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

Bought the truck new in 2023, first problem def gauge malfunction, google computer malfunction , power tailgate open at random while driving down the road. And let's not forget the grand finale you must purchase a data plan to use most features in the onboard computer, but everytime you get in the truck the phone barely works and you lose all communication services when driving from northern Nevada to southern california. Truck looked great until it wasn't. Gone now traded it in for a ram 2500 diesel

I purchased a NEW leftover 2024 GMC Sierra 2500 PRO with 6.6 litre duramax with Allison 10 speed transmission. I bought truck at end of April and 5 months later....I discovered it had been leaking transmission fluid, motor oil AND coolant. I only had 2000 miles on it and had to add a full quart of oil and knew something was wrong. I took it to local Chevrolet dealership and they found multiple factory mistakes. The transmission had to be removed to replace front leaking seals. The oil sending unit had been leaking ever since I drove it new off the lot. And the thermostat housing had to be completely replaced, as it was not "seated" to the block mount and was leaking coolant. The dealership took 2 weeks to make repairs. I contacted GM headquarters in Detroit and told them I wanted them to purchase my truck back or trade for another new unit. I have been getting the run around from my GM consultant and still my truck issue is NOT being addressed. Apparently you are only a valuable customer when you're buying the overpriced vehicle, but if you have a problem they want to patch it back together and hope you go away. Given all the major flaws that this vehicle had from the factory, they should have NO problem replacing the product or refunding my Money!!
