2023 GMC Yukon AT4 6.2L dead at 10K miles

[tj40371]

I was at delaer yesterday, asked my salesman what their fail rate they have seen on the 6.2.

He said the dealer as seen two of them in last 3 years, out of about 300 trucks. One was a Sierra, one was a Yukon. Both were top end/lifters.
His opinion from what they have seen and in talking to field rep and other dealers, is it is about a 1% problem. Which he said is "within the normal production expectations of GM"

My dealer service department said the same (and they are a very high volume dealer). The forums seem very scary about these 6.2L engines but they sell how many of these a year vs. how many reports we see on this forum?

I'm up to 14k miles on our 2023 and expect to run it up to about 75-100k before potentially looking at a replacement.

My replaced engine should be finished today. Will report back. GM not offering a buy back.

That's great - less than 16 days from tow to new engine. Bummer about the no buyback, but doubt you'll have another failure for as long as you own it.

What, if anything, IS GM offering? Does this replacement engine come with any warranty?

Of course it come with the remainder of the 5 year, 60k mile warranty.

I wonder if this a new engine, a long block, or a rebuild? Sure a shame to do a heart transplant on a brand new premium machine.

Nothing yet.

Here is another question - is an exhaust smell normal with a new replacement engine? When it idles it smells like an old car

Unsure. Here is what work order said
