BREAKING: GM is officially recalling the L87

[viven44]

What if I’m wrong and it’s 20k to swap em all out which is what I’m thinking will ultimately happen

The ramifications are usually worse. Real world impact is probably that much. GM is going to replace 2~3 years worth of output on these engines, so they will need to double their manufacturing output on the 6.2s for the foreseeable future if they don't want to affect the new model production output (more capital expenditure, hire more operators, techs,...).. Its a big fat waste and hopefully teach them a lesson and slow down release of dumb new unproven technology. Dealers are going to be busy as heck as well, if you ask me the service department is going to be well funded.

I would imagine they’re going to get good at swapping them out before it’s all over. lol.

I do not know the exact way the GM OLM works but it looks at a number of parameters such as fuel usage, mileage, engine temp, time and maybe some other data inputs. So it probably flaga at the 1 year mark, I know it flaga on an engine overheating.

But th 50% OLM is for people that drive their vehicles, probably around 3000-4000 miles, not the 7500 miles that they often trigger on.

I didn't drive my Yukon for 2 weeks and the oil life fell 4%. So it will drop 2% a week if you don't put many miles on it.

No way they are replacing all engines when there is only a 3-5% failure rate. Just can't see that happening. That's what the 10yr/150K warranty is for. Guess we will have wait and see though.

Yes, will need to see but 3-5% failure rate is astronomical by automotive standards and the same as 30000 - 50000 defective parts per million (DPPM). Sadly, all of these manufacturing issues are on a spectrum and thus a high failure rate issue also amounts to lower intrinsic life expectancy overall.... now going to 0W-40 on the survivors will slow down the failure rate for sure, yes the warranty is very helpful and will help GM here buy themselves more time.. I'm afraid they could end up replacing the bulk as the survivors may or may not make it there, but the warranty is definitely a smart move as I don't see how it could hurt them.

I have a 2024 that was built in July 2023. I scanned it myself for P0016 and it was clear. I already changed to 0W-40. What I don’t see is any recalls for my VIN. This makes no sense because my build was definitely before the June 1st 2024 cutoff. I want to at least get a call so I can grab my new oil cap and extend from 5/60,000 to 10/150,000 on my PWT Warranty.

I have already written about the stories when people install a 2-3-4 engine, they come with broken temperature clearances from the box, their pistons jam in the cylinders from the box, I have already posted a video on this topic. So most likely, GM does not have any cold running-in. Therefore, our services, when receiving a new engine from the USA, open it and bore the cylinders to normal temperature clearances.
And they change the connecting rod bearings from the 4th generation.
Think about one more thing. Does GM have almost 1 million new engines? Most likely not, I am more than sure that they will simply remove broken engines from cars, repair them, and install reconditioned engines in others. In Russia, we already have automatic transmissions that seem new, but feel like they have been reconditioned.
Most likely the same thing will happen with engines, no one will send old engines for recycling, lol.

GM OLM works pretty simple and primitive. It's the number of cold starts, plus the engine run time, like 350 hours (I've never gotten that far because I change mine by mileage), 7500 miles, and 1 year. So every 35 hours of engine run removes 10%, every 750 miles removes 10%, and every day on the calendar removes 0.27%, every month about 8.33%.
In our region, where GPS is jammed, time starts jumping chaotically, and once in my car the time jumped forward by 1 month, I reset it correctly, then after 5 minutes it jumped forward by 1 month again, I reset it again, and for the third time the time jumped forward by 1 month, as a result the oil life in 15 minutes decreased by 25%)
