THIS HAPPENING IT IS A BRAND NEW CAR HOW COULD THIS HAPPEN? PRIOR TO THIS I WAS NOT DOING ANYTHING EXTREME TO DAMAGE MY CAR IN ANY WAY. SOMETHING MUST HAVE FAILED ON MY TRUCK.
