BREAKING: GM is officially recalling the L87

[KMeloney]

Only time will tell if just changing the engine oil is the panacea GM makes it out to be.

Not sure about that. If you get the thicker oil and your engine never blows, then you’ll never know if the thicker oil kept it from blowing, or it was never in danger to begin with.

It’ll be interesting (and not in a good way) if folks pass the test, get the new oil, and then have a failure.

I just got the news around 5pm eastern, that our 21 Yukon D needs a new engine 56,473 mi. Also had some noise at very low speed (like coming up the driveway). They said needs a new diff? I literally said to the advisor and I quote: “Hold your horses Buckaroo Bonsai, let’s cross one bridge at a time!” We both laughed at that. Anyway, I’m joining that club now Appreciate everyone here and thanks for the updates!

Was your truck in for the Pico test, or did it fail on the road recently?

If he says you need a new rear diff, let him do it. you are 3,627 miles from being out of your powertrain warranty, and the diff is part of the powertrain.

Thanks Mike, I’ve been researching my options. That would be huge if both are completely covered! Appreciate your help

Need to figure out the In Service date. 5 years/60,000 miles but if it is just beyond the time ask for coverage or partial coverage

 

[Blackcar]

Just throwing this out there the time your vehicle is at dealer for repair is added the months of warranty coverage if vehicle is at dealer for 2 months your warranty will be up in 5yr and 2 months unless you go over in mileage.

So I have been following this thread from the beginning and have a 2024 Tahoe with 6.2l, 12500 miles on the odometer now.

Still waiting for the second letter and every time I call the dealer about the inspection ( about twice a month) they say they will get back to me, don’t call us we will call you.

Ok, so it’s been several months since the recall notice. If it was for something less dangerous I can be patient but loss of propulsion is just an inoculos way of saying that you will have a serious crash at highway speed in traffic when your engine blows up!

Have there been any serious accidents from this “loss of propulsion”?
Anyone on this forum have any accidents or close calls?

 

[GMCnewbee]

Still waiting myself. My first letter is dated May 2025. I have not yet started to talk with my Dealer but I do have an oil change coming up so there will be a conversation. Mine is a 2022 Denali. Right now at 23,000 miles and I plan to take it in at 25,000. I'm retired so my miles come slowly. The good news is that so far everything seems to be working just fine. We took a 300 mile highway trip this week and burned less than half the tank. Amazing!

As far as what has been posted on this Forum, I recall a couple of really bad situations described as having to pull over in traffic, or getting stuck somewhere. I do not recall seeing anyone reporting having an accident.

My rig passed the test. (I still have my doubts about it) and found a few more recalls while in the shop and performed them.

23 Tahoe. 6.2. Engine failure on the highway last June at about 27k. Now coming up on 47k. Took 5 weeks for the new engine. Has been trouble free since. Going in for the test/engine replacement/warranty extension tomorrow. Honestly, at this point, all I care about is the extended warranty. It’s the wife’s car. She loves it. Typically she keeps cars 6-8 years and 100-120k miles. Happy to get the extended mileage on the warranty.

Admittedly, my story is 15 months old, but the dealer that we got towed to last year (330 miles from home) knew what the problem was before they had the truck off the rollback. They had heard the story before and seen “a few”.

Was driving 70 on a thankfully rural highway. Shut off, screen went black. Dead. Would have really sucked on I95 in the Northeast corridor, where we live and the wife typically drives with a car full of kids.

Good times.

 

[GMCnewbee]

Wow, thanks for sharing your story. Wife and I just finished a couple of 70mph trips on I-95 in Florida. I think that we are in the "Zone of Concern?" Our 2022 Denali now has 24k miles but everything seems just fine. I think I am going to call my Dealer right now. I do not have the second letter yet. I'll see what they have to say.

Let us know what the dealer says without the second letter. Mine told me that GM won't pay for the test and whatnot and won't officially acknowledge the outcome of the test (these are my words) without your VIN being released to have the test done.

I got the same response from my dealer on our '24 Denali XL so here we sit.

The Service Advisor at my Dealer was not sure(?). He looked up my VIN and I am not "on the list" but he did say that if I came in for service they would give me the 0W-40 oil. What I think he said was that he could give my engine the test. He was just not really sure about that. I also asked about failing the test. Would I have to leave the vehicle? He was not sure. I guess the news about getting the 0W-40 was good news. I need to be going in for Service in about another month or two. I will call again before I take it in. I am also going to call the Chevy Dealer who is closer to me than the GMC dealer.

As others have mentioned, I would not get the 0W40 until after they performed the pico test. It could alter the results.

 

[GMCnewbee]

Yes, you are correct and I had forgotten about that issue. Not sure I agree but it is something to think about. I guess what I really want is to get the test and the oil at my next service, which is coming up. Not too much to ask in my opinion. Service Advisor said that they are not doing tests because they do not have the parts (engines?) available to make the repair. That results in me continuing to drive. If I fail the test I guess they do not want me to drive? I'm going to go by the Chevy Dealer and see what they have to say.

I got my second letter and called my dealer to learn more about they have seen about the 3 per 100 failure rate now. I did inquire about loaner vehicle “if” my vehicle fails as I’m always hauling around 5-6 kids between sports. They said GM will only cover about $40/day in a rental and it has to be another GM vehicle through enterprise. This pisses me off if I’m going to be out of my car for any more than 1-2 days I’m severely impacted. That’s why I bought a 7 seater.

What’s everyone experience so far with this issue?

If you have to have your engine replaced, perhaps you could rent a larger vehicle and pay the difference with Enterprise?.

Not a cost-free or painless solution, but that would resolve your issue with needing a vehicle to transport the kids?

The engine replacement timeline seems to be about a week once scheduled, so the additional cost would not be great.

I understand your frustration - but sometimes we have to be resourceful and move on with what we have to deal with.

Best wishes.
