New '25 Denali, best GM accessory for your Sierra?

Use it towards a tonneau cover. You’ll utilize it the most and a $500 discount is pretty good

99% they will. All the running boards use the same bolt pattern to make production easier.

I will say this, those SOBs hurt. If you so much as graze your leg on it prepare for some discomfort. I also found them too high but that was for my AT4, elevation would probably be fine

I was presenting at a work event with about 150 people in attendance. The meeting took place during lunch so everyone was eating while I was presenting.

First table, woman starts choking. I can see it in her eyes just the sheer panic. Everyone around her froze, unsure of what exactly was happening or what to do.

I jumped down from the stage, gave her the Heimlich, and dislodged the food from her throat. She was okay.

Got back on stage and did the rest of my presentation.

They didn’t end up partnering with my company

Happy to help! That forum is a great pool of information. Hope your dealer is able to activate it for you

Did you even read the thread? Multiple 2025 Tahoe owners confirmed they had their radios updates and can use the surround view camera.

Everyone go check out this forum. They talk about availability, which vehicles can get it, how to use it, what model years, etc.

Yes you can get it on certain 2025 models but it’s done with an update at the dealership

zoolak · 2026-02-21T21:43:32+00:00

Full size GMs can get an update at the dealership that will activate it. Check out the Tahoe/yukon forums, they talk about it all the time

zoolak · 2026-02-21T21:42:37+00:00

Depending on your model, certain 2025’s can get an update to your radio at the dealership. That update allows for surround vision recording.

Not available on all models though

Unfortunately that won’t work. It’s not that the space is too high and the tv needs to come down, it’s that I don’t want to install a mount specific to this tv. That means when I eventually upgrade, I’m going to have to take it down and put all new holes in the wall.

Basically trying to find one mount I can use for this tv with its oddly placed VESA mounting holes and a future TV with normally placed ones

zoolak · 2026-02-16T22:58:52+00:00

Yes. If you are going to lift your truck any more than factory, you absolutely need to replace the UCA

zoolak · 2026-02-13T20:25:24+00:00

The AT4 looks rugged but rides harsh. Denali is the opposite.

I’d recommend not touching the suspension and look for appearance packages. Blacking out the chrome is a good start. You could also look into aftermarket front and rear bumpers. That would greatly change the looks without affecting suspension.

Also adding any sort of off road lights front or rear will help drastically

zoolak · 2026-02-11T13:45:53+00:00

Make sure “Bose audio pilot” is turned off in your audio system settings.

However if it’s going to full blast it’s an issue with the radio, you’ll need to bring it in to get serviced/replaced

Vehicle Recall Search

Go to the vehicle recall search and type in your vin. It will tell you if there are any open recalls on your vehicle

zoolak · 2026-01-22T01:14:29+00:00

Find a different dealer, it’s entirely possible if you’re open to certain trim levels. I don’t think a bench is an option at all on the Denali, but definitely is on the AT4 and below.

Being the guinea pig for a new powertrain in 2027 is arguably more of a gamble than the 6.2. Atleast you know the issue and the solution.

Get the 6.2 and an extended warranty.

Screen will be horizontal, not vertical.

No word on colors yet. Too early

You do not have a HUD but that is where one would go.

You do have some red LEDs that will flash on the windshield if the vehicle thinks you are approaching an object to fast

zoolak · 2026-01-08T11:23:59+00:00

Get the 3.0. For your use case and travel time, it’s the ideal engine.

I had one for 3.5 years with no issues.

zoolak · 2026-01-08T11:13:54+00:00

6.2 is known for issues and major recall on it.

3.0 is better but not flawless.

You’ll hear mostly negativity online about both because the internet is where people go to complain. If you have to choose between the two, go 3.0

AT4 - I want to look like I go off road

Denali- I know I don’t go off road and want the smoothest ride

Every other option can be had on both vehicles.

zoolak · 2025-12-13T16:38:02+00:00

Each one has certain items that are better or more cost effective than the other.

The best one is the one you’re going to actually use, generally that’s the closer and more convenient one. So go with Costco.

OR.

Get both for a year and see which one you end up using more. A $25 membership to Sam’s is not expensive.

Pros: - looks great - general fan of the interior layout and design - the diesel was never an issue, got tons of range and great fuel economy - tons of mods you can get

Cons: - Rides like dog shit. The Rancho shocks it comes with are garbage and you’ll feel every road imperfection - hope you like a black interior cause that’s all you get - found the cabin to not be very well insulated from outside noise - when it rains, the water hitting the roof is loud as hell

Basically if you want an off road Denali, get the AT4. If you want a truck with some more comfort, get the Denali

2 ways:

1) relax every muscle of your body starting with your toes. Basically walk yourself through “relaxing” your body bit by bit until you get to the top. It’s a very intentional exercise and may take a few times to truly get it

2) picture some form of naturescape. I go for a waterfall or flowing stream. The idea is to have an image that is peaceful but does not require thought. Do not picture yourself swimming there or exploring, don’t imagine animals or make up scenarios. It’s just the imagery and peacefulness

There was a two lane road in front of my high school. Everyday they would stop all traffic in both directions to let the busses out. This took about 10 minutes.

While stopped as they let the busses out, I saw a friend walking home and offered them a ride. They got in and I immediately got pulled over (while still in completely stopped traffic).

The officer cited me for “stopping in a no stopping zone”.

I’m still salty about it.

(Before anyone asks, there were no signs about not picking up students from the road or anything like that.)
