2026 GMC Sierra 1500 review
I bought the AT 4 version. Loaded. Has good ground clearance. It's powered with a 3.0 l turbocharged diesel. Has lots of horsepower and torque. I've had no problem but I talked to my friend who's a certified mechanic and they're having a lot of problems with the engine blowing up at very low mileage. A lot of the time less than 15,000. Some of them have problems with the thrust bearings failing causing increased crankshaft play back and forth to the point where the timing chain and the rubber belt that runs the oil pump can fail. The engine has been described as grenading. They're basically self-destructs. There's a specific power code that indicates low oil pressure and allowed rattle sound before it finally fails. I heard that the engines were on back order, so if you're one of the unfortunates you can plan on waiting 10 or 12 weeks or longer to get your truck back. They have to remove the cab completely to swap motors. But overall I love the truck. It's a big improvement over the 2022 I just traded in.

Weld County Garage GMC Hummer review
Great experience! When I contacted Weld County Garage about a used vehicle, Sales Consultant Miguel Orozco provided exceptional service. Due to my 1.5-hour commute from the WCG location, Miguel provided photos and videos of the vehicle so I could be sure it was worth taking a full day off. I later learned that Miguel had come in on his day off to assist me, a gesture I genuinely appreciate. Having visited numerous dealers in my search, Weld County Garage stood out as the most helpful, professional, and customer-centric. They were not just interested in making a quick sale, but in understanding what I was looking for and finding the right vehicle that fit my needs and those of my family. Unlike many dealerships, WCG encouraged me to take the vehicle to my mechanic for a pre-sale diagnostic check, and all details listed on/about the vehicle were 100% correct. Like many, I have never had a pleasant experience purchasing a used car. However, thanks to Miguel and Craig, the entire process was painless and drama-free, instilling in me a newfound confidence in car buying -- especially with the right dealership staff. Thanks for a great experience, WCG!

I've been a customer of Markley Motors for over a decade. Just traded in my 2017 GMC Denali for a 2025. Hassle free process. Fair. Great trade value and always top-notch service. I'll be back.
2026 GMC Sierra 1500 review
This is my first GMC and I absolutely love my Sierra 1500 Elevation. The 5.3L v8 is more than enough to pull my camper, I love the stylish interior and it is comfortable to drive. I also felt with the financing and discount specials this was a great deal.

Laura Buick GMC review
Nick Pashos did an amazing job taking the time to make sure I was happy with my purchase. Michael Minner was great in finance with explaining all the details and working with me financially.
2026 GMC Sierra 1500 review
A little expensive, but comfortable, quiet, smooth ride. Great performance out of the 6.2L and better than expected fuel economy in the low 20s. Outstanding interior and good looking exterior, especially in the Downpour Metallic color. I don’t have 700 miles on it yet and have owned it for 3 weeks. Therefore, I can’t pass judgement yet on the reliability, but so far I am very satisfied. This replaced an 8 year old Ford F150 that served me quite well with only a couple of issues in the 100,000 plus miles.
