Decided to trade my 2020 Denali. It had replaced my 2015 Denali. They were both Black with the 6.2. So I decided I had to change it up -no Denali this time.

i bought a 2025 white AT4 with the 6.2. Wow I can’t believe how nice a truck this is, especially the interior.

just got it Wednesday, so just getting to know it. The only bad thing is that there is no owners manual - you have to scan a QR code and look at it on line😳

They are really nice trucks.

 

The interior is what sold me on my 2023 Silverado HC. The dash layout is almost identical between Silverado's and Sierra's, and there are some aspects of each I like over the other. Same with the exterior.

 

I didn't like, at all, the factory wheels that came on the '23 HC's so those got swapped out with some GM wheels that were a factory option. That black truck in your 3rd picture has them. Also not a fan of the factory "HDMI" exhaust outlets so those are getting swapped out with a set of really nice polished SS "quad" (two pipe outlets for each side) tips that bolt in just like the factory outlets.

Nice truck! There is alot to learn about the "Infotainment system". Most helpful to me was youtube. Watching someone use the system and teach me while demonstrating it was the easiest way for me to learn it.

Go to gmc or chev website and download the full pdf of the owners manual.

 

There is also an 'essentials' version (that some received with the truck) but it is a shortened version. 

 

Might as well get the warranty manual too

Yup the essentials and radio pieces came, so you get a little, but I always loved taking that owners manual to the library- usually good for almost 2 days of reading😳

I have looked at the online owners manual and downloaded pages to do a few things, but I’m just that “old dog” that doesn’t want to learn new tricks😂

Your decision.

 

I find the pdf much easier to hunt thru than a paper copy.

Eg

When index lists a page number -- clicking on the number jumps you to that page. 

When a description in on section says to refer to another section -- clicking on that will ump you to the other location.

Funny, that black truck is the 2020 Denali that I traded in -I think

that may have been the first year that those rims were offered? They really held up great!

one thing that I didn’t realize until after l bought this AT4 is that it has the same dash and the center console as the Denali-it blends from the console to the dash differently.

    • Holy s**t - not much of a parts thrower you say? You BLASTED that thing with the parts cannon!  You'd have been probably $1,000 ahead if you had just brought it to a competent shop rather than shotgunning a bunch of parts it clearly didn't need.   Just FYI - oil additives are really, REALLY good at ONE thing ... and that's emptying your wallet. They're ALL useless gimmicks.   If that has the L94 or L99, then #7 is an AFM cylinder. I'd suspect a failed lifter in that case.   If you leaned on wiring, sensors, and/or connectors while changing the oil, you'll have to check all that to be sure pins didn't get pulled out, connectors broken, etc.. Old wire loom that was barely adequate when new is certainly brittle by year 19 - make sure wires aren't chaffed and shorting out somewhere where you might have leaned. or supported yourself on it.   If your a mechanic, why didn't you just find out what you were missing and troubleshoot from there??  TIMED spark, fuel PSI / injector pulse, air, compression.  Can't make ANY money going the parts cannon route.
    • LOL! Are you joking?? That wax SUCKS! 100% gimmick made to "look" good.    After just TWO winters I had severe surface rusting in patches over 90% of the frame. Only reason it looks great in the pics is because I SATURATED the frame every single fall with used motor oil for 14 of the 16 years I owned it. Otherwise it would've been sent to the crusher 8 years earlier with the speed it was rusting prior!    I sold that POS 3 years ago. Was a gigantic headache the second it rolled off the showroom floor. Brakes pulsated on the TEST DRIVE. Door trim fell off the 1st week! Interior squeaked and rattled, and the drivetrain clunked after 2k miles. 4x4 switch failed shortly after. Front end - ball joints, struts, hub bearings - all failed between 38k-50k. Engine started burning oil at 50k. Rear and and transmission failed before 100k. Nothing but problems, and frustration with the piss-poor engineering designed to make you give up. Well, it worked! Nothing on that truck was easy to remove ... except the wheels. They haven't figured out how to screw that up yet. Give 'em time ...   I won't make that mistake again. EVER.   Such fond memories ... https://postimg.cc/K1qf23tS  https://postimg.cc/gallery/X02z64J  https://postimg.cc/gallery/mHSRXZv  https://postimg.cc/gallery/D4mMRfL
    • Different monitors do their test only under conditions specific to that monitor.  you MIGHT find the drive cycle conditions for the monitor that isn't ready on this site: https://lemon-manuals.la/   If it's not there, then it should be on alldata.com for your truck, but it requires a paid subscription.   And you need to know which specific monitor isn't ready.
    • from another thread   Update...although the truck sometimes seems to idle weird and the transmission shift a little weird, I've driven about 7,000  miles and no issues.   However, the way GM has handled my rental reimbursement, the situation when my truck quit, and the recall in general has led me to this point...I have driven a GM vehicle for the past 46 years and unless I buy a C3 Corvette, this is the last GM vehicle I will ever own.
