Fast, convenient, and courteous. I had 3 hours to spare in South Natomas so I figured I'd get some car maintenance out of the way. I called on a Monday morning about a tire rotation, oil change, and smog check. They told me sure, head on over. After explaining the charges for each (which were acceptable based on other rates that I had checked in the area), they got to work and sent me on my way after 25-30 minutes. Impressive stuff. As an added bonus, the waiting room is quite spacious with comfortable leather couches. They have a couple of light snacks, water, and coffee as well. I can't recall the last time I felt content waiting for my car to get fixed up. These guys will have my business again. read more

Mr. G was great as always. He took excellent care of my 2021 BMW 530i on several occasions, and has fair, reasonable prices. I got my car battery replaced amongst a few other services. From my first visit, I could tell this isn't the kind of shop that tries to upsell unnecessary repairs or take advantage of customers. They are quick, efficient, and professional. It's hard to find a mechanic you can trust. Highly recommend! read more

I have a scion XD that has been serviced here since I have owned it. They have taken cared of the maintenance oil changes; Every issue that has raised from shocks to electrical coils component replacement. The quality is top notch and the value is fair with the service pricing. It is so rare to find an all in one shop that can do what these guys achieve. A+ and highly recommend their work to anyone! read more

Service was very quick. Was able to get in and out within and hour and a half. Great customer service.

Stopped in for a smog check during the week. I was there for no more than 20 minutes. I was so impressed by the customer service and the car service. I will be back! read more

Trustworthy local mechanic. This is my go-to spot for any tune ups and oil changes! Very friendly and quick service!

I've been a customer for approximately 6 years. I've never had a mechanic that I fully trusted until One Stop Smog. Great customer service, awesome and trusting mechanics!!! 100% valued! read more

I was in and out so quick. The only negative was the cost of doing a smog check on a motorhome. But I checked pricing and they charged appropriately. Very nice people. read more

Made an appointment with Raj on 10:00 Saturday morning and I was out of there by 11:30. Super friendly and efficient service. I highly recommend this shop for not only smogs but any issue you might have with your vehicle. Raj was polite and explained to me exactly what he was doing and had no problem when I asked him to also do an oil change. Great value, efficient service and quality work. Thank you Raj and crew so much! Will be seeing you again if I have any issues with my car. read more

I don't do reviews often. But One Stop Smog & Auto Repair is the best mechanic I've been to. No joke. I've taken my car to multiple mechanics for a persistent check engine light and intermittent battery/charging concerns, and I kept getting the same answer: "It's the MAF sensor." I replaced the MAF and the problem still wouldn't go away. I brought it to One Stop Smog & Auto Repair and the difference was immediate. They didn't guess--they did a truly extensive diagnostic that took hours, including a smoke test of the intake system. They found, among other things, a torn PCV hose causing an intake leak, and they replaced it. The biggest surprise? When I came to pick up my car, they told me there was no charge. I've been quoted up to $200 for diagnostics like that elsewhere. Honest, thorough, and genuinely charitable. I can't say enough good things--customer for life. Definitely RECOMMEND One Stop Smog & Auto Repair! read more

These guys are amazing mechanics. They say they can fix it , and they definitely do , prices Are fantastic . I had trouble with my AC they Fixed it great price even my heater works better Now. Thanks Raj read more

Easiest smog check ever. In and out within 30 mins! Great customer service and reasonable price. I'd come back!

The prices are fair, the shop is clean, and the customer service is unmatched. I feel completely comfortable bringing my car here, and I always leave with peace of mind. This is my go-to place for all my car needs now. Highly, highly recommend! read more

Great place, can't stress that enough. Great guys here, and they made a bad situation, such as car problems, into a very easy process. With a vehicle from the late 90's that I might unfortunately finally have to part ways with soon, I've been to a few auto shops in the area and this place has by far been my best experience. Car problems are inevitable, but I know where I will be getting those problems solved moving forward. read more

Raj the owner is a good guy and does great work I even let him experiment on my jeep Cherokee SRT transmission I wanted to swap it he said let me try something so I got the supplies he asked for I picked it up the next day and that truck ran flawlessly for the next 4 years I had it always a good experience with smog or mechanical work read more

A very famous lyricist , Neil Peart of the band Rush once stated: "the most endangered species? The honest man." One Stop Smog and Repair run by Mr. Singh and his son Raj epitomize honesty, integrity, dedication and punctuality. Let's just put it this way. My wife and I drive from Emeryville to Sacramento for the specific reason to get all repairs and servicing done at this place. We've been doing it for years and this is testimony to the outstanding customer service and integrity you will receive at this place. Thank you Mr. Singh...thank you Raj! read more

I have been bringing my cars to Raj and the guys over at one stop smog for about 10 years! I recommend them to anyone I know because they are honest, great at what they do and overall just great people. I wouldn't go anywhere else when it comes to my vehicles! read more

Raj and all the staff here are great people and know their jobs! And what I appreciate most of all about this shop they never take advantage of the fact I'm a woman and may not know everything about cars. Their prices are more than fair and excellent quality. read more

June 9, 2025 I took my truck into One Stop to have them analyze a number of issues. I worked with Raj, who was very polite and professional. We agreed to have him check out my A/C (I thought it was going to need a complete rebuild), Raj found 2 bad Shrader valves, an easy repair and after a recharged system My truck was up and running COOL for this summer and the Price was very Fair. It's Great to have Honest and Fair Mechanics in my neighborhood. I will be using One Stop to service and Repair my vehicles in the future.

The prices are more than fair and the work is done quickly. I pray they don't become victims of their success because the shop is small. I want it to be my primary location for auto repair. read more

We came here after a HORRIBLE EXPERIENCE with Northstar Smog and Auto Care on 3214 Northgate Blvd. They don't do a lot of chit chatting here because they're busy getting you in and out. It's hard to find an honest business these days. They answered all questions, both on the phone and in person. Reasonably priced. Call them first and they'll tell you the best time to go so you won't have to wait around. I have brought two vehicles here so far and will continue to bring my vehicles to get smogged and will continue to refer them to friends and colleagues. read more

amazing crew, knowledgeable and friendly guys. I've been here multiple times for various reasons; O2 sensor, oil change, radiator failure, etc. Check them out if you ever need your car repaired read more

Came here for two smog checks and was in and out under the time they had originally estimated. Service was good and everything was taken care of. Would definitely come back as it was on the affordable end compared to other places I've gone to in the past. read more

I arrived first thing in the morning when they opened and they had my smog done and had me checked out within about 25 minutes. They're friendly, fast, and a very reasonable price. I'll be taking my car to One Stop for every smog test until the DMV tells me I have to go to a test only station. read more

Mr. Singh, Mr. G and crew are great. They're honest and aren't out just to make a buck!! They respect your time and how hard you work for your money! Come check them out. read more

MY ONE AND ONLY! I have been coming here for years, and have only ever been treated well. Raj is always so patient and helpful with anything I need! He is so good with explaining what needs to be done, or what service he's providing to me which I truly appreciate. I like knowing specifics of whatever it may be- oil change, service, buying new tires, or even adding some cosmetic additions to my car. Raj has always been there any time I had flats, or needed servicing. Everyone is treated with respect like family here, and I appreciate them. Today's service was cosmetic- painting my brake calipers! Raj is always so accommodating and makes it happen. I appreciate that he takes his time with everything. No rush, no "half-ass" shit here. read more

I brought my truck with automatic transmission in for alignment 2/4/2025. I asked them to correct my steering wheel to be centered. Afterward, when I left the shop, the steering wheel is off to the right side. Brought it back and the owner insisted on driving my truck and saying "my son is a professional" and he kept shouting about his friends who hunts and gave meat to him and kept asking me if I hunt after I repeatedly told him I do not hunt and only fish. He put in manual gear until I asked him to put into Drive and speeding down N. Market drive, Northgate and to highway 80 and and exit onto Truxel and the whole time he said excitedly "it is centered" while I could not get a word. I drove today on I-80 from Watt to Northgate and the steering wheel is way off going straight line with no turn on the highway. I cannot take picture since I was driving and only want to let all know since I will not come back to this business. AVOID at all cost. Update. Shop called and my truck steering is now straight. Updated the rating to 5 stars. read more

Natomas area pay attention, this family run Auto shop is hands down the one to check-in with.

Amazing customer service and they were quick and efficient with changing out my smog and ac filters.

Great mechanics at this business. They are passionate and true to their job and take pride in what they do. We are usual customers and love the business that they provide us anytime we need maintenance with our cars. Great deals and prices too! read more

Came in earlier today to get my car smogged, oil changed (long overdue) and look into a couple of minor issues (key fobs not working and slight rattling noise when accelerating). Rajpreet was extremely helpful by immediately looking at my keyfobs and noticing that the metal touchpoints weren't making contact. Quickly adjusted the touchpoints and both key fobs worked. This saved me a couple hundred dollars as I was about to order new fobs and have them reprogrammed. They quickly performed the smog check and confirmed no issues. Then provided an oil change and then Rajpreet's father took me in the car for a quick spin to check on the rattling noise. Luckily, the noise went away as he confirmed that he didn't notice any loose connections or issues that would've caused the sound. He was helpful in providing advice on my car as I'm nearing 85k miles. Picked up the keys and checkout was a smooth process. Will definitely be going back again. Do yourself a favor and drop by to get your car serviced by an honest and professional staff who will go above and beyond. *** Bonus Points *** for Scooby, a sweetheart, shop dog who loves being pet and rubbed behind the ears while you wait for you car. read more
