Clayton Auto Service

My Mazda has over 250,000 miles and has only recently begun to need some minor repairs. I have entrusted Clayton Auto Service to do the repairs. They are always kind, efficient, personable and reliable. I had a frank talk with Irfan the owner regarding hanging on to the car at this stage of its age/​mileage, and he encouraged me to repair what was needed as otherwise, it’s in pretty good shape. Thank you, Irfan, Steve and Armando for giving me and my car great service!

I’m so grateful to these guys here. They got the job done. Excellent customer service.

Same issue as another reviewer. They lied. Came in for an oil change and general car check up as I was planning to go on a road trip. They told me my catalytic converter was damaged and would cost around $ 1000 to get fixed and wouldn’t pass smog without it. My dad suggested I try to get it smogged anyway since my registration was due, and guess what! IT PASSED! And it came with a complete breakdown on paper, and it shows «Catalytic Converter: PASS» !
and another mechanic friend of mine said that my oil was so dirty they must not have actually changed the oil because they got distracted by the «catalytic converter issue» but didn’t seem to notice my MOTOR WAS LOOSE. $ 60 for nothing. Females be aware, they will rip you off.

Great and quick service! The guy helping me out even gave me a business card for a nearby auto shop! I’ll definitely be back!

Cheap and honest. I thought I had a lot more wrong with the car and was ready to pay but he told me it was all good! They forgot to do the oil change but when he found out they were literally running to change my oil ! It’s hard to find honest hard working mechanics.

Brought my 2006 mustang in for a smog check in March. They said it would not pass and wanted to charge me $ 1,000 to fix a pipe so that it would pass. Brought the car to a reputable dealer in Walnut Creek, who said nothing was wrong with the car. Good thing I went for a second opinion. Could have been ripped off for $ 1,000 by CAS. And to-​boot, they charged me the $ 60 for the smog check they said didn’t pass! Shouldn’t try to rip off ladies! Never going there again!!! Beware…

Took my son’s older Saab to get some repairs done. Price was good and service was great. Everyone was very helpful and friendly. Also got great tips about the car that i did not know.

I’ve taken my old Altima here for a few things over the past couple years and have always gotten fast, friendly service. I just got a new Santa Fe a month ago, and I already got a flat tire (it had a screw embedded in it). I brought it to Clayton Auto service to be repaired and I got the same fast friendly service. I highly recommend them, and will always go to them for any car repairs we need!

Did a great job getting us in for a leaking tire. Very friendly just thought it was a little expensive, but who knows its been a long time since I’ve had a nail taken out

Came here for two visits. We came in to get smogged and get a tire pressure monitor sensor replaced. Both visits were very smooth. Irfan and his crew were friendly, transparent and got the job done. They are a breath of fresh air compared to most dealership service experiences where you will be overcharged for any type of service.

Irfan is super honest. I been using him for 10+ years! Super reliable mechanic lowest prices. No funny business guaranteed.

Clayton Auto Service is the place I go whenever there’s a problem with my car. I know that Irfan and his knowledgable mechanics always provide quality service at an affordable price. I will always highly recommend their services! Highly professional and reliable.

TL;DR: Incompetent customer service, lied about the parts they put in my vehicle, took 5 hours to do what was supposed to be one simple job.
My most recent trip here, I came in to get a radiator flush as my coolant level had been low and I topped off with too much water. Been running like that for a few weeks and wanted to get some proper fluid in there.
Guy behind the counter says he wants to check for leaks, to make sure that there’s no issue. Fine, go ahead.
Says they do a pressure test, find out the water leak is coming from the water pump, and supposedly a temp sensor and gasket need to be replaced. I asked to see the parts, and in all honesty there appeared to be nothing wrong with them. No visible wear or tear, everything moving as it should be. He claimed there was some issue with the bearings in it, which is why it rattled, even though you couldn’t hear any such noise, nor had I noticed it driving before.
The second car I ever owned, the water pump went bad, the whole engine seized and I ended up having to junk the car. This still fresh in my mind, I figure even though this is way more than I had anticipated spending, I didn’t really want to take the chance. Car is 13 years old, so maybe he’s right. He says they’ll use OEM Manufacturer parts to replace and repair, so fine by me.
Calls to warehouse to get parts delivered, supposedly they are on there way and should be at the shop inside half an hour. Half hour comes and goes, then an hour, still no parts. Another half hour, and I finally tell them to call back and find out what the delay is. Apparently delivery guy didn’t come into work, so the parts never would have shown up had I not thought to ask them to call back. Apparently they were content to leave me sitting there the whole afternoon.
They send off one of their guys to pick up the parts, come back, and finally get to work. About an hour after that (about 5 hours into my sitting at the damn shop), they are finally done, and it comes time to settle up the bill.
The gasket is no longer listed on the parts list, nor the temp sensor; neither were replaced. Both parts are removed from the bill, and I’m looking to see the parts cost have gone down, but suddenly the water pump is 25 dollars more expensive. And even though they did less labor replacing the parts, the cost of that is still the same.
After I get home, my GF, who was the manager of a parts department for a large dealership looks over the receipt, and informs me that the part number listed is NOT in fact a Ford OEM part, just to top it all off. Confirmed this by calling a Ford Dealership and getting the actual part number from them.
I can’t put these guys on blast enough. I will probably go back and file a complaint with the owner, who seemed like a nice guy the first time I brought my car there for a smog.

Don’t go there, theyll rip you off. they charge for smog check twice more than other places.
I wont trust them with prices and work done.
Make sure check the charges with other places and shop around before you decide to go there, I suggest not choose them at all.

Very Helpful. Affordable rates. The guys were really nice. Samir helped me and even gave me a 10 dollar discount for my smog check. Will definitely come back again :)

I just had my oil changed and smog check completed from Clayton Auto Service. I was a walk-​in and I was out within 30 minutes. The owner, Irfan, was very pleasant to work with. I highly recommend Clayton Auto Service.

Do not go here, Went for smog test, they made me pay $ 250 for diagnostics and could not even make my car pass had to go elsewhere and they passed same day. Be aware the owner is very pushy and abrupt and does not take no for an answer.

Made the long trip back to the Bay and wouldn’t you know it? The infamous CHECK ENGINE LIGHT comes on. Honestly… I hate that thing. It’s like a siren that goes off that gives you know NO information on what’s wrong. Oxygen sensor? Catalytic converter? I wish cars would give more helpful warming info without the the need for plugging in the diagnostic sensor port. But I digress.
Armando at Clayton Auto service was very nice and helpful. Showed me the code right there and said they would diagnose what’s wrong, telling me the labor rate and saying that it would cost more for parts only if it was necessary. In the end the engine was running lean because the fuel lines were losing vacuum pressure. They cleaned my mass flow sensor while they were at it. In the end I they were relatively quick and transparent. Can’t ask for more than that from an auto shop!

I came right when they opened on a Saturday at 8:30 am and there was no one in front of me. All I needed was an oil change and Samir said that it would take 1 hour. I thought that was a bit long for a simple oil change when they have 4 people working on cars. Usually, it takes thirty minutes to do a oil change at most.
The reason was because they decide to work on cars that are already in the shop from night prior instead of working on a customer’s car that comes in right when they open for business. I’ve never seen a auto shop that is so inefficient. Instead of having one of the guys do a oil change job first and get that out. They instead choose to work on other people’s cars that aren’t even waiting for their car.
So a supposedly 1 hour oil change takes 2.5 hours due to inefficiency and lack of customer’s respect. I obviously will not be bringing my business back here.

this is the place I’ll take my cars when I need a smog or other work
Great job
Thanks
