BREAKING: GM is officially recalling the L87

[jfoj]

If you have a 2025, I highly suggest you get on the 0W40 bandwagon sooner than later!

I got a notice of recall on my GMC app. Called my dealer to schedule the recall inspection. They said they are not ready because GM has not told them what the fix is if does not pass inspection. Told me to wait for letter in mail.....

It would be nice if they would also extend the warranty on the motor to 100k miles.

Agreed. Need some additional protection beyond current 60k powertrain

The document is a bit misleading. If they connect a scan tool and see P0016 they are supposed to "Quarantine" any unsold vehicles and mark them not for sale.

Have run my 2024 VIN multiple places and checked my GMC App a number of times, nothing. But I am not worried, I solved this problem at 500 miles and the oil has been changed in my engine 3 times and I did not even have 6000 miles on the truck.

I assume they might either tear down the engines with P0016 for cam or crank bearing inspection, but if a vehicle ends up with P0016, I assume they may just replace the engine??

Funny thing is, I have not seen any P0016 code problems preceding any engine failures.

The majority of the engine failures occurred at highway speed, typically between 60-75 MPH from what I have read.

GM 6.2l Engine Failure Fix!

@jfoj well done, you called the shots on this oil viscosity stuff accurately. I believe @Vladimir2306 should also chime in and let us what he thinks as his mind was very well made up on 0W-20... I saw the discussion over on the other thread discussing engine oil fill capacity.

I can relate to some aspects of this goof up from GM, as I deal with ridiculous politics. I am sure the engineers that designed and qualified this engine knew what was best for reliability. I'm sure the 0W-20 recommendation was the by-product of some stupid inter-company politics where the org responsible for emissions / economy came up with this 'fleet recommendation' and strong armed the engine dept...... From personal experience, all it takes for a technology company to ship garbage is a few bad apples who have been promoted high up in the technical and managerial ladder.

@jfoj I'm still going to ask you to not worry too much about the oil fill level as I don't see any recommendations in the recall for a new dipstick. Getting it at the max line when parked level, and periodically topping off to that level is good enough for the life of the engine.... Factory fill level as you have observed is probably garbage as well. Who knows if that is correct when they goofed up on the oil viscosity.......

GM’s notice of recall states (twice) that the recall should only be performed on vehicles in dealer inventory (only).

So lets watch this entire mess unfolds.

Are ONLY the 2021-2024 that are UNSOLD recalled?

What about all the 2021-2024 on the road? Maybe GM brokered a deal where they only will provide an oil fill cap, an adhesive note for the Owners Manual for the 2021-2024 models on the road, not even a free oil change to 0W40.

2025 Owners, GOOD LUCK!

Not all the rest of the owners use the same oil or drive or operate the vehicles under the same conditions.

The SINGLE BIGGEST threat to these engines is how the TCM is programmed to pull max torque at very low RPM's on the highway. How many of these engines failed at 70 MPH on the highway? Most of them.

The next BIGGEST THREAT is fuel dilution of the engine oil. Too many short drives in cold temps, too much use of the Remote Start to warm the engines up, too much engine idling for warm up from cold start. Too long between oil changes, sure follow the OLM, but you are a FOOL. Change the oil when the OLM hits 50%.

EVERY light duty and heavy truck on the road is in jeopardy of engine failures if they continue to use 0W20. Disable the Auto Stop/Start, disable the DFM. Then you are hopefully have something reliable. Otherwise you are gambling.

The NEXT GM fiasco unfolding is the valve body problems with 10 speed transmissions.

Just search my user name, you will find more than you care to read about the engine and valve body problems!

The recall is for trucks on the road, not just unsold inventory....

I foresee a big mess ahead..

hopefully the 6.2 owners will get some justice for GM’s poor business practices.. but it looks like it’s going to be more of a burden on the owners than anything else

Let’s see how this plays out

GM 6.2l Engine Failure Fix!

Mine failed at 30 mph FYI. Small sample size of course, but highway speeds may not always be the issue. It also states in the attached that they are to inspect the engine to determine if it needs replacing... unclear what that inspection protocol is.

GM’s notice of recall states (twice) that the recall should only be performed on vehicles in dealer inventory (only).

I got a recall notice that states my vehicle has a recall (even though I don't own it anymore). My buddy has the exact same spec Denali I had and he received the recall notice as well for his vehicle (both are 2022's). No where in the notifications does it say it's only for dealer inventory. However, I agree that it does say that if the vehicle is on the lot that they have to quarantine it and are not allowed to release it.
