I’ve been a customer here for a few years and have never been disappointed with their service. I have multiple vehicles in their database which had been brought to this establishment for repair over the years. Whether it was preventive maintenance or time for new brakes this is the place I chose with no regrets. I am a repeat customer that will always recommend anyone to chose Diaz Auto Service for your maintenance needs.

We came in today desperately needing our battery replaced as we needed to head out of town and no one was available or could take us in due to us having a foreign vehicle. Not only did the team identify the battery we brought in that we just purchased from AutoZone was incorrect, they sold us a battery that worked and stayed after hours just to help us. I can’t thank them enough for being so efficient and helping us in a minutes notice. Highly recommend

Reply to owner: Obviously I'm not a returning customer to this shop, so I wouldn't be in your records. I'd expect the owner to have some common sense, seems like everyone who works here is mediocre. Do better Waste of time trying to set up a diagnosis on my car, don't bother calling either the girl answering phone calls doesn't know the answers to questions and doesn't offer any assistance. Horrible customer experience

I recently brought my 2008 Lexus ES 350 to this shop with one simple request: to have my brakes serviced. Unfortunately, the experience was incredibly disappointing from start to finish. First, the customer service was unprofessional and unwelcoming. I didn’t feel respected or valued as a paying customer. Communication was poor — I had to constantly follow up for updates, and when I did get a response, it was vague and dismissive. Worse than the poor service was the quality of the work itself. Despite assurances that the brake service was completed, the issues persisted immediately after I left the shop. It quickly became clear that the job was either done incorrectly or not done at all. I paid for work that did not resolve the problem and left feeling taken advantage of. I strongly do
