I came in for a cylinder 5 misfire and told them that I already replaced spark plugs and ignition coil and they told me it would be an $80 diagnostic. I asked them to run compression test and check fuel injectors since that would be the next step after what I had already done.They call me back an hour later saying that I didnt change spark plugs because cylinder 5 still had oem plugs and not NGK. THEY HAD CHECKED THE WRONG CYLINDER. I explained the one they checked was not cylinder 5, it was 4 and they went back to check the correct one. almost 6 hours later they call back again saying that the spark plugs and ignition coils were fine so it was something else that they couldnt fix. I KNOW THE COILS AND PLUGS WERE FINE. I TOLD THEM I REPLACED THEM JUST HOURS BEFORE. They forced me to still pay the $80 diagnostic even though all they ended up doing was checking the work I had already performed. No compression test, no electric test, no sensor test, no fuel injector test. They only checked the things I had told them many times I had already replaced. They scammed me into getting their diagnostic knowing full well that if it wasnt spark plugs or ignition coils, they couldnt do anything else. (which obviously it wasnt because I told them over and over again that I already replaced those). That was the entire point of me bringing it to a mechanic.These people have very limited mechanical skill. Do not go to them for any kind of engine repair.They told me when I picked up the car that normally they dont charge for diagnostic without repair but they would charge me because of the amount of time they spent on my car. Really? It took them 7 hours to check the cylinder 5 spark plug and coil? Unbelievable. These are not mechanics, they are scammers.When I was in their waiting room, they were even arguing with another customer because they stripped his oil pan drain plug, and yet were making him pay for the replacement. That should have been a red flag for me, but lesson learned.

These guys are awesome. I have gotten same day repairs at a reasonable price with a family feel. It feels like your neighborhood garage! Totally recommend!

Best auto repair I ever been to....fairest price best honest work .i highly recommend.......And the staff is so people friendly.

The Best. Honest work, Ive been a loyal customer for years. Ive moved 20 miles away and i still got to Clayton Quality. Its in their name.

This is my favorite place to get my oil changed they have tons of other services and are exceedingly friendly and when I google the thing they are talking about they are asking for a very reasonable price every time. I would put my trust in their diagnosis and work with them if you have concerns about price. My father was a loyal customer and went to them for years. I promise this is the best place for auto questions and services.

Not to bad. they can do simple jobs, but nothing serious.

Great place! The team is always polite, friendly, and helpful. They have done everything from rebuild my engine to change my oil and headlights. I have found them to be trustworthy and fair. They also do a great job at checking a car before you buy it and giving great advice. Highly recommended.

Amazing people and amazing service.

Clayton Quality Auto service is my go to automotive repair place. Their always friendly, prices are fair and never try to sell you something you dont need. Thanks for taking care of our cars and trucks.

Very nice service .

Best Mechanics in town. They will save you a a pot of gold!

This is my second time coming here for an oil change as I recently moved to Concord. The employees here are wonderful. They were all very polite and helpful. I’ve now got my mother bringing her car in as well because of the great service I received. Thank you to the entire team. Your dedication to customer service is appreciated.

I just had my car there for a oil change . I had my own oil and filter. They supposed to fill with 6 quarts , but they used only 5. It’s clear , they didn’t drain completely the old oil. Big time crooks...

Though busy, they were able to squeeze me in to work on a problem with my car starting. I was without my car for less than a day. Thank you Clayton Quality Auto team!

MOST DEFINITELY RECOMMEND this to EVERYbody!! Ive been coming to this place for 3years now and they never fail to give me the best service anybody would ask for. Theres a local shop walking distance from my house but I prefer going the distance to come here. Very honest. Very fast. Excellent customer service. Overall A+++++++

My husband and I traveled from Washington State to Concord to visit our families. Our brakes felt spongy and we were leaving town on Monday, so we check out this place on Sunday. These guys know their business and ordered a major part for us and after a delivery delay we were on the road home by Tuesday morning. We had no problems on the road and our brakes are perfect. You guys rock!!! Thank you so very much for making us feel like family and making us feel safe again.

Good

These guys are great. Always able to resolve whatever issue that arises with your car. Pricing is reasonable. Nguyen is very helpful. Very thankful they are in the neighborhood.

Not cool to carge a singel mother for things that arent even wront with my suv and finding out that they disconected a hose im pretty sure they would of known if it was a hose or not

Been going to them for couple years already recently since my check engine light came on spent abought 900 left light turns late on down the road charged me again for a diagnostic and know I need a evap first the price was 500 after when we said ok after they wrote on paper it would be a 500 dollars later come out to be 1500 took my car to some one else and he does a quick check if the car inspects it runs a scan he said yeah that is your problem same code he digs around and finds that one of tge hoses to that park was disconnected from were its attached to

I brought my car here ones to check the breaks and change oil. Met Robert shortly, he seemed friendly and reasonable. I left my car in this shop in the morning and came back after work at the end of the day. The job was done fine, I had no complaints. I will probably go back to this shop next time around when I need new breaks again.

The cashier is very rude and no good service for the customer,

Mike and his guys are definitely the best car shop in Concord!They are a real professionals, honest and the main reason I will highly recommend to any one to use there services is that they are straight forward with everything.Thank you guys for been wonderful I definitely recommend this business for any car repair!

I have been going there for years, take all my cars, kids cars, and recommending them for years, until now. Different people behind the counter, brought my car in for an inspection and was told I needed to replace all my brakes and rotors, took it somewhere else for second opinion and was told brakes were fine. I dont recommend them anymore. What a shame Clayton Quality Auto.

Decided to give Clayton Quality Auto Service a try after reading all the positive reviews and so glad we did! Our 2007 Veracruz had a check engine light on and was misfiring. Called and talked to Nguyen who was very friendly on the phone and said we could have it towed there right away and theyd take a look at it. As soon as I arrived I was greeted by Mike the owner who quickly diagnosed the problem and really took the time to educate me on what was going on with the car and was very upfront about the potential costs. The repairs were completed in a timely manner and the prices were reasonable.About a week later we brought our 2008 Honda Civic in for some repairs that the dealership had previously said we needed but seemed over-priced so we had put them off. After Mike checked out the car, the price he quoted us was WAY lower than the dealerships and some of the services werent even necessary, apparently they were just trying to up-sell us. So glad to have a found a mechanic we can trust! Mike really cares about his customers and truly has their best interests in mind. We have been so well taken care of at Clayton Quality Auto, from now on we wont be taking our cars anywhere else!

As a man trying to save myself a dime here and there, I did my own brakes. With 3 wheels done I started the fourth and well the caliper was so rusted and the bolts to it were completely stripped and seized. These professional people took great care of me by removing those bolts for just the price of an oil change. IF YOU WANT QUALITY and you NEED to save a penny, you would be making a mistake by not coming here. These guys are very friendly and the owner runs a damn fine shop. A gentleman by the name of Bobby really helped me out when I was in a jam. Thanks again guys !

Best In Town, Maybe Best In Contra Costa County, But To Each His Own.. And The Owner Is A Hottie...

DO NOT take ypu vehicle here. It took two and a half days to swap a starter, which they said was not the prpblem after they did a diagnostic. Then when I went to start my vehicle, it did not start. It needed a jump, which the mechanic seemed to regard as normal. Had work done anout a year ago and was pleased. This is the second time since and the quality, competence and management seems to be sliding fown hill fast.

These mechanics changed the O2 sensors on my Subaru. After picking it up, there was a tapping noise so took it back thinking something was loose. Well they spent time looking at it and diagnosed free of charge the transmission going out. So that was great service.

Great service. Always take my cars to get oil changes, breaks, engine repairs, tune ups, tires, battery replacement even helped with catalytic converters replacement, fuel pump what can I say one stop shop. Tell them I sent you. Please thanks

These guys are great. Pricing is reasonable. Very lucky to have them in the neighborhood. Highly recommend.

Mike and his team are definitely the most knowledgeable people when it comes to cars. I had a bad AC sensor on my ford fusion and they took care of it after thoroughly checking out other components that could be bad. If you happen to get your car fixed by Win, Amin or Imran, you should be very happy. They are definitely the best mechanics one could ask for.I suggest everyone to check this place out.

Great and honest people completed my tune up and brakes on my f150 fast. Highly recommend!!

Excellent service and job well done.

Thank you to Nguyen, I hope I spelled it correct. Was a little pricy for a tune up on my trail blazer, However, they were open on a Sunday and most places are not. This guy was up front polite, and honest. We had a good conversation while my vehicle was being worked on. The estimated time I would get my car back took longer than expected. Not surprised because it was Sunday so staff was short. Unlike most businesses, Nguyen apologized to me and made it right. Will not disclose what took place. My point is, there , people understand other peoples situations and are caring people. I recommend Clayton auto service . 100 percent is to be determined since I just got my vehicle back and havnt drove it much. As far as honesty and good people, thumbs up. Update in 30 days or so.

Horrible Service! Told they had Experts that could fix anything. Kept my car for 3 weeks before Christmas. Unable to fix car. Charged $1400 plus! Now without a car!

I wouldnt trust my vehicles with anyone else. They truly care about their customers. Best prices and service in the east bay. Dont bother looking anywhere else!

Theres a sign in the shop that says quality aint cheap and cheap aint quality, well they certainly werent cheap and this caliper bolt replacement certainly wasnt quality. This took them three days, I honestly wish they had just told me they did a bad rethread on the bolt so I knew it would be a problem before I went to change my brakes, but then I might have had an issue with the few hundred they charged. Thanks guys for turning a 20 minute pad replacement into a ruined weekend and a logistic hell on Monday.

Ive gone here many times. At first they seemed good, then I got a battery replaced and a couple months later they had to give me another one because the battery went out. I went back again to see why my car was over heating and they looked at the car for 5 mins and told me I had to get a new cooling fan and that it would cost $550. I left and did some research and found out they were overcharging for the parts and a job they claimed would take 3+ hours only took 40 mins. So I will definitely not be back, they seem nice but Im sure they have ripped others off like this.

So I have read some of the negative reviews and that is just not reflective of this place. Im not sure of the context of the incidents as well but I started servicing all my 5 vehicles as well as 5 RVs and they have been very honest with me and privided some of the best service Ive ever experienced.Mike and Hasia who are the newer owners have been amazing. Ive seen them go out of their way for me and many other customers every time Im there.Ive also seen some of those customers who like to cause problems and even fabricate things still get treated professionally and with respect.I am sorry for the few that have had an issueBut I can tell you Mike and Hasia will truly treat you right.I have to travel over the bridge from Benicia each time to get all my vehicle service done and its worth it.They work extremely hard to complete the work timely and they do a great job and are honest.I even started to have them do my tires on some of my vehicles.I know sometimes we have rough days but knowing these people and watching how they have treated me and so many others now for 4 yrs and counting and they treat us like family which is hard to find.I recommend them to anyone looking for an honest straight forward mechanic.Thanks Mike and Hasia for being so wonderful!!

This is the best place to fix your car! When i have a problem with my car again i will totally come back here again!

These guys are crooks!They charged me $60 extra to remove a cover that doesnt even exist!Stay away from this crime hole!

Friendly fast and price was good.

Awful service and unprofessional management and they will definitely over charged you as they over charged me.

Worst service ever unprofetional and inconsiderate about people time. They will over charge you just to take you money as well. Avoid at all cost 4 people complaint about having us waiting for 40 min than told us to come back the next day . They charge us for diagnostic without even fixing out car.

Great service excellent service

Great work and services

Very friendly and fast
