Walnut Creek Auto Repair

Jon took excellent care of my car and I found that he exhibited competence and knowledge in doing the necessary repairs.

I have three cars I have serviced here. Excellent work always.

Had a great first experience at Diablo Auto based a referral from a friend. Easy drop off, and after they assessed my vehicle, provided a detailed report of what needed to be done and some things to keep an eye on in the future. They provided an easy way to pay online and the car runs great!

I’d been going to Diablo Auto Specialists the past couple years and had really good experiences when Jon was running things. We had 4 cars we took there and always had confidence in the work. Jon’s gone and I’m stunned with the change in service now. They don’t offer an online list out of items inspected including pictures showing what they’ve found, and recommendations for work needing to be done. They don’t text you with an estimate. They don’t call if you need something replaced; you find out only after you show up. The customer service is gone. But it’s worse than that. But what really shocked me up was opening up the hood of my car to add some washer fluid only to notice the air filter housing was still unclipped, which seemed negligent. But opening the housing I discovered the air filter was missing entirely! They serviced my car 5000 miles ago and my car didn’t have an air filter put in. I was just planning on taking it in for service but it won’t be with them now. I’m livid! I’m done with Diablo Auto Specialists, or Autoworx or whatever name change is going on there. I would never go back and would highly discourage anyone else from going there.

We took our Toyota Prius in earlier this year to have an inverter replaced and other problems looked at. After a thorough diagnosis, we had simple electrical problem fixed that had vexed us. We also had an oil change performed. John and the staff at Diablo took care of us and the estimate and cost for us was incredibly reasonable. We ended up recommending a friend to their shop in Albany. I highly recommend Diablo Auto Specialists.

Our Mazda CX5 overheated on a hot day so we towed it to Diablo Auto specialists. After thorough evaluation of the car and not finding an issue, Jon called me to say the car was good to go....and didn't charge me for his time and expertise! He also did a great job fixing my rotors and brakes. I am so grateful to have a trustworthy auto mechanic!! Highly recommend Jon and his staff.

I had brakes and new tires put on. My 2007 vehicle has never felt better on the road. I would definitely go back for other services.

Expeditiously and prompt service. Competitive rates and excellent customer service. Highly recommend.

Friendly, very knowledgeable, quick and responsive
