All the sensors seem to not be functioning correctly. Doesn't tell me the right measurements for the wheels, gas, over heating. Right front passenger door locks/unlocks when it wants. It chokes up when trying to accelerate. Theres a rattling noise that comes from under the car. First time I took it to the dealership, they stated it was a bolt that had come loose on the exhaust pipe. They placed a new one which lasted a year and a half and now its back to making the noise. I took it again to the dealership, this time they claimed they couldn't find anything. My airbag sensor keeps coming on constantly. My fuel sensor claims 116 miles one moments and 5 or 6 minutes later, it says I have 50 miles. My car was over heating and low on Anti-freeze, the car never notified it was over heating.

Touch screen not responsive, apple carplay unavailable can’t connect phone, will randomly tap apps and puts calls on hold. Will flip pages on its own and even turn the back up camera on when driving down the road

P2738 Pressure Control Solenoid Valve 6 Control Circuit Low Voltage. Whenever you drive, the transmission will go into limp mode every now and then. It will say low oil pressure and throw another code of P0700 MIL Request From TCM. This is a common issue that I have researched and would like to know a way forward. I've only had the vehicle for 6 months. Within city limits as long as you don't push the accelerator too much (50mph within 2 minutes) it runs ok until the vehicle comes to a stop. Also, when you get on and off of the freeway, same issues make it go into limp mode in which you will have to shut the truck off and start up after a few minutes to reset.

The ignition switch will frequently lock when turning off and not allow the electrical system to fully turn off and prevent you from removing the key. It happens randomly but has been increasing in frequency.

Jan 24, 2025

Key can't be removed when the truck is in park. Locks go up and down when vehicle is moving. Transmission stuck in 3rd gear. Stabilitrack and traction control indicator lights appear on dashboard. Exhaust brake and traction control switches don't work.

Key cannot be removed front ignition. Put in park but does not release key . Unlocks doors but does not lock steering wheel or release key . Have to do several tricks to get key loose . No one in repair community seems to be able to fix or understand how to repair.

“Service trailer brake system” won’t turn over but will crank Transmission shifting very hard around 3rd and 4th gear

Jan 11, 2024

Truck bought in United States for use in US. All dash displays ( child or person in back seat or passenger seat, and gauges, emergency or vital messages, warnings etc) are in a foreign language. I only speak and read english. In addition, may go into mode where it changes channel and volume every few seconds which is distracting. Chevrolet dealer (Valmark) says they want 100-200 usd to diagnose and 2000.00 to replace. Reset did not fix. Vehicles for US should be in common language. Chevy should diagnose and repair free of charge. Screen is locked/frozen and cannot be accessed. Spoke with Ian at chevy hdqtrs who said diagnose fee is up to dealer, i will have to pay. Chevy forums say common problem and chevy won’t repair.

He wiring harness to the 4wd kept coming on which wouldn’t allow me to ingage. Mountain Chevy citified mechanic found a chafing on the wiring harness. After filing it my truck started to light up like a Christmas tree, Stability service, trailer brake service, Locker service, Power streering service and they done turn off. Which is caused by more chafing wires that are to close to components of the engine bay getting to hot. Now my power steering turns off and when driving the truck it kicks on and make me loose control of the vehicle. Big diffect on Chevys manufacturing this vehicle. I’m not able to drive it and now they keep telling me that they don’t have the part or can’t find it.

The vehicle will not stop unlocking itself. even while moving.

Ignition interlock will stick and not allow key to be taken out of the ignition. The truck is off, in park and parking brake applied but key is stuck in ignition. Have to rapidly push shifter lever button until it unlatches and the key is able to be taken out. Occurs 2-3 times per week.

Dec 28, 2022

A/c lines near driver side wheel well has chafed through fuel line and wire harness.Causing a couple thousand dollars in damage.Nor warning indicators leading up to either incidents. My chevy dealership mis diagnosed it twice and has now found the issue. Fuel lines leak can cause fires and as far as the electrical issue I've been left stranded with my 3 year old daughter a couple of times..Have looked up forums and many people have had the same issue.

May 27, 2022

The wiring harness was touching the air condenser line. The line gets hot when air conditioning is used. It melted causing my truck to throw a lot of random alarms. It also would turn my cruise off and make it down shift all of a sudden startling me. Melted wires are also a fire hazard. There is a bulletin for wire harness chafing that GMC knows about this issue. If it had melted something major and shut my truck down while driving down the interstate it would put me and anybody around me in danger. It was wired back together but is still not fixed. Might need a new wiring harness.

Occasionally the ignition key cannot be turned to the OFF position and cannot be removed. After shifting to Park, the key can be turned to position 1 (ACC) but will not turn all the way to position 0 (OFF) and therefore the key cannot be removed from the steering column. So far I have been able to temporarily resolve the problem by re-starting and stopping the engine several times. The number of times the cycle must be repeated is not consistent. On one occasion, the driver was not able to remove the key so the key was left in position 1 for several hours. This resulted in a drained battery and the truck would not start. We needed a mechanic to come by and jump start the truck.

I put my car in reverse and the back up camera on the head unit is blue

Electrical problems with Chevrolet Mylink display. A variety of errors include backup camera flashing on at highway speeds, hands free phone calls put on hold, navigation screen flashing random inaccurate destinations. These distractions impair safe operation of the vehicle. Dealer verified issues but could not perform diagnostics on a timely basis. Issues continue.

It trys to constantly shif gears and when it does finnally shifts it starts to shutter bad have to pull off the road and shut it off sometimes it will stop it and sometimes it doesn't it very annoying and can't be safe or good I know that this specific transmission has a recall but for some reason my truck didn't I haven't even made my first car payment I noticed it the very first day I took it home the service porter said I had it in for wheel drive when it wasn't than blamed it on the tires .the dash lights go out .the radio changes stations Werth out me even touching the steering wheel

El vehículo en muchas ocasiones no quiere encender el tablero, se vuelve loco como si quisiera apagar ah blim, queda mucho ah, las luces del tablero y la radio se encienden y apagan

Jun 25, 2021

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.

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.

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.

HAPPENED 3 TIME NOW. EACH TIME I WAS DRIVING SLOWLY, IDLING ALONG, IN PARKING LOT. EACH TIME I WAS IN GEAR (DRIVE) MOVING AT IDLING SPEED E.G. PARKING LOT CRAWL. ALL ELECTRICAL SHUTS OFF JUST LIKE I HAD TURNED THE KEY OFF. ALL LIGHTS OFF, AC OFF, RADIO OFF, ENGINE OFF, EVERYTHING OFF. NO WARNING LIGHTS, NOTHING - JUST TURNS OFF. VEHICLE RESTARTS FINE WITH NO IMMEDIATE RECURRENCE. FOR SOME REASON IT SIMPLE TURNS ITSELF OFF. IT'S GOING TO BE BAD IF THIS HAPPENS WHEN PULLING OUT INTO TRAFFIC.

I JUST LEFT WORK, MY TRUCK WAS PARKED FOR 8, HRS. AFTER 3, MINUTES OF DRIVING THE SERVICE STABILITY TRACK LIGHT CAME ON. AFTER A COUPLE MINS. I TURNED DOWN A MAJOR HIGHWAY AND THEN THE FOLLOWING WARNING LIGHTS CAME ON: CHECK ENGINE, LOW FUEL ( IT WAS HALF FULL), TRACTION CONTROL, DRIVE WITH CAUTION, STREARING ASSIST OFF. THE ELECTRICAL PANEL WENT CRAZY AND I LOST POWER TO THE ENGINE. I PULLED OVER AND CALLED CHEVY ROADSIDE ASSIST. THEY TOWED THE TRUCK TO COX CHEVROLET, WHERE I PURCHASED THE VEHICLE BRAND NEW ONLY A YEAR AGO. THEY COULD NOT DUPLICATE THE ISSUE AND I HAD TO DRIVE IT BACK HOME. THIS IS CLEARLY A MALFUNCTION. I DO NOT FEEL SAFE DRIVING THE IT.

TRUCK SHAKES AT SPEEDS ABOVE 55 MPH. AT 65 MPH MY PHONE WILL FLY OFF THE MAGNET MOUNT ON THE WINDSHIELD; WATER AND ICE SHAKE AS IF BOILING AT 70 MPH AND ABOVE. SOMETIMES THE VEHICLE FEELS LIKE IT IS COMING APART IT SHAKES SO HARD. WHEN THE VEHICLE WAS TWO MONTHS OLD IT STOPPED ON A CITY STREET IN ARLINGTON VA AND WAS UNDRIVEABLE. AFTER A TIMEOUT PERIOD OF 10-15 MINUTES IT WAS DRIVEABLE BUT AT 10 MPH IT WHINED AS IF THE TRANSMISSION OR ENGINE WAS GOING TO BLOW UP. AT 20-25 MPH IT WAS A SCREAMING DEMON AND HAD TO BE TOWED TO THE DEALERSHIP (BROWNS) WHO FOUND NO RECORD IN CAR COMPUTER SYSTEM OF FAULT. BATTERY OR ELECTRICAL SYSTEM WAS COMPLETELY DEAD ON 7 JUNE 2019 WITH ABOUT 10,200 MILES. DEALERSHIP KNEW I HAD APPOINTMENT AND I ASKED FOR TOW BUT THEY DON'T PROVIDE A TOW FROM REED-LALLIER. ONSTAR WAS OF LITTLE HELP SO I CALLED MY USAA INSURANCE ROADSIDE ASSISTANCE TO GET TRUCK JUMP STARTED; I MISSED APPOINTMENT AND THEY CANCELED APPOINTMENT THAT MORNING WHICH WAS TO CHECK FOR SHAKING AND ALSO 2ND OIL CHANGE. GMCUSTOMERCARE TOOK MY CONCERNS AND ASKED MY RESOLUTION WHICH WAS CHECK BATTERY FOR BAD CELL, BE AWARE OF FIRST TRANSMISSION PROBLEM IN ARLINGTON VA AND THE CURRENT PROBLEM OF VEHICLE SHAKING. I AM A RETIRED PARATROOPER WITH VERIFIABLE SEVERE NERVE DAMAGE TO MY BACK AND LOWER LEGS AND THIS VEHICLE CAUSES SERIOUS PHYSICAL AND NEUROLOGICAL PROBLEMS WHEN DRIVING HIGHWAY SPEEDS.

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.

THE DISPLAY FOR THE BACKUP CAMERA IS ON AT FULL BRIGHTNESS. THERE IS A CONTROL KNOB TO DIM THE INTERIOR LIGHTING AND DISPLAY, BUT WHEN THE VEHICLE IS PUT INTO REVERSE, THE DISPLAY GOES TO FULL BRIGHTNESS AND CANNOT BE CONTROLLED BY THE BRIGHTNESS CONTROL KNOB. AT NIGHT, THE PASSENGER SIDE MIRROR IS NOT USEABLE SINCE THE BACKUP DISPLAY IS SO BRIGHT. THIS ALMOST RESULTED IN ACCIDENTS WHEN BACKING UP INTO A PARKING SPOT.
