My car literally broke down almost in front of Cornerstone. I had been in once prior for a new battery. I shimmied in, ran inside ( it was close to closing time) and was assured they would look at it first thing next day. I got a call at 7am telling me a solenoid was going bad, quoted what I felt was a fair price, and called again at 11:20am to tell me it was ready! Car currently running like a champ, and I am extremely happy with the service I got at Cornetstone! I will be back! read more

Honest and trust worthy. Dropped my SUV off for routine maintenance and they notified me of a challenge from a prior different auto shop repair. Recommended to have them re-fix it while still under warranty. Great service with fair prices. Highly recommend. read more

Great location for your vehicle service and repair. Fair pricing and great warranty. I would recommend this business.

The guys here are so nice and helpful I never have to wait when I have an appointment read more

First of all, there's nothing like reminders before your appointment at the end of a long week via text. Headed out of town and need to get my oil changed sooner than my dealership was able to do it so I came to their partner. I'm so glad they partner with them and are open to additional education and services of what I need for my car.thank you for making this smooth easy for me. As a woman, I don't know a lot about cars, but I am continuously learning and I appreciate the education that comes from people who are willing to share. There's nothing like buying a car and not knowing exactly what to do with it or what is wrong with it. No one I just got a simple oil change, but an oil change that will last me a longer time than the typical which is synthetic oil was key to the success of my previous car. I had it for almost 9 years before I had to trade it. The value of the pricing is pretty much standard in the community so I did not have a problem paying the fees along with the additional filter that I needed for my car. Lastly, there's nothing like great service. Thank you, gentlemen, for all the kindness that you provided to me, the clean lobby, the great coffee, and the wonderful books that you had in the lab lobby to read. No complaints and a happy customer read more

Cornerstone Automotive - They even have free coffee and they bring your car to the front like you're a valet customer which I guess I am - Auto Repair Near Me - Round Rock, Texas

See all

AC work. +Got it back. Yes it is good and cold. +Same day service done. +/- free oil change next service - Makes hising and hollow sounds now.(sure they will try to sell me a compressor other other $$ AC part they they didn't identify as a issue at time of diagnosis) - Cracked the Radio surround.(needs replacing now) -For work done, I felt the bill was a bit over priced. This was my first and last time with this company. I did not call back to complain about cracked dash part($200) Or about the noises( don'thave time or the hassles to hear excuses). Both things SHOULD have been caught at time employee broke trim and that still hissing during AC check for working or not. That makes me feel that there is no Quality Assurance Checks and they Don't "man up" at the time when they knowing, accidently break/crack customers vehicle. Lots of "hope cust. don't discover" going on. NOT COOL! Makes this customer feel that these things were done with the purpose of having you continue to re-bring in you vehicle for work, rework, or something out of the blue that is wrong now, to keep the $ flowing there. Maybe they are good at other services, like inspection, oil change, tail light bulbs I think I will continue my hunt for a reliable automotive repair. read more

I used Cornerstone back in 2022, not too long after they had opened to replace the brakes on my classic car. They did a fine job and I was very happy with the price and experience. Fast forward now, and because of how pleased I was with the job they did, I called to see about them doing another job for me on my modern vehicle--something very straight forward--replacing the front shocks. I now live about an hour and twenty minutes away, so I called to get a ball park quote on the cost. Nope, they no longer do quotes over the phone and want me to drive roughly 3 hours round trip just for a quote. So much for trying to be a loyal customer. read more

Extremely professional and courteous service. They always greet you with a friendly smile and offer the best advice/plan for your particular vehicle requirements. I would recommend them as I do regularly to everyone! Honesty and professionalism is the mark that should be on the door as you walk into their business operation. Very cost friendly and followup after the work is always requested by the manager as well as his staff. Keep doing what you do and prosper to we're you can open a second shop in east Hutto! read more

The measure of an automotive repair shop isn't always found in the work they do, but in the honesty that comes otherwise. My car is an import that broke down directly in front of Cornerstone Automotive in Round Rock, managed by Chris Heimann. To his credit, the mechanics gave a great assessment of what was wrong with the car and advised me about the best places to take the car to. The honesty and knowledge is well appreciated! read more

Great service. Honest and trustworthy. Had my car fixed for much less than the dealership and got it back same day. Thank you Cornerstone Automotive read more

I was there when they opened and I've spent thousands. One blistering disappointment follows the next. Unqualified mechanic ruins a months-old, $600 radiator, and they point it out like, "Oh, we noticed this." I call the manufacture, "Yeah that doesn't just happen." Plugs and wires replaced, and one wire is so long it smacks the fan like a machine gun. I picked it up on a Sunday, so I had to pop the hood and zip-tie a FEW of them. Later, I bring it up at the counter, "I am so sorry, but we let him go. He does not work here anymore. Yeah, not a good hire." Awesome answer - we're responsible but not accountable. Heater core replacement, and spilled coolant seeps into the cylinders. "It's not throwing codes, so we don't know what's going on." Also, ruined the dash and the speedometer cluster while they replaced the heater core, and lost parts while leaving the broken pieces on the floor and seats. Delightful. I had to take it to three mechanic shops until an engine specialist figured it out. So, yeah, my feelings about these experiences are not good. read more

Great Automotive Shop! First, the owner is super friendly, great communication and they answer their phone quickly and reply promptly. Second, after their inspection of the problem, they text you a report clearly showing any problems or concerns with your car and the cost of each. From their final estimate, you can approve or disapprove any work to be done. Work begins immediately after your approval and my car was repaired and ready to go when promised at the exact cost estimated. Highly recommend! read more

This place is honest, friendly, and reasonable. They dont pressure you to have work done, Im always in and out quick and they are always polite and dont bug me to have unnecessary work done. read more

Great service and quick turnaround for my sisters car when it was some issues. Fair pricing . Will use again!

I have been bringing my two vehicles to Chris, Travis and their crew for about 18 months now and they have been nothing but absolute professionals. Honest prices, better service than the original Toyota dealership I was bringing my 2018 4Runner to. They have been a few hiccups but they own up to it and make it right, every time. You will be pleased with their work and professionalism. read more

I have been having issues with my car not starting/stalling every time I gas up since September. I had taken it to a different mechanic shop, but they never could experience my car acting up. Robert and his team kept trying, and finally saw what I had been experiencing. Quick diagnosis and repair after that. Kept me in the loop and never talked down to me. Recommending this shop to everyone I work with. Fantastic work guys!!!! Sincerely, Kia Rio owner read more

Brought a tire to this little shop of horrors to have a plug put in.....the guy told me to cone back at 2PM (2 hours). When I returned,I was told that they couldn't fix it because the tire was to old.....I noticed the next morning that the tire was returned ti me on the wrong rim...mine is a 5 lug for hubcaps and I was given a 6 lug RIM.....I returned the next day ti get this resolved, and immediately the guy at the desk denied everything and nade countet accusations.....He didn't offer to go and check the shop nor was he the least bit helpful. I PREFER POSITIVE REVIEWS, BUT EVERY NOW AND THEN, YOU CONE ACROSS TRASH BUSINESSES THAT PEOPLE NEED TO BE WARNED ABOUT!!!!!! THIS LITTLE SHOP OF HORRORS IS ONE OF THE ONE'S THAT YOU SHOULD STAY FAR,FAR AWAY FROM!!!!!!!!!AMATEUR HOUR!!!!!!!!!!!!!!!!!! read more

My a/c blower was going out. They checked it, ordered the part and put it back together so I wouldn't be carless that day. Brought it back the next morning when the part arrived. The owner gave me a courtesy ride home. Truck was ready three hours later. Owner picked me up and the repair cost was half of what I thought it would be. Excellent job and now I have my new mechanic. Thanks Cornerstone! read more

Outstanding service, every time. I will bring all my family cars here from now on. Support local!

I've been taking my Jeep Wrangler JKU to Cornerstone Automotive for the past two (2) years and I have been incredibly impressed by how well run this shop is every time I'm there. Recently, I needed a new set of tires. Chris Heimann and team took care of my vehicle and made sure I had the perfect tires for my Jeep. The new tires look great! I'll definitely keep coming back... read more

I thought this place was honest but I was wrong. Shortly after my oil change there was coolant leaking into my oil, which by the way, when they changed my oil it got back to me it was overfill which may have contributed to my head gasket leaking. I cleaned out my carb and combustion chamber because I have a GDI and it is possible that some carbon deposits were actually sealing my head gasket... but it is kinda interesting that I started having issues RIGHT AFTER I had my oil changed at this place. I don't make a lot of money and this place did me over. Hopefully they get more than what they deserve later in life. So I spoke to them on the phone as well. I had a overfilled oil level, dipstick had coolant, coolant levels dropped quite aggressively. He told me he doesn't believe a overfilled oil would do anything but I told him that judging from my experience AND the experience of other mechanics I know online self-help videos, etc... that an overfilled oil can cause problems even if it is slightly over filled. My engine isn't huge... and I know dirty oil can cause the same problem too that was the other thing when I completed my oil change my oil got dirty, very dirty, in less than a month's time! read more

Just moved to the area, and state, so I had to get my cars inspected. Went to Cornerstone, on consecutive days for my two cars. The guys were very courteous and professional, even put air in the tires of my Camry, as the low tire pressure light was on. I will not hesitate to give Cornerstone more of my automotive business. read more

New shop in the area. Top notch service from Chris and and his team. I had an alignment done, in and out in less than 30 minutes. After service I was provided a print out of before and after to show what was corrected read more

After getting a huge repair quote from another shop I decided to take my wife's car to Cornerstone for a second opinion. Although the first shop's diagnostics were correct, Cornerstone's quote was $1000 less. This is a great place with good people. I'm bringing all my family's vehicles here from now on. read more

Just swung by this place randomly after finding out I had a tail light out. They popped in a new one for me at no charge within ten minutes. Now that's good service. Will be bringing my car here in the future for sure, very nice staff. read more
