BREAKING: GM is officially recalling the L87

[Aggie76]

First letter arrived today. "Parts to repair your vehicle are not currently available" like so many others.

 

[tagexpcom]

Update: Got the recall letter for my 2021 Yukon 6.2L w/62K miles. Called the local GMC Dealership and after verifying my VIN they scheduled the PICO test this Wed. Didn't seem to be an issue other than they wanted to verify my VIN before agreeing to schedule.

Got the letter, had it in for a check engine light showing a misfire. Dealership unable to replicate the check engine light, performed the recall steps and it passed, this is a new engine with a build date of 4/25. Made it 22 miles and this is it now.

Does that recall letter say how long you have to bring your truck in for the inspection?

Thanks,

Ali.

It says "schedule inspection as soon as possible" but I think that's just because the tone of this this recall is a serious 'safety issue' if you loose you're engine.

Is this the first or second letter?

In my case - 'the first' letter which I got ~Jun 17, 2025. Here's a pic - https://www.tahoeyukonforum.com/thr...ecalling-the-l87.154084/page-157#post-1978510

Update: I received the recall notice (1st letter) for my 2023 Yukon 6.2L about two weeks ago (currently at 67K miles on its second engine. First died at 16K and was replaced in 2023).

I had the oil and filter changed at the dealership yesterday, but they couldn’t perform the updated oil replacement or required inspection—the vehicle isn’t yet on the official list.

I spoke with my service advisor (who has been great throughout this), and she confirmed the situation is a mess. The new oil formula is more of a temporary fix to buy time. The extended warranty helps cover failures in the short term, but if the vehicle experiences issues beyond the 150K-mile coverage, customers may be out of luck.

The major bottleneck appears to be engine availability. Even though GM’s engine plant is operating overtime, supply remains limited, so they’re releasing VINs gradually.

According to safety recall documentation (N252494002), if GM cannot complete the repair within 60 days of receiving the vehicle (assuming it fails), the customer may be eligible for a replacement vehicle or a refund (minus depreciation). In short, by staggering VIN releases, GM is trying to ensure they can meet the 60-day repair window and avoid triggering buybacks.

Thanks for the info!

A couple questions:

1) Where does it say this?
2) Isn’t N252494002 only applicable to vehicles in dealer inventory?

Page 4 of the May 2025 updated bulletin. The way myself (and my service rep) read this is........ If engine needs replacement, they shouldn’t let you leave with it. If they do and engine blows and causes an accident, that makes them liable for a lawsuit. So once identified the 60 day clock starts....which is why they are dragging out the VINs. They don't have the engines to do the repairs. So trickle the VINs over many months.



The US National Traffic and Motor Vehicle Safety Act provides that each vehicle that is subject to a recall of this type must be adequately repaired within a reasonable time after the customer has tendered it for repair. A failure to repair within sixty days after tender of a vehicle is prima facie evidence of failure to repair within a reasonable time. If the condition is not adequately repaired within a reasonable time, the customer may be entitled to an identical or reasonably equivalent vehicle at no charge or to a refund of the purchase price less a reasonable allowance for depreciation. To avoid having to provide these burdensome remedies, every effort must be made to promptly schedule an appointment with each customer and to repair their vehicle as soon as possible. In the recall notification letters, customers are told how to contact the US National Highway Traffic Safety Administration if the recall is not completed within a reasonable

time.

Completed the 6.2L recall today on my 2021 Yukon Denali with 62K miles.

One thing I didn't anticipate before taking it in is that if it fails the recall test and the dealer determines you 'need parts' (a.k.a. engine) then you can't get you're car back till they order/install 'the needed parts'. I asked what happens if I insisted I want my rig back and he said I could (possibly) sign a waiver and forfeit any benefit from the recall.

YIKES! I guess one needs to have a backup vehicle/plan in mind in case you're running engine fails the test?!? (My rig was/is running perfectly).

I did pass and got
1) New Oil Cap 0-40w
2) Owner's manual insert (8 1/2 x 11 piece of printed paper)
3) Oil Change
4) And this is the invoice

@cjlewis,

Your problem may be very obvious based on my read on the recall, since your vehicle already had the engine replaced in 2023, the replacement engine build date would be before July 1, 2024, so per the recall, you get an engine, not even a Pico test!

So not sure I would be in such a big hurry to have the recall performed on your truck unless the dealer had an engine in inventory which they should not be doing. My understanding is the dealers are supposed to order engines on a needed basis. Not sure what the pipeline currently looks like. I would have the dealer inquire what the lead time on a replacement engine is prior to the recall and what the shop backlog is going to be.

This sucks all around, but at least your replacement engines has 51k miles on it, seems it make is past the 3 problem windows of failing: before the first oil change, failing somewhere between 12-24k miles and then failing somewhere in the 24-36k mile range.

Good luck.

Good to know that I better have a backup plan if it fails. Living 2.5 hours from the nearest GMC dealer (sold us the Yukon) will complicate this. Guess once we get the call we'll have to drive both the Yukon and my truck as backup.

Not surprised. Those engines probably don’t have enough bearings to begin with, lol

 

[the 18th letter]

Sounds like bearing manufacturers lost their mojo during COVID. How many suppliers are there?

You scored bro!
At 62k you are out of warranty but you got extended warranty and free oil change!

Yes it’s good to be prepared for plan B if the truck fails.
Personally I’d rather have your scenario as I don’t think an engine change by a dealer technician is a good option. No disrespect to those guys but I don’t think they have enough experience for engine swap on these highly complicated vehicles.

If you can’t drive the truck is there any plan for loaner truck while waiting on the engine change?
If it’s only a couple days that isn’t bad but more than a week is definitely a hardship

For the most part after this is over with the techs will have a very good handle on changing these engines and will make some large pay checks.

Update: I see that my GM/online VIN/recall list was updated to include the Engine test after 2 days. We don't plan to sell the rig or anything like that - so glad to put this in the rear view.

Anyone running an oil separator on their SUV?

1.) I have the Corsa unit.

2.) The last few times emptying the can I have paid particular attention to the oil (every month), and it does seem like there are some very small metallic-looking flake in the oil / can. I am guessing this is NOT normal? SUV has 23,406 miles.

3.) Have NOT performed the recall yet (have only received the first letter).

4.) For those of you with an oil separator... Is this something that you plan to take off before returning back for the recall work? Is it something that GMC could push back against?
