I will ALWAYS use this place and so will my family. They are honest with the customers budget in mind. My daughter needed 2 new tires, not 4, as suggested by a different company. She also had her oil changed and we not not sold new filters or additional services. They said no other services were necessary at this time. WHAT?!! I feel safe sending my daughter to Big O without me or my husband overseeing everything. What a great group of guys. read more

Went for an oil change- was there for nearly three hours?!! Luckily I had auto work done elsewhere the same week because they identified there was no oil in my car. This shop, in fact, did nothing to my car after wasting hours of my day there for a simple oil change service. They had me come back in and actually performed the service that they were originally supposed to, but at the expense of my time and potential damage to my vehicle. Would never go back or recommend this shop. read more

I had a insulting experience there and I am currently trying to get a meeting with the owner Edward.

Went in to get new tires on my Mercedes. All my lug nuts were there when I brought it in. They called when the car was done saying I'm missing two lug nuts. Didn't want to argue but they were later found In between the rotor and hub when a grinding noise was heard. Not sure how they got in there but very shady. Never going back!!! Wish I could give negative stars. read more

First time here In for a scheduled alignment Charged by the warranty In my humble opinion I felt like if you did it right then a warranty would t be necessary Anyway, in and out in about 39 min which I do like read more

Great place to get an oil change. Easy to make an appointment. Juan was totally friendly ,helpful, professional and understanding when he told me they no longer accepted Groupon coupons he arranged to do the oil change anyway since I was a returning customer. They easily and quickly did the premium change and had my car ready in no time. I highly recommend them for oil changes and will return again and rate them A+ read more

These are my guys. Great crew, positive attitudes all around, honest hardworking guys. I always go to them for all my regular maintenance, and whenever I've had a problem. I drive a lot more than average, no exaggeration probably three times more than average, 100K just in the last three years. They've kept me going. I go to them for all the big stuff, and sometimes they've cut me a break on smaller things like a fluids top up. I've had all sorts of services done, brakes, lights, a random throttle body issue... 150K mile service, trans fluid flush... etc etc. My battery was dying the other day, the car had a weak start, I only had a couple days off and i was worried about being able to get to work when I was due back. I'm flexible I was able to come back next day but they fit me in and got me taken care of. I do try to take advantage of their knowledge, experience, and enjoy picking their brains a little when I go in. I never have to worry about them trying to take advantage of me. I learn a little something new from them every time that helps me become a better car owner. Occasionally I go to the Petaluma location if it's inconvenient for me to get to Seb and they're great too, in my experience. But this is my preferred location. Thank you Sebastopol Big O team for taking such good care. You guys are the best. read more

Nice service people! They were courteous and efficient. Easy to find and lots of parking! read more

I recently had a 5 star experience with Big-O on a CarMax warranty related repair. The technician discovered and repaired an issue that could have been a problem down the line, there was a little confusion on whether the item was covered as the company that provides the extended warranty company initially rejected the claim. But, Ywaldo & Chris M. patiently sorted it out with the CarMax team and the repairs were ultimately covered by CarMax. Very appreciative of Big O's 5 star service, and CarMax proving the worth of their Warranties. read more

Super knowledgeable , friendly,kind and courteous. Ron being my contact thru out . Went above and beyond helping me with my car :) They took my car in right away as the battery had died and I needed to be towed in. And got me on the road quickly. Definitely will be getting my future oil changes here as well ! read more

The Sebastopol Big O Tires is a great auto shop and I definitely recommend this location. I've had several cars under their care for over 10 years at this location, and they have always done excellent work, from oil changes to tires to more complicated repairs. They are honest, fair priced and reliable. Thank you Sebastopol Big O Tires! read more

Quick and friendly service. I came in for a bi annually preventative maintenance on my 2016 Corolla while I was in the area. They took me in as a walk in and I felt like the guy handling my maintenance knew what he was doing. This will be my go to if I'm ever back in the area. read more

I got a flat tire/blowout on 101 on a trip to Sebastopol for an all-day workshop. I made it to the BigO on my spare over lunchtime and Ywaldo was able to immediately get my tire ordered to take care of me on the same day. He even went above and beyond and drove me back to the workshop so I wouldn't miss a beat. They were able to wrap it up by the time my workshop ended. Ron was also great on taking care of checking me out at the end of the day, even when I arrived after their closing time. Overall, a truly awesome experience - BigO really knows how to deliver exceptional service!! read more

I love Big O Tires in Sebastopol. As a senior female, knowing very little about vehicles they gained my trust a few months ago when I needed new brakes. Ron Jensen explained what needed to be done in language that I could understand which I appreciated. Last Friday it came to my attention that I needed an alignment & new shocks so I contacted Big O Tires and spoke with Ywaldo Gascue. We continued our conversation via text on Saturday evening & Sunday afternoon. He explained what needed to be done & ordered the parts so that I could be taken care of first thing Monday morning. I was so impressed that Ywaldo spent his personal time off, & being out of town to make sure I was taken care of. He treated me as if I was his one & only customer, like a VIP. I'm a customer for life. Big O Tires in Sebastopol is extremely fortunate to have Ron & Ywaldo on their team! read more

Do NOT go to this place of business if you value your money and want your car fixed correctly. They totally ripped me off and the owner is hiding from me. I returned two defective alternators and my car didn't even need one! they left tires right in front of the door and I fell over them and got banged up and yet I remained calm and reasonable after all of this. Then after paying 1300 for work and parts I did not need I kindly asked for a refund of the second defective alternator and the owner went dark. they are awful! Beware. read more

The service is very good, friendly people. Good prices. They can help me with the thinks I need read more

5 Stars I can't say enough good things about Big O Tires in Sebastopol! I brought in my lowered Tesla after pulling out of a parking spot and catching the cement parking block, which pulled the belly pan out from under my car. I had first gone to Pep Boys since they were closer to where it happened, but after 25 minutes, they told me they didn't have the lift to handle my car. I usually go to the Big O Tires in Novato, which is always amazing, so I called the Sebastopol location. They assured me they had the lift for my lowered car and could help. I drove in today, and they were incredibly fast--reattaching the belly pan in just 15 minutes! Everyone there was so helpful and friendly. As a woman, going into a car repair shop can sometimes feel intimidating, but I felt completely taken care of here. Thank you, Big O Tires Sebastopol, for the outstanding service! You've earned a loyal customer! read more

I have been going to big O in Sebastopol for years. Their Pricing is fair and service is good! Edward does a good job of hiring talented techs good managers. I went by there recently because I could not find a wrench small enough to remove one of the nuts used on the custom rims of my Jeep. They were able to help me out no problem! The mechanic and Ywaldo went above and beyond to help out and found a very thin 3/4 socket to do the job! And did it no charge! Thank you guys! James Matthies Sebastopol CA. read more

Bought a groupon online for full synthetic oil change. The price was $63. Of course, have the car being worked on and they tell me the cost is actually an addition $23. Groupon only pays for 5 quarts not 6 & "additonal fee's apply" for disposal of the oil. Feels like deceptive marketing on the part of Big O and Groupon. Given that ALL vehicles will incur these "additional charges", why not have the price on Groupon actually show $86 for a oil change? read more

So kind and helpful when I was having a problem with the oil in my car. They went above and beyond.

Great friendly service and fast. They fixed a flat. Gave advise on tires but were not pushy in sales. read more

I went in for an oil change with a group on. Their regular price is around $100. My group on was for about $64 but then I was charged about $28 when I got there. How is that a savings? Why not include standard fees in the Groupon? Then I get my car back and several things started going wrong. First, 5 miles down the road the tire light goes on. Thankfully I reset it and it hasn't come back on. A few days later my car had issues starting. Again, I'm super lucky that hasn't continued. What has been ongoing is my gas meter is no longer working and the meter that makes the gas pump shut off when the tank is full is not working as well. I'm a single mom. I sought out a group on for a reason, only to have them charge me nearly full price in a round about way and return my car broken. read more

Edward was a huge help and made the process super easy. It was a great experience that I was originally nervous about but he made it a good time. Left with no Questions or concerns. Will come back if needed. read more

Can I give it less than a half of a star? I think so. What happened. How could such a professional automotive shop turn into such an incredible mess in just over a year. On 12/13/2023 Marvin Reno and Javier Garcia excellent Service. ., then under Gavin Bright, all service went completely downhill. Poor customer service, multiple visits for the same issue, over and over again. Oil light on. Gasket on oil pan not secured. Bad customer service I now have a great mechanic. Golden Gear Automotive. Still would use Big O Tires. Just never this one unless there was a service change, as far as office management and service read more

I have been going to this Big O for years and years and I had always had a wonderful experience. They used to be awesome and always helped me out when I needed a good deal on tires. However in the past year or so it's really gone down hill. I've had them trying to sell me services I don't need, thinking I just won't notice on my bill. On top of that my recent oil change they lost a screw to my skid pan, resulting in it scraping the road while I was driving. When I went back they said they had fixed it, however when I went to a different place for an oil change they told me it hadn't been fixed just shoved back up there. All they had to do was replace one screw... Now the skid pan is damaged and I will have to buy a new one. Unfortunately won't be using Big O In Sebastopol anymore. read more

I have had especially great service at Big O for a number of years. Have bought ties and had oil service for years, always professional, respectful and kind fellows. At least three times I have stopped by with an issue and they have helped evaluate and fix an issue on the spot. Just this week I had a surprise problem on Friday afternoon and the folks fixed it over the next 3 hrs, including overtime so I could be ready for along drive the next day. Ethan in particular navigated the evaluation, found the parts and communicated with me. The hands on mechanics are great and Ethan was especially helpful. Cant say enough positive read more

We are a long way from home. Ripped up the bottom of our car going up our daughter's ranch road. Stupid us. Big O got our Honda parts right away and at good price. They let me go through car's underside for damage assessment. All the staff were honestly helpful and liked helping. Sounds bad but hope to never see them again. But if I am in this area again and need saving I will. read more

I scheduled an oil change. Staff were courteous and knowledgeable. Did take about an hour. All went well.

After getting an oil change they gave me a bid for $3,384 for front end work including tie rods, control arms etc, transmission fluid, valve cover replacement due to leakage, etc. Went to my mechanic who inspected my vehicle and told me none of this was necessary, but noted that the front wheel bearings may need repacking in the near future at a cost of $380. Don't trust Big O Tires in Sebastopol. It used to be OK but is no longer. read more

My husband and I had JUST started our roadtrip from San Francisco in our rental car. Within 2 hours we realized one of our tires was covered in nails. Luckily, we made it to Big O Tires and they turned an extremely unfortunate and stressful situation into a great memory! Ron and Ethan went above and beyond for us and we could not be more grateful for them. Their kindness and can do attitude turned our day around. Thank you Ron and Ethan! read more

This place is full of clowns pretending to be mechanics. Do not believe a single word coming from anyone at this location. I personally watched them damage my car, then lie about it, and then hand me a bill that was 4× the original estimate. Bring your vehicle anywhere, but the Sebastopol Big-O. I own a 5-star service business and wouldn't dream of hiring any of these people for my establishment. Save your time and your money and go to any other shop in Sebastopol!!! read more

Professional service with excellent customer care. Big O Tires in Sebastopol provides my family with regular oil changes, tire replacement, rotations, and brake checks. They answer the phone and work around schedules and always find an appointment for our vehicles. They know your name and go the extra mile to ensure we are happy with our service. I had a scraping sound in the back passenger tire and brought the car in today. They checked out my brakes and identified the problem and sent me on my way with a well running vehicle at no charge. We highly recommend Big O Tires. read more

Another great service experience from Javier and the entire team at Big O. They seem to be able to diagnose and repair a wide variety of automotive problems, not just tires! This time it was our air conditioning. It was not working properly, but a few hours later it's blowing like theArctic. Thank you, Javier ! read more

Would give zero stars if I could Do not go here. Purchased warranty tires should've lasted about 40,000 miles got 12,500 miles in a little over two years. Owner tries to talk to you like you're an idiot. Would not honor warranty. Went to Les swab. They treated me with respect not like I was some stupid girl that doesn't know how warranty works. The owner said he would make right on it. "check is in the mail" never saw anything wanted to give me $61.25 "prorate on new tires from his shop. Hard no. Save yourself a headache go to Les Schwab in Rohnert Park totally worth the drive. Just bought tires for all of my cars. read more

I wish we'd never bought tires here. We got the warranty, so we've had to keep bringing our car in for tire issues. Every time, we call ahead to schedule so that neither my husband or I has to sit indefinitely, so that we can actually get to school pick up in time or whatever. And every time, we still end up sitting, sometimes waiting a couple hours for anyone to have the time to patch the problem tire. Most recently, my husband sat a couple hours and was sent away because the technician wouldn't believe or couldn't understand that we were very sure that the tire was really going flat every other day and he insisted the issue was just the sensor. So of course I sent my husband back and he had to sit for hours again and the technician performed the exact same basic inspection and tried to dismiss the problem as a faulty sensor. This time at least my husband insisted they look closer and sure enough they only needed ten minutes to find the faulty valve and replace it. For the number of hours we've spent just sitting for these people to spend minutes on small fixes, whatever price they gave me when I bought the tires in the first place wasn't worth it. read more

A panel from underneath my car had come loose and was dragging. I drove into the BIg O in Sebastopol, CA and Xavier and Mike attended to the problem right away, even though it was 15 minutes from closing time . I really appreciated their immediate attention, service and great attitude. Thanks! read more

I had a blown tire and went to Big-O Tires because it was the closest place and I was driving around on my spare tire. After the tire replacement, the rep, Javier Garcia, claimed my front brake pads were metal on metal, urging an immediate $500 service. I wanted a second opinion, and I happen to work for a tree company that has an amazing onsite mechanic. The next day I consulted my workplace mechanic who found the pads were fine. He said my brakes were absolutely no where near being metal on metal. Big-O Tires lied, attempting to overcharge and extort. As a trusting customer, their dishonesty is disappointing. Shame on Big-O Tires for unethical practices. read more

Very disappointed with Big O Sebastopol. I bring my car in for a very "simple" screw removal tire repair and rotation/mount and balance. Well they removed the screw "supposedly" but absolutely failed to balance my tires which creates speed shakes when taking my car on a family trip. Took my car to Firestone and they found a nail in the same spot of the tire but on a different side of the car due to the rotation but they confirmed that they didn't even bother to balance my tires at all and just rotated. I was charged $40 for the "rotation and mount and balance" and another $40 for the repair. It's apparent these guys either don't know what they are doing or simply don't care and have no problem taking your money. My advice, always buy and deal with your tires at a Costco cause those guys really put the care into their work, or just go to someone else. These guys at Big O just take your money. I will not do business with again. read more

The buisness is honest, helpful in many areas other than just tires , friendly and efficient. The service advisor, Ywaldo Gasque brought it to my attention that my tires were still under warranty, which the company I bought them from failed to mention, saving me over $400. I'm seen in a timely manner and feel that as a customer my business is appreciated. Great service, good customer relations, and a business you feel good supporting. , read more

I used BiG O for years and recommended it to people. It USED to be okay. I brought my car in to change an alternator. When I got it back,there were strange sounds that the car wasn't making before I brought it in. The "Manager" said he would charge me $180 to inspect it when all he really needed to do was connect it to the machine that checks the codes. from other peoples reviews on YELP , it seems like more damage gets done then repair at BIG O's. They make sure you'll have something to come back with and charge you with a 180$ inspection to start. needless to say, I Highly recommend to find a different mechanic in Sebastopol. read more
