Simple, quick, cheap smog. Ive been here twice now for both an obd1 and obd2 smog and in both times I was taken in without an appt and was in and out in roughly around 30 mins each time. Smog tech and owner, Vu (i think was his name) was helpful and friendly on both times. read more

I honestly wanted to like these guys and have them be my regular mechanics, but I've been burned by them one too many times. They were initially recommended to me by a AAA tech who helped me out with my car battery. I went to their Santa Clara location and their mechanic was out for the day because of an emergency, so I said no problem and went back the next day. I received good, honestly priced and quick service that time, so I didn't hold it against them and went back a second time a couple months later to get my car smogged. Firstly, their Santa Clara location doesn't do STAR smogs, so my bad - although it's in the name. They told me to go up to the Sunnyvale location so I did, where I was told the tech left for lunch or something and would be back in an hour. Since I was already there and it wasn't too far from a dry place to sit as it was raining that day, I left the car with them and went somewhere else to wait. About 30 minutes later I get a call saying the tech was not coming back for the day and to come get my car. O...Kay. Not cool. Sorry, but I won't be back. read more

Vu fixed my car. Replaced break and break fluid, oil change and replaced coolant. It was done on time and price was fair. I recommend this shop for basic service. read more

When my car wouldn't start, the AAA technician suggested bringing my car to this place to replace the starter (problem was not the battery) and definitely not the dealership. The tech called Vu (the owner) on the phone, and Vu immediately gave a quote, and told me that he'll have the car ready the next morning (it was past the shop's closing time). After my car was towed to this shop, Vu had the repair done the next day as he mentioned and charged me the quoted price. Thank you so much, Vu, for your awesome service!! read more

I was referred here by an AAA worker after having some engine issues a few years ago and ever since then this has been my go-to auto repair shop. Vu, the owner has basically become my go to car guy in terms of repairs, oil changes, questions, anything you name it. He's very helpful and responsive and gives me the best advice to help save my money. The services he provides are super reasonably priced, don't think I've found a cheaper and more quality place than his. Reliable and affordable would be the two words I describe this shop. read more

Great job, fast service! Would recommend for smog testing any day. In and out in no time at all.

Vu was great to talk to. I explained the problem and he gave me a quote straight away. I shared some pictures and he knew what the problem was, he needed to order some parts and he did that and shared it with me as well which helped me get the repair done faster. He may not necessarily be the cheapest but he quoted me a fair and reasonable price and provided a good service. read more

I recommend mentioning about the Yelp discount to get a few dollars off your service! I called on a Sunday afternoon needing a smog check and the workers let me know I can just walk in whenever. The smog check went by very smooth and the DMV received the certificate almost immediately! read more

If you want to leave broke and with more problems than you came with, then come here! AAA needs to seriously stop recommending this shop and I am going to share why I feel that way. Our daughter's 2011 Infiniti G37 would not turn off so AAA towed it here. The mechanic claimed the battery needed to be replaced HOWEVER the battery is brand new with only !,452 miles on it (replaced 8/20/24). In addition, he said the BCM (Body Control Module) needed replacement for $854. The battery was disconnected (and drained!!) as a temporary fix to shut off the car and he was unable to turn it back on; he claimed it was due to the aftermarket kill switch that was installed. The kill switch had nothing to do with the car not turning on so we had it towed again - far, far, away from this shop!!!!!!! I was actually advised by another mechanic that only the dealership should replace the BCM due to the fact that it needs to be programmed to the car! What was the problem you ask? Simply enough, the key fob!!!!!!! SAVE YOUR HARD EARNED MONEY - DO NOT COME HERE! RESPONSE: You didn't charge me because you couldn't figure out how to turn the car on which required my husband and his mechanic to come down. Correct or not?! Yes - I have the text stating ' Imma pass'. If the car wasn't correctly diagnosed then there is nothing to charge for!!!! The car runs flawlessly now. read more

Got my smog check done at Keep it Runnin in Sunnyvale and it couldn't have been easier. Vu took care of it quickly with no fuss--super straightforward and easy to work with. I didn't even need an appointment. Great spot if you want fast, no-hassle service! read more

I brought my Honda Fit car there for a smog check, recommended by Jaffa From Cupertino. Vu was very personable, and friendly. The technician ran the test and completed the task. The price was reasonable. Super good service. I will return for other services in the near future, Check them out! read more

TLDR: Great Smog Check price It's a Yelp deal. Mention yelp and you dont' really have to check-in, even though I did. Just mention the yelp deal and the guy will give you the discount. I like that he's pretty laid back. There was one guy ahead of me, but it didn't take long at all. In and out. It's a bit hard to find parking, I just parked kinda in the middle of the parking lot actually. It's inside a gas station. read more

Professional, efficient, and fair prices. I came here for a smog check without an appointment. It was first come first serve - they let me know one person was ahead and asked if I could wait. My smog check took max 15 mins. The owner/representative honored the Yelp quote ($40) he gave the day before. Highly recommend! read more

Went for a quick smog check for my vehicle. Pretty straightforward with no hassle. The guy was also friendly. The price I paid was very reasonable. Highly recommended read more

Great experience diagnosing and replacing and alternator issue here. Would definitely recommend!

Got a few smog checks here Might have to wait in line for a few minutes depending on when you go. I came by before lunch on a Sunday and only had to wait for the guy in front of me. Was in and out in 30mins. Mention the yelp deal and he'll drop the price. Will be returning next year for my next smog for sure read more

Great experience here! Fast, friendly service, and I was in and out in no time. Highly recommend!

Super fast and easy SMOG check. Very affordable prices! Remember to see Vu for all your repair needs, very chill guy

Fast service and easy to park! It's attached to a gas station so it can be a bit busy.

The service is really good and the price is really great. After knowing this place, never go to other places read more

I want to say this place was a life saver this weekend. We drove up to San Jose from LA on Friday for a tournament and we were 1/2 a mile from our destination at 6:30pm when my car felt weird and pulled over, parked , and powered off my car. Attempted to turn it on and it wouldn't start. All of the local shops were closed and some not even open till Monday. 2 repair shops and 3 tow trucks later we are referred to Keep it Running by Jack from AAA. Saturday afternoon at 3:30pm we arrive and it took the owner 5 my minutes to figure out the problem. The apart was ordered and it arrived Sunday and I was in the road home by 4:30pm. This place was amazing and did mention they even waited for me after the shop was closed so I could pick my car to drive back home to LA. I would definite recommend this place. If I'm ever in this area again I know I have a place to take it to. Thank you Keep it Runnin you honestly saved the day. read more

Not very many shops are open on Sundays, but I stumbled upon Keep It Runnin Smog when I thought I had a nail in my tire. I did a Yelp search and found this place. I drove to the location and there were two gentlemen there to help. I think they might have been a father-son duo. The older gentleman helped me right away and informed me that my tire was just lacking air. He pumped it up and didn't even charge me. Another guy arrived and he brought coffee for the two other guys, which I thought was a nice gesture. Who wants to work on a Sunday? Anyhow, I asked again if they were sure I didn't need to pay, and they insisted there was no charge. Pretty noble. 2nd visit to Keep It Runnin was for an oil change for my Toyota Corolla. I've been lagging on it and again decided Sunday would be the day. I called the shop around 10am and the younger gentleman picked up. Asked for the price and he quoted me $50. I asked how busy they were and he said just to come on over. I drove up and I was in and out in less than 10 mins. He also honor the price of $50 and even got synthetic. Other places typically charge $60-70 in the Sunnyvale area. Definitely returning for future oil changes. read more

Vu was super kind and professional. How shop was one of the few shops that was open on a Sunday afternoon and got me in and out of there quickly. 10/10 would recommend read more

Open on a Sunday, picked up the phone after the first ring, one simple price for a smog check that includes the cert, 10 minute wait. Couldn't ask for a better/smoother transaction. read more

My Registration Renewal needed a smog certification. Came here to Keep It Runnin, because they've worked on my engine replacement before. And decided to get my Smog here as well, i was in n out fairly quickly. the time i got there, no cars in line, and also Vu honored my Yelp check in discount. Thank You! read more

Went for smog check. Great service, was done in under 15 minutes, all good, price very reasonable

Super fast and great value smog check for my vehicle. The smog technician was very helpful and took care of me quickly. I will say the only 2 things they could improve is have better signage of where to park and if its okay to park behind and block their bays as I was directed to do after I had already parked in the parking lot behind the building. Second understanding your paying the smog technician in the bay not the clerk inside the gas station convince store. read more

Quick smog check and they allowed me to use the Yelp discount. I can't comment on other services yet since I haven't tried them

Quick, responsive and honest mechanic! After one of our vehicles had been sitting awhile due to the pandemic, we needed a quick turnaround on an oil change and general inspection for an upcoming road trip. Vu, the owner, was friendly and squeezed our service in on a holiday when many places were closed or super booked. Vu was efficient, only recommended what we needed and was so friendly and helpful. We ended up with an oil change, perfectly filled tires and peace of mind that the rest of the car looked good (general inspection). I highly recommend Keep it Runnin, we will be back! read more

The service for the smog check was fantastic - in and out in ten minutes. However, they had stated online that the charge would be $40 including the transmission fee. When it came time to get paid, they tried to charge $50 instead of $40. Buyer BEWARE!! read more

Owner is rude，fee is very expensive. Will NOT come here again. The owner shared the price in the middle of repairing.

Got a nail in my tire and Anthony was able to fix it under 10 mins. Super fast and great service!

Towed my car there to clean out diesel accidentally added to my gas car. Friendly owner, prompt communication and quick job done. Would definitely visit again. read more

Advanced Repair shop you can count on Generous employees of the work Station and a thoughtful boss.

Very professional. In and out within 15 minutes. All around great service! I would come again.

First and foremost, let me just say God must've sent me here. Earlier in the year, my car started to lightly jerk as I would accelerate on the pedal. It would slow down and kick-push pretty hard. It was annoying me for a year. Well today was the day I finally had to do something about it. I don't know much about cars and everything from maintaining the simple stuff such as an oil change is about the only thing I know about.. oh, and little stuff with tires lol. Every time I went to get an oil change, the mechanics from Jiffy Lube (NEVER AGAIN), would tell me there were no leaks and all my oils were filled up. Well after half a year, my car started slowly to act up on me such as little jerks. Earlier today as I was driving, my car would jerk to the max; only this time it was worse. It would drive for a couple minutes but once I came to a full stop, my car would accelerate and I can hear the engine going but my car wouldn't move? I was stuck in one place as if my car was on PARK and I'm pushing on the pedal for no reason. Once I turned off my car fully and turned it back on, I was able to drive for another cool couple mins and then it'd repeat again. I was embarrassed and I was holding up some traffic behind me. This was dangerous and serious. It wasn't until I pulled over at 76 for some gas and spotted this man who was the mechanic/owner of the shop. I carefully explained to him what I was feeling and how my car was acting and he went straight to recommending me getting my transmission oil changed. It has been probably a little over two years since I changed my transmission oil . Vu, the owner, had lifted my car and showed me the leaks and how bad my gasket was. As he began to unscrew each bolt from the tray, the oil started to drip out. He collected the oil onto a pan and examined it with me; it was pure black, muddy, short on amount, etc. Lots of crud in between everything and it was totally time to get things going. Vu is a knowledgable man with patience and great manners. He has total respect for me and went on explaining in great detail of what was exactly happening. He was reassuring and kind so I didn't have the feeling of worrisome. Vu took his time from point A to point B without losing track. He was able to tell his story about his mechanic life and where he's from while fixing my car. This was very impressive. He doesn't play around with short cuts either, instead he did everything the real way which was carefully turning bolts, cleaning the trays, applying this glue substance onto my tray, pouring the oil, etc. Once everything was completed, he then took my steering wheel and shift stick to manually turn the shifts from better rotation. I had put my 100% trust in him and so far my car is feeling different. It's smoother and easy going. He made everything worth while but interesting at the same time. He's the best in the business and I can't thank him enough. If ANYONE OUT HERE in the South Bay, looking for a great mechanic shop with an awesome mechanic, check this place out. I totally recommend people coming here for a great check up and for fixings. Vu is compassionate and truly cares for his customers. He is attentive and shows great respect for his craft. I've never witnessed anything like this first hand and watching a mechanic like Vu, demonstrate the art of fixing something while keeping a calm atmosphere. There is no one doing it better than him right now. This place is the NEW hot spot for car repairs. If you do decide to come by, tell Vu Ngo that Allister sent you!! Thank you for everything Vu. May god bless you! read more

See all

Not only do they do smog testing, they do all sorts of other car service and repairs. On top of the smog test and oil change I'd brought it in for, Vu knew immediately what was wrong with my clicky steering wheel, and had the part needed to replace it on hand already. I appreciated that they showed me exactly what they were going to do and even pointed me towards some YouTube videos to show precisely what it is that breaks down in the steering column. No upsell or added complications, and they had my car back to me ahead of schedule and within the estimate. And if you happen to be there around a meal time, grab something from one of the food trucks. Gasoline's cheap too. Absolutely my new favorite auto repair place. read more

Needed to do a full synthetic Oil Change for the bf's car that i borrowed from LA. Of course i searched my trusty yelp, made a few calls, got quoted stupid pricing (for some reason just because its the bay people charge arm and a leg), and then found this place. Vu picked up the phone and Vu quoted a very good low price but my friend was skeptical about the low price so he went with me. When i got there my friend question him about the oils and filter and it turned out Vu had quoted me for everest oil which is still good but lower performance and I wanted Mobile 1. Vu re-quoted me and it was still way lower then the competition. Shoot even lower then my LA auto guy. Of course i went with it and my friend was watching them and said they did good for a oil change. Vu is hilarious and straight forward. Probably the most funniest auto guy I met. He interacts with his customers which i thought was good. The shop is located in a 76 gas station and only been open for 6 months. Probably the most entertaining oil change shop with courtesy service. At least he doesnt BS. They are still new and its my first time here but so far its good. I would come back for his services again. One thing to note, no close in house seating so bring a jacket on the cold days. There are seating but its open and today was cold... read more

Keep It Runnin Smog & Auto Repair - Auto Repair Near Me - Sunnyvale, California

Anthony at Keep It Runnin was very helpful and friendly. I highly recommend Keep It Runnin for you car needs.

I've finally found an auto-mechanic I trust. Took my Ford Mustang to the Ford Service-place on Steven's Creek, San Jose two years ago. Carefully explained that it kept running out of coolant, and the AC wasn't working, AND that I had had it looked at by an auto-mechanic in Redwood City two months earlier, and they had told me nothing was wrong, when clearly there was. Ford charged me $700 dollars, told me everything's fine, just refill freons. Same problems persisted, so we've been driving around refilling coolant every time we fill up gas, and have had no AC - for two years. (Having spent $400 + $700, with nothing resolved, we lost hope.) Took it back to Ford, after carefully explaining to them, they did a better job this time and found a broken AC compressor and a broken water pump (diagnostics $200). Quote to get it fixed? $1,850 + $850 + taxes, plus they said that after they had replaced the compressor they'd have to do additional diagnostics. So essentially it would cost me more than $3,000. While the Ford was still at Ford, I reached out to get quotes on Yelp, Vu was the quickest, with full transparency - offered a screenshot, and also corrected me on a number of things that needn't get done and so on. Substantially better price....! Transparency, honesty, non-BS, straight-forward communication with no-nonsense. This is where you take your car. Everyone makes mistakes, but at least here, I'm sure they'll be honest mistakes. (And haven't come across any yet.) read more
