I really don’t know what it lacks, I move away from traffic lights equally or better than anyone else, I keep up with people in traffic equal to or better than anyone else, and I go 85 on the interstates equal to or better than anyone else. You’re driving a small bus not a super charged jaguar SUV. (Incidentally which I also own…A 21 not shown below..)
My Jag would run circles around this thing, but for versatility and every day use I don’t feel my Yukon is lacking anything. It warms up quickly cools down the cabin quickly when I need it goes anywhere and does anything…. half a mile or 1000 miles. No fuss no muss. I personally think it is geared very well…..

It's most likely that I'm in the minority since this is the slowest vehicle I have driven in a long time that isn't a typical compact car. I'd say most of my complaints are in the 0-45mph range. I'm fine cruising on the highway. I get it's not a supercharged SUV, but I'd expect it to at least match a 3/4 ton heavy duty truck.

With you on everything else. Glad you brought up the AC as I'm really impressed with the climate control system in there. Now that it's winter I almost traded the Ram just based on that. My Ram won't initiate full heating with remote start unless it's below 40 degrees; and it drives me insane because guess how cold it has been here lately... 41 degrees! o_O

On a side note since you brought up your supercharged Jaguar... just got my first supercharged vehicle this year (TRX), I love the supercharged engine. A lot more enjoyable than Turbo's! I'm sure you have a blast driving yours.

Similar observations here in terms of the slower acceleration from a stop . Previous suv was a 2016 Lexus GX 460 that felt slow , and the Yukon feels even slower from a standstill , however I knew that going in and still love it .

At 40 mph though , acceleration is a breeze and it feels strong on the interstate .For me, It doesn’t seem to run out of steam at 80+ mph like some others have said . Acceleration and passing at 75+ feels great .

Unbelievable mpg which is somewhat negated by the high price of diesel; although not having to even think about lifter problems makes it work it 10x over for me . Over 700 miles on one tank. Really love this car

Also wanted to add that I drove my friend’s 2021 6.2 Yukon Denali and the acceleration was almost effortless , however I didn’t want to deal with potential lifter issues . Unfortunately his lifters went out 2 months later , leaving his family stranded in the boondocks on a road trip :(

This right here is what does it for me. If it wasn't for the Dmax, I'd have a Lexus, X7 or Grand Waggy.

Altight folks... I have to make a slight redaction to my prior comments. They pertain to the 3.0 Duramax through 2022.

I recently caught wind that the 2023's got the updated 3.0 Duramax with increased horsepower and torque; the LZ0 version.

The difference was enough that I thought it could work for me, so I went to test drive a 2023 3.0 Duramax today back to back with a 6.2l gasser. IMO the new one has the right amount of power. The difference with the 6.2L was markedly less noticeable now. Sure, I could always want more, and I'm still considering the 6.2L, but to me it now makes it something I'd be happy with. Now I'm tilting 90% towards the new Duramax.

I should have clarified that I meant the truck. I'd been using my wife's 21 Yukon Duramax as a reference. I'm looking at replacing my TRX with a Sierra 1500 and was just about convinced I needed the 6.2L after routinely driving her Duramax and test driving a 2022 Sierra 1500 Duramax. Upon learning of the more powerful updated 3.0 Duramax in the 1500 I went back to the dealer in search of one that had it.

So today I drove the 2023 Sierra 1500 with the new Duramax ,and it was noticeably better than the one in my wife's Yukon. If the Yukon is still using the original Duramax then my original comment still stands that I would go with the 6.2L without hesitation unless mpg were my primary concern. If it's the new Duramax, then it's hard to pass up even with the 6.2L option.

Wow that’s some really great insight ! I love the LM2 in my Yukon but it’s really interesting to see actual feedback from someone that has driven the new Duramax as well . Makes you wonder why changes were made to a relatively new engine . Besides the obvious horsepower increase , wonder if they changed the wet belt design or if increased internal testing revealed some long term issues with the engine.


Unfortunately I’ll probably have insufficient funds to upgrade to the new diesel when the time comes lol

Thanks! Yeah, after reading about the update I had to see it for myself and report back for anyone shopping around. You'll know now for when the time comes to trade yours! Only reason I'm switching my pickup around so much is that I've bought right and breaking even on the trades. However, the market is softening so this next one I get I'll be sticking with for a long time.

If I remember correctly they reinforced the pistons, addressed the part that was causing the long crank issues, and did some updates to the belt to where the maintenance is now at 200k instead of 150k miles. Probably some other things in there I can't remember.

Good info. My wife has a 2020 GX and I wouldn’t want my Denali to be slower. Considering switching my order to a 6.2, especially since diesel here in central NC is $1.75ish more per gallon vs premium.
