Walnut Creek Auto Repair

Tim is awesome. Had them replace an air conditioner over three years ago and it is still going strong. I recently called in because I am selling a car that stalled because of low idle. Tim asked if I recently replaced the battery, which I did, and told me my particular car takes time to relearn where to idle after replacing the battery so I should give it time and see if it resolves. I wanted the to check out the car anyways because I am selling the car and wanted piece of mind everything was running well. They confirmed it was just the idle resetting and gave me a price break. Got to appreciate the honesty! I took my other car in for brakes. This is my go to mechanic. Fair, honest, and great work that is much cheaper than paying dealer prices.

There was an issue and Tim called me to explain that the car had to stay overnight. I had something that evening and Tim offered to pay for my Uber considering the situation! Very good service and reliable place. Tim always explains things in simple terms and makes sure you know what is being charged.

Wonderful experience at Diablo Automotive. They are easy to find, the place is clean, they are efficient. Fixed up our car in good time for a reasonable price. What more can you ask for?!

I took my Miata in because of a clicking noise that seemed to be coming from a front wheel. They took apart the wheel and brakes looking for the cause, but, couldn’t find anything wrong. They put everything back together properly torqued and the noise was gone! They solved my problem for less than $100!

We were looking around for a place to fix our vehicle and came across Diablo Auto a couple weeks ago. We called and spoke with Tim who was very helpful with our car that hadn't been serviced in some. They gave the car a complete check up and phoned me the same day with their findings. We ended up needing s new battery and a refill on the air conditioner. We're super happy with the service we've experienced with Diablo and will be bringing our other cars in when they're due. I can't say enough about the importance of supporting small businesses, especially when they provide great customer service and take car of business. Please give this company a try!

Tim is an honest business owner, I’ve been trusting him with my Hondas and Toyotas for years. Always timely and professional, and upfront with what charges there will be.

They handled my specific problem with my truck and kept me informed throughout the repair process so I was not surprised when the bill came. It was a pleasure working with Tim.

I’ve been going to Diablo Automotive for years now! They are efficient, and provide excellent care and survive. Tim is a pleasure to talk too as well. Highly recommended.
