Friendly, affordable, and quick. Just bought a 2024 Tundra and this will now be my go to place for anything I need done to my truck.

Called this shop to get a quote for a basic oil change on my Jeep Wrangler and was honestly surprised when they came in about $100 higher than the dealership. When I asked why it was so high, they mentioned it included some kind of "warranty" with the oil change. That didn't really make sense to me for such a standard service and felt more like an upsell than actual value. I'm all for paying a fair price for good work, but for something as routine as an oil change, I expected pricing to be at least competitive with a dealership...not significantly higher. Ended up going elsewhere. read more

I brought my car to OC Automotive Diagnostic to repair a busted headlight lens. From the start, the experience wasn't great--the front desk staff had a dismissive attitude when I first dropped off my car, which already gave me a bad impression. After the repair, I noticed that my headlights were dim while driving at night. When I checked under the hood, I found that one bulb wasn't plugged in correctly and the other wasn't installed at all. It's frustrating to deal with this kind of sloppy, careless work, especially on something as important as lighting for nighttime driving. Between the poor quality of the repair and the lack of professionalism at the front desk, I won't be returning and can't recommend this place to others. read more

I appreciated how kind and pleasant the manager and workers were during my visit. However, I was disappointed with the overall cost of the service. I only needed an oil change and a tire-pressure check, but the total came out to $120. At my previous shop in Fullerton, I usually paid around $80 for the same service, so the difference was surprising. I also noticed a charge for rags and gloves, which didn't make much sense to me. While I chose this place because of its high Yelp ratings, the pricing just wasn't a good fit for me. I'll be returning to my original shop in the next town over for future services.. read more

Have had multiple services done here through OC automotive, am always happy with the quality of service when Anthony helps us. However, we will not go back due to Gabriel being constantly rude and unhelpful in person and over the phone. It's nearly impossible to make an appointment and Gabriel will constantly cut us off and argue with us when the situation does not need to be combative. read more

We came here because of the high reviews and we were very disappointed. We were given a price for for a headlight replacement that was over $1500 that we agreed to get fixed then get a call that another piece they need will be about $100 and we agree to that. We finally go pick up our truck and both of the wheel moldings have big gaps and we're not put back together correctly. They said that's how we took it in. Lies! But I guess that's the kind of work they want to be known for. They then charged another $40 for $10 clips to put in the clips they broke. We will never go back! Beware! Do not deal with Gabriel. read more

Everything was excellent. They even picked up my car from my house. I will definitely be coming back.

Great service with fair prices! Very friendly and considerate. They care about the community and taking care of everyone they can. Highly recommend! read more

Highly recommend Orange County Automotive and diagnostics. It was the best experience I have had trusting my Jeep to a mechanic in years. They were able to find and fix a problem that I've struggled with for 2 years and had 2 other mechanics fail to fix- and paid them less to fix it than I paid to each of the others not to fix it. I love driving my Jeep again.... Anthony is wonderful to deal with- I already told my neighbor about them. A reliable mechanic is a wonderful thing to have, and I have finally found mine. Give them a call- you'll be happy you did. read more

I'm so thankful that I found this auto repair shop! Anthony & his team are the best! They always do a great job & never pressure you for services you don't need. It's so nice to be able to trust a shop that will do what's best for my vehicle. Highly recommend! read more

After years of looking for a reliable place for auto repairs I found OC Automotive on Yelp and now they're my "go to" auto repair shop. They're fair, knowledgeable, and professional. Anthony is always patient with questions and he gives detailed explanations of needed repairs and costs. His staff and mechanics are also knowledgeable and professional. My experiences with OC Automotive would rate 10 stars if that was allowed. read more

I understand why they are so highly rated. These guys are fantastic. Took car in for a diagnostic check, and they couldn't be more helpful. read more

Anthony, Jacob, and the guys were great! I used RepairPal to reach out to several repair shops to get an estimate to remove and replace wheel stud and stripped lug nut on my Civic. OC Automotive & Diagnostics provided an honest price for the parts and labor that couldn't be beat by the other estimates I had received. My appointment was scheduled for 9 a.m. on a Monday morning. I got to their shop early and turned over my keys as soon as they had their bays open. I was pleasantly surprised by their comfy customer lounge area. It smelled of freshly spritzed air freshener. There was also counter with a variety of Keurig coffees and teas available, and small bags of cookies too. After about 45 minutes, I got a text message with a link to their electronic courtesy inspection. I was pleasantly surprised because I didn't know that it was included with my work order. Their report included pictures of various checklist items such as oil level on the dipstick, tire treads, brake wear, brake fluid, front & rear suspension, and air filters to name a few. It's a good reminder that some of these items are not DIY. So, I will be returning in the future to take care of some of those items. I also got a discount for a Yelp check in and paying in cash. The shop will add a service charge to the bill for using electronic payment. It was very nice to receive a follow up text from Anthony asking if I was happy with their work. I can't recall ever receiving this level of customer service from any repair shop. Go see these guys for your vehicle repairs. read more

You will not be disappointed with choosing OC automotive for your car needs. Thank you again to the team for excellent service and experience! read more

These guys are so nice! I'd go back for an oil change, but my experience was for electrical issues. I thought the OC Automotive would be cheaper than the dealership, but here is how the costs compared: OC Automotive and Diagnostics: - diagnostic fee: $450+ - estimate for fixing my vehicle: $5000+ - length of diagnostics and tests: ~4 days Dealership - diagnostic fee: $220 - estimate for fixing my vehicle: $0 - length of diagnostics and tests: 1 day OC Automotive is great at being transparent and keeping me informed on what's going on, which I loved, but ultimately they were not able to fix my car or come up with the most efficient solution, which led me to get a second opinion at the dealership. I think the staff is great, but I'm not sure if I'd go back for electrical issues. read more

As you get older you start to realize you need a few things that are sure bets. A great hole-in-the-wall restaurant, a financial advisor you can trust, and your own mechanic. I've lived in Whittier for 4 years now and though I have a mechanic he's far from where I live. So based on the recommendation of my friend I decided to check O.C. Automotive and Diagnostics out for a tire rotation and oil change. It was a good choice. On The Phone Currently they are taking reservations for service only. I called in and found that you need to reserve a day or two out so if you're expecting service day of that might be difficult. They were friendly on the phone and the questions they asked seem all relevant to what I was trying to get done. In Person When I arrived in person the waiting space was comfortable with both benches and couches to sit in. I knew it was going to take about an hour to get everything done so I brought my own entertainment to keep me busy. The person in the front was friendly and we had a little banter about my car. He seemed to know about cars which is comforting from an automotive shop. He frequently gave me updates when I asked and the hour passed. Post Service When they finished with my car the owner/mechanic came to me to talk about the service they did on my car. They also did an overall inspection and made recommendations of what I should do for future maintenance and what to look out for. They also emailed me all of the info they were sharing with me so that I could take a look at it if I decided to get these things done. There was no selling me anything I didn't want or trying to be hyperbolic with the condition of my car. It was truthful, straight forward, and pleasant. I left feeling satisfied not only with the service on my vehicle but also how I was treated, even as a new customer. If you live in the Whittier/La Mirada/La Habra/Hacienda Heights area I highly recommend checking this place out if you're looking for a mechanic. They are professional, efficient, and truthful at a competitive price. read more

I took in my truck in for electrical issues. I couldnt leave it at the shop longer than 3 days so the issue was not resolved. However, the owner was outstanding with how he explained what the problem could be. As a female customer he treated me with respect. The problem with my car has not returned as of yet but I will definitely take it to OCA if it does. Thank you. read more

I had a great experience with OC! I've been looking for a reliable mechanic in my area and found OC after seeing the positive reviews on Yelp. I had a list of recommendations from the dealership and Anthony and his staff looked at my car and went over each one with me. Anthony was great- he was very patient and answered all of my questions. I felt he was very honest and the pricing was transparent. The prices were fairly close to the dealership but I really trusted Anthony and felt his staff would do a good job, so I had him do the work. My car is running great, and I'm very happy I now have a reliable, honest mechanic I can count on. Thanks Anthony and OC! read more

The best auto repair shop I've dealt with. I recently had 2 vehicles in need of repair at the same time. Anthony, Gabriel and their team quickly diagnosed and fixed an issue with one of them after a previous mechanic could not. They are honest and straight forward and they act in the best interest of their clients. I witnessed the latter as I overheard them talking amongst themselves about another client. I know that I've found someone I can truly trust. read more

OC Automotive and Diagnostic recently worked on our vehicle with a strange water gushing sound in our dash. They found the problem in a few days, and the cost was very reasonable. They really care about getting your vehicle running correctly when it leaves their shop. Best repair place I've been to in a very long time read more

O.C.Diagnostic helped with diagnosing a problem with my wife's Kia Sorento and they Did some repairs on it and they took care of it. very upfront and honest with the repair and service.So far my wife's car is running good thanks guys! read more

I was sent there to have a safety inspection done on my car since I drive for work. The inspection was quite thorough and could have take much longer than it did. I did arrive earlier than my scheduled appointment in hopes I could get in and out to beat traffic back to the LBC where I live. Since I was early the team was still on their lunch break. I assured them I did not want them to cut their lunch short to accommodate me and to please relax and enjoy their meals. The owner, Anthony, would not hear of it. He quickly had me fill out my paperwork and told me he would take care of it himself. And he did. I stepped outside to take a call, and was pleasantly surprised when the call was cut short by Anthony approaching to let me know the inspection was complete and I was free to get going with my day. An added bonus, was he informed me before leaving that my car had passed on all aspects of the inspection and that he had already submitted the findings or lack there of to my employer. Now that's what I call customer service! I have and will continue to recommend OC Automotive to my friends and family. Even if it's an hour away from me. lol. read more

absolute worst honest diagnostic . recommended a local guy( not recommend) and took it in diagnostic. long story short they found the issue cool for them but the issue they said it would be 1500 extra and so I said no based on price and issue, ( I took it in for a second option at the actual jeep dealership and damn wouldn't you know it, it was 499 with parts. ) Hummmm. ) what a damn shame for you guys. be honest next time and you won't loose business. don't trust these guys. they are out get you for you money. after further talking with Anthony and explaining. I can respect him as a business owner and understand the ridiculous (Biden) prices we have encountered. I support and respect local business owners and as a local resident I hope and pray for nothing for the best for OC automotive. Make America Great Again. read more

I always take my vehicles to OC Automotive and Diagnostics. They do very good work and keep me informed of what is found. Recently, I had headlight, battery terminal fuse and battery issues. AAA towed my vehicle to OC as requested. They repaired and replaced everything that was needed. My vehicle is operating as it should again. My thanks to Anthony and his techs for handling this situation read more

I've had my 2011 Hyundai Genesis Coupe stuck in repair since December 2022 with serious electrical problems,no start, bad ECUs, and immobilizer issues. I went to FIVE different shops between February 2022 and July 2024, and each one either misdiagnosed the issue, charged me for useless repairs, or straight-up refused to work on my car because it was "out of their control." I wasted time and money, and my car ended up worse off after every visit.Then I decided to give OC Automotive and Diagnostic a shot. Honestly, I didn't have high hopes after everything I'd been through, but these guys surprised me. Gabe, the service advisor, laid everything out from the start--parts, pricing, and a solid timeline for the repairs. No BS, just straight talk. He even stayed late a few times to make sure parts were ready to go. Every promise he made, he kept. That alone put them miles ahead of the other shops. Kris, the technician, was another level. I told him everything about the car's history with other shops, and he took it all in, gave me a confident smile, and said he'd get it running. In less than a week, he had it back on the road. This guy didn't just fix my car; he cleaned up the mess left by everyone else--reconnected cut wires, reinstalled missing panels, and figured out issues nobody else could. He knew exactly what he was doing and got it done fast. Anthony, the owner, also deserves a shoutout. He broke down their whole troubleshooting process step-by-step and didn't leave me in the dark about anything. He's the type who cares about his customers and is willing to go the extra mile. He even threw in a free air freshener and a discount card, plus he gave me a discount on the overall cost. After all the headaches with other shops, that meant a lot. Bottom line---- If you're done with shops that overpromise and underdeliver, go to OC Automotive and Diagnostic. They know their stuff, they don't mess around, and they actually deliver. This is the only place I'm taking my car from now on. Highly recommend. read more

Solid guys, honest work! Fixed my truck on the fly so I could make it home from work!

I had a GREAT experience with them! My brakes gave out on me because I had a cut in my brake line and ran out of fluid. They happened to be able to get the special order part I needed right away and fix my car within a few hours RIGHT at the start of a holiday weekend! Super helpful and quick, efficient service! I would highly recommend this place! Very hospitable and made sure I had everything I needed. read more

The team did a great job on my Porsche. For years I'd have to go all the way to Norwalk to get service. Glad I found you guys right in the neighborhood. Very impressed with the quick turnaround on major service and repairs. dash lights are all gone and the car runs great Thank you all read more

Hello everyone, OMG!!! This guys are awesome. My A/C is working again and cold like I like it. When my A/C went out last year and winter coming I decided to hold on repairing it. Well now the heat is coming and I knew I needed to find out what happened to it. I checked things I could do myself and still not working. So I took it to the only people I know I can trust with my car, O.C AUTOMOTIVE AND DIAGNOSTIC. They did a EVAC DIAGNOSTIC on the A/C system and found out it was only the Compressor. Everything thing else is working good. What I like most about O.C Automotive and Diagnostic is they only but in dealer manufacturing items. I took my car to the dealer just to find out how much and how long it would be. The first thing out of their mouth was, I would need to leave the car for three days. I ask, it would take three days to work on my car. The guys said yes. I told them, thank you but no thank I need my car. (Not to mention the price for the fixing the of it... unbelievable). This why I can only trust the guys at O.C AUTOMOTIVE AND DIAGNOSTIC, they are true to the words. They had my car fixed within a day. (Same day) Please keep in mind that parts from the dealer need to be order. But the owner ANTHONY will be able to assist you with a more understanding with what the s going on your vehicle. Please also keep in mind, O.C Automotive and Diagnostic works on Classic vehicles and present vehicles. Like I said in the beginning, these guys are AWESOME!!! Get your A/C done now, not later. It may cost you more in the long run. Thank you guys read more

Excellent and trustworthy service!! I'd rate a 10 If I can! We've taken our cars to OC Automotive for a couple of years now and it's been great every time. There's never any pressure of getting things fixed that are not necessary. When little things do come up Anthony let's us know and leaves it up to us to decide. Unless it's serious of course. But again, we've never had any problems!! I've referred so many people and will continue. We actually have a certified mechanic in the family too (shh.. don't tell him!) haha! But still decide to take our cars to OC Automotive! Keep up the great work guys! Thanks for keeping our family safe on the road! God bless! read more
