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.

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 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.

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.

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.

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.

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.

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.

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.

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.
