At the beginning of November I was out shopping, when I returned to my vehicle, the driver side door would not open. Luckily I was fit enough to crawl through from the passenger side. I promptly called the Chevy dealership for an inspection/ repair. I feel this was an emergency situation. I didn-??t even want to think about what would happen if I were in a vehicle accident, and couldn-??t get out, or, no one could get in. I was able to get an appointment at the dealership for November 16, 2023. My Chevy is always parked in covered garage, there was no warning sign of anything going wrong. They checked it at my appointment, but because they couldn-??t open it, they decided to order all the assembly parts, which I had to pay for ahead of time. My next appointment for the repair wasn-??t set till January 31, 2024. I never knew how important a functional door would be. Very inconvenient, and dangerous.

The check engine light came on because the coolant fan runs for a while after vehicle is shut off. This ended up being due to a thermostat failure. I did have this repaired in Novemver 2023 but what is interesting is that one of my sisters, who also owns a Chevy Captiva had this same thing repaired earlier in 2023 and now my other sister who owns a Chevy Equinox has this same issue now, 2/5/24, and will look into having it repaired. Is this just a coincidence or is this a defective problem that the manufacturers should address?

Unable to remove key from ignition switch. Engine shuts off, but ignition is still on. In short time the battery goes dead. Per the dealer, the customer needs to lift hood and disconnect negative battery cable to prevent the battery from dying and the vehicle needing towing. Most customers under the hood with wrenches is a dangerous situation. Per the internet this is common with this vehicle, and the dealer fix is not a sure cure. GM needs to investigate and come up with a permanent fix that does not let customers stranded, carrying wrenches, and working under the hood to keep going, especially at night.

For at least 6 months now My ignition key goes in and starts normally. When parked the key goes back one notch and freezes. Cannot pull it out or put back to off position. This is sporadic. Have been to 2 Chevrolet dealers who simply stated they cannot duplicate the issue so they don't want to throw parts at it. On you tube there are many videos of how people are handling this.. If I had a emergency run to a hospital or something of a time constraint I cannot do it because i am stuck for at least a half hour until it moves again. Now about $280 into diagnostic fees that Chevrolet claims they know nothing about so they are doing nothing. Imagine that click the key 5 or 6 times video it and then say cannot duplicate the problem. I hope this leads to someone acknowledging an issue. Thanks

We reported issues with our thermostat to our dealer back in September of 2022. The vehicle would not defrost or heat. We were then told the thermostat required replacements but there was no part in existence and they would notify us when it became available. After following up numerous times with no actionable timeline from the dealer we consulted with a secondary mechanic who confirmed the issue was related to a thermostat sensor malfunction and would require a replacement thermostat. Again we were told that the item was not available from GM and we would be contacted when more information was available. A SPAC case was created by our dealer in October of 2022, notifying the system of the urgent need and our dealer has followed up numerous times that GM has not provided any timeline for replacement. I have also filed a separate claim in January of 2023 to GM customer service notifying them of the ongoing issue and escalating to upper management. I have not heard back on mitigation or rectification plan for our issue. This ongoing issue is a major safety concern that has rendered my vehicle unfit for operation. I am unsure why GM is not making this major safety concern a priority because we are now in the middle of a Chicago winter we-€™re temperatures are regularly below freezing. I cannot defrost my windows or maintain a safe cabin temperature. This is unsafe for me to operate let alone use the vehicle to transport my child because of the immediate danger it would place her and I in. I am now paying for a vehicle that has sat inoperable in my driveway for 4+ months with no end in site and opening is up to additional damages because it has had to remain inoperable for an extended period of time.

The HVAC module temp door is cracked, as previously seen in the 2015-2016 recall for Chevrolet Colorado-€™s and GMC Canyons. This forces the temperature to be 33 degrees F colder than requested. This poses a risk to those that live in cold winter climates, as there is no heat available in the vehicle.

While driving my truck overheated and Antifreeze was leaking inside the car. Due to the antifreeze leaking my windows were fogging up pretty quickly and I couldn-€™t see. Therefore having to stop in the middle of the road cause I could t see almost getting hit. Now I can not drive the my car due to the smell making my kids and myself sick. It also states in the paper work after buying my truck new that this is a defect part. This would be a heater core. Thanks for this heater core being inside the truck I almost was hurt.

The key repeatedly will not turn to off position and cannot be removed from ignition. This results in my having to leave the key in the ignition. IE: at the grocery store, at the post office, at the drug store etc. I have taken to dealership. The first time for 2 days and they said they could not duplicate the problem. The 2nd time it happened in the service drive. The service advisor saw it but the technician said could not duplicate. This could result in stolen vehicle or dead battery depending how long I have to leave in the on position. The TSB on this says replace shifter control assembly.

Key cannot be removed from ignition. I bought my truck 6 months ago and it-€™s been in the shop 3 times bc I can-€™t remove my key. Last time it left me stranded at my veterinary clinic at 1 AM after dealing with an emergency because the battery died. It appears as though I am not the only one having this issue

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.

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.

The truck vibrates, stutters some times when driving. Went to dealer he said it has been happening in trucks. He said thicker trans oil should fix it. Is this just a band aid for a bigger problem. Would like your view. Thanks.

My Colorado has completely shut down/powered off when making a right hand turn. Twice now. I'll be coming to a complete stop, accelerating through the turn and then all of the sudden, without warning, the truck loses all power. No flashing dash, nothing. I have to coast to the shoulder of the road, turn on the hazards, put in park, and restart the vehicle. This has happened twice now. From some online forums I've read, the problem only seems to get worse and has happened to others around 30-40 mph. My car is still under manufacturing warranty for another 500 or so miles. I took my truck into a certified Chevy repair shop and after a week of troubleshooting and trying to recreate the problem, they have found "nothing" wrong with the car. If this doesn't get fixed and continues to occur, it's only a matter of time before an accident happens.

2018 Colorado develops a shutter when moving up an incline from speeds of 45 to 60 mph on highways. Truck has 33,000 miles 10,000 miles I placed on the truck the remainder was while the truck was part of a fleet. Just noticed this shutter at 32,000 miles. Though it was tires, but turned out not to be the issue.
