I can't express how grateful I am for Performance Auto Repair in Costa Mesa. Even though I live all the 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. read more

Very pleased with the work and service that I received from Byron and his son, Josh. They are honest, transparent, and charge seemingly fair prices for parts/labor. I feel like I have finally found a good shop! read more

Had to do lots of work -- but these guys again treated me in a fair and honest manner. My repairs were costly (I have a 2014 so I knew it was time), but they fully explained everything, saved the parts, and did the work quickly and right. Again. This is my place. read more

I recently moved to Costa Mesa, and when I discovered power steering fluid all over the ground, I needed to find a mechanic quickly. With plenty of shops nearby, I went through the reviews and Performance Auto immediately stood out. People consistently mentioned their honesty, expertise, and customer service, and my experience lived up to those reviews. They were able to diagnose and repair the issue within a few hours, kept me informed throughout the process, and clearly explained what was happening. Since several different things could have caused the leak, I appreciated how thoroughly they evaluated it and accurately identified the problem. Luckily, it turned out to be a relatively minor repair. Everyone was friendly, knowledgeable, and genuinely helpful during a stressful situation. The repair also cost much less than I anticipated, which was a welcome surprise. It's great to already have a local mechanic I can trust, and I'll definitely be returning to Performance Auto for any future automotive needs. read more

Byron and his staff are top tier. Their diagnostics and honest answers are what put them above other shops. I had my car misdiagnosed at another place twice and repaired things that probably didn't need to be, but Byron and his staff took their time and explained what they did to diagnose, and recommended what they believed the problem to be and they were right. Their pricing is fair and the whole staff is very friendly and they treat you with respect. read more

I always appreciate finding a thorough and reliable review when it comes to car repair shops, so I wanted to share my own experience. I have a bit of a "problem child" in the form of my Mercedes AMG, and recently the radiator started acting up. I took it back to the shop where I last had it serviced, and I have to say they were absolutely dependable. Josh and Byron were incredibly helpful, honest, and most importantly, really skilled at what they do. They were efficient, kept me in the loop, and made sure everything was crystal clear. If you have any car (European, American, Japanese etc. they do it all) with issues or just need regular maintenance, I highly recommend bringing it here. Oh and if you're planning to wait for your car while they work on it, I highly recommend walking over to Moon Goat just a couple mins away. read more

This place was quick, reliable and trustworthy. Finding a place where you can get genuine advice on cars is tough. However, from the moment I stepped in to drop my truck off for overheating, I felt relief. I have a Chevy Colorado and I brought it in on a Friday around noon. They were a bit busy and let me know I would get a phone call letting me know what the issue was and that then it would be ready on Saturday. That was exactly what happened. They were determined to see what was going on and tested my car extensively. I was very satisfied and will come back again in the future. read more

Performance Auto Service & Repair - Auto Repair Near Me - Costa Mesa, California

An honest expert mechanic that I'm so grateful to have found. Byron has been keeping my cars running for years. I highly recommend him but low-key I want to gate keep this place. I don't want the spot to be blown up, but hey, when you work so hard, you deserve to gain a loyal and strong following. read more

Amazing experience! These people are incredibly trustworthy and honest. They took the time to explain everything to me without any pressure. It's hard to find an auto shop you can trust! I highly recommend them and will definitely be coming back for any of my car needs!! read more

Byron is the best. He is so kind and has the best attitude, uplifting and positive. It's so evident that he cares about his customers and is always looking out for them. read more

Excellent experience from start to finish! Byron and Josh were friendly, communicative, and took great care of our car. They kept us informed throughout the process, and their customer service was outstanding. I highly recommend them and will definitely be back for any future automotive needs. read more

First off, we have to thank Connell Chevrolet. If it was not for their buffoonery, we would have probably not come across Byron and his team at Performance. Chevy Suburban had some issues. Took it into the dealership. They checked it out and as per usual provided us with a healthy menu of "needs immediate attention" a la carte items; the most pressing of which was a leaking radiator. The total price was somewhere North of $6K....$6....K. Enough is enough. Especially seeing as how we just sank a wad of cash for a new transmission in July. Yelp, tell me who we should go see. Performance my child. Made the call. Talked to Byron and gave him the situation. He was very straightforward, honest, personable. You talk to Byron for the first time and you feel you've known him for years. Bottom line - Byron and his Performance team fixed our issues at a fraction of the cost provided by the dealership. I have always been fully aware that going the dealership route is ALWAYS the pricier path - but, Byron was waaaay under and cooler to work with. Plus, the efficiency was top notch. Problems identified, parts ordered, work completed in about 48 hours....Connell had our car for about three weeks for a previous repair. Finding a reliable, honest, personable and competent mechanic is worth its weight in gold. I would absolutely recommend Performance to anyone needing work. read more

It's hard to find good, honest mechanics in today's world...where sometimes greed can overtake decent pricing, and throughput supersedes quality of work. That's not the case here with Byron and Performance Auto Service. First off, Both Byron and Josh are some of the most down to earth, nice, and welcoming people. Honesty and integrity go a long way, and these gentlemen have it in stride. I only just met them, and I feel like I could post up shop and talk all day with them. But onto the actual story: I brought my 1988 Nissan pathfinder here because it wouldn't start. I normally would attack this myself, but after looking at the Haynes Repair Manual, and YouTube Videos... this was not the job I could do in my carport. I called Byron, and he gave me the run down. I towed my car there, and everything was completed in the time table that I felt was fair for their workload. Not to mention at a price that could not be beat. They also kept me posted with pictures/videos of some of the work they were completing. Byron told me that if anything goes wrong, to just let him know. There's a reason this place currently sits at 5 stars, and that's because they define what a good local mechanic should be. Do not hesitate to give them a call to help you with your automobile needs. I promise you, you will not be disappointed. read more

Performance Auto is my go to spot. Honest and reliable business, hard to find! Byron and his team have excellent customer service and communication. They also have very fair prices! Give them a call and they'll take care of you :) read more

Byron is an amazing mechanic with the most fair prices he's fixing something on my car for $100 in Beach Auto quoted me $2,600 just an example of how fair he is. My car is a Audi A4 2013. I went in because of a check engine light. I literally stopped by and he saw me immediately and lifted my hood and knew exactly what was wrong and saved me $2,500 It's just great that I have a mechanic that I completely trust based on the way I've been treated in the past by him. read more

Honest, Reliable, and Exceptional Service! My boyfriend and I have been taking our cars to Performance Auto Service & Repair ever since we moved to Southern California four years ago, and Byron has been there for us every step of the way. Recently, I knew something was wrong with my car when it started sounding louder than ever. Byron took it for a spin and immediately knew what the issue was. I left my car with him for the day and he sent me a video of my car come here do problem had it fixed in just a day, and now it's back to running quietly and smoothly like normal! Byron is not only knowledgeable but also incredibly honest and patient. He takes the time to explain everything thoroughly, and always ensures our cars are in top shape. We truly appreciate his professionalism, attention to detail, and the level of care he puts into his work. If you're looking for a reliable auto shop, this is the place to go. Highly recommend! read more

Highly recommend the team at Performance Auto--they've earned my complete trust. When I brought my car in, they carefully reviewed the entire list of recommended repairs from the dealership. After their honest assessment, I ended up paying a third of what I was originally quoted--because not everything actually needed to be replaced. In fact, they told me it wasn't even close. What stands out most is their integrity. They're honest, kind, and incredibly helpful. It doesn't matter who you are--man or woman--you're treated with respect, and they never take advantage. I always leave feeling confident that my car received the best care possible. It's rare to find a shop like this, and I'm grateful I did. read more

I cannot say enough about performance Auto. Byron is car Jesus... he has resurrected my car from the dead multiple times and has really helped me and my husband out in some bleak situations. The entire team is incredible. Service is quick, reliable, and prices actually make sense. I am eternally grateful for this team! Thanks for all you do guys! -Liv and Eric read more

Amazing, quick, quality service. Needed a new mechanic as my previous shop is undergoing new management/ renovations, and these guys really stepped up for me. Def recommend! read more

These guys are simply the best. Family oriented, run and operated. They prioritize their work on you and your safety as a customer and not their bottom line. Most importantly, they are a shop that you can TRUST, which I feel like is hard to find in the world of mechanics nowadays. I was lucky enough to be referred over to them by a friend a couple of years ago, so take this review as your referral! You'd be silly not to come here. read more

I got a PPI done through these guys on a last minute notice. Josh and Bryan were very helpful and i definitely recommend them to everyone. They did a thorough inspection of the vehicle i was looking to purchase and were able to find even the smallest imperfections on the car. Hats off to you guys! read more

Great service and they are friendly and perform the work quickly. I would highly recommend them!

I can't say enough about Byron at Performance Auto. He was kind, very professional, fair, quick to respond etc. He replaced the engine in our son's Subaru Impreza. He went above and beyond for us. If I could rate him higher I would. read more

See all

Exceptional service. I'll never go anywhere else again! Byron and the team were friendly, efficient, and fairly-priced. They have all these 5-Star reviews for a reason, my goodness! Detailed: - Car overheated at 1 am - Towed next door to Fitzgeralds (friendly guys too) - Fitzgeralds said they could squeeze me in, but $170 estimate that would not be prorated/waived once we proceed with the job. Occurred on a Friday of a holiday weekend, so our negotiation Saturday morning was between a rock and a hard place. - Called around and luckily, Byron was right next door. He told me to bring it by and he'd take a look for free, given there were no jobs in front of me. - Of course, he cautioned me not to drive if the car was too compromised and informed me of the risks of overheating again. - After a 30 second drive next door, a friendly man named Byron approached me (his photo is on the sign, lol). - Car was already steaming up again, we popped the hood and he diagnosed it in another 30 seconds (LITERALLY). - I left the car in their care, but had difficulty arranging a pickup time, since I was on my way out of town for the holiday weekend. - Byron accommodated and even offered me a virtual method of payment and secured form of key pickup to meet my schedule! (Yet again, going above and beyond to make the experience A++). - I also called-in from out of town and requested additional hose and thermostat replacements, that he threw in for free (I checked the detailed receipt breakdown, and indeed, they were complimentary). - If you made it this far, you've found your last mechanic. Car problems suck, and 30 years of shoddy mechanic services make them suck even more. But if you've found Byron, you can finally say that you have yourself a good mechanic. read more

Performance Auto Service & Repair - Auto Repair Near Me - Costa Mesa, California

Byron and his team are fantastic! In December 2024, I needed to replace the water pump on my Toyota Prius. They completed the job quickly and at a very competitive price. The communication was excellent--honest, professional, and transparent from start to finish. I highly recommend Performance Auto Service & Repair! Unlike dealerships that waste hours of your time and charge excessive fees for basic diagnostics, these hard-working mechanics offer fast, reliable service at fair prices. They even run computer diagnostics for free, recognizing that it's a simple, standardized digital process--not something that should cost hundreds of dollars. If you're looking for an honest and skilled team that truly values customers, this is the place to go! read more

Byron is the best mechanic around! Hes honest, fair and goes above and beyond every time. Such great customer service! so glad I found him!

Byron is the best. He's a good honest mechanic who will charge a fair price. Relatively quick and easy to deal with I take any cars he's able to work on to this shop. Especially my 2004 suburban which still runs like a dream. read more

Was searching for an auto repair shop and I believe I found my home. Byron is very attentive I have his cell phone was able to connect with him on a Sunday when I needed to ask serious question about my car before I brought it in Monday. Love family-owned business. The location is clean efficient and prepared to do whatever needed on my car. Great pricing very competitive. I would recommend Performance Auto on Placentia to anyone with any type of car I happen to have an Audi and feel very confident. If I could give him 10 Stars I would. read more

5 Star Service from the beginning! Went above and beyond to help get us back on the road. Can't recommend Byron and his team enough. Only recommending Performance Auto Service from now on. Thankful for you guys! read more

Fantastic. I drove out to find an apartment and my clutch started acting up. I knew the problem. Called Byron and he took it in. He was no nonsense yet still super chill He was upfront with all pricing. Pricing was exactly what I expected. They also worked quickly! Don't hesitate to reach out. I'll only come here from now on read more

Honest, capable, AND great service?! I'm sold. I brought my older car in for some problems I've been dealing with for a while. Byron and Josh made me feel confident and taken care of. Their prices are very fair, and they didn't try to sell me on things I didn't need. They are my new go-to guys. Really grateful for folks like this in the industry. read more

Great experience. I had never been here and didnt know a mechanic aside from going to the dealership. Byron and Carlos helped me out, they were quick, knowledgable and honest. Hopefully I wont need a mechanic for a while, but if I do this is where I am going. Thank you guys for your help. 2020 Ford Raptor read more

Byron and his staff were truly professional. They diagnosed my car issues correctly and repaired them promptly. The truck would vibrate when I stepped on the brakes and he replaced my rotors and front pads. Walahhh vibrations are gone! Also he made me aware of a radiator coolant smell due to a leak. thi was my theory at first but couldn't find it. He actually saved me some money since I was due for a coolant flush anyway. Finally, I was missing 2 bolts for my engine shield and I noticed they replaced it when they put it back after the oil change! That was over and above ! Will be coming here for future need and telling my friends about Byron and Performance Auto Service in Costa Mesa! Thank you read more

10/10 would definitely recommend! I have been coming to Byron and his team for a few years now and have had nothing but good experiences. As someone who isn't as well versed in cars as others, it can be intimidating going to a shop and being confident you are being taken care of - but with Bryon I have always felt he is honest and transparent. Whenever I have issues (I have an older car) I can shoot him a text and he will call me straight away and set up a day/time to check out the car. In fact I just moved to Huntington and I still only trust him with my car! read more

Second time I have come to Bryon for a repair on a vehicle. This time, I unfortunately got a bad part and the car was making noise. As someone who spent most of their life working on their own car, I know that this does happen as it has happened to me where I have had to do a repair twice due to getting a defective part. Anyway, I had an appointment that's day as well as two other commitments I needed to drive to the following day. Since the repair didn't go as planned and I needed the car, Byron offered to pick up the car at my work, replace the part again it, and deliver the car back to me at my office in time to make my doctor's appointment. This kind of compassion and customer service is extremely hard to find in this world. I would definitely recommend Byron to anyone needing a vehicle repaired. read more

Byron is an absolute beast. He tested my alternator for free, he could of easily taken advantage of the fact that I don't know much about vehicles and charge me nearly 1k for a part + service but instead he told me that my alternator is actually healthy based on the testing and that I was good to go. I had my battery replaced recently and I thought the alternator needed a replacement as well but it turns out it was just the battery. Very ethical business, I highly recommend them as this was a good way to earn future business and trust. read more

Did a great job, on time, very happy with the service. Our first time here and the reviews were very accurate.

I took my Cadillac Escalade in to Performance Auto Service to fix brakes and a faulty trunk. The owner, Byron, identified the issues promptly and fixed both issues perfectly for a very fair and honest price. I am so pleased with the services here that I will only be going to this shop from now on. Believe all the reviews and try this place - it's rare to find such an efficient, thoughtful and fairly priced mechanic shop in Orange County. You will be happy you did! read more

Found this place by happen chance and so glad I did. Warped my head gasket on my Corolla. Byron was personable and empathetic to my situation. He gave me a couple options on what was possible. Either change the engine out or try and fix it. Both were expensive. We decided to go with the new used engine. All together I paid a little over $3000 and it was a complete deal! Byron is A1 when it comes to what he does. I would recommend him to anyone needed car maintenance and he will be my mechanic forever. read more

Got a buyers inspection here and was so thankful for the help of Byran and the whole team who were incredibly helpful, thorough, patient, and kind. I planned to buy a new car but wanted to get an inspection first to avoid buying one with issues the used car salesman may be trying to hide. Thank god I did, because the team at performance auto service not only found issues with the car but kindly explained them to me and gave advice about how to move forward. They saved me a real headache by helping me decide not to purchase the car and made me feel supported throughout the process. Not to mention the inspection was speedy and I got the car back within an hour. Can't recommend this shop enough!! read more
