BREAKING: GM is officially recalling the L87

[KMeloney]

Finally got the call this morning to set up my ‘24 Yukon for the test. Still no 2nd letter from GM but living in northern MN our mail service seems to always run slow so not surprised. Unfortunately my wife has the Yukon in Michigan visiting her family for the next couple weeks so have an appointment on the 22nd.

What was "the call"? I don't have a second letter yet, but I also don't expect a call from my dealership (neither the original one nor the closer one I've been using). Did your dealer call you? What did they say?

 

[KMeloney]

After having inexplicably disappeared from the app for me for a bit, the recall showed up for me again, and now there is a message that says “There is a Product Safety Recall for your 2023 Tahoe. Please schedule a service appointment to resolve the issue.”

I’m going to have to think now about when I want to take it in, and potentially (but unlikely) be without it for awhile if it fails the test.

My app also says this now. Do you think that's the app's equivalent of the "second letter?" Think that since the app now says this, that I can schedule the test now?

What if the dipstick itself is manufactured incorrectly?

What if the dipstick itself is manufactured incorrectly?

You clearly do not understand, dipstick or no dipstick, the dipstick is not the problem.

If these engines had no dipstick, I would have drained and measured the factory oil fill and MATCHED the factory oil fill on the engine when changing the oil. A dipstick is likely more accurate than an Oil Level Monitor. At least the newer BMW's with only a Oil Level Monitor and no dipstick requests you put the vehicle on a level surface, verifies the engine oil temperature, requests you put the vehicle in Park and leave the engine running, then the ECM/DME brings up a fast idle for a programmed period of time to verify the engine oil level. Many other vehicle manufacturers do not even try to have a consistent way for the Oil Level Monitor to verify the oil level.

Again, suggest everyone check their oil using their dipstick at the next oil change, whether you perform the oil change or not, and see if the oil level is only 1/3rd the way up the hash marks, or slightly lower. While some may consider this in the "Normal" operating range, it technically is, but he oil level is below the full operational point.

Somehow this concept of matching the factory oil fill level after verifying it on many other same model 2024-2025 vehicles to be the same, it only appears about 5% of the owners can grasp and understand the concept and realize there is a problem.

The posts on oil level might want to be moved to a new thread by a moderator that would deal with oil fill on 6.2 engine to clean up this thread.

That way any members doing a search could view.

Great suggestions -- let's do that and NOT litter this thread with that particular issue. It's well-documented in the other thread.

Yep! I never got a second letter (nor a call from the dealer, but wasn't expecting one either), but once it showed up in the app that I could schedule the inspection, I did so, and it's now been completed.

Thanks for the heads up! I just checked my App and there is was, loss of propulsion notice. I do not yet have the second letter. Interesting because I was just talking with two Service Departments last week and was told that my VIN was not yet released. I am going to make a call to my GMC Dealer and see if they are ready to schedule me. Will update when I find out.

Pretty much in the same position. Awaiting a call back from my service department...

FWIW, I scheduled my appointment directly through the app. Then, the service dept called me directly shortly thereafter to re-schedule my appt to the next business day, because I had scheduled it in the afternoon and they wanted me to drop it off in the morning instead. Regardless, for the inspection and the ECM software update, I was in and out in just over 2 hours.

 

[KMeloney]

Ok, I can confirm that the change in language in the app DOES appear to be the go-ahead to schedule the engine test despite not having gotten the 2nd letter. I take my truck in Friday.

Thanks for the heads-up on this!

Good luck. Which outcome are you hoping for?

I suppose a pass.

If we had been hearing of passed engines that got heavier oil failing, then I guess I’d be hoping for a new engine. lol It’s a conundrum, for sure. But I really like this truck, and I think passing and getting heavier oil will give me peace of mind.

Anyone noticing a slightly rough idle after passing the test? When I come to a stop, I can feel some type of movement by the engine like it wants to bog down. It’s extremely slight and nothing major so maybe it’s just me. But I feel this every 5 seconds. Possibly bad fuel? I’m taking the rig out of town so I can’t leave with a dealer but I’m wondering if it was the ECM flash.

Dealer recall specialist called me to set up an appointment for the test. I said I hadn't seen the second letter and she told me my VIN had been released by GM and I wouldn't need to get the letter. So I assume that the letter is probably "in the mail" and will eventually show up too. I had called and spoke with the recall person about a month ago and she had made a note (her words) of adding me to her list for this recall.

 

[KMeloney]

Well, my '23 Denali passed! Going to pick it up shortly.

...and then I'm going to put the K&N intake on it this weekend. Psyched!

You know, reading this thread, I have strange thoughts. I'll try to explain them. According to statistics, only 3-5% of owners have breakdowns. This means that the remaining 95-97% of owners have not experienced any breakdowns. Well, that's a big percentage.

I'm in the mindset that 95-97% with 'good engines' is the glass 95% full rather than 5% empty. My 2021 (passed a few months ago) is nearing 70K miles now and running well - love the rig and I'm not loosing any sleep over this!

But I have been curious if you-all think of this engine defect as catastrophic for the 5% but gradual for the 95% or just 5% affected - period. Or in other words, are all the 'good engines' more likely to fail earlier at say 120K when they could have gone 170k? or is it more likely the 95% are good to go as if no recall had taken place.

Only time will tell. There is no reason that a good engine shouldn't go 200K. I'm also starting to think, based on posts I'm seeing, that most of the engines that are going to fail have already done so. Just not seeing a lot of new failures here.
