Walnut Creek Auto Repair

Good service and very nice! I would return if needed and definitely recommend!

My check engine light was on and I was terrified I was going to get a call with all sorts of things to fix. Turned out to be a faulty gas cap and they didn't even charge me for the labor. I'm new in town and was scared looking for a mechanic to trust. I will definitely return with anything else my car needs! Thanks for being an honest mechanic!

Good people, didn't try to take advantage of me. Timely.

Referred to by neighbor for a basic service. Well done, prompt, thorough, honest. I'm definitely moving my car maintenance/repair business to these folks.

The new owner, Jon, is very professional, helpful and friendly. My car drives smoothly after the repairs!

DIABLO AUTO is the place I have relied on for 10 years because service and price have always been outstanding. DIABLO AUTO recently acquired new owners and they have to my good fortune continued to operate at the same high standards and professionalism as before. I will definitely continue to trust DIABLO AUTO with my car as well as refer them to other people.

I talked to Jon and have my 2009 Lexus ES350 tolled to their shop. They changed the truck lock and I had my car back the next day. Very seamless. Highly recommend this place to others.

Excellent service. Diagnosed and repaired my Roadtrek van. Ready on time and in-line with the estimate provided, John explained what was done with very precise and easily understood terminology. I have used Diablo Auto Specialists for many years and will continue to do do,

Great shop. Upfront and honest! Did 30K service and new tires. No attempts to up-sell or do unnecessary work. Highly recommend!

Provide Dependable and honest services. Provide detailed information on the issues to address with alternatives. Will highly recommend their service.
