    I needed a clutch replacement for my Scion FR-S. I was unsure where to go being new to the Bay Area. I came across Horsepower Industries in Fairfield. I am extremely happy with the outcome. My car is running like a charm after a the team took care of the whip. They also surprised me and fixed my e-brake that was giving me issues AND washed my car. Overall, I am 100% pleased and will continue doing business going forward.

    I went to horsepower industries to have my rotors and pads changed as this was something I haven't had done since i purchased my car (i know i know) Karlo was great, performed the service and gave a fair price. We ended up using R1 Concepts rotors and pads to give the car a bit more bite for breaking. Horsepower Industries is a great place to take your vehicle for maintenance and your aftermarket needs. Thanks again Karlo!

    I am originally from Los Angeles, I had taken my Toyota MR2 to s specialty shop called FSR Motorsports Creation. I had asked them to adjust my coilovers. That was 2 years ago, no wonder the car felt like crap. Brought my baby to Horsepower Industries, i asked that they go through the car. One thing they did was adjust the coilovers. WTH, I thought the tuner shop in LA did that. Thank you Karlo. He also did my 4 brakes, and rotors in less then 3 hours, and that was including my coilovers adjustments.

    I've used Karlo multiple times for multiple cars (DSM, S2000, Mustang) and man does he know his stuff. Great work, great customer service and great guy. Make sure you check him out.

    My 5.0 that Horsepower Industries will be helping me get back on the road very soon!

    I was told by a real car enthusiast and a friend of mind that Karlo is the man when it comes to getting anything done on cars. So I decided to go check out the shop. To my surprise Karlo was a real straight forward dude with the best prices "Ever"! Thanks Rogemar. You hooked me up.

    Horsepower Industries is a great place to take your daily driven vehicle for maintenance services, as well as performance upgrades. Courtesy, cleanliness and quality are the things that make this shop really stand out, another thing that I really like is that the business is family owned and operated.

    If only I could add ore stars to this review, the guys over at HorsePower are awesome! Great service and very knowledgeable. I've taken my WRX to them multiple times for maintenance and installs for mods. Super friendly and down to earth guys, the only shop I'll be taking my car to. Their mechanic Jon and owner Karlo are great with what they do! Great job guys!

    My Auto Guardian Angels!!! Been coming here for well over…read more15+ 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!

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

    After calling a few mechanics in the Fairfield area about having a pre-purchase inspection on a…read moreVolvo, I decided to go with Auto Repair Solutions because it had the highest number of Yelp Reviews in the area for European cars. After arranging the inspection on a Friday morning, I waited to hear back from the mechanic after the buyer told me the car had been inspected--NOTHING for hours. I tried calling Jeff (the mechanic) several times, leaving messages each time without so much as a callback. When he finally called me back, he didn't tell me anything about the car except "it looked good". I asked if he had taken any photos of the car or if he had any kind of report he could email or text me and he said "no". I asked if there was anything specifically about the car that I should be aware of for the future--something every mechanic can comment on--to which his reply was, "Not really." As someone who has had several PPIs from different mechanics over the years, I've never been told that there was no inspection report at all--nothing about the tires or the brake pads or the filters or fluid levels or the body of the car or the interior. NOTHING. So, by the time I rescheduled anther PPI with a different mechanic on the following workday in the area, the owner ended up selling the car I planned on buying.

Jeff's shop was recommended to me, Ironically, by a tow company. They said he worked on European exotics, so I thought I'd give it a shot. Took my car in for shock replacement on a Thursday. Got my car back Sunday morning, which included a new shock being overnighted, delivered and installed Saturday. Jeff did a great job. 3 things stood out regarding this shop. 1.his outgoing voicemail message is updated daily with the day, date and next appointment availability. That is huge because you know The approximately lead time you're looking at. 2. he's open on weekends, which is fantastic. Most shops are closed on weekends which is when bad things happen. LOL. 3. Genuinely good customer service. He takes time and explains the issue and the solution. That's invaluable. Great job Jeff, keep up the excellent work.
