I dont know much about the scope or how it works but if it's 10 years old, can it possibly be good? If it was a normal hand tool Id say of course. But in this instance, it's tech. How many pieces of tech is still great in 10 years time with all the changes that happens in between.

Especially when the electrical architecture of the truck platform has had a complete change at least once...

Here's some follow up to the picoscope video. This guy knows his business and has shared some good information on warranties. Lot's of good dialogue in the comments.

thanks for sharing, that was a good follow-up to his original video

Some interesting motor oil data in this video. His delivery isn't the best, but there are some interesting points he makes and has some good visuals.

Here’s the latest on the 10 Year / 150,000 mile warranty. GM posted it but it looks like it will only cover failure due to the crankshaft and connecting rod bearings… overage is excluded for any valve train issues…

There is something really fishy here....but the main issue is that the bearings can fail.

I spoke to the dealer here in Qatar and he said they had cases of 21-23 Yukons destroying their engines, with lifters or sometimes with bearings.

Anyways, we know how bad these engines are with the recall debacle....
Those who have had problems, best of luck with a new truck...the way every mfg produces products now makes it essential for an extended warranty...

I forgot the poor QC. Shame on them . And shame on ALL MANUFACTURERS who are trying to cut corners today. Your truck isnt the same as that in 00s....
The fact that it took them 3 TRIES to get to the issue is absurd...sure if you are struggling you can stop selling them and sell other engines instead....

Ms Mary ought to be fired.
Lets wait and see 5-7 years from now....

That's some what reasonable if your gonna keep your vehicle that long. I do keep vehicles a long time and have have three of them over 100k. Not sure I was planning on having my 1500 ZR2 that much longer, so the next question is how will the market respond to sell or trade valuations?

Also, will lifter failures be exacerbated due to heavier viscosity oil? There were theories that it coukd be caused due to tight tolerances and dirty oil. Higher viscosity might also affect it.

You mentioned three of them over 100k. Are you referring to a different set of SUVs/Cars/Trucks or the ones in your profile?

Those were examples of previous GM trucks. Two of them were 6.6L Duramax diesels.
