2018 CHEVROLET COLORADO Complaints

Ignition Key can't be removed and will not rotate all the way to the off position. Have to leave key in the ignition and the door unlocked. It does not do this all the time, but enough to know GM has a design problem and should figure out a solution and issue a recall. When I go on line I find that this seems to be a common problem with a lot of colorado owners.

2018 CHEVROLET Colorado...when driving if a side window is dropped less than an inch, vehicle shakes, vibrates and make odd noises. Raise all windows and vehicle runs smoothly. Many drivers are reporting the same problem online. Both the Colorado and same GMC vehicle having same problem. When a window is lowered the vehicle vibrates and shakes violently...one has to drop down to 30 miles and hour to make it safe to drive. Seems like a problem GMC should be able to repair without much trouble.

The Multimatic DSSV damper in the left rear lost its fluid through a leak. Various forums indicate there is a design flaw with the DSSV for the ZR2. A blown shock renders the vehicle unbalanced, and marginally safe in unexpected rough terrain or when pulling a trailer. These dampers or shocks have shafts that are too thin and poorly designed seals, causing them to leak.

Ignition tumbler and steering wheel locked. Could not turn key, could not turn wheel. Truck was is park on flat driveway. Tried all basic instructions (three adults) and then called mobile mechanic. He could not get it to turn either and could not remove steering wheel cover to access ignition tumbler to replace. Truck is three years old. Had to have it towed to dealership.

IGNITION SWITCH FULLY WON'T TURN TO OFF POSITION. ENGINE DOES TURN OFF, BUT KEY CAN'T BE REMOVED. HAPPENS FREQUENTLY AND SO FAR, STARTING IT, PUTTING IT INTO DRIVE OR REVERSE AND MOVE A BIT, THEN BACK INTO PARK WILL WORK. AT SOME THAT MIGHT NOT WORK AND I'D HAVE TO LEAVE THE KEY IN THE IGNITION AND LEAVE THE TRUCK UNATTENDED. I COULD STILL LOCK IT, BUT IF SOME KIDS SEE IT OR BREAK INTO IT, THEY COULD DRIVE IT AWAY. CHEVY KNOWS ABOUT THIS. THERE IS A SERVICE BULLETIN #PI1429B.

THIS STARTED ABOUT 3 MONTHS AFTER I GOT THE TRUCK AND HAS BEEN DOING IT SINCE. ON THREE SEPARATE OCCASIONS, TRUCK ENGINE SHUT OFF AFTER STOPPING THEN TURNING RIGHT ON CITY AND NEIGHBORHOOD STREETS. FIRST TIME I PULLED OUT ON A ROAD WHERE THE SPEED LIMIT IS 55 SO I WAS LUCKY NO ONE WAS BEHIND ME WHEN THE ENGINE CUT OUT. ON THE FOURTH OCCASION, TRUCK SHUT OFF AFTER BACKING UP FROM PARKING SPOT AND PUSHING ON GAS TO GO FORWARD. NO CHECK ENGINE LIGHTS, NO NOISES OR VIBRATIONS TO TELL ME TRUCK IS GOING TO SHUT OFF. I HAVE TO LOOK AT DASH TO SEE IF IT HAS GONE BLACK. RADIO STILL WORKS, AND I'M ABLE TO STEER OFF TO SIDE OFF THE ROAD BECAUSE IT'S STILL IN MOTION FROM AFTER THE TURN. I CAN PUT GEAR IN PARK POSITION, TURN KEY TO OFF, THEN START THE TRUCK LIKE NORMAL. HAVE GONE TO MECHANIC AND DEALERSHIP AND THEY CAN'T GET IT TO DUPLICATE. CHEVROLET HAS BEEN NOTIFIED BUT HAS SAID THEY CANNOT HELP IF DEALERSHIP CAN'T FIND THE PROBLEM. STEERING WHEEL ALSO STARTING TO GET STUCK IN TURN POSITION WHEN TURNING RIGHT. RIGHT AFTER THE TURN IT FEELS LIKE IT CATCHES IN SOMETHING AND I HAVE TO FORCE THE WHEEL BACK TO CENTER. STARTING TO HAPPEN ALMOST DAILY, BUT NOT FOR DEALERSHIP. I FEEL DRIVING THE TRUCK IS A SAFETY HAZARD FOR NOT ONLY ME BUT OTHERS ON THE ROAD.

2018 CHEVY COLORADO ZR2, 21000 MILES. ENGINE SHUT DOWN WHILE DRIVING IN MOTION ON ROAD. RESTARTED TWICE AND SHUTDOWN AGAIN TWICE. CHECK END ENGINE LIGHT CAME ON AND TRACTION CONTROL SAID IT WAS DISABLED. STARTED THIRD TIME AND PUT IN DRIVE. WOULDN'T PUT POWER FROM ENGINE TO DRIVE TRAIN. 4TH START, PUT IN DRIVE AND LIMPED BACK HOME. WAS TOWED TO CLOSEST DEALER AND THEY CLEARED ERROR CODES WITH DIAGNOSING. I SCANNED CODES BEFORE BEING TOWED AND ERROR CODES WERE U0700 AND U0100. AFTER 3 DAYS OF NO COMMS FROM 1ST DEALER HAD 2ND DEALER PICK UP VIA TOW TRUCK. THEY SAID 1ST DEALER CLEARED CODES AND COULD NOT DUPLICATE. PICKED UP TRUCK AND RAN FINE FOR A WEEK, THEN HAD SAME ISSUE ON BUSY ROAD. HAD TO RESTART, ENGINE LIGHT CAME ON AND LIMPED BACK HOME. SCANNED CODES AND RECEIVED SAME U0700, U0100. DEALER IS HAVING TOW TRUCK PICK UP TRUCK TO DIAGNOSE AND REPAIR. THIS IS A SERIOUS ISSUE CAUSING TRUCK TO SHUT OFF WHILE DRIVING AND NOT KNOWING IF IT WILL RESTART AND HAVE POWER TO DRIVETRAIN.

STARTED THE TRUCK ON A COLD MORNING, COOLING FAN KICKED IN ON HIGH WITHIN SECONDS OF START. TEMPERATURE GAUGE ON DASH NOTED TO BE INOPERATIVE AT THAT TIME. HOSES FROM RADIATOR BECAME WARM AS NORMAL, HEAT DELIVERY TO CAB ALSO NORMAL. DROVE FOR A FEW MILES WITHOUT CHANGE IN FAN SPEED. ENGINE TURNED OFF, FAN SPEED REMAINED HIGH FOR SEVERAL MINUTES. SAME PATTERN OCCURRED INTERMITTENTLY, WITH NORMAL FUNCTION OTHERWISE, INCLUDING NORMAL FUNCTION OF DASH TEMPERATURE GAUGE. CODES READ AT REPAIR SHOP DURING ONE EPISODE SHOWED PROBLEM WITH THERMOSTAT. THERMOSTAT/HOUSING REPLACED ON 2/15/21. TRUCK DRIVEN SEVERAL TIMES WITHOUT PROBLEM, BUT SEVERAL DAYS LATER, PROBLEM OCCURRED AGAIN, FAN ON HIGH, TEMP GAUGE INOPERATIVE. HAS BEEN INTERMITTENT SINCE, WITH NORMAL FUNCTION IN BETWEEN IDENTICAL MALFUNCTION EPISODES.

DUEL DRINK (COFFEE) CUP HOLDERS NEXT TO SHIFTER LEAK FROM ANY DRIP OR SPILL. IT IS NOT DESIGNED TO CONTAIN ANY SMALL OR INSIGNIFICANT SPILL OR DRIP. ANY LIQUID LEAKS DOWN DIRECTLY UPON SENSITIVE EXPOSED ELECTRICAL DIP SWITCHES NEEDED TO SHIFT THE TRUCK. THIS INCLUDES THE RUBBER RESERVOIR (DOES NOT HOLD WATER AND DIRECTS LIQUIDS THROUGH KNOBBIES TO UNDERSIDE) AND THE HARD PLASTIC CONTAINER (HARD PLASTIC COMPARTMENT HAS DRAINAGE HOLES THAT LEAD DIRECTLY TO TOP OF ELECTRICAL SWITCHES) IS DESIGNED LIKE A STRAINER. REPLACING ELECTRICAL SWITCHES COST ME $632. I CANNOT USE THE BEVERAGE HOLDERS AS I INFERRED THAT THEY WERE DESIGNED TO USE, TO NOT ONLY HOLD MY BEVERAGE IN PLACE BUT CONTAIN IT FROM LEAKING ABOVE ANY SENSITIVE EXPOSED ELECTRICAL SWITCHES. I UNDERSTAND THE SAME DESIGN IS IN THE CHEVY EQUINOX THIS YEAR. GOOD LUCK.

WE WERE DRIVING ON A CITY STREET AND WE STARTED TO SMELL BURNED PLASTIC, WE PULLED OVER AND THE SEAT WHERE MY 3 MONTH OLD BABY IN HER CAR SEAT STARTED TO SMOKE, I IMMEDIATELY TOOK THE CAR SEAT OUT AND FLAMES STARTED TO COME OUT FROM BEHIND THE SEAT, POLICE AND FIRE DEPARTMENT CAME AND EXTINGUISHED THE FIRE, FIRE DEPARTMENT TOLD ME IT'S A ELECTRICAL RELATED FIRE.THEY ARE NO SEAT WARMERS ON THE REAR SEATS.
