Tien was on time, even early, and fixed the problem very fast. He checked the car and made recommendations on items to fix, without putting any pressure. The whole experience was nice and convenient.

This was the second time I've worked with Tien and I am happy as ever. I am going to have him look at my other car, and continue having him manage the care and maintenance of both of my somewhat finicky, somewhat old, European cars. He is thorough. Communicative. Flexible. Patient. Honest. And direct. I myself work on cars and know enough to recognize when someone does or does not know what they are doing. This guy most definitely does. Don't let his laid back, reserved manner confuse the issue. A skilled, experienced, grounded and forthcoming professional.

Booked Tien 3 times for troubleshooting misfire on engine. He is always on time and provides explanation for everything you ask. Very honest with the answers and will not sugar coat things if he finds a problem. We ended up fixing idle issues, intake leaks, coolant leaks, and did a timing belt/water pump replacement. In summary, you will want to book him for your next appointment if you booked him your first time.

He came even earlier than expected. Though O'Reilly got him a wrong part (oil filter) but he drove to pick up and came back and finished the job on time. He also let me know what's recommended

Thank You Tien For Getting My Baby Back On The Road. Your Super Efficient And Hard Working.... Keep Up The Great Work And I Most Definitely Will Be Using You For Services In The Future

Tien was awesome! I booked for a throttle body to be cleaned and replaced transmission fluid after my first appointment said that might be the problem to why my car isn't starting. Found out that one small, rubber thing (size of a thumb) was stuck between the throttle body opening. Picked apart my car to get the intake manifold gasket out because the rubber went inside there. He was determined to get it out and he did. Also, took out my tpms that has been on forever. Overall, great experience with him. Would book him again.



on September 13

Tien notified me that he was running late and when he arrived he immediately worked on the car. He replaced my thermostat, drained the oil and change the oil filter, replaced the oil drain plug and replaced my expansion tank and removed the valve cover to replace the valve cover gasket. We are missing the expansion tank hose. Tien ordered upper radiator and lower radiator hose and asked me schedule another appointment. I scheduled my next appointment hoping all the parts are here next time so Tien can complete the valve cover gasket and continue to troubleshoot the cooling system.

on September 02

Tien has consistently been prompt, courteous and professional in the several services on my three autos. No problem asking him to come back when the cars need service again.

Tien called and asked if he could come earlier than the appointment, I said yes and he came then. He got the work done with changing the starter and I am happy that our car will now start.

Tien was on time and got right to the heart of the problem with no mesing around. I'll be calling him back for sure.


  • Car Inspection


on September 13

Initially I was quoted $189.95 which includes the engine inspection and cooling system flush. But when Tien arrived and seen the engine, since the expansion tank and expansion tank hose is broken he can't do the cooling system flush. He only did the engine inspection and charge me only $80.00 for the engine inspection and he ordered all the parts and instructed me to get another appointment to replace the oil, replace the expansion tank and expansion tank hose, the oil drain nut and the valve cover gasket.

Tien was a godsend. I had researched an issue with my TB and was confident in my conclusion of parts to be repaired. I wanted it to be anything but the transmission. I had taken it to a mechanic previously that only pulled 1 code for me and gave a vague diagnosis: "well, it SOUNDS like transmission." I wanted it to be anything but tranny of course. Tien was scheduled for replacement and services for various things I believed the problem to be, but when he came for the appointment (delightfully early I may add), he started first by investigating my claims and showing me why it would be a waste to replace those parts. He pulled 2 codes for me and we test-drove together and he showed me the 3rd gear was slipping. He gave me crucial advice and information and saved me hundreds if not thousands of dollars of work with his honesty and demonstration. I can't express how grateful I am that Tien was there to work with me that day. When I've traded in my car for a new one, I am sure I will be calling on Tien for all of my routine checkup needs. =)

on August 25

Tien was scheduled to come over at 5:30 but called me around 11 to say he could come earlier, which worked out. Glad he could come earlier. He was very nice and professional. Would use him again.

on August 14

I made an appt. for Tien to come by and replace the fuel pump for my no start diagnosed by him through the inspection I had a few weeks earlier. Tien got to work on the car immediately on arrival. As in many if not all jobs, it turned out to be a more complicated than expected. In the process of changing the fuel pump, he discovered that the new fuel pump was slightly different than the one being replaced and the wiring would need to be adjusted somehow to be able to use the new one. It was amazing to see as he used his knowlege and experience to make the necessary adjustments to make the part work! He could have taken the "shortcut way" which a lot of mechanics would have done. When he removed the old fuel pump, it seems that only the fuel hose part was damaged beyond repair, but the rest of the unit was intact and probably still working. He could have maybe just changed the hose part and left the rest of the old unit as is, but decided to replace the whole unit if he could, pending the wiring adjustment mentioned above. Thanks Tien for a great job highly recommend you to everyone!

Tien was very professional and helpful in fixing a job a bad mechanic messed up was very quick and efficient.

Tien arrived slightly early (which works well for us) for an appointment I set up for my mother's car. Very professional and he did a great job. If needed we would use Tien again!



on October 03

This is my fourth appointment for the same job - to check my service engine soon light and general cooling system. First appointment he did not have the parts and I understand and gave him a five star review. Second appointment, wrong part and missing some parts, he was able to remove everything but left he did not even put my oil, gave him another five star review. Third appointment was able to fix some parts but still left without finishing, I did not give him a review this time. This is his fourth and last appointment, he finally put my oil, he did a pressure test for the radiator and cooling system, reset my service engine soon light and left without drive test. At the end of the job I got a pair of bolt and nut and he said he found it at the bottom of my car. My plastic cover that covers the spark plugs was broken due to over-tigthening of the bolt and when I asked him why he said the washer portion was missing. He left my garage with leaked oil and coolant, I had to cover everything with newspaper and did the clean up myself.

on August 06

Arrived on time. Kept in touch. Finished on time. Great service. Second time Tien is working on my car. Will be asking for him next time as well.

Very friendly and knowledgeable; encouraged me to perform simple repairs/replacements myself instead of making me feel like I wouldn't understand my car, and that a mechanic should do every little thing (and charge a lot for easy work). I was very impressed that he went to purchase a tool that he did not have, instead of using a substitute tool that may have caused damage to my car.

on March 17

Tien was great. He listened to what I had to say as far as the symptoms the car was having, rather than shut me out like other mechanics will do. He was very knowledgable and explained very well his diagnostic and most importantly he was able to figure out the issue when other mechanics could not figure it out. I would definitely recommend him!

Tien went over and above in finding and correcting a problem with the backup camera in my motor home. He was professional, helpful in finding an alternate solution to the problem and competent in his work.

on September 30

Tien was SO WONDERFUL! He was personable and quick. I was left with such a wonderful impression of Your Mechanic and what they offer. My coworkers also got to see how the service works and how wonderful Tien was and will be using you in the future. THANK YOU TIEN!



Hyundai Sonata

Tien called me 30 minutes ahead of the appointment to let me know he is on his way. I needed the factory recommended 60,000 mile service and this included changing the serpentine belt. He inspected the belt and because it was in great shape recommended that I didn't need to change it right away. He called YourMechanic and updated my quote and saved me over $100 from the quoted price. He came prepared with a new Serpentine belt and just took it back with him. He took pictures of the old and new parts that he installed (cabin air filter, oil filter etc) and uploaded them to your mechanic so I had access to it. He also gave recommendations on what to watch for and how I can maximize life out of my car. Highly recommend.

on August 21

I enjoyed my first experience with MyMechanic. Tien came to my workplace, worked very quickly, was very respectful, and gave me a through inspection. I will definitely be using him again.

on August 19

Tien was running late from a prior job. He kept me informed on when he would arrive. Did the job and gave me good advice on my and what to keep an eye on. Will work with him again.

on July 31

Tien was very professional. He sent me a text 15 minutes before our appointment to let me know he was coming. He arrived on time, worked quickly and had me feeling very confident about his ability to diagnose my problem.

on August 13

Tien was called out for the same codes being on as last time. He ran a thorough check and found an exhaust leak.he fixed the leak free of charge in an effort to try and clear the codes.

on April 07

Although I wasn't there to oversee the requested work to my vehicle, the points leading up to it were exactly what I expected. Tien gave me a phone call about his arrival as well as possible times if i chose them. (someone had cancelled their appointment prior to mine, which worked out to my benefit.) My car's oil change is in tip top shape as well as my tire rotation. Thanks!

Town was prompt, courteous, professional, and knowledgable. I was skeptical that I could receive reliable, guaranteed service from a mobile mechanic. I'm still not sure how they did it. I wish everything in life was this easy. Thanks for a great experience.
