    Smog checking my wife's 2012 Toyota Camry Hybrid.
    B H.

    The owner Roger is always pleasant to deal with. It was time for my 1997 Plymouth Prowler to be tested on the Dynamometer. It trust Roger behind the wheel of the Prowler, to drive it up onto the Dynamometer and bring the car up to speed. It's definitely worth driving the extra mile to visit this smog station to experience such superior customer service.

    I've been coming here for over 10 years and have referred many of my friends and family to Roger. Fast, kind and professional. Compared to other Smog shops, this place is clean and customer friendly. Side note: there is no restroom available. Not usually an issue since you're in and out in a very timely manner. Thank you! I'll be coming back!

    Roger is always kind, quick and friendly. He was wearing a mask, had hand sanitizer and maintained 6ft of distance. There was no wait and the cost is reasonable. We always come to California Smog Test Only. Don't forget to check in for $10 off through Yelp.

    Roger is amazing. A smog check is a smog check. This place has competitive prices but it stands out in terms of customer service and how fast you can get in and out. If you value your time, just bring your car here. No fuss and you're all set for 2 more years. I've come at various times on different days and I've never spent more than 20 mins waiting. I bring all my cars here now. It's not worth going to those other smog check joints that only do it as a side hustle with some "coupon" or whatever to bring in customers for mechanic services or what not. This guy smog checks. Boom and you're out.

    See all

    Roger was really nice, and he was efficient with time (got my smog on my lunch break with time to spare).

    First time using a mobile mechanic to get out a stuck pcv valve. He got the job done. The reason…read morefor 3 stars is that while doing the job he ended up breaking one of the clips that hold the wires and didn't even tell me that it happened. Nor did he show up to fix it. Update: he did end up fixing it a couple of days later

    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 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.
