2015 Toyota Tacoma

If You Care About Your Vehicle, Your Family, and the Road Ahead--Go to Auto Diagnostics Repair & Services We drive to work. We take vacations. We travel to see family. We depend on our vehicles to get us safely through the things we need to do--and the things that make life worth living. That is why choosing the right people to work on your vehicle matters. Auto Diagnostics Repair & Services (ADRS) in Walnut Creek is that kind of place. I needed brakes for my 2015 Toyota Tacoma 4.0L V6--a truck I absolutely love. I had pushed the replacement about as long as I reasonably could, but when the time came, I wanted the job done correctly. I was also working within a budget. The Toyota service center had quoted me upward of $2,000 for the level of parts and service I wanted. ADRS gave me another option: best quality parts, excellent workmanship, a fair price, and people who actually took the time to explain what they recommended and why. Having served as a mechanic in the U.S. Army, I am extremely cautious about who works on my vehicles. I pay attention to workmanship, professionalism, safety, and whether someone takes genuine pride in doing a job correctly. I recognized that mindset at ADRS. Could you probably find someone somewhere who will install cheaper parts for less money? Of course. But that isn't what I was looking for. I wanted people I could trust with a vehicle that carries me, my family, and sometimes takes me hundreds of miles for work. ADRS starts with doing the job right. My situation also wasn't particularly convenient. I needed the truck completed the same day, toward the end of a busy week. My wife and I were preparing for an extended trip for our wedding anniversary, and I also had upcoming work travel between San Francisco and Los Angeles. They quoted me the job, told me they could get it done that day--and they did exactly what they said they would do. Then there is George - thank God for George. If you're a car person, ask for George. We immediately connected over our appreciation for automobiles and our shared Army backgrounds, but what impressed me most was his respect for people and his commitment to customer service. When I picked up my Tacoma, I even had the opportunity to see the incredible restoration work George had done on a classic Chevy Bel Air. If you love classic cars, ask him about it. Seeing that car told me something important: this isn't simply someone working at an automotive shop. George genuinely understands, respects, and loves automobiles. And George is backed by an entire team that demonstrated the same professionalism, ethics, and respect for their work. Another surprise was receiving a detailed vehicle inspection report that helps me understand what may need attention next. Rather than turning that inspection into another charge, they gave me information I can actually use to plan future maintenance around my schedule and budget. That matters. A great repair shop shouldn't just tell you what's wrong and hand you a bill. They should help you understand what your vehicle needs, why it needs it, what should be prioritized, and what can be planned for later. That was my experience with ADRS. My Tacoma went in needing brakes and came back to me the same day, with excellent parts, excellent service, and confidence that the work had been done correctly. There are dealerships. There are quick-service chains. There are mobile mechanics. And then there are those increasingly rare independent automotive businesses where someone actually takes the time to know the customer, understand the vehicle, explain the work, and build a relationship that makes you want to come back. I found that place in Walnut Creek, CA. If you live anywhere in the East Bay and you're looking for an automotive repair facility you can trust, give Auto Diagnostics Repair & Services an opportunity. Ask for George. Really Talk to Him. Meet the Team. Ask questions. Let them explain what your vehicle actually needs. Because at the end of the day, it isn't only about brakes, rotors, an engine, or a repair bill. It's about the vehicle carrying you and the people you love safely to wherever life takes you next. ADRS earned my trust, and that is not something I give an automotive repair shop easily. Five stars without hesitation. They are now my go-to shop.

While driving home, I noticed the front left tire rubbing against the fender liner, an issue that was not present before the service. I returned the next morning, May 14, 2026, at approximately 8:30 AM to explain the problem. The business owner became defensive and stated that he only removed the wheels and did not touch the fender liner. When I requested that the issue be addressed under warranty, he refused and said there would be an additional charge. I then agreed to pay to have the wheels returned to their original position, but he refused to work on my car and walked away. Throughout the interaction, the owner was disrespectful, condescending, and demonstrated poor customer service. I am escalating this matter to the California Bureau of Automotive Repair. ** Sam! I have no intention to scam you. I just wanted to have the issue addressed. I no longer have the interest in dealing with a person like you **

Big O Tires, Walnut Creek…read more 5/5 Stars A BREAKDOWN, A $900 ESTIMATE, AND A TEAM THAT RESTORED MORE THAN OUR CAR! You know what's worse than an unexpected car breakdown? AN UNEXPECTED CAR BREAKDOWN ON A SUNDAY! SIGH... Well, we now know exactly what it looks, sounds, and feels like when a starter decides to retire without giving two weeks' notice! And let me tell you, you'd be surprised how one little part can affect so many other things. We even had a charger that hadn't worked since we purchased the car, and wouldn't you know it, after the starter was replaced, that charger started working too! But let me tell you how we got there. Our car completely shut off, and despite multiple attempts, we couldn't get it jumped. Thankfully, some wonderful human beings stopped to help two damsels in distress. After exhausting our options, and with some guidance from the amazing folks at our neighborhood O'Reilly Auto Parts (they'll be getting their own review!), we learned that Big O Tires in Walnut Creek was open on Sundays. OPEN ON SUNDAYS! Already a point in their favor! We walked over and met Getty. WHAT A WONDERFUL HUMAN BEING! We explained everything that had happened, including the symptoms we'd experienced and what the people who stopped to help had suggested. Getty listened, was straightforward with us, and explained that it sounded like the starter might be the culprit. Then came the estimate. $900! INSERT SHOCKED FACE RIGHT HERE! Now, nobody wants to hear that number when their car has unexpectedly decided to stop participating in life. But what I appreciated was Getty's honesty. He didn't sugarcoat the potential cost or make promises he couldn't keep. He told us that if we could get the car towed to the shop, his team could take care of it that same day. So we did! The car arrived around 11 a.m. AND BY 2 P.M., WE WERE DRIVING AWAY! But wait, there's more! THE FINAL BILL WAS $100 LESS THAN THE ORIGINAL ESTIMATE! Not a hundred dollars MORE. A HUNDRED DOLLARS LESS! No price gouging. No unexpected charges. No attempts to sell us services we hadn't requested. Just honest communication, efficient repairs, and excellent customer service. AND CAN WE TALK ABOUT THE FACT THAT A WOMAN COMPLETED OUR REPAIR?! YES, MA'AM! I absolutely loved seeing a woman working in the shop and getting our car back on the road. She deserves recognition right alongside Getty and the rest of the team! HERE'S WHAT REALLY MATTERS TO ME. When your vehicle breaks down unexpectedly, especially on a Sunday, you're already stressed. You're trying to figure out what's wrong, how much it's going to cost, how you're going to get the vehicle to a shop, and whether someone can even fix it that day. The last thing you need is to feel taken advantage of. Getty and his team gave us the exact opposite experience. They treated us with honesty, compassion, professionalism, and respect. And THAT is how you earn customer loyalty. I've used Big O Tires in the past, but after this experience, the Walnut Creek location has officially earned its place as my first stop whenever we need automotive repairs. LET'S TALK ABOUT WHAT THEY GOT RIGHT! Customer Service: 5/5 Honesty and Transparency: 5/5 Compassion: 5/5 Repair Turnaround: 5/5 Value: 5/5 Sunday Availability: PRICELESS! OVERALL EXPERIENCE: 5/5 The combination of honest pricing, compassionate service, quick repairs, and Sunday availability is a recipe for creating a lifelong customer. So, if those are qualities you value when choosing where to take your vehicle, look no further than Big O Tires in Walnut Creek. AND TELL THEM WE SENT YA! Here's hoping you won't need automotive repairs anytime soon. But if you do, stop in and speak with Getty. HE'LL GET YA STRAIGHT! To Getty, the woman who completed our repair, and the entire team: THANK YOU FOR TURNING A STRESSFUL SUNDAY INTO A REMINDER THAT GOOD, HONEST PEOPLE STILL EXIST AND TAKE PRIDE IN THEIR WORK! You didn't just get our car running again. You earned our trust. And that is worth far more than a five-star review!

I have…read morealways taken my car to the dealership for all service, but recently I went to Big O to repair a nail puncture and I was very happy with the service. This time I talked with Cody who said that I actually needed the tire balanced. (I didn't really understand if I needed all tires balanced or fewer than all four, but I didn't really care because I knew I wanted them all balanced.) I came back a few days later to get the tires balanced. Cody helped me again. The lobby was very busy and he was the only person working but he did a good job helping everyone as quickly as possible. I chose to have all 4 tires balanced at a cost of $25 each. I left the car and it was ready within a few hours as promised. No additional costs or issues. My car now drives super smooth! Although I see that there are a lot of negative reviews, my experience has been very different. After two experiences with this Big O Tire store I'm very happy with the customer service and the work performed. I would definitely recommend them.
