I believe his name was Lozano( sorry if I got it wrong) and Anthony. They fixed my car no issues and had it up and running in no time.

No check engine light lol. The warranty they offered is just a plus!

I've waited a long time to write this review just to be sure that I actually know what I'm talking…read moreabout. My car had a check engine light for a bad sensor. I replaced it and it persisted so I bring it here. They took a look at it and let me know my car needed a valve cover replacement, new spark plugs, and to replace the sensor I had just replaced. There might have been more but this was almost a year ago so I don't exactly remember everything we did. Fine, I trust them because this place has been highly reviewed and it seemed very professional. So I spent about $1500 on repairs. Maybe a week later the same code comes on so I'm confused. I take it back to them and it takes days for them to get to the car because their "diagnostic tech" is really busy. Fine. So they call me and tell me that the code I'm getting is because my timing chain is fucked and it's going to cost $4500 to fix it... Which I don't have. So I sit on it for a few days while I see if I can come up with the money or what I'm going to do, before they threaten to charge me a storage fee for having my car with them. Fine, I understand they don't have all the space in the world. So I get to the shop pay their $150 diagnostic fee and try to take the car. The battery is dead. They gave me a jump and I drove home but there was no check engine light. I found it weird and thought it was a fluke. Long story short I replaced the battery, battery cable, oil, alternator and the car is just fine. I've been driving it for almost 8 months. I put in maybe $500 in parts. While I am trying to figure out what the problem is I message them and ask if they charged the battery, or if the battery died on them at all. No answer despite multiple messages. And this is what bothers me you have no problem messaging me multiple times to threaten me with fees but can't respond to one simple message. My point is this shop is shady. They wanted to upsell me on expensive repairs I didn't need. Now I'm not even sure if I truly needed those $1500 in repairs the first time. How do I know it was an upsell? The guy who gave me my car back said, "we just go based on what the scanner says." And that's when I knew this shop sucked. Why would I be charged a ridiculous $150 fee for you to scan my car? Personally that doesn't seem like diagnostic work (at least a proper one). I feel like some of the things I discovered on my own an experienced mechanic would have found. The car had an electrical problem. In between those two visits I took another car to them to see if they could do a transmission drain and fill. I put that in the appointment request and I made the appointment days in advance. When I get there they say they can't work on the car because it has a lot of miles on it, which again is fine but why are you making me waste my time and bring my car to you if you aren't going to work on it. Do you not have someone who checks the following days' appointments? Why does your website allow me to make the appointment if it doesn't meet your shops criteria. All in all I say stay away and find a place with honest mechanics.

I needed to replace my front and rear brakes on my 2018 Equinox. I received many different quotes…read morefrom other mechanics, quoting me over $300 for labor only. I reached out to Refined Auto with the same request, and it was a more reasonable price, especially since I had no idea if I needed to do anything to my rotors. My dad was present while Cesar worked on my car, and my dad gave me such a glowing review of how Cesar worked. My dad has not been able to stop talking about how Cesar did an amazing job on my car, how clean he works, how he keeps his tools, and his communication. My dad was so impressed with the quality of work Cesar provided on my car that he decided to get a quote for replacing his rotors. When Ceasr finished on my car, he let me know that my brake fluid was not in good condition. He drained my brake fluid and replaced it with new fluid. He explained to me in detail that brake fluid should not be topped off. I had no idea, and apparently, my dad didn't know either, and we had topped it off because it was low. Now, I know, for future reference, that when it's low, I should replace my brakes. I appreciate the work that Cesar did on my car and his communication. I will absolutely use his service again and recommend him to friends and family.

I went to FIVE different shops between February 2022 and July 2024, and each one either misdiagnosed the issue, charged me for useless repairs, or straight-up refused to work on my car because it was "out of their control." I wasted time and money, and my car ended up worse off after every visit.Then I decided to give OC Automotive and Diagnostic a shot. Honestly, I didn't have high hopes after everything I'd been through, but these guys surprised me. Gabe, the service advisor, laid everything out from the start--parts, pricing, and a solid timeline for the repairs. No BS, just straight talk. He even stayed late a few times to make sure parts were ready to go. Every promise he made, he kept. That alone put them miles ahead of the other shops. Kris, the technician, was another level. I told him everything about the car's history with other shops, and he took it all in, gave me a confident smile, and said he'd get it running. In less than a week, he had it back on the road. This guy didn't just fix my car; he cleaned up the mess left by everyone else--reconnected cut wires, reinstalled missing panels, and figured out issues nobody else could. He knew exactly what he was doing and got it done fast. Anthony, the owner, also deserves a shoutout. He broke down their whole troubleshooting process step-by-step and didn't leave me in the dark about anything. He's the type who cares about his customers and is willing to go the extra mile. He even threw in a free air freshener and a discount card, plus he gave me a discount on the overall cost. After all the headaches with other shops, that meant a lot. Bottom line---- If you're done with shops that overpromise and underdeliver, go to OC Automotive and Diagnostic. They know their stuff, they don't mess around, and they actually deliver. This is the only place I'm taking my car from now on. Highly recommend.

When I asked why it was so high, they mentioned it included some kind of "warranty" with the oil change. That didn't really make sense to me for such a standard service and felt more like an upsell than actual value. I'm all for paying a fair price for good work, but for something as routine as an oil change, I expected pricing to be at least competitive with a dealership...not significantly higher. Ended up going elsewhere.
