General Motors recently launched a new Customer Satisfaction Program (CSP), numbered N232413430, specifically targeting a defect in the 6.2L V8 L87 gasoline engine equipped by certain units of the 2023 Chevy Silverado 1500, 2023 Chevy Tahoe, and 2023 Chevy Suburban. The CSP was released to address an issue concerning oversized lifter bores discovered in a subset of these vehicles. Affected vehicles will receive a replacement engine.
To note, the N232413430 initiative is considered a Customer Satisfaction Program, and not a recall. Currently, the specifics on how many units are affected by this CSP remain undisclosed. The CSP only affects certain units of the Chevy Silverado 1500, Chevy Tahoe, and Chevy Suburban produced specifically for the 2023 model year.
The affected engine, the 6.2L V8 L87, is offered as optional in several trims of the 2023 Chevy Silverado 1500, including RST, LT Trail Boss, and LTZ. The L87 is standard in 2023 Silverado 1500 ZR2 models. For the 2023 Tahoe and 2023 Suburban, the L87 is optional in RST, Z71, and Premier trims, and equipped as standard in High Country trims. For those driving an affected 2023-model-year vehicle equipped with this engine, GM’s CSP will involve a full engine replacement to correct the lifter bore issue. Vehicle owners affected by this CSP will be contacted directly with more information on how to proceed.
Introduced in the all-new, fourth-generation 2019 Chevy Silverado 1500 and 2019 GMC Sierra 1500, the L87 engine is a part of GM’s second-generation EcoTec3 engine family, serving as the direct successor the L86. Manufactured at GM’s Tonawanda plant in New York, the 6.2L L87 boasts 420 horsepower and 460 pound-feet of torque, and features an overhead valve (OHV) configuration, as well as Dynamic Fuel Management. Notably, the L87 engine was listed among Wards 10 Best Engines in 2018.

A CSP note vs. a full on recall on their top Silverado V8 engine for a crankcase lifter bore manufacturing defect with no info on how many units are affected? Unclear.
Particularly if the fix is an engine replacement. Both expensive and time consuming.
Sounds like this is an early issue alert. The GM Powertrain 5 year 100k warranty should apply.
I’m definitely very glad I decided not to buy a replacement ‘23 Silverado with the 6.2 engine.
When did the warranty go to 100,000 miles? I have a 2020 Silverado with the 6.2 and I thought the warranty was only 60,000 miles.
Bumper to bumper is 60. Powertrain has been 100K for over 2 decades. Your headlight falls under the 60K warranty. FYI, a wrong sized lifter bore will fail 20-30K miles. It’s a serious defect.
Only the 2.7 and the 3.0 have a 100K powertrain warranty.
2016 5 year and 60k warranty on powertrain.
There is NO 2.7L OR 3.O L engine in these TRUCK BODIES. WHAT VEHICLE ARE U TALKING ABOUT?
Yes, there is. Please check the Chevy website. There is a 2.7L TurboMax turbocharged 4 cyl abd a 3.0L turbocharged diesel. That’s what they’re talking about 🙂
Bumper to bumper is 36, not 60. Powertrain is 60 in most vehicles with some at 100. Only luxury brands have an extra year of bumper to bumper.
How can Ward’s declare the L87 a 10 Best in 2018 when the engine didn’t debut until the 2019 model year? Did you mean to say the L86 predecessor was Ward’s 10 Best? There isn’t much difference, except the L86 had AFM whereas the L87 has DFM. AFM only switched between V4 & V8. DFM has 17 different modes that suits down different cylinders and can run the engine on as few as 2 cylinders.
DFM was developed by a different company than the one that developed AFM.
I love my 17 Silverado with afm . Great gas milage, for a truck. 6.2 is nice, but better with a Whipple charger.
I change oil at 50% oil life or better.
It’s just a matter of time…..it will blow up.
No it will not.
My Bad Silverado ‘23 powertrain warranty is 5 Year 60k miles.
L86 was available on Silverado GMT K2XX truck platform ‘14-‘18. My ‘18 LTZ has an L86. Great truck.
L87 engine production began on the new Silverado GMT T1XX Truck Platform ‘19 to present.
Wonder why GMC trucks with L87 engines are not effected?
Just amazes me how these truck companies can’t build a simple truck anymore.
Not even Toyota. The new Tundra has engine failures left and right. Same with 3rd gen Tacoma.
Ever heard of the Titan? That has an N/A V8 with no DoD or auto start stop. And no, it does not have a CVT transmission.
I’m glad they’re addressing it, I’ve been seeing the 6.2s all over the internet with very low miles with engine failure, I was kinda waiting for them to figure it out.
Probably caught wind of a law firm putting together a class action lawsuit. Some owners are irate when GM tells dealers to only replace one bank of lifters when it stands to reason that if a lifter was defective, both banks probably have defective lifters from the same batch.
Why would this impact only the 6.2 on Silverado and not Sierra??? it’s the same engine. Are they just made at different plants?
It does impact GMC.
So no wonder I couldn’t find an engine to replace my High Country 6.2 V8. GM was hoarding them for this recall.
My 2023 Tahoe 6.2 was replaced three months ago with 13000 miles due to coolant in a couple cylinders. They blamed a bad block. Guess this is what it was.
I got the 2.7 2022 silverado and the dealership I got mine gave me a 20 year/200,000 warranty
Yeah, my dealership gave me Lifetime on Engine for 23 Sierra 6.2.
my dealer gave me a new vehicle warranty every 10 years for 30 years. Mileage unlimited.
These 6.2 have had this same issue since 2017 my 3rd one now
Hi, I have a 2023 Chevrolet Silverado LT 1500. I have a 5.3 l engine. So does this qualify for this truck? I like to know some information on this and do I need to call GMC if I wanna give in to this program..let me know
The AFM system is junk. I do realize this isn’t part of the 6.2L failure. Why in the world would they put that garbage on a performance engine. Heck it goes way back to 07.5 models and up and they still can’t get it right. It’s the reason I still have a 2003 2500hd with the 6.0
AFM doesn’t hold up well when owned by a 100iq person that waits until 0% oil life start thinking about scheduling an oil change. Or they short trip their truck daily and the engine oil is loaded with unburned fuel and soot, and stays there for 7000 or 10,000 miles. Fascinating how ExxonMobil put 520k miles on a 2015 Silverado 1500 with an AFM 5.3 engine and didn’t have a single lifter failure. A clue would be the fact that they didn’t do a cold weather short trip torture test that turned the oil into a fuel diluted mess.
I recently had to replace mine with 6600 miles on it. The truck was driving at 65 mph and turned off. Turned out to be this problem. Replacement motors were very scarce and I hope I didn’t get a motor with a defect in it. They tore my old one down and explained the same scenario to me. It was repaired within 2 weeks. I was told then that the motor locked up due to the parts jamming in it.
Fair enough, mechanical stuff has problems occasionally. It’s a nice truck.
FYI. Just announced on GM Authority that 6.2 L87 powered GMC Sierra, Yukons, etc. are also at risk for oversized lifter bore crankcases and possible engine replacement.
Still unclear why GM is doing a CSP note for the issue. Some quantity of L87 engines definitely were manufactured and assembled w/ out of spec lifter bores in the crankcase.
Has anyone had their 6.2 L87 engine replaced due to this oversized lifter bore issue or an engine failure due to same?
Appears that several 6.2 L87 engine owners have had engines replaced to date.
buy a tundra or have problems 1st gen 434,670 . I had a 16 silverado 2500 4×4 and 17 1500 4×4 .lemons at 89,654 and 94,097 . never again
The new Tundra with the engine that’s grenading left and right? LOL just about every Toyota influencer on youtube has had their engine blow up and some expressed their frustration with Toyota. Turns out Toyota thinks their engines are so great that even when thousands of them have grenades, they still act like the owner did something to cause it when the next one comes in with a broken engine.
And think about how much an owner has to shell out for a IFORCE 5.7L when that blows up….I have heard a 15k repair bill for those w/broken valve springs (and 6K for cam tower leaks…….. 2UZ can break pistons and it has happened- also a fatal issue).
I have a 23 High Country. Before I bought the truck I heard that it had the DFM system. I never heard of it until then. I heard about the issues with this system but decided to go ahead with the purchase. The smooth effortless power of this engine mated to the 10 speed transmission is breathtaking!! I change my oil every 3000 miles. That oil life monitor means nothing to me.
Good. Keep up on the oil changes and USE the right oil. DO NOT LISTEN TO the Internet.
Guessing they’re trying to find the bookends of the issue… Or already know what blocks are bad because they use data bolts for assembly for this very reason.
The “ vehicle owners will be contacted directly” statement tells me GM 1. Is keeping the total figure private or 2. Simply doesn’t know the exact numbers affected at this time.
Whatever the case it’s going to be an expensive fix per vehicle affected in materials and dealer labor.
Good luck and goodbye $40 per 100kms
Doing a bit of historical research a possible 826,646 GM vehicles built could be ordered with 6.2 L87 engines in ‘23 (Tahoe, Yukon, Suburban, Escalade, Silverado and Sierra Light Duty vehicles).
A conjectured ballpark of 10% built (likely high) with 6.2 L87 engines equates to approx. 82,000 vehicles.
It’s a guess from there how many are potentially affected.
I have heard some stories from 2024 MY suffering from this issue- but never heard of ANY issues like this in Qatar. I suspect it is better to use the correct oil and drive them properly from the start.
Going to start by saying I bought a brand new trail Boss that was a 2023 with the 62 I had less than 400 miles on it when my motor locked up
I need to say being one with the experience from GM remanufactured motor they put parts and they could have any anywhere from 1 mile to 200,000 miles on them my second motor less than 5,000 miles and it jumped out as soon as they put the next motor in I traded the truck in for a 24 Chevy Silverado 2500 HD 6.6 l gas with the 10-speed Allison transmission drove it out of the dealership 12 miles of home transmission was leaking they’ve replaced seals in this transmission now four times and that’s all they keep doing is replacing seals well had to go back to the shop yesterday once again transmission problems finally got them out of the lemon law it’s not just GM though all manufacturers now since covid hit it’s not about quality it’s about quantity.
However GM quality is the worst in the market

I got your point. As for your first truck, I suspect it may have been owner abuse.
No wonder abuse bonehead 12 miles on the truck and it was only abuse the f*** is wrong with you stop sticking up for GM GM’s totally junk
Something is wrong with YOU, not me. The owner is to blame if there is abuse, NOT THE MANUFACTURER.
It needs to be done by the “Engine Build Date” not by the vehicle Vin #. Sometimes engines are built and do no necessarily go into production vehicles immediately. So potentially a 2022 or 2024 can have the affected engine also. Example: 2024’s come out as early as Oct. of 2023. Brand new 2022’s were still rolling out in the early part of 2023 due to part shortages. I have a brand new 2024 Silverado RST Z71 with a build date of 1/24. I bet my motor was built in 2023. I will be most definitely looking for the build date tag on the back of my engine.
That is something I did not think about. But I suspect the manufacturer would be monitoring the process as to seeing any change in the failures. MY25 and MY26 are expected to be largely the same. The next generation will be MY27.
I bought a 2022 Chevrolet Suburban LT 2022 Chevy Suburban LT my engine blew up at 87,000 miles because of that was a lifter I believe so they asked me at the dealership too replace the engine because my warranty was 60,000 miles I spend $9,700 on the new engine and now I see this so this problem was before like I said my is 20/22 and I got a new engine on it cost me a lot of money and also right now I have a rear end problem you need to be replaced and the funny part nobody has the rear end available nobody in the whole country they all waiting for GMC too releases no ETA any suggestions out there for me thank you
Did you use the right oil? Did you change the oil on time?
Unclear if you purchased the vehicle new from a GM dealer. Usually a GM dealer you purchase from provides you with quality after sales customer support.
My GM dealer definitely does. In today’s electronic media world bad press can put a company out of business.
Doesn’t sound like you have a very good true customer supporting dealer.
If the failure was truly a manufacturing defect with the known problematic valve train resulting in a catastrophic engine failure it should have been covered or at least proportionally covered for a two year old vehicle no matter the mileage.
From the very first oil change maintenance tires rotation new tires everything is been done by the GMC Chevrolet dealer where I bought the truck with 0 miles nobody else has touched the car
Might be driving habits then.
Jose, I just had the same issue on my 2015, I went with a Jasper engine with the AFM delete option. GM has a big problem and will not admit their mistakes.
Maybe YOU did not take care of your truck.

My 2015 Silverado 5.3L with AFM, cylinder #8 intake lifter took a nap and destroyed my cam at 93k miles. New engine with out was installed, put a 11K hole in my bank account looking for a class action law suite.
That might be due to how it was driven. How frequently you changed the oil and what oil you used?
Am with you on this
I have a 2024 1500 RST 6.2L that the motor let go at 2500 miles… The dealership only said metal in the oil pan and they contacted GM and they authorized a brand new engine replacement. I do not want the same issues with the replacement engine that I had with mine… I asked how long and they told me a nationwide backorder for the 6.2L and NO ETA on a replacement engine. I heard there is a main journal machining tolerance issue on the Sialo Mexico built motors and GM is moving the machining back to US…any truth to this?
I just looked mine up. My ’23 1500 was built in Fort Wayne… so hopefully I dodged the bullet.
Does the first number of your Vin number start with a 1 or a 3? 1 is U.S. made and 3 is Mexico.
My ZR2 was a total engine catastrophic failure at 5000 mile. They are replacing the engine with the AFM/ DOD Delete Kit with new cam and Pro series Dual valve Oil Catch can new radiator and flash to the new sport mode that the 2024 got. GM said that dealerships are suppose to be calling all 2023 owner with Gen V L87 6.2L engines to schedule this replacement part before the engine fails.
where was is manufactured? The US or Mexico? Not that I doubt you, but is GM authorizing this or is it just your dealer doing this because you have a great relationship with them? Because I cannot see GM doing this. Again, if they are, then that is outstanding . Please keep everyone updated with details if you wouldn’t mind as this would be very helpful. Thanks
Just looked at my VIN…it was manufactured in the USA, so that doesn’t make me feel better. And yes, GM authorized the engine replacement along with extending the power train warranty.
I am in the middle of dealing with this right now. My 2023 Tahoe Z71 with a 6.2L completely shut down a few weeks ago, going 70 on the left lane of a very busy freeway interchange. I heard clicking for a bit but no warning lights and nothing seemed amiss, and within a minute or two the brakes fully failed (not just the power brakes… everything failed) and the electrical went minimal. I had to maneuver 5 lanes of traffic and coast to a stop. At some point as I was moving over it engaged neutral. Once it rolled to a stop, it put itself in park. Once in park, it would not disengage park, and so it took several tow trucks and several hours to get it loaded because neutral would not reengage and it was too large for the tow truck with dollies. According to the dealership, it will be 3-7 months for a new engine.
The best part? This is the second failure. The first was the battery 3 months in, and it lost the power brakes and steering on the highway making for minimal ability to control it, and it wouldn’t go above 42mph. Everything kept flashing inside like it was possessed. I’d pursue it as a lemon but I’d end up losing in the long-run with attorney fees and wasted time. I need a new vehicle because I can’t wait 7 months and basically am at their mercy hoping they help. I’ve called 3 times over the last few weeks and can’t get anyone at GM to call me back. Its been a nightmare.

How I will know if my truck is affect?
I called GM today(I have Silverado ZR2 2023) and they are not aware of anything.
Here a couple of links: https://static.nhtsa.gov/odi/tsbs/2022/MC-10212963-0001.pdf
https://gmauthority.com/blog/2021/08/how-gm-dealers-handle-engine-valve-lifter-issues/
This issue has been extended to 2023 and some 2024 models.
Do you happen have a link to a CSP or NHTSA document listing 2024’s also?
This is a problem that exists before. I have a 2022 Chevrolet suburban v8 5.3 last year at 87.000 k miles engine failure dealership tell me that new engine needs. Same dealership where a bought the vehicle and is service every time reason was the lifters .this is a 5.3 engine 2022 suburban but have Same issue as the 6.2 2023 suburban
I just went threw this csp & got my new engine installed in my 2023 high country was at the dealership for two days, the old engine had 14000 k/ms ran fine but noticed the oil pressure gauge dipped pretty low at idle & had a tick since day 1 with 20 km, new one has steady oil pressure & no tick so far, overall im satisfied with the whole process quick turnaround
