New to Yukon world

[typk33]

Hey everyone!
We just purchased a 24 Yukon Denali with 28k miles to add to our 4runner and Tundra. Super happy however the engine failure is always creeping in my mind. Please give me some reassurance that we didn't just burn 70K. Once the powertrain warranty dies im throwing on the longest extended warranty I can on it just to be safe.

Any notes and comments very welcome!

What do you like about it? Did you switch it over to 0W40 engine oil?

Just bought it today. It's my wife's car and her goal is to keep it for atleast 200k miles, 10+ years. We love the way it rides and the interior. Scared of the engine but our other option was the seqoia which has the engine issues as well. Looks like they completed the recall on Jan 5th, guessing it passed since we bought it today and it was traded in Friday for an XL. I forgot to ask if it passed but will in the am. Im guessing thats when they switched the oil to OW40.

Congratulations on your purchase, we're all going to die someday, so is it worth thinking about it all the time and not enjoying life because of it? I think not, so don't worry, just enjoy the wonderful car.

Have or confirm the PICO Test, run with the 0W-40 oil, and enjoy it. You have a warranty for the motor. For me the biggest thing is that the actual engine failure rate seems to be below 10%. That does not mean that I do not worry about the motor, just that my concern is a little less. I do not do much highway driving so what I see as the worst case situation, loss of the engine at highway speed, is of limited concern for me. We have a 2022 Denali and right now are at 26k miles. Running just fine, knock on wood.

Lots of knowledgeable folks here who freely share their knowledge, experiences, and perspectives. Knowledge is power.

I hope that you will become a participating member in the Forum's discussions.

The more that she drives it, the more she will love it.

Welcome to the forum! Good looking rig - very similar to mine. Aside from the engine checks I'd suggest doing a basic inspection for a used vehicle (fluids, etc). 28K miles isn't much but verifying these are in good condition should relieve some stress.

 

[typk33]

Appreciate all the welcoming messages! Looking forward to being active here. To clarify, car was sold from our dealer originally, serviced here, and traded in for an XL. Inspection done and everything looked good. Currently have a quote for 120k miles, 8 years for 2200. Might just grab it now.
My biggest worry is with my wife driving 50 miles a day on the hwy that it shuts down with her and our 3 yr old in it. Otherwise I dont mind since I'll be covered warranty wise.

At your first oil change, you might consider taking an oil sample and sending it off to Blackstone Labs or similar for analysis. I do this every year or so on my vehicles for the engines and transmissions.

I think you will really enjoy your vehicle. I've got a 2021 with the 6.3 and received the recall notice. I bought the truck with 25k miles and immediately switched to Amsoil signature series 30 weight oil. I do oil changes every 15k miles (the oil is rated for 25k miles) per my mechanic's advice. I've got 130k miles that includes quite a bit of highway towing with zero engine issues.

Warranty is not going to prevent that from happening, it just helps with the consequences. So yeah, just keep on trucking and don't worry about it. Maintain it with preferably shorter than advertised intervals to keep fresh oil in it and enjoy.

Catch can would also be a good addition. Unless the warranty folks would go cuckoo over it, I guess. They shouldn't, but still...

Welcome to the forum! Curious, is that a third party warranty? or is this the GM warranty?

Congrats on the new ride! Let the mods begin!

BTW, I'm 99% sure that the dealership could not resell that truck without doing the PICO test on it. So, you should be confident that you either have a new engine in it (not at all likely), or they did the test on it and it passed (and you have heavier-weight oil in it now). Without calling and asking the dealership about it, you can pop the hood and check that the oil filler cap says 0w-40 on it (vs 0w-20) -- and then you'll know that the engine was tested and the oil changed.

THAT BEING SAID, there have been some failures after the test/oil change. So, none of us with the 6.2 are "in the clear" now. But, I've had a little more peace of mind since the test/oil change on my truck.

Enjoy!

That would depend on the production date of his engine. I believe the cut-off for the recall was for anything built after May 31st 2024. But since OP mentioned it passing the test, assumption is that the engine was made prior to the cut off.

Can't appease you...6.2 fails are real. Mine failed 5000 (At 44.8k) miles after the recall/pico test/move to 0W-40. Pretty sure there are numerous reported fails after the recall update.

That said, the known failure mode (rod or crank bearing fails) is covered to 10 years and 150k miles under special coverage provided for the recalled vehicles. So, assuming yours had the recall remedy, you should be able to look up your warranty using your VIN, and should see the special coverage applied. See here. If you don't see it applied, and don't see the recall completed or open, then your engine probably was outside the recall date, which is a good sign, but unclear just yet if you are "out of the woods."

My dealer says most service contracts (commonly referred to as "extended warranties") are not covering the engine fails, and those are going back to GM if they are due to the bottom end issues. You do not want to wait to buy one if you want it, they are way less expensive when still under the factory 3/36 coverage. Recommend checking online at Granger Warranty, Knapp Service Contracts, or a few others. Those have historically been the best price. (This is not me advocating to buy one, nor advertising a particular retailer of them, just passing on what I know. A search of the boards will tell you I am not an advocate of service contracts...the consumer as a whole always loses: service contract companies are in the business to make money.)

I wonder if the crank failures are related to the high pressure oil pump being factory disabled so it can play well with the AFM. I discovered in my 2020 the thing was shut off with a trigger point of 7000rpm something it will never see in real life, while police units have the cal set at 3500rpm. I am not too familiar with the 2021-up calibrations but perhaps someone can read one wioth HP tuners and share the file.

Crank faliure published reasons (By GM) are:
-Sediment left behind from casting process on connecting rods and in oil galleys of the cranksaft.
-Improper machining on rod and crank journals.

The latter has been confirmed by a couple reputable online sources (Search Dave's Auto and IdoCars channels on YouTube).
