My new 2025 Trax had a check engine light come on shortly
My new 2025 Trax had a check engine light come on shortly after I purchased it from Robbins Chevrolet. Alex Fierro was my service mgr. from the start. He checked in with me several times a week. He was polite and concerned about my needs. I was a little frustrated because we were waiting on a part, but Alex kept me calm during the wait. He was exactly the person I needed while my car was in the service center. Thank you, Alex, and thank you, Robbins Chevrolet! Lisa O.
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

Had oil change and vehicle inspection.
Had oil change and vehicle inspection. Found some torn joints that needed immediate attention. We?re able to repair the same day. Was able to get everything completed in half a day.
Short turn radius
I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

Kaan was great to work with when I came in interested in
Kaan was great to work with when I came in interested in a Kia. He took the time to go over all the options, answered my questions, and made me feel comfortable throughout the process. His professionalism and friendly attitude really stood out. I definitely recommend asking for Kaan if you’re looking at a Kia or any vehicle at the dealership!
Great Truck
I did my research and test drove several models. The GMC 1500 Duramax does everything I want it to do and more. Great gas milage, nice power and very comfortable.

Getting a car at Autonation Katy was a breeze.
Getting a car at Autonation Katy was a breeze. Justin Hernandez actually introduced a better car for better value than the one we were originally looking at, was very knowledgeable and answered every question patiently. Great guy to work with!
Best truck I’ve bought
The features and styling are very aesthetic. The truck has very smooth handling and response. I am impressed with the response from the Diesel engine.

I had a rough first experience at Mac Haik Chevrolet’s
I had a rough first experience at Mac Haik Chevrolet’s service department, but Brian Caldwell, the Service Director, completely turned things around. He personally followed up the same day I voiced my concerns, sent a mobile tech to my house to handle the software update, and later arranged for a porter to deliver a loaner and pick up my truck for a roof recall and additional service. They performed every repair as promised—on time—including the roof fix, oil change, tire rotation, and a minor interior issue. Brian kept great communication throughout, even with our busy schedules, and treated my time and situation with real respect. What started as a frustrating experience turned into one of the best service recoveries I’ve ever seen. Huge thanks to Brian, his team, and Mr. Mac Haik. This is how a dealership should be run.
