BREAKING: GM is officially recalling the L87

[Kaminski]

Do we have any GM techs on here that could give any updates?

Also, has anyone had their recall notice changed from the N252494000 to the N252494003 in either the NHTSA lookup or Chevy app?

 

[BADRIDES]

Inspection should include the following at a minimum
- Check engine oil pressure when fully hot with 0W-20 and compare with good reference
- Check for P0016 code / history
- Listen for valvetrain noise or other knocking noises
- Ideally look for low-level signals on other PCM parameters that can potentially show a drift if there is metal in the oil (misfires, and others similar to P0016 ? - still don't know how that code is set)
- Last but not least - drain 0W-20 oil and tear apart old filter and check for metal flakes

All of these are easy to do, and should be done at a minimum

Agreed

@23Seven

You just cut off the build month and year in the picture.

Just above the top right side of the QR code are 2 numbers/ 2 numbers

The first 2 numbers are the build Month, the next 2 numbers are the build Year

MM/YY

If the vehicle was built in July 2023 you would see 07/23
If the vehicle was built in July 2024 you would see 07/24

I would be very surprised any 2024 model year trucks would have been built in 07/23 but anything is possible.

So the build of the Tahoe was in fact July 2024… Now I need to figure out how to get my eyes on the engine build past skid plates underneath the Z71.

I spoke to the service manager at my local GMC dealer today. I was supposed to take my Yukon in on Saturday for the inspection and oil change and I got a text from him that said "GM has restricted the recall for now" and he said he was at a meeting in Indianapolis about the recall. Later in the day I spoke to him on the phone and he told me that GM was essentially dropping the recall and offering a 10 year, 150k mile warranty. I asked him if they are still offering the oil change and he said he would let me know.

He's not letting me bring the vehicle in for the recall, but I am due for an oil change anyway. Should I insist on the 0W40 oil? I want them to check the code history as well but that's basically the recall.

Well that’s fantastic. Just wait for them to grenade on the highway and kill our families. How is NHSTA letting them get away with this!?

This is a personal injury attorney gold mine! The driver/passenger with newer higher end vehicles most likely have insurance, the unfortunate collateral damage vehicles usually have insurance, GM has insurance and admitted liability with “Loss of Propulsion” statements and the NHTSA has the data. Policy limits are what the lawyers go for and that basket is full of easy money.

Unfortunately the casualties will start to increase and that is the real issue.

The TV commercials will start this summer and the big firms will have another big revenue stream

Funny, I mentioned the commercials a few days ago.......

The Z71/ZR2 and AT4's have skid plates that probably need to be removed. I have not been under one yet. You might be able to use a borescope camera to get a look at the tag.

My 2024 was built 08/24 and my engine build date is July 15, 2024. Your build is 07/24 you may be right on the edge. Early July vehicle builds probably have late June or early July engine build dates. Late July vehicle builds likely have engines built on or after July 1, 2024.

Best to get a look at the engine build date and hope it is July 1, 2014 or later

Good luck.

Just in case anyone was wondering....This is why insurance is so expensive....and not going to get cheaper, ever....

No disrespect, but I’m willing to bet that what he heard is wrong. It’s national news. GM is on the hot seat for over 600k L87 equipped vehicles. There’s no backing off on this especially with the NHTSA involved. I spoke to my service manager yesterday about the recall(he confirmed that my VIN was subject to it). Only that GM hasn’t released the recall to dealerships yet.

 

[Fast_AT4]

I called and the service advisor said that since my VIN is not yet showing for a recall that if I came down to pay $245 for an oil change they would in fact put 0W-40 in it. I asked about changing it on my own and he said to put 0W-40 in it. Any getting an oil change from a dealership own their own will get 0W-40 moving forward.

$240 for an oil change..damn, my buick/GMC dealership is $79.95 mostly w/a coupon <that I always have> or I think $99.95 w/o.

Old M5's was getting $350 @ BMW for oil changes.
Ford truck was $129 I think.

 

[23Seven]

Do oil changes myself for under $100 everytime! Takes 15 minutes instead of dropping off at dealer for 5 hours! With the adjustable air ride on the highest setting I slide right under.

0-40 Supercar oil that will be going into the 6.2 engines is $16 a quart holding 8 quarts and what ever they charge for labor plus if they rotate tires.

Hello everyone, a week ago I talked about my 6.2 engine with a mileage of 75,000 miles. On which we cut the filter every maintenance and there were no chips, no metal, no wear products in it. And yesterday my engine stopped. The oil was fresh, the mileage was about 1000 miles. Driving was on the highway at 95 mph, the oil pressure was high. So it was a highway, then there could be no fuel in the oil. The engine lost momentum and the car shut down completely at 95 mph, I stopped on the side of the road. I took out the oil dipstick, the level was full, but the dipstick was so hot that I immediately got a burn through the napkin. I think the oil was 200 degrees C. In general, I will tell you everything in a separate entry when we open the engine. And now our masters are confused, because this has never happened before, my case greatly violates many existing hypotheses. And about the connecting rod liners too, if they were to blame, there would have been chips earlier, and they were not there 1000 miles ago. Everything happened so quickly, without a rumble.

 

[viven44]

Sorry man that you had to go through this, yes please keep us posted on what you find. Did your vehicle set the P0016 code ?

Sorry man.

With your engine failing at 75,000 miles, it's that much more evident to me that the idea that there's "only a 3-5% failure rate" on these trucks is nonsense. There's no mileage after which you're "clear" of failure danger. I think GM is going to have to replace all of these engines in the '21-'24 range, and that the oil change will be a preemptive step on the way to engine replacement and NOT an option in lieu of replacement.

 

[KMeloney]

@Vladimir2306, with no GM support over there, what do you think your options are? Think you'll order an engine, or dump the truck, or what?

Wow @Vladimir2306, that is really bad. So sorry this happened to you. Looks like the inside of the oil filter is cooked, or is that metal sludge? Perhaps these rod liner's (bearings) fail catastrophically and very fast? That is the only part of your story consistent with the rest -- all is well until it is not well, then BOOM...no warning. Which, I believe, is the most dangerous part of this situation, as the user has no way to know if/when their engine may fail and they lose propulsion...

Damn dude.

Keep us posted.

That looks like an oil cooler was leaking internally. Not enough to drop pressure but enough to destroy your oil.

 

[viven44]

Vlad's top concern was voiding GM warranty... (not that it mattered to him being in Russia... it was a concern he had voiced nonetheless)

Something doesn't feel right about the fact that GM may void my warranty over the use of 5W-30 on my 5.3L.... it sounds like planned obsolescence....

I see grounds for some legal action to get GM's buy-in on 5W-30 or 0W-40 allowance across the board on 5.3L and 6.2L, following this recall.

This stuff is going down in front of us and don't feel good about sitting and doing nothing.

Anyone else?
