I am shocked that nobody has written a review for this place yet! I was beginning to give up hope to ever get a honest , polite and timely auto service in Antioch. Brian will not do any repairs unnecessarily, will remind you of the work that needs done, and treat you with respect. The brake squeak in my old CRV, the one which nobody before him could fix, is now gone! The car is running smoothly(and it has 130,000 thou. on it! He has no lack of business, so call ahead of time to bring your car in.

Always excellent service and they offer the best advice for my car! Loyal to them for two years now and counting! They're also very good at letting you know right away about the latest news on your car. Impressed with how organized they are!

Brian and his crew of auto technicians have taken great care of things I cannot do myself (as a former mechanic) and has always been fair with us. One time they worked about 3 hours trying to figure out a problem, and when they figured it out, they only billed me for the initial diagnostic fee. I authorized the repairs and he counted the diagnostic fee towards the repair. I've referred several people to them as well and each person has called me later to thank me for sending me over there. I would send my closest friends to them, and I have.

My experience at Auto Diagnostic has always been excellent. They are honest regarding the repairs I need. They never tell you what needs to be fixed, unless it really does need attention. I have gone to Auto Diagnostic for more than 10 years. I would never go anywhere else, including a new car dealership. The people who serve you are polite and informative. The owner, Brian sets the high standard for all the people at the shop. I HIGHLY RECOMMEND THIS AUTOMOTIVE REPAIR BUSINESS!

Auto Diagnostics and Repair has been caring for my cars for 9 years and I wouldn't go anywhere else. I trust them and they have proven many times that I can. That's very important to me and I wouldn't think of going to any other repair shop. Everything they do is top notch and professional.

I've been going to other service areas in Antioch for years and I am so glad I discovered Auto Diagnostic and Repair. I have read the other negative reviews here on Yelp and wonder if they really went here. The customer service is of the highest order. They take the time to explain what is going on with your car (by the tech that will work on your vehicle). Being an IT guy, I am impressed by their systems to keep track of your vehicle status and the itemization of work that they recommend for you. If you live in the area and need quality automotive services this is the place. My Expedition is running better than ever at 140K, they fixed my AC (something 360 never did well for me). In the past I always felt that I got taken advantage of when I needed repairs... Auto Diagnostic and Repair is a class operation. They also sent me a "club" card booklet with discounts and a place for me to put my receipts for service.

I have been going to Auto Diagnostics for close to five (5) years. I have a 1991 Ford F-150 Custom pick-up and I can proudly say that I am the original owner. Brian and his crew have done the upkeep on my truck and each time they say, " this truck runs pretty good." This has the original engine but his crew have performed the maintenance that surrounds it. Brian may not personally work on every car but he always gives it his blessing before it is turned back over to the owner. Yes, I have spent some money over the years, but you know what? It was worth it. I got it painted to it's original color,, some new interior re-done.and i am always getting compliments. It has 198,000 miles and I take it one day at a time with enjoyment. NO TRUCK PAYMENTS. Thank you Brain,Christina and the whole crew. You guys really took care of me. All the best.

I only have good things to say about Auto Diagnostic. I have had my Dodge RV in there for diagnostics, repairs, both minor and major, plus general maintenance. The staff are friendly and efficient. The work has been first class, priced as quoted and on time. They will happily give you a ride home and pick you up if the vehicle needs to be there for an extended time. I would confidently recommend them to anyone looking for a reliable and customer friendly repair facility.

Everything is thoroughly explained and old parts validate the need for work. The work is guaranteed and there is follow up. I have been to many shops and dealerships and I am so thankful I found Auto Diagnostic. I had surgery one year and received flowers from my friends at Auto Diagnostic. Christine and Brian's advice is so helpful. They go above and beyond the call of duty so many times. Thank you!

This place is awesome! Three ladies work at the front desk and that makes it very personal. They take care of my needs in a timely manner and they always offer a ride to and from the shop. They give a rose when they are done! who does that?? what a great way to end the job! They offer free oil change if I refer a friend. Brian, the owner is very involved in the community and I appreciate that. I have never seen an auto repair shop care about the community. I recommend you give him a chance to show you what an honest and professional environment has has created. They follow up with a thank you note in the mail and a phone call to ensure my satisfaction. I also love receiving a newsletter from them in the mail. They just have lots of little things that keeps me as a happy customer.

I know when I take my vehicle in for service or repair I am treated with respect and the staff lessons to everything I say that is going on to fix my car the first time. Awesome staff and a dependable and reliable shop.

I think the words that best describe this shop are thorough and professional. No games. You get quality repairs with a full explanation and assurance that when you leave, the car is working perfectly and you have no worries. I love that feeling of confidence. Brian the owner is great! His passion is cars and you can feel it immediately. Add to that really nice people who will bend over backwards to make you happy. My wife and I are so happy to have found them!

My husband always took his truck to the Chevy dealer, when I made an appointment with Auto Diagnostic he was not happy with me. After he got his truck back and it was running the best it had in years, he is now a faithful Auto Diagnostic customer like me.

I love this place. Chris is very nice. It's very hard to find a good mechanic and one you can trust. I'm so glad I found this place because they are great and I trust them so much with my car and my husband's car. They do great work. They also work fast. The work environment seems to be extremely fun.

The owner, Brian, was very informative and professional, with a smile! I am very happy that my Check Engine issue was fixed, and that I found a great and honest shop in Auto Diagnostic & Repair! I would recommend this shop to everyone, Including Family! ;) And when I went back for the follow up, Kris at the front desk, took care of it, and was professional, friendly and made me feel like a valued customer. I would give Auto Diagnostic 6 Stars if I could ;)

Great place to get your car worked on

This is THE best place to have your automobile repaired and serviced, everyone who works here is beyond professional. This place has the latest state of the art diagnostic equipment not to mention the most up to date training available. You will not find a better staff to serve you. This is a family business with family morals. They stand behind every repair no matter what, this is what good business is. I feel like family when I bring my autos here.

Best place to go for great work

Brian and his team are great at keeping my cars running smoothly! They are always pleasant to work with even though its not always fun to need mechanic work done on your cars. I love that they make recommendations but give you the information needed to decide what needs to be done now or can wait til later. I highly recommend Auto Diagnostic & Repair.
