Big O Tires 987 Francisco Boulevard East, San Rafael, CA 94901

"Excellent service. I was tire shopping this weekend and I went to three different places. I was getting wait times up to 6 hours. I called big o tires San Rafael they gave me an appointment and were able to get me in and out in less than an hour. Eric at the desk was amazing. He is genuine and honest. You can tell he really enjoys helping customers and does what’s right for them. The two guys who were installing the tires and doing the alignment were really nice. Don’t waste your time calling other tire shops this is the place to come."

"Thank you. I am very happy with customer service. Very pleased with price range options. I got tires that needed ordering, and made an appointment for service. The service department completed the work expeditiously and completed the job in less than the estimated time. I would recommend the opportunity for my friends to shop Big O Tire. Thanks again."

"They destroyed my engine and replaced it with the wrong model--do not trust their work! I took my Kia here for a simple oil change. They failed to properly secure the oil pan when they were finished. Hours later, the oil pan completely fell off while I was on the freeway. The engine seized up, causing me to lose the power brakes and steering while traveling at highway speeds, and I was just lucky that there weren't many other cars around, or there might have been a serious accident. When I managed to stop, the engine was smoking and didn't have a drop of oil in it. I had it towed back to Big O; the next day, they replaced the oil & pan, then determined that the motor was blown and needed to be replaced. They kept my car for a week or so while they located an engine and installed it. I was told that an appropriate, used replacement engine "with the same specs" had been installed but no description of this engine was provided to me. After the oil change went so badly, I didn't trust their work so I took the car to the dealership to have some Kia specialists inspect it. They found that the installed engine was not a 1:1 replacement as I had been led to believe. I was given an engine with dual variable valve timing even though my previous engine was single. It's still unclear whether this discrepancy will cause mechanical problems, or whether the unconnected hookups, left exposed, will also cause issues. Big O made no effort to explain this change to me; in fact they actively hid it from me by lying about the engine being "the same" and refusing to give me any paperwork about it. I had to go to the Kia dealership (and pay $$$) in order to learn what was ACTUALLY done to my car. This makes me think that Big O management knows it will be a problem, and they hoped that if they didn't say anything, I wouldn't notice what they had done. This situation has dragged on for over a month, and the most I have been able to get out of Big O is a screenshot of a partial Carfax report on the VIN from which the used engine was taken. I would assume that some documentation on the engine and its mileage would be a standard part of the transaction when they purchased it from the seller. The fact that Big O has refused to provide such documentation suggests that they don't have it-- either they failed to record it and don't want to admit it, or they got the engine from some chop shop to minimize the cost of fixing their screwup. Whatever the reason, now I'm left with a car with no resale value, since it has the wrong engine AND no real proof of the engine's background. Photos show the new engine's wiring that has nothing in my car to connect to and is left exposed, and the sloppy application of sealant. Also, a bonus photo: the absolute mess of a welding job that they did as a "courtesy." Big O should be completely embarrassed by letting this poor caliber of work leave their garage, and their customer service is a joke given the way they have treated me-- especially after their initial screwup could have gotten me (and my passenger) killed! I have previously had good experiences with other Big O locations, but will not be giving this company any more of my business after the way I've been treated."

"Very good experience. Made recommendations and happy with my tire choice. I take my car for most all services to Big O."

"Friendly and prompt service, clean lobby and restrooms. My oil change and tire rotation were done faster than promised. Update 9-20-23 You're welcome, I was really impressed with your shop. The only thing more I could ask is for you to send me a burrito from that great little Taqueria around the corner!"
