BREAKING: GM is officially recalling the L87

[OR VietVet]

Except the 6.2l GM's are now probably the ugly step child nobody wants to touch!

If I could find a rust free 2005 Yukon XL in good shape with under 150k miles I would probably buy these all day long!!!

Love the GMT800 series as well. Where are you at and how far would you travel for that XL?

My son has his learners permit and is eager to get as much drive time as possible. I’m increasingly uncomfortable with the idea of him behind the wheel of an L87-powered vehicle right now. Is this valid or an overreaction on my part?

Definitely not over reacting! If you’re on safe road at less than highway speed with little to no traffic you are probably fine.

However

“Loss of Propulsion” on highway at highway speeds increases the likelihood and danger.

Yes I care about spending stupid money on a truck
Yes I care about the inconvenience and downtime of recalled engine

But I am extremely pi$$ed about the potential injury or fatalities that might result from “Loss of Propulsion” at driving safely at the speed limit 70 mph on the highway!!!!!

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.

UPDATE -

Found a shop cloth with some greasy writing that blew out of the back of a 1955 Chevy Task Force, it had some clarity on the N252494002 TSB RCRIT-25V274-5347.pdf

Details subject to change, techs are almost as in the dark as we are. GM is operating need-to-know.

- The 002 TSB has not been publicly tied to VINs yet
- Dealers can check by motor serial.
- Letters go out June 9th.
- Those who've had replacement motors: if your VIN was on the N252494000 TSB and you meet the serial check in N252494002 you're slated for a new motor.
- Those who haven't had a replacement motor: the service manual hasn't been released yet, may involve a VIN/serial check and "noise test" (?)
- Repairs planned to begin after letters go out June 9
- Very high backorder expected for new motors (6+ weeks)
- Oil caps with "OW40" already have high backorders
- Dealers will require receiving the recall letter prior to bringing it in, or other favors...

 

[OR VietVet]

I am curious how many GM vehicle owners will now say they have had enough and will get rid of their entire GM inventory at home or at work, no matter what years, or will just get rid of anything newer than 2020 or get rid of just their 6.2 engine vehicles.

I am expecting some rants on here about doing what I asked about here.

IMO, GM got it right with the GMT800 series. Anything newer, again IMO, is buying trouble(s).

Anyone got a version of the 000 recall? It seems to be nonexistent on the interwebs now.

Honestly, I think the only way GM could restore my confidence at this point would be:
1) Cease all current production of vehicles w/ L87 6.2L
2) Deliver all that engine manufacturing capacity to parts and replacement engines until every single defective 6.2L in the field and putting customers and the general public in danger is repaired.
3) Resume production of vehicles with the 6.2

Would this be fun for GM? No
Would this be a bummer for those awaiting a new vehicle? Yes
Would this be appropriate for all owners who dropped large bags of money on earlier produced product? Yes
Would this be seen as a gesture to actually want to fix the problem for owners? Yes
Will GM do this? Not likely

For the moment it appears by 6.2l is outside the Recall window. Engine build date July 15, 2024. So I am a bit nervous but not totally beaten down, I realize others are not in my fortunate situation. I had about 10 false starts going after first 2022 models, then 2023 models and bailed as I was finding out things about the 6.2l as I went. I actually walked into a dealer an put my name and my offer on a 2023 CPO that the dealer rejected my offer, they never even called me back! Then I was 30 minutes to pulling into another dealer for a 2024 CPO and I bailed as I had just heard about the oversize lifter bores, while it was tied supposedly to the 2023 models, I was not trusting any of the info I was reading about the "problem window".

So I narrowed down on a New 2024 which I got a pretty good deal on and was not much more than the Used or CPO units. Before I drove the hour to the dealer, I had them take a picture of the build month and year of the units I had narrowed in on and pretty much negotiated the number before I showed up. My final units were all 8/2024 builds, so this was about as late as I could find, there may have been some 9/2024 units?? with the 2025 coming out in 10/24 as I recall.

Anyway, I got lucky, but it was because I just kept backing off/out because I had a bad feeling.

My 2024 will be getting a transmission valve body upgrade in the next 7-10 days depending on my schedule, all parts are here in hand. My 2024 has not been recalled for the valve body problems, but I have about a 90% feeling the 2024-2025 will be recalled for the rear wheel lock up as they are happening in the 2024-2025 models. My transmission seems ok, a few funny downshifts when the fluid temp is higher (160F) but I am not going to wait to become a victim, I am taking matters into my own hands at this point. This valve body mod along with an upgraded trans pan which holds an additional 1.5 quarts and has a magnetic drain plug will extended the life of the transmission and hopefully eliminate problems for me for quite some time.

Now wondering if my wife NEW engine is proper.

2022 denali - I had a bad engine (failed) replaced with a bad engine (bandaid-ed), now under recall and I'm hearing the replacement engines are going to have the same part number?? anyone heard similar?

 

[DunzoDenali]

I like your logic. It would be some reassurance that GM is trying to do the right thing.

I've been told all component coverage is non-transferable now. Sounds like they have no confidence, to me.

Probably not many, at least among the people with Tahoes/Suburbans. I've got a 2023 Suburban and there is really no alternative except the Expedition but when I was doing research (pre-purchase) I got an impression that Ford had a bunch of own issues so it's not significantly better quality-wise.

Edit: I purchased an extended warranty that should last me till 110k miles to mitigate quality issues.

They can’t recommend it for everybody because it would threaten their very complicated mpg fleet numbers. I’m guessing the 6.2s that under recall, recommend 0-40, anre excluded from messing with their fleet numbers. From all the forum dialog, utubes and gm recall recommendations it’s clear to me 0-40 is a better choice for my L87.

 

[cornicekurt]

Until someone (GM, really) can say that there is a "max mileage" failure threshold after which a '21-'24 6.2 is no longer in danger of failing, then I think that establishing a "failure rate" based only on the engines that have ALREADY failed -- as though no more will fail -- is short-sighted at best.

If it could be said that all of these failures occurred under 5000 miles, say, and that if you're beyond that mileage you're in the clear, then a lot fewer of us in this thread would be concerned. But, as far as I'm concerned, that "failure rate" is nothing more than "the current failure rate," and has the potential to grow wildly.

Agreed. The mileage on these failures is all over the place. They’ll either extend the warranty out to 150 replace all of the motors

 

[DunzoDenali]

That's a lot of unnecessary stuff. The fix is in now get it fixed. For those that didn't know now they know. Problems are always on the radar of manufacturers. Every warranty issue is documented and followed. They see patterns emerge. They than take action.

Theres no secret. Manufacturers would recall much quicker these days because it preserves brand reputation.

No one is hiding it takes data to act upon.

 

[Antonm]

Not that this thread hasn't already gone off the deep end,,, but its also possible the oversized lifter bore issue (GM has an engine replacement TSB for that one too on these same engines) is contributing to the situation.

The lifter bore issue is an oversized bore, that oversized bore bleeds off oil/ oil pressure from the oil supply galley and just drains it back to the oil pan. With the thin 0W20 oil more oil / oil pressure would bleed off through that oversized bore compared to a thicker 0W40 oil.

So with an oversized lifter bore less oil would be getting to the rod bearings and its not like there was lot of safety margin with 0W20 to begin with, but using a thicker oil would help this situation as well.

Maybe GM is using one band-aid to cover two wounds on the same engine,,, or,,, maybe all the oversized lifter bore engines have already failed and been replaced IDK. But as far as I know the oversized lifter bore issue was unique to the 6.2 and not shared with the 5.3 and it is the 6.2 that is having failures of pressurized oil supplied bearings.

I wish I liked any of the other large family haulers that can tow. I feel like none are reliable with the cafe stds discussed. I do have my dealer pricing a Tahoe with baby Duramax for me....If GM offered me a deal on a new one with Duramax I would take it. Especially to get me out of this crap and not have to worry about if it's safe to take my family on vacation this Summer with large boat in tow.

What would keep you from buying a GMT800 2500 series Suburban with a 6.0 or 8.1 engine?

 

[23Seven]

This is exactly what I wrote about: switching from 0-20 oil to 0-40 oil on your own will result in loss of warranty.

I called and the service advisor said that since my VIN is not yet showing for a recall that if I came down to pay $245 for an oil change they would in fact put 0W-40 in it. I asked about changing it on my own and he said to put 0W-40 in it. Any getting an oil change from a dealership own their own will get 0W-40 moving forward.
