  My transmission started to go out and it was time for a rebuild. I searched around for shops and ADS seemed like an amazing shop from reviews and looking at their work and they did not disappoint not only did they do good honest quality work but they helped me through the process of seeing what parts I needed and what parts would work best for my situation. I have had many horrible experiences with other shops in the valley but I will fully entrust ADS with my veichle. When I went to pick up my vehicle it had a very minor hiccup I drove down the road a bit and a 02 sensor came loose I called them up and they said bring it back and we will get on it. As I pulled up ryan was outside waiting for me and he immediately got two of their guys working on it and had it all sorted in minutes and the owner even came out too apologize about the inconvenience. Again I am extremely impressed with this shop, their quality of work and how their employees present themselves and handle situations. Now my car is back to working order and is driving better then the day I got it. I will definitely be back and be recommending to anyone that needs automotive service thank you guys for the amazing experience!!!

  The service writer, Ryan provided a clear explanation f the work to be performed and the pricing of that service. He also suggested a few other items ta that will need attention in the near future but did not pressure me that they must be done immediately. Since the car is 17 years old it seemed to me to be a reasonable recommendation. I have used ADS for service on both of my cars since moving to Ahwatukee in 2013. While they may seem to be expensive I have checked around and that is not the case. Car repairs from a reliable shop such as ADS are not cheap. that is due to the complexity of the technology of today’s cars.

When the things they pointed out looked like nothing, I brought it to another Acura shop which told me that the $3500 of service beyond the timing belt service, oil and filters was completely unnecessary.

  Response from ADS – Automotive Diagnostic Specialties

  Thank you for trusting us with your vehicle. We performed a timing belt repair on your recent visit. We also quoted an estimate for additional services that were not performed. It sounds like another shop had a different opinion of suggested repairs than what we recommended. We only recommend repairs when truly needed and our outstanding reputation supports that. Our customers rely on us to keep their vehicles safe, reliable and roadworthy. We appreciate Robert’s business and are sorry that he wasn’t satisfied with our recommendations. Ryan, Manager-ADS

  Ryan and Mark helped me through a period of a month long root cause analysis with my Custom F100 frame off restoration. Their patience with me as I made many decisions as we guessed at best case scenarios. I have always felt since the first discussions that they were about helping me get down the road and about having a relationship not just a transaction. I only go to places where others have recommended and I only recommend service that I would trust for my family or friends. Their service and attitude is intentionally excellent as they live under a sign that says The Customer is #1. This puts us at ease as customers, and holds them accountable to what they aspire to deliver. Thanks ADS!

  My Daughter and Son in law were moving from San Diego to Ohio and broke down in Tempe. They were towed to ADS by the drivers recommendations. The water pump had blown it’s bearings and after tying into it ADS realized the bolts were seized at the block.To make it short, they held the U-haul trailer in their yard for free,talked them out of spending anymore money on the truck,and charged them labor only for services rendered. Sean and company impressed a worried Father, took care of my family and restored my faith in Humanity. If your looking for a trustworthy shop you’ve found the right place

Yesterday, we panicked when our engine light came on in our truck–especially since we are going on a short trip out of town. ADS was booked for the day, but Sean said come on down I’ll have a look. He plugged in an analytical gadget and shared the outcome. We were very appreciative of the time he took, late in the day . This is the kind of treatment that makes ADS stand out from their competitors.

  I would like to amend my first review. On my first review I gave a not so stellar review of the shop. While I still stick by what I mentioned within my first review (them doing good work but being expensive and putting a small dent in my car) I have sense had other dealings with them that has changed my opinion of them.

  During my past visits it appeared to me that they were not so generous in listening to the issues I have had with my vehicle and seemed as if they doubted my ability to perform my own vehicle maintenance. However, my mind has now been changed and I no longer feel that way. I also feel that they really do care about their customers.

  The back story — last week I had them do some carburetor repairs on my vehicle to get it to pass emissions (it passed). Just a few days later my vehicle stalled out and was not running properly. I thought it was a blown seal in the carburetor and I had the vehicle towed back to their lot over the weekend. Upon explaining the problem, they apologized for the inconvenience, and told me they would take a look at it and let me know what was going on. As it turns out it was a completely separate issue – I had a plug up catalytic converter.

  They were also very understanding as to my financial situation, having been laid off from my employer a few weeks prior, and as such they didn’t charge me for the new diagnostic service. I also feel that they were genuinely concern for me and my situation.

  Thanks guys it really means a lot.

  While they do seem to do good work, I would not recommend them. They are overpriced! Additionally, if you work on your on vehicle, like I do, they seem to come off with an attitude as if you don’t know what you are talking about.

  I took my 79 Trans Am in because it was not passing emissions the bill was $470 for diagnostic, timing and some carburetor work. Another shop probably would have charged $300 to do the same work.

  My contention with them is on three points.
  1) They charged $90 to “test” an EGR valve which I told them was new (I replaced it myself a few months prior). Come guys $90 to remove two bolts, check for carbon and ensure it holds vacuum – really?!
  2) They also had my car for a full week before working on it which was an inconvenience.
  3) When I got it back there was a dent in my driver side door and it is obvious that their tech must have hit the post on their lift with it. I chose not to mention to them because I discovered it the next day and the car is a restoration project. But it does show a lack of respect and care for a customer’s vehicle – especially since they chose not to mention it to me – as if I would not notice! I am guessing it will cost me about $200 extra to have a body shop work out the dent on what would have otherwise been a straight door when I have body and paint done on it. If my car would have been pristine you bet I would have raised a stink about it – I guess I am just too nice.

  We went hear a couple of years and initially thought they were good, but then they started to push unneeded very expensive repairs with irrational reasons why it was needed.

  Initially we went in with specific requests (oil change, new battery, the new battery was bad to please get it replaced, etc.). Things seemed ok.

  They said they didn’t do regular maintenance on cars with miles over 100,000, but do regular oil changes and they check it over each time we come in. Soon they started to say we needed a very expensive repair that made no sense.
  They said an engine mount was cracked and they all needed to be replaced. Of course this was concerning.
  Despite the fact that each time someone waited for the car and they were asked to show us any needed work while the car was on the rack and them saying of course, each time they came to talk about repairs the car was off the rack and could not be put back on the rack but we could come back and they would put the car back on the rack to show us.
  We finally did that, the “cracked engine mount” was a very small crack in an otherwise good condition gasket, not in the engine mount.
  The song and dance story started at that point. Of how they considered the gasket part of the metal engine mount, of how the engine could fall down out of the car, etc. etc. When we pushed back they said well that crack might have been that way for a long time and could be fine for a long time. We asked can’t we just monitor the crack, they agreed that was a good choice.

  But next visit, again all the engine mounts had to be replaced right away, and again the car was no longer on the rack to be looked at. When we asked them monitoring the crack, they said we have no information of what the crack was like last time you came in (e.g. they put down no information that would enable them to monitor it).

  Again the song and dance was going on with irrational reasons of why we needed to do the work. We monitored the crack, it didn’t change (still has not years later), and didn’t get the work done. So they started to come up with other expensive repairs that needed to be done.

  We finally got tired of this and checked out several other shops. We paid at each one for a through look over the car. None of them suggested the repairs this place did. We choose one that not only shows us the car on the rack, but found a repair that ADS missed that was actually needed, and gives nice logical verifiable suggestions with pros and cons when they bring up a repair. Best of all, they encourage spending a very small amount of money on diagnostics (including monitoring things or checking out obvious things first) before spending a lot of money on repairs that might not be needed at all.

  Response from ADS – Automotive Diagnostic Specialties

  ADS – Automotive Diagnostic Specialties has an impeccable reputation with our customers, represented by our A+ rating with the Better Business Bureau. The last time we had the opportunity to work on Scott’s vehicle was on 11/18/13, and the odometer reading was 242,810 miles. ADS services a very wide variety of vehicles with over 100,000 miles on them. In fact, we have had success with keeping several vehicles on the road with over 200,000 miles due to quality inspections and repairs. From Scott’s initial visit on 5/19/11 to the final visit on 11/18/13, three separate ASE-certified technicians individually inspected Scott’s 2001 Honda and collectively agreed that the engine mounts were in poor condition, in need of replacement, and were worn beyond their useful life. We had made several recommendations for services needed, and the majority of services recommended were declined. We only recommend repairs when truly needed and our outstanding reputation supports that. Our customers rely on thorough inspections to keep their vehicles safe, reliable and roadworthy. We are sorry Scott wasn’t satisfied with our inspection process, and we wish him well. –Greg LaFontsee, Owner

Due to the note we left, they pushed our vehicle into the bay to make sure no damaged was done to the engine. They called me right away to tell me that a hose system under the van for the oil need replacing but no further damaged was done. Helpful, smart, and careful! What more can you ask for? Please note this is not our first contact with ADS. They also service an antique vehicle and a hybrid for us. In other words if you drive it, they can fix it.

  went in for an oil change. work performed promptly,but I was charged 10.00 additional dollars for a tire rotation. This is normally included with my regular shop. ADS inspected the car and provided written recommendations and repair cost quote.

  Response from ADS – Automotive Diagnostic Specialties

  The staff at ADS is troubled any time one of our customers is unhappy. We have a following of devoted customers and an A+ rating with the Better Business Bureau. We know that our customers have worked hard for their money, and we repair vehicles with that in mind. We are dedicated to making sure every customer’s vehicle is repaired correctly the first time—every time. Lane, it is our policy to include do a tire rotation with each oil change, and you should have been told that. We apologize that you were not. We would like to offer you a $10 credit toward your next service to apologize for the confusion. In addition, because you are now an ADS customer, you will be receiving coupons for future service that include free tire rotations and $25 off of lube, oil and filter service. –Greg LaFontsee, Owner

  Being a woman going into an auto repair shop can be frightening. I broke down on the highway and my car was towed to ADS Automotive diagnostic specialties after hours. Dale from ADS was there waiting for me. I explained the problem and he informed me ADS would take care of my car on the next business day. I had to call for a ride home and he even waited in the parking lot with me until my ride arrived. I was called the next business day informing me of a very minor problem that caused the vehicle to break down. This is a company without reservation I highly recommend for their honesty and great service. I will now only trust my car to ADS.

  No one enjoys paying money for auto repairs, but I can say that when I paid for my first visit to ADS I walked away feeling like I just paid for something worth the money. I brought my vehicle in for a failed break booster on a 2002 xterra. I was expecting that after the initial diagnosis I would get a call from the sales guy to tell me about all the many things the mechanic noticed was wrong with my 12 year old vehicle. This was my experience on my past few visits to various auto shops around Chandler. When I did get the call after diagnosis I was surprised to hear of only a few things my vehicle needed and the sales professional actually negated many of the things I was told were wrong with my car by the other shops. We ended up fixing a major safety issue as well as the break booster I originally went in for. I never felt any pressure from typical sales tactics and walked away feeling like the necessary work was done and with quality. Very good experience and would definitely recommend.

  WE have used ADS for several years and send our friends & family to them for honest, reliable, excellent service. ADS consistently maintains the highest standards of auto care & maintenance, they will tell you honestly what your car needs and will even tell you if they feel it is not worth the high costs of repairs (on an older vehicle which is more than it’s resale value). It is so rare and hard to find an business run with integrity and honesty and ADS is that rare auto repair facility. I highly recommend them with complete confidence, based upon several years of working with them.

  Customer Service was great! I just had my thermostat repaired at different shop and shortly after the check engine light came on. After the diagnostic at ADS, Mark and Sean were very informative and explained that the engine was now not getting up to the recommended operating level. (Coolant was continually flowing through the radiator.) They did the repair and installed a new thermostat and informed me that the one previously installed was not the correct model for my jeep. The one previously install would only reach 160 before opening and my vehicle level needed to reach 190-195 for proper performance. They also showed me the thermostat they replaced which also did not have the correct rubber seal. All around great service and very informative, Thank you.

Greg (the owner) was kind enough to check on me several times while I was waiting and you can tell that he is passionate about running a top notch business. I would HIGHLY recommend ADS for any automotive repair and will continue to send my business their way.

  Thanks for a great job ADS!!!

  This is the 3rd time I’ve used ADS – I highly recommend them to anyone looking for honest, quality work. In this day and age, it is hard to find competent carburetor mechanics – ADS TOPS THE CHARTS!!

  They were fast in getting me my car back, and very efficient with the work that was preformed. I had went to them after a bad auto place before, and i was more satisfied with them in the end.

Now I get the HP out of my Challenger that one would expect from a 6.1 Hemi! I will definately go back for any future mods!

  I am a long-time customer of ADS (since 1998) and have had lots of work done there over the years, regular maintenance and various repairs on 7 different vehicles of all types and ages. ADS has nearly always done the job right and on time . . when they don’t, they still make sure that I’m satisfied. The owner (Greg) and his entire staff are very knowledgeable and professional. Most recently, John Thompson (Service Manager) personally checked the vital fluids in a truck that I seldom drive and was having a heater core replace in. John found my oil level to be dangerously low, added the necessary oil to fill it and then let me know about it. I could have very easily blown up the engine if it had not been for his caring and effective customer service. Of course, I will continue to highly recommend ADS to anyone needing auto service from a trustworthy, capable organization.

I would say that the initial price $96 just to find out what the problem was is a little steep and almost turned me towards finding other alternatives. Other than that, the service was great.

I previously brought the vehicle in for a battery problem that should have been fixed by the Honda dealership. Dave and Bob are tremendously helpful. In this case, Bob not only had the battery replaced quickly, but also went the extra mile to contact Honda to reset the codes for the radio, etc. I originally came to ADS based on a friend’s recommendation and would do the same for another friend.

  I was referred to ADS by a friend who had previous work done. Me not knowing anything about exhaust systems and needing Exhaust Class 101 met with John. John spent a lot of time educating me on what I was getting and what was available for my Mustang. I learned of other options that were available to me for improving the HP and overall performance of my mustang. The shop is outstandingly clean. My exhaust system was ordered on a Wednesday. I was told the system would be in on Friday and he would call. On Friday, I received a call “as promised” and work was complete within 3 hours of that call to me. When dropping & picking up my car I was given a courtesy ride to and from work. I had the opportunity to speak to other staff members at ADS and all were professional & outstanding. Definitely will have them do further work to my Mustang. ADS is one I can Trust !! Thank you !

  The people were courteous, knowledgeable and friendly and the total out the door was exactly what they quoted me. My car needed a new radiator, it had cracked on the top and was leaking fluid which gives off a burning maple syrup smell. When I got the car home Friday night and pulled in the garage, there it was again, that powerful burning smell, I thought for sure a hose disconnected or something went wrong, turns out they never cleaned off the area when they were done with the job, all the old burnt residue was still under the hood. I now need to take my car to get the engine cleaned.
