Welcome to Chuck Nash Buick GMC

I had some service work done after my AC died on me in our Texas heat, and delt with Megan who was absolutely AMAZING in service, from start to finish. I can't tell you the frustration I had when I purchased my extended warranty from Bluebonnet, and had to call the war company only to hear nothing but negatives from them. I took my vehicle to Megan at Chuck Nash, and explained the situation, and she said "I got you!" and I believed her. She kept in contact with me 100%, and let me know everything they were doing, and what they were waiting on. She NEVER over promised anything, and was straight out of the gate. can't say enough about the service, and professionalism from Megan, and everyone I ran into in that dealership, and service dept. I'm not one to write reviews much, and just let things go because of all of the intitled Karen and Bob's of the world who except everything for nothing. I'm not that guy. I genuinely appreciate her, and the service department she represents. Art Garcia

Don't waste your time, they never get back with you when it comes to getting an update on the vehicle you're purchasing. Called them for a whole week and they kept saying they'll call back. Told me they loaned out the car I was purchasing and kept saying they'll try to get it there and never did.

I had a great experience at Chuck Nash Chevrolet's service center in San Marcos. The lounge was comfortable, and notifications on the TV screen let you know where your vehicle is in the maintenance queue. Staff were friendly and helpful, particularly Riley Borneman and Ivan Gallardo. Highly recommended 👌

Excellent Service

Thank you, Alex Perez, for helping me get my 2025 Equinox! From the very beginning to the very end, Alex made the whole process smooth, easy, and stress-free. He was professional, helpful, and really took the time to make sure everything went well. I truly appreciate all of his hard work and would definitely recommend Alex Perez to anyone looking to buy a vehicle. Thanks again, Alex!

I’m incredibly thankful for the experience I had with Jay at Chuck Nash in San Marcos, TX. He was kind, patient, and truly took the time to make sure I felt comfortable and supported throughout the entire process. Jay listened, answered every question, and made what can be a stressful experience feel easy and positive. You can tell he genuinely cares about helping people, and that made all the difference. I highly recommend Jay to anyone looking for a great car-buying experience.

5 stars specifically for Salesman - Daniel S. So helpful and insightful. I could not be more happy with my experience.

Its hard to find great employees willing to go the extra mile and provide excellent customer service. Keno understood my concerns and addressed them immediately. He is a very professional and respectable. Rather than spoon feeding you a bowl of malarky, he did right by asking the questions and providing correct answers while responding with empathy. Previous experiences had me reconsider stepping foot back onto the service lot. The five stars are for Keno and as of today, I will only work with him.

Two Months of Finance and Paperwork Failure – Deal Still Not Fixed On September 22, 2025, I purchased a used 2025 GMC Sierra with ~17,000 miles from Chuck Nash Chevrolet Buick GMC. I traded in two vehicles: -2022 GMC Sierra – financed with GM Financial -2022 Buick Encore – financed with Chase Auto Finance The next day, September 23, I discovered the odometer mileage on the 2025 Sierra did NOT match the contract. The truck actually had nearly 24,000 miles—almost a 7,000-mile discrepancy. I notified the dealership immediately. On September 27, I met with the used car sales manager. He refused to offer anything in writing and verbally offered only free fuel and oil changes for 7k miles. When I asked for that in writing, he told me: -“I won’t be held hostage over the mileage error.” -“Take the verbal deal or we’ll cancel the deal.” I asked for until the next day to decide. On September 28, I cancelled the deal and returned the 2025 Sierra. The dealership returned both of my trade-in vehicles. That should have been the end of it. It wasn’t. As of November 14, 2025 — almost TWO MONTHS later: 1️⃣ 2022 GMC Sierra loan (GM Financial) — STILL not reinstated GM Financial shows: -$0 balance -“Payments Unavailable” They repeatedly tell me they are still waiting on Chuck Nash to submit the unwind paperwork. 2️⃣ 2025 GMC Sierra loan (Greater Texas Credit Union) — STILL ACTIVE & LATE Even though I returned the truck on September 28, the credit union shows: -Active loan -Payment due Nov 6, 2025 -Loan now marked late I am being charged for a truck I do not have. 3️⃣ 2022 Buick Encore loan — delayed so long, it showed months of late charges I finally sold the Buick myself to Mercedes-Benz of Austin, but that transaction is still not fully completed, and I am still waiting on final resolution. Loyal customer for 20+ years — treated like this? I’ve bought over 10 vehicles from Chuck Nash in the last two decades. This is only the second issue I’ve ever had with them — but it is by far the worst. I truly don’t believe the dealership appreciates long-term loyal customers. If this is how Chuck Nash treats loyal customers, then it may be time for me to go elsewhere. Shame on you, Chuck Nash. Shame on you. Buyers beware.

Great customer service.

5 stars specifically for service writer Sam K. Very helpful, responsive and easy to get in touch with.

Fast and friendly service. Had an oil change, tire rotation and car wash in one hour. The oil change is a little expensive but had a coupon that the dealership provides so I was happy with my service.

When I went into the showroom I honestly did not know what I wanted but Jesse Garcia Arellano immediately came up to me and asked if I needed assistance. He had no idea how picky I was when he asked that question. I told him all the things I didn’t want. The only things I definitely wanted were a medium size SUV with a large cargo area and leather seats. I currently owned a GMC Terrain and I was happy that. Jesse was so patient with me and my demands(pickiness). He drove me around the lot several times and searched his computer for the perfect vehicle for me. Finally after several hours Jesse found my perfect vehicle! It is a 2025 Buick Envision in Smokey Amethyst with light leather seats. I’m loving my purchase and I am eternally grateful to Jesse and his patience. He helped me setup and understand the space age dashboard and made sure I was comfortable with everything before I left for my travel home, which by the way is 40 miles from Chuck Nash. This is the fifth vehicle I’ve purchased from them because of their excellent customer service. if anyone is considering purchasing a vehicle, go see Jesse at Chuck Nash!

We were in search of a vehicle and found David Garcia @ Chuck Nash. Who is kind responsive & very courteous. We were very satisfied with his service. He was very helpful in purchasing our vehicle. I recommend him & Chuck Nash very highly! Thanks David be showered with God’s Blessings!
