Absolutely outstanding! Jason accurately and quickly diagnosed the problem with my car, picked up the part for me, installed it, made sure it fixed everything, and it did! I couldn’t be more happy with the service. Highly recommended. Five stars*****

I was pleasantly satisfied with Your Mechanic;Jason was professional, courteous, knowledgeable and articulate. Jason took the time to explain the process about the repair, what his analysis found and suggested course of action. The original recommended repair was found to be unnecessary but substituted with a less expensive repair. The safety inspection uncovered another area of concern for future consideration in the near future. Overall, we are satisfied and will consider Your Mechanic again. Thank you

Jason is the best mechanic I have ever had work on my car. He is friendly, professional and very knowledgeable. I will always use him for my all my repair needs.

Jason is one of the best mechanics this company has to offer he came and changed the crankshaft position sensor on my bmw750li he was fast efficient and knowledgeable he did a full scan of my onboard computer and told me everything that was rong with my car along with preventative maintenance tips highly recommend Jason to do your work

Booked an appointment with Jason for my wife’s car since it was running rough at idle. I thought I needed new spark plugs and was quoted $372 for the job, which I agreed to. After inspecting the car Jason informed us the the plugs were good but the problem was a bad PVC hose or sensor. To make a long story short, the price was reduced to $132 since we only paid for the diagnostic and parts. Was very pleasantly surprised and happy at the amount of money we saved from not having unnecessary repairs done. Would highly recommend Jason to anyone needing work done on their vehicle. He’s honest, friendly and very knowledgeable.

My second time with Jason. Same high level of service. Very conscientious. Doesn't just "work on your car" but has researched you problem and offers thoughtful opinions and options. I'm pleased to have found a trusted mechanic paired with a brilliant, convenient service! I'll be asking for him again for future needs. And now my wife wants to begin using this service for maintenance on her car as well.

Jason is one of the best mechanics I’ve had on staff! His attention to detail & customer service is exceptional & second to none! Would highly recommend!

Hyundai Sonata

on December 04

Jason is very friendly, efficient and knowledgeable. He was prompt, (even a few minutes early). After replacing my starter, showed me exactly what was wrong with the old one. I asked about a couple more service jobs I wanted to consider. He explained them and sent quotes. Excellent service! I would like Jason back for future work.



Saturn Vue

on November 29

Jason was excellent and very informative. He arrived on time had a discussion on the issue of the vehicle and he said no problem and took over from there. He was done in no time and even went out of his way to alert to me of future maintenance items I should keep an eye on that he noticed while working. I will definitely request him again for future work.



Toyota Camry

on December 19

Very nice and professional. Blew my mind. As the old military saying: went beyond his call of duty. Can definitely be trusted

on November 07

Jason can do the work very quick. The knowledge he has as a mechanic is very insightful. It's good to know what cars use in their technologies and Jason will tell you what's happening. He cares about the service being worked on and I would recommend most customers to give him a call with YourMechanic. He noticed a crack in my reservoir when I bought a used car. I had some JB weld and he put on a couple coats after using a tool to find the damage. Nobody wants to run into an extra problem like that. So that's a real good guy. Thanks!



Dodge Charger

Jason did a wonderful job diagnosing the problem I was having. He went above and beyond my expectations.



Lexus ES300

on May 02

Jason was great! Very knowledgeable and experienced. He provided very good suggestions and information regarding my car. I will definitely use and recommend him for any future work on my car and other referrals.

on April 07

Jason was very knowledgeable and deliberate. He did an inspection to verify the complicated problem and the proceeded to acquire the OEM part required and credited me the inspection fee as he completed the repair. I would highly recommend Jason on all types of repairs and service.

Toyota Sienna

on August 31

This was a pleasant YourMechanic experience, with Jason C. doing the job for my toyota sienna. He is honest and reasonable, recommending what is best for your car according to its situation. Instead of just doing the work order which if unnecessary will be a waste of money, he did preliminary inspection and validated what actual work is (or may be) needed. The problem with my car's VSC was kind of tricky, but he spent extra time to figure it out and get solved. Awesome job!



Dodge Neon

on November 10

Jason was on time and very friendly . He was very thorough showed me everything under the hood , he let me know what else i needed to have fixed on my car. He made sure everything was put back together and cleaned before he left.

on July 17

I am extremely impressed with MyMechanic and Jason. I am driving to Tahoe this weekend and Jason assured me that all is in good working order...just need to put air in the tire!! Once I am back from Tahoe, I will definitely recommend your service! Best of luck!

on July 26

Jason was great, he actually took off $200 from our estimate as some of at any dealership, they would have found ways to charge unlimited $ more and still not be fully done.. these guys are just good, the car stays at your house, you know they are working on nothing but your vehicle and they explain everything in "plain english"...



Honda Civic

on August 02

Jason Certeza is probably one of the best if not the best professional mechanic I've met. He's honest, thorough, communicates well. He fixed and went beyond to explain/answer patiently all my questions. He's one of a kind, and he does not take advantage of the customer's ignorance. Thanks for sending him to fix my son's Honda Civic. You've gained a customer for life.To YourMechanic, please put on the website that he's ASE Certified....thanks again

on November 01

Jason did an excellent job on my 2007 Pacifica for oil change, coolant flush, thermostat and radiator cap replacement. He kept my garage and driveway clean.

on October 21

Great mechanic. Very thorough and knowledgable about how circuits work and sensors systems. He explained everything that was going on with my car and only replaced the parts that were actually needed. Very happy with a job well done. Highly recommend!

on October 19

Jason was professional, curtious, and did an amazing job. I feel he went over and above what I request him to do. I will request Jason anytime I need an honest mechanic.

Ford Expedition

on September 23

This is the 2nd time I've tried Your Mechanic and so far I have been very pleased. Jason was very thorough and took the time to explain everything to me and help where needed. He updated me to what I may need next and to keep on eye on it. No pressure and very accommodating. Spoke about issues on our other car and will be looking to now have that serviced through this company too. Jason was extremely helpful. Enjoyed this service!

on November 06

I'm fairly unfamiliar in the area of car repair and this was my first time with yourmechanic. I got Jason, who did a great job in explaining what to look for and where my car might be having issues. He did a terrific job in the oil and filter change and servicing and I couldn't be more satisfied!



Chevrolet Lumina

on November 12

Most mechanics would just install the starter I provided. Jason took the time to test the starter in my car and explained how it all woks. He did the job effortlessly, at night, with a flashlight in his hand! I will definitely recommend Jason to my friends and family.

on February 02

Jason was great to work with. He explained everything and showed me what he was working on. Great communication and very knowledgeable. I will be requesting Jason again to do future work.

on October 04

Jason it great. He isn't bothered when I ask my many questions, trying to understand the repairs (so I don't get ripped off). He makes sure to put down a tarp so that fluids don't spill in my driveway. Not all their mechanics do that.
