I disabled the tilt mirror in reverse option. Not helpful when backing up long trailers. The bottom convex mirrors work just fine to see where your tires are .

[@remingtonp1k52]

I did the same. Nice option for no trailer, but pulling my 41’ TH 5er that not helpful

[@SliderFury1]

Yeah, when you have split mirrors like that and you set the lower mirror in the right spot, you never have to move them.

[@charlesb4267]

There is one item that may not have been mentioned, its been hidden so well by GM on the refresh model that no one had ever been able to find it .... and that is the 12 volt socket plug for the myriad of devices that people own or can buy to this day that require that socket to be powered period or charged, examples of a small tire inflator, mattress pump, stand alone GPS unit, older phones ( yes they exist ) radar devices and on and on and on.

[@KompressorV12]

You’re right, we should bring back the aux cord, cd players, and micro usb ports. USB C can support way more power than 12v.

Idk why people cry about this tbh, when I got my '24 I was a bit lost that it didnt have it so I just bought one and installed it. It wasnt hard lmao

[@justincausey5196]

My '24 SLT has one in the dash and I could've gotten one in the center console, but chose not to.

[@charlesb4267]

@@justincausey5196 You have the refreshed dash ?, I've never heard anyone mention they had a 12 volt plug in the refreshed truck period so something is oddball there. I know that the work truck and custom trim for 2024 was still the prior dash style so it definitely had the 12v socket setup in them. Do you have the console with bucket seats or the bench seat ?

[@Sahasra_doesrandomthings]

Can you please advise on the below 1. Does the cameras turn on automatically when we are in low speeds like 10mph ? This feature is in tundras. I'm not sure if we have it in denali. 2. The rear view cameras are like HD vision, front and back, and top. BUT the sides cameras near tyres and blind spots are like VGA cameras. Very bad quality. 3. When a vehicle is on blind spot, it blinks in mirrors. Do we have an option for a sound alert when turning?

[@erice9536]

To lock out the tailgate, you just need to hold the top button. Thanks for the infotainment review, learned something there. Just got my '25 last week, pretty sweet truck.

[@GabrielSedlakOfficial]

Appreciate that🙏🏼 Glad you're enjoying your new truck! 🎉 Congrats on the new ride!

[@charlieromeoh]

Test drove an identical one today, was shocked to find the blind spot mirrors are not powered and the pedals are not adjustable, both options are offered on the ram 🤷‍♂️

[@GabrielSedlakOfficial]

AGREE.... that would have been such a great add on 🙏🏼

Maybe I missed it, but where is the setting to turn on the mirror lights when reversing? P.S. Glad you were able to customize your shortcut menu!

[@Jerzeyguy]

There isn’t one. Unfortunately

[@toniogonzalez0506]

They work with the cargo lamps, as you shift to Drive they go off, when shift to reverse or park they come back on.

[@ryan_torres]

Thanks for the info! Sounds like it doesn't work like I thought it would. I was thinking you could set it to where the lights would just come on when you reverse. That would be a nice feature to have.

[@toniogonzalez0506]

@@ryan_torres well you can do what I did on my previous sierra 1500. I installed aftermarket tow mirrors , ran the harness to the fuse box and wired those to the reverse fuse, that way they will be on every time you back up or the perimeter lights are on, either you unlock with the key fob or cut the vehicle off at night. They're great spot lights to get to your truck in dark places.

[@SuperDaveTX1]

Thanks.. Helped me out with a few things.. like the changing of short cut buttons on the main display. I too wanted too wanted a camera button right on top! Now if I can just find a fog light upgrade... The ones we have suck!

[@GabrielSedlakOfficial]

Glad it was helpful! 🙏🏼 Fog lights... I want to upgrade mine as well. Morimoto and Baja Designs make great ones... but not sure they make them for the GMC, somebody does..... now you got me on the hunt too! 👊💥

[@SuperDaveTX1]

@@GabrielSedlakOfficial I contacted Headlight Revolution where I got my light upgrades for my 2018. They say nothing out yet, but soon and reach back to them in a month.

[@ColoreDiVita]

Also to mention for those who don't know they have the HUD is there are multiple screen options you can choose from by hitting the "HUD" button to rotate through them. I love having the navigation info. on it along with other info. Just wish it would get brighter for using with dark polarized sunglasses in bright daylight, but the dimming feature for night is great. I didn't think the HUD would be something I'd like, but I do love it.

[@GabrielSedlakOfficial]

I didn’t realize how much I love heads up display now it’s one of the things I have to have on a vehicle. I’d rather just look at the edge of the hood and see what I need to see and not look at the gauges and thanks for that info about the HUD adjustments. That is super important. I know a lot of people are reading the comments. Thank you so much!

[@TroyGouldYYC]

Also after adjusting the HUD, use the memory set feature for your seats so that the HUD adjustment is matched to your key fob.

[@ColoreDiVita]

@@TroyGouldYYC Good tip. I didn't know that was attached to the memory feature, which I use because they usually mess up your seat position when you get the car serviced. I'm the only driver otherwise, so the two key thing doesn't really apply to me, but if it ever does, that's good to know that the HUD position stays with it. Sometimes, my side mirrors don't come back up to the right position after backing up no matter how many times I save my settings, but hopefully the software update the dealership did has fixed the problem. I suppose if it isn't fixed, I could just turn the curb setting off because I honestly just use the cameras 99% of the time backing up.

[@johnnyfcooper]

Very good video. I have a Denali and enjoy this feature. When you have a trailer attached and actiivate a right or left turn signal, the rear facing right or left camera comes on until you finish your turn or lane change. Again good video.

[@GabrielSedlakOfficial]

Thanks for the info! I love turning cameras... need to try that feature 😎

[@Invinceration]

Great job, thank you. How do I have the dome lights turn on when I open the door?

[@boltactionshooter]

There is an overhead button right by them. Hard to find at night.

[@mrpickle219]

Another setting for when you leave your keys in the truck. When you close the door you can make the horn honk twice really quick. This tells you there inside.

[@GabrielSedlakOfficial]

That feature has been helpful quite a few times for sure! Thanks for the comment and for watching 👍

[@LeslinAdventures]

Thanks man. Very informative. It helped me a lot 😊

[@elderrob]

Thanks for the video. I hear a lot if people, or some, complain about the comfort of the seats. They say they are too firm. What are your thoughts?

[@GabrielSedlakOfficial]

They are on the firmer side, yet still very comfortable. They are the best ones yet, and I had the 2017 Denali HD, the 2020 AT4 HD, and now this one.. definitely the best one. Super comfort, I wouldn't say that, I think the Ford Limited, and especially the new 2025 Ram coming will be the most comfortable. They say it's Mercedes-level. That will force everyone to follow soon after. I have driven this all over and taken long trips and never had a fatigue problem and remarked how good the seats felt even then on road trips. Hope this helps? Thanks for watching 👍

[@remingtonp1k52]

They are on the firmer side. My 15’ Platinum Ford SD was more conformable. But if you play with the many settings to your liking, they are not bad. The firmer seat will hold up with time and miles tho IMO

[@williamnimmons8949]

For me being 6'2" the seats would be no problem and they let down in my truck to where my 5'2" wife can raise them to her comfort zone Sir !!!

[@ColoreDiVita]

The seats are very comfortable, especially if you use the massage feature! Be sure to adjust the lumbar etc. to your liking first. And save your seat settings to your key fob/driver number. The ventilated feature is also amazing and feels refreshing (especially good since they don't have air vents in the ceiling as in my SUV I had one of the rear ceiling vents aimed at my neck while driving). Heated seats are okay, I just get too hot with them after a few minutes, especially on the bottom, and I hate the heated steering wheels for all time. But, the seats are great for short drives, long drives, and road trips.

[@NobleRenovation]

I really enjoy the enthusiasm you show for your truck. Do you know if the majority of those 18 features are available on the lower trims such as the base Denali, XLT, and XSE? Are any specific only to the Denali Ultimate?

[@ZeroSixValkyrie]

[@boltactionshooter]

@@Dreamz1998 and the speakers in the dash and too on dash. I think the AT4 is a much better value thus why I got one.

[@Gubers]

The best camera feature IMO if the add-on trailer camera. It enables transparent trailer mode which uses the truck cameras and a camera mounted on the rear of your trailer that plugs right into a port next to the 7pin trailer port. It works amazingly well and basically looks like you can see clear through your trailer to see what is around the entire thing while driving or reverse. It also enables trailer assist backing which adds guide lines and a diagram of the truck and trailer orientation as you back up to help you back the trailer up right where you want it. It’s way better than any trailer camera system I’ve seen before. And it integrates right into that big beautiful display with all the other cameras. If you have the 360 camera system you have those trailering camera ports. The other port you can mount a camera inside your trailer with or you can put a camera pretty much anywhere you want.

[@GabrielSedlakOfficial]

I can't wait to try that out!! I've never added a big trailer that would block the view yet. Now just from your comment, it makes me want to pull one 😎 Thanks for the comment and for watching 👍

[@SaltwaterPitBull]

Great video! I did not know about the auto window down feature! 2 things Ill say after 13k miles on my 24 HD AT4; - The reverse tilt mirrors had me excited at first, but I found when you go back in park or drive, they dont reset to exactly where I had them programmed to. So I have to readjust them each time. I ended up just turning the feature off because it was so annoying. - The mirror "spotlights" are not nearly bright enough to help much with visibility if you're working around the truck at night. I plan on replacing them with brighter aftermarkets that will also work when the truck is in drive with the brights on. One tip I'll mention to other HD owners that piggybacks off of your highlighting that the cameras still work while in drive; The front camera is incredibly useful in heavy rains as it seems to almost completely cut through the "whiteout" affect tou can sometimes experience when driving in heavy rains. But, definitely, DO NOT use the intelligent cruse in those rains! Thanks for the great video!

[@cjdoc21]

Did @anyone mention the spot lights can be turned off one at a time with the same button? It allows you to cycle each side or have both on at the same time

[@GabrielSedlakOfficial]

Never tried that! Thanks... I'll check it out! 🙏🏼

[@ladiesman0921]

Does the 2024 Denali Ultimate 1500 have the night vision feature? I just get a dark, almost no view camera screen when going into reverse at night.

[@antonbalek2968]

Great video. Does your 2500 beep a horn when you reach suggested psi as you air tires up? My 1500 Denali does that. It's a brilliant feature, I use it a lot after driving on a beach. ... Are the Ultimate seats any softer than regular Denali?

[@GabrielSedlakOfficial]

I totally need to check that out! I purposely lower my tire pressure by around 7 to 8 pounds per tire because I don't like the 70 in the rear and the 60 up front it makes a huge difference in the driveability and the comfort. As far as softer than the Denali, I'd have to sit at them side-by-side the seats are definitely on the firmer side that seems to be the consensus across the board when comparing them to a RAM or a Ford. I'm sure GMC will address that soon because the new tungsten ram and the Ford Limited are quite luxurious the GMC seems to have designed it around function and durability, but I do like softer seats. I've had so many luxury vehicles that it kind of spoils you but everything else is so great on the truck it did not steer us away from getting it. They are definitely softer than my 2017, 2020, or 2023 GMCs but still a bit on the firm side. I hope that helps thanks so much for the comment 👍

[@elderrob]

Thanks for the thorough response!

[@GabrielSedlakOfficial]

Do you know why California doesn’t get the marker lights on the roof of the truck? Do you know if that’s an option to add?

[@GabrielSedlakOfficial]

I just found this answer: Crazy I know 😵‍💫 In the United States, any vehicle that measures in at over 80 inches wide will fall under commercial vehicle guidelines. These vehicles must come equipped with “three amber front and three red rear identification lamps spaced between 6 and 12 inches apart at the center of the front and rear of the vehicle, as high as practicable,” as per the federal government, but this does not apply to the single-rear-wheel versions of the Chevrolet Silverado HD and GMC Sierra HD in California. So, what’s the reasoning behind this? It turns out that California has a law that overrides this federal regulation and the reason why is a bit ridiculous, in our opinion. According to California Vehicle Code 27606, “no person shall own or operate a motor vehicle which is equipped with a light bar, or facsimile thereof, to resemble a motor vehicle used by a peace officer or traffic officer while on duty within that jurisdiction.” The law goes on to explain that a “light bar” can refer to “any light or device affixed to or mounted upon the roof of a vehicle and extending the width of the roof, or a substantial portion thereof, which emits amber, red, or blue, or any combination of those lights.” Simply put, California law mandates that a vehicle cannot have an amber, red, or blue light bar mounted to it that spans the width of the roof, as other motorists may confuse the vehicle for law enforcement. 😵‍💫😳 Thanks for watching, hope this helps/ 👍

[@bensb166]

Hey Gabriel, how do the accessory plugs work, are they switched w/key or always live and the 120v both inside and in the bed are they also switched. Also is there a run down setting on them so you don't run the batteries all the way down. I can't find any info on them and mine is on order waiting to get built. Thank you for all the information.

[@remingtonp1k52]

The accessories are key on power only from what Ive experimented with on mine. Typical of Auto manufacture’s. Im sure there are some software programs that can change this u just have to find them.

[@toniogonzalez0506]

All of the accessories come live as you open the door and stay on as long as the radio is On, or obviously press the Start/Stop button without starting the engine. SAME for the Hotspot. But for the 120V plugs, the engine has to be running to work, no switch, always ready to use as long as the engine is on. But, if you leave your engine idle, auto shut off will cut it off in about 15 minutes. Need to go in and step on the brake or interact with the truck somehow so the engine runs for additional 15 min.

Thanks for the video, I learned a few features I did not know I had. Unfortunately, the build quality of these trucks just isn't what it used to be. Multiple DEF , ECU, yolk, transmission issues. I've had my Denali brick itself 5 times on the main road. To top it all off the seats are horrendous for a truck at this price point. If you spend a large portion of your day in it you will be disappointed.

[@GabrielSedlakOfficial]

Thanks so much I’m glad it was helpful. I do agree. Vehicles are getting way too complicated and it does have the tendency to add to repair visits. The seats are the best they’ve had yet I had a 2017 Denali HD, I had a 2020 AT4 HD and the seats got better with each upgrade, but this one is by far better than the other two it’s still is not the level of the Ford limited… or have you seen what Ram is about to bring out with their new 2025 tungsten addition the interior is more on a Mercedes level I think it’s going to force the whole truck world up there game substantially.

[@GabrielSedlakOfficial]

Sorry for the delay in my response... just read it, did you ever figure it out? There are 2 buttons under the sunroof controls. The one on the left when the orange light is on the door lights work, but with it off they do. The right button is simply an override ON-OFF switch, make sure that it's off so the lights don't stay on after you lock the truck and walk away so your battery doesn't die... Hope that helps?

@GabrielSedlakOfficial your welcome I thought that was really cool when I saw that

[@roberttyminski4203]

Does GMC ultimate has lane centering?

[@GabrielSedlakOfficial]

yes, it does 👍

[@roberttyminski4203]

@@GabrielSedlakOfficial and ...what it does not have is CP4 pump👍

[@jbyrne9073]

Are these features on all HD sierra trims ?

[@GabrielSedlakOfficial]

Not all do. I always do a side-by-side model comparison you can do that on the GMC site. The Denali Ultimate just has everything you can imagine on one truck. It’s the highest trim level. All the models come equipped very well, but beefed up luxury options are added to the ultimate. Thanks so much for watching !

[@dalelangehennig161]

What kind of fuel mileage are you getting on the highway?

[@GabrielSedlakOfficial]

On the high end, I've hit 22 before, more like 19/20 on a good road trip, and that's with 5 of us riding and about 400 lbs in the back. Thanks for watching 👍

[@coryohanlan194]

That’s exactly what I get, my “best” says 22MPG but really its 11 city/19 highway

[@TheAlexrod]

A wife and two young drivers., no wonder what you are low on fuel.. I thought I was all alone in this world.. 😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂

[@GabrielSedlakOfficial]

LOL! I know right.... always filling up with the crew for sure! 😵‍💫😆

[@remingtonp1k52]

As the saying goes and I tell my wife, I dont always drive my Wife’s car, but when I do the gas gauge is on E 😂

[@racsobadillo2120]

Same my Denali 2024 is on E rn💀

[@jeffreymcneil8480]

Read the owners manual…it’s all in there, it’s not hidden 3:22

[@toniogonzalez0506]

Idk Y I feel so jealous of your sierra when i own my own with almost the same features 😂

[@shogun4200]

Watching this video at midnight and I wanna go drive mine rn. Haha, I think it’s his excitement for our trucks. They’re awesome and this was a fantastic reminder.

[@GabrielSedlakOfficial]

😂 I know right…. Sometimes I’ll watch videos of basically the same stuff I have and I go why is that look so much better than mine 😳Appreciate you watching! 👍🏼

[@svengrafen7605]

Love how GM has features that Volkswagen did 15 years ago lmfao get with the times 😂

[@jamesmartin3895]

You can set the feature on so that the horn chimes three times if you leave the keys in the vehicle

[@GabrielSedlakOfficial]

That one I had to figure out too.... drove me crazy at first, but appreciate the feature for sure. 😁

[@ruddogbp]

Do not do that on the steps, where he shuts the door and puts his foot on it. Mine didn’t go back up. I’ll be taking my truck into the dealership to get fixed. 😂🤦🏻‍♂️ Once in drive, it kept going up and down but never went completely in anymore. Instead use the settings button and deploy or stow it away from there.

[@GabrielSedlakOfficial]

Thanks for the heads up! Goodness... 😳🙏🏼

[@cdweddle]

I think for the price it should have a sensor that knows their is a trailer or hitch and do that tailgate lock for you automatically.

[@GabrielSedlakOfficial]

Great Idea! I know GMC has been getting TONS of feedback on how to improve it....I hope they add those benefits soon. Thanks for watching 👍

[@shawnjones3907]

What’s the bed length?

[@GabrielSedlakOfficial]

I chose the 6' 9" standard bed. There is a longer one that is 8' as well. Thanks for watching 👍

[@alexkondryuk7330]

I’m pretty sure this man knows his truck way better than Gm. I bet they are also watching this thinking what? It does that! 😂

[@GabrielSedlakOfficial]

It's not easy to always find all the feature for sure and the dealers miss a ton as well.... Thanks for the comment and for watching 👍

[@ndocds]

a lot of these features my 2015 ram has...

[@AnmonRah]

Set to wumbo Check the following distance at length

[@KuzFuz]

I wish they'd allow you to drive with whatever lights you wanted still on.

[@diydozier3205]

These features were already on the 2020+ models. This isn't new to 24. Just saying. Also you stated on "this Denali Ultimate". It is available as an option on an SLT, Denali and Denali Ultimate.

[@GabrielSedlakOfficial]

The one I had before this one was a 2020 AT4 2500. Appreciate you pointing that out! Agree some features might be available across trims. 👍 Appreciate the comment 🙏🏼

[@denverampalo6234]

great

[@GabrielSedlakOfficial]

Thanks for watching! 👍

[@bohenderson125]

🔥🔥

[@johnnunez3451]

B&W makes a drop hitch for that tailgate. Won’t hit

[@remingtonp1k52]

Yes they do! Im getting one soon

[@GabrielSedlakOfficial]

Hey, appreciate that I’ve got a check it out. Thanks so much for watching and for the heads up!

[@jonathonsantamont8527]

B and W is top shelf stuff…. Nice!

[@coryohanlan194]

I love that B&W hitch, BUT, when you have the tow ball sticking out that feature does help

[@Pom1-cy]

I just brought a 2024 2500 AT4 and was wondering about that

[@gallardo360]

one feature that is not hidden is the 100k + sticker 😂

[@skipads8784]

😅 It's not that much when you trade in last year's.

[@gallardo360]

[@RyanHadden-nj8pb]

I pick mine up in a week and a half

[@GabrielSedlakOfficial]

COME ON!! That's AWESOME! You will Love it! What color/specs did you get?

[@greghewitt8117]

If most people read their manual, you will know about all of these features. Also, you can stow or open your floorboards in the settings so you're not having to hold your foot on them if you drive through a car wash which you wont be able to do as they will stow once you jump in.

[@SuperDaveTX1]

Highly suggest NOT driving through a car wash!

[@GabrielSedlakOfficial]

Agree reading that helps.. 🤪 The stow feature is GREAT! Appreciate the comment 👍

[@semperfi1833]

Which the dealer told me about the tailgate and tow ball drop will kiss each other and make a nice dimple in my tailgate. Thanks for the video

[@GabrielSedlakOfficial]

Thanks so much for, yes getting the right trailer hitch is Critical. I think there’s a company called B & M bumper, and hitch that has an adjustable trailer ball that one of the viewers mentioned works great 🙏🏼

[@GabrielSedlakOfficial]

Correction it’s actually BWtrailerhitches.com 😎

[@shane3878]

Have you backed into a bush yet? Even a bush will set off the fender bender indicator.

[@XtraCryspy]

Why would anyone want that chime so damn loud?

[@GabrielSedlakOfficial]

Exactly! 😵‍💫 😁

[@jonathonsantamont8527]

Only if you are hard of hearing. Only reason I can think. Some of my family that have been around heavy equipment their entire lives, will have that chime cranked so they can hear it…

[@saywhat6250]

WHY FOR THE LOVE OF GOD WOULD THEY PLACE THE DEF TANK RITE NEXT TO THE FUEL TANK, IS BEYOND ME! 😂😂😂

[@marcmo7138]

It is way better than under the hood like it used to be.

[@envyuslawncareservicelands8095]

Quite obvious why they put it next to the fuel tank for more convenience

[@danielk1898]

I also have that truck

[@GabrielSedlakOfficial]

SO AWESOME! Excited to see the truck market get better and better! Thanks for watching 👍

[@searay2085]

Multi function tail gate is wonderful until you smash it on your ball hitch Dammit!!!😢

[@aperturextc]

With all due respect, I’m seeing a lot of of these videos about “hidden features“. All of this is in the owners manual. I guess people just don’t read the instructions when they buy something that’s between $70,000-$80,000.

[@GabrielSedlakOfficial]

I totally agree... read the manual! It's all in there! 🙏🏼
