I had Jay come do a Prepurchase Inspection for a 2007 Toyota Tundra at Premier Motors in Hayward. The cost was $240 and he showed up at the time he agreed upon. He was very thorough, did a computer check, thorough check under the truck and on the engine, and test drive, and was able to see that a light had been replaced, rust had been painted over, a previous accident/damage had occurred that was not on the CarFax, the rear differentials were leaking and needed replacement, and there were some small leaks in the engine as well that would require future repair as well (along with other smaller things). There was at least $2500 worth of work that would have to be done to be safe to tow immediately and about $4000 total of work within a year. He thought the truck was overpriced at $17,900 with the fixes needed. I tried to negotiate the price for these fixes and the dealer would not budge a single cent. They were obviously not used to a mechanic checking out their trucks. He saved me $4000 worth of fixes on an overpriced truck so walked away. Very honest guy and highly recommend. read more

Jay looked at my Honda MiniVan and just by looking at the engine and the description of symptoms verbal and real display, he was able to tell me the problem(s) I've in the car. BTW this was free inspection/estimate at my house driveway. I didn't have to go anywhere. I've a fair idea of what are the problems - Jay explained it in detail. I would highly recommend Jay for car related problems. I am deciding what to do now that I know full extent of the problem(s) and the fact that its an 17 year old minivan with close to 200k miles. But (I am hopeful), if decide to get it fixed, it will be Jay who would get my business. read more

Jay is legitimate as they come. Knowledgeable, articulated exactly what work needs to be done and most important - he was honest! Highly recommend this gentleman's services read more

I was interested in a Dodge Durango with a V8 at a local Fremont dealer, but wanted to get a mechanic's opinion before making a final decision. This is how quickly Jay came through: By Wednesday evening, Jay's responding (within hours) to my quote request for a PPI. Thursday afternoon, he meets me at the dealer lot ready to inspect. The generous value I received from his service: he's got a flashlight looking over the the engine to see wear and tear, he's under the car looking at wheel bearings, powertrain and showing me what he's seeing. While test driving, he's looking for suspension issues, listening for transmission shifting, testing brakes. Lastly, he's connecting a digital device to run codes and found a couple electrical issues that needed to be addressed. When he completed the inspection , I had an effective Due Bill to keep the dealer accountable to the needed repairs, had I gone forward with purchase. He also provided nuggets of wisdom on engine care and car maintenance that were helpful as well. Overall, Jays service was excellent; both effective and educational at once. Definitely recommend his auto expertise! read more

Jay, did the job expected he replaced the starter in my Lexus while parked in my stall. The price was fair and more convenient than having my car towed to a shop. This was memorial day also and I saved a day of inoperation because no one else was open! For this I am grateful. Mobile Mechanic is now on speed dial. read more

Had Jay come take a look at my Rx-8 that was cranking but not starting, he was able to give me a diagnosis within the first 10min. Gave me simple instructions to follow and I was able to get the car started later that day(deflooding). Will definetly use again if needed! read more

Had a stater issue with my car ..i assumed I needed a starter. Jay came put his quick charger on my car and it started. Then charged me $120 dollars for basically 3 seconds of work. Said he diagnosed it. No diagnosis was done. $120 for a quick charge. Wow ! read more

My car wouldn't start after a 2-year pandemic hiatus in the driveway. Made an appointment with Jay who kept me appraised of his arrival time as his previous appointment went over. Once on-site, he quickly verified that the battery was dead (not just discharged) and replaced it. Did a few other basic checks, told me how to clean up the fuel system and I was left with a working car. Two days later, he called to inform me that he was able to pull the warranty on my old battery and would refund me the cost, which he did. Bottom line: Efficient. No BS. Honest. Can't evaluate how he would handle a more complicated repair job, but I would not hesitate to try him for one. read more

I don't usually write reviews but after discovering Jay and Mobile Mechanic on Demand, I wanted to share my experience. My car didn't want to start and it was completely dead. I had no clue what was the problem. I had contacted three other mechanics before Jay and they didn't even know what they were looking at and couldn't tell me what the problem was. When I contacted Jay, he came over the next day to inspect my car. Right away he told me what was wrong and what needed to get replaced. The next morning he came over again and replace the fuse right away, not less than 15 minutes he was done. I want to thank him for solving the problem I had with my car and fixing it. What took a week and a half with that other mechanics, Jay did it in a span of minutes, and I salute that to him. If there's a mechanic I recommend in this area is Jay and Mobile Mechanic in Demand. The reasonable price, the professionalism and communication made everything easy for me. Now my car is running as ever before. Thank you again Jay! read more

I do not often provide a recommendation but when I do, it has to be rare and unique experience. I am very picky who I have working on my car. I am looking for a mechanic who I can build a long term relationship with because of their competency, integrity and their recognition of my needs and situation that might be different than other customers. I had such a relationship for two decades with a car mechanic in Fremont that recently sold his shop. The lead mechanic was still there so I decided to continue, at least for now. But I noticed the prices seemed higher. When I recently went back, they presented me a proposal for maintenance that were more than value of the car. What ever personal trusting relationship I had with them was now different. I knew I needed to make a change. I stumbled upon the concept of Mobile Mechanics, which I was unfamiliar with. Like most things I do, I did a deep and exhaustive dive into the pros and cons, Mobile Mechanics in my area, etc. Yes, it can take some time and diligence but if you are replacing a several decade relationship, it takes time, reflection, re-examination of needs and possibly some trail and error before you to discover the right fit for you. We live in a world today of more words with less true substance and a veneer of integrity so it might even take more time discovering a shop, a person, that can meet this type of relationship that I want and demand. Not easy in a world promising to solve all your problems and make your life easier. Often forgotten is under promising and over delivering! After weeks of searching the Mobile Mechanics industry, I stumbled upon Jay and Mobile Mechanic On Demand. My usual criteria was not first met by Jay. He was not a shop in the top 3 to 5 with the greatest number of positive reviews. But in Yelp, he was in the top 3 recommended in my area, which seem strange when he had only so few reviews compare to many others. I kept looking and speaking with others but I kept coming back to Jay. If you look at his reviews, the one clear theme that pops out in the first line of each review is how honest he is. A person who knows his current limitations and is brutally honest about them but also is clear what he can do is a rare quality today. But again, it is just written words and until I meet the person, engage them and experience for myself how they respond, that is the beginning of a possible life long relationship the enriches one's life. I want people around me who I can deeply trust and who knows me, even better than myself at times, to support me so I can put my time into utilizing my gifts and contribution to others ... and know the rest of my life is well taken care of! My time is the most precious thing I have and who I engage needs to honor that. After engaging Jay this past week and his detailed approach to my needs were met and exceeded at a very reasonable price, I can say without any reservation, Jay of Mobile Mechanic On Demand, in my opinion, is such a relationship! But don't believe me, just try him out once ... discover it for yourself ... and I think a new world may be open to you in how you and your car can be serviced. read more

This morning my car did not start. I kinda thought it was battery however the car was inside the garage so I could not jumpstart. Found mobile mechanic on demand in yelp but there was no rating no reviews. I called and he answered promptly and gave us the time. He came and diagnosed and sure enough it was the battery. He went to get portable battery then again went to get a new battery and changed right there and there. He also made recommendations based on the circumstances and that's actually would make sense. His charges were reasonable too. Very humble, friendly, dedicated, and service oriented was what I found gentleman of mobile on demand. He seemed to be very busy person but won't rush until work is done. I am glad I went with my hunch and got chance to work with him. I am very satisfied with the service and recommend him for any mobile auto service needs. read more

I have 20 year old lexus Gs 300 which would not accelerate and would not shift and loose RPM on th he dash board . Some other mechanics diagnosed as transmission and almost gave up on repair.

I'm glad I have my old buddy running great again . Thanks " DOCTOR" , car is running great read more

I was stuck at Walmart in Union City. My truck would crank, but wouldn't run. I suspected a fuel issue, but had no tools. I looked up Mobile Mechanic On Demand, and Jay came out. He also had no tools because someone had stolen the catalytic converter off his truck, so he couldn't drive it. He borrowed a rubber mallet from the Walmart tire shop, gave the fuel tank (where the fuel pump lives) a few whacks, and it started right up. I am forever in Jay's debt, and hope this review brings him many customers. Stand-up guy! Thanks Jay! (from Joe) read more

Met with Jay this morning. Very cool and knowledgeable mechanic. He came to my place and diagnosed my car. It was due to a malfunction with the car alarm and kill switch. Jay informed me what I needed to do but was unable to repair the issue so he referred me to Subaru to get a new key fob. Jay was honest and never tried upscale me. He didn't charge me anything and told me to call him if the issue isn't fixed. I will definitely contact Mobile Mechanic for all of my future car needs. Thank you again! read more

Extremely honest. It's refreshing to meet a mechanic that has down to earth wholesome kindest for his fellow man. You can genuinely tell he cares about his customers. Will definitely use again in the future. read more

Honest and straight with you. No bs, will use this service again. Came by, hold me the problem and told me what I needed or not needed to do. Thank you read more

Very happy with the service - honest, experienced, and tried to respond ASAP ! I recommend J to all my friends for the help in need! My first experience with Mobile mechanics for on site auto battery replacement- but surely a good one that I am comfortable with confidence! read more

Jay is the most honest, kind, and knowledgable mechanic, I have ever seen. Extremely polite and very reasonable charges. Car wasn't starting, battery was new. He jump started and found no issues. He explained to me, what issues might be if car is not starting and inspected car, he fixed signals on dashboard. It was a quick visit. He didn't sell me anything in fact I asked him to replace few things and he said I didn't have to because my car was not very old. Thank God, I called him else I was going to tow my car to some other service station. It spared me towing charges. He will be my go-to-guy for every car issues in future and I will recommend him to every and anyone who seeks me for reference of any mechanic. I don't know why he doesn't have many more reviews. Good people like him deserve more reviews and business. Thank you Jay, for helping me! read more

Great mechanic. Very honest. He is very responsive and best of all he comes to your house!

Wonderful customer service and superior car repair. Jay is always there either for an emergency or routine car maintenance. Thank you for all your help! read more

I can't say enough nice things about Jay. He was professional and on the level. Might be the most honest mechanic I've met.

Mobile Mechanic came and gave me an honest diagnosis as well as a reasonable cost on repair. Unfortunately I've decided to part ways with this old van since I have spent too much money already on repairs. Thanks for your prompt service Mobile Mechanic! I will keep you in mind for other future work. read more
