Bought this SLT model after trading in a 13 2500 HD Denali. Needed to pull a 16000 lb Fiver camper. This Pickup has extreme power and smooth shifting. Thought about getting a single rear tire toner till I realized the only difference was an extra leaf spring is all. I had automatic step sides that come down when you open the door and that made access in and out easy even the wife enjoys it. I have 13000 on it now. I guess I don't see any issue with the headlights seem the same although I did notice at the parts counter upgraded bulbs on the counter so maybe that fixed the issue. I especially like the bright lights in the side mirrors for backing up at night. No problems with the leather or accessories, I did get extended warranty just in case. mileage varies about 8 mph pulling the camper and 17 mpg on the highway not pulling town about 15. Seems like a great pickup more to come.

This is a 6.6 Duramax crew. There was not an option when writing a review. I bought this truck used with 44k miles on it in February 2018 from a private party. This is the nicest vehicle I have ever owned. I have no issues with the headlights so they either were replaced or people are over reacting. This is my daily driver and I average 17mpg. 9 miles to work and mostly in town driving. I love towing with this truck!!! We have a 25’ Travel trailer and it’s like it’s not even back there. I love the exhaust brake and tow button. I am trying to think of something I don’t like about it but it’s hard. The interior is awesome and the seats are comfy. We have taken a handful of road trips already and can’t wait to take more. It has every option except the heated steering wheel. I even have the remote start which is awesome!! I added oversized tires and wrapped the grille and mirrors. I also put a spray liner on both front and back bumper. The rest is stock. This is a beautiful truck inside and out. I get tons of compliments. I will be keeping this for many years.

I’ve driven many diesel powered pickups here at home and abroad for over 35 years. The new, 6.6L Diesel Duramax/Allison, is the center of Sierra’s Universe and maybe a home run for GM against its competition. The new hood scoop design brings conversation at every refueling stop. To bad Edmunds didn’t include any photos of this hood, on their review. This is a large pickup and not a sports car but folks this truck is a thrill to drive. It handles the road seconded to no other heavy duty pickup I’ve ever driven and again I’ve driven many. My wife, (5’ 115lbs), drives this vehicle with ease and can even parallel park. It’s quite ( wind, and tire noise is minimal and no diesel clatter! ),the interior is cavernous, the leather is top grade, the control knobs are large and easy to manipulate, storage and cup holders are everywhere, the infotainment system has been upgraded regularly and the voice recognition has improved. The torque this engine produces from approximately 1650rpms and flat throughout the rpm range makes towing my 12,000lb travel trailer with ease. I can’t wait to go out west and enjoy the Rocky Mountains. I only have 10k miles on it, I may add another review in the future but today I have to hit the road in my 2017 GMC 2500HD Diesel Sierra Denali. I did give it a couple of 4 Stars because, it didn’t have lights in the glove boxes and center console and no automatic up/down lighted running boards but the was easily rectified.
Duramax!

There is no drop-down option for the Duramax Diesel version. Traded in a 2014 Denali 1500 for the big boy. I love this truck. No car/truck is perfect but the Duramax is the best Diesel engine on the road IMO. Sometimes the radio is quirky when plugging in my iphone so I just stream over bluetooth. I've noticed that the power steering takes more arm strength when maneuvering tight spots, more-so than other truck brands. The headlights are a less than great and should be recalled. I am hoping the new headlights that come on the 2016s will be interchangeable. I love my truck. It turns a lot of heads.. especially mine!

This is an excellent truck, I was looking for a diesel from all the American trucks, I test drove all the trucks and read about all of them. All the reviews on GMC Denali HD2500 Diesel Duramax were dead on. I only had one issue when I first purchased the truck which was a leak with my master cylinder. They fixed it without hesitation and also painted the part of the frame below the master cylinder that took out the paint on the frame. I purchased the truck on November 30th, 2016 in Idaho, it now has 42,000 miles, we go back and forth between California and into Canada and everywhere in between quite a bit. First the interior, it's an extremely quiet truck, very minimal road noise. The Denali package is very comfortable, especially when it's blowing snow -26 degrees, you have the heated seats, heated steering wheel and just a comfy truck to drive. The only gripe about the A/C or heating system would be no vents in the back, it would be nice to have that and also more USB outlets in the rear for my kids while traveling long distances. The Duramax engine is an excellent motor, with the Allison transmission, it has lots of power and can pass multiple 16 wheelers without even sweating. The power band is very smooth as is the shifting on the transmission, we recently purchased a property in the NW and had to do some 4 wheeling to get to some of the lakes, it's a big truck but wasn't an issue to get back to these places. The sweet spot on this motor is 75mph, it will get 20 mpg, not bad for a 7,700 lbs truck. I still have the original Good year tires, they still have good life but will need get some winter tires for where we will be. I haven't bought an American car or truck for almost 20 years because of past bad experience with quality, I think all the American brands have really improved and so has GM brand, no complaints, great truck and if you're looking to haul a 5th wheeler or horse trailer, this will not be a problem.

Some painted bumpers do not hold up. Eight months old and my bumper has no less than twenty chips. Some as big as a quarter. The dealer did not want to stand behind it and said don't bring it back here... Wow.

So, yes. The SD card reader is pretty much useless. But all of the storage is amazing. The 6.6 is amazing along with the Allison transmission. I'm getting 17 in town and 20-21 on highway. Towing my tractor around is a breeze almost forget it's behind me. I did read the other reviews and the gap at the tailgate is real, and it does let a lot of dust in, However you can buy a seal kit for it. The safety features are cool. With the vibrating seats, lane departure detection, and back up camera, if you crash and it's your fault. It is actually your fault. bottom line I've owned a lot of vehicles, other than a minivan which I haven't owned but have been in and was amazed at the comfort and room this is the best and most useful vehicle you can get.

I bought my truck as a Certified Pre-Owned Vehicle almost 2 years ago with the primary purpose of towing a 35' travel trailer. It had about 16k miles on it when I bought it and currently has less than 45k miles. We went with the diesel (model in the review says 6.0L since diesel wasn't listed as an option) since we eventually want to get a heavier 5th Wheel camper. I'm now considering getting rid of it due to the number of times I've had to return for service. The check engine light has come on 3 times in the past 2 months (EGR valve, mass airflow sensor and DEF heater). The truck left us stranded out of town with the camper when the mass airflow sensor failed. Besides the check engine light, there was a power steering fluid leak (known by GM due to Service Bulletin) and some sort of known issue with a bad weld on the diesel exhaust that apparently causes excessive smoke. I'm anticipating that being a problem one of these days. Not sure that I can rely on this truck for what I bought if for.I'm extremely disappointed so far and since this is my first time purchasing a GM product, I'll likely not return as a customer in the future.

Picked up a stone blue 2016 2500 Denali from Bayer Motors in Comanche TX. Best truck ever, as my wife says. 500 mile drive to dealer was definitely worth it. Looking for a big loaded truck? Call Jeremy. It’s been a year and this truck has been a real workhorse. Pulling trees and clearing/hauling are no problem. Has been our best truck to date

Be sure to take this truck on an extended test drive. I was in the car business for 30 years and must be a slow learner but didn't heed my own advice. The cabin is very nice and comfortable which is important because we are driving long distances pulling a 5th wheel. Performance and towing capability are good but I think the published tow rating is optimistic. I am pulling a 14,500# unit and feel I am undersized. GMC rates this truck to pull 17,100- it's a diesel. The engine and trans are fine but the suspension is light. My other sore spot is the the sloppy steering. It's light without an load and terrible when pulling. I wouldn't recommend this product and will be not keeping it for long.
