My Auto Guardian Angels!!! Been coming here for well over 15+ years for fantastic service for my older 2003 Acura before selling it, and now my 2017 Hyundai Santa Fe on everything from simple oil changes & windshield wipers to breaks, struts, alternator, timing belts, water pump, transmission issues, etc. What really locked me in is when talking to the owner Khoi he made a point on telling me they have a special point of looking out for women, single mom's etc. because he knows in this industry, they're often easy targets for mechanics who prey on women. Totally admired him for that. I know the whole team Gene, Khoi, Andy, & TJ (has changed a bit over the years), but still same great service. I should have posted about them well over a decade ago, but after having my car serviced yesterday (12/29/25), TJ & I talked about an issue he specifically helped me with last year when I was in a battle with Hyundai Dealership staying compliant on fixing a "Rod Bearing Failure" recall issue that requires an entire replacement engine install due to my car was experiencing serious stalling, slowing down in the freeway, and drastic oil burning out to the tune of needing oil fills every 2-weeks!!! One of the Hyundai Service Specialist advised I NOT refill the oil and just let it burn out until the engine locked or a specific service light switched on. I told her that sound awfully drastic and dangerous, but she said that would be the fastest way for them to get the proper engine "Rod Bearing Failure" code reading they needed to warrant the engine replacement. Needless to say, no oil caused the catalytic converter to blow out. Now, the Hyundai Specialist comes to me singing a new tune that it's now MY responsibility to pay $4500 for the Catalytic Converter to be replaced NOT addressing the new engine at all. I immediately hopped on the phone and followed up with TJ at Factory Specific, not only did he fully consult & educate me on the EXACT steps to take to make them address and fix ALL issues including the Catalytic Converter but that I could take it up with Hyundai Corporate office as well if necessary, bottom line do NOT let them off the hook. TJ's ADVICE WAS AWESOME; I GOT NEW ENGINE & CATALYC CONVERTER REPLACMENTMENT AT $0 COST, PLUS A NEW 2025 HYUNDAI SANTA FE LOANER CAR FOR ABOUT THREE WEEKS!! My Auto-Guardian Angels! ;-) Sorry this review so long, but I had to put this story out that might help someone else facing a similar recall issue and having difficult time in getting the dealership to keep their word! FACTORY SPECIFIC - Always fair pricing, awesome friendly fast customer service with a smile- good group of guys. I will refer them ALWAYS! read more

Had Factory Specific do electrical work. As usual they did a great job. Very happy with the work they did!

Tbh I'm not sure what I can add that hasn't already been said about this place -- the great reviews are well deserved. I came in with a couple of issues, and the staff was incredibly helpful, understanding, and efficient from start to finish. Everything was explained clearly, and the whole process felt easy and stress-free. I decided to come back a second time bc of how smooth my first experience was, and they were just as great the second time around. It's such a relief to have found a shop I trust, and I can def see this being my go-to repair shop moving forward! read more

Ahhh Factory Specific my family and I have been going here since I was born I practically live there, the way we visit is like the employees are like family and the trips are mostly short because of how fast they work! The costumer service is beautiful and they don't try to argue, they always try their hardest to come up with a compromise. The price is to the perfect amount they don't try to scam you out of your money like other shops,and the inside decor is very pomp for how old this shop is. All of the consumers I've met have said it the best auto repair shop they've been too! read more

Took my car over here for an exhaust swap and couldn't have been more happier . I was going to take it to another shop in Fairfield but the owner rubbed me the wrong way so I decided to take it somewhere else.. I just happened to find khoi's shop while stopping by to visit a friend in the same lot. Not only did I get a better price (by far) Khoi also did a couple extra things I need done free of no charge .. really great guy and proud to have met him .. if your looking for a good business that u can trust look no further and give them a call down at Factory Specific . Thanks again guys read more

See all

Very friendly, and upfront on the issue. It's nice when all my family members bring their vehicles here and the establishment recognizes the name. My car runs smooth, my brakes are replaced and I look forward to the next visit. read more

Best car mechanic in town for Japanese imports, and probably for other makes too. I've only taken Hondas, Acuras, and Toyotas to them. Khoi and his team provide great service at very competitive pricing. I've been a customer for around fifteen years. read more

I haven't taken my car to their shop in a few years, due to the difficulty they had diagnosing a blown head gasket. I didn't like how that experience went. I had taken my car there 3 times in a few months for engine overheating issues and tried being as descriptive as I could with the front desk about what I was experiencing with my car. After the 3rd time, the tech told me, you should've been more specific. I didn't agree with that. Shortly after, my car got diagnosed with the blown gasket. I understand the diag can be tricky with blown or partially blown gaskets but still, they had my car, I figured they could figure it out. Maybe on their end they didn't want to jump to worst case scenario. Idk. They had tried other things before the blown gasket. During that time period, one of the times I left my car at their shop, I got my car back with a ding on my exterior door trim. I wasn't trippin about it too much because at the time my engine was overheating so I needed to deal with that. But I didn't like that it happened when my car was in their possession. Before this issue, I had taken my car there several times for oil changes, tune ups, timing belts, etc. I always had good experiences with them with stuff like that. I like that they give you the option to go with aftermarket or OEM parts. At the time when I was taking my car to this shop, they weren't the cheapest and weren't the most expensive either, but the quality of the work was always solid. read more

Solid auto repair shop! Just went in to get '06 honda serviced and TJ the auto technician was very detailed about what needed to be done to the car. They are super helpful and honest when it comes to priority services you should have fixed as well. Pricing wise they are great too. I will def come back! Thanks guys. read more

Honest and reliable! They truly know the meaning of customer service, they treat everyone with the same level of respect and courtesy to ensure that the customer is heard and understood. read more

Khoi helped me with my Nissan needing a new Transmission. He was very detailed, and patient with my questions and explaining the process and options for my car. Very happy I left my vehicle in their care: my car came out with no further issues. Glad I found a reputable shop for all my car needs. All my services requests were met and for the price expected. read more

I was referred to Factory Specific by a friend and I am very happy with the work and timing. One morning my car started shaking badly. I called and made an appointment. They got me in quickly. I had family coming to town and was worried I would not have my car to pick them up. It was done fast and I was available to my family. It meant a lot to be able to do that! TJ was a great help. Very knowledgeable and friendly. He explained everything very well. Thanks TJ! I don't live in Fairfield but it's worth the drive to see them. My car is running great! She's old but she's got more life in her thanks to these guys. I appreciate the time and care they put in. read more

I have a 2010 Chevy Avalanche that needed new cooler lines trans cooler lines pinion seal and oil pan gasket and sway bar endlinks changed. Khoi once again came through as always! I will not take my vehicles to any other shop. Tj at the front desk is also kind and helpful. The shop is very welcoming and doesn't feel like the typical shops where your going to get ripped off. Thank you guys for getting me back on the road. One happy customer read more

Called two days ago for an estimate on brakes for a 2015 Honda, they took info and said they would call me back, never heard from them....... read more

I have been taking my cars here for 6 years, they never disappoint me. They are fast, reliable, provide excellent and honest service. You cannot beat the quality of their service, integrity and prices. read more

My new place to go for both my Honda Accord and Pilot. Dealt with TJ for both of them. Recently brought my 2015 Pilot as I have been neglecting to get it serviced just due to being crazy busy. Being that it's summer and time for roadtrips, I finally got it serviced. I was able to get a morning appointment. TJ gave me an update on my car and I relayed it to my husband just because he'd know more carspeak than me. LOL Friendly, and honest when it came to pricing! I know for a fact I saved more than taking it to the Honda dealership to get it serviced. read more

We have taken our four cars here for service. TJ has always been very professional and extremely helpful. Khoi and his team do a great job analyzing the issues of my vehicle and recommending certain services. This is my place to go for my oil changes, diagnostics, inspection, and transmission issues. There's no upsell... just straight to the point. They have taken care of my Kia Sorento, Toyota Corrolla, Camry, and Honda Civic. I highly recommend FactorySpecific. read more

I have a 2016 Lexus ES350 which has 33,000+ miles after 7 years and the cost of the maintenance was very reasonable compared to the Lexus dealer. Customer service was excellent, it was worth the drive from San Leandro to Fairfield read more

Made an appointment for my mom's car to fix the AC. The diagnosed, gave me a call on price and knocked out the fix the same day! I would highly recommend this place! read more

TJ and Koi are very helpful. They explained everything in a thorough manner. They worked with my schedule to set my appointment. They are very knowledgeable and reliable. They took care of my car in a timely manner. I highly recommend! read more

Friendly, honest, excellent work and reasonably priced. I've been bringing my cars here for years. My only complaint: sometimes it's hard to get an appointment because they're so busy. Highly recommend!!! read more

Brought two of my cars in for timing belts. Afffordable, good work, and clear communication. Will bring more cars in the future.

I was told by a different shop that I needed my brakes and rotors (and many other misc things) replaced immediately for a total of 1,500. I lost my trust in that shop and decided to get a second opinion at FactorySpecific. Not only was FactorySpecific up front with me about their prices beforehand, but they took my car back and provided me with the results in less than 30 minutes. They let me know my brakes are at 50 and 40 percent of their lifespan and no service needed to be completed at this time. Although FactorySpecific did not service my car today, I will absolutely be bringing my car here for future needs. read more

My mom, my sisters & I have been going to Factory Specific for close to a decade, so I have no idea why I haven't reviewed them yet. Khoi & his team have done just about everything on our family cars - from major fixe to oil changes - and they have always done right by us. I moved to sf, but when I came to visit my family in Fairfield, I went by Khoi's to get an oil change, because I value their service and how well they do their work. They're priced fairly, they do a great job, they have great customer service and you get the small business pride out of how they run their shop. As long as Khoi has a shop, he will have our families business. read more

I started taking my Honda Pilot to them in 2014. They're honest and their customer service is awesome. I now take my Lexus and Infinity to them and they take very good care of me and have the most reasonable prices. I refer them to everyone I know. read more

My buddy's Nissan broke down in Fairfield and this shop came through and fixed it right, the first time, at a reasonable price, while communicating effectively throughout the process, unlike the last shop that tried to fix the car and failed. They let us supply our own parts because we work for an auto parts company, which was nice. read more

These guys are the best! I've been taking my Nissan Pathfinder (2015) here for the last 3+ years. All my oil changes, break work, air conditioning has been taken care of here. They are very courteous, upfront with cost estimates, keeping me informed with may be need soon, never pressured into repairs, and when the repair ended up taking more time they have given me a ride home, I live close by. They have integrity which isn't easy to find nowadays and they do great work. read more

Servicing my Honda and Toyota since 2021. Great communication, fair prices, quality service.

Best prices in town! While all places including the dealership are charging over $100 for an oil change Factory Specific keeps their price low! Recently brought my car in for a power steering leak and TJ was very detail about what work was needed. I trust this shop and will continue coming here in the future read more

The best place to bring your car for service and repair. Staff are friendly, helpful and honest.

Took my van in for a major servicing. They were efficient, supplied a complete record of the vehicle maintenance, understood my requests, and finished three hours ahead of the scheduled time. They were unable to balance the tires, but fulfilled all other requirements, at half the cost of a dealership. Since this is my first time utilizing this business, only time will tell of the worthiness, but so far, I'm impressed. read more

The team here cares and take pride in providing great customer service while keeping prices affordable. I stop going to the dealerships and have always been satisfied with the service provided by Factory Specific. read more

TJ and the team are the real deal! I needed some work done on my RAV4 and I came a crossed their Yelp page and read nothing but great things! I decided on giving them a call and getting my car in. Everything you read about this shop is 100% accurate!! If you need work done come here before going to the stealership. Their prices and work are unbeatable and their customer service is on point! TJ sat me down and went over everything that was going to be done on the car and had great communication through the process by phones calls and kept me in the loop as what was going on. I couldn't be any happier for the work that was performed and price that was given! Going forward, I'll take my car here for any work that needs to be done. Shop that can be trusted! You won't regret taking your car here, I guarantee it! read more

I've been going to this shop from day 1, the owner of this shop, Koi, is very professional and upfront with you. Prices are very resonable. They tell you right away what the problem and very honest with their work. If it needs to be done, they will get it done. No bs! Highly, highly recommend this shop to anyone that needs car repair. read more

I found these guys calling around for quotes when I needed a brake caliper replaced on my Camry. They quoted me a very reasonable price for the repair, and to install the brake pads and rotor I already had, and worked with me to get the work done ASAP. Good guys who do good work at decent rates; highly recommended. read more

Amazing place. Andy, who I believe is the master mechanic for the shop, knows what he's doing. He's very mindful and I can tell he likes, if not loves, what he's doing. The guys in the front are very friendly, welcoming and both them and the mechanics, are open to talking with customers if there are questions. It's a clean office, as well. I've seen them sweep and there's good communication between the front and back as Andy once came to the front to talk to me unprompted but was needed so the job could be done right. I do my own work and when I can't I bring to a mechanic. I've lived in the area for over 20+ years and have dealt with various shops and I've always had bad experiences which is why I've learned to take care of my cars out of necessity instead of dealing with people. Several times I've made appointments and this place has stuck to them, which is more than I can say for other shops. The work they've done on my car was minimal but I can't do it at my house. I've inspected their work and they've done work that is, at the minimum, as good as mine, if not better than mine. They stick to the book, which is like because it tells me they're not cutting corners and when they said something is wrong or could go wrong, their evaluation was not wrong. Khoi is very concerned with keeping his shop at a certain standard and that is extremely hard to find. As I've said previously, I've lived in this area for 20+ years and dealt with many shops and all have failed me. I can tell you in full confidence that as of today, this place is a diamond in the rough. read more

Exceptional service from everyone!! I bought a 2010 Honda Civic a few months ago and it was running pretty rough. The suspension was making all kinds of noises, and the AC wasn't getting cold. Took it to Factory Specific to have it diagnosed. The friendly service advisors kept me informed throughout the whole process and always made sure to provide me all the information I needed to make the right decision in which repairs to have performed. I never felt pressured to have anything unnecessary done. Thanks to the very knowledgeable mechanics, my car is running like new. I was thinking about selling my car before taking it to the shop but now I'm definitely holding on to it. read more

FactorySpecific - No longer for sale - Auto Repair Near Me - Fairfield, California

I took my 2001 Lexus LS 430 into the Lexus service center in Concord, they quoted me $1200 just to diagnose and figure out what was wrong, that didn't include any repair or parts that would need to be ordered. My dad found FactorySpecific by searching for places that know how to work on Lexus cars, and I brought in my car here. Immediately from the start I felt much better about what was going on with my car and knew I and my car were in good hands. My car ended up being there for 2 weeks, but by no fault of the guys at FactorySpecific. Over those two weeks, TJ would call to give me updates and give price transparency so I knew what I was in for. I appreciate TJ and all the guys at FactorySpecific so much. I will definitely be coming here in the future for any auto-related needs! read more
