  The engine coolant temperature gauge is stuck at approximately 160•F. Cooling fans are running at high speed constantly. The thermostat is stuck in the open position. The vehicle is less than 100,000 miles. There is a “Special Coverage Bulletin N242484760” that has indicated the issue is occurring regularly with my type of vehicle but my specific VIN is excluded due to misplaced parameters. The part is readily available at the dealership in which we are getting the part fixed because so many vehicles of my make and model are having this issue. The cost of the repair will be $1,200 and will be out of pocket because my VIN is excluded but clearly affected by the same faulty system for the coolant. This is a mistake as my vehicle is have the exact same issue as all of the others “covered” in the special coverage. We are seeking an appeal and want to file a complaint that my vehicle is excluded and will have to pay $1,200 where other customers will not be required to do so.

  The contact's son owned a 2021 Chevrolet Colorado. The contact stated that while her son was driving on a county road at an undisclosed speed, the vehicle inadvertently crashed into a tree 4-6 feet away from the road, and caught fire. No further information was available on the occurrence of the crash. The contact stated that the air bags may have failed to deploy. The fire was extinguished with the assistance of the fire department. The contact's son may have been pronounced dead at the scene. The contact's son was transported out of the vehicle with the assistance of emergency units and was airdropped to the hospital, where it was diagnosed that he sustained brain hemorrhage and third-degree burn on 65% of his body. The contact was unsure whether a fire department report was filed. A police report was filed. The vehicle was towed to an auto body shop where it was totaled. The dealer and the manufacturer were not notified of the failure. The failure mileage was approximately 5,000.

• 12/18/2025· SERVICE BRAKES,ENGINE

  In December 2024, at under 50,000 miles, my 2021 Chevrolet Colorado suffered complete brake failure caused by vacuum pump failure. The vacuum pump failure led to irreparable internal engine damage, requiring complete engine replacement under warranty. Sudden, complete brake failure in traffic could have led to a serious accident causing injuries or death to myself and/or others. The component was inspected by the manufacturer and the service advisor at the dealership stated this was "kind of a known issue on Colorados". There were no warning lamps, messages, or symptoms of the problem prior to the failure. This vacuum pump failure is documented in GM Technical Service Bulletin #21-NA-268, which addresses vacuum pump failures on other GM vehicles. The identical failure mode in my 2021 Colorado demonstrates this is a systemic manufacturing defect, not an isolated incident.

I AM ABOUT 60 YEARS OLD AND HAVE OWNED MANY, MANY VEHICLES - WE HAVE NEVER SEEN A WINDSHIELD BREAK SO FAST AND SO SEVERELY. WE DID AN INTERNET SEARCH AND THERE ARE MANY OTHER CHEVY COLORADO OWNERS THAT HAVE MADE THE SAME OBSERVATION - MANY ARE SAYING IT IS CHEAP, UNUSUALLY THIN GLASS FOR FUEL ECONOMY OR FOR LESS EXPENSE, OTHERS SAY CHEVY HAS NOT INSTALLED THEIR WINDSHIELDS WITH THE PROPER AMOUNT OF ADHESIVE BEHIND IT. OWNERS SAY THE AFTER MARKET REPLACEMENT DOESN'T EASILY BREAK ON IMPACT LIKE THIS FACTORY ORIGINAL WINDSHIELD DOES. I AM NOT A SCIENTIST - ALL OUR FAMILY KNOWS IS THAT IT WAS NOT SAFE TO HAVE THIS FACTORY WINDSHIELD ON THIS NEW TRUCK AND WE DON'T FEEL SAFE DRIVING THE VEHICLE WITH A WINDSHIELD THAT DOESN'T PROTECT US PROPERLY WHILE ON THE HIGHWAY. THIS WAS ONLY ONE IMPACT ON THE GLASS AND THE WHOLE WINDSHIELD IS DAMAGED SIGNIFICANTLY TO WHERE YOU CAN FEEL THE SHARP EDGE WITH YOUR FINGER FROM THE OUTSIDE OF THE VEHICLE.

The contact stated that while driving at an undisclosed speed, the vehicle shuddered and failed to decelerate as intended while the brake pedal was depressed. An unknown message was displayed. In addition, the contact stated the vehicle failed to respond properly while the accelerator pedal was depressed. Upon inspection, the contact noticed an abnormal engine oil leak. The vehicle was towed to the residence. The vehicle was later towed to a local dealer, where it was diagnosed with an exploded brake booster and metal shavings inside the engine. The vehicle remained at the local dealer unrepaired due to the cost. The local dealer could not guarantee that the repairs would correct the failure. The manufacturer was made aware of the failure.

  Starting my 2021 Chevy Colorado Zr2 in the morning and noticed the "service power steering, drive with care message. 40,000 miles. No power steering. This would clear after leaving vehicle sit and restarting. After reading many articles and found the recall notice for 2015 colorados. Based off of postings I didn't drive it due to the possibility of losing power steering while on the highway, which had happened to several people after restarting and clearing the error. I think GM never corrected the issue and is present in newer models. I took my vehicle in for the repair of the power steering gear and it was very costly. I feel GM should issue another recall, specifically with the possibility of losing power steering on a crowded highway is a major safety concern.

  I'm reporting a safety issue with the head lights on this vehicle, 2021 Chevrolet Colorado LT. The low beam head lights are woefully insufficient for night driving. The light emitted is non-existent with any light from oncoming vehicles. This is well known buy other owners of this model truck, and immediately noticeable to anyone who has driven my own vehicle. I have tried 2 different types of bulbs to improve the situation with no improvement. There are upgraded lights available as an option if you order the vehicle that way, but most models on the lot do not have this option. The cost to have the vehicle retro-fitted with the optional headlights is well over $1000. in parts and labor. I have owned older vehicle with the same style /strength blubs with no issue, but this vehicle is dangerous to drive at night with the standard headlights, especially in inclement weather.

This also creates a safety issues as now I am taking my eyes off the road to try and stop the problem. The infotainment system is failing yes the truck is available for inspection. I have taken video of the problem and sent it to the dealer. The vehicle has not been inspected by police or insurance rep, as far as manufacturer as this truck has been back to the dealer more then 4 times I fell that would be the manufacture as they are certified by GM. GM knows that there is an issue with the infotainment system, not sure why they have not done a recall on this unit. No warnings are given before this happens.

  Today while driving my brakes got super hard. Had to use my entire weight to get it to stop and still was moving forward. Had to use the emergency brakes and a prayer. Luckily I wasn’t on the highway or it would’ve been a deadly accident. When I opened the hood the camshaft sensor was broken loose. Mind you I had taken the truck to the dealer a while back for a rattling noise at 1500 RPM and they couldn't figure out the issue. They replace the catalytic converter under warranty. But kept making the same noise around the same RPM. Obviously it wasn't the converter. My truck has 43,136 miles only. 2021 Colorado 2.5 Luckily I’m alive today but this must be taken care of as soon as possible. I read a lot of Colorado’s seem to have the same issues. Needs a recall.

  I was on my way home from work and I was on Highway 16 in Washington state near Port Orchard and I was driving 64mph and all vehicles in front of me were all breaking slowing down pretty fast and when I pressed down on my brakes the brakes were totally stiff I could not stop and had to drive on the side of the road and passed 20 plus cars and was finally able to come to a stop. If I had no where to go I would’ve hit the car in front of me at a high rate of speed potentially causing a major or deadly accident. They were working fine 5 minutes before that. I think it is a major issue that will cause fatalities in the future if this problem isn’t taken care of. I’ve never had a vehicle do this and I’ve been driving for 38 years.

  I have taken my vehicle into the shop twice for an issue with the transmission. The first time they did a software update on the vehicle. They said that that would fix the issue. The vehicle was working fine for a week I took the vehicle back to the shop because it was making a clunking noise again when I put it in reverse. I recorded the incident of the clunking noise and I provided it to the service manager. They kept the vehicle for two days and stated that they were unable to replicate the issue. Even though I sent them a video they tried to tell me that it is normal for the vehicle to make a clunking noise when put in reverse. Upon further investigation online and speaking with people that know how to work on cars they stated to me that that is not normal. I have determined that multiple other Colorado’s have had this issue based on what I found online at this point in time Chevy need to do something about this or refund my money.

  Beginning at approximately 80,000 miles I began to notice I could not remove the key from the ignition switch at times. Turning the vehicle on and off, shifting repeatedly into park, turning the steering wheel and pressing the brake had no effect. I now have 90,000 miles and the problem occurs about half of the time when trying to exit the vehicle. It is dangerous to leave the vehicle with the key still in the switch. I called the dealership and they said they were familiar with the problem and if it was like others they had encountered, it would require changing out the shifter mechanism. I took the Colorado to the dealership on 9/10/2025 and the diagnostics showed that it was a switch problem in the shifter. The repair was $720.15 which I had completed. The shop people said it was a fairly frequent issue with that model and some others

  This is to inform you of a safety-related vehicle service which may appear as a safety-related defect. Not only does it have the potential to affect each (1) vehicle which is serviced at such a facility but it also has the potential to affect (2) multiple vehicles across the federal interstate highway system as well as (3) properties and (4) human life. Every vehicle traveling on a roadway, bridge, overpass, through a tunnel, through mountain passes, construction zones, etc may be at increased risk in encountering any vehicle serviced at such a facility if such improper service is not discovered and corrected prior to catastrophic failure.

This has been going on for a while and the truck only has 27,000 miles. I've called multiple chevy dealers (including the one I bought it from) they all want a 250 diagnostic fee! This should be under warranty. This problem is dangerous. I have seen I am not the only one having this issue. This issue needs to be investigated and recalled!

  My 2021 Chevy Colorado experienced a distinct bucking and shuddering sensation under slow acceleration at lower RPMs, specifically when shifting between 2nd and 3rd gear. There were no dashboard warning lights or malfunction codes prior to the issue. The defect was officially reproduced, inspected, and confirmed by a GM technician at a certified Chevrolet dealership on October 28, 2025, at 46,437 miles. Diagnostic scanning using GM’s GDS software explicitly confirmed that the Torque Converter Clutch (TCC) slip speed was exceeding 100 RPM when the low-speed shudder occurred. The dealership determined the component was failing and replaced the entire torque converter assembly under warranty. This documentation is submitted to prove that the TCC defect remains uncorrected in post-2019 vehicles. My sister’s identical 2021 Colorado is now experiencing the same defect at 59,000 miles, but her symptoms have progressed significantly worse to include a severe high-speed drivetrain shudder alongside the low-speed acceleration bucking.

Check engine light came on again in mid August 2023. Found P0024 code and had had to replace the cam actuator again. This time GM has part on backorder, like they are fixing systemic issue with part. They could only replace by getting from another dealer. Still charged me for part even though it was just replaced 12months ago. Would like to know if this is a systemic issue with GM.

  I own a 2021 Chevrolet Colorado Lt Extended Cab 2WD. The rear differential has failed prematurely at 70000 miles. the failure caused loud whining/grinding noises, vibration, and unsafe driving conditions. After researching online, i found many other 2021 Colorado owners reporting the same issue with rear differential failure, often at relatively low mileage. This indicates a widespread defect in the differential assembly. There are existing GM Technical Service Bulletins (20-NA-034, 20-NA-156) related to axle/differential noise and machining defects, but GM has not issued a recall or extended warranty coverage. Differential failure can lead to loss of power to the wheels or lockup while driving, which poses a serious safety risk. I request that NHTSA investigate this issue and require GM to issue a recall or Special coverage adjustment for the affected vehicles.

• 08/12/2021· POWER TRAIN

  I purchased a brand new Colorado earlier this year. The vehicle currently has about 9,000 miles on the odometer. On two recent occasions within 1 1/2 weeks of each other while driving at highway speeds, there was a clunk noise and the transmission acted as if it had been shifted into neutral. The truck would not accelerate, and the RPMs were very high as I was pushing the accelerator and the vehicle was not responding but the engine was revving. This was an extremely scary and unsafe situation as cars were behind me and I narrowly avoided being hit as I tried to get over to the side of the road without any ability to accelerate. The first time it happened, after placing the vehicle in park and waiting a few minutes, I was able to get it back into gear and I drove straight to the dealer. The dealer "was unable to replicate the problem" and told me it was probably just a one-time "glitch." Approximately 1 1/2 weeks later, it happened again. I took it back to the dealer. The dealer stated that the computer showed error codes P0700 and P2817, both of which are faulty transmission codes. The dealer stated that the technician cleared the codes, drove the vehicle, and was once again "unable to replicate the problem." The dealer stated that it was going to request assistance from Chevy's engineers because it could not figure out what was wrong with the vehicle. I don't believe the vehicle is safe to drive at this point, as I narrowly avoided being in an accident on two occasions within 1 1/2 weeks of each other due to the failure of the vehicle's transmission to work appropriately.

  I have had multiple instances where the "infotainment" center as well as electronic components on my dash have shut down completely while driving. The truck stays running while it does this. The electronics then take a few minutes to "reboot" and then return to normal. I have had my truck to the dealership twice for this issue and I was told they did not find a problem and could not replicate it. I also contacted Chevrolet and they simply recommended I take it to a dealership to be evaluated.

There were no warning lights illuminated. The vehicle was not taken to be diagnosed or repaired. The dealer was informed of the failure.

• 08/05/2026· AIR BAGS,SEAT BELTS

  We bought this truck from a dealer (used) and before delivery the driver seat belt recall was repaired as it was still open. Now, months later, the airbag light is on with a warning and it appears that the airbags are disabled. This started as an intermittent issue and now remains constant. Not only does the warning chime when the truck is started, it will chime at random while driving which is a distraction and a significant safety concern for our young adult driver. Our local Chevy dealer will not assess the issue for less than $300. Our mechanic told us that replacing the airbag is a minimum of $800 depending on the extent of the work. Given the prior airbag recalls impacting Chevy/GMC, I thought this is important to report in case others are seeing airbag warning issues in a more widespread issue. As airbags are such a large part of automotive safety these days, I truly believe that these issues should be checked out at no cost to the consumer. Airbags should not be something that breaks down with normal wear and tear and should be a longstanding safety feature of the vehicle. Malfunction is likely a defect, not a result of normal use.

  While driving downhill nearing a stop sign my wife went to apply the brakes to stop and all she had was an extremely hard brake pedal. She panicked that she “no brakes.” She was only going about 20 MPH, and was able to stop the vehicle but it took an extraordinary amount of effort to do so. Had she had to make a sudden stop for a child, another person, or something else, she would not have been able to stop without negative consequences including possible death. There were no warning signs, vehicle pulled out of driveway and brakes were normal. Less than 10 seconds later no more power brakes. The vehicle had the vacuum pump seize which eliminated the power boost and the pump is operated by the exhaust camshaft which also got damaged and needs replaced. Chevy dealership estimated the repair at $2,600. Upon researching the vacuum pump, this is a common failure on multiple GM vehicles resulting in sudden brake loss. The vacuum pump should have been designed with a shear pin, so that if it fails the camshaft does not get damaged. Had the vacuum pump been properly designed and it was the only failing part, the repair cost would be $500 versus $2,600. Also, there should have been a temporary backup system so you would not lose power boost.

  While driving on the parkway, the engine revved, and then the brakes became hard as a brick. The truck was unable to be stopped. There were no warning lamps or indications there was a problem, it happened suddenly and immediately. Other drivers' and my own safety was at risk because I could not stop the truck. Here is the diagnosis from the GM service center where it was towed to: "After the removal of the valve cover, the tech found the pump in pieces, and the end of the exhaust camshaft was damaged, as presented in the photos. The quote attached depicts all that is being replaced with this repair." The is a know and acknowledged GM defect that has affected well over 3 million vehicles to date. There was a recall issued for some models, but not the Chevrolet Colorado. There are many reports online of other Colorado owners having the exact brake vacuum pump failure, resulting in damage to the camshaft.There is also a class action lawsuit filed in Michigan in early 2026, involving the same brake vacuum pump failure, for some of the models that were not included in the recall.

  I am reporting a serious safety defect involving my 2021 Chevrolet vehicle. While driving, multiple warnings appeared including “Service Power Steering,” “Steering Assist is Reduced,” “Service ESC,” and “Service Battery Charging System.” The vehicle then lost steering assist, braking performance became unreliable, and it created a serious risk of crash. The vehicle later shut down completely and has remained inoperable. The failure appears electrical and affected multiple critical systems at once, suggesting a cascading system malfunction. Since the incident, the vehicle has not restarted or operated normally. I have replaced the battery, alternator, starter, ignition switch, brake vacuum pump, ECM, spark plugs, fuses, and relays, but the issue persists. The vehicle still shows charging system faults and severe battery drain, indicating an unresolved underlying electrical defect. I have found numerous reports from other 2021 Chevrolet owners describing nearly identical failures, including sudden loss of power steering assist, ESC warnings, charging system failures, battery drain, and complete vehicle shutdowns. This suggests a possible widespread defect affecting this model year. Given the loss of steering assist, braking irregularities, and full vehicle shutdown while driving, I request NHTSA investigate this issue for a potential safety-related defect and determine whether a recall or manufacturer action is necessary.

  Steering becomes extremely stiff after 20 min at highway speeds. The problem only happens during highway speeds. Steering will "stick" and when wanting to change lanes or avoid a rough spot or hazard. You have to jerk the steering wheel to break it loose. Often, the effort required causes overcorrection, and you need to re-correct the wheel back suddenly. Even passengers notice the over steering required to change lanes. It doesn't feel very safe and my warranty ran out on time 2/11/24, not mileage. Researching the issue it appears there are many owners of the Chevrolet Colorado experiencing the same steering issue. The vehicle is a 2021 Chevy Colorado with 30,250 miles and very well maintained. I do have an extended warranty but they do not cover the repair/issue due to the power steering is electronic.

  There was a catastrophic engine failure of a 2021 Colorado 3.6L V6 engine. The engine has been replaced by GM and the failed engine is in the dealers' possession. While driving on a congested street, the engine misfired and immediately stopped. The vehicle rolled to a stop in the middle of 3 lanes. Occupants had to flag down traffic while pushing vehicle to the side. There was no warning lamps, messages or other symptoms, such as knocking, prior to the failure; and the oil service was maintained per manufacturer. Two separate dealers found "piston to valve contact, top of piston severely damaged, and metalic debris in intake plenum." GM Service Bulletin 19-NA-256 has identified "Seized engine" caused by defective "crankshaft main or rod bearing failure" that can put the oil filter "in by-pass and distribute unfiltered oil with bearing debris throughout the engine." In addition to the rod bearings, designated inspection points are the cam caps and camshaft journals on the heads and the timing change idler sprocket for stiffness when turning. Since the vehicle was 15,000 miles over the 60K warranty, they would not perform the designated diagnostic steps in Service Bulletin. Owner waiting on independent oil analysis. Service department provided pictures of metallic debris and valve damage, as well as the damaged spark plug. After opening Case # 9-14977425869 with GM Customer Service and asking why Warranty has not been extended or a Recall issued for the known manufacturer defect in the TSB, the response was "it likely has not occurred enough times to warrant a recall". With a dealer discount, total towing, diagnostic and repair costs exceed $11,000. Results of Blackstone Labs oil analysis will be provided when completed, however, the oil was just changed 462 miles prior to the failure, so a sample of the previous oil that would have contributed the most to the failure was not available (6,948 mi on previous oil).
