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.

I always use Williamson to service my trucks and they always do a great job. Erik in service is a credit to Williamson. I have purchased 4 vehicles from Williamson. 3 GMC Sierra?s and a Buick.
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.

Tuve un pequeño inconveniente al llegar a cambiar el aceite del buick gx y pude hablar entonces con una excelente persona su nombre es Laura del front desk que Dios la bendiga mucho ella es una maravilla atendiendo al cliente en mis casi 70 y desde que tengo 13años estoy en EEUU les aseguro que existen muy pocas personas como ella. Finalmente pude cambiar mi auto con Emilio y Sergio el financista y han cambiado entre todos una experiencia pasada no de las mejores.. Gracias a los 3 me siento muy feliz con mi nuevo Buick Envista 2026!!!!! Gracias Lorenzo Buick!

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.

I went in on Saturday to lease a new Buick and was taken care of very fast. Yohan Fernandez has been my sales associate for the last six years and I couldn’t be more pleased with his professionalism and how fast and easy he makes the whole process seem. They have a great selection of Buick and GMC models with different options to fit your budget nicely. I will be going back for future sales. Thanks again !!!

My experience with Impex auto sales was absolutely fantastic. Rick Lanier, my salesperson, was so easy to work with. Very responsive and took care of any and all questions I had. The process from start to finish with delivery of my vehicle was extremely smooth. First time customer with this dealer, if I were to purchase another car, I would definitely use them again.
