TLDR: Untrustworthy to do a basic diagnostic. If you want to make multiple appointments because…read morethey are unable to diagnose and repair the first time around, then this place is for you! Took my vehicle in for a check engine light earlier this year. Already had an OBD code and suggested part replacement. They ran their own diagnostics and told me it was a different part causing the check engine light. Fast forward to today and the check engine light is back on. Got another OBD reading and part replacement suggestion and what do you know, it's the same issue and same part (for my initial visit to Cornerstone). And yes, I called and was told there was a nation wide warranty on any of their repairs. Only issue with that, is you replaced a part that didn't need to be replaced, so obviously nothing y'all did was wrong, just irrelevant to the issue I'm having. Two stars cause they are nice people; just not great at their profession.

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!

My husband originally thought it was spark plugs and changed those and did not work. My brother-in-law mentioned it could be a transmission. Dropped it off and within a day, they had diagnosed the transmission having problems. They put an additive in the transmission fluid, which stopped the vibration instead of trying to sell me a whole new transmission. They can't guarantee how long it's going to last because the transmission is actually Having issues but he said it could last 100 miles or 100,000 miles. I just appreciate their honesty and quick turnaround.

Long Automotive has been our go-to for all things automotive care since my wife and I moved to…read moreTexas eight years ago. Long and his entire team are incredibly skilled professionals in their craft. I was introduced to Long by a colleague, and since then, I've been recommending him to anyone who asks for a reliable automotive shop. Long's Automotive offers a comprehensive and honest assessment of your car. They thoroughly examine your vehicle and explain their findings, including whether any repairs are necessary immediately or in the future. They even diagnose issues that other mechanics might overlook. I highly recommend Long's Automotive. I give the shop and the entire team an A+++. I'll refer anyone I can to them without hesitation. They have reasonable rates as well.

The turnaround time was impressive. Even with insurance involved, the repairs were completed in about 3 to 4 days. Communication was solid throughout with proactive updates, clear timelines, and straightforward explanations of what was being done. The owner, Mr. Long, was easy to work with and ran a very efficient operation. The quality of the work was excellent and the process was smooth from start to finish. I would definitely recommend Longs Automotive if you need collision repair done right

MTZ had previously worked on her vehicle before. They do great work and in my own opinion they are honest than most places these days. Their mechanic talked with me in person. He told me the worse upfront, basically a new engine. The best hopeful news it was repairable, but they wouldn't know until they went through all the codes and take the engine apart. Basically at 165k+ miles the timing belt broke on the engine among other things. They also told me they recommended to replace the water pump before it went out since it was at the mileage. It a took about a couple of weeks for the entire repair. When I went to pick it up the day they said it was ready. The engine felt like new and to be honest it felt better than it did before. I am going to continue to use this shop for major mechanical needs.

I admit that it was hard to keep up with the status (it really shouldn't have taken long to replace and paint the bumper after receiving the parts or looking for additional damage). I'm giving 4 stars because they did not paint match at all. The front bumper is way too white and doesn't match the rest of the car. Cost was reasonable, though this was through insurance so it didn't matter much to me.
