Chad diagnosed the issue and discovered that Ford had removed the original switch and never replaced it. He even had us run down to a local junkyard to pick up a working switch, and then installed it for us at no charge so we could enjoy our vacation. Fast forward 15 years, and Chad has serviced all of our cars and trucks, as well as my daughter's vehicles. He's an excellent mechanic, incredibly honest, and someone you can truly trust. His wife handles scheduling, and she is just as friendly and helpful. I'm very glad we found Chad and AA Automotive.

Since it's a high-performance vehicle, buying new wasn't an option for me, so I went the pre-owned route. About five days after the purchase, the car suddenly downshifted on its own and the engine malfunction light appeared on the console. After restarting the vehicle a few times, the issue didn't repeat, but given that it had only been less than a week since purchase, I reached out to the broker. They referred me to Contra Costa Auto Service, a shop they partner with and one that had previously serviced this vehicle. Although the issue didn't resurface during their inspection, the technicians took the time to thoroughly review the situation. They explained that it could have been caused by moisture buildup leading to a temporary rough idle. What impressed me most was their professional knowledge, their transparency, and their recommendation to keep the extended warranty for added peace of mind. My son and I left feeling reassured and confident, knowing we had been given honest guidance. I truly appreciate their expertise and professionalism, and I would gladly return to Contra Costa Auto if any future issues arise with the car.

And they told me bring the vehicle in for inspection. I arrived about 15 minutes before they open and surprisingly the gentlemen instead of pushing me away by telling me we are still not open asked me to come in and I was able to leave my car that is above and beyond especially because I expected a please wait.We're not open yet. So they contacted me that day. Giving me a price range. And they kept their word. My vehicle was there over the weekend, the next day, I noticed a check engine light on. So I decided to drive back To Leale's they put it in the scanner. And they noticed that it had a code related to the cadillac converter one of the gentleman there told the one that was scanning for codes. Raise up the vehicle, make sure that all the sensors are connected. They could have missed not connecting one. And that can be the cause of the check engine light. They did remove that check engine light. And also they had the person that was working on my car. The day before, and he mentioned that one of the gaskets in the exhaust before the Cadillac converter was a little deteriorated, and they recommended that I change that. So I do appreciate the honesty. My car is Running even better than before, as they did not just fix the leak but actually serviced the transmission. I would definitely recommend this place. It is hard to find Honest mechanics And Quality service also customer service was great clean shop respect you guys.

What I appreciate most is that they never try to upsell unnecessary services or repairs. They take the time to explain what needs to be done and what can wait, which gives me complete confidence that they're looking out for my best interests, not just their bottom line. Fred and his team consistently go the extra mile to make sure my car is safe and reliable. Their integrity, expertise, and genuine care for their customers are what keep me coming back. If you're looking for a trustworthy mechanic, this is the place to go.

I'd been going to Diablo Auto Specialists the past couple years and had really good experiences…read morewhen 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.
