There are some failures out there. Just one forum may not cover this. I have seen them on other forums, Reddit and other places. The concern with the multi engine failures is the replacements were probably plagued with some of the same problems the original failures had.

Most were probably not configured with DFM and Auto Stop/Start bypass or low OCI, but each case is always a bit different. This is the crazy thing about the failures, were they really in a much smaller window, or was some crazy random stuff happening on and off for 2 years?

I know the member FredTufts has a 2024 Yukon XL Denali that is in the recall window with a 6.2l.

He bought the vehicle as a low mileage tradein at a Lincoln dealer with just around 2,400 miles. The Lincoln dealer changed the oil before it was sold, pretty sure they did what they said they did, then the oil was changed 2 more times before the engine failed at 13,000 miles. So 3 oil changes in under 13k miles! Even if the Lincoln dealer did not change the oil, his failed after 2 oil changes and at 13k miles.

As I told Fred, he did almost everything he could do right short of really going the distance with DFM and Auto Stop/Start bypass and a few other things but this may not have help him anyway. I mean 3 oil changes in 13k miles. He did get a chance to drive halfway across the country with the family without it leaving him stranded miles from home, so it did go the distance to a degree.

I believe he picked his vehicle yesterday, I need to follow up with him if he is back on the road.

I have yet to see an instance of a failure in this pseudo venn diagram:

greater than 5,000 miles, less than 90,000
2021-2024 range
Oil changed before 5000 miles, even with 0w20
Higher viscosity oil used, with any oil change interval, since first oil change
DFM disabled all or most of the time
Auto start stop disabled all or most of the time
Frequently driven more than 30 minutes in single instance

The closest (and it is very close) is Firetrout's 6.2 failure at 27,000 miles:


(I'm leaving out the engines that failed before first oil change. Those are something else entirely. Likely both debris and out of spec crankshaft or another failure mode (wrist pin?) that is statistically guaranteed to show up due to the volume of engines GM puts out.)
Double check w/ denalicountry...

Didn’t see that one had oil change information listed.

I will somewhat agree that if the engine failure did not happen before the first oil change and the vehicle is not used in more demanding situations (Towing, longer OCI, Drive It Like You Stole It, Bigger Tires) the chances or the reports of failures are lower. BUT I have seen a chunk of failures in the 15-35k range from memory.

I think everyone that is getting a replacement engine also NEEDS to have the DEALER take a picture of the engine tag on the rear drivers side cylinder head and provide you a copy. It should help understand whether the engine is new or reman and the build date which may be important. I would hope any remans that were built before July or Aug 2024 have already worked their way into vehicles, they may be the Take #2 failures.

The plot sickens!

If I am reading this correctly, then any engine BEFORE Juky 1, 2024 will need the engine replaced. This would mean that the vehicle builds that would likely need replacement engines would be built around 8/2024, but the engine date would be the governing factor.

I expect more to come.

Engine Build Julian date is on a tag on the engine itself, usually on the driver side, end toward the rear of the vehicle. Lots of posts online on where to find it...I had to stick my cell phone up there to find the build date.
However, I think the recall actually references the vehicle build date, not the engine one...but if you get a replacement engine, would be good to know it's build date.I ha
I have the serial number for my new engine replacement. Can I tell if it was new or remanufactured from the serial number and the build date?

@fredtufts

Look at that picture in the post a few before yours, #365 and the line that begins with K may be the "serial number"? The first letter may not be K but the next 2 numbers would likely be either 24 or 25.

You can either post it or PM it to me.

What is the build Month/Year on your Yukon? If it is after April 2024 this may get interesting.

I doubt if anyone who's engine failed in the less than 20K miles zone had really "abused" their vehicles... Prob had 3 or more oil changes of which one was free...

Who the hell wants to "baby" their vehicle just for the fear of it dying prematurely? If you can't drive it normally, (Kids, Dogs, Camping, Towing, Daily school trips,1500-mile vacations, short trip, long trip. etc) maintain it per the mfg. service manual standards and not expect to receive 100+k miles out of it, you flat out bought the wrong brand.

If you own this recalled vehicle, would you load it up tomorrow and take your family on a 3000-mile vacation? (I would have zero hesitation on mine...) If the answer is no, then you deserve more than a 0W-40 oil change.....
No one is saying “babying” their car. I said “take care of your car, it isn’t a race car” hell theres a dude on YT how has a 23 diesel xl that has over 150k already. If im not mistaken he’s in the transportation business. That dude takes care of his car.

183 is June 25? So that’s it, engine change? No bsing around, no engine code xyz, no change oil weight? Just plain and simple, change motor? Correct?

Yep. Too bad we're flat rate otherwise I'd be putting my kids through college with this BS.

The oil weight is a complete red herring. I've never seen one of these engines open with excessive wear that wasn't neglected. All on 0w20 per fleet contract. That said, I run 5w30 in my 5.3 to take advantage of savings since we have two others vehicles that take that weight. These engines aren't fragile and I know farmers around here that out of sheer laziness run 5w/15w40 diesel oil in them because that's what they have on hand. Not a great idea when it's cold as space outside but you can't tell them anything.

183rs day of 2024 is July 1, 2024. This means they would need to extend the 2024 model year cut off to Aug or possibly Sept if there were any 2024's built in Sept because of the mid model refresh.

I swear they're trying to get me with my July 15, 2024 engine build date. First you were good if the engine was built after Jun 1, 2024, now they move the goal post to July 1, 2024. One more move and I am in trouble.

As I read and re-read the info above in Post #365 carefully, this is my take on what was posted from the Reddit picture. If this is in fact correct and accurate, GM has done an about face. In short they have decided for the 2 year window of all the recalled vehicles, even if the engine has been replaced 1 or more times, if the engine has a build date before July 1, 2024 GM will be replacing the engine!! So engines all around, unless I misunderstood what I read. This appears that GM is taking the Toyota approach which is really the right thing, but for close to 750,000 vehicles or what ever the number is, this will sting bigtime, but this will also take years to get sorted. Enough engines and people to replace them are going to be a chore. On top of people that paid out of pocket for engine replacements that will likely get reimbursed.

Oh to be a fly on the wall in some of the GM meeting rooms over the past 6-12 months.

That was my point. There has to be millions of 5.3's out there post 2020 running on 0W20 in all sorts of conditions. I'm not seeing
the issues the 6.2's have. Which tells me the 0W40 is a band aid to cover up the actual defect. I would not be surprised if GM says switch to 0W40, puts a 10yr/120K warranty out there, cross their fingers and hope for the best.

My math, which had a bunch of assumptions which may be off a bit came up to $4,125,000,000.00!!!

Maybe they will not have 750,000 engines to replace, but I estimated around $5,500 per engine parts and about 20 hours labor which may be low?? About 20 hours dealer labor, last I saw was long block engine at around $2,500 which GM may have deflated?? But this will basically be at their cost anyway, and gaskets, fluids, freon, filters and so forth. Probably will need to replace the radiator and at least flush oil coolant lines. So my $5,500 may be low? DO NOT FORGET ABOUT THE RADIATOR GM!!! There is an oil cooler in there and you have no idea if it is partially contaminated at this point.

Maybe this would be more in the range of $7,500 per vehicle GM cost.

Since nobody will want to buy a GM vehicle after all of this bad press, the dealers will have a fleet of loaners while engines are getting replaced. This way the dealers will have a lot of "loaner" cars to sell at a discount.

All this will probably delayed due to engines in the supply chain and it will probably take close to 2 years to deal with this many vehicles given dealer man power and engine availability. So GM will not have to take the hit all at once.

Either way this will burn badly, then the transmission valve bodies are right around the corner.

I think anywhere and anything the oil flows to is going to be questionable. A vast majority of the long block will be replaced, and yes the engine oil cooler (if equipped) will need a good flush

Freon - R1234yf (that's a mess). Expensive job as the darn refrigerant costs ~8X of R134a. Anyway, here the AC compressor should just be unbolted from the engine. No need to evacuate or mess with the refrigerant.

This has the awful bearing (no pun intended) to the good ol' Oldsmobile diesel fiasco in the 1980s.


One Oldsmobile engineer who had worked on the V8 diesel told his bosses not to release the hastily developed engine. Needing to meet upcoming CAFE standards, GM forced him into early retirement and released the engine nonetheless.[2]

Dude you need to relax. Toyota just had a huge engine recall on tundras and most people don't know and don't care.

Most people won't break down from this. Most people will never have an issue. And Most people will get theirs fixed before any issues.

The fix is in. Step 1 is admitting the problem and now step 2 is correction.

You guys are going on and on about things you have no idea about.

I called my dealer this AM and they confirmed that my engine was on the bad list.. I said what now? The service guy responded that he did not know and that they did not have clear direction from GM. He said that they had been originally been directed to change the oil wait but now that plan was being scrapped.. Oh boy
My dealer told me the same thing. I am so frustrated! I think that I will trade the vehicle now before the value decreases.
