BREAKING: GM is officially recalling the L87

[Marky Dissod]

Even if 0W40 manages to limp those L87s past 150,000 miles,
odds are against them making it to 200,000, or 250,000.

GM skrewered up here, big time. Only saying this once:
GM is trying to spend as little as possible, and to avoid spending any more as possible
(sounds redundant, until you think about it), and if y'all let them gt away with it,
they will.

This forum has an opportunity here, to make GM - which is not a person,
which will not hold itself accountable to ANY ONE of you if it can help it -
pay for a bunch of potentially faulty 6.2L L87s, one way or another.

Otherwise GM will get away with this, and try again, next time, with your kids.

Lake Speed Jr's latest video about 0W40 being a band-aid on a stupid failure is
pretty informative; too bad most of you won't fully understand -
some of you still won't even consider 0W40.

Not sure anyone knows the answer, however I'm confused. Is it inspect and look for that Pxxxx code and if found replace (if not just change the oil) or is it replace all engines that were built BEFORE 24183? And checking the "date" is the inspection.

You are not the only one confused.

GM has really screwed this entire thing up.

All I can say is first was the P0016 code inspection/Oil Change Recall without any extended Warranty.

Then there is press that GM will extend the Warranty to 10 years/150,000 miles on the "Oil Change" Recall engines.

Then there is the internal GM N252494002 release May 2025 which indicates, depending on your read, that any vehicle in the Recall VIN pool that has an original or replacement engine built before July 1, 2024 should have the engine replaced.

Depending on how you read the 4 page document it clearly indicates that everything in dealer inventory with an engine built before July 1, 2024 will get a replacement, but completely read Page 4. It pretty much says any customer that enters your facility for service the dealer is required to implement the Recall program correctly before releasing the vehicle.

So in general at the moment there appear to be conflicting information available.

How much more fun can we have?

The 1st few pages of this thread only about a week ago was SURE is was the thin oil.....

Not me check my initial response. Almost like I knew something.

See Post #463 above, bottom PDF line in that post, but you should check them all out.

Starting to think the 0W40 is an interim solution for complete engine replacements. With the numbers of engines that may need to be replaced, it could take 18-24 months for the bulk of them.

But read Page #4 of GM 252494002 CAREFULLY. Either someone did a horrible job of cutting/pasting and proof reading, or my take is all engines built before July 1, 2024 need to be replaced, not just for vehicles in the Dealer inventory. Even if this was the case with ONLY vehicles in Dealer inventory, this would leave all the current owners with 0W40 and now a 10 year/150,000 Warranty. This 10 year/150,000 mile engine Warranty from the date the vehicle was put into Service.

Pretty much a Parts Store battery replacement warranty from the original battery purchase. The original battery was Warranted for 3 years, but if you get replacement within the original 3 year period the replacement battery is only Warranted for the rest of the time left on the original battery 3 year Warranty, UNLESS you want to buy/pay for a Warranty!

The more you read, the more you??

The more you read, the more you ... ?

The more I read, the more I'm SUPPOSED to know ...
but sometimes the 'decode legalese' or 'decipher bullschidt' extension in my brain is not up to date,
and I wind up with more questions ...

In this case, my verdict is, any of you who does not figure out how to get (yet?) another L87 out of GM,
decided to miss out on GM's lapses in judgement on purpose.

Extended warranty on good engines

If that's true then it means no replacement for 100% of the engines in the recall window? So basically an inspection (whatever that entails to be seen I guess) and then replacing only the bad engines?

All I have to do say is "Lucy you got some splaining to do!"

Some may get it, others are probably too young!

IFF the engine goes bad before either too much time or too many miles have elapsed,
THEN you get a replacement.

I work at a Chevy dealership and all we have been told is that if your vehicle is in this recall then you will have to go to 0w-40 oil and the first one is for free then you are responsible for paying for 0-40 oil changes in the future which are gonna be more expensive than the 0-20. We did a Camaro Friday that was an 8 quart 0-40 oil change and it was $140 where a 0-20 would have been $88.

Sounds like the difference between using mobile 1 and gm’s dexos

You guessed it, Rod bearings !!

This is from a 2019. The Rod bearings do look like they have very high mileage on them, but this engine has less than 50K.

 

[Lonny]

Ok this appears to be a major development:

The “replace all engines built before a certain date” bulletin is now on the NHTSA website. Looks real, and looks like the oil change fix is no more.

Your missing key words in the document… “may”
They are looking for specific units, but obviously don’t know which parts went where went in which engine.

The ones that are deemed good today will get a special warranty for engine… 150k/10yr… really not an exciting recall, they are taking care of the defective internal parts

 

[Marky Dissod]

... really not an exciting recall, they are taking care of the defective internal parts.

GM's still trying to get away with as much as possible by spending as little as possible.
If your L87 makes it past 150,001, yet fails before 200,001 miles, it's definitely YOUR fault.

 

[Scarey]

I don’t see “may”. I see if the engine was built before 24183, identified as needing engine replacement.

This is from a 2019. The Rod bearings do look like they have very high mileage on them, but this engine has less than 50K.

Watched whole video. This guy does good teardown reviews. Seen a few of his before.

The varnish looks pretty bad for 50 k miles. This is a sign of oil degradation. The 6,000 mile oil changes that were listed may be one thing but did owner push it to 10k,or 15k once or twice?

The bearing wear also looks like a heavy load. Could be a degraded oil too. Is this also from DFM? start/stop (spending alot of time in boundary or mixed lubrication on the stribeck curve?)

Given the condition of the remaining bearings likely reflected the condition of the failed bearings, it wouldn't take much deviation off of spec on the journal to cause this--especially if the oil condition was sub-optimal.
