New and used 2025 GMC HUMMER EV SUV SUVs for sale near Lucas, TX

They say the most loyal customers come from ones who have an issue and the company makes it right, even if it wasn?t their fault. This couldn?t be more true with the service department at McKinney GMC. They took an issue that was not their fault, and fought alongside us to get it rectified and ensure a positive outcome for us and I will be forever grateful for John, Rob, Amanda, Caleb, and Victor for putting in the extra work to help get this resolved successfully. We just picked up our vehicle after it being in service for 5 months, to no fault of the dealership, but due to an issue with the insurance adjuster. Our vehicle had shut down due to what was later determined to be contaminated fuel, but the insurance adjuster made a mistake in his findings, and denied it. The service department answered every question, provided every document, picture, and detail I requested as I was fighting this with insurance, and let me tell you, I requested a lot. And they did it with grace, even on the days I sat in their dealership for hours on end collecting things. We had also contacted GMC/GM customer service and the McKinney service department did all they could to work with them, and helped us to have the claim resubmitted to insurance. After a long and painful process, we finally have our vehicle back, insurance rightfully covered the work, all because of the dedication of this team. McKinney GMC will have a customer for life in me. Thank you again team for all you did!

Excellent care by the entire Ewing team. Special thanks to Jim Bearden for getting me out of there in time for my appointment.

Great inventory selection and friendly staff. Facility was nice and they took care of me. Definitely recommend. They have great truck selection. They answered all my questions.

The teacher Silvestre was very professional and very good communication about fixed details of my car.

I had very good service from sales to signing. I would recommend this dealership for anyone looking to purchase a vehicle.

We experienced top notch customer service!! Our Sales Associate was professional, friendly and knowledgeable. We didn't feel pressured into a sale and it wasn't stressful at all.

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.

The level of care, kindness, and respect that Tyler Reynolds showed to my wife and I was unlike anything we have experienced at any dealership. Every other person of the Sewell staff was no different. I have always heard great things about Sewell dealerships and we were not disappointed. We worked with Matthew Jobe on the finance end and he was fantastic as well. Both Tyler and Matthew from start to finish provided us a true no pressure deal. I’m convinced that Sewell Buick GMC wants what’s best for my family and budget. It almost feels wrong to say that I really enjoyed the car buying experience at a dealership but it’s the truth. I want to make sure and add that the care and help did not stop when I drove off the lot. Tyler and Matthew have answered every question quickly and professionally since we have had the car. All that being said, my family will never buy from another dealership. These two men have made us Sewell customers for life.
