I recently moved to Houston and I met Roy Washington. He was very helpful and informative. Roy really cares and will do whatever he can to get you a car. Also, Moses one of the managers there was very kind and welcoming and he also worked his magic for us. Thank you GMC Group 1 for everything, I recommend buying a car from them and please ask for Roy Washington!
My first oil change at the dealership was handled very well by the service department. I arrived at my appointment time and was immediately greeted by a service manager who soon took my truck into the service area. I wandered into the sales showroom and looked at some of the new models and had a conversation with one of salesmen about Super Cruise. Shortly after returning to the service waiting room, they brought my truck over all ready to go. It had also been washed and vacuumed. it looked brand new again. I paid the salesman, picked up my key ... Read More DealerRater - Jul 27, 2026
Moses and Roy sneaky and unpredictable. Moses lacks communication and always thought he contacted me or set up scheduling. Says he will contact or call you back nope. Lies about why your car is making noise or why the light is on sends you places without a an appointment that he Moses himself said he scheduled I’ve wasted a whole tank of gas and time just from getting the run around and Roy will transfer you to Moses when you ask to speak with the GM and claim he doesn’t know the GM email. Moses will pretend to ... Read More DealerRater - Jul 23, 2026
Jordan is very accommodating, he provided us transportation while our truck is in service and updated us what else needed on the truck.
Great customer service. Jonathan was very helpful in getting me my vehicle back working properly.
GMC Group #1 is the best place I found to buy my vehicle. The service was excellent and the staff was so friendly. They kept in touch whenever I needed anything. I highly recommend this place as one of the best I visited while looking for a truck for my husband. Ask for Delwin Camacho; he was my salesperson and I highly recommend him.
I had a very pleasant experience at the Group 1 GMC dealership, specifically in the customer service area. My advisor was CeCe and she was excellent. She explained everything that would happen and kept me updated on the progress of my vehicle. I would highly recommend this dealership for their great customer service and their efficiency.
The service and Customer service wasn't that great at all. I don’t recommend at all.
The experience was top notch from the moment Delwin greeted us in the parking lot and helped us through every step of the process.
Great customer service, easy to scheduled appointments. My sales advisor kept me updated on my vehicles service.
The place is clean; quiet and comfortable. The service advisor Jasmine is very nice and professional.. Besides, I'm really enjoy the service work which is quick and efficient.. Over still the team work is great.
Excellent and prompt service. Kept me updated on service progress along with videos. My service advisor Jasmine R., was very courteous and friendly. She made a lot of suggestions of what repairs I should do urgently. She called me when the vehicle was ready and even arranged Uber to pick me up from my home
Service was quick and easy. Aaron was commutative and kept me updated throughout the day.
My advisor was very helpful cordial knowledgeable and extremely courteous. Ms. CC was a pleasure to work with
Great service employees very kind and the service very good thanks for everything you guys
Tatyana the service advisor is excellent and always does a great job ! We were in and out on the oil change and service !
The tech I use. - his name is Aaron. He is excellent. I always ask for Aaron. Good service. - good attitude.
Amazing service! Highly recommend Ronald! Very polite. Fast. Prompt. Very detailed. Gets the work done
Service manager/rep was great. Service itself was incredible horrible... Simple 1-1.5 hour oil change turned into 6 hour wait at the dealership. Not cool. It’s understandable to wait 2-3 hours but 6 hours is crazy wait time. Appointment was at 9:30. I didn’t leave til 3. Service tracker on my phone was completely useless. No one updated anything so I never knew where my truck was in service or just sitting at the lot or anything.
They say they check the tire, the tire pressure and they didn’t rear tire tires had 34 pounds instead of 35
All was ok. If they can figure out how to get basic service done in less than 2 hours, they would be the best!
My appointment was at 10am Truck was ready around noon. Good work from y'all
No communication, Hard to reach a person, had to pay for a rental while vehicle in for warranty work (they "dont have loaner vehicles") Service writer is not experienced or knowledgable about issues or how to write them up
The dealership in general is great however the service department fell short on my first visit. I had scheduled an oil change and I had a leak in another part of the vehicle so I asked to have that looked at as well. All they did was refill the reservoir without fixing the leak.
Great communication from service advisor, with reaponse in a timely manner. Service done was well explained.
My vehicle came home with scratches and dents on the back hatch and back window. I will be expecting this dealership to fix at no cost to me.
Not the best I buy a AT4X 2026 last year the dash cam installed at the dealer when buy the truck the Rear dash cam never work I bring the truck back and charge for replacement I ask for clean my truck in and out next day sxochitll don’t answer my texts or calls so I go to the dealer and ask for my truck don’t clean and try to keep the dash cams replacement it’s my second truck buy there but after this I change my business to another dealer poor customer service 😞😞😞😞
Ce Ce Marin was my service representative and she did an outstanding job informing me of issues, cost to repair and timing.
Having the Costco Auto Program here makes all the difference in the world, Gabby was very helpful in my truck purchasing process
Excellent service! Looking forward to my next purchase! Successful negotiations my last two purchases over the last 2 years
I had an excellent experience with the service department at this dealership. From start to finish, the process was smooth, professional, and efficient. My service advisor was outstanding — friendly, knowledgeable, and kept me updated every step of the way. She took the time to explain everything clearly and made sure all of my questions were answered.
The work was completed on time, and my vehicle was returned clean and running perfectly. It’s hard to find customer service like this these days, and this team truly went above and beyond. I highly recommend this dealership’s service department to anyone ... Read More DealerRater - May 26, 2026
Poor customer service in the service department. Aaron is a liar and the manager Alex is worse, didn’t take the time to hear me out to even understand my concerns. Felt rushed off the phone.
A huge thank you to Steven Mauro and Group 1 GMC Southwest for going above and beyond throughout the entire process. Their knowledge, patience, honesty, and attention to detail made everything smooth and stress-free. They answered every question, kept me informed every step of the way, and truly made me feel valued as a customer.
Exelente, wonderful great experience love how they treated me especially Aaron Fofana I come back
Debbie Robert’s was a pleasure to work with! She was professional, helpful and very helpful.
It was a pleasant experience from the service representative who helped me to get what I needed!
Service department was great. Did everything they could to work with me to make sure warranty company covered my parts. Great communication and friendly staff...minus the finance guy, but they are always kinda difficult.
Excellent online purchase with knowledge at hand with excellent home delivery in less than 1 weeks. Would definitely buy another vehicle from them. Johnathan you handled my purchase very well and everything went without a glitch
Amazing team and super efficient process! Thank you all for the exceptional service always provided.
Greet you with a smile at the service department. Always courageous, on time and professional. Listen to my concerns regarding my truck. Dealership is always
Experienced very poor customer service on recent oil change. Jordan Rasmussen refused to honor oil change promotional discount received from Group 1. Furthermore, he would not honor advertised oil change price on Group 1 website. I purchased this particular vehicle at Sterling McCall and have had it serviced there for 10 yrs and never had a single problem with customer service until Group 1 took over. I’ll be purchasing a NEW truck in a few months, but unfortunately it will be elsewhere.
The SERVICE ADVISOR Ronald Quevedo was excellent. Very patient and followed up multiple times to make sure I was taken care of. He made sure my main concern was addressed. Very helpful service center. Very friendly
Only one thing is not good, it is too long for the waiting time if you plan to wait there for the service done.
Good service good work great attention to customers need and knowledgeable of GMC product Thanks
I got in and out within 2 hours. The attendant was excellent and help me use my rewards and put my code in for my discount
While the staff is professional and friendly, the very long service wait times are out of hand. I had an appointment for an oil change and 3 hours and 30 minutes later I was finally done.
Group 1 GMC Southwest gave me the best deal on my car and had excellent customer service.
Very POOR Management ‼️Managers avoid speaking to the Customer directly about the concerns of their vehicle. Very Unprofessional ‼️Mr.Aaron the Service Advisor was very helpful and Professional.He listened to our concerns and kept us informed about our vehicle.
I felt like I was given a nice deal and treated very well. Thank you for making my purchase bery easy. Deeply apprciated.
Excellent to work with very professional and knowledgeable kept me up to date on progress
Dealership had the truck I was locking for, equipped the way I wanted, the price was agreeable and the salesperson was knowledgeable and friendly. That being said it was a great experience.
Very pleased with Eli the sales representative, unfortunately I can't say the same about senad the sales manager
Jhonathan was very knowledgeable,polite ,and helpful. He made it happen for me! Would highly recommend him to anyone looking to purchase a vehicle.
This is only dealership I feel comfortable coming too. The staff that I have encountered are genuinely caring about the customers.
The process of buying a new car was relatively easy. The sales staff that I worked with was very accommodating and helpful and made the process painless.
I'm very satisfied with job southwest GMC service does very nice workers and exelente service
I love this dealership. They’re very attentive and always make sure my needs are met.
Brought my car in for a recall and it was a nightmare! On top of the charges they drove my car 20 miles without letting me know or getting my permission! I will never go back!
Group 1 is the dealership I frequent for any service issues with my GMC Sierra. I was a bit xxxxxx to find out that Basil Khan departed the company, but then Ronald Quevedo came into my life. Ronald was great… He called me with updates when he said he would and him along with the mechanic found the problem and fixed it. I appreciate his determination, eagerness and professionalism. Honestly, because of Ronald, my wife and I will continue coming to Group 1.
The people were very friendly and helpful throughout the whole process. Gabriel the sales guy I worked with even helped explain what to look for when buying a car.
This was one of the easiest car buying experiences we've had. J our salesman was very professional and upfront. We definitely recommend checking this place out
We had a great experience! Jay provided such awesome service and really took the time to explain everything to us. The overall process was super easy and I left in my dream car - at a respectable price!
The best dealership in town. I live 20 miles away but always come to them when there’s an issue with my GMC. Ronald takes good care of me and solves all the issues.
I had a great experience purchasing my new truck at this dealership. Keith was my salesperson and helped me through the entire process. I didn’t feel pressured and felt I got a great deal.
I went to this dealership because I wanted to use gmc. My check engine light came on due to trash in my diesel. It was there for two weeks. The communication between our two parties was terrible. When you purchase a vehicle over $100k, it should not matter where the service comes from as long as it’s a gmc dealer. I am thankful that I will not have to use them again.
FYI, I was out of state when this happened or I would have used my local dealership. My dealership has apologized for Group 1’s handling of this ... Read More DealerRater - Feb 17, 2026
I have bought 2 vehicles from this dealership and have had my vehicles serviced here for years. I have never been disappointed!!!
Service was fine, Tatyana was helpful and very very nice. Car was clean when returned.
Took care of my Yukon Denal XL. They got everything fixed in a timely manner. Basel in sevice was great to work with! Thanks Basel!
Our sales rep, Eli was great. Very helpful and personable. Also good support from sales manager and finance close out
Went in with an oil leak and they said the oil leak seems to be coming from the oil sensor? No the oil pan plug was cracked which they somehow missed or they somehow broke when they changed our oil. They said we had a coolant leak but when taking to a German car specialist he told us the computer needed to be recalibrated and something is up with the sensor. We called Beck and asked what they could do for us. Nothing was done for us.
When taking our car in for oil changes they gave us a problem ... Read More DealerRater - Feb 2, 2026
Jordan displayed Outstanding customer service! He is your greatest asset. Car service could have been quicker.
The dealership was clean and smelled good. The people was very nice and courteous. I will return to get my car maintenance.
I took my car in for oil change on 1/22/26, when I used my car at night I found out that my steering wheel went up and down, left and right. And I was freaking out. Please check everything before you have the car back.
Excellent service! Gabriel Miranda was very professional and answered all my questions. Before making my purchase, I visited other dealerships, and I didn't feel as comfortable at any of them as I did here. Thank you very much!
The sales team is very friendly and supportive of my needs. I felt comfortable and not pressured to buy. I would definitely recommend this dealership to family and friends.
Always greeted with kind professionalism and great service. I’m always well taken care of when there and constantly updated on my vehicle while waiting for my service to be completed. They get me in and out in a very timely manner and I’m very impressed with their overall service.
Purchasing from Group1 was an enjoyable process. Trevor my sales rep was very professional and knowledgeable as we worked through the sales process
I have up and down with the dealership. Service is always good most of the time. My problems stem more from why I’ve had to replace a part three time in the past ten years and why the paint on my hood and roof faded and deteriorated in less than five years. But this is a systemic problem at the manufacturing.
Very friendly and caring people. Gabriel is very knowldgeable, understanding and patient. That is why I bought two SUVs from him in a month.
Personnel is friendly and attentive. I called yesterday, the customer representative was very cordial. He explained what I was to expect as per my request . After the diagnostic report , the customer representative explained the results of the report .He explained in terms that I could understand, therefore I understood what repairs need to be done to my vehicle . This was my first time at this location and certainly will not be the last . I have been to other dealerships and definitely your service does not compare. Thank you and Kudos to everyone .
Although they no longer sell Buicks, I have continued to receive good service on my Buick LaCrosse. Efficient and pleasant service reps. All in all, a satisfying experience.
This review is about our car buying experience with Mr. Keith Mack. we are beyond blessed and grateful for all of your hard work in helping us to get the car of our dreams. You are a class act; very patient, kind and a master at your craft. Your whole entire team is by far, the best in the business. You and your team made this car buying decision one of the most memorable, meaningful and important experiences we have ever had. For anyone who is interested in
buying their dream car, family car, any kind of car you will ... Read More DealerRater - Jan 8, 2026
Smooth and easy buying process. Fair pricing and I would buy from them again. Antwon was great to work with.
I’ve been coming here for over five years to service my truck, and Aaron has always made the process easy and smooth. I normally don’t write reviews, but I felt the need to leave one for Aaron and his team. This visit was a little different due to transmission work, and the technicians were very knowledgeable. They explained everything clearly and did an excellent job. My truck is running like new again. Great work all around. I’m always happy working with Aaron and his team and highly recommend them.
Great experience from start to finish. Knowledgeable and thorough on every aspect of the sales and buying experience.
Helpful, respectful, understanding willing to go above and beyond. Took the time to stay late and make sure everything was great.
Staff are friendly and competent. The facility is modern and clean. Appointment completed in a timely manner.
I recently purchased a Subaru Ascent from Group1 GMC Southwest. It was a great experience all throughout. It was a no hazle deal. Jennifer, the salesperson was professional and knowledgeable. Her manager was also great. The finance department did everything for a low monthly payment and extremely favorable warranty. Overall, I am extremely pleased with the service, product quality and finance options at Group1 GMC Southwest. I would strongly recommend to all car buyers to consider this business when on the market for a new or used car. Thank you Group1.
Had a great experience. Bought a 2024 Infiniti QX60 and worked with Doyle who was great to work with and made the whole car buying process seamless. Highly recommend this dealership and especially Doyle.
Fast and great experience front beginning to end! Mrs. Debbie was great along with management and finance.
GREAT SERVICE, QUICK IN N OUT..VERY NICE N FRIENDLY HELP...XOCHITL WAS VERY HELPFUL Y VERY FRIENDLY...THANKS FOR ALL YOUR HELP..
Recently bought used Ford Explorer from GMC southwest; could not have had a more pleasant experience buying a car ever! Debi Roberts was more than helpful in getting repairs done after we bought the car. I would not hesitate buying from this dealership again!
Found a GMC Yukon on the website , I just needed the bottom dollar price off msrp. After about 3 hours a manager told me they do not and will not come off MSRP. It was a waste of time and energy. I could have been calling another dealership instead of being told I will get an answer shortly. Very frustrating, they need to tell customers they do not come off msrp upfront.
Great experience having my vehicle serviced. My Service Advisor took time to listen to my concerns and addressed them in detail with knowledge and professionalism.
Charged me almost 300 dollar to replace lightbulbs and even then didn't fix my issue.
My service advisor was excellent, personal, professional and he made you feel very comfortable. He took excellent care of my car.
