I cannot rave about this shop enough!! Tim Hayali and his team are fantastic. From making sure I keep up on regular maintenance, like oil changes (and I need the reminders!!) to giving me accurate estimates on cost and timing when I need something fixed. Like on Tuesday, when I told Tim my car was making a weird popping sound when I turned sometimes. They found and fixed the problem and had me back in my car by the end of the day!! And I could feel the difference right away. This is a crew with high integrity and solid work ethic. I’m so thankful for them!

I love coming here! Going to get my car fixed without my parents has been overwhelming in the past as I am a young college student. However, I always feel right at home here and I know that I can trust that good work is being done for a fair price. Not to mention how kind the staff is. Definitely recommend coming here for every little thing your car may need.

I can’t say enough about the owner Tim, his honesty, and the fast service I received. Took my SUV in for what I thought was going to be a major repair, Tim checked my vehicle, realized it was just a loose voltage cable, tightened it up, and my vehicle is now back on the road, running great! Not to mention I wasn’t charged for the time it took him to diagnose and repair the issue. I will take all of my vehicles for repair to Certified Auto Specialist, the owner Tim, have definitely earned my business.

I have taken my car here twice now, I appreciate the respect and professionalism I received both times. They get straight to the point when explaining what needs to be done and they dont go digging for other issues to rack up the bill. As a single woman, I sometimes fear having to take my car to get worked on, but at the same time Im lucky enough to know more about cars than some, so I want to thank Tim for making it so easy when I need to get my car looked at and fixed.

My a/c wasn’t working anymore. Took it to Tim and he found the problem in 2 minutes. He fixed it up better than perfect! It now blows colder air than when I first bought it. Great service, Quick Communication, Great Price and Overall I’d give it a solid 5/5 stars!

Good honest cool guys. Friendly and professional. Highly recommend.

Great customer service. They were able to get me in the next day and now my AC runs perfectly

Tim from Certified auto specialist took great care of us and our car needs. Transmission in my car went out and he got us in immediately and 3 days later he had my car completed. They are quick, friendly, and did a great job. We will use them again.

Owners a great guy.Service is good thanks.

Thanks. My car needed some repair work after all that snow that we had recently. I took my car to Tim and he was looking at it within a few minutes. I really appreciate having someone I can trust my vehicle with. The only person I will go to if I have any issues! Thank you.

Thanks so much to all the guys for their hard work on my H3Hummer. I am very pleased with all that you did to get it up and running again. I would definitely recommend them and will use them for all my auto needs.

Tim was very informative and also let me know of actions to take to help prevent my issue from happening again. Turn around was quick as well!

Great service… would recommend to anyone

Broke down while passing through town. Tim bumped me to the top of the list and got me back on the road. Thank you so much!

Broke down while passing through town. Tim bumped me to the top of the list and got me back on the road. Thank you so much!

HONEST + REASONABLEI found this little gem via recommendations on Nextdoor. Honesty is lost on most businesses these days - refreshing to find one that is! I would give them 10 stars if I could.

I own an older model auto with 107,000 miles that needed several repairs and updates . Tim and crew did an excellent job making it run like new at a very fair price. Tim and all of his employees are certified and professionally trained. I highly recommend Certified Auto.Joe Carey

Great place, honest and care about you as a person. They do not hassle you about everything. They tell you how much it is going to cost before the repairs and are great about making sure it is done right.

Tim was exceptional and very professional. We had previously received quotes to repair our 2008 Toyota tundra that exceeded $3,000. Tim chose honesty and educated us on how and why the truck was running in limp mode. The cost to repair and buy a part for it was only about $600. He even followed up to make sure that the truck was running okay.

This team of mechanics came highly recommend by my neighbors. We are new to OK so we rely heavily on the referrals of the friends we have made thus far. We were pleased with how quickly we were called back with an estimate of the work needed and they had everything done same day! Super convenient and professional! My car is driving like a dream again and we have found our trusty neighborhood mechanic! Thanks y’all! Stoked to have found this team!

Tim and his crew are awesome! Brought my son’s Tundra in for him to look at. He had it fixed really fast and a very reasonable cost. Please do not hesitate to take your vehicle to them. First class place, super clean shop, very professional!

Kyle & Tim have taken car of my Scion IQ since I purchased it. They have charged reasonable prices for service & always have quick turnaround time. I have never had to wait more than 30 minutes for my car to be serviced. They have never tried to upcharge, which I greatly appreciate. I have put 50k miles on my little 1.3L engine in the last year & they have kept it running smoothly. I highly recommend them to anyone looking for a solid auto maintenance crew.

Our 2003 Honda CRV drives great and no over-heating. New struts makes it feel like a new car. We appreciate your time and expertise and great customer service. We love this little car and you guys gave it the respect it deserves. Well be using your services again in the future! Thanks, Tim and crew!!!

Just moved into Oklahoma it’s really hard to find a honest mechanic that is willing to fix your problem and not just wanting to up sell thank you so much for the compassion and honesty that you provided for us we will be life long customers

Called in and spoke to Tim (owner). We spoke briefly about my issue regarding the thread on my oil pan, and he wanted me to bring it in to see if he could fix it. The next day I went in, we went over our options and he set proper expectations about what needs to be done. Unlike another shop we went to where the only option was to replace the part but Tim gave me the option of trying to repair it. Its good to hear theres still mechanics who will do the job rather than try to make an extra coin. Thanks Tim! Ill be coming back.

They wont let you waste your money on things that wont really fix your car. Even if that news isnt good news, honesty is all people really want. My family and I appreciate these guys and we will continue to come back. Thank Tim and CAR staff!

Tim is always awesome! He provides you with the best customer service and prices. I recommend this location.

I had my vehicle towed to Tim and the team, and they went above and beyond. My vehicle is older and the part is not made anymore. Tim’s team was able to complete the repair for much less than I expected. It’s nice to be able to trust someone with my repairs. This is the second great experience with these guys. I highly recommend...they get the concept of repeat business versus making everything on one repair. Thanks again!

I appreciate the work that Tim and his crew put into my vehicle. It was fast and affordable. Ive done a lot of research and Certified auto specialists has one of the best reviews in okc. I’m definitely gonna be using them in the future. They won’t disappoint 👍🏽

Very clean and outstanding customer service with reasonable prices. This is the second time Ive used them. My new go to repair shop. I HIGHLY RECOMMEND!!!

Short version- Fast! Fair! Polite! Clean! Comfortable!Long version- This was my first time having work done here, but Tim & staff made me feel like family right off the bat. The waiting room was far more comfortable than most auto places- the weather outside was 90+humidity, but I forgot all about that after 30 seconds in the beautifully cooled lobby w fantastically comfortable furnishing. There was cold water in a mini fridge and fancy coffee, places to charge my phone and everything was spotlessly clean. That lobby is my new #living room goals! I would have happily waited another hour or five, discovering all the hi-tech amenities seamlessly incorporated into the decor, but I never had the chance- my car was all done in barely 30 minutes! And I didn’t even have an appointment! The price was exactly what I expected, there was no type of up-sell stuff whatsoever (which really deserves its own paragraph) other women will recognize how rare this is. My car is running great, I’m so glad I found this place. Honestly, I’d rather tow my vehicle 200 miles to have these guys work on it than put up w nonsense and bad vibes of other shops. 100%. 5 stars. Two thumbs up. Can’t recommend this shop enough.

Honest, reliable, excellent auto repair work.

Tim and his staff are great! They figured out what was going on with my car quickly and had me back on the road in no time. I really appreciate all their help and will only be taking my car to them now!! Thanks again guys!

Always friendly and courteous. Answers questions to where you understand. Not pushy and goes the extra mile. Highly recommended will not go to anyone else.

Tim and his has gain my business for life. After spending thousands at another repair place to fix issues with my sons Jeep. Tim was able to fix what they couldnt. So if you want something done right highly reccomend you take your vehicles there.

My car was making lots of noise and I had it looked at by another auto shop that was recommended to me. The other shop told me there were major repairs that would need done that would ultimately cost more than the car is worth, as well as several other problems. I brought it to Certified Auto Specialists and they were able to get my car in quickly to look at it and found the source of the noise, which hadnt even made it on the list of problems the other auto shop had diagnosed. The next day my car was being fixed for a very fair price and its up and running again! The customer service was great, they told me what problems were urgent and other problems to keep an eye on in the future, but didnt do anything without my approval first. I would highly recommend!

Fantastic service. I go in to get an oil change not knowing if they had any time to do. Walk in and Tim says sure, we can do it now. So, I’m sitting there and realized I left my credit card at home. I tell him this and he says....no problem, just bring it back later. Who does that? Very friendly shop. Thanks!

Tim and his team did a wonderful job on my Infiniti. He provides an honest assessment and recommendations. He is very knowledgeable and takes time to explain your options. Honest service and honest pricing. I paid $1000 less than what the dealership quoted.

I had a great experience with certified auto specialist. Tim went out of his way to ensure I wasnt spending money unnecessarily. He explained everything and made sure I understood the work that would be done on my car. He also followed up a few days later to make sure my car was doing well. If I need more work on my cars in the future this is where I am going.

Great service. Certified Auto Specialists worked on our breaks and AC. They were prompt, communicative, professional, and did high quality work. Tim was great, answered all our questions and explained the issues with our car. Several days out, we’ve had no problem. I recommend!

Tim and the team at Certified Auto Specialists are rare find! Ive been to many mechanics over the years in numerous states... this group is one of my favorite. We had taken my Wifes Elantra to numerous mechanics in the past few years because of battery issues. We knew there was a parasitic draw somewhere draining the battery after the car was turned off.. but mechanic after mechanic could never find the issue. Once again, car battery dead for no reason.. so we took it here. It took their specialist, Kyle, a bit more time than usual.. but he sure as heck found it! Their determination and thorough inspections of the vehicles allowed them to see what others couldnt. Car is back and running fine. This is a great group, they are knowledgeable, professional and have fair prices. Ill be back here over and over.. they also did my timing belt on my Honda Pilot for about 15% less than others were quoting me... so even more of a reason to come in!

I’m so thankful my neighbor referred me here! I was in a pickle & Tim was about to take care of me same day & at a reasonable cost! You don’t know how thankful I am! Please consider Certified Auto Specialists when needing your vehicle worked on! You’ll be happy you did!

Great service, Tim had his guys install a front end level and shocks on my old 3/4 ton work truck. Most shops will Not even mess with leaf spring suspensions. I brought him the parts and they did it no problem. He did not even charge me for the extra labor involved with taking out rusty bolts. I’ve had him do a similar project on my wife’s GX470 Lexus. Great shop great prices. one stop does it all. Will Use them again and again for sure. Thanks !

Tim and his team took great care of my vehicle for less than I expected to pay. Friendly, quality service, timely repairs and affordable prices. I highly recommend them for any service needs.

Excellent service. Tim was great in getting my car in quickly to get checked out. Service was quick and seamless. Tim reaches out to me several times to make sure everything is working fine! Now my go to shop.

Great service, plus fair/reasonable pricing. Quick turn around as well. Very pleased. So glad I found them.

Tim and his team did a fantastic job! I felt comfortable to work with them from first interaction. Their work is great and the price is reasonable.Would recommend, will be back if our cars need it.

My family has been using Certified Auto Specialists exclusively for the past four years. Tim, Kyle, and the rest of the staff have always explained any issues related to our vehicles prior to beginning any service, repair, or maintenance. I believe Tim runs a fair and honest shop, and recommend his services to anyone searching for a mechanic. His customer service is second to none.

Staff is very courteous and explain everything thoroughly !! Wont take my cars anywhere else! They have been great si ce the first experience . Tim and the guys getter done!

No one likes car trouble; but with the Certified Auto Specialists it was a smooth transaction. I truly appreciate the expeditious service, professionalism and ease of communication. Thank y’all. It was a pleasure doing business with ya!

I have owned two Toyota vehicles and I wont take them anywhere besides Certified Auto Specialists. Tim is very knowledgeable about my vehicle, doesnt try to up-sell, and is very helpful with any questions I may have. The service is always friendly and efficient and I dont have to worry about my vehicles performance until its time for the next appointment.

I’ve been very impressed over the years with the people and workmanship at Certified Auto Specialists. My wife and I have been taking our vehicles to Tim since he opened his shop years ago. The mechanics are honest and dedicated in doing a thorough job. When we pick up our vehicles, he goes through the bill and answers any questions. We wouldn’t take our vehicles anyplace else.

Great service, quick and reliable! Would highly recommend and will use again.

My wife and I moved to Edmond a little over a year ago. A family member recommended Certified to us when we had a problem with one of our vehicles. We met Tim at their old location and felt good about what he had to say, so we left our vehicle with him. He was very diligent in communicating with us concerning their diagnosis and recommendations. We picked up our car the next day, and the charge for the work was actually LESS than what he had quoted to us. This made me a believer in Certified, Tim, and his work crew. They always exceed my expectations and go above and beyond to serve their customers.

Found my mechanic. Great team who does honest work for the right price. Navigator was dying on way home during a 15 hr drive. Tim and his team found the problem and gave me a best case number and worst case. They knocked it out and it was the lowest possible fix. That is refreshing.

Tim and the crew always take great care of our Jeep.

Tim and his staff always do a great job. My daughter’s car drives like new and gives me a great peace of mind. Will continue to bring our cars there.

Certified Auto Specialists have done an excellent job on my BMW. They have done repair and preventive maintenance for me. I was a little concerned after purchasing the car that I may have trouble finding a shop that I could rely on to do, not only a good job, but an affordable one also. I dont worry anymore.

I am so happy I was referred by a friend! I won’t go anywhere else now. They took such good care of me and handled several issues I had right before a road trip and I appreciated the hard work on short notice so much.

Was shopping for a new car and stumbled into what appeared to be a great deal. Hadnt set up an appointment the day before as is standard for most shops- just had called that same day I found the car and was at the dealership in a tight spot not wanting to lose the deal. Tim somehow fit me in and they spent 20+ minutes inspecting all over the car. All the while Tim made great small talk and was incredibly friendly. They have a fantastic reputation as technical experts and I can vouch for their business demeanor. Will definitely give them a ring in the event something unfortunate happens with my car.

Great quality work and straightforward feedback - would highly recommend this shop for all things automotive!

Tim and his crew are the best! I wouldnt take my cars to anyone else! They are more than fair in their pricing, always efficient and the free inspection on used cars before you purchase is a huge bonus. I have referred several friends to Tim and will continue to do so .

Great place. Good work and in a timely manner and affordable. the owner even checked in with me a few days later to make sure everything was going well. I will use them again.

I live in Moore, and I drive to Edmond to have them work on my car. I have been a customer for several years, and I appreciate that they are honest, reliable, fast at finding the problem and fixing my car. Tim and his team really knows this business. I really feel safe driving my car after they have service it, whether changing the oil or fixing something major. I highly recommend Certified Auto Specialists.

Tim gave me a great deal & kept me from driving my unsafe vehicle on the road. Very professional.

ASE certified master mechanic. Above and beyond required level of service. Very thorough diagnostics and repairs. Took their time to get it right the first time. Communication throughout repairs was exceptional. Highly recommended!

Great service. I can alway rely on Tim and crew to provide the best service and repairs around. They will also work with you on what repairs are needed right away and what can wait. I would recommend them to friends and family alike.

Tim was super helpful and knowledgeable! Kept me up to date with prices and problems, surpassed all expectations! 10/5 would recommend!!

UPDATE: the review below was from 3 years ago, and I still feel the same way! Thank you Certified Auto!I truly enjoy taking my vehicles to Tim at Certified Auto Specialists because I know my vehicles will be taken care of properly. He is a stand up guy that can be trusted, one who takes care of his customers! Whether it is an oil change or something more dire, he will take care of you.

I was referred to CAS by a friend when I needed a new transmission installed in my truck. I called all around town to get prices and Tim had the best price and the referral going for him. Tim and Kyle were both great. They let me choose the day I wanted to bring in my truck so it worked around my work schedule. The best part is they had my truck done by the day they promised it and it runs great. I would highly recommend this shop for your auto repairs. They definitely have a long term customer in me.

Excellent and honest service, Tim and his team are the best at what they do! I would definitely do business with Certified Auto Specialists again!!! I strongly recommend them!

Excellent and professional service, I was seen right away and charged a fair price. I will definitely be back the next time I need work done on my truck.

Certified Auto Specialists are the real deal. They do it right for the right price! They are very knowledgeable and their customer service is excellent!

Tim and his team are great! They have always met or beat the big name shops in Edmond! Their honestly and quality of work will keep me coming back with all of my vehicles. I highly recommend them for all your vehicle service needs!

Tim and his guys did a great job on my truck. The heater was not working. I was worried that the heater core would have to be replaced and that is very expensive. One shop I talked to said it could cost $1500+. I dropped my truck off and they fixed it in less than a day at a fraction of what I feared it would cost. I could not be more satisfied with my repair and the service. This shop is honest and more than fair. If you need your vehicle repaired or serviced this is the place to go. Thank you Tim for the excellent service.

Tim and his team are amazing. Great customer service and always extremely thorough work.

This was the best service I have gotten when something has gone wrong with my vehicle. The service was timely and the cost was well under what was expected. Certified Auto Specialists is 100% recommended. Thank you, Tim.

Reliable mechanics who dont over charge or over diagnose your car problems. Best customer service I have experienced. These guys will be my mechanics as long as I like in Oklahoma.

I have taken 3 different vehicles there and they took care of me each time at a fair price and without pushing unneeded repairs. Work was complete on and on budget as promised

Tim and his team at Certified Auto Specialist are great! Their integrity is outstanding...too long to discuss details - however, they have saved my husband and I from unnecessary expenses that other auto shops tried to charge us. They are great at what they do and treat their customers with the highest level of respect. We have taken 3 vehicles to them and each time all problems were solved and they did NOT come up with the usual auto shop and we found x, y, and z that you should also get fixed today. Again, I cant speak highly enough of Tim and his team in regards to their skill, customer service, and prices!!! ~Mary Bost-Owens

Professional, courteous and honest! Tim and his staff are terrific!!

We take all of our company trucks to Tim.Great customer service, always happy with the repairs.Would highly recommend Certified Auto Specialists.

I heard about Certified Auto Specialists from a friend. He kept telling me about Tim and how good he was in fixing his cars. I didnt think much of it over the next few months but I needed some work done to my Chrysler 300C. My car was trying to run hot and i thought maybe it was my thermostat but wasnt sure. I decided to let Tim look at it and also my other problem with my front end alignment. Tim diagnosed the problems and fixed it. My car rides really good now and thanks Tim for everything. I will highly recommend sending your car to Certified Auto Specialists and Tim and company will take good care of you and your car.

Tim and his mechanics are honest and knowledgeable. Hes saved us a lot of money and hassle. I wont take my Infiniti anywhere else.

This is my go to place! Highly recommend them!

I learned about Certified a few years ago when looking for an alternative to getting service and maintenance from the dealership... and what an upgrade it was. I have 2 older model Nissans, and have had a few bad experiences with other repair shops. Tim and Kyle have earned my trust and I highly recommend

Have a Chevrolet HHR that started intermittently putting message on screen- power steering. Made appointment w/dealership & was given a very expensive price quote, but scheduled appt. because of recalls on HHR. Drove to work next am & power steering message came on in the middle of turn and I wasnt prepared and almost had single car accident...decided to find second opinion & remembered articlein Edmond Outlook about this business.Absolutely thrilled I contacted them...explained problem & I was able to leave car & repairs were made & was able topick up car after bus route. I have received text asking if car is functioning properly & told Tim....YES!!! Awesome work!So happy to have found awesome auto shop!!

I have been here twice and have been impressed with the level of service, price of services and the courteous manner in which I am treated. Top notch business!

Tim and his crew are the best in Edmond. The only place I will ever take my personal and company vehicles. Fast, reasonable, and great customer service.

These guys are amazing. Lets be honest, anytime your car breaks down its a stressful experience. However, having Tim and Kyle as my familys auto mechanics makes a horrible situation so much easier. I never have to worry about being lied to with these guys. They let you know your options up front and you can tell theyre doing their best to look out for their customers best interest. Theyre honest, caring and truly make me feel safe when my car is returned to me. Thank you guys for taking care of us and going that extra mile.

Very honest and knowledgeable shop. I won’t take my car anywhere else! It’s hard to find these qualities in an automotive shop now a days.

I came in with my car limping with a dozen check engine error codes. They quickly diagnosed the issue, fixed it, and returned it to me in about a days time. Pricing was fair also. Thanks!

Tim has accurately diagnosed every issue with my sons car. He is upfront and honest. We wont go anywhere else.

Always so professional and do a great job. If its not quite right they get it back in quick and get it taken care of!

I had been at a business nearby and stopped Certified to see about an oil change on my Acura. They did it right then (which I needed) and I was extremely pleased at the price. I’ll with be my regular go to for all my vehicles now.

I had bought a used car from an individual and had no info on the car. Took it in to have tim and his crew look at. Within an 2 hrs they had let me know what was going on And actually showed me where the issues was while it was on the lift. To me thats a big deal as i am a mechanics daughter. With that being said i dont let just anyone touch my cars. I will be coming back with any and all issues including a simple oil change! If you want someone you can trust call tim :)

Recently, during a warm spell, I had an air conditioning problem with my Grand Marquis LS. Not only was it blowing hot air, but the blower motor was making noises and the fan switch was stuck on high. I took the car by my local Goodyear store and got an estimate that blew me away....and that was just to fix the air conditioning, not the blower motor nor the fan switch. My gut feeling was a cavalier take it or leave it attitude from Goodyear. I heard from a friend that he had used Certified Auto Specialist on North Lincoln Blvd. and had been treated very well. I took the car by there and talked to Tim the owner. My first impression was of a knowledgeable and very courteous guy, with a clean shop, work area, and reception area. Tim explained to me very clearly what was causing the cooling problem, and promised to look into the switch and blower motor also. I made an appointment and dropped the car off a couple of days later, telling Tim to take his time, knowing he was busy. Two days later Tim called and said the car was ready to pick up. I had expected, and was prepared to wait a week or so before the repairs could be made. Not only was Certified Auto Specialist fast, but Tim was able to also fix the fan switch and blower motor at the same time, and was WAY UNDER the quote from my local Goodyear Dealer. To say I was pleasantly surprised was an understatement. The air conditioning is now good as new, and at a very reasonable price I could live with. I found Tim and his knowledgeable mechanics to be fast, fair, very competent, and great guys to know. I am very satisfied with the work, and now have a place that I feel will take good care of any further automotive needs I may have. I would highly recommend Tim and his staff at Certified Auto Specialist to any and everyone, especially to women who are often taken advantage of by unscrupulous mechanics and dealerships.Tim, thanks for the cold air....youll get my business again!Joe Austin-Northwest OKC

Trustworthy. Professional. They will take care if you for sure.

A little slow, but good service. I found it a little hard to communicate with the owner, but in the end I understood what he was explaining. I might go back.

Tim toook n my Durango with zero notice, callled my extended warranty and had my SUV ready next morning. All with a smile. Incredible job, great people!!!!!
