New member, long-time GM/GMC owner. Z71, Tahoe, Yukon Denali, etc. GM homer for a long time. I'm going to post this more to get it off my chest because my wife has told me to stop complaining to her. It is simply my take on having this vehicle for a short time. Many gripes are minor, I agree. Some may be I missed something in the poorly executed menu/option arrangement. Maybe some will be addressed in updates. But this is a RANT so if you don't want to know what they screwed up on this truck move on.

Received my 2024 2500 AT4 about a month ago after waiting 10 weeks or so. 2000 miles. Duramax. Not many extra options (5th wheel prep, bed mat, cover, etc.), it pretty much has everything you'd want in the AT4 package to begin with.

First impressions:

  1. It is a big, beautiful vehicle. It is a visually well designed. The front end changes are impressive. I get compliments everywhere I go.

  2. The truck is very comfortable to ride in. Good armrest heights, comfortable seats, good visibility, cold AC, etc. Several 4+ hour trips and I've been content the entire way (mostly, see below).

  3. Fuel economy wasn't my target with this truck (obviously) but despite not being broken in is getting right at 18 mpg mixed driving. Sweet spot is between 55 and 62 mph where it just doesn't seem to have to work to keep those speeds.

  4. Can't comment much on towing, I drug my 24' CC a short hop and it didn't even know it was back there (~6500#). Plenty of power and acceleration from the Duramax.

  5. Step locations, exterior fit and finish, etc. seem well thought out and built.

But now the stuff that is probably going to make me move on from this truck in short order. It seems like every day I find another GM oversight, shortcut or outright failure. I've had several "normal function" issues the dealer won't address already as well. Brake pedal has 1" of pure slop, and slaps. Tap the brake - SLAP. You can't even really tap the brake because the first inch does nothing. Every time. Supposedly it is the shifter release which isn't true because this is driving, not to release from park to a gear. Cut the wheel hard at slow speed it squeals - like a belt squeal. Again, supposedly normal function (for a 30 year old Plymouth maybe). And yes, I know the "tick" is normal but why make all the effort to quiet the diesel exhaust only to create a typewriter on a bullhorn. If you are near anything - wall, car, divider, etc. it is obscene. Cut the truck off at the drive through, because you can't talk. Get away from the divider unless you want to Chinese torture your mind with ticks inside. Have people stare at your beautiful truck making the most obnoxious sound at idle. You can hear it clearly from a football field away. Perfectly normal I'm told, glad my exhaust is a little quieter.

Bottom line the vehicle technology is AWFUL made worse by the broken Android based interface. GM blew it, IMHO. Does it look pretty, sure. Does it work or did the engineers actually think about anything besides slapping a wide tablet on the dash - no. This is not a technology package designed for the truck, or really for any vehicle. It is just a basic tablet with a few options stuck on the screen. I can't even describe what the interface is. Android v.10?

1. Instead of designing the truck for the column shifter they simply took most of the 1500 dash and threw it in. The result, the column shifter blocks the left 1/3 of the nice new screen. It interferes with the physical home button, volume knob and completely blocks the first two radio presets and digital home button. This is a major bust.

2. Because this tablet is equivalent to a 4 year old Amazon Fire HD in kids mode, of course you can't change locations of the home button or retile your screen. Left side are the menu buttons, home is fixed. Station presets are locked to the bottom.

3. Then inches of wasted screen space - SiriusXM album covers are a 1.5" thumbnail. And you've got 6" inches of nothing background. Cameras, although amazing don't fill the screen either.

4. Hope you like a clock or Google because those are your only options for the right 1/3 of the entire screen. An ANALOG wall clock or GOOGLE. In red, no color choices for you. If I could just move that to the left side behind the column shifter it would make sense, but no. This is your screen, this is how we divided it and you will like it. Sad.

5. It tries to force you to Google at every option. So reluctantly I tried to link my Google on the screen, via phone, etc. 20 attempts (different wifi connections, etc.) - it will not connect (failure errors) so no new apps. Android Auto means you have maps and Pandora, that is it. And you've got to dig into the menu because Maps mute (phone or truck screen) doesn't actually mute navigation, you have to deactivate any notifications which then kills other Google Assistant features.

6. Want a text message read aloud? Good luck - usually it says can't connect. Until 4 minutes later when it then proceeds to read you something like a voicemail. "You have a new message from yada yada yada...". You get an extra 15 seconds of information you already acknowledged on the screen read aloud in computer voice. Oh and I hope it doesn't have an attachment because it will read the entire background filename as well. We died laughing as this joke GM tech read a picture text .jpg in numerical format starting at 9 QUADRILLION down to the last digit. 2 minutes easy. Even threw in the " dot j p g" at the end. Simply embarrassing GM! On screen notifications stay there until the screen is touched. Read a message, mutes your radio (obviously) but it doesn't return after reading the message. You have to hit the steering wheel mute twice to get the radio to return - this is true of any option that uses the vehicle speakers (bluetooth, voice command, etc.).
 

7. Instead of changing the center area by the cupholders they just cut corners and left you with a giant brake controller consuming half that valuable real estate. In 20 years I've used that thing twice on my vehicles, probably wasn't needed either time. Total cop out instead of finding a proper dash location. But hey you get the half inch deep former 1500 shift lever pocket that is worthless. What goes in here? Fits a can of dip maybe, or the truck key. That is it. Could have easily been any number of useful things. Unreal laziness on the part of GM.

8. Look, USB and USB-C tucked in an awful place! Right beside the cupholder. One beverage tip and those are DEAD, not to mention the cord now sits in the middle of your storage area. One tug or bump and those will be loose and shorted. Simply the worst place in the truck you could put those. They won't last a year. And yes, you will cut your hazard lights on multiple times reaching down into the main storage area to grab anything because they put it right there, in the middle, where you would store and reach for anything.

9. Upper glove box rattles and opens maybe 50% of the time. I haven't even had the heart to dig into that yet.

10. Sliding back window (an upgrade I think). GM probably took a 1500 window/mechanism and slapped it in because the window is half size - meaning you have border/plastic (not glass) taking 25% of the bottom and 25% of the top. Mini - window. Another example of laziness on the part of GM.

11. All of the little cute rubber bottoms GM threw in pockets, door handles, cup holders, etc? GONE if you run a vacuum. Nothing is affixed, just thrown in there.

12. The cameras are a highlight of the truck EXCEPT it has the smallest rear view mirror (and digital view) I've seen in a while. It is smaller than my wife's sedan. Minor gripe I suppose but I can see where GM would cut 40% of their mirror size because it had a digital screen in it and they wanted to save money. And as I mentioned before they don't use all the bi screen either, maybe 2/3.

13. Have a trailer and put on your turn signal, get a great blind spot turn view on the screen. Want that just when you are driving the truck in a tight area or heck down the interstate and want some extra blind spot verification? Tough. Can't seem to get that to be an option unless I have a trailer attached.

14. Use a carwash and want to deploy your running boards? Be prepared to get deep into an Android menu somewhere. Meanwhile there are a few blank physical buttons that could have easily controlled that.

15. Speaking of the running boards. Getting in it is fine. Getting out, more than half of the running board is UNDER the truck. They don't deploy far enough to be anything more than a heel catcher getting out.

16. Nice digital dash with ONE color option and 3 ways to customize. No image capabilities (album thumbnail, blind spot camera, etc.) - just one of the presets GM decided was enough for you and text.

17. Tiny little round lock knob on the door. But they just couldn't bring themselves for that to be flush or fully down when locked could they? Feels nice on your elbow if you want to put your arm out of the window.

18. Buried lights, 2x 4x and hud controls down low or behind the wheel. Learn it with your eyes closed because you can't easily see any of them.

19. Like the lumbar adjustment? Good, because in and out is all you get - I guess we are all shaped the same because who needs to move that up or down at all? They had this option 10 years ago, why was it removed?

Alright, I'm done. I feel better I guess. Just confirmed by typing this that there is no way to fix half of this stuff GM screwed up. Been looking forward to this truck for months but sadly it is time to move on. Good luck to those who have and love these trucks, they are impressive in many ways but for me GM simply cut too many corners and made too many poor decisions that center directly around how I interact with the truck in almost every way.
 

I agree with your assessment on the Google Android system. It sucks more than the intake of an F16 jet engine at full throttle. Also, the shifter blocking the display is just embarrassing, and will annoy me every day for the next 7 years I own this truck. That is so Ford-like, it's nauseating.

Before you dump that truck, take the other truck models for a long drive and hang out in the dealerships parking lot using all the controls for a couple hours.

When choosing a 3/4 ton truck, you're never going to get the refinement of a top tier escalade. I spent a lot of time driving every make, model, and trim of every 2023/24 3/4 ton trucks on the market. You are not going to find anything that you won't find that many complaints with, If you go looking for them. The Ram and Ford both have ridiculous annoyances, and the (not even 3/4 ton, but had to try it) Tundra is the worst. There are so many nanny controls on the tundra, I'm not even sure you still own it after you put in it drive. As for Nissan, I can't even call that a truck....

One of those other models, while testing the info system, actually brick'd my new iPhone, deader than a doornail. Had to drive 80 miles to an Apple Store, and got stuck with a refurb'd one. Grrrrr!!!!

We all expect more from $80K truck, but they are truly heavy duty, which is an enormous expense that eats up a lot opportunity to install the refined aspects of other types of vehicles. I would be sounding like you more if it was a >$100 Denali, but not the OffRoad AT4.

I'm not criticizing you at all. I think you are just realizing where this massive inflation (that the media is watering down or outright ignoring) is hitting us.
 

I don't have an AT4 HD, but a 23 AT4X. Some of these issues I have noticed also. The "tailgate down" button right where you accidentally hit it all the time. Just a disaster waiting to happen for those of us that pull trailers, or have stuff in the back of the truck (I am a contractor) that will fall out while driving. Why in the hell would the tailgate go down while driving anyway? I got the GM box web thing simply because I can't risk losing thousands of dollars of tools out of the back of my truck in case the tailgate down button is accidentally hit.

The operating system is a bit slow. I blame GM for using outdated OS and not an optimized OS. Android is fine, but you can't be running 4 year old OS stuff. Plus you need to have a good enough mobile processor/ram/etc to not be laggy, and I don't believe that GM is using stout enough processor/ram/etc. I have a carplay box (usb-C in as an apple airplay but runs full Android) as my full time operating system for most things. Yes, even this is a little laggy/slow, but it gives me tons of more options - full android and any android app can be installed and used as normal - to be able to use the big display for. I do wish one could maximize the display and get rid of the right 3rd being a clock or smaller nav maps. However, I use Nav a lot to get to different/new jobsites, so I utilize the right 3rd as my Nav map quite often. Not a huge issue or deal for me, but would still like to be able to maximize the main screen for the full display if I wanted.

Starting this past friday, my rear camera mirror started glitching. Half the time it works, half the time now it doesn't. I suppose I will have to take it in the GM if it keeps doing this. Plus, the night time view on my 23 AT4X rear view camera mirror is not nearly as good as it was on my 2020 AT4. Odd.

There are other things I am not very fond of, but overall this is a very nice truck. No manufacturer makes a perfect vehicle, and I still like the looks of the GM/GMC's better than other brands. All of them can be made to look very nice with wheels/tires/lift or level/etc. But still like the GM styling the best, been that way since the 2008 GM body style became available.
 

Thank you for the information. I’ve been on the fence about a 2500 AT4 or just being simple and waiting for the 2024 1500’s to go live. I would like to offer one piece of advice about the power fold out steps. If I’m not mistaken…… to keep the step deployed without digging into your settings…. Simply open your door to deploy the step. Stand on it or keep pressure on it with your foot and close your door. The step will stay down until you reset it by opening and closing your door again. Apparently this is a feature and it won’t mess them up. Please look into it before trying.

That button works while driving???

Yeah I read about that. I'm thinking about going thru an auto wash. Deployment from inside.

Yes, it will drop my tailgate while driving. I have always thought this was a stupid design, now it seems it is NOT supposed to do this, which I did not know.

Not related to the tailgate dropping, but my kicker BT stereo quit working also. No idea why, it just doesn't turn on. And my rear camera mirror is on the fritz since last friday. Will work sometimes, but often has lines running through it, then will turn off. Then at times come back on. A trip to the dealer is in order soon I guess.

I might give that box a try. Thanks for the tip.

Appreciate your experience with the other makes. I was in a 19 Ram 1500 Limited for the last 4 years. Zero issues and I truly got spoiled with the tech, screen, interface, ease, layout etc. I guess I thought a 24 would up that game not go backwards a few years. And I'm an android guy so the fact they don't work together boggles my mind. I didn't go back in a ram because for the money there were zero updates but I'll still argue my Ram smoked the AT4 tech wise even being 5 model years older.

But I agree there is a ton of cost in the power, drive train etc. That being said i don't feel like this is all a lack of them stripping features to save cost it is just failing to make all the ones they added work or testing them properly IMHO.

I think the drop while driving is a malfunction. Worst case I'd disconnect the switch if possible. That would be a disaster waiting to happen.

Keep us posted. Thanks

Yep, I was dumfounded that it would drop while driving. Just thought that was how it was supposed to work on everyones, so didn't realize mine was malfunctioning. I am often looking behind me while driving to make sure the tailgate is up... which is dangerous to do while driving turning your head around like that.

I would venture to guess I have found the tailgate dropped while driving at least 20 times, so that means at least 20 times I accidentally hit the button on the dash and didn't know it. I do have the GMC mesh/web thing that straps between the tiedowns in the tailgate as a kind of remedy, so that if the tailgate is down my tools, compressors, etc don't fall out the back. But damn, it is a scary proposition to have driven, park the truck, then see the tailgate had been down while I was driving.

Yeah, it must be some sort of malfunction. I just drove around the neighborhood trying it out. My tailgate would not drop unless I'm in park.

Are you just assuming you hit the button? I'm wondering if something entirely different may be causing it. Mechanical or some bizarre electronic problem sending the signal???

I just traded a 2019 Ram 1500 for a 23 AT4 HD. There are so many things that were standard on a Ram Laramie that aren't included in preferred At4 package. Honestly, I need the 2500 and Ram didn't have a gasser anywhere near me. I figured what the hell! Other than Android Auto, this truck has less tech and options than my 2014 Ram 2500 did. And it really is 1st world problems. Sunroof: you cant go from open to tilt and vice versa. You have to close whatever option you are using then press other option. In the Ram just press the button you want. Auto sensing wipers on every Ram I have owned since it was an option. Only in the Premium package on the GMC. I do like my truck. I absolutely loved my 2014 Ram 2500 and the 2019 1500 was my favorite truck ever.
