Walnut Creek Auto Repair

My friend told me my left brake light was out. I called DAS and he said to come on down, even though it was near closing time. He replaced the light and I was back on the road, legally now, in less than 20 minutes! That is awesome customer service!

I previously gave a 4 star rating after discovering a problem when I picked up my Chev Tahoe. Jon had me bring it back, determined the issue and is in the process of correcting it at Diablo Auto’s expense. I will be bringing in my Jeep for Diablo Auto to work on it as well. I’m upgrading my previous 4 Star to a 5 Star now.

Jon is always accommodating . His excellent customer service is above board. His knowledge and kind attitude make it a pleasure to have our car serviced with him. We also want to acknowledge the technician, Jose, for his excellent service. He consistently does a good job working on the car. We can always tell when our car has been serviced. It drives so smoothly. We have been long time customers and will continue to do so. Thank you Jon and Jose for a job well done!

I've been taking my 2008 Honda Accord to Diablo Auto Specialists for years. Excellent, timely service. I have been very satisfied with their service on my car.

I had a good experience with Diablo Mechanic. Their service and price was reasonable. I recommend them and will bring my car to them again. Thanks

Great, fast and efficient.

I took in an Audi Q5 for a pre-purchase inspection. The folks I’ve eat Diablo were friendly and expedient in the inspection. Communication/inspection report from Diablo was thorough and sent in e-form. I recommend this spot.

Friendly, accommodating and thorough

John is an angel! I am so used to taking my Tesla in and having a part replaced instead of repaired I’d forgotten what it felt like. It was an easy fix for him, but it made my week!! He is my BFF now.

I can’t say enough good things about them! Even though my problem was impossible to detect, I very much appreciate the efforts made by Jon and staff to try and fix my car. They were relentless! Turns out it was electrical and could only be fixed by a reset at the dealer. Friendly, helpful, and caring. Thank you so much :)
