It's also within walking distance of my house so I don't have to pay for an Uber/wait for a ride when I drop or pick my car back up. I've had an oil change done here, a front headlight replaced, and they fixed a recurring issue I was having w/my blind spot detection system and key fob -- the latter something my prior mechanic was not able to fix for some reason. The blind spot detection system error light did come back on after about a week, but I think it requires more than just resetting the code/calibrating. I will just live w/that for now. The only demerit I would give is for when your car is ready. Each time I've dropped off, I've been told the shop would call me when they had an update or when the work was fixed (expecting 2 calls), but I never got any calls each visit -- I had to physically call and usually had to leave a voicemail which was not always returned. They are pretty busy so I get it, but you would think they'd want to call you to get your car out of there to clear up the queue when it was done. The last time I went -- I had initially dropped my car off around 8:15am or so and didn't hear back around 3:45pm yet (was told to expect an update around 11-12p) -- so I was forced to walk there, not knowing if my car was ready or not, and after waiting awhile found out my car was ready. It still took another 20-25 minutes to get my bill, pay, and get the car brought up to me based on the size of the lot and the amount of cars that are in that lot (every mechanic seems to have tons of cars in their lot that are not driveable taking up a ton of real estate on premises). It started to rain too and the waiting area itself is quite small inside -- I ended up waiting outside under an awning for my car. They didn't seem to be in any rush to get my vehicle out -- not sure if it was just too busy that day or they are just not that assertive with check out procedures. It'd be nice if even if they didn't call you w/an update, that they'd at least call you when the car was ready and then got you ready to check out fairly quickly, especially if they'd had the car for around 6-7 hours for not incredibly comprehensive service. I will continue to go, but will expect to have to proactively show up towards the end of the day and hope I can get my vehicle out in a reasonable amount of time. Otherwise, they do very solid and affordable work.

I took my car to Juan for analysis on my transmission. I had read online that some of the Nissan Muranos have had CVD transmission issues. I make sure I have all preventative maintenance on my car. I left my car for Juan to take it for a test drive expecting the usual diagnostic tool but instead he left with a TouchPad device. The TouchPad device detected issues & showed the error codes with my transmission. Juan updated me that the transmission would need to be replaced with a transmission from Nissan dealer. Juan then called the extended warranty company, faxed them the computer diagnostic findings & had everything authorized in record time. There was a 2 - 3 week back order on the transmission, I took the car back home & as soon as the transmission came in Juan called me to bring the car in. Juan explained the process & timeline which he met as discussed. Juan had me bring my car back in a week later to check everything. I am happy to say that my car drives like when I bought her & I am so relieved that I found Juan at J & J Auto in Union City! Juan is an excellent mechanic & his diagnostic tool is superior to any device I have seen! I highly recommend Juan & will continue to take my car to him for excellent Customer Service & mechanical expertise!

As previously promised, I have continued to bring my cars and my family's cars to Ramon. I'll be…read morehonest--it has been a love-hate relationship for us. He does a great job with the cars, but sometimes the prices seem crazy. I will talk about two different situations. 1. I took my 2001 Toyota Camry to him about a year ago for an overheating issue. He diagnosed it as the radiator and quoted us over our budget. My husband decided to change the radiator himself, so we paid for the diagnosis--about $140--and took our car home. My husband successfully changed the radiator, but the problem was not fixed. We took it back to Ramon, and now he was saying it was the water pump or something else--I forget. I asked him if the $140 would go toward the service, and he said no because the $140 was for the radiator diagnosis. I was obviously upset, but we had no choice but to pay $200+ more to fix the problem. Long story short, that did not fix the problem either. Six months later, we needed to change something else. I told myself I would not go back to him, but my mother-in-law and mom have been to him and trust him. 2. I did, in fact, come back to him after getting a quote from Pep Boys for new struts (all 4) of $2,300+. Ramon quoted me over the phone for OEM replacement at $1,350+ tax. Obviously a better deal. Once we got there and he saw the car, he showed me how my brakes were paper thin, so we added that service too. He did an amazing job on my 2015 Honda Accord--it is driving better than ever! When I went to pick it up, he made sure to do a test drive. He felt something was still off and made sure I didn't drive off with any more issues. Had my car running amazing only 24 hours after dropping it off. After years of back and forth, this last time he proved to me that he does a great job. We will continue to trust Ramon with our vehicles.

I hate trying to find honest car spots for my car needs. I came all the way from Livermore because he said this place was worth it. Well, he was not wrong! It only took a little less than 2hrs for me to get a set of new tires and an alignment. The environment is comfortable and all of the staff I interacted with is so kind! They didn't mind that I set up my "office" in their waiting room so I can work while they did the job. There were some senior citizens waiting and the staff showed them so much respect and kneeled down to speak with them to show they were not just "customers" but, they are there to take care of them. That touched my heart. After my car was done, I was told that I get free tore rotations and that they can also do an oil change at the same time as it is recommended to do both at once to keep everything top notch. I will FOR SURE make the drive to Hayward to do that every 3,000 miles! If you need a reliable, honest, & quick place for your tire/car needs, this is the place!
