BREAKING: GM is officially recalling the L87

[Scarey]

To my point, post #650 above , the info on oil viscosity is so blurred that there is no way gm would try a cheap shot to void a warranty for 0-40. Case closed, use either oil your comfortable with.

There will be nothing left to eat if you use a 223.

You’re not wrong there! .223 might be basically the same size bullet as a .22 but the big casing sends that little bugger down range 3x as fast. With that said I guess the difference in Mobile 1 European vs. Mobile 1 Supercar would be the same comparison of .223 vs. 5.56.

Is this going to be a new debate? LOL

You sure you 2024 was built in July 2023?? The typical model year change over starts in Sept. I think if you have a 2024 it was likely built in July 2024, which is on the edge.

First the discussion indicated any engine built on or after June 1, 2024 was fine, then they moved to July 1, 2024. If you have a July 2024 build, you MIGHT be outside of the July 1, 2024 engine build date. You would need to check the engine tag on the back of the driver side cylinder head for the Juilian Build Date.

My 2024 was built in 8/2024 and has an engine build date of July 15, 2024.

Checked the build date with the dealer by looking up VIN.

I've read through this entire thread and I didn't see much talk about holding GM accountable. Every person who bought a vehicle in this pool can show damages, even with the remedy in place. Resale value being the most obvious. There are safety implications of the highest degree as well.

I'm sure many of us use these vehicles as the primary road trip vehicle for their family. We now risk being stranded or worse ever time we take these vehicles on the road with our kids in tow, which is a complete mind f*ck. The amount of liability on their hands is astronomical. They've already admitted the potential ramifications of these defects.

All for giving them the opportunity to remedy this on their own, but I'm not holding my breath. Even then we will still have damages on resale.

Anyone know how we get involved/included in the class action lawsuit? That's the only solution I see. Most state Lemon Laws aren't applicable here. At least my state's wouldn't be.

I’m with you. How do we get on board!

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 are in the way.

If you haven't please read the FAQs about this oil viscosity straight from the horse's mouth

https://static.nhtsa.gov/odi/rcl/2025/RMISC-25V274-4725.pdf

"Why is the oil being changed in the vehicle?
The thicker viscosity oil offers an increased further level of protection."

GM has admitted that the thicker oil offers further protection (DFM, and everything included)

Let me state it again
"The thicker viscosity oil offers an increased further level of protection."

I would love for GM to deny anyone's warranty because they used 0W-40. Should be an interesting lawsuit.

Thanks. Been waiting for this to be published.

Left rear side
The date code on the 2024 6.2L engine can typically be found on the left rear side of the engine block, where the transmission mounts. The date code format is usually represented as "D 15 4," where "D" indicates the month (April), "15" is the day, and "4" is the year (1984)3. This code helps identify the manufacturing date of the engine block.

Actually I think that date documents the date of Assembly of the Engine, not the mfg date of the raw block.

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.

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