Here for this and apologies as this is on me. Had a '21 Yukon XL with the 3.0L. Nothing but issues (>100 days out of service) to the point where GM offered a significant "loyalty credit" in lieu of a buyback last year. Applied the GM credit to a CPO Escalade ESV with the 6.2L. Loved the Yukon more than the Caddy but we get far superior service and complimentary vehicles with the Caddy. Alas, the 6.2L recall has found us. The recall notice is now showing up in my Caddy app. Apologies to all for me owning your engine.

There has been a recall. Sucks for me and my 2020 which has an engine failure in February at 98k miles.

The problem was inferior metal compound used in the main bearing caps that would crack and eventually just let go. I understand there's a GM recall out for something like 800K plus vehicles with that engine and main bearing caps problem. Good luck GM......Corps_Ag12 said:tamuags08 said:Is there a fix that was implemented for 2025?Corps_Ag12 said:
It only affects 2019-2024 6.2L engines.
I think it's an upgraded engine design from the L87.
Also plenty of instances of manufacturers specifying the wrong oil for fuel standards. This has been an ongoing issue with BMWs since the early 2000s. Rod bearings are generally considered a maintenance item on a lot of M cars. BMW specs 10k OCI using 0w20 for my S63 engine, but I run 5w40 and 5k OCI to try and give a bit of buffer. They're specifying 0W20 in the US and 0W40/5W30 in rest of the world. That should say something.fixer said:Roger350 said:
The GM 6.2, the Toyota 3.5 TT, the Hyundai 2.4, why in the world are main bearings, rod bearings, and thrust bearings all of a sudden causing huge failures? These are the most basic of bottom end components for which designs have long been optimized and understood.
Is it the move to 0W20 oil in the search for 0.001 mpg fuel savings that is driving all these failures?
I've moved my 2 vehicles that call for 0w20 to 5w20, but wondering if 5w30 is the safest. Balancing that both are hybrids that can run on electric enough that "cold" or Luke warm starts are much more common I've been a little reluctant to go to 5w30.
I can't totally disagree…
However it is easy to dogpile on 0w20. But there are plenty of instances of the oil working well.

Victor Sheppard took 2 consecutive tundras to 1 million miles each.
He was on 10,000 mile oil changes with factory spec 0w20.
I think of bearing is designed for it you should be good.
The main bearing issues seem to be more related to lapses in manufacturing, possibly design in Toyota's case.
Motor Oil Geek put out a good video on this recall yesterday and goes into oil film strengths/viscosity.
Watching this video now. Came here to post it, and you beat me to it

How long do you want to ignore this user?

Does Japan still require engine replacement every 100k km (or whatever it is) to be able to keep it legal? They make cafe standards look like the wild West!1agswitchin4lanes said:BiggiesLX said:
0 weight oil is a U.S. construct and identical cars in other countries don't require it. Will companies redesign an engine to accommodate only US cars?I doubt it.
Change to 5w -30 and see how little your fuel economy changes. And 10k mile intervals are wrecking modern engines.
Japan is using 0w8 in some cars. And here too.
Passing this note along, we had our 2024 Yukon 6.2L in for service while the recall came out. When I picked it up, I asked the service advisor about it, and he told me GMC had no direction for them. They had been told by GMC a second recall notice would be coming out. As GMC worked thru a solution, it would be an individual recall based on the VIN. Seriously??....When I pressed him about that the number of individual recalls, 900k, he just shrugged his shoulders. It didn't make sense to him either.
What do y'all recommend using for a 2024 1500 Silverado Z71 with the 5.3? Its 4WD with the 10-Speed. I never tow anything. Mostly highway travel from home in Houston to work in Conroe. I do have the Range DFM/auto-stop module installed (RA007) thanks to TA.
And should we be changing it every 3K miles vs relying on the system alert?

Got a formal notice on the recall, taking ours in later this week. Will keep the group posted....
Repair Description
Dealers will inspect and, as necessary, replace the engine. Vehicles that pass inspection will be provided a higher viscosity oil, which will also require a new oil fill cap, an oil filter replacement, and an owner's manual insert.

Thanks for the update.
Just bought a 2019 Sierra 1500 with 6.2L from a family member. 95k miles and no issues thus far, has been meticulously maintained. Buying the Range Technologies AFM/DFM dongle right now and will be a hawk on 5k oil change intervals.
Seeing as how the 2019s are not part of the recall, like another poster on this thread, I am also researching a switch to 5w-30 oil going forward as a precaution.

2023 Chevy Suburban Premier w/ 6.2L - just turned 27K/miles - using Pennzoil Platinum 0W-20 w/ Dexos
No issues! Have not taken in to get fixed. Recall asking to fill with 0W-40
Seems like cheap way for GM not to pay fuel economy penalties at new car sales by factory filling with 0W-20 and just filling with 0W-40 service fill after the sale

Update.....everything checked out. Ours has about 25k miles. They performed a PicoScope Inspection (?), and everything passed. Changed oil/cap/filter.muleshoe said:

Not sure there is much else to pass on. Didn't sound like too many 6.2s had come in yet.
Hope you all have the same results!
I'm just liking the 10 year/150k mile warranty extension.

38K on my same-spec'd 23 Trail Boss. Still running 20 weight and changing every 5K miles. Had 27K on the clock when I bought it. Did an extended trip to Illinois and Wisconsin then back to B/CS and had zero issues.
I also have the Range module.

After watching the Dave's Auto video, it sounds like the thicker oil viscosity is attempting to maintain a better oil pressure through the chamfered holes on the crankshaft. Definitely some interesting stuff.

Is this the Range module that has to be installed under the wheel well, or have the updated it for the OBD port?
The old ones, used on the OBD port was easy to take on/off, but I held off getting the newer version since it was under the wheel well (from what I remember). I like to take it off when I'm taking it in to the dealership.
