BREAKING: GM is officially recalling the L87

[Scarey]

You can bet that GM has people monitoring all GM forums to see what is being said about this engine catastrophe and GM name.

I’m guessing not. Too big and arrogant. It took the federal government to get them to address a problem that they’ve known about for years. Too bad they squandered so much good will. They will never get it back.

The engine build date code is on a paper sticker on the rear of the driver side cylinder head.

We are more worried about the engine build date, not the engine block casting/build date.

The engine build date is for the full assembly, not just the engine block. It is what helps with the bearing and crank problems the L87 is having.

The engine build date is a Julian date that preceded by a capital letter and usually the number 1.

Earlier in this thread I believe there are pictures of the paper sticker and where the Julian date is located.

What would a 3 in the place of the 1 mean? Mine is K3 followed by 23

strictly for reliability nothing!
However, my 2024 high country is the first vehicle I had that has 360 HD cameras, adaptive cruise control, heated and ventilated seats, air suspension and magnetic ride, heads up display plus 420 hp and quad exhaust pipes. It rides like a luxury land yacht and puts a smile on my face when I hit the pedal!

I have experienced the benefits of all this stuff and don’t think I could ever go back! LOL!

That’s how I feel when I drive our 02 Yukon. It feels like a technological marvel and full of creature comforts compared to my 78/84. I guess it’s all perspective. I’m scared to drive our 2024 as I’m afraid I’m going to scratch or nick something.

PS: I think you are referring to the quad exhaust putting a smile, that’s badass indeed… I think the 8.1L will put a good smile for a 0-60 pull. It’s all about the torque!

I'd bet against that.

Forums are a virtually dead form of social media. While I still like them (because I'm old apparently), forums don't get anywhere near the coverage of tiktok, X, YouTube, snapchat, etc.

And,,, all those other forms of social media already have some pretty good data mining software built into them, so GM doesn't need people to monitor anything , they just pay the respective platform and all the data is instantly available (like ever hear about GM and LexisNexis, where GM was straight up selling customers OnStar data to LexisNexis, then LexisNesis would then sell it to insurance companies).

Not sure what the 2nd digit means. Many are #1. I am sure someone may chime in if they have any idea.

Bottom line and point being made is that GM (and most larger corps) probably *do* have some form of PR department internally that does monitor social media, from YouTube to TikTok and the archaic forum.. , for reasons not necessarily related to this recall.

But, no, i don’t think they (GM) would be monitoring forums or other media any more than they probably normally would be. It’s not like they actually care what people say on the internet, because people are idiots. Reasons for monitoring probably would be more in line with demographic insights and/or product marketing.

Not the L87 but probably very similar build and testing video.

Starting around the 6 minute mark Leak Testing and Cold testing checking over 12,000 test points! They must have missed at least 1 with the L87?

I would open up the drivers door and look down near the sill plate almost at the driver side rear door edge and you will find the build Month and Year X/YEAR listed directly on the tag.

Again a July start of build year would be rather unusual, I am not saying it does not happen, usually the only time the new model years do not start in Sept is when there is either a new model being released or a Mid Model Refresh.

Only way to confirmed the engine build date is looking at the tag on the rear of the drivers side cylinder head from under the car, it is not easy to see and if you have an AT4 or off road package usually skid plates

Mobil 1 FS 0W40 is Dexos R Rated according to this list, and is available at WalMart for around $25 in a 5 quart jug, and $7.99 in single quart bottles.

Thanks for the heads up. Picked up 3 jugs of the stuff and promptly changed my oil right away. Had just under 3k miles on the 0W-20 that was drained. Peace of mind until GM calls me for inspection on my L87.

I promise you that your not gonna get any kind of inspection. It better be making a noise or throwing a code. My dealership is NOT gonna tear engines down looking for problems.

When I was a kid I remember those STP oil treatment commercials. I had STP stickers on my school stuff and bike as I really wanted to be a motor head when I could eventually drive!

This one commercial had a muscle bound body builder and they dipped the tip of a flat blade screw driver in STP oil treatment. The guy grabbed the tip of the screw driver with his thumb and finger, flexed all his muscles and contorted his face. Every muscle in his body was bulging as he gripped with all the muscles he had. He tried with all his strength but could not hold the screw driver! That was the lubrication power of the amazing STP. Nothing could stop it.

Maybe that’s the solution to the 6.2l problem! STP oil treatment!
Going out tomorrow to search for this elixir and get my motor to last forever! Or at least until the new extended warranty lol!!!!

@23Seven

You just cut off the build month and year in the picture.

Just above the top right side of the QR code are 2 numbers/ 2 numbers

The first 2 numbers are the build Month, the next 2 numbers are the build Year

MM/YY

If the vehicle was built in July 2023 you would see 07/23
If the vehicle was built in July 2024 you would see 07/24

I would be very surprised any 2024 model year trucks would have been built in 07/23 but anything is possible.

I think he’s using the word that appears in various bulletins. If there isn’t some kind of inspection, then how are they going to determine who needs an engine and who just gets oil?

 

[viven44]

Inspection should include the following at a minimum
- Check engine oil pressure when fully hot with 0W-20 and compare with good reference
- Check for P0016 code / history
- Listen for valvetrain noise or other knocking noises
- Ideally look for low-level signals on other PCM parameters that can potentially show a drift if there is metal in the oil (misfires, and others similar to P0016 ? - still don't know how that code is set)
- Last but not least - drain 0W-20 oil and tear apart old filter and check for metal flakes

All of these are easy to do, and should be done at a minimum

Did you read the recall notes? Inspection doesn’t require an engine tear down lol.

I can almost guarantee you, even without reading it, that somewhere in the franchise agreement between GM (franchisor) and your dealership (franchisee) there is a clause that will require your dealership to perform the Manufacturer Safety Recall as written, or your dealership risks losing it's franchise. It has to be this way, else the manufacturer would have no way to affect any safety or product recall situation.

But my curiosity got the best of me..and I did an internet search for "GM Dealer Franchise Agreement", and low and behold, I found this document. Spent 5 minutes, scrolled to section 5.2, and right there, in plain txt, in section 5.2.3 and 5.24 it says:
"5.2.3 Dealer and General Motors will each provide the other with such
information and assistance as may reasonably be requested by the other to
facilitate compliance with applicable laws, regulations, investigations and
orders relating to Products.


5.2.4 To build and maintain consumer confidence in, and satisfaction
with, Dealer and General Motors, Dealer will comply with General Motors
procedures for the investigation and resolution of Product-related complaints."

And in section 7.1.3 it says:
" 7.1.3 CAMPAIGN INSPECTIONS AND CORRECTIONS

General Motors will notify Dealer of suspected unsatisfactory conditions on
Products and issue campaign instructions. Dealer agrees to inspect and correct
suspected unsatisfactory conditions on Products in accordance with the
instructions. Dealer will also determine that campaign inspections and
corrections have been made on new and used Motor Vehicles in its inventory prior
to sale, and follow-up on Products on which campaigns are outstanding

General Motors may ship, and Dealer agrees to accept, unordered parts and
materials required for campaigns. Upon campaign completion, Dealer will receive
credit for excess parts and materials so shipped if they are returned or
disposed of according to General Motors instructions."

Now, whether this is current agreement or something older, I can assure you GM would never remove the general intent of these clauses from it's franchise agreement.

I understand that but customers dont know how to interpret what they read. They assume that dealerships are gonna tear down every 6.2 built on the planet. Their will be protocols we have to go by before we even think about doing that. Like I said in an earlier post it took them 2-3 years to fix the takata airbag problem. This involves way too many more parts, people and money for this to come into fruition in 90 days.

 

[GMCnewbee]

Well, this thread has been informative and entertaining, but I think I have hit the saturation point. My 2022 Denali went in for an oil change at my Dealer Monday. Mileage 21,978 and 2,516 miles since my last change. 0W20 and no oil conditioner this time. My plan is to keep driving it and to keep changing the oil. I am under drivetrain warranty until February 2027. We will see what happens but I am thinking about a trade for a 2026 or 2027 if everything holds together until then. I will update the Forum, maybe a new thread "6.2 survivor"? or "6.2 lost it today".

Well I'm not one of those customers. So I understand what being entailed here.

The Takata air bag recall was a big problem becuase Takata had no way of producing that many air bags that quickly. There are still vehicles waiting for air bags. It is the biggest recall ever affecting many manufacturers besides GM.
