New and used 2025 GMC Sierra 1500 trucks for sale near Rowlett, TX

I hate singing the service for an intermittent issue likely caused by a computer chip, on board computer or software but it a serious issue when the Adaptive Cruise control just locks the brakes up at cruising speeds over 55 MPH. I am hopeful they will eventually figure out the issue. This time I requested they just deactivate Adaptive Cruise as I?m worried about serious injury. The last time the brakes locked up out of the blue, I almost lost control of the vehicle and it slide sideways almost flipping at 70 MPH.

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.

Everything went well did not have any problem. My sales person was perfect with me. Thank you.

Had a great experience there hassle free. Jermey Burrell had everything laid out for me when we got there. I would recommend to anyone. Keep up the nice work.

Wonderful people. Kind & very knowledgble. Would recommend them to anybody.

I wanted to purchase a new vehicle and Terry was the sales man who also sold my mom a car his kindness and understanding made me me feel comfortable. His customer service was spectacular. The finance person was also so kind. I will recommend this dealership to others. They know how to make their customers feel valued.

Great experience from start to finish. Our salesperson, Clayton Haas, was straightforward and efficient, and got us to the price we wanted

Jeremy was incredible and made the process of buying a new car so easy. When it’s time for a new car, he will be my go to salesman.

Robbie, my salesman, was outstanding!! He made it painless and is absolutely customer focused. Pricing was ultra-competitive. Dealership was clean. We will definitely go back.

I've been going to this dealer for the 6 years I've had my Buick. Mary was outstanding and a great employee. Great experience again!

Service was very good. It exceeded all expectations, which were very high to start with. I was met right away at my door and was walked through the whole process. Even on the pick up , I was greeted at the door and helped until I left. I apologize for not responding earlier.

Several sales personal where informative and knowledgeable in customer service. I didn’t purchase a vehicle but will give Vanguard the first choice at sales.

Nice sales people. Easy to work with, but would not move on the price of the car.

Simply Exceptional service once again! They continue to be a renowned dealer who cares about their customers and reputation. Sewell will always have my business for life.
