Great experience with Refined Auto Mobile Repair. Ceaser gave me a fair price to install my alternator and diagnose an oil leak, and didn't try to upsell anything. Everything was done quickly, efficiently, and professionally. Honest and reliable service. I highly recommend him.

Old Battery Terminal that Caesar tried to clean
Patrick N.

My car wouldn't start randomly one evening so I reached out to a bunch of auto repair companies on Yelp for quotes. Refined Auto Repair responded back within the evening quoting $50 for diagnosis and the diagnosis fee will go towards any repair cost if necessary and agreed on the same day. This was a far better deal than the 10 other shops I inquired for quotes (typically $100 for diagnosis fee or flat $350 fee for total repair). This is mobile only so be prepared to schedule a visit meaning it will take a a couple of days if they are busy. Caesar came over at 1pm on a Sunday. Immediately figured out it was a battery issue due to a weak start and the fact that my battery was 6 years old. We hashed out the details for the total repair cost which I was happy enough to take the deal. He mentioned the battery he will provide will have a 3 year warranty (I am going to quote this on 12/15/2024 in the future) and he will swap out the old battery for a new one if 3 years hasn't lapsed which should be easy because the battery was purchased under his account. He also mentioned his battery should last about it 5-6 years. He took out the old battery and tried cleaning the battery terminal which was eroded and hardened due to years of battery acid seeping in. As he was cleaning the terminal, I asked him details on how one can tell if the issue is the starter or the battery and he explained that if it was the starter, the car wouldn't start at all but mine had a weak start instead. After 10 minutes of attempting to clean it, it was concluded that the battery acid had hardened the terminal to the point where the latches wouldn't release so he replaced the battery terminal with a new one free of charge and then he went off to purchase my new battery. Caesar came back within 20 months and the new battery was replaced and the car was up and running smoothly. The whole ordeal took about an hour. Zelle was the preferred payment method. Caesar mentioned he also does variety of other things such as oil change, etc so I had him check my oil and it was fine. I will definitely be reaching out to Caesar in the future for my auto repair needs. Update: After the battery replacement, my car still ran into problems although a weak start was no longer the issue. What ended up happening was that the engine would rumble when idling and there would be a delay in acceleration after stopping the car at stop signs and even turned off occasionally. Caesar came by two more times to diagnosis the issue over the span of two weeks and he was able to clean the throttle body which finally fixed the issue! I had some doubts at first but Caesar came through. Apparently the throttle body had too much gunk in it which prevent enough air flow into the car. I am very happy with the results.

Extracted spark plug.
Neil D.

Called last minute because when I was replacing my spark plug, the old one snapped off. It needed to be extracted out of the car. Caesar was able to extract the old spark plug and finished the spark plug replacement. He was able to squeeze me in same day. He was very professional and the price is very reasonable. Would recommended giving him a call for any mobile mechanic needs.

I've been coming here for the past year, and the service is honestly amazing. I even called my dad…read moreto tell him how insanely fast they got me in and out. I joked that this place feels like a "fake mechanic shop in disguise" because of how efficient they are. George, the owner, is incredible. He answers his phone within two rings, never says no, and always finds a solution to any car issue. He's transparent, reliable, and truly prioritizes his work ethic over money. They always get me in and out within minutes. Before moving to Long Beach, I only went to the dealership for any car problems. Once I moved, I wanted something more convenient and now I'll never go back to a dealership again. Today I went in for a service, and George let me know my tires weren't looking good. I told him I agreed (they were long overdue for a change), and he immediately connected me with his friend down the street. I ended up getting brand-new tires for an amazing price, the deal was so good it almost felt unreal. Once again, it was all thanks to George and his connections. As a woman, it means a lot that he doesn't try to exploit my lack of car knowledge. Instead, he educates me and treats me with respect. Even after moving to Santa Clarita, I'll continue coming back because no one compares to George and the service here. Im a forever customer. Thank you George and your team! Highly recommend!

However, I couldn't give 5 stars because the shop layout itself was a bit disappointing. It looked like only one or two cars could realistically be serviced at a time, which made the operation seem limited. Additionally, the person who initially came out to help didn't appear very knowledgeable and didn't seem like he had the authority to make decisions on behalf of the company. It's good to know this business is around and available in the area, but based on my experience I probably won't be returning here for service.

I found Francis through an online search because of the many positive reviews, and during our first interaction he was friendly, professional, and seemed very knowledgeable. He ordered the part directly from Acura and quoted me a fair price. My car was ready the following day, but when I arrived to pick it up, Francis informed me that my vehicle had been involved in an accident while in his care. He explained that another driver had been speeding through the parking lot and crashed into him. He gave me the other driver's information, and I contacted him immediately. The other driver gave a very different version of events. He stated that he was backing out of a parking space and did not see Francis. He also told me that Francis provided his driver's license information but refused to share insurance information. Now, more than a month later, I still have a damaged vehicle and have not received insurance information from Francis despite multiple phone calls, text messages, and outreach from Mercury Insurance. I trusted this shop to take care of my car, not return it to me in worse condition and leave me responsible for a $500 deductible. What has been most disappointing is the lack of accountability and urgency. Francis acted as though this situation was not a major concern and repeatedly assured me that the other driver would "take care of it," which has not happened. According to the other driver, Francis even asked him to change the story about what happened. I chose this business because of its strong reviews and the image Francis presents, but my experience has been extremely stressful and disappointing. I believe customers deserve honesty, transparency, and responsibility when their vehicle is in someone else's care.
