Great service, prices and clean locale. The repairs done today were on warranty so there was no charge. Highly recommend this establishment. There is a room with TV to wait in while repairs are done. Restaurants within walking distance in case you have to wait a while.

Took my truck to get Ac checked out, told them I felt like there was some serious issues with the system. They said they would check it out, shortly after they called me and told me there were no leaks and a couple of fuses were burnt out. They recharged it and said it was good to go. Took it home and it felt kind of cold but not where it should be. Next day it stopped working completely. Called him back and told him what happened, he said that they checked everything, I told him that whatever they did, it not work and that it was a waste of $200.00. He said that it was not a waste because I picked it up working. I said, yeah, for one day! He then told me he would probably have to put in a new compressor which would be $700.00 or more, I told him you should have known that from the beginning! I took it to another Mechanic who said it should have never been recharged because the compressor was leaking oil and was really in bad shape. He fixed it and it is working great! Moral of the story, if you have too many cars and not enough mechanics to fix them, be honest and say so, don’t give people their vehicles back not fixed right!

Took my car in for a fan assembly replacement. Cosme told me he would get his discount from the supplier and only charge me what he paid for the part. Dropped off the car in the afternoon and he was done with it the next morning. Very quick and very reasonable.

Looking for an honest, trusting mechanic as most of you know, isnt easy to find. I cant tell you how pleased I was to have found Cosme. I took my car to him once before and didnt charge me. If he cant troubleshoot your car he will tell you not BS his way to get your business.I had already arranged to have Cosme fix my parking brake which was stuck in downward position. Also, asked him to replace spark plugs. I left to take care of an issue and when I returned his son, Victor, started asking me questions that I had already answered with Cosme. I get frustrated because I felt like he needed to be in control, he was asking legitimate questions. Where I have issue is that he was persistent and wouldnt;t just accept I had spoken to his father, Cosme. I requested several times for Victor to please give me space. My frustration is that I finally found someone that I trusted.I approached Cosme with dilemma and gave him my car key. His son approached us and I put out my hand to apologize. He rejected my hand and actually became rude and aggressive saying he could refuse work to anyone, Finally, after several exchanges I asked him to please leave me alone. He wouldnt, continuing to badger me with how rude I waswith him. I looked Cosme to help diffuse situation .and he surprised me by saying, we dont need your business.I get it, he has that discretion and it is his son that I was having issue with. However, Im the customer yet I was being berated by Victor. I asked hie several times, to.please leave me alone, He didnt, finally in frustration and feeling very disrespected I look to Cosme to diffuse situation. If I hadnt had interaction with Victor my car would be getting repaired.This review is written because I felt I have no other recourse. As some of you said, hes (Cosme) honest, trustworthy and very knowledgeable, if you need your car repaired here, I would highly recommend this shop. The only reason I give it one star is because of my interaction with Victor.Again, if youve found Cosme and this shop by all means youve found an excellent repair shop

Okay if you read my review and you have read a few of my reviews you can see that I absolutely love to give credit wheres its due.If your like me I find it hard to find an honest to goodness,straight forward, kind,knowledgeable mechanic. Well I found one! Advanced Auto diagnostics was on point. No nonsense took care of my brakes guaranteed their work for 6 months and replaced my broken side view mirror. Cosme and Victor my tech were amazing! I am going back to get my air fixed and Im confident to walk in with the amount Cosme quoted me on because YES PEOPLE!! THEY ACTUALLY GAVE ME A QUOTE ABOUT THE JOB ON MY BREAKS AND NO HIDDEN FEES!! AMAZING!!♡ (ESTABLISHED TRUST & PEACE OF MIND)So if your looking for a licensed group of mechanics & trustworthy. Visit this place.

Took my truck in to get the A/C fixed. They did a great job and its blowing cold air again! 😀 Very professional and good price! Thanks guys!

Great service. Tells you what is wrong with your car and what needs to be fixed 1st. Prices are fair for the great job they do. Doesnt try to upsell and are not pushy.

Only place I take my vehicles to. Openly honest and I feel comfortable that I will not be taken advantage of at any time.

Cosme is very informative, helpful and his work is excellent. I will recommend anyone to bring your vehicle here.

I have been to Advanced Auto Diagnostics on three different occasions and am always impress with their professionalism and customer service. The place is immaculate and Cosme the owner is very friendly and always make you feel special. It is such a good feeling to go there and know they are honest with their diagnosis and are ready to put you back on the road. I highly recommend this place to have your auto professionally taken care of.

They are always nice, helpful and take the time to answer any of my questions. Great people!

I can’t thank them enough for changing my battery terminals. He was very nice and professional, price was excellent. I will definitely be going with them for future needs with my car.

Cosme did a great job explaining what was going on with the air conditioning in my vehicle.

Great place to get work done to your vehicle. wont play around with whats wrong.

Very good experience here. Lucky to find this place. From out of town visiting and ran into mechanical issues. Was allowed to see them check what was going on and gave me a straight forward diagnoses. Fair pricing and honest work. Overall would recommend

I have been going with Cosme for years now. He doesnt promise you the world and he delivers on time. He doesnt mess around by guessing whats wrong with your vehicle, he actually knows. He is quick, clean and efficient. His prices are reasonable for the work he does and its always done right the first time. He checks your vehicle as soon as you get there and doesnt waste time. He is the most honest mechanic in Texas, he will let you know exactly whats wrong with your vehicle.

I took my truck to a dealer for the AC. The dealer was going to charge me over $ 500 to fix it. Cosme did a pressure check ( which the dealer hadnt done ) and charged me about $ 70. Problem solved

Super clean shop, honest and fair, great mechanics.

Cant give these guys enough stars. My daughters car had been overheating. Brought it here and within two hours of dropping it off, they had diagnosed the issue.Car was ready the next day for about half what the dealership would have charged.

Fair price for excellent work!

Excellent service and excellent job !!!!
