BREAKING: GM is officially recalling the L87

[22BlackDenali]

Here are images of the full GM N252494002 bulletin so this looks like the real deal, something will likely either be updated or posted on the NHTSA site next week.

In short vehicles with engines built BEFORE July 1, 2024 require an engine replacement.

For the guys aware of all the parts that should be changed in this scenario, does it look like everything is there? I see they did include the radiator. Anything missing?

The radiator really needs to be replaced due to the fact that it is clogged with chips from the wear of metal parts

Thanks for the GM Bulletin info. Just picked up my Yukon yesterday from a scheduled oil change. Dealer said they won't have any guidance until June, which aligns with what others have said here. For back ground, 2023 Yukon (purchased in winter 2022). Blown engine at 16K. On second engine. Have 61K on vehicle (45K on second engine). Invoice from the engine replacement in June of 2023 had a total cost of $14K (parts and labor). Plus $5K for my rental car. Took four months to complete. I have a feeling this is going to take 1-3 years unless GM dedicates production runs of engines to replacement vs new vehicles. Dealer had four SUVs waiting for engines already.

This guy is really scientific and detailed. Good video.

Several new docs with FAQ, messages to dealers, and all three bulletins are now posted on NHTSA.gov,

See Here https://www.nhtsa.gov/vehicle/2022/GMC/YUKON%2520XL/SUV/4WD#recalls

From My read, it looks like the 00 Recall identifed all in stock vehicles and told dealers to stop sale
The 01 Recall contained the inspection procedure
The 02 Recall summarizes the procedure for engine replacement for identified vehicles.

What is not clear is which recall any given individual owner is going to receive...but what I didn't see was a blanket "All 2021-2024 vehicles in the time period will receive a new engine." So, I think we all have to wait or inquire w/ our dealer do to an Investigate Vehicle History on our specific VIN to see which of the 3 recalls apply.

But, maybe I read it wrong.

For Kicks, I looked up my VIN, and it says the 00 Recall Applies rignt how and "Remedy Not Available" is listed. Meaning, I think at this time it needs an inspection, or that GM hasn't got around to deciding if 02 applies or not?

I also ran the vin that @StephenPT listed in post #16, and that VIN says it has the 02 recall, and it's status in incomplete (2nd attached file).

So, I would say keep an eye on your specific VIN's recall number...it will guide what remedy you get, I think.

Gm is extending the warranty on motors that just get an oil change to 0W40. 10yrs or 150,000 miles https://gmauthority.com/blog/2025/0...od-engines-to-get-extended-warranty-coverage/

Why would you carry a case of oil in your trunk?

Forever scarred from the time I pulled my dipstick at 40% OLM and it was bone dry, just before an 800 mile road trip. Looking back though, I was parked on a slight incline, with front the car facing down. I’m sure that impacted my dipstick reading. But was enough to illuminate my “low oil” light, which never lit up before my first blown motor at 3.6k miles. Oil in the trunk now as a constant reminder.

Just as I predicted......

Nose down on the truck would likely make the oil level slightly higher due to the dipstick being toward the front of the engine. I recommend checking the oil level at least every 2nd tank of fuel, which will equal around 750-1000 miles depending on how the vehicle is driven.

I think some of the higher mileage engine failures may be due to chronically running them low on oil. Often once the oil gets fuel diluted the oil thins out even more than will likely get consumed easier. Then the viscous circle starts, lower oil level takes less fuel to become diluted to a higher concentration, then the thinner oil protects less and is more likely to be consumed easier. Again a viscous circle.

Even if 0W40 shows no less wear metals in the engine, there are clearly some other reasons to run 0W40. Far more headroom or safety factor for fuel dilution, less likely to be consumed as fast as 0W20, many have made comments the engine is overall quieter engine operation and my main reason for running 0W40 is the extremely High Loading at Low RPM or lugging the 6.2l experiences while on the highway taking even the slightest grades. I want the extra oil film protecting the bearings under these conditions which the way I use my vehicle is quit common as most of my driving is highway.

I have logged this Low RPM (1500-1700)/High Engine Load (70-100%) behavior over and over where I am talking no more than a 50-100 foot rise over a mile distance. The TCM is configured to use a much torque on the 6.2l to keep the RPM's lower for fuel economy. Engine loading varies depending on factors, but 70-100% loading, sometimes slightly less if the transmission downshifts to 9th gear, but this is only about a 100 RPM change, you can barely perceive the transmission downshifts because the close gear ratio.

Note that the Reddit post says to refill the new engine (Line 3) with 0W20......
