My 2016 GMC Sierra 1500 SLT All Terrain - Love it!
I've owned this GMC Sierra 1500 All Terrain since it was 8 months old. With the exception of two warranty issues (failing power brake vacuum pump and transmission electrical harness), I have been totally happy with this truck. Up until now, my 1996 Chevrolet K1500 Silverado with it's 5.7L Vortec engine was my favorite truck of all time, this GMC (5.3L LS engine, 8 speed automatice) has earned the top spot now of my all time favorite truck. It is comfortable to drive, and runs as good as the day I bought it over 5+ years ago. I've got 71.5K miles on it. My biggest issue is I wished it had the 6.2L engine for better towing capabilities. Other than that ... love this truck.

I bought this after going to the dealer just to look at
I bought this after going to the dealer just to look at colors. I had a 2016 Chevy 1500 LTZ that I loved. There was my down payment and took this Denali home. Only 2 options. Paint and moonroof. I thought my chevy with 3.42 gears was quick. This one goes with 3.23's. The ride is great. Fit and finish are perfect. My only complaint is this Bose/Apple play radio is not what the 2016 Bose was.

Overall I am very happy with my new Truck. GMC however needs to address their software glitch where the display screen intermittently stops working or the audio cuts in and out. I keep hearing a software update is being worked on but that was a while ago?

Great experience
Such a good experience, from introduction to purchase. They pretty much accomodated all my needs and they do all this with no "dealer fees". I would buy from them again if I can.

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.

2022 GMC Sierra SLT 3.0 Duramax
My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

Failed transmission and full replacement
We have owned our GMC Sierra 1500 for approximately 9 years now. The only real disappointment with the vehicle is that we had to have a full transmission replacement Just after the 100k mile without any warning whatsoever. The truck now has 107k miles on it and now , again out of nowhere, we are experiencing slipping in the trans and the engine light is now flashing. Very disappointing since we are starting to feel uncertain about the reliability of the vehicle now. The truck itself is gorgeous and shows ZERO signs of its age, sporting new rims and tires and a lifted body and no rust on the body at all. We hope there are no major issues with the engine as the vehicle has always been maintained as needed and on time for regular servicing at the dealership.

I have brought my vehicle in for every oil change I have
I have brought my vehicle in for every oil change I have needed. Always courteous and professional, my car gets a diagnostic check every time and is freshly washed. I like that the Service Department send out coupons, and making an appointment is easy online or with a phone call.
I own a 2023 Sierra 1500 Elevation equipped with the 2.
I own a 2023 Sierra 1500 Elevation equipped with the 2.7L TurboMax, and it’s been outstanding. It currently has 23,000 flawless miles. I’ll admit, I was skeptical of the 2.7 at first, but I jumped in feet-first and have never looked back. Living in Colorado, I regularly tow a 5,000-pound travel trailer through the Rockies with zero performance issues. The truck pulls confidently, handles grades with ease, and still delivers impressive fuel economy—23–24 mpg on the highway and about 18 mpg in town. I couldn’t be happier with this setup. If there is a negative to mention, that would be that after three years of ownership, the black wheels havent grown on me, and Im beginning to hate em. :) Lastly, the mpg while towing drops to 9mpg which is similar to that of a V8. All said, its been a great truck. :)

I have the 1500 double cab with standard bed.
I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

141,000 SLT Still Going Strong
SLT with most options. Purchased at 127k. Currently have 141k after 17 months of ownership. The tranny that came with it was not original. I have had to replace ball joints, a/c condenser, brakes, wheels, radiator, a battery and a starter. Can't complain at this mileage. This is one of the quietest vehicles I have owned (that includes Audi A8's) and it's shod with Cooper Discover AT3's that chomp through snow like my Toro snow thrower. I also replaced the stock halogen bulbs with LED's and what a difference! The interior is comfortable, and I did replace the drivers seat bottom cushion. The nav system sucks, it's not very intuitive and it isn't very good at mapping the best route. Besides, I use my sedan for long trips. Phone integration is a breeze. Radio surprisingly decent. Everything works as it should. It's easy to pop the kayaks in the bed and the ebikes on a carrier and head out for the weekend. When moving stuff, I have the 80" bed so I can fit loads of stuff under the hard tonneau cover. The interior still has NO squeaks or rattles. Amazing. The heated seats are slow to heat, and the heated wheel is slow to warm up. But this thing is such a beast in the snow and rain I don't want to drive anything else! All in all a very reliable, well-built, and for the genre a good-looking vehicle. People tell me all the time what a nice looking truck I have. It's stock. Thanks, GMC.

2019 Sierra SLT X31
I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets
