BREAKING: GM is officially recalling the L87

[JTGZ71]

Odd: I went into the GMC app today and my 2024 Yukon XL with the L87 engine no longer shows a recall. Huh. What’s with that?!? It had the first recall noted and I received the first letter in the mail.

Glad you posted this, because I’ve been seeing the same thing in the app. I will note though that the recall still appears when I check my vehicle on the GM website. So maybe just some issue currently in the app?

saw this on TikTok…not my video and not sure if it’s been posted already.

What is in the video? Couldn’t get it to play in Safari, and I don’t have/don’t want the TikTok app.

It plays in Firefox, no TikTok account or app needed. It's a quick overview of the PICO test.

[ … ] just had to move it to drive my 2024 GMC Yukon Denali to warm it up to change the oil.

When you did that change, did you put 8 or 9 qts of oil ?



And as far as the page counts are concerned, it’s not that complicated fellas. Looks like forum admins increased the post count per page from the abnormally low 10 posts per page, and that’s what reduced the page count for many threads.

He has said previously that he adds an extra quart........

I know. I think we should clarify that we are not abiding by the factory standards when giving out a multitude of tech about oil in these particular engines.

Yeah, my owners manual has a big warning about overfilling the engine with oil.

We're really not going down this road again, are we? Just use the dipstick to get and maintain the correct oil level for your vehicle. Yes, there will be some variations, depending on how much oil was removed. Don't be too concerned about absolute quantities, within reason.

Yes, “some variation”

You’ve missed the point of the post. All I’m saying is when reading information deriving from the internet, consider the source.

Right

Right

I didn't miss it, just didn't see the point of hashing out the levels all over again.

Just wanted to give an update. Into second week of waiting for a motor. Have the Hummer EV as long as I need it as a loner. The dealership does not seem to get any shipping updates as far as motors go. I got the results from the 0w40 oil analysis I did immediately before the failed test. This oil included some fairly aggressive towing of 7000 lbs for 15 hrs through hilly terrain on my family's summer vacation. Oil analysis came back perfect. Certainly doesn't look like the oil of a truck that was just condemned.

So it's fresh oil. What will happen to it after 2000 miles? even after towing.

I have a 2005 GMC Yukon Denali which I still drive daily (275,000 miles and counting), just had to move it to drive my 2024 GMC Yukon Denali to warm it up to change the oil. My 2024 6.2l Yukon is not within the Recall VIN range. The 6.2l in my Yukon was built July 15, 2024, 2 weeks outside of the recall cut off window. Does this mean I am in the safe zone, it should, but I do not run 0W20 oil in my engine, dumped it at 544 miles and never looking back. Additionally none of the 2024 6.2l have coated rod bearings, I cannot figure out 100% when the coated rod bearings were dropped, I am pretty sure the L86 had coated rod bearings but either with the start of the L87 or early on in the L87 manufacturing window the coated rod bearings were dropped.

I have a very negative view of most of the automotive industry these days. Not just GM but many of the manufacturers. Stupid decisions made daily, many may have started as wise, solid ideas, but by the time deadlines and dollars are questioned, things change quickly. Too many foolish ideas to try and obtain good fuel economy out of 6000 lb vehicles that impacts the drivetrain reliability. I doubt I will ever see anything as reliable as my 2005 6.0l Yukon, went into the dealer 1 time since new for a replacement NAV radio, al other repairs done by me and nothing crazy expensive, the engine and transmission have never been opened up.

When deadlines and dollars run the show, safety margins are tossed out. Does not really what Engineering thinks or wants, they get told to sit down and be quiet. I have seen this many times before and know it still goes on daily in many manufacturers. I have insiders in both US and Japanese manufacturers that I get info from on a regular basis. The Japanese are up against the same deadline and dollar problem as well.

Vehicles have become too expensive and the profit margins have shrunk for the manufacturer and dealers. Not much money made in new vehicles anymore.

Well aware of the crankshaft problems, it had to do with final journal finish which was not smooth enough for 0W20 engine oil. The thinner the engine oil, the smoother the crankshaft journals need to be. If theses engines still had coated rod bearings, the failure rate would be so much lower and there would not likely be a recall on these engines even with the crankshaft surface finish not being smooth enough.

As for safety margin, the reason GM is putting 0W40 in the recalled engines that "Passed" the Pico test is to give more safety margin for bearing life. GM really won't and did not spec 0W40 for replacement engines or the other non recalled engines because the vehicles were certified by the EPA with 0W20 oil AND if GM now pivoted and said all 6.2l and possible 5.3l engines should run 0W40 oil the lawsuits and reimbursements for failed engines that were not covered by warranty would be piling up and GM would likely go broke or at least be in serious trouble for years to come both financially and from buyers going elsewhere.

I am tired of hearing about ALL the MILLIONS of engines run fine on 0W20 oil, some do, but do the math for the bearing loading to see what oil these higher Torque engine should be running and it will not be 0W20.

While I dont like these new thinner oils it's not all an oil problem when these millions of engines do run 0W20 with no problem. If it was this recall would have happened 10 years ago. The 0W40 for the passed recall engines is purely a band aid to try to make them last past warranty with that part issue or at least look like they've done something.

This is one of the reasons I don't like newer vehicles. They do everything they can for that better fuel mileage and end up with more problems. Stuff like this, the cam/lifter issues that so many engines have now.

@MADDOG

I didn't get an email notification or a forum notification with the 11:20pm post, yesterday.

Has something changed on the forum backend, recently?

Are you subscribed to this thread?

 

[MADDOG]

Where would the posts per page setting be? I never changed that on my end. Also, I think a lot of posts would need to be deleted to remove close to 100 pages of a thread, so I don't think that's what happened. Personally, I did not change any settings that would alter the amount of posts I see per page.

The setting doesn't exist in this version of Xenforo.

I guess I wouldn't expect anything different from a synthetic with only 2000 miles on it. But you are right that the analysis looks good for a condemned engine.

I've gotten emails before. They all of a sudden stopped.

Edit- I unwatched the thread and 're-watched' but this time I set it to w/o email. It is possible that I had changed that option due to the amount of emails from when the debate were going back and forth. However, that doesn't explain the 100 pages missing.

Interesting. I'm not sure where almost 100 pages went. Did you see the post about my bookmark showing this thread in the 200+ pages and now we are at 109 pages?

Don't worry -- with all these posts that have nothing to do with the actual topic, we'll be back to 200+ pages in no time.
