    How to Tilt Sunroof with Shade Partially Closed

    With past SUVs I could have the sunroof shade open just a crack with the glass tilted. This allowed for a bit of air flow without much direct sunlight. This did not seem possible with my 2025 Denali. Actuating the Tilt control also opened the sunshade to the ½ way point. Facebook Link suggested...

    2025 Denali Driving Modes

    Does a more detailed description of the 2025 Yukon Denali driving modes exist? The explanations I have found are quite vague and go no further than “Improved traction” and “Enhanced performance”. My sense is that the Sport vs Normal mode invokes: -A bit stiffer suspension. -Delayed up-shifts...

    How to Crack Windows Open? '25 Denali

    What is the trick to just cracking the power windows? I understand a press and hold fully raises or lowers automatically. A momentary press seems next to impossible to achieve. If I do a quick push up, then down, and after some fussing, I get the window where I want it. This is using the drivers...

    Adhesive for Plastic Panels

    I have had little success in using adhesive backed Velcro on the plastic interior panels. I have tried some said to be for low surface energy materials like ABS and PP but they all detach eventually. Any adhesive recommendations?

    Forced Regen

    Expecting to soon have my 2025 Yukon LZ0 back from dealer service after 6+ weeks. During that time it has been driven no more than in and out of service bays in addition to some hours of simply idling. In anticipation of this long-awaited homecoming, I am planning an out of town trip to test...

    Accept Buy-Back or Not

    2026 Yukon Denali 3.0l 8,500mi My Yukon has been at the Dealer for 21 days to correct a recurring CEL and frozen touch screen issue. It’s been in 8 times prior for these and other presumed software problems. Each time so-called updates were done and several modules including the steering wheel...

    Connected Phone Not Displayed

    2025 Yukon Denali 3.0l Duramax After numerous dealer updates to solve various problems, the connected iPhone name stopped appearing at the top of the infotainment screen. OnStar could not solve this after several attempts at disconnecting, forgetting, restarting the phone and infotainment...

    Service Performed Codes

    2025 Yukon Denali 3.0l Duramax Is anyone aware of a decoder sheet for the Dealer "Service Performed" codes, warranty or otherwise? I'm guessing there are not unique to every dealer.

    Stabilitrak & 4WD

    2025 Yukon Denali 3.0l Duramax Electronic Locking Rear 2-speed Transfer Case Does Stabilitrak improve 4WD traction in conjunction with the open front differential? Will it brake the spinning wheel allowing the one with traction to grab? I have seen videos showing quite a bit of wheel spin on...

    Installing Locking Lug Nuts

    My Yukon was missing the locking lug nuts from new which I now received. Thinking of installing them, I am uncertain of exactly how. I am tempted to simply remove and replace a nut on each wheel with the truck on the ground. I also understand the proper convention is to incrementally torque all...

    Reported Life of Filters/Oil

    2025 Yukon Denali 3.0l Duramax Does the reported life remaining for the filters and engine oil actually reflect a measurement, or is it just an hour meter?

    Aux. Battery 2025 Yukon Denali Diesel

    I am planning to install Ham Radio equipment and haven’t seen any provisions for an auxiliary battery for the 3.0l Duramax, PPV or aftermarket. Has anyone installed a second battery?

    Door Pocket Liners

    Has anyone lined the Cheap-O plastic door and console pockets to keep contents from rattling? Suede-Tex would work but believe it would be difficult to apply evenly and neatly. Cutting and gluing fabric or other soft material would seem somewhat tedious to do neatly even if using patterns.

    22” to 18” Wheel Swap 2025 Yukon Denali

    Decided to downsize the wheels on my 2025 Yukon Denali from 22” to 18”. I wanted more air and rubber to cushion the road surface and disliked the appearance of the now popular low-profile wheel/tire combinations. Enough online opinions suggested that this would be possible. My original wheel...

I’ll be installing recessed D-ring tie downs into the plywood for a slide out kitchen unit and for general use. I would like to cover...

    Nomad Kitchen Install 2025 Yukon

    Has anyone installed one of the Nomad or similar kitchen units in their 2025 Yukon? I am especially interested in what you used for the rear tie down anchor points. I would prefer not having the straps span across usable cargo area preventing easy slide in/out of other gear. Apologies for...

    18" Wheels, Grille Swap

    I will likely be ordering a Yukon Denali 3.0l with the Denali Reserve, Advanced Technology, and Premium Capability packages. I am thinking about asking the Dealer to swap in 18” wheels as part of the deal. My objective is to maximize ride quality and add Curb Rash resistance. I prefer the...

    2025 Yukon 3.0l Diesel MPG Discrepancy

    Just lifted a window sticker of an In-Transit Yukon from the internet. The fueleconomy.gov mpg on the sticker indicates 24mpg highway but the fuelenonomy.gov web site lists 26mpg highway. Any thoughts on why the discrepancy?

    2025 LZ0 Identification

    I don’t see a specific engine type called out on the window stickers I have seen on dealer's web sites. Where or how can the engine type or designation be confirmed? When available, I will be wanting to confirm a new Yukon does indeed have the LZ0. Does GM or new cars in general still use a...

    Acoustic laminated glass

    The 2025 Yukon Configurator lists Acoustic laminated glass in the build summary for the Denali Ultimate but not the straight up Denali. Do all trim levels have it and am also wondering about the Tahoes. The Configurator is somewhat buggy. Mike
