BREAKING: GM is officially recalling the L87

[jfoj]

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:

Yukon Engine Failure - Buyback?

Have lots of questions if you would be willing to answer. Trying to get an understanding of the engine failures that occur after 7500 miles. If you would be willing to answer the following questions it would be helpdful. 1. What City/State do you live in? Need this info to understand the...

(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.)

Engine Bay Noise - Blown Engine

Alright, I have a noise coming from the engine bay of my vehicle (2022 6.2l Yukon Denali), I compare it to the sound of a baseball card or piece of cardboard flapping against a bike spoke (not a tick or ping). The sound follows RPM up to about 25-30MPH and then goes away. Also, if I rev it...

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.

 

[fredtufts]

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?

 

[jfoj]

@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?
