Customer Testimonials
Tatyana is the best advisor. This is her second time assisting me with my vehicle service maintenance and she is so patient and knowledgeable. She explains recommendations and why they are recommended. She always works with my hectic schedule. I am so grateful. I stumbled upon this dealership after the one I purchased my car through did not have service appointments available that fit my schedule and after my first visit with Ms. Tatyana she has a loyal customer for life. Thank you group 1.
Took my 2021 Buick for an oil chang. Arron always does an amazing customer service.
Worst service ever. I spent $1,300 for an oil leak and check engine light. A few days after the repair was completed, my oil continued to leak and my check engine light returned. Spoke to my repair rep, and she advised me to trade my truck in for a newer vehicle. This is unacceptable. I brought my truck to the dealership because I thought you guys knew what you were doing. Should have went to a mom and pop shop instead. Very disappointed with Group1 GMC.
I had a great experience with the dealership. The entire process was nice, easy, and stress-free. Everyone was very helpful, friendly, and made sure everything went smoothly. I really appreciate the great customer service and would definitely recommend them to anyone looking for a new vehicle.
I had a very pleasant experience, everyone was nice and I got what I wanted at a price I could afford
Well the 2 and a half hour wait was nice and no one texted me this time to say if I needed extra services or that my car was ready and the bay lost one of my caps for my tires and no one cared or give me one replacement, my guy that took care of me from when I came left early and did not say I’ll leave someone else to help . Good thing is I got a discount on my oil change
Jasmine was an amazing person to work with my technician was great. Dealership rules to warranty isn’t fair I believe me having pay fee for part my extended warranty would cover and charge me for it is very unprofessional on group one end I feel like 125 fee should never had come from my pocket other than that my experience overall wasn’t bad
I enjoyed my visits to gmc group one. Jasmine always makes my visits easy and helps with making this process easy give her a raise.
The customer service from our salesman Quincy was above and beyond he really went the mile in making our transaction amazing
Jasmine, service writer was very professional and knowledgeable about the service that I needed today. I was very pleased! She is a valued asset to the service department!
Excelente muy amables 100 recomendado todo bien muy contento con el servicio siempre que voy
Great service from Roy he went out of his way to get the deal done on my new RHO really fast and swift
I went in today for an oil change and replace one tire. Went in at 2:00 with an appointment and left a 5:00 and they left off one of my hubcaps for a 100,000 dollar truck. I have to go back tomorrow and try to fix this issue. I had a problem last time I can in for an oil change. Not sure why this is so difficult.
UPDATE. It got worst. They are completely incompetent. Yes they replaced the hubcap. I went and checked the spare tire that they replaced. It was loose under the truck and the safety cable was not ... Read More

Fast efficient service. Not hard sell on extras. I am very competitive taking my SUV there
Fast reliable service. They even gave me back my car washed as an extra. Staff very friendly and professional
I brought my vehicle in September 5 to get the oil changed and I picked it up that same day and drove it back out of town to Beaumont Texas and I have noticed my brakes were feeling spongy. I really didn’t pay much attention to it because the vehicle was stopping OK but a week later I go to feel my washer fluid reservoir with fluid and noticed the brake reservoir cap was off. This is unacceptable. I am now wondering if I have air in my lines due to them not putting my break fluid reservoir cap back ... Read More

Very good and very fast and very polite, I've been dealing with them for a long time, I'm not going anywhere, and Service Advisor ,Jasmine Robinson is very very polite and nice, keep up the good work lady
Cece is wonderful to help me out! I appreciate her professional service and patience with me.
My service technician Jonathan Marin is great. Very nice, helpful and caring. His manager Shane is horrible. The dealership CANCELED my warranty for no reason, not only once but twice now! It took Shane over a week to figure this out and in the mean time I had a $2300+ rental car payment. The dealership paid $300. Toward this and the warranty paid $300.. I felt ripped off because of their incompetence. You would expect better treatment.
Aaron is always very pleasant and explains the additional services that suggested for my vehicle.
My service tech was very helpful and courteous. From driving in to leaving everyone was on point
Great sales process; Finance people were nice. Bought a Truck a couple months ago and have a warranty issue that I need help with. Manager won't call back, which is very disappointing. I was hoping that they would be as helpful after the sale but that's not the case. Oh well, That's the Big Box Company experience where you're just a number.
Great service, service advisor jasmine was very professional at her job i give her a 10 rating thank you all.
My service advisor Cece was the best. She really take care of people and care. Cece did everything to make sure that my truck was fixed right.
Scammed me on a warranty; the salesman told me I had a much longer warranty than I did. I spoke to the manager, Moses Ramirez, and he told me that I was wronged and offered to sell me another warranty. Scamming pieces of xxxx who will screw you over and try to charge you more. I contacted them over 5 times by email, 3 times on their website, and called over 12 times. His employees will lie for him; his secretary will not allow you to speak directly to him and will lie for him all hours of the day. I had to ... Read More

I took my SUV in for service more then $8k; they took a week, even though I had been told it would take three days. I have to cancel mi appointment in Mexico, Less than two days later, the new shock absorber they installed blew out. I had the truck towed back from Mexico, and it’s been there for a week now with no progress.
When it comes to customer service, Mr. Aaron is excellent. Friendly, accommodating, and very helpful, he will ensure that the task is completed to the highest standard.
Always give me great service and upmost loyalty with satisfaction guarantee to please the customer
Harry was clear and precise on my repairs, communication was excellent always have a great service experience
I had a Great experience! Jonathan is always very helpful and quick to response, even afterwards
Eran took great care of my vehicle and showed great customer service. The mechanics there are truly some of the best in Texas. My car needed a lot of work but now it is running like new. Thank you Eran and thank you to all the mechanics that worked on my Lacrosse .
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

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

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

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
