Engine And Engine Cooling Problems of Chevrolet Colorado - part 1

The key does not release when in park! I have to adjust the steering wheel and gear shift multiple times to get it to release. 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!.

Immediately after braking in traffic or at a complete stop the there is hesitation with the accelerator. If I have to brake in traffic on the highway and then need to accelerate to enter another lane the vehicle will not accelerate for several seconds making it dangerous if the traffic in the other lane is traveling at a higher speed. At a stop sign when looking both ways to make sure the road is clear if I need to accelerate quickly the car will not move for several seconds no matter how far I push the accelerator. This almost led to a crash at a limited visibility intersection. I have not taken it to the dealer yet, but that is the next step.

The component that failed is the camshaft position actuator. My check engine light came on. Had my vvt solenoids replaced and the mechanic told me the actuator needs replacing. Gm has issued a special bulletin to fix this part for the same year make and model as my truck but my VIN doesn’t meet the criteria. I have only owned this vehicle for 8 months.

My 2019 Chevrolet Colorado, equipped with the 3. 6l lgz engine, recently triggered a p0024 diagnostic trouble code. This code indicates a failure of the bank 2 exhaust camshaft position actuator solenoid, a critical part of the variable valve timing (vvt) system. After researching, I discovered that general motors has issued special coverage n232430470 for this exact issue on the 2020 Chevrolet Colorado, which uses the same lgz engine and solenoid system. Despite the identical failure and engine design, my vehicle is not currently included in the coverage. I believe this reflects a systemic defect that affects multiple model years — not just 2020 — and that gm is choosing to limit coverage unfairly. This failure can result in check engine warnings, drivability issues, reduced fuel economy, and possibly emissions system non-compliance. I am requesting NHTSA to investigate whether this vvt solenoid issue warrants a broader recall or special coverage extension across model years with the lgz engine (including 2019).

On [xxx] after only 400 miles on the odometer, I experienced complete transmission failure while on a highway and was nearly hit by the vehicle behind me, luckily that did not happen. On April 29th, a new replacement transmission was installed by the chevy dealer, and now on [xxx] I had experienced a severe burning smell from under the hood of the vehicle accompanied with a grinding sound, which lead to me to take it back to the dealer. On 05/15/25, the customer care manager informed me that the new transmission from the factory has metal debris inside the pan, and the vehicle would again require a complete "tear down". This is very unsafe for major powertrain components from the gm factory to keep failing, another failed transmission on a brand new truck like this is very unsafe especially because I drive on major highways to commute for work and transport my young children. This is unsafe for the public and my family, gm needs to be held accountable, they also refuse to refund me my money back on this vehicle, and are disregarding lemon laws in nys.

Unknown. When my truck reaches a certain speed it is jumping or missing, it feels like a brake is sticking but I’m told it is a problem with my transmission, torque converter, going bad. It is getting worse. It cuts the power down on the vehicle. If I can go faster than 60 it doesn’t do it.

The problem started two months ago, with a loss of engine power and a stability track warning on the dashboard. This happened occasionally while driving, often going away on its own by turning off the vehicle. Two weeks ago, I took it to Chevrolet for an inspection. They did a general inspection and said it was a factory defect. Now, the vehicle has the problem constantly, and there are times when it's undriveable. That's a risk for me.

No warning lights or messages or anything. Blown head gasket and a large amount of coolant in the oil. I have an appointment to take it to a dealership the end of this week.

Upper radiator hose rubber grommet failing at 22k. Had a severe coolant leak coming from top radiator hose blowing back onto hot motor which could have turned into a fire quickly.

Vehicle component has been recalled on other Chevrolet vehicles manufactured during the same time just not this one yet.

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).

The manufacturer was made aware of the failure and referred to the NHTSA hotline to report the failure. The failure mileage was approximately 130,000.

Brand new truck… 2024 chevy Colorado lt 4x4. . Classic Chevrolet oklahoma city ok extremely rough idol, on cold engine start up, you can hear the rough noise it coming out of the exhaust and feel it in the cab of the truck. After warm up,, at intersections on red lights ,,you can hear and feel the idol miss at times a little bit. The dealership has had my truck for 8 days now. No positive results to date. They say gm is making them go through a step by step process. The service manager tells me there is a code in one of the cylinders. . But the injectors test perfect. Looking on google I see many owners of the same truck with the same issue !!!.

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.

I was driving down the highway going about 75mph in the left lane. The engine quickly started going down through the gears as the engine was shutting down. I was able to get it to the right side in very heavy traffic. I had to be towed. It took a 5 day repair and replacement of the fuel pump power control module. Warranty.

Drive ability issues, feels like going over cattle guard,shudders when accelerating around 40-60 mph. The vehicle shudder's abnormally. There are no warning lights illuminated. Took to local Chevrolet dealership where a service bulletin, TSB: 21-na-047 was discovered to address the issue. The dealer recommended a transmission fluid flush. Mileage on this vehicle was 67,631.

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. Towed vehicle to the dealership, where it was for 11 1/2 months with the determination it was the ecm and harness. Which it took that long to get. 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. Dealership now has vehicle and we have to wait for them to do a diagnostic.

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.
