If it was no 79 dlls .charge is because I refused to paid for the bogus inspection you offered me. Be just a little honest ( try at least ) and you'll get satisfied costumers. Good bye mister read more

I appreciate that JJ's offered its services through this website to fix the problem, but when I had alerted (at the time and place) they were not so helpful, even questioned me if they had actually done what I say they did. I went to get my sunroof and electronic locks fixed. The locks now (after getting them fixed) only lock if certain doors are closed and when they took off the roof to repair the sunroof, my backseat lights became loose and I wasn't able to push them on. They were very resistant to admitting that they messed them up. After going back and forth with them, I decided I'd rather just pay someone else. But, the main point of the story. A little over a year later, my sunroof has come undone. A piece feel off when I opened it. I RARELY use it. Maaaaaybe once a month and when this happened it made me want to revisit and update this review, but maybe this random loose falling piece has nothing to do with them, but it did make me want to clear up my original review and thank JJ's for offering to fix AFTER I had already asked them to do it. Thank you, but no thank you. read more

Been coming here for about 7 yrs and JJ and his team always provide quality services for great prices. Their customer service is always great and reassuring. read more

Honest shop. Very prompt and courteous service and discount online coupon. Recommended.

My wife's car needed a smog check. She left it with them. Of course they found something wrong that needed to be fixed. Over the phone she was told $300. When we went to pick it up, the cost was $430. Naturally, she argued but JJ gave her the quote over the phone wasn't there. Never again!!!! Stay away !!! One price over the phone and another in writing!! read more

Took my car for parts that had to be diagnosed/replaced around 9am, got my vehicle back issue free by 4pm. 12/10.

garages are all the same right? not so with jj's. the owner is super nice; he took the time to explain the problem my car was having and how he planned to fix it. (even though the shop was busy he took the time to answer my questions) speaking of the shop; this place is easy to find and super clean. I mean no problem with my wife or daughter using the restroom, you can wear white and not get dirty clean. the staff and quality of work is superior to other local shops. i recommend this shop! read more

I went to JJ's auto service today and purchased 4 new tires. I was at a different auto shop ~ 1 year ago and was informed by the mechanics that all my pressure sensors were bad abs need replacement. They wanted $300 dollars to replace all 4. I declined that service. Today, I told the mechanic at JJ's auto service to replace all 4 sensors but the mechanic checked the sensors and only one was bad. Only one was replaced saving me a lot of money. Finding an honest auto shop is rare these days but they still exist. Thank you JJ's auto service for your honesty and professional service. read more

I was originally quoted $10,000 by Kia for my engine. JJ's was able to rebuild my engine plus more AND detailed my car for under $5,500. I am eternally grateful for this team. I was fighting with Kia for almost 3 months and JJ's took less than 2 weeks to get the parts and do the labor. I highly recommend them ! I'll only take my car here from now on. read more

This place is absolutely amazing! Needed to change brakes for my car & I had no idea where to go! A friend of mine recommend JJ's Auto service. I gave them a shot and they did a great job fixing the car. read more

Worst pre purchase inspection total RIP off didn't do anything but showed me it was leaking oil. Asked about transmission didn't know anything but said I could pay another $90 and leave it to figure it out. What did I pay the first $90 for ? read more

This auto shop does great work. I do agree they are professional and the job gets done right. After spending thousands of dollars (brought several family member cars here), it looks like it was money well spent! read more

I was very pleased with your team's quick and thorough work and have always appreciated your honest, straight forward approach. As I have in the past, we will continue to refer those in need of automotive repair and body work to your shop and am happy to provide reference to your good work to any of those who would inquire. Thank you! Andy read more

I honestly don't know how this place has so many stars. I had to wait hours for something that should have only taken a half an hour. JJ was rude and not helpful at all. He seemed like he didn't care. I had to leave my car and i left it as early as possible, but i could tell that they didn't even start to attempt to work on my car until i showed up again. I'd call to check in on my car he would rush me off the phone and not answer any of my questions, so i finally just came back and they were blaming the insurance company for not being able to do anything, but when i called the insurance company, i discovered that the insurance company was trying to help, but JJ wasn't responding to them either. When i talked to him, he made me send the information to the insurance company myself. (And my insurance responded super quick and gave approval fast). Once again i felt like JJ didn't care about my car issues. 8hrs later at closing i finally got my car back, but i had to come back for the paperwork. When i came in to sign and get a copy, JJ practically threw the paper at me and said "hre!" And i asked if i needed to sign anything and he said no and walked away talking on the phone. I feel like the mechanic staff seemed nice and maybe i caught JJ on two bad days, but he was rude with me and not helpful at all. I was not satisfied with him at all and i do not plan to come back here. I wish i had a more positive experience like apparently many of the other people who have posted reviews, but my experience was terrible unfortunately. Update: my check engine light actually went on 4 days after JJ "fixed the problem" and the issue was not actually fixed at all. I had to take my car to a different mechanic and they said it was the same issue that JJ initially told me, but they said it looked like it wasn't even touched. I had to get my car fixed by the other mechanic. This time it was actually fixed. So i do not take back my comment of JJ's not being helpful. It was more of a headache than anything. I was not going to post the update, but i did see that JJ responded, so i decided i would post the update. I did not want to take my car back to JJ's because i did not trust the service since i wasted an entire day there and the experience was so negative. read more

Great customer service, super reliable, fast and friendly every time I come to JJ's I always leave feeling like my business was appreciated and it was money well spent I've never been back for the same thing twice read more

Great customer service and genuine people. Andy is the best, brought in my car for a smog check after a previous shop had denied my service due to my service light being previously on. The car passed the smog and they had knowledgeable input on future service that may be needed on my LR2. I'm so happy I ran into this place. read more

Came in for a much needed smog check this morning, and was totally pleased with the service. No appointment was needed, the waiting room was clean and pleasant. Customer service was top notch; friendly, no up selling or BS, they honored my coupon that I had on my phone, and I was back on my way in under 20 minutes. Thanks, guys! read more

After having been to the Mazda dealer and another shop, I am so glad I found JJ's... It is always difficult to find reliable people to work on your car as a woman with no clue of what's inside a car... As I write this, they are working on my car... I'm feel at ease to know that such honest and knowledgeable team is ensuring my safety.. I have found my car's care takers.. read more

JJ auto service is the place to go for any mechanical issues with your car! I've been going to JJ's for about three years now no I am very satisfy with their service and especially their prices.

I've known JJ for years now. He's been taking care of all my cars. Honest, affordable, and knowledgable in what he does and old school customer service. I trust him very much. If I have to call AAA 99.9% of the time Jj's will be the destination. He's helped out from tires, to electrical to engine. He's even fixed my mom working electric Windows. Go to JJ for all your automotive needs. read more

Great customer service from George and they were very quick with my smog check. Would recommend.

Very time I gat an oil change or something else, I get the best service. Very honest company. JJ is awesome.

If I could give more than 5 stars I would! Outstanding service and customer service! JJ, the owner, is very helpful and generous with his time, he took the necessary measures to explain fully to me what was going on with car. He made sure that my problem was resolved and even followed up with me after the fact! I went in thinking I needed an alignment on my car because it shifted to the left. He explained that there was nothing wrong wth the alignment and that my tires were balding and that it was very dangerous to keep driving them in the condition they were in! You can tell that he takes pride in what he does and that he genuinely cares for you as a customer. If he could, he wouldn't charge you for certain services. He made sure I was completely satisfied before I left the shop! read more
