Are you looking for an honest mechanic who doesn't try and sell you on unnecessary work? Then you found your guy!! I started coming to JR last year when I was having issues with my truck. He remedied every issue that I have had since. On top of that he has done all the typical maintenance at a fair price. He is a one-man show, but still manages to get you your vehicle back in good time. Do yourself and your vehicle a favor and make JR your main Mechanic!!! read more

Jason and his work is top tier! He deserves all the blessings. And this review is way over due. My husband has been going to him for something like 20 years. I myself the last 9ish years. He's straight forward and transparent. His knowledge is masterclass. And he fixes whatever it is right the first time. Thank you Jason, we appreciate you! read more

Outstanding customer service. Just got of a lengthy call where the guy knew it likely didn't make mathematical sense to repair my older Tacoma. He was upfront and honest about costs vs final vehicle value. Insight I'd never expect. When the time comes for work on other vehicles, I'm looking forward to getting back in touch. read more

Jason was incredible; he saw the radiator leak I had, got the part within an hour, and replaced it without having to wait long! He also noted the part of my car I said was loud, and he encouraged that it wasn't a necessary fix. He understands cars well and I highly recommend as a trustworthy servicer! read more

Straight to the point and also went above because I went in for one service and they saw my tire pressure on and they are ahead and just fixed for me read more

Jason was awesome. I took my car for new brake pads and was able to schedule an appointment quickly and the price was very reasonable. My car was ready when he told it would be. I would definitely recommend him. read more

Come here regularly for car service. Jason is always giving me the best service. 10/10 recommend!

Jason is a good man. I had gone to another mechanic the day before after my car broke down. I had driven barely 2 miles after I had left the other mechanic and my car broke down again - turns out they had missed diagnosing an ignition coil! Jason identified the problem quickly, and what I liked in particular was that he showed me the engine and the faulty cylinder and took the time to explain what needed to be done. Made a car novice quickly and easily understand what the diagnosis was and why it made sense to get that course of repair. For just the "bedside manner" alone and the patience that he showed, I'd happily recommend Jason for your autocare needs. His pricing is not necessarily the cheapest in the area, but he is honest about telling you what you need (and more importantly, what you don't need), does quality work and in my case, went above and beyond that it was well worth what I paid. read more

I was referred to Jason by my neighbor and I am so thankful I finally have a mechanic that I can trust. He's knowledgeable and won't over charge you. He won't recommend any extra services that most if not all others take advantage of. Guys like this are rare nowadays read more

Had my 2006 Honda Civic serviced here. 4 motor mounts and a powering steering pump later, I can literally feel the improvements. Jason is professional and willing to communicate. Great experience highly recommended, will visit again. read more

I take my cars to Jason for all my car maintenance and repairs. He always gets the job done and has the best price. Definitely your go to!

It's so hard to find an honest, trustworthy and professional person but that's exactly what JR Auto care has with Jason. I called about my Volvo S80 because it was leaking fluid from the thermostat housing. He worked me in at a time that was convenient for me and he took care of everything! He let me know the cost up front and that's exactly what I paid when I picked up my car. It runs great now and he even had the parts he replaced in a bag in case I wanted to inspect the replaced parts. If you need your car repaired don't hesitate and take it to him first ! You will not be disappointed ! I'm sending all my family and friends to Jason ! read more

Trustworthy mechanics. Jason diagnosed my car and informed me I only needed a new gas cap. Whereas the Dealership wanted more money to do further diagnosis. He got my car in and out in a reasonable amount of time and on short notice. read more

I can't say enough about how awesome it is working with these guys!! I've been coming for years (from first location to this one) & will always be willing to make the commute because they are the most honest people & provide above great service! I just came to get my brakes & oil done. Jason told me I have plenty of pad on my brakes to ride it out a bit longer & get my moneys worth out of them. I was prepared to pay so this was a nice surprise. It's so nice to have fair, ethical people in business because I know there are plenty of places out there that would've taken my money, no problem.

I've been following Jason for about 11 years now and into his 2nd shop. He knows his cars in and out. He takes care of my 2009 Nissan and 2006 Sienna.

I am going to start off by saying thank you Yelp for helping me find this place. Sometimes it's hard to trust reviews especially when they have 5 stars. "Like is this to good to be true" "should I believe the hype?!" Well I can honestly say this was my first time bringing my vehicle to this location and my first time meeting Jason. My Jeep Wranglers check engine light was on and my Jeep was leaking oil. I had gotten a transmission flush a few months back (Walnut area) and the place I normally take it to told me it was leaking transmission oil and that I needed to make an appointment for a mechanic. I told my husband I wanted a second opinion and I wanted something local to home. This is when I looked and found this place. I spoke to Jason briefly and set up an appointment to come in Thursday at 9am. When I showed up Jason checked the car and knew right away what was causing the leak and told us the car would be ready the same day. When he called me about the car being ready he told us the Jeeps Thermostat wasn't registering the proper temperature of the car and check engine light keeps marking something is wrong and we would have to replace it soon. We asked him how much more it would be and we were blown away how reasonable and what a deal both of the repairs were. We were both pleased with Jason's communication and customer skills. He's very knowledgeable and his prices are fair. We will no longer commute to Walnut. Jason has gained new loyal customers. Thanks Jason you're awesome. read more

Jason used to be in upland but opened up his own shop here. Best work hands down. Honest, fast, and more importantly trustworthy. HIGHLY RECOMMENDED. Thanks for all the awesome work you do for all the cars I bring here. read more

I had a different mechanic for years and then I got married. Thank God I don't have to deal with my car anymore. You get married and become one, so I gave up my mechanic for Jason. What a great guy.
