Ken and his team were able to fix a problem on my older Toyota that had stumped the dealer. Polite, honest, hard working. 5 stars.

I had a very good experience with Concord Auto Service. My repair work was very minimal, I was able to txt a pic to Ken, get an estimate and bring the car by on the same day. They have a waiting area, or can bring a chair for you outside if you want to wait as your car is being worked on. Their price was fair and they are very professional. read more

Found this place on yelp and was very happy with my service! Ken was up front & honest about what was wrong with my car & how much it would cost. I will be back. Thank you, Ken! read more

Absolutely amazing shop. Ken is amazing!! I had an unknown problem with my car and he was able to fix it very quickly and with excellent turn around. I will be back for any other issues I may have with my car and will tell everyone to go and see Ken. Thank you Ken for your hard work and dedication in these hard times of Covid. You deserve all the best!! read more

Ken is very professional and nice to work with. I left my car, a European model, which he checked but couldn't do the repairs. He didn't charge me even though he had it overnight. Will definitely bring back our other cars if needed to Ken. read more

I needed to get my Axles replaced and my transmission fluid drained and changed and they did it all! The owner is a nice guy and he was fun to talk to, and he actually tried getting to know me, which was actually really nice. I just moved to Walnut Creek and so am looking for a place to routinely service my car and I will definitely be taking my car here. I trust the work they do, and I feel that they have the best interest for my car. read more

Ken is the best! So are all the guys in the shop, always willing to help. Love this place

If you're in need of competent, honest and reasonably priced service; you've found the right spot. I have my families cars serviced here when it's something I can't do. Make sure you ask for Ken! I'm happy I have a place I can trust! read more

I had a great experience at Concord Auto Service. I wasn't quite sure what was wrong with my car, so I did my best to explain, and Ken knew exactly what the issue was. They were able to get my car back on the road much sooner than expected. I highly recommend everyone to get their cars worked on at Concord Auto Service. read more

Concord Auto Srvice Ken Barsabal and his team of mechanics always perform excellent service on my vehicles from past to present for oil changes, brakes and some major engine problems they always been able to keep my daily drives dependable and safe. read more

2002 Subaru WRX wagon, 85k miles, never had any major repairs or major maintenance. I took it in to replace the valve cover gaskets, which were oozing a tiny bit of oil that made the car stink. Ken found additional drips coming from the front of the engine and I approved a timing belt kit replacement along with new water pump and oil seals, and other bits that were accessible. The work was done right on budget, and the result is very pleasing - I've fallen in love with my old car again. It purrs and runs more smoothly than it has in years. No more stink! A big thumbs up! read more

Love this place!! Friendly staff, very knowledgable! Best around!! I won't go anywhere else! Sending everyone I know here!!!

Best mechanic you can find. Honest reliable work. I took a car I had just bought a coupe months ago in to get 100k service. After looking at my car I was told no work was needed that it looked like the service had already been done. Anyone else would have charged me and not been honest. Ken is the owner and not only is a good businessman but he is also good for his community, doing fundraisers and sponsoring local kids. read more

Service Department was great. They are very attentive to their customers and everyone was super nice!

Went to Concord Auto Service yesterday based on Yelp ratings. Did not have an appointment at 2 p.m. on a Thursday afternoon so I wasn't confident I could get a repair that day. The sense of urgency was due to my brakes suddenly being very unreliable. I drive to San Francisco regularly. Bad brakes and San Francisco do NOT mix, not unless you are looking to start a trend of being a hood ornament on a cable car. Happy to report that Ken took great care of me. He managed to squeeze me into his schedule and personally undertook the repair. He was straightforward with me. Pointed out another repair that is needed, but stated it didn't affect the reason I came in, which is the braking. It was not immediately apparent what the problem was, as the premium brake pads I had on the car still had plenty of pad left. Final consensus was that the culprit was likely overheating of the rotors resulting in poor stopping power. There was evidence of this, and they were standard non-vented rotors, so they possibly could not hold up to the premium ceramic pads' heat levels. (Something the previous mechanic should have advised me when replacing the pads, and something I should have thought of on my own as well.) Premium pads deserve matching rotors. Long story short, Ken asked me what i wanted to do regarding the brakes, as replacement rotors and pads on a 2008 Charger are not pocket change. I told him to replace both rotors and pads with quality replacements which he then ordered and installed. He took it for a test drive and worked the new brakes at different speeds to confirm that stopping power was restored and about 90 minutes later (and a few hundred lighter in the wallet), I was on my merry way. The cost was not unreasonable considering what I asked for as parts and the level of customer service was top notch. This shop will be around for a while but they will likely have a line of customers, so definitely make an appointment if you can. I got lucky and Ken was very obliging and understanding of my situation. An honest mechanic is good to find. read more

I've been going to Ken for my car and my husband's cars' needs for several months now and I just have to say that he's the only one I trust when it comes to car repairs or regular maintenance. He tells you exactly what you need to get done and doesn't overcharge you for them. He also offers to pick up your car if you don't have anyone to drive with you and your service will take a long time. It's difficult to find trusted mechanics these days but you can be sure that Ken will do a great job for you no matter how big or small it is! read more

It's so hard to find an honest mechanic. When my clutch went out I took it to a place closer to my home. They quoted me over $1000 more than what people on google had said it'd be. When I balked, I was told, "oh it's negotiable". But, they were so out of the ball park, I left in disgust. I then took my car in to Ken at Concord Auto, and he was initially hesitant, since I have a hybrid. But, after doing some research, he said no problem. He was upfront about the costs, and once he received all the parts, he had it fixed immediately. And, it was still $1000 less than the first quote I had gotten. Ken and his mechanics are great at what they do. They're honest and reliable, which is so rare these days. Now that I've found him, I won't go anywhere else. read more

Wow! I just had my car treated to the best spa day every and its working so well for me know. I love it thanks to Ken and his caring experts at Concord Auto Service. Ken was exceptional, and he took me home from the shop to drop off , and picked me up from Bart to go back . I only had to have my partner take me to bart once the whole time my car was in the shop. How convenient is that. Talk about putting the customer first. Ken is top notch! he really deserves 5 stars with a Triple AAA on the end. Thank you Ken. Happy New Year . Service 12/28/12. Looking forward to my next service, I don't have to worry about missing work, and the cost was reasonable. read more

After visiting Concord Auto Service, I was inspired to start a Yelp account. I usually go to a dealership for my car needs, but my friend convinced me to give this shop a chance. I dropped my car overnight and got a call from Ken, the owner, who said my engine mounts caused a leak in the intake valve. Once the parts arrived, they were replaced immediately. My first visit was pleasant, expedited and left as a satisfied customer. Since then, I've returned several times, with the same quality and professional service. Ken deals with customers personally and ensures each job is efficiently done. Give this full service shop a call to see if Ken and his crew can resolve your car problem today. read more

My husband normally fixes my car, but he won't touch ac issues with a ten foot pole. I know that ac can cost an arm and a leg to fix so I was not excited about having to find a professional mechanic to make my car cool again - but Yelp came to the rescue! I chose Concord Auto Service based on the amazing reviews, its proximity to my home & job, and the fact that Ken gave me the best quote for a diagnostic out of 7 mechanics (everyone else was about $50 more). I found every positive thing that other people mentioned here to be true. Ken was extremely professional, communicative, and easy to deal with. He really does give A+++ service at a reasonable price. I am so happy to have a mechanic I can trust for those times that my husband can't fix something. Thanks Yelp for steering me in the right direction! read more

Exceptionally kind people who do solid work at very fair prices and feel very honest about what you actually need. I felt very confident with their services and they were a pleasure to speak with. :) read more

I had my coil-over suspension system installed here. When I arrived to chat with Ken to get things started we had a look over at everything to make sure we knew what the job would be. Ken asked me various questions about how I wanted these installed. On hearing my answers he came up with a clear picture of what he thought I actually wanted and we discussed a bit. I put full trust in him to get things right and he hit the nail right on the head. Additionally, they give rides to and from bart and Ken noticed a noise coming from the front left of my car. He called me and let me know that he took a look and couldn't find the cause of this noise and that I could take a gamble and replace two parts to see if that helps. How many people would tell you that they don't know what the problem is for sure? Ken and his team are a genuine bunch of people. During our various exchanges while he was trying to understand the settings I wanted he said, "I just want you to be happy". That really made it clear to me that he cares about his work and making sure his customers are happy. I highly recommend these guys, I'll be coming here for other work I need done on my car. read more

Ken and his team at concord auto service are great! They are honest, reliable and hard working. I know that I can count on them to take care of my auto service needs! I wouldn't take my car anywhere else! They do a great oil change and also other maintenance services your car may need. read more

I bought a Groupon for oil changes to Concord Auto and was really glad I did. This is a small shop and they do good work. I was in and out pretty quickly and really had no complaints. Not much to say- good work, good people, happy customers. read more

It's been a while since I wrote a review for anyone, but this had to be done! With the new car, (well.... new/used) there's really no one else i absolutely trust to touch this car but Ken! Especially for big things like tune-ups including the more recent thing my clutch. It FINALLY went out. I tried to baby it for as long as I could, but it just didn't want to work for me anymore. I've gone to Ken plenty of times before for my oil changes so when my clutch went out, he was the only one I thought of bringing my car to. Ken is VERY knowledgeable, honest and his prices are better than anyone else's to boot! So, if that doesn't entice you to go to his shop and use his services for you auto's needs then I don't know what to tell you. If you want GREAT work and an HONEST opinion from someone about your vehicle, give Ken a call! I guarantee you will not be disappointed!!! :D read more

The one thing I like most about Concord Auto Service is that I trust them. So often with auto service you are sold things you do not need. Ken the owner of Concord Auto Service is honest, reliable and has integrity. Concord Auto also does a great job. I have always been pleased with the work he's done on my Corvette. If you need a good mechanic who you can trust, definitely call Concord Auto Service. read more

I saw all the great reviews on Yelp for Concord Auto Service. Believe, me they are all true. The service is great, they are trustworthy, and competitively priced. I highly recommend Ken and his team to anyone. They are great mechanics and an awesome business! read more

If it was possible, I would give Ken more than five stars. When my Grandfather passed, I decided to give the car to my cousin. He lives too far to drive the car home without a tune-up, so I offered to take it in and handle it here, my cousin only needed to arrange to pick up and pay for the tune-up. My cousin took two whole weeks to pick up the car, and Ken was communicative and way more understanding than I would have been. He is the absolute best, and I will continue to bring my car here as long as I live in the bay. I wish every mechanic and business owner was like Ken!! read more

Ken went out of his way to help me with my truck. He has earned my business and I will be taking all 3 of my vehicles to him in the future. Highest praise for his direction and customer service. read more

Best shop I've been to. Honest, reliable......... Ken is the best. Only place I'll take my vehicles!

I can't say enough good things about Ken and Concord Auto. A few months ago my wife and I brought our car in and as first timers at a mechanic were a little nervous about the process but Ken gave us a really great experience. From start to finish he was nothing but friendly and honest and also kept us in the loop with what needed to be done and how much everything was going to be. I definitely will be back if I need anything else in the future. Thanks ken! read more

5 stars, I take all my vehicles to Ken at Concord Auto Service. In fact, last week my water pump went out in my Buick. At first i thought it was the radiator but i found out it was the water pump, pow the next day i was back on the road driving with a new water pump in place. The price wasn't outrageous and the service was awesome. Thanks Ken. Nathan @ KB Carpet Cleaners. read more

Fast turnaround on a new fuel pump for my older GMC Sierra. Ken is friendly and knowledgeable, and his prices are reasonable. Happy to support this great local business! read more

Ken is easily one of the most trustworthy guys in the industry. You can count on him to be fair, honest and tell you how it is. My 2003 Mitsubishi Eclipse GTS has sat collecting dust for the past year. My clutch was fried, I knew Iit had some considerable damage from all those years and miles. She was long overdue for some major TLC. Man, did he treat her like it was his baby. He did her right. She hasn't been better. My car purrs, still has great pick up for a car with well over 220k miles. The suspension and steering is tighter and really handles well. As always I am impressed with the work they have done with my car, especially for a project such as this!! I had worked with Ken on a couple of other occasions and I have always been impressed with his demeanor and forthright discussion. He also has a fine staff working with him, always helpful and friendly! I trust him 100% with my cars!! read more

I called This location trying to get in quick for a service. Spoke with Robert on the phone, I inquired on appts and he said " when you want to come" ? So I ended up just coming in with no appt. I was in and out in a timely fashion, I was satisfied with the customers service as well. read more

We had bought a new Audi from them and the rear door did not function like the other three doors. We drove to Audi Concord from San Francisco, they immediately agreed to remedy the problem. They gave us a Audi Q5 loaner until our car is repaired. Whenever we go there, we get great service. Adrian in Sales and Aaron in Service are both very professional and get out of their way to assist customers. read more

As a single mom, i dont have the time or money to be bs'd by repair shops. Ive been duped by shop after shop. I recently spent 1200 dollars for absolutely nothing. Same problem existed and i ended up using all four of my AAA tows only to have nothing resolved. I rolled into this shop with a coolant leak and minor temp increase. The gentlemen helped me out with a bit of coolant to get me home and suggested i look into where the leak was coming from. I brought my car in a few days later and they fixed my leak and didnt gauge me. No more overheat smell. No more coolant dribbles. So then a week later.....im on the freeway and i suddenly lose power and all my dash lights came on. Panic set it. Onstar said get her to the shop asap. I knew just where to come to. I rolled back in to drop my car off and they even drove me to work! Within a day they called me back and let me know that they reset the codes but for some reason....the codes wont come back on even after a lot of test driving. Any other shop ive been to would have done (or claimed to have done) a bunch of costly unnecessary repairs. Not here. Not to mention...They didnt charge me a dime. I cant even express in words how grateful i am. No matter what u need done...this is the shop to bring your vehicle to. Good work. Good ppl. Great service. Thanks guys! Sincerely, Customer for life. read more
