I've never purchased a used car before, but I recently bought one for my 17-year-old son--a 2016 BMW M4. Since it's a high-performance vehicle, buying new wasn't an option for me, so I went the pre-owned route. About five days after the purchase, the car suddenly downshifted on its own and the engine malfunction light appeared on the console. After restarting the vehicle a few times, the issue didn't repeat, but given that it had only been less than a week since purchase, I reached out to the broker. They referred me to Contra Costa Auto Service, a shop they partner with and one that had previously serviced this vehicle. Although the issue didn't resurface during their inspection, the technicians took the time to thoroughly review the situation. They explained that it could have been caused by moisture buildup leading to a temporary rough idle. What impressed me most was their professional knowledge, their transparency, and their recommendation to keep the extended warranty for added peace of mind. My son and I left feeling reassured and confident, knowing we had been given honest guidance. I truly appreciate their expertise and professionalism, and I would gladly return to Contra Costa Auto if any future issues arise with the car. read more

Replaced alternator on my Mercedes, had to remove turbo lines to access alternator, added different coolant color than was in there, week later water pump went out, paid for that, week later I'm driving hours from my house and the alternator goes out that they just replaced. I wouldn't trust them to change my wiper blades, good luck. read more

Definitely recommend this shop for repairs, all the technicians are very knowledgeable and helpful, had my brakes done and couldn't be happier. read more

This shop was referred to me by a work associate who raves about their business practices. I took my 2016 CX-5 in to diagnose a new engine noise. What happened is a long story, but I agree with my friend: These folks have incredibly high standards for customer care. My Mazda CX-5 is a great vehicle and I'd buy another, --IF-- Concord Mazda's business practices was even HALF as good as CC Auto Service's. So I'm replacing my CX-5 with a Honda CR-V, and I will DEFINITELY go to Contra Costa Auto Service for future service work. I've already started referring friends to them. read more

Brake light on my car went out and I got pulled over for it in Walnut Creek. I needed to get it fixed quickly because I would be driving someone for my voluteer work in the afternoon, and would have to cancel on them if not repaired. I called Contra Costa Auto Service on a whim, and so glad I did. They were polite and inviting on the phone and the same in person. Angel helped me out and he was so nice and understanding. I took about 30 min of his time and he didn't charge me for it. I will definitely return for any additional work needed on my car. Highly recommend giving them a try. read more

I recently had a great experience after having car transmission issues. Brandon and Justin were so helpful!

I definitely recommend this place! My Mercedes had an issue the check engine light was on and they knocked it out the park! Great customer service to Brandon and Jessie they were really polite, helpful and professional and also patience while working with us. They got the car done in a timely manner, they test drove and rechecked everything to make sure our car drives smoothly. I couldn't be more pleased with the work and the price!

After discussing my car's issues at a local Cars&Coffee event, I was suggested to try out Contra Costa Auto Service. I was more than happy to give them a try based on my not so good experience with my local repair shop. Man, am I glad I did. From the beginning, Justin exhibited a professionalism with a side of honesty that is refreshing. My clutch was failing, he suggested a full replacement, which I didn't want to do initially. I ended up going with his suggestion. After completing repairs and test drive, they noticed that there was still a problem. They took it apart, found the issue, and notified me. I was skeptical thinking that here comes the dreaded add on charge(s). No, not the case. There was a broken part which did have to be replaced but no additional labor cost. They could have charged me additional labor for all of this but I only paid for the damaged part. They owned up to the fact that they didn't identify the damage initially. Took a couple of extra days but was totally worth it. Highly recommended and I will bring my car back should it become necessary. read more

Angel, Justin, Jesse, and the COCO Auto Service crew did a tremendous job on our 92 Yukon to replace its 33 year-old transmission - torque converter, replace the front disk brakes, reseal valve covers, oil pan, replace timing chain and reseal the front of the engine, and hand clean the underside of the truck. Besides their great work, was the excellent level of communication throughout the several day process (new tranny came from Jasper in the mid-west). Once the tranny arrived, all work was completed very promptly. The appointment started with a full assessment of the condition of the truck - with photos which Angel provided the assessment of each finding. Clear estimate was provided for each task and potential savings were identified for overlapping tasks. All three professionals knew the status of the work so a single phone call update was all that was needed. The shop is spotless, well equipped, and with several service slots. We were treated like family. COCO Auto Service has experts for most all car makes. Definitely will consider COCO Auto Service in the future. They will take care of your ride. Thank You read more

I called this place made an appointment based on a diagnostic another company did for me. Long story short they repaired what I requested and when that didn't fix my problem they called to let me know and get my approval on a complimentary inspection. They went way above and beyond my expectations. Definitely recommend this place and will always use this place very friendly and helpful staff. Thank you read more

Great service at a fair price. They were definitely lower than the dealership. If my other car has a problem, I'll go back to them.

I always take my FR-S to Neal and the Contra Costa Auto Service team because they know my type of car so well. During this latest service, they noticed an unexpected problem and had it fixed very quickly. they explained the reasons to me very carefully. Cheers and thanks CoCo !!! read more

Contra Costa Auto Service - Auto Repair Near Me - Concord, California

I brought my vehicle in, 18 Honda Accord 2.0T for Scheduled maintenance and these guys did a great job describing the process of what exactly was preformed. - Thank you :) read more

Contra Costa Auto Service: They are very honest and trust worthy business. Beyond good advice and fair prices they have a good turnaround time and will go to bat for their customers. I have had a couple issue with my 2011 Mini Cooper. The first issue they fixed at exactly half the price that Concord Mini quoted me ($800 rather than $1600). My most recent experience was even better. I brought my car in with another issue; Contra Costa Auto Service called me 30min later, explained the issue and informed me that this could be covered by an extended manufacturer's warranty. Contra Costa Auto Service went to bat for me, called the dealer for me and saw to it that honored the terms of the warranty after they tried to get out of it. Key takeaway: Contra Costa Auto Service has great customer service, it is a trustworthy business, they are effective and efficient. read more

The way this shop do business, Iam wondering why are they still in business.. I set an appointment online about 5 days in advance. they confirmed it and they again re confirmed it the day before my set appointment. When i get to their shop on time for my appointment, they told me they only have one technician and they cant do my car that day. Things happen with technicians but they did not even bother to call me to inform me to reset the appointment. They mess up with my schedule and wasted my time and the guy in front office looks like he didn't care.. read more

They have given me extremely helpful service and detailed reports before giving the car back. As a former mechanic myself I usually have a hard time dropping my car places for service. These guys make me extremely comfortable with someone else working on my car. read more

This review is a couple weeks late, i went to the shop for some noises my car was making. They drove it and looked up the hood to find a issue with my transmission. They worked hard and consistently with my warranty to get it replaced. The process was gruelling between the warranty inspector and the approval but they stayed on it. Told me not worry. They lifted that burden off. They let me know through the whole process of when they ordered. When they got the part and the second it was complete so i could get my baby back. They even called the rental company to explain what was going on about time frame i might need the rental. Which helped. I appreciate these guys. AWESOME communication and customer service. Ever need a good shop? This is the place. Thank you! read more

Great service with fair and reasonable pricing

I thought I found a shop for BMW fanatics, but was sadly mistaken. They came highly recommended by the BMW forums too. I brought my beloved ZHP for a small service. I was less than satisfied. My car was filthy afterwards! The steering wheel (alcantara cloth) was all grimy. My hands were black by the time I drove home. They need to do a better job of keeping their hands clean when inside a customers car! Use disposable gloves for crying out loud! Ugh. Anyways, still in search of a good BMW shop...I miss my old shop. read more

I hadn't known about this shop before the new owner bought it. But Adrian has been servicing ALL my family's vehicles (5 cars and one motorcycle) for about 8 years. When he told me he now owned a shop right here in Concord, well, that's where my 525i just went for minor repairs, service and smog. As always, first rate service. On time, on budget, wallet-friendly pricing. Expect nothing but the best from Adrian and any shop he owns. What else can I say? Check Yelp reviews after he took over the shop. Once you find someone you trust to take care of your vehicles, life becomes easier. Now I have more time to spend Yelping food reviews, cause I don't worry about getting cars fixed. Winning! read more

The whole team is great. Alex is very informative, and Communicated with me during the entire process. They are very quick, honest, and affordable. I took my car in on Tuesday morning at 8:30 and got my car back Wednesday at 2 PM. I would definitely recommend this Contra Costa auto service to anyone read more

I had a bad experience at this shop today. The first time I come there so I want to ask questions. So after some teeth were pulled I had some answers. Customer service was lacking. I have had the same Mercedes mechanic for over 20+ years so I was a little nervous. I want to find a permanent place to go to and have trust. My car was pulled in. I go outside to see as much as I can. The mechanic walks over and starts to change the oil. I was watching a few minutes and the next minute my car view is blocked 80%. They pulled in a car right behind mine. I just moved where I could still get a look. The car was moved 15 minutes later. I noticed that they are starting to look around. A few parts were taken off the car. This car was purchased 8 days ago. It was inspected from the dealer and they walked me thru the car. (the car is still under Warranty) This dealer did forget to change the oil which they told me that they would send me a check and I said I would get it done. I was shown the hoses as I watched them pull on hoses and other misc things. I seen the bottom of the car also. So now my car is finished at CCAS. I see mechanics gathered around my car and I'm thinking here we go. So I have a leak between the transmission engine area, I also am told I need new shocks they are also leaking and a hose that was torn away from both ends of connection. They told me the car had a rodent and he did it. So, I'm not buying it. I grab the hose and try to push it back in and it gets bent and wrinkled. This is not what the hose looked like. 4 people seen the engine in the last 8 days including a mechanic at a Concord shop and no one made a comment that there was something wrong with anything including my hoses. I will get the leak looked at under the car, shocks and replace the hose. $ It hopefully will be covered by the warranty. Oh 1 more thing as I was leaving I asked that the mechanic to show me the oil and where it was at on the dipstick. I was told that my car did not have a dipstick.. My car was checked yesterday and the guy pulled out what looked like a magical dipstick that had oil on it. He said your oil needed to be changed, but the level was fine. Okay, So Mr. Mechanic why do you not know that the car has a dipstick.?? ---BEWARE I do have to say that I did talk to Adrian (owner) and he seemed like a great guy. That's why I added a star. read more

Contra Costa Auto Service - Auto Repair Near Me - Concord, California

I have brought vehicles here for almost 20 years. Reasonable, fair, knowledgeable, reliable, friendly. Like family, they go above and beyond to assure a quality experience and objective assessments based on their years of wrenching on many different makes and models. They have served and repaired for me - Mazdas, Subarus and MINIs - They stand behind their work and provide sound advice if you are looking to upgrade components or to help deciding whether it is time to look for another car. read more

I brought my Trans Am in to have the gears replaced a couple of years ago and they incompetently reconnected my brakes and could have killed me, or worse, I could have killed somebody else. I got almost all the way home after picking my car up and the rear brake line came off (because it clearly wasn't put back on correctly). I'm thankful that it popped off while I was at a slow speed and nearing my turn and nobody was hurt. I then limped it to my house. I had to get the car towed back to the shop where they had to reconnect the brakes and polish up the rear wheel where the brake fluid got on it. Luckily no real issue with it eating away the clear coat. Either way, I will never bring another car to this shop. Poor QC done on the work and I also failed to mention that the gears were not installed correctly. The car howls like a coon dog when you drive it down the road. Don't waste your money on this place. I'd give them no stars if it let me. read more

Took my car to get look at and wasn't please with the response of the Advisor when I received the call regarding the issue with my car. For one thing where all in a pandemic so let's try to help someone and to criticized every issues with my car, is like he was happy everything looked bad in my car I don't get it. At least he could've showed me the issues in my car everything was verbal and unprofessional comments towards my car. Well the good thing is I will never have go to there again. read more

My first time here to service my car. They gave great service! I will return in the future all of my maintenance.

Contra Costa Auto Service is always amazing but never surprising, except in the best ways. When my girlfriend's car recently needed a repair, I suggested Contra Costa Auto Service. She had heard me speak favorably of them before and decided to take a chance with them rather than go to the dealership. She was amazed by the team at Contra Costa Auto Service and pleasantly surprised. Even though her repair had been scheduled somewhat on the fly, Alex, Dennis, Frank, Dan and Adrian made sure she was accommodated the next day. Under their supervision and skilled hands, the needed repair was affected rapidly for less than half of what the dealer wanted to charge. The dealer had also tried to insist she needed a new part, which in fact was not needed. As always, the work was done at an unbeatable price with no nasty surprises, up-sales or markups: just plain, old-fashioned, sound mechanical know-how by classically trained artists who can effortlessly wield the most sophisticated new equipment and innovative techniques. Contra Costa Auto Repair went above and beyond the call with solid, honest service, a smile, and welcomed my girlfriend into the family. In my experience, the customer is always treated like family at Contra Costa Auto Service, and as I've written before, whether routine maintenance or the most involved repairs, Contra Costa Auto Service delivers first rate work with excellence, in a timely manner, and at unbeatable prices. If you want to bring your vehicle to a place where you don't need to fret about the caliber of the work or the bill, I recommend checking out Contra Costa Auto Service. This is customer service the way it used to be and automotive care you can trust. Family and friends -and now my girlfriend--are always satisfied when they "discover" Contra Costa Auto Service. I think you'll be satisfied, too. Check 'em out. Join the Contra Costa Auto Service family. read more

Love this place! Good service and good people. Highly recommend! They will take good care of you and go out of their way to help you. The biggest thing is the honesty and transparency.

Highly recommend!! read more
