2025 GMC Sierra 1500 consumer reviews

I wouldn't recommend GMC as a company. WE bought this 2025 because the 2022 we bought broke down with 29k miles on it because the 6.2l engine seized. We took this truck to Alaska and was coming back and stopped in Kalispell, mt to go to Glacier NP. We got in the truck and it wouldn't recognize the key fob. We took it to a GMC dealer (Corwin Motors) and their service dept was awful. They had no idea how to fix and they finally told us they were done working on it. we were 2500 miles from home. We had to buy another truck (3rd in 2 months all GMC) and Corwin low balled us very badly on trade in value knowing we were in a desperate way to get home. SO we bought another truck and headed home. As soon as we got home we traded the 2026 Silverado on a 2019 Ford F150 and love it....

Let me start by saying I have the AT4 model with the Duramax 3.0L diesel. I had a 2024 Elevation with the 5.3L V-8 that I bought to pull my 22’ camper. While the Elevation pulled my camper fine it drank the gas like it was on a binge. And with a 26 gallon gas tank it seemed I was filling up every couple of hours. After one trip to Nova Scotia I knew something had to change. I pulled my camper out west to Yellowstone and back through Arizona. It pulled like a champ and fillups were a lot more manageable. Even driving the speed limit out west I still got four to five mpg better than with the gasser. I liked the Elevation but I love the AT4. Way nicer ride and great handling. I get 30 per gallon of diesel on the highway if I drive the speed limit but I got it to tow with. I added a Titian replacement fuel tank so I have 43 gallons instead of the 26 it came with.

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?

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.
