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 The engine has been replaced by gm and the failed engine is in the dealers' possession.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).

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.

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.

Engine light turned on. Fan keeps running for 10-15 minutes after truck is turned off. Went to two different mechanics and it is a thermostat problem. Temperature sensor and thermostat both have gone bad in under 5 years. They have told me it is not a good design and now parts are in back order. This needs a recall.

Upper radiator hoses are failing. Failed at 40k miles due to manufacturer defect of the part. Seeing owners complain about them leaking off the dealer lot and know 10+ that have had theirs fail around 30k miles.

07-01-23 vehicle died out, wouldn't start, got jumped, still wouldn't start. No indicator lights or warnings.

The vehicle was given back 06-14-24, even though it was in running condition, it was discovered parts were missing. Dealership put on order, received by end of July and installed. November 13, 2024, vehicle died out while driving on the freeway. Dashboard lit up everything, had to get the vehicle towed back to dealership. I have the onstar diagnostics indicating the same components as the original reason the vehicle was held for an approximate year.

I purchased my 2019 chevy Colorado z71 new in Feb 2019 from a dealership. About two years ago I began having shifting issues from 1st to 2nd gear, it would shudder and seem almost stuck, this would only occur infrequently. Right after I hit 100,000 miles (about a year ago) I have had nothing but issues with the 8 speed transmission, my vehicle is unable to shift from 1st to 2nd without having the shudder occur, it feels like the whole truck is shaking and loses power at acceleration. I took it in for their recommended "service bulletin" which was something that I had to locate myself because gm has not once communicated about there being any kind of shudder issue and they performed a simple flush of the transmission, not the service bulletin recommendation of three flushes and a different fluid. My truck is now in the shop because I am unable to drive it due to this ongoing issue that gm fails to recognize and so far have spent $1,000 attempting to rectify this issue and being told that in order for them to actually perform the service bulletin, it will be another $225 to diagnose the problem, around $500-$700 to perform the service bulletin, and then if that "does not fix the problem", I will have to spend another $900 on a torque converter because that "could" be the issue, the dealership "doesn't know". Then the third fix would be to replace the transmission ($5500-$8500) this has been a known issue since manufacturing and gm is failing to provide adequate assistance to fix a known problem with their 8 speed transmissions. I no longer feel safe to operate my chevy Colorado in fear that it could cause serious injury to myself and others due to gm not being able to provide a safe fix to their ongoing issue.

Check engine light appeared when starting vehicle. Code read by local auto parts store. Thermostat failed at less than 50k miles, causing fan to run constantly and for an extended period time after turning engine off, despite outside temperature. Causes potential for overheating due to not reading temperature. Thermostats are rated to last 100k miles. Is not covered under Chevrolet's 5 years/100k miles powertrain warranty. Upon research, this has been an extremely common issue for Colorado trucks for many years and has not been addressed by Chevrolet. Many blogs are available online. This vehicle was a certified vehicle bought just over 1 years ago and would not be fixed by any warranty according to the dealership purchased from (bob fisher).

No warning lights are illuminated but have this consistent violent engine rattle/shuddering that is getting worse and worse. Also when looking under the hood the crank pulley wobbles/rattles when truck is idle. Was told it could be the harmonic balancer going out due to there being a gap between that and the crank. The truck only has 100,000 miles on it. I got it used at 88,000 miles and have barely had the truck for a year now, the steering wheel was intermittently difficult to maneuver and no warning lights illuminate, the truck shifts hard from 1st to second gear now and seriously hesitates to accelerate. This is extremely concerning and apparently an ongoing complaint for this vehicle and something should be done about it. Not only does it cause financial destress on the owners of the vehicles but also a safety hazard to the driver.

The component that’s failing on my truck is the apple car play and a check engine light (code p0024) which indicates exhaust camshaft position, bank 2. My safety and others safety is put at risk while having these issues: 1. ) the apple car play, having to take my focus off of driving to try and unplug my phone and plug it back in to hopefully fix the issue of using the navigation or phone calls while I’m driving during long road trips is extremely dangerous for myself, my loved ones and others on the road around me. 2. ) this error code is extremely unsettling to experience while 500 miles away from home and has caused an incredible amount of stress on multiple occasions. The light constantly turns on and off, leaving me completely clueless as to if I’m going to be left stranded on the side of the road. Both issues have been looked at by an automotive repair shop. And I’ve been advised to seek information to if there are any recalls regarding this issue. Check engine lights display for the exhaust camshaft position bank 2.

The vehicle was purchased new from courtesy Chevrolet in san diego, CA. After 500 miles on the odometer, I decided to change the oil with fresh castrol syntec 5w-30 which has the dexos 1 gen3 approval along with a new acdelco pf66 oil filter. Upon removing the oil drain plug and after all of the oil had been drained, I noticed the threads for the oil drain plug appear to be loose and perhaps broken free from the stamped aluminum oil pan. Luckily, I was fortunate to obtain a perfect seal while pulling on the drain plug and threading it into the pan. The attached images are from a new oil pan I purchased. The steel threaded insert inside the stamped aluminum oil pan has broken free and the only way to properly repair it is to have the factory oil pan replaced with another. The design is poor and there is no way to prevent the threaded insert from falling into the pan rendering the vehicle inoperable. I will be taking the vehicle into the dealership to express my concern.

Temperature heater flap door, causes truck to go from normal temperature to red hot with boiling coolant in reservoir. Have spent thousands and thousands of dollars , on mechanics and parts! replaced water pump , thermostat, lots of cooling and heater parts and components . No luck and still no good running car , missing work and spending money we don’t have I read online about other trucks my same year and model having a recall on a temperature door. Causing it to overheat and a lot of people have had the same issue as I’m having. I looked up my truck. It doesn’t have it listed on the recall list but I’m sure that it’s the same issue.

The oil cooler lines are rusting and leaking. Seems to be a common issue going back 9 years since they started making these new Colorados from information I found online. Totally unacceptable for a truck to that is 4 years old to be rotting out. One of the lines is a nightmare to replace because of where it is inserted into the motor. Mechanic had to remove the front differential, axle, ac compressor, drive shaft, fuse box, and intake to replace a 60$ oil line.

The vehicle stuttered upon acceleration between 20mph and 35mph. After the 2018 chevy Colorado was taken into the chevy dealership for inspection, the torque converter failed at roughly 76,000 miles. A bad torque converter can potentially cause an accident. It can lead to engine revving issues, sudden speed changes, which can be dangerous while driving. The torque converter failed and left metal shavings in the transmission causing the transmission to need replaced as well. This was diagnosed by the chevy dealership and has a repair ticket of over thirteen thousand dollars. ( $13,000. 00 ) which most people can't afford to absorb. After a quick google search, this appears to be a common problem. There should be a recall to fix this issue.
