So, it sounds like the dealer network gets priority over the customers because regardless of whether the unsold trucks on the lots are new or used they get new motors, while customers with trucks only get an oil switch to 0w40, unless the motor is compromised at time of inspection. 

 

Something is not right here. Please tell me I'm reading this wrong because this sounds completely unfair.

 

 

Its big enough to have a phased launch which they've done before in the past with other recalls.  

 

I can say I ran a couple customer VINs, they fell under the N252494000 recall which is "incomplete, remedy not available".  N252494000 is the inspect for P0016, if its ok change the oil to 0w40.  

 

It is possible that may change as this is all fresh still.  I suppose it is also possible that those that get the oil switch could end up with some sort of extended coverage that would provide an extended warranty on the engine if it fails down the road , but again, the information is coming out almost on a daily basis.

That wording right there sounds to me that we indeed get new engines, too, because, unlike in the previous bulletin, nowhere in this bulletin does it say anything about an inspection, it only talks about engine replacements of motors built within certain dates. Does this 002 supersede the previous bulletin? 

 

 

There are 3 recall numbers.  No superseding that I can see.  N252494000, N252494001 and now N252494002.    

 

Trucks with N252494000 that were placed under stop delivery will now be serviced under N252494002.  But they have not transitioned customer vehicles yet I don't think.

Sorry if this is a stupid ?  But all the Pensoil 0w40 is not listed as having a dexos approved on the label.  Mobil ! does show it on the supercar oil.

You understand what I am saying, right? If all the trucks, new or used (and maybe even older than my 22 refresh) get new engines and I don't, they instantly become more valuable than mine because no one will want mine. So, if they don't replace my engine, I have grounds for a lawsuit for reduction in value because they don't replace mine. That, I would think, would end up costing GM more in the long run. Maybe they hope I get in an unrelated accident that totals my truck, or die, which would then save them money. 

 

But, hopefully, you're right, and things are still developing and could change. I guess that's the silver lining in why they're not sending us letters until June 9.

I wouldn’t buy anything used with cylinder deactivation. So that takes GM and Ram off the list. I wouldn’t buy any Hyundai with a 4cylinder engine after their problems. I’ve had great luck with Hyundai and GM. There’s alternatives out there so why take the chance? There’s other published problems with different brands. I stay away from those. The cure is warranties. Anyone who doesn’t search the internet or get a car fax report is very foolish. I definitely wouldn’t purchase a vehicle that has a replacement engine. That would definitely raise a red flag for me.

Correct.  Its not.  Dexos R is the spec for the engines getting 0w40 and its a very short list of oils that meet Dexos R at least in terms of being licensed.  

 

Anything that was Dexos 2 approved however would work as the old Dexos 2 spec has been split into Dexos D for small diesels and Dexos R for gas engines.  

 

So if there is any stock of Mobil 1 ESP Formula 0w40 and Mobil 1 ESP x3 0w40 left, those can be used.  Otherwise they want Dexos R spec oils found on this list - dexos®R | GM

 

Dexos R is low sulfated ash for emissions protection (catalyst protection) and was chosen initially for Corvette and Camaro to have as a daily oil and track oil instead of switching like they did on 2014-2018 LT1 and LT4 engines.

Yeah lots of this can change by June 9th if that is when they will start sending letters.

It's probably not even worth going to the dealer yet, right newdude?

I might just dump my 23 HC 6.2 and get a new 2500HD 6.6 Gasser before then  and not have to worry about lifters and rod bearings any more.

I wouldn't step foot in just yet as all this info is just as fresh to them as it is consumers.  Plus they can't do anything yet as two of the three recalls so far have the "incomplete/no remedy" status.  Not sure if any trucks have 002 recall assigned to them as sometimes it takes 24-48hrs for GM to update their statuses.  

 

You can trade at your leisure but be aware you might take a bit of a bath on trade in.

so update from tonawanda....

tonawanda makes (machines) the cranks for the 5.3 and 6.6 at the plant.

they do not make any of the rods or pistons

the rods and pistons come pre-assembled

still trying get info on source of LT cranks and rods, they're going to try and find out.

they didn't actually know where the L87 parts were coming from but they did not speak well of the mexican made 6.6HD cranks..... "they're trash"

Sediments and crank dimensions/ finish. After all these model years, I wonder why the Camaro and Vette 6.2`s are fine?

I THINK the LT1/2 are built on a different line. LT4/5 were/are hand built at the PBC so they wouldn't be affected by this.

GM now revised the recall and are replacing all 2021-2024 L87's. Wow this is going to be huge and take years like the Toyota frame replacements. Going to cost billions.

Please read a bit more.  There are 3 versions of this recall.  Not every truck will be getting an engine at the moment.  Some trucks are tagged with the engine oil switch recall.

On another forum, the below was posted. If the warranty side ends up being true, I can totally live with that.

I've not seen it yet in any of the most updated versions of the recalls but if correct, it is only on the trucks that pass and switch oil weight.  If it gets a replacement engine, no extended coverage as the new engine is outside the defect window.
