I bought a new 2024 2500HD AT4 on 11/15/23 - loved the truck except for the puddle of coolant it left on my garage floor. Took it to the local dealer who replaced the oil cooler - once home i discovered it was still leaking from the same place. Took it back to the dealer who had to order another oil cooler back on 12/14. I have been waiting since then with no estimated time of when the part will arrive. I have been without a vehicle for 53 days now and GM Customer Service keeps giving me the runaround. To say the least I am disappointed in the truck but extremely disappointed with GM and in the manner in which this has been handled.

2024 GMC Denali Ultimate

I purchased and still have a 2024 GMC Denali Ultimate that I have had nothing but issues with since the second week of purchasing new. The truck left me and my family stranded in Walsenburg Colorado with only 1,253 miles on it. We called On Star to have a wrecker take it to the dealer. On Star wouldn’t send a wrecker because we had a 22’ utility trailer so we where out a wrecker bill. I called Ferguson GMC where I purchased the vehicle from and left multiple messages for my salesman and the GM to see what my options were. I never received a call or text from either. One week after the day it broke down I did get a call back from the service manager MIKE GENOVESE . Mike informed me there was nothing they could do since it was already at another dealership. The truck was taken to Wilcoxson GMC in Pueblo Colorado where it sat for 6 weeks getting a new DPF filter and Pressure Differential Sensor. GM has still been unwilling to compensate for the 6 weeks of being with our primary vehicle used for work. We literally had to purchase another New GMC from Wilcoxson to get home as there where no loaner vehicles available. When our 2024 GMC showed up at our house through GM reunite program it had 680 miles more than when it was delivered to the dealership and there was no diesel or def fluid in the truck. We finally got a reimbursement check for the hotel room we had to get for 2 nights waiting for the dealership to open. I wouldn’t recommend buying anything from General Motors as they don’t stand behind anything. I have spent over 40 hours trying to get a fair compensation or Buy Back from GM and have yet to get anywhere with them. I was told they would Repurchase it and was told to get in contact with MIKE GENOVESE the service manager at Ferguson GMC in Norman Oklahoma. I called Mike to schedule a time to bring it in for the Buy Back and he didn’t know anything about it. So I called Shaun Gusumano back and he assured me Mike was brought up to speed and would be handling it. Once again I called Mike and still isn’t aware. If you are having any issues with getting ahold of GM please let Shaun know as he is not taking care of my issues. [contact info removed]

I love the truck! Looks great in factory blackout aka Black Diamond Edition Denali. I have had a couple of quality issues and it has been in the shop twice but other than that it is well built so far with 20k on it. GMC builds a good product but really needs to work on customer service. The truck is man made so it is going to break, they really need to work on how fast they can get the parts to repair the vehicle. 3 months to order and replace a factory rancho front shock is ridiculous.

Still new but love the technology and the ride. I will report more after I have more miles driving it. It is not my daily driver so after 6 months I have only 1100 miles on it. So far so good it drives great, loads of acceleration, comfortable what else could you want. It’s big so naturally it is cumbersome to park but the cameras make that manageable. The only knock other than too much plastic in the interior is with the big tow mirrors there is a blind spot when looking to the right towards the roof pillar. That’s because the tow mirror is right behind it and that blocks your view. It is not unworkable but a minor annoyance just the same. After a year of owning it still only an occasional driver with a little over 3000 miles on it. I took a camping trip and it pulled my 25 ft camper with ease. It really shines when towing and you have an appreciation of the trucks size and power. So far the only negative was on that trip my HUD quit working. A minor annoyance and when I take it in for service I will have it fixed. Well as it turned out the HUD didn’t fail I apparently didn’t realize I accidentally turned the HUD position too far down and didn’t know how to turn it back up. So basically operator error. I still have a little over 7 thousand miles on it and have taken it camping a few times and it pulls my camper with ease. Bottom line is it is a great truck. I am a little embarrassed to say the HUD issue I posted in the review turned out to be operator error. Somehow I must have bumped the button that positions the HUD display up and down and turned it all the way down making it disappear from the windshield. Anyway it was working all along so moving right along and like I mentioned before it is not my daily driver. I have a little over 6k on it and zero problems. It drives and rides like a dream.

Totally disappointed with the truck, has been back to the dealer 3 times in the 6 months that I have had it. Don't spend the money isn't worth it, bad fuel mileage, GPS and Satellite radio lose signal all the time, the transmission doesn't shift correctly. Had my previous Denali for 8 years no problems, the new one is disappointing! They have corrected most of the issues, but still have on and off problems, for an Ultimate Denali it is a disappointment!

2024 GMC 2500 Denali Ultimate in my opinion AVOID

In my opinion, I would steer clear of this truck. I purchased a 2024 GMC 2500 Denali Ultimate in April 2023, and it's been nothing but trouble since. The truck has spent over 90 days in the shop, yet they still haven't managed to resolve all the issues. One major problem is that it consistently fails to start after being parked in the driveway for more than nine days—regardless of the weather conditions. For instance, it died on a 30-degree day after just three days of sitting idle, and within nine days when temperatures were above 40 degrees. On top of that, there are numerous electrical glitches. Even the supposedly fantastic feature of the kicker radio is problematic—it remains connected to your phone when the truck is turned off, and the only way to shut it down is by disconnecting Bluetooth from the truck. Furthermore, the traction control is highly unreliable, and the trailer brake control loses functionality while towing, making it incredibly dangerous. What's the point of boasting about towing capacity when the vehicle becomes a rolling deathtrap with no brakes? #buyford #GMC #AngryDenaliOwner

Purchased due to obtaining a travel trailer and needed payload which 1/2 ton could not provide. Went back and forth regarding diesel or gas. Ultimately, my son advised the obvious that I should get the right tool for the task and not try to cheap out and “try to make something work”. I came from decades of small cars including a 911 and feared the truck couldn’t be used as a daily driver - properly equipped, it works as dairy driver. One must get the package with cameras which show exactly where this beast begins and ends; with the cameras, it is maneuverable in all parking lots - without the cameras, it is not viable. I use them every time. As a tow vehicle, it cannot be beaten. Retractable towing mirrors, tow mode, exhaust brake, brake controller, tire pressure sensors for your trailer, too! You can see everywhere when towing and lane changes are effortless with camera view integrated into turn signals showing if someone is occupying the space you wish to enter. As a truck, it is comfortable enough for me to use as DD. Diesel fuel discount cards make it much cheaper than premium gas. I have owned over 50 vehicles and this is my wisest purchase, yet. Lots of room to spread out in all directions. We have no issues with our ventilated Denali seats - over 7,000 miles in nearly 3 months. There are different leathers and seating surfaces, depending upon the trim level.

Love the big white durmax diesel, allison 10 speed trans and upgraded interior. Bought used with around 12k miles. Once out on the highway at ~75 mph i can get 23 mpg with this big boy. Do not like the fact that the A/C seems to take forever to engage (2-5 minutes sometimes) but will run you out once it "decides" to come on. Ventilation in the seat cooling is minimal compared to previous F250. Steering is very light all around and wish it were heavier at speeds. Stereo is OK, but could be better IMHO. Controls are OK for me once getting used to and i use factory as well as android auto. Truck is very aggressive looking and has all the tow power anyone would want. Very quiet for a 3/4 ton diesel and the turbo will make it scat for sure. It has a dozen camera angles and provides various trailer views when towing and changing lanes. Had never driven one before i bought it but overall very pleased. Have had zero issues.

The truck, an AT4X HD, has been great so far. It rides better than a regular GMC HD diesel on the highway and handles off-road bumps much more smoothly. The 35” factory tires fill out the wheel wells better and give the truck a more balanced look, IMO.

A solid work truck, not a daily driver

As I said in the title, I didn't and wouldn't choose this truck as my casual daily driver. The ride is definitely a more bouncy, "vintage" truck ride compared to the 1500, F150 or similar class trucks. It's also large and not the most maneuverable. The hood is wide and long which affects front visibility. That said, I am very happy with this truck. I pull a 7x18 work trailer with this truck at a little over 3,000 lbs. It doesn't even break a sweat, and the adjustable tow mirrors are great when backing it in. I have the cloth type seats which are actually pretty comfortable for a lower trim. I have the larger screen infotainment which is excellent when using navigation. The ergonomics are good overall. The column shifter seems to be designed for a light touch, so it feels a little flimsy at first, but I got used to it. The multipro tailgate is a cool feature, though admittedly I don't really use it much yet. I will suggest getting running boards, because it is a very tall vehicle. I'm 5'7" and before I put on some aftermarket drop steps, It was a little bit of a hop to get into the cab. There is ample power from the gasoline engine for my needs. It wasn't worth the added cost to go diesel, but if you are towing heavier loads then it may make sense. All in all, there's a lot of convenient features and it was an upgrade from my 2013 1500 series that I traded in. It's a great overall package for a work truck. I just wouldn't want to have to deal with grocery store parking lots or parallel parking as your only vehicle.

Beautiful truck( burgundy color). However the most uncomfortable truck to drive. It had a spot on the floor board to the left and it’s so uncomfortable to put your foot there. The pedals are uncomfortable as well. My leg actually cramps. Our son 21 year old som took it on a trip a few states away to get another vehicle and he came home & said he wouldn’t drive it again. The seats were uncomfortable too. The cup holders which there are plenty thankfully we use them all but the arrangement isn’t great. They should be side by side instead of in front of one another. Again our truck is gorgeous but no one wants to drive it. We have an 18 High Country which is comfortable to drive. We actually just went and bought this without driving because we loved the look but had no idea the driving part would be so uncomfortable. Plenty of leg room in front & back seats. The mirrors we still haven’t got adjusted correctly. I do love the cruise control option that goes along with Traffic so we don’t rear end anyone. Really of they fixed the pedals & the foot ramp on the left it would help tremendously. It’s needs some of the old style comfort for driving. Love the heated back seat. Everything else I like.

7K on my truck with no issues at all. I sank it in the MUD and had to get it out. The Tow Truck Drivers (2 trucks) said the frame was the strongest they’ve ever seen. The truck has the best stance and it can do anything I want it to. The seats are not as comfortable as my old King Ranch but I have found a happy place. Love the truck, would consider GMC from now on

First of all, I would never voluntarily drive that, but I got issued the (probably) cheapest truck available, so now I'm stuck with it. Otherwise I can't explain how in the world where Dodge, Ford and Chevrolet exists, somebody would pick gmc. Ergonomics is absolutely horrendous. Seat is too short, shallow and firm, it feels like a stool (in every meaning). Steering wheel doesn't have telescopic adjustment, so it's too far from the driver. Interior lighting shimmer in the night, causing extreme eyes strain. Headlights beam is too narrow, and spectrum is so bad you have problems distinguishing white from yellow. No idea about reliability, hope it breaks in half soon.

I purchased a 2024 Sierra 2500 HD and love this truck! I have not had any issues with this truck. Its beautiful and rides very nice for a 3/4 ton pickup. I never thought I would describe a truck as beautiful but this one is. I get between 13 and 16 mpg. Mine is an SLT with pretty much every option so it wasn't cheap but i feel its worth the price.

I love my truck so far have 4000 miles on it with no issues. Mine is the 6.6 gas with 10 speed Allison trans. For a 2500 this truck rides very nice. I'm getting 15 mpg and was only getting 20 in my 1500 5.3 that i traded in. Mine is the slt and has every option but the sun roof. I looked at fords and they just did not compare in fit and finish and luxury.

Purchased my 2024 GMC 2500 Duramax Denali ultimate in February 2025. It was a demo, and 10k off MSRP plus had a bed cover and other cool additions. I got it at Sangster GMC in Wenatchee, WA where I’m retired and reside. I got a decent and fair trade on my old truck and the deal was so professional and respectful. No crazy games. I recommend getting the extended warranty which I was able to negotiate the price which made the deal even sweeter. I really wanted to buy from Sangster as they have been in business over the past 50 years and they are a huge part of our community here. I love this truck including the total look and stance of it. I love the larger touch screen and the auto start too. I’m planning to tow a 27’ travel trailer. The truck can tow it no problems with the torque from the 6.6 L diesel engine. I like the interior design and the exterior slate gray color pops with the beautiful chrome grill. It came with the 20” wheels and Goodyear A/T tires which I love as well. I’m 64 years old and this truck is my dream ride. Driving it with the radio playing reminds me of cruising in high school. Did I mention the turbo boost can push you back in your seat! The other day I was driving with my gal and the classic rock playing on Sirius XM and I thought it doesn’t get any better than this… I feel for those who haven’t had such a positive experience, but I love my truck and am grateful for owning and driving it. Thank You GMC!👍🏽♥️

Next time, I will be more thorough before purchasing but when coming from a Lariat F250 to a Denali, I expected most of these things to be a given. 2024 Denali 2500 Lessons Learned: 1. Motor has a constant tick 2. Steel body shows rust when paint chips 3. Infotainment system is not user friendly 4. Infotainment system is partially blocked by gear shifter 5. Can’t use tailgate step with trailer ball 6. Fog lights do not add additional light 7. Fog lights do not stay on automatically after they are turned on 8. Automatic step LEDs look cheesy compared to rest of truck lighting 9. Dead spot in the gas when taking off 10. Valve body is a known issue with no repair in sight 11. Wheels have plastic trim on the face of the wheel and feel cheap 12. Frame coating peels off with hand to exposed metal 13. Cup holders do not hold large drinks 14. Does not include sunglass holder 15. Small center console storage 16. Leveling kits are hard to find without sacrificing ride quality 17. Speakers do not put out great sound for a Denali 18. No keypad to get inside without keys 19. Steering box hisses when turning 20. Push button on door handle requires two pushes in most cases to work 21. Trailer lights stay on all the time when connected to truck 22. No physical camera buttons. Must go through the infotainment system 23. Carpet wheel well covers warp after driving through rain and do not straighten out 24. Back seat AC does not put out enough to keep kids from physically sweating 25. Passenger mirror is at different angle from driver the driver side mirror 26. Truck downshifts too fast when coming to a stop 27. The seats are hard and uncomfortable on long rides
