I can't express how grateful I am for Performance Auto Repair in Costa Mesa. Even though I live all…read morethe way in Chino, something about their reviews made me feel like I could trust them -- and I was right. When my SUV overheated and the engine failed, I was overwhelmed. But the moment I spoke with them, it felt like a weight lifted. They understood exactly what was happening before they even saw the car. Instead of pushing a costly $6,000 engine replacement, Byron found a way to rebuild the engine through a machine shop, saving me thousands. That kind of honesty is rare. The repairs took time, but they never rushed. They kept us updated, checked every detail, and refused to release the vehicle until they were absolutely sure there were no leaks, no issues, no surprises. After dealing with another shop that returned our Honda Pilot with oil leaks, this level of care meant everything. What stood out most was their integrity. Their kindness. Their commitment to doing the right thing even when it takes longer or costs them more effort. If we lived closer to Costa Mesa, we'd bring every one of our vehicles here without hesitation. There truly aren't enough words to describe how thankful I am for Byron and his team. They didn't just fix my SUV -- they restored my trust in what an honest auto shop can be.

I used to go to mechanics in Santa Ana but was not always able to get the services I needed. Now with a new car, I was tired of getting price gouged for a simple oil change at the dealership. At Harbor Auto Service, Mike and John get the job done at an affordable price and take customer service to the next level. For example, when you have already paid and are all set, they park the car right outside for you and send you on your way. They are respectful and take the time to explain what is wrong with the car and give you plenty of options. They also have a nice waiting room with a tv, couches, and offer water as you wait. I have been here twice, and each time has been pleasant. I am already recommending them to all of my friends and family as a solid, trusted choice!

Gary, the manager, personally added oil and had a lovely young man who was, of course, sweating, added air to my tires. This is the great service this location of Expertec provides. Normally, it's preferable to make an appointment and Mike will drive you home or to the office AND pick you up when your car is ready. I have never had such good service anywhere! Of course, I highly recommend Expertec Costa Mesa!

I was going somewhere else prior and they would keep my car the entire day for a basic oil change. The first time I came after having my car serviced elsewhere and heard an odd sound when I got it back. I asked ExperTec if they could get my car back to me by the end of the day and they weren't sure, however I did get my car back within a few hours. I think they're priced fairly compared to other places in the area. I like that they're open on weekends too. I'm not a mechanic by any means but I'm also super wary of being taken advantage of which happens almost every where I go. I will say they did tell me my car passed their inspection then tried to recommend a bunch of services I'd had done recently. They didn't push me to get them or try to scare me into thinking my car was going to explode if I didn't do the recommended services lol. I've recommended this place to a couple people and they've been happy too so I think they're pretty good overall.

Communication was solid, absolute pleasure to work with. I highly recommend having a PPI service done on a car that you seriously intend to buy.

My muffler, pipe, and catalic converter was jacked up. He helped me fixed the pipe and muffler the best he can and he notified me that there was still a warranty on my vehicle so he didn't touch it and he gave me fair pricing. When I took my car to Chevy, they were so unprofessional and dumb. I had James explain what's going on with my vehicle and how Chevy had to honor my warranty, but Chevy Costa Mesa were being lazy. They didn't even look at the vehicle but diagnosed it just by hearing it. I brought my vehicle back to James and he took pictures and referred me to HB Chevy and he didn't charge me. James and his shop are truly about the people and getting their vehicle fixed. His shop and customer service is something every auto shop should emulate. I will always go to this shop for my auto needs. Chevy Costa Mesa can get bent. Thank you again James for you and your crew.

I previously left a five-star review because I had a good experience here. At the time, EU was…read morehonest enough to tell me I didn't need a tire rotation, which saved me money as a student. Because of that, I came back for multiple oil changes. Unfortunately, my most recent visit was completely different. I was charged a high price for what should have been a simple oil change and cabin/air filter replacement, and I ended up waiting about two hours for the work to be completed. After talking it through with someone more familiar with car maintenance, it became clear that I was likely overcharged for a job that should have been quicker and more reasonably priced. What made the experience worse was the interaction before my appointment. When I asked for clarification about being told I may need "air," EU laughed at me for asking. I'm neurodivergent and sometimes take things more literally, so I was just trying to confirm whether I was being charged for something that is often free. Instead of explaining, I felt mocked for asking a simple question. Because of this experience, I no longer feel comfortable or confident returning here. I'm sharing this as a caution for other customers--especially women and neurodivergent people--who may not be as familiar with car maintenance and rely on mechanics to be honest, respectful, and transparent.

I'm not mechanically skilled, so it was good to see how they checked for puncturing. And by extension, showing that work is being done. Some other shops will say they did services but just cold pitch it to upsell. I appreciate the team for helping me get on my way. Because they are dedicated to helping people, I'd definitely recommend them. Thank you again.

He always charged me a fair price which is why I respect him a lot. I've never had a BS service recommended by him. Everything is "hey, look at this" or "this is what is wrong".
