The 2023 Chevy Colorado introduces the nameplate’s third generation, completely overhauling the midsize pickup with new styling, a new cabin, and a new powertrain. Unfortunately, some units of the 2023 Chevy Colorado may have been equipped with an engine that was produced with cracks. Now, General Motors has issued a new Customer Satisfaction Program to address this issue.
The new GM Customer Satisfaction Program is tagged as N232415060, Block Main Oil Gallery Hot Core Pin Casting Defect, and was released in February of the 2024 calendar year. The Customer Satisfaction Program only applies to the Chevy Colorado’s 2023 model year. It’s not clear how many units are affected.
According to the Customer Satisfaction Program, certain units of the 2023 Chevy Colorado may be equipped with an engine block that was produced with cracks. In order to fix this issue, dealers are instructed to replace the entire engine.
Update: according to a GM spokesperson who reached out to us following the publication of this article, there are only four Colorado units affected by this program, along with three Chevy Silverado units and seven GMC Sierra units.
All 2023 Chevy Colorado units are equipped with a turbocharged 2.7L I4 gasoline engine as standard. However, there are three specific iterations of the engine, each with differing specs and power levels. The entry-level engine is the Turbo 2.7L I4 L2R, which is rated at 237 horsepower at 5,600 rpm and 260 pound-feet of torque at 1,200, equipped as standard on WT and LT trim levels. The mid-range option is the Turbo Plus 2.7L I4 L3B, rated at 310 horsepower at 5,600 rpm and 391 pound-feet of torque at 2,000 rpm, equipped as standard on Trail Boss and Z71 trims and offered as optional for WT and LT. Finally, there’s the Turbo High-Output 2.7L I4 L3B gasoline engine, rated at 310 horsepower at 5,600 rpm and 430 pound-feet of torque at 3,000 rpm, equipped as standard on ZR2 and offered as optional on LT, Trail Boss, and Z71 trims.
The mid-range Turbo Plus 2.7L I4 L3B gasoline engine option was deleted for the 2024 model year.
All engine options mate to the second-gen GM eight-speed automatic transmission, while under the skin, the third-gen Chevy Colorado rides on the updated 31XX-2 platform. Vehicle production takes place at the GM Wentzville plant in Missouri.

Man it’s like Hitsville U.S.A. for the newborn twins. Can it get worse? As a customer who bought five brand new S-10 trucks starting in 1983, and four brand new Colorados, the last in 2019, this is genuinely painful to watch. My ’24 Trax is a very nice vehicle, but as a truck man at heart, where would I go to spend the kind of money these “small” trucks command in 2024 in order to get a quality product? Nissan Frontier remains the most honest and genuine, simple and true midsize truck available.
Every car make has its issues. Go buy your Toyota and find out
WHO said anything about a Toyota? I personally adhere to the idear the new Tacoma is ugly. But I am jealous of their extended cab availability.
yea, agreed. Getting rid of ex cab trim was a mistake. Not everyone needs a school bus with 4 doors.
Unbelievable! What about all of the 2.7’s that went into Silverados?
good question.
They’re included in the recall as well.
It is so sad, GM used to build high quality drive trains that would last a long time. Now they seem to build questionable engines, transmissions, and computer systems. GM needs new leadership now!
I’m having a hell of a problem with the trans on my 2015 Sierra, which GM knew about the problems but yet they let them go on the road. I very upset with GM, been and GM buyer all my life. I have developed a bad taste with GM. I so happen the have one of those lemons with the bad transmission, GM refuses to step up the plate and fix their ongoing problem.
Another Day in MaryLand .
Ive been a part of the team casting these blocks on the GM side. Ryobi also produces these blocks. I can say from first hand experience GM management will make operators run known defects and scrap just so the machines keep running. The casting quality of these blocks are very questionable and quality control isn’t what it was 5 to 10 years ago. Its sad
Can you elaborate on how this defect happened? What is a ‘hot core pin’? Does this cause an internal oil leak?
Core Pins are quite literally pins that stick out inside the die cavity where the aluminum is injected. So anywhere on the block that is to get drilled and tapped a core pin is there to help create more solid casting in that area after it’s machined. Several things could cause issues. Die being to hot in that area, die being to cool in that area, water leaking into the die during the aluminum injection process. The core pin being bent or broken. Casting are also sent out and get impregnated to help seal potential leak problems that cant be seen with the naked eye
You should post more. Good stuff.
Is Magnafluxing not done on the blocks?
Ever since Mary Barra took the helm this has become Garbage Motors it’s time to send her packing.
Seriously? When will the bad news stop?
Never. As long as products are built by humans (and that includes the robots we build to build the cars) things will continue to have defects. Until the robots are building the robots, this is part of the industrial age.
Years ago this would have happened and NO ONE would have known until their engine stopped working….heck, years ago this DID happen and none of us were the wiser….now GM is being proactive about it and STILL catching flak.
With all these ongoing issues, GM is making this pretty easy for 2024 Tacoma to take the top spot in the midsize truck segment.
Don’t think so. Watch TFL off road on the test on the snow covered hill against the Colorado. The TRD broke something in the drive shaft and became a 2 wheeler, had to be helped back down by the Colorado, pretty funny.
There’s a lot of issues out there that can be attributed to flukes or slightly incorrect tolerances. This ain’t one of them. This means there is a fundamental problem with how the block is made or the block isn’t strong enough for the engine. First the stop-order for faulty computers, now this.
I’m not surprised with the lack of quality in GM products. I have a 2019 Colorado, it was sold with the wrong transmission fluid. Just after 4 years old the seam sealer came off the door and it started to rust. GM wouldn’t stand behind their product, the Chevrolet service rep said it was an isolated case so they didn’t care and wouldn’t fix the failure. It seems quality isn’t a priority.
Poorly engineered fluid, not wrong fluid. The first 2 versions of Dexron HP were too hygroscopic, absorbed water and more than they should. The newest version fixed that issue.
So it was not the “wrong” fluid, you got a truck that was built on the tail end of the change over on the assembly lines to the newest fluid that fixed the concern.
I was a guinea pig for the first year of Dex-cool. Remember that fiasco? This was the mid 90s. Had alot of coolant problems with that S10. Getting a feeling of deja-vu.
Damn. It’s like every 2-3 months a new issue appears. Lol. Crazy….Chevy / GM think I’m made of money…?
Is this all 2023’s how do you know if yours has an issue ??
Every car make has its issues. Go buy your Toyota and find out
Keep excusing away poor GM quality gullible rob.
Diversity hires are running the show at GM!
After owning over 75 new GM vehicles, I’m 77 years old, my next vehicle shopping will be at my local Toyota dealer.
Mary Barra needs “CANNED”, period.
Maybe a position in the Biden administration with Mayor “PETE” would be a better place for her.
Only white men can build your cars? Why even go political with this issue? What a clown. It’s a casting defect (that shouldn’t have happened, but did). Irs not a diversity problem.
@james.. Diversity hires does not mean everyone except whites. Maybe you should check yourself before you wreck yourself.
Between GM, Ford and Stellantis, the Big 3 accounted for over 11 million vehicles being recalled last year. One thing all have in common, UAW labor. Certainly, some of these issues are engineering problems that should have been caught during the development process but weren’t. But many are manufacturing related where the UAW plays a huge role. Might want to make quality a central theme of the next round of negotiations, assuming any of these companies make it long enough to get to the next round of negotiation.
Might want to take your head out. UAW has 0 to do with No.1 problem “software issues”. And many of the vehicles, pieces parts and and “human failures” are coming from Mexico, South Korea and China.
Read the Window Sticker before you spill your guts.
the UAW just build what they are told to build and install what they are told to install. They have zero influence on where the parts come from. That is done at the bean counter level. Your pointing finger at wrong group.
But when you have to pay Union Labor wages you are forced to cut corners in other places….like engineering, R&D, quality control etc.
These engine’s were designed and built well over a year before any new labor agreements were made. Nice try though.
Why should you be forced to cut corners, so you can pay CEO’s and Board Members Millions more? Quality should not suffer due to wages. You are totally incorrect on that assumption.
GM made 14 Billion in profits in 2023. The 29 million CEO pay is pennys in a bucket. The execs said we want a 4 cylinder to replace the aging V6 engines. The 2.7 turbo is what thry cane up with. No corners were cut, just some bad castings made it through intio a few trucks.
I was commenting to Willy D about the cutting corners due to paying labor wages.
I own a 23′ Trail Boss, love the truck, however, on our second trip to the shop. 1st- a communication hub was defective, lost all screens. 2nd- last week, something went wrong, accelerating from a stop, large bang, kind of like I pulled a stump with a chain, rear end felt like I hit a huge pothole, and all the warning lights came on. Truck went into limp mode, went to slowly drive up a small hill, in a parking lot, and the tranny was slipping. I have not pulled heavy loads, at all, very little off road use, basically fields, to go hunting. Dealership has it now, but tranny guy is backed up, so I know nothing. 26,000 miles.
Holly Sh*t, I do not want a dealer replacing an entire engine.
I want a new truck!!
I got my 2023 ZR2 a few weeks ago (520mi) and they never cleaned the glue from the sliding rear window from a sticker removed. In no way do I trust the dealer with an engine replacement. I should have went with a Toyota.
Hey where is the engineer guy on here who was touting this 2.7L 4 popper as one tuff motor and way better than the 3.6 V6 IN EVERY WAY. 4 cylinders are the future and are great!! He is No where to be seen….LOL!!!
Probably took one of Mary’s “winning with simplicity” (aka cost cutting ) buyouts.
Hey, the topic was about a casting defect which can happen on any cylinder block with 4,6,8 cylinders. Part of the volume was outsourced to Ryobi, so it might not even be a GM produced casting. When you outsource vital parts you lose full control over quality.
I’ve have to agree with Kyle. These 2.7L motors were supposed to be soooo great. For the people that want a turbo and/or a 4 cyl, that is fine . Most people want a choice of motors. PERSONALLY I would like a new Canyon, but i probably won’t buy one unless I can get a 3.6L V6. Years ago, I wouldn’t buy the Colorado with the I5 motors either. Another engineering marvel !!
What has Barra been doing this last decade. Quality is obviously not a priority. GM needs new management
What about the 2023 GMC Canyon? Same engine, same factory.
I’d never own a 4 banger from GM! As has been touted before the 3.8 V-6 was one of the best built, I owned an ’86 Buick Park Avenue and drove it for many years trouble free of engine problems. I have an ’18 XT5 caddy, bought new with the 3.6 and its pretty peppy and reliable.
Last GM 4 cylinder I had was a 1976 Chevy Vega & only kept it about 10 months & swore never again.
What people see on GM Authority, ColoradoFans, and many Facebook pages are the whiners. Are there some isolated problems, you bet. But the far majority of Colorado owners don’t comment or even follow the pages after they get their trucks and things are going well. This includes me to an extent. I used to follow several forums, etc. but I haven’t had any issues since the battery-killing software issue last summer. Now I rarely get on a forum or comment since all you see on the forums are pissed-off people who use the forums to vent. The 2.7 engines have been out in the full sized trucks for a several years and have performed really well. I have a couple of family members with Silverado 2.7’s who were hesitant at first but are loving them. I had my 2.7 Colorado Trailboss upgraded to the new software which keeps the truck from disconnecting from on line updates, I also had it upgraded from the “plus” option to the high-output option. Finally, I had the reinforcing panels added into the roof. That has been the extent of the “bad” things. The ride, fit, finish, etc. has been fantastic. Anyway, just wanted to add something positive to the comments. FYI, I had a good friend who went from a Nissan Frontier to a Toyota Tundra in 2023. He has had a number of issues and recalls with the Toyota and his truck has been in the shop 6 times since last May. With all the ridiculous technology in these trucks ALL companies are having issues. I just wish Chevy, Toyota, Ford, Nissan, etc. would LISTEN TO THE PEOPLE and put out a truck without most of the electronics that they all seem to have. Hell, I wanted crank windows, no “infotainment” screen, and a manual key to start my truck. But some engineers somewhere think all this electronic CRAP sells trucks. To me it deters many people, including myself. I have Trailboss and its about as stripped down as you can get, but I doubt I’d use 90% of the electronic CRAP that is on my truck. Give me a manual 4 wheel drive shift lever, give me an old-fashioned radio. You get what I’m saying?
Yup that’s why I’ve decided to keep my 2012 Silverado instead of buying a new one. My 12 just turned 90k miles and still looks and runs great. I bought it new and it’s only been back to the dealer once for the airbag recall. I don’t think that a new truck will be as good as this one. Like you I don’t want the gadgets, this one has a real key and crank windows, it’s my daily driver and I love it!
Was the reinforcement straps that you had installed part of a warranty that you used? I’m curious because every time I go through a car wash there is a huge bang from the roof area. I also did the software updates for the motor to the high output and other than using 2 quarts of oil per oil change really the only complaints I would have about my trail boss and the 2.7 motor. Scheduled a oil consumption test with my local dealership to try to figure out why I am burning 2 quarts of oil every 6000 miles on a truck that only has 16,000 miles on it
4 Clys, go back decades. How ’bout the Vega 4 banger. Any one remmber those? Had two ’73 GT’s. One Kamback, and one coupe. Both blew the engines with less than 10,000 miles. Had one Hell of a time getting Chevy to part with new ones. One they did at dealer, the other we picked up and installed in my garage. I’m sure that couldn’t happen today. Yes, there are problems with many differatr engines. But, 4 bangers, seem to take the brunt of it. They seem to work twicw as hard as a V8. GM just doen’t get it. Forget 4 bangers. Just build real nice small block V8’s. It’s that simple.
Engines with issues. Software that doesn’t work. What a joke.
Every car make has its issues. Go buy your Toyota and find out
Keep up the good work, Mary .
GM, Mary Barra, all I can say is: WTF ??
I’d rather have IT issues with the Blazer than a cracked block that would require the dealership to swap out, & then having little issues under the hood pop up over they next few years.
I own a ’18 Sierra 1500 SLT crewcab 2wd and had thought about about a new Colorado. I think it’s a stylish truck. One of the best out there. But I’m not interested in a 4 cylinder truck, turbo or not. I would like a V6. Even an inline 6 would work. Then the interior. It’s a nice interior but not a fan of touch screens. Never have been. After a short time, it looks like a 3 year old was let loose inside unattended with all the fingerprints. And they are a big distraction. I like knobs, switches and the like. Like real gages, not facsimiles. Plus all the other electronic fluff. My truck has some but not as much as current offerings. Drove a ’23 Sierra Elevation. Just wasn’t feeling it. Since my truck is low miles(18,400), I’ll keep it. No issues with it and soon will install a Range Technologies AFM disabler. My point is vehicles in general are getting to be too much. Too much cost, tech, issues.
Two words……QUALITY CONTROL
Tough luck for the owners. When the time comes to sell or trade, the CARFAX will pick this up and down goes the value.
I am now starting to realize why Warren Buffet removed all his stock in GM. This company is a mess.
How do we find out if our 2023 Colorado has a cracked Engine block or not?
I went ahead and called the dealership and just simply asked if my truck was in it or not. They asked for the last 8 numbers of my VIN and then told me it was not in the issue.
Definitely get the fuel injector update. It is nothing more than a computer modification and takes about 30 minutes if that.
What happens if you don’t receive recall letter? Will they replace engine if something happens in a year or two? Also, if all Colorados were built in Wentzville, why are all not affected?
I took David’s advice and just called my dealership. After giving them my Vin #, they told me my truck was not on the list. But it was on the list for the fuel injector recall.
I just found out about this issue in my Colorado this past Friday. Was told the engines are on backorder so don’t have any idea how long it will be until I get it replaced. Sad!
