Cornerstone Automotive - Round Rock (TX)

5 /5 Brad W.: Cornerstone Automotive are honest brokers and I am very appreciative of the way they do business. I will certainly be a return customer. Unfortunately, there was not a solution to my problem for my older truck due to the instrument cluster component being discontinued by Ford. It is abundantly clear they care about customer service and Chris is great to work with.

5 /5 Danielle L.: I had an excellent experience at Cornerstone Automotive! The team was professional, honest, and extremely knowledgeable. They diagnosed my car’s issue quickly and explained everything clearly, so I knew exactly what to expect. The repair was done efficiently, and my car is running perfectly now! What impressed me the most was their transparency and fair pricing—no hidden fees or unnecessary services. It’s hard to find a mechanic you can truly trust, but Cornerstone Automotive has definitely earned my loyalty. I highly recommend them for anyone in need of reliable auto repairs.

5 /5 Ezra McQuirter: The staff is beyond friendly and cordial, they rose above my expectations for sure. They honored a quote I had received a week prior and the mechanic team took care of my car with speed and care. I’ll definitely recommend this place to my friends and family.

5 /5 Abby Cherizard: I went to the location off of Palm Valley to fix the plastic underneath my car. I had hit a bump the other day, and my plastic cover was hanging and dragging on the road. After I explained it to them, they were able to fix it, and fast. I was ready to pay and they told me that it was a small fix and not to worry. How sweet is that!? I truly appreciate them for taking care of this little issue. I will definitely be back for any future problems! :)

5 /5 Noah Tyson: Best shop north of Austin!!! Chris, the owner is always easy to talk to and the building is pretty neat. First time I took my truck in there was for electrical problems that I was having with my headlights. I had a feeling that they were just going out because they were aftermarket LED lights, but I wanted to take it in for a second opinion and they determined that the lights were out or going out. They ended up not charging me at all, which I absolutely loved. i’ve been back twice now once for my Maintenance and second for the state emissions test and an alignment. Very professional throughout all the encounters.
