Had my car towed here and was told "car has so many codes, he didn't wanna even mess with it". Had this guy simply looked up the prior work record, that they completed, just 2 1/2 years prior, possibly could've saved me thousands of dollars and visits to different mechanics. Learned that this part that failed was causing false-positive codes. Thanks for nothing Cornerstone Auto. read more

This repair shop has a neighborhood vibe. The people all seem to care about high quality repairs and honest thoughtful estimates. This is my go-to repair shop. read more

Horrible mechanics - took my car there on Monday for my check engine light for them to tell me they cannot find anything and they reset the light. Literally the next day my car doesn't start and I take it back. Three days later the check engine light comes on again for the same code so I take it to a real mechanic and have them fix it. They told me they have had a bunch of work from fixing this places work. read more

Have used Cornerstone Auto several times for general maintenance. I feel they have been honest with the estimate and work completed as well as being sincere and trying to do a good job for their customers. McCann has always called before he said he would and on my last repair, the work came in LESS than the estimate. I would highly recommend this shop for general auto care. read more

The gentleman at the front was very kind and helpful. He fixed my splash guard in like 5 minutes and it was the best.

Harry was very attentive to my problems on my car! They found the problems and to order parts, no waiting for parts for two weeks. Parts arrived next day!! Great automobile repair shop!! Top notch with customer care!! read more

This place had a dog hanging out in the waiting room and I wish I could leave it at that because that's all I need. But really- the staff was friendly, my car was done same day and I feel like they could have ripped me off and didn't. I had my girlfriend go to get work done on her car the same week. Will return again if I have any issues. read more

AMAZING Service! We were just out of San Angelo, TX, on our way to San Antonio when the truck's A/C quit. Ugh! It was a hot, sunny, mid-September day. Driving too fast on I-10 for open windows to be comfortable for long, using the fan on full blast, and after about 30 minutes the dog in the back seat began to stink. I did a Yelp search for AC repairs in San Antonio. Several had "request quote" options; i requested quotes, knowing that they couldn't really give one based on my description of the problem, but i was hoping for a timeframe when they could get us an appt. No joy after an hour. I noticed one vendor was really close to my dad's house in San Antonio, so i gave them i call. Bless the man! He heard my predicament and squeezed us into his schedule that afternoon-- with no promises for an immediate fix... which i didn't expect since we didn't know what the problem was. We arrived, Husband drops me off with the stinky dog at my dad's, and goes on into the shop. They chatted about the issue, Husband waited while they investigated, and a solution was presented within 30 minutes. Husband agreed to the fix (a fried washer was letting freon leak) and he was back to the house 1/2 hour later. If we had been pressing onto Houston that night, we would have made it since the appt and repair were so quick! Bonus: Scout! A very charming and affectionate golden retriever will keep you happy in his service (head and belly rubs) while you wait. read more

I was vacationing FL with my car and had something called catastrophic failure where my engine just quit. I bought it at Cornerstone KIA but had it towed to a FL dealer. They told me they had to check with KIA to see what they would do under the warranty. Thy were not getting back to me, so I called Melina at Cornerstone and within 2 min she looked up my warranty and assured me it was covered, and that they should know this based on ! She offered to contact them directly if needed, or if we received different info from the other KIA dealer. She of course was correct and they fixed the vehicle under warranty. In Cornerstone's they say they are committed to their customer's Peace of Mind, and Melina did that for us and more! read more

My go to car repair place. Much lower price than the dealership and they do quality work.

The best! You won't find a more honest, friendly, knowledgeable, trustworthy automotive shop.

I have taken both of our automobiles ti Cornerstone since we relocated here about 17 months ago and we have had quality services performed on both of them. Professional and very courteous, and work done right the first time! read more

My wife was told by the dealership that she needed new rear brakes. I called Cornerstone because they are close to home, provided the info on the car, and dropped the car off the next morning. Since I live nearby, they were nice enough to give me a ride home (I work from home). I got a call about an hour or two later from the shop manager informing me that the brakes are not only good, but nowhere near needing replacement. I would have known no different had they just replaced the brakes and billed me. It's hard to find this kind of honesty these days. Needless to say, we will return here, rather than the dealership from now on. They even found the nails in one of our tires, confirmed with me that we had purchased the tires at Discount tire (three businesses down the street) and took the car there for me to get the tire repaired under the road hazard warranty. I cannot recommend them highly enough. read more

I went in for a state car inspection today. Got very quick and professional service. I am happy I chose to come here. They also have a great waiting room perk that more automobile repair shops would do well with. I've included a picture. read more

Cornerstone Automotive - Oil Change Stations Near Me - San Antonio, Texas

Amazing customer service, and auto work. Gary at the front desk is unbelievably kind and helpful. Everything was done in a timely manner, and communication was excellent. I recently moved here, so they also helped me find a good place to register my car. I left more than satisfied! read more

No issues. Service completed in a timely manner. Owner Steve and his staff were very friendly and created a very comfortable environment! Definitely will be back. Honest and sincere! read more

We've been going here for year before I even got my license. The people who work here are always very sweet and kind. They genuinely want to help and do a really good job. I've been going here for years to get inspections done and giving my car the once over with issues. They always give good professional advice and are very informative. They talk you through every issue and make sure you're heard. read more

I have been going to these guys for 2 years to do both typical repairs and so major repairs and every time I have found them honest and reliable. Two repairs they DID NOT CHARGE me for because they said the parts (spark plug and a fuel line seal) where "part fails" that should not have fail and sent them back to the manufacturer and then replace the parts with no charge of new parts OR labor. I would highly recommend these guys. I was surprised to see some negative reviews and so had a look at them and they seem to be people who had unrealistic expectations on time and prices, none complained about the quality of work. In my experience it is hard to find honest mechanics that don't over charge or up sale and these guys are honest and hard working, they get 5+ stars from me read more

If you want a place with good customer service DO NOT go here. TERRIBLE communication while I waited for 45 minutes for my battery to be replaced by a battery they didn't have in stock. A simple "this could take awhile" instead of "it should be 15 minutes" would have been much better business practice. I had to buy the more expensive battery because they had already removed he other one and I was offered NO time estimate just that we were "still waiting". I will never go back. read more

Did an excellent job replacing my alternator. Thank you! No complaints- they were efficient. I unusually do my own repairs, but his time didn't want to fool with removing the radiator to get to the alternator. read more

I've been taking my car here for service for several years--since I exhausted the extended warranty from the dealer. These guys have taken great care of my car and kept it in great shape! They are honest, hard-working, and deliver what and when they promise! They also have loaner/rental cars available to use while mine's being worked on, which is a great service! I appreciate that they keep me posted on repair progress and always talk to me before beginning anything remotely more major than an oil change! Cornerstone Automotive is AAA approved and I highly recommend them for automotive repair and service. read more

I've been taking our 02 Tahoe to Cornerstone for the past 2 years. We had it in 5 different times to fix the rear A/C, electrical issues, battery issue and for a tune-up. The owner is great and they have always delivered excellent service and work. Even when I asked about checking something out, like the brakes, they did not replace them because they were still good and they gave me the honest answer. If you need work done on your vehicle, I'd highly recommend Cornerstone Automotive. read more

I called these guys this morning and told them I needed to bring my car in because it was making a funny noise. They asked me to bring it in and as soon as I drove in, Mack came out and took a look at my car and quickly told me it sounded like a Catalytic converter and that I should take it to the dealer since that should still be under factory warranty.. Cost for his analysis: $0 The pleasure of having an honest repair shop that is not out to squeeze anything they can out of you.. PRICELESS. I will be recommending them and will be taking my car there as soon as it runs out of factory warranty. Also, the address on YELP is wrong. It is 14630 Blanco Road. Not West Blanco Road. They are located next to Whataburger on Bitters and Blanco. read more

Called ahead, needed headlight replaced before nightfall, as it is a legal requirement. Spoke with Michael. Yes, they could do it. He even gave me a few dollars off his original quote. Got oil change, headlight replaced, and inspection done. I didn't know the inspection could be done up to 90 days ahead of time!!!!! They didn't try to "convince" me to get it done, just notified me and respected my decision. Need a new air hose, but they showed me the old one, which even I could tell isn't working right. Will go back mid week for that as it was not in stock. The waiting room is not super delux, a light bulb was out, no vending machine, etc. But, it was very useable. I prefer they take their time with my car instead of jazzing up the waiting room. Both "counter" people were nice and knowedgeable. As I was in the waiting room, I heard their interactions with new customers and those picking up vehicles. I was pleased with the service on my car as well as the customer service. And, they have the sweetest German Shepard! Might be a little scary for some young kids as he's so big, but super friendly and won't hurt anyone. Great experience and looking forward to more good experiences there! **** Have been here before when it was just an oil change place about 5 years back. Not sure if this is the same place that expanded their services, or if someone bought them out, as I don't remember the original name, but this is not the same place. It's better!!!!! By a lot. So if you have had a previous bad experience at this location a while back, come on back. New people, better people, more services. I was very pleased!!!! read more

Came for a routine oil change, was told my brakes needed to be replaced soon, so I decided to check the brakes myself and they were completely fine. Tired of mechanics trying to scam people thinking they don't know anything about cars... read more

So, we have a bit of a junker (bad year Subaru, with 150,000+ miles on it). Like parts of panels have come off (on their own) and are held on with duck tape because I'm trying to wring a few more months out of the car before we buy a new one. When we moved across town I was a little concerned with finding another great repair place. Because we only have one car, it can get a little tricky to drop off/get work done without suddenly being stranded. The guys at Cornerstone Automotive are great! They have seen us four or five times in the last two months (not on them- the car had 150,000 mile part replacement time staggered out- when the brakes pads grind down you don't wait). Anyway, for one, they are really great about getting us where we need to go- either a ride home while they keep the car for the day OR (and this is the best part EVER) a $20 day rental car. Did you see that? An automotive place as their own personal $20 day rentals. I've had other automotive places drive me to a real rental car agency (with real rental car agency prices of $35-40 a day) so I was shocked and excited when I would get my brakes fixed AND go to work and not be broke! They do get busy because they are a solid, dependable, honest company. Call ahead if it isn't an emergency. If it seems like an emergency (ahem, my brakes are making the crunchy death knell of done brake pads) show up at 7 am when they open and they can usually squeeze you in. read more

Nice guys! Above board and finished the vehicle earlier than promised. We will come back if we need auto work done in the future for sure!!

Haven't used this place since 2011. When a friend asked to recommend someone Gama was the first thing that I said. He did a couple of different repairs on my car. The price was reasonable and he finished quickly on both. I haven't ever been more pleased with a mechanic before or since. Highly recommend them if you want an honest good mechanic that won't rip you off. read more

We called based off references and they took us in right away, fixing our issue at a very reasonable cost. Will definitely return for our automotive issues. read more

I have always had good service. Once when I lived on blanco, they came to my apartment and jump started my car only to turn around and come back because I turned off my car to go inside and get my purse and lock the doors. I'll never forget the extra mile taken read more

I'm an ex-mechanic with some recent physical ailments and took my car in for some minor work a couple weeks ago. Got a crazy high estimate ($900) for a simple job (common small normal wear parts replacement). Took the car elsewhere and got an 80% discount from Cornerstone's estimate. Shop around and look for recent reviews. read more

True to their motto "honest answer solid service" was told by another I needed new brake pads, took my truck into cornerstone and was told I have about 10,000 left - see you then read more

Greeted by the cutest pup in the waiting area, went for a state inspection and it took no more than 10 minutes. Once finished, they had my car waiting right outside of the front door for me, great service and a welcoming atmosphere. read more

Michael and Mac are honest, knowledgeable, and fair! I trust them with my family - they take care of our cars! read more

This place is awesome! I am fairly new to SA and I lucked out by choosing this place to fix the brakes on my Ford F350. They are honest and will only fix what needs to be fixed. They also had my truck finished when they said it would be finished! I truly recommend this place for all of your auto repair needs!!!! read more

Very disappointed when I called and left a message (as no one answered my call) regarding a 1973 ford pickup. Never received a call back, so I finally called back again and the man that answered begins to make an excuse why no one called me back and then tells me that "our boss won't allow us to work on old vehicles because we hook up our vehicles to an electronic device to help us diagnose the vehicle". What?! So the mechanics are that bad that they need a computer? That's like a cashier telling me they need a cash register to give me change or to shop there. Really disappointed. read more

Great place to go if you want honest people working on your car. I took my car in for A/C service and even though they spent time trying to find the problem they didn't charge me. The owner told me they did not have the proper equipment to handle the older freon that my car used and told me where to go next for help. read more

They completed my state inspection in 5 minutes! Definitely going back there. Thanks guys!

The most HONEST Auto Repair in town! Got a quote from them for a repair and when I went to pick it up they told me that they were able to get the part cheaper than they had thought so my bill was $150.00 less than they quoted. Tell me the last time that happened to you at an Auto Repair business. And by the way it ran great... read more

Called for an estimate on labor to install some new parts I purchased myself at an auto store but...they don't install "customer parts." I guess they would rather jack up the price on parts that they order. Or maybe their parts are super special. Oh well, thanks for nothing. read more
