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

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

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.

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

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

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

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

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

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 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

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

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

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

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

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

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

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

Drove up from socal and noticed I had a panel hanging off the bottom of my car. I came by and they quickly put it back for me. Very kind and helpful! read more

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

They were kind and quick, knowledgeable and treated us honestly. We will be back with our other vehicles.

Very HONEST and trustworthy shop! I brought my Acura TLX here to fix a loose splash guard and they were able to fix it the same day! They even inspected my car and they had caught a transmission leak, that my local dealer didn't tell me about during routine maintenance! Now I will bring it back to my dealer and get it fixed through the warranty!! These guys were very friendly and accommodating!! I HIGHLY RECOMMEND this shop! read more

Auto Diagnostics Repair and Services - My car is new again - Auto Repair Near Me - Walnut Creek, California

We had a very good experience at this auto shop. The Mechanics are very experienced and the Company is fair in its pricing. I had to get an old car checked for safety and a minor problem and they performed in an excellent way. Completely satisfied. read more

I had a wonderful first experience here and I will be back! They did a comprehensive inspection of my car with photos and showed me what needed to be done immediately and what I was going to need to plan for.

My wife had a horrible experience at the Audi dealership getting her car serviced. So I looked up this place on yelp with high hopes . They did not disappoint. They checked everything I asked of them with no surprise charges or unnecessary repairs. They made our experience quick and easy! We will definitely be returning here for future maintenance and repairs ! Thank you Mr. Brandon and all the techs for your honest work and dedication. read more

Now that my dealership's car maintenance plan expired, I decided to try AutoDRAS for a check up and to address a few concerns. They were incredibly warm, patient, and professional. I appreciate how transparent they were with their process. Turns out, they were more affordable for my needs, even including the dealer maintenance plan I had. I've already added them into my contacts as my "go to" car maintenance company, that I can trust. read more

I took my 2022 Hyundai here for an oil change and received service that was honest, fair, and thorough. It's clear that the people here care about building customer relationships and educating their patrons - they aren't here to take your money or take advantage of what you may not understand about cars. The oil change and filter replacement took about 1.5 hours and i think it was worth the wait for such high quality service and care. Highly recommend!!! read more

Amazing service from start to end. Explained every item on the scheduled maintenance list and why they are in need of replacement, inspection, top up, etc. Does not try to upsell at all. Breaks down the estimate and the final bill as well, so you should never be caught off guard. Last of all, fast turnaround and right on their time estimate. Would definitely come back! read more

They did a great job with my battery replacement for a fair price. Appreciate it! Thanks!

Excellent customer service. I made an appointment, and they took care of my vehicle in a timely manner. The provided me with information regarding the inspection of my vehicle that needed my attention in the near future. I highly recommend them. Thank you! read more

Auto Diag is hands down the best mechanic auto shop I've ever been a customer of. Fahim, Azizi, Mohammed and Brandon are some of the most professional, courteous, and friendly guys out there. I've taken in three of my cars for service here, two of which had major oil leaks, and the guys here have been nothing short of incredible in their quality of work, attention to detail, explanations of the diagnosis, how they will fix the issue, and how to extend the longevity of the vehicle given the situation. They have been extremely fair about the pricing and have even found ways to help save me money given the rather labor intensive work they've needed to do for my cars. They are extremely honest and trustworthy, and will do everything in their power to get your car back on the road with the issues fully resolved in as reasonably short time as possible. You can rest assured that they will make the fix the right way, no matter the hours necessary to do it. I've had the front and top of two engines taken out for repairs, rear differential and transfer case gaskets replaced, and routine maintenance work done there, and for every repair, I have not had to go back to re-fix the same issue. On a personal note, I have never felt more like a VIP with any store than I have here. These guys are on a first-name basis with me, and I consider it a social visit every time I take my car in. These guys are my go to mechanics as long as they are in business here! read more

Great service. Explained everything. Car ready when saod it would be. Very professional. Highly recommend

I am very appreciative that they were able to perform a same day repair on my vintage BMW 740i - during the week I am extremely busy so their ability to perform the work on a weekend was much appreciated. Knowledgeable and reliable - I will be returning back. read more
