Diagnostics and Warning Light Issues service at Master Mechanics and Smog

Diagnostics and Warning Light Issues

Modern vehicles communicate problems through signals, not explanations. A check engine light, oil light, or system warning does not tell you exactly what is wrong. It only tells you where to start looking. That is why proper diagnosis matters.

Our Clients Say

Client's Testimonials

Highly recommend this place! I made an appointment for a smog test. When I arrived, they checked my document and told me I actually don't need a smog test this year. They were very honest and friendly. They saved me money and took the time to explain everything. I really appreciate their honesty. I will definitely come back here for my smog test next year.

I hate getting smog checks. I practically get at least one every year since I have multiple cars. Usually I look online and see what's the going rates. It ranges from about $31.75 to over $50 plus $8.25 for the certificate.

Toro A.

Bobby responded within five minutes of me posting my project on Yelp. He offered a $40 smog check with a DMV certificate and accepts credit cards, better than any other quote I received in the area. I then stopped by the shop, and he had everything done in just 15 minutes. Really appreciate the quick and efficient service!

Lufei R.

Sunnyvale, CA

Bobby is very clear and steady in the work. He made his estimates very reasonable and delivered fixes predictably. He pointed out that my car would need more edits sooner to follow and even gave me a discount on the parts. He fixed the smoothness of the ride for free. He made the car as good as it was a couple of years ago. Definitely a very reliable person who loves his job. Overall it was a great experience.

Manas B.

Service was very prompt, friendly and fast. Cannot beat the flat rate as quoted. Location is convenient as well. I plan to share my fine experience with family and friends. I appreciate great service with a smile.
