I have a 2019 Lexus ES300, and when I took it to the dealership, they gave me a huge list of recommended services with a very expensive estimate. I was honestly stressed out and wasn't sure what to do. A friend told me about this shop, so I decided to get a second opinion. That was the best decision I could have made. The staff took their time to go through everything with me and explained each service in a way that actually made sense. They were honest, professional, and never tried to sell me anything I didn't need. They completed the repairs using OEM-quality parts and charged much less than the dealership. The difference in price was unbelievable, and the quality of work was excellent. My Lexus is running great, and I feel much more confident knowing the work was done right. It's rare to find a shop that is both knowledgeable and trustworthy. If you're looking for honest service, fair pricing, and people who genuinely care about their customers, I highly recommend this place. read more

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. read more

Auto Diagnostics Repair and Services - 2015 Toyota Tacoma - Auto Repair Near Me - Walnut Creek, California

See all

My car's check engine light came on and randomly started high reving so I got off of the freeway and searched the nearest auto repair shop. They happened to be the closest. It was later in the day so I assumed I wouldn't get service. But they immediately took me in and were able to have me out in one hour. They are super fair priced, it's $175 initial plus parts. However, They said if they find anything significant, they wouldn't charge me. They were super professional, informing me that they would not move forward with any work, unless approved by me. The office was very clean. And the mechanics were working super fast and efficient. They gave fair pricing for honest work quality work. Overall, this is my new trusted mechanic, I highly recommend them to anyone! - AD read more

I know nothing about cars and they made me feel very comfortable there. Then, they backed it up with work that stopped my oil leak, made my window work and my breaks do the job without breaking my wallet. I found my mechanic! read more

love this shop!! this is definitely my new go-to for auto repairs. my accord needed a new cat converter, and with all of CA's ridiculous CARB regulations, the more quotes that i collected, the more stressed i became. enter auto diagnostic: jorge replied to my request via yelp very quickly and asked me to stop by so that he could get my engine family number in order to give me an accurate quote. he was able to come in lower than any other shop to this point, and he even got me in the next morning. to top it off, he ordered me a lyft to my work and thoroughly checked the details of the driver to make sure i was getting in the correct ride. i appreciated his expertise in parts, and also the way that he treated me. i believe azizi is one of the mechanics? he and the team fixed my car efficiently and quickly, and i'm super grateful for my experience with them all. read more

The best shop in Walnut Creek--highly recommended for great prices, excellent service, and a professional experience.

Responded fast. Gave a very detailed description of the problem and the fix. Very easy drop off and pick up. Great communication. I'll bookmark this place to go back again. read more

Excellent and honest help by Vince. I would recommend him and the shop for diagnostics and repairs.

As a female, let me tell you how rare this is: I found a mechanic shop I actually look forward to visiting. That's like finding a unicorn that also does oil changes. I brought in a car for a pre-purchase inspection, and the whole team treated me like I was their only customer and I've noticed they treat all their customers the same. They walked me through everything they found in plain English, no scare tactics, no mystery charges, no "well, while we're in there..." upsells. Just honest answers and straight talk. I've met everyone that works there and they're all wonderful. Here's the part that says it all: this shop is a good drive from me, and I've already gone back there for a manufacturer recommended service. Voluntarily and with a smile. I passed probably a dozen other shops on the way, and I didn't even glance at them, not even the one that's literally 3 minutes from my home. To be honest, if I were to move, I would drive up to 2 hours away to see them. When you find people you trust with your car, you don't let a little geography get in the way. I've had many scum bag mechanics try to take me for a fool in the past, NOT this garage though. Love them. Definitely value for money. I wish I could give them 100 stars. Can I leave a tip in the form of a review? Because here it is. read more

This business answered quickly with cost at their location for an oil change and basic service, including tire rotation.

I had an excellent experience with the auto diagnostics repair and service. The team was professional, honest and fast. They diagnostic the issue right away and fix it with really good and unexpected pricing. I highly recommend this place. read more

I show up for my 830 appointment and am told the owner took the mechanic to go look at some cars and wont be back til noon. I come back at noon and now they wont be back til 1. Super unprofessional and untrustworthy. read more

I request a quote for service on the week. Within an hour I recieved a response and before the day was over...a reasonable quote. We agreed parts were ordered and early Monday morning an appointment with commitment the service would take 1 hour. 56 min later the job was done and done right. No sales pitch no up sell. read more

They were so helpful and kind! As a female Im always nervous to go to a mechanic for the first time when moving to a new area but Azizi and his crew were so gracious, honest and kind. And also very fairly priced compared to others that quoted me. Will definitely be coming back! Thanks again! read more

They were fantastic! They completed my oil change, performed a full vehicle inspection, and topped off all the fluids that were running a little low. The entire process took only about 35 minutes. They also provided me with a printed copy of the inspection report and took the time to explain everything in detail. I highly recommend them, especially if you're not very knowledgeable about cars, like me. Their professionalism and clear communication made the whole experience stress-free. read more

I took delivery of a 2021 VW Tiguan R-Line w/ 63,000 miles from Carvana & wanted to get the "pre-delivery" inspection done before the 7 day period from Carvana. They did a full inspection of the car & listed everything that needed attention & a list of what's to come down the line. I ended up needing a new battery, which the current one was nearing end of life. I had the work done considering all the electronics in the car. I've owned german cars for the most part the past 10 years & I'm super particular w/ the shops my vehicles go through, these guys know their stuff & the value is worth it! Big thanks to Mike & Azizi for the honesty w/ the whole inspection & laying out what mileage to consider doing other major service items on the vehicle. The plus side, they are open on Saturdays! Will be returning for all my service needs on my German cars! read more

My car needed struts and brake pads, and Mercedes-Benz quoted me a crazy price. I found this shop and they did the job for almost half the cost. Very honest and professional people. The car drives great now. Definitely recommend this shop. read more

Auto Diagnostics Repair and Services - Auto Repair Near Me - Walnut Creek, California

Outstanding repair shop worth the drive even if you don't live nearby. Small enough that your not just a number but large enough that they have all the experience and tools and knowledge to do things right. I'm not all that impressed with new cars these days. Direct injection, turbo and CVT transmissions - I've had already two of these new modern cars and I've been looking back to older cars and appreciating them more and more. If you do have an older car the thing you do need is a trusted mechanic to make sure things are going ok. There are designated mechanics for both German and Asian cars - and each mechanic knows both very well. I like both types - I personally think a 4 cylinder Honda makes sense as a grocery getter and a larger German car is perfect for long road trips. Vince recently looked over my Mercedes before a lone road trip to Seattle and it is mostly up to date with a few things left for the future as they weren't urgent. Michael is great at informing everything that goes on and what the mechanic sees and tells you about things to keep an eye on for the future. I remember every individual piece of work they break down just in case you don't want to do everything and are on a budget. If you have a CDI, TDI, bluetec, x5d, 335d, 328d or similar Vince is the guy you want to see. read more

I found this shop because I was looking for someone who would take parts I bought and put it in my old car. the car fell apart but that was kind of inevitable but the service I received was phenomenal. I've been to this shop for my new car ever since and they have always treated me so kindly and explain things carefully to me. they gave me a root beer float one time because I had been waiting so long and I guess they felt bad but I don't mind waiting for excellent service. the prices are very fair and you can tell they won't cheat you for extra money. I have found the shop that I will be going to for everything my car needs from now on :] read more

Super great service. I take all of my cars here and get the best prices around. The people are great and honest.

They did a great job! Shout out to the owner Fahim and the mechanic Azzizi who did excellent work on my car and were very reasonably priced! Will definitely return if I ever need service again!!! read more

I basically got scammed here lol. They had to replace my all of my 3 belts for my 4Runner cost me around 3k, just for the AC belt to snap in less than 6 months. They said, I would get a refund, but I never did. They saw a young female adult and took advantage (I'm from SoCal and my car broke down in NorCal) so do what you will with this information. read more

Purchased a used 2020 Mini Cooper S from CarMax. I was suspicious of the very, very low mileage, so I brought it to Auto DRAS for a Post-Purchase Inspection to make sure nothing was amiss. It got a clean bill of health! Brandon and the mechanics on duty tag-teamed to get me in and out very quickly. There is a very nice coffee and tea shop two doors down if you need to wait or work in comfort during repairs (or while you're waiting for your Lyft). Big thanks to everyone at Auto DRAS for giving us peace of mind on the fly and at a very fair price. I'll be back. read more

Had a loose battery and they fixed it within 5 minutes! Will definitely be coming back for whatever else I need. Highly recommended.

The search for a trustworthy mechanic is over, once you visit this shop. I needed service on a Sunday and at 8am, Auzeze answered the phone with great kindness and availability to help. This team was amazing to work with and the prices and turnaround were great! They even offered to drop my car at my home for me, how awesome! I've told several people about them over the last couple days and a friend is heading in next week. Full service, including oil. Best place and only place I will go from now on! Thanks guys! read more
