These guys are amazing! In approximately Sept 2020, I dealt specifically with shop manager, Ryan Graham, who took great care of me. I live in Tucson and had taken my Honda Accord to a Honda dealership in Tucson, due to oil leaking from the engine, onto one of the spark plugs. The leak persisted and so the Honda dealer told me that the only solution was to do a re-ring job (about $4,000.00) or install a new engine - all of which is terrible news, given that the cost for an engine ranges between about $5000.00 and $10,000.00 depending on a new or used engine. As I was desperate for a second opinion, I contacted Bumper to Bumper Radio Mgr. Mike Henry, who recommended ADS in Chandler. Living in Tucson, I'd never been to ADS and I found it hard to believe there could be any repair shop better than the factory dealer, where I bought my car. However, Mike explained to me that the guys at ADS were not only the best in Arizona, but possibly the best in the nation, for accurately diagnosing and repairing automotive problems. Upon speaking with ADS Mgr. Ryan Graham, he explained to me that there was an alternative to replacing my engine or re-ringing it. Ryan explained that they've performed oil treatment services on engines that are leaking oil and in many cases, the engine treatment seals the rings, from where the oil leaks. The service, including the oil change costed about $350.00 - and it amazingly fixed the problem! ADS saved me thousands of dollars and it only took them a few hours to do the job! This is truly amazing and I am now a loyal ADS customer! So if you're looking for the smartest automotive technicians who are honest and give outstanding customer service, go to ADS -- even if you live out of town, it's worth the trip! Jeff.
Description of Work: Performance oil treatment was done.

They also give me my AAA discount. They're great. They explain things to you when they give you your bill. They tell you what all they see, and if they think something needs to be watched or brought in earlier. There's no problem They are very professional on telling us what's wrong or right. They don't charge too much. I don't have no complaints so far.
Description of Work: The did an oil change, checked the water, the hoses, and they rotated the tires.

They were great. No complaints. I've been back to see them for other things. I have a truck that I don't drive a lot. We take it on vacations. I needed an air conditioning charge so that's when I initially bought the deal. And then after that, I think I took it back in for maybe a belt or maintenance thing before we went on vacation. I thought that I bought a deal from them for air conditioning for $99 something like that. I don't really have very much memory of it so it must have went well. I went back at a later time. If I have a bad experience, I just don't go back. I think I needed appointment, both times I got it. They took care of it. They were thorough, professional. I give them As for everything. As for price, it was perfectly fine. Reasonably priced. When you go to those automotive places, to keep good mechanics, they have to give them a competitive wage. I have a lot of respect for that line of work. They are not cheap, but I'm sure they are fairly priced, competitively-priced. Everything was an A, otherwise I wouldn't have gone back.
Description of Work: I used ADS Automotive Diagnostic Specialties Inc. I did brought an air conditioning charge or something like that for a hundred dollar or something like that. I think for the air conditioning service, it was like $99 including freon.

Description of Work: Arizona Diagnostic Specialties recently replaced the water pump in my daily driver. As always, the job was done right the first time. | |I handle most of the maintenance on our vehicles myself, but Arizona Diagnostic Specialties in Chandler, AZ has been our go-to shop for several years for all major repair work. I keep using this shop because I never need to take a vehicle back for a do-over. ADS isn't the cheapest shop around, but the quality of work and my peace of mind are well worth the small additional that I pay for service here.

Came back with over $1200 estimate in charges. Approved about $900. When I went to pay the bill it was over $1000. Forunately I had the original quote, but the initial contact was rude and insisted I had the wrong numbers until I could show him in writing what he had quoted me. Another attendant approved the removal of the $40 worth of rags and shop supplies used (so warning you will be nickled and dimed on their use of shop materials). Will never use again.

They took vehicle in for diagnosis and informed me of their suggested solution. They turned the rotors using a new process. They actually 'turned' the rotors while they were on the vehicle. This process renews the brake surface and makes it smooth and even again. They worked on the parking brake which had become in essence non-functioning. This repair and the brake vibration were both successfully accomplished.

I took a car to ADS because they advertise as expert in difficult diagnoses. My car had a clunking sound in the suspension and long term alignment issues. 3 days and over one thousand dollars later, the car still pulls to one side and the clunking sound is just as bad as when the car was brought in. I could have taken the car to another shop and gotten the same or better results for $300.00 less and in one third the time. I was treated politely and ADS seems like a well-run shop, but the results were disappointing.

Sean, Dale and company once again did an outstanding job! This Honda Accord has been meticulously maintained since 1998 - I always went to a Honda dealership for my services. That was until I found most dealerships to be non-responsive and very expensive. I have used ADS before and I will continue to use them to service my vehicles. They guarantee their workmanship and are truly just nice guys!

Great customer service and honest repair. I needed to replace my brakes. I had two other estimates, both of those places said I needed to replace all four breaks and rotors. I was concerned because that is a lot of money. I checked Angie's list and found ADS, what a difference, I only needed front brakes. Dale was very nice and helpful. I also got an oil change and they changed a brake light. I highly recommend ADS.

I brought my 08 Nissan Maxima in to have an oil leak fixed. Received a call a few hours later detailing the $6000 in repairs (new radiator, engine repairs, and tire pressure sensor) my car needed. After laughing at that quote, I was told $1500 would fix the oil leak and make the car "safe". After doing a little research, I found that I could purchase a used engine with a three year warranty for $1200 or a new one for $2300; a new radiator for $100; and a tire pressure sensor for $40. I reluctantly paid the $50 diagnostic fee and picked up my car. Bottom line: outrageous prices and dishonest or uneducated vehicle diagnostic..

.I initially contacted the owner of ADS to see if they had the appropriate level of expertise to take on a custom street rod project. He had one of his lead employees, Ryan, call me to discuss my concerns. After the discussion with Ryan, I decided that ADS was the right shop for this type of project so I drove the car down and left it with them for substantial modifications as listed above. I told Ryan that I was not in a big rush to get the car back, but that I wanted to make sure that they were making continuous progress on the job and not just letting it sit. Over the course of the project I spoke with Ryan at least once per week and he would give me regular progress reports on how they were doing. On one occasion Ryan could see that I would be able to acquire new wheels off the Internet for less than he could provide them and he let me know so I could save some money. ADS did a very nice job of redoing my frame cross-member, installing a new Tremec 5 speed transmission and clutch setup, and new drive shaft. All materials and components were first class and the installation was very clean. ADS measured backsets and clearances and recommended wheel and tire sizes that would look nice but not rub. ADS removed my 4 barrel carb, fully cleaned it up, put new jets in and properly tuned the fuel-air ratio so the car would start better cold.
Description of Work: ADS replaced my manual 4 speed transmission on my street rod with a new 5 speed manual transmission. They had to fabricate a new cross member and drive shaft, install and test out the transmission. They also installed and calibrated a speedometer cable, rebuilt my 4 barrel carburetor, measured and sized the vehicle for new wheels and tires. They put new jets in my carb and retuned the fuel/air mix for better starting and drive-ability.

They ran it thru the flusher, but it was still contaminated some afterward. When I mention to the Mgr that I wasn't happy with the results, he offered to do it again (but only one more time) for no extra charge. When that was completed, I was very happy with the results, and how ADS had treated me. These guys are fair, professional, punctual, and competitively priced.

Like buttah. I can usually drop the vehicle off before work and pick it up after, sometimes the bigger jobs run into the next day but ADS will drop you off and pick you up. Like I said, the wifes truck runs smoother than it ever has.
Description of Work: Timing chain and motor mounts replaced on my wifes pathfinder. The truck now runs smoother than it did when she first bought it back in 2005. We only take our autos to ADS, they will give you straight information regarding your vehicle. We've dealt with repair shops that throw parts at problems in the past, this is not ADS. They will correctly diagnose your issue and tell you what needs to be fixed vs. what you might want to have looked at later. If you want an honest car repair shop (I know, right up there with politicians, lawyers, and used car salesmen), well in this case, it is not an oxymoron, they are the real deal. Customer service and honest work. Something that is very hard to come by these days.

I went to ADS after having an unpleasant experience at the local Acura dealer. The dealer had indicated to me that a number of things needed immediate attention on my Acura, despite the fact that I had just had it fully serviced at my dealer in Colorado before I moved to Arizona. I took it to ADS for a second opinion. The folks at ADS basically said that I did not need any of the service items done immediately and, in fact, did not find some of the issues identified by the Acura dealer. I chose to have one set of brakes replaced while it was in for the oil change. I then brought in my son's Chrysler because the garage started to smell of gasoline when it was parked inside. ADS discovered that the gas tank had a leak and needed to be replaced. They also mentioned that the radiator hoses were starting to wear, but that it could wait if I wanted to do that service later. I opted to have both services done while the car was in the shop. ADS provided transportation for me to and from my home.The service on the Acura was very reasonably priced. The service on the Chrysler was expensive, but mainly because of the price of the replacement gas tank.
Description of Work: I had two cars serviced here, an Acura and a Chrysler. ADS replaced brakes and performed an oil change on the Acura and replaced the gas tank and radiator hoses on the Chrysler.

Date and $ spent refer to current service, but I also used ADS last fall for more extensive service. The current visit was due to the power steering starting to whine on my Honda Pilot. I feared the worst and that it would require a replacement pump. They provided a quote for this that was reasonable. However, they called me later in the day to tell me that the pump did not need replacing and all they needed to do was replace the seal on the pump. Instead of paying the expected $400+, I was only charged $140 and it fixed the problem! The previous repair was to replace the front struts, additional suspension work, power brake flush, transmission and differential fluid replacement. All of it was general maintenance, but they did a great job, completed the work on-time for the price quoted. In addition, the shop is really clean and they are SAE and AAA certified. While I generally do much of the easy maintenance on my vehicles, I would definitely take my vehicles here again in the future for anything beyond my capabilities.
