How much trust do you have in the 3.0?

[dbphillips]

I think GM did a decent job on this engine but poor manufacturing quality is ruining mine -it has oil consumption. GM covered their behind by issuing a TSB saying that 1QT per 1000 miles is normal oil consumption and dealers are showing you this TSB when you come and ask to check the oil burn. I really feel anxious now when I drive long-trips and carry 2-3QTs of oil in the car. This is so 1970ies. When I drive 70+ MPH it eats 3/4 of a Quart per 1000 miles. Mine is 2023 so the failed cam cover TSB no longer applies to mine. NHTSA told me - not a safety issue thus NHTSA is not interested in this matter.

I try not to laugh at each new service advisor that gets in on our oil consumption test as we cross the country and just tell them that just because a lawyer writes something down, doesn't make it true. Besides, industry expectation is cars don't consume oil. We've all seen most cars don't. I never signed a piece of paper agreeing to that when I bought the vehicle, did you?

Have them run the test and keep the pressure on. Either it will become a class action, like Volvo did, or it won't and you have a case that your engine is defective because it's so rare.

I have a 2024 Duramax Denali XL Ultimate on order after my 2023 with the 6.2 stranded us twice. I was hoping the LZ0 would make it into the 2024s, build the build sheet definitely indicates LM2. I'll report back when it arrives.

Well, I sold my beloved 2013 Tahoe, which I had for 10 years and 82k perfect miles--it never even so much as threw a Check Engine light or any other trouble light in that entire duration.

So since I want more interior space with a longer cargo area, I am likely to buy a brand new Yukon XL SLT with Premium/Luxury Packages and the 3.0 as I have read too much, and heard from clients/friends about issues with the new gas engines. I won't ever tow anything, but we like to go way out, from North Carolina to all across this wonderful country, and frequently end up in the absolute middle of nowhere. I never once had a concern that my Tahoe would leave us stranded, but understand that with all the new technologies come new, more aggravating potential problems.

If you have or have had the 3.0, would you or did you drive it four or five thousand miles or more across the U.S. and back without hesitation? Are there any other road trippers on here that do this?

In a heartbeat! We've put 30K+ miles on ours since last July.

We've done one 5k mile trip to the PNW, another 4K trip to Canada and numerous other 1-2k miles trips with no issues and excellent fuel mileage.

Dang, I would have bought your 2013 if it was rust free!

It lived here in North Carolina since new in 2013, was garage-kept, and never had any body work or other issues, ever...just normal surface rust on some chassis components. The interior was like new since we don't have kids or pets. I listed it on eBay and Cars.com for $28k because I couldn't list it here as a new member without enough posts. Sold for $25k and was okay with that since it went to someone who was going to continue taking great care of it!

 

[UsualSuspect]

Wife's Yukon is a 23, 10K and no issues. We have a 2020 Silverado at work with a 3.0, 90k on it, no issues. My son has a 2022 Silverado, 25k, no issues. I would not hesitate buying one.

You got a good price. My 2010 w/85K miles is only $12K trade-in......

2021 Yukon Denali. 50K trouble free miles. Will be buying another.

Have you had an oil change, or are you on the factory fill? Oil usage on the LM2 during break-in is normal, such that GM adds an extra quart of oil in the factory fill. Assuming most people will go to the end of the OLM for their first oil change, that extra quart is added so it doesn't get too low with the oil usage during break-in.

I did an "early" first oil change on mine (1300 miles) and noticed the level down a bit on the dipstick at the time of the change. I then ran my second oil change out ~4500 miles on the oil and did not notice any oil usage. Recently we towed with it and I noticed the level down one section of "diamonds" on the dipstick, but I think that's pretty acceptable, especially on a turbo engine that is constantly at elevated boost levels.

I think I got a fair price for sure, and the buyer really and truly got one of the most pristine 2013 Tahoes that was available, as all of our stuff is absolutely pampered.

Now I am trying to find just the right Yukon XL SLT, of course with the 3.0 since overall, it seems like the general consensus here is that they are relialbe enough. There really is not a bigger, better, new option as domestic full-size SUVs are in a league of their own.

Expeditions and Navigators aren't even up for consideration, and I don't like the way the Suburbans look, nor do I want to pay for a bunch of nonsense I would never need on an Escalade.

2021 Sierra Denali CC w/ 25K on it. Second day of ownership had a light, and it needed a coolant hose routed differently as it did not flow correctly?? Took 1 hour. Not one issue, since then. Been bulletproof, lots of towing also. Taking it on road trip up north end of the month 2600 miles round trip. Looking forward to it and what kind of mileage i can muster. Anything I would buy today would have to have a 3.0 in it.

Oil consumption isn't a characteristic of a turbo engine

Oil consumption on a new engine is a characteristic of a faulty break in (not saying that you did anything incorrect, but the breaking in of the ring's didn't occur). This isn't uncommon; it happens. GM had horrible issues with this in the Corvette's when they went to shipping them with synthetic oil.

We just wrapped a 3500 mile trip towing a 5k lb boat, wife's 3.0 didn't use any oil.

Well, based on the helpful feedback received here on my post, I did decide on getting a Yukon XL with the Duramax.

For the last several weeks, I have searched day and night, checked the GMC website daily, and found a couple of Premium/Luxury-package equipped SLTs I liked, but none were quite perfect enough in regard to options and location--I didn't necessarily want to deal with the logistics of buying all the way across the country, since I would want to see/drive in person prior to making the purchase.

Then this past weekend I looked at and sat in a Denali, knowing right away that I had to have one of those instead. I looked for a few days for a Duramax-equipped Denali, and quickly realized that the combination of options I am seeking is even more of a unicorn in that trim level.

So I just placed an order yesterday for a 2024 Yukon XL Denali with Duramax and just about every option except the Rear Entertainment and Max Trailering packages...I don't have kids to entertain, and won't ever buy a boat or camper.

Waiting to hear back about when my order will actually start being processed, and roughly what to expect...2-3 months, 6-8 months, who knows at this point with everything going on?!?

24,000 miles & 2yrs, great performance and high fuel efficiency. The engine made me buy it and I have not been disappointed. No breakdowns. No problems. Just oil and fuel filter changes. Great dealer service. I studied test drove all the options - foreign and domestic, gas and diesel - and it was no contest. I love driving this thing. "Solid Bigness" all the way.

Great choice, good luck with your purchase. When we ordered our 2022 Tahoe RST in Sept of 2021 we had to wait until Jan of 2022. She now has over 40k problem free miles with trips from San Antonio Tx to CA under her belt at 27.4 MPG and multiple other trips to Dallas and Austin. Solid power delivery at highway speeds. I don’t understand why anyone still buys the 5.3 or the 6.2

Here is a LM2 teardown:

Here is a LM2 teardown:

Take a look at the oil pump belt at 150k looks great. No wonder they bumped it to 200k. Look at the tops of the pistons. This engine jumped time and ran long enough to damage the pistons like that. Built to run. Pretty impressive.
