I have recommended McCullough's several times to my neighbors in the neighborhood blog. I have used this company for many years and they are always helpful. It is great to have a garage you can trust.

November 4, 2020This place is a life saver. Great communication, great service, and very professional people. Eric worked with me through my whole repair. Kept me updated through out the process and fixed the problem on my car at a fair price. I will definitely make this my new place to go for all my car repairs and maintenance needs, along with sending my friends their way.

Eric has been my service manager for years. He is always professional and easy to deal with. He goes out of his way to take care of your needs and makes accommodations to the customer when needed. They will ferry me and my car to and from their shop (I live within blocks) and I appreciate that very much. Everyone at McCullough is nice, friendly and helpful.

May 2, 2021My experience was surprisingly excellent. I was greeted immediately before I could actually get out my car. Eric was professional and friendly. Eric Followed up with me has promised. I really like that Eric shares real honest timing/wait expectations.

July 20, 2020Great customer service! Eric and team did an awesome job coordinating their busy schedule with the schedule of my girlfriend and myself so that we would have a car during the work week and then trade off cars when the other was ready. They are extremely friendly and it felt like they had us as the customer in mind. Highly recommend!

I know for me one hard thing about choosing a mechanic is brushing off all previous notions I have about mechanics Potentially not treating my car how they would treat their own car. This place has done more than exceed my expectations. I got a phone call for every update, I got a thorough description of what was to be done and what was wrong, not only that, but where the dealership said it would take them two weeks to fix my car, these guys did it in less than 24 hours. I have never been happier to spend $300 in my life. Anything I need in the future, you can be sure I’ll bring it here.

September 10, 2020WOW!! An amazing experience! Traveled here from Kansas to apartment shop for my daughter who is relocating and my husband was unable to join A part was dragging under the car so we popped in to see if they could help. They were so kind and helpful. Restored my faith in this world. Good people do exist!!

July 1, 2020I received great service from this location! I called them about replacing a serpentine belt and they got it done for me the very next morning. It was quick, and cheaper than some other places that I had called for the same service. Eric and his team did a great job, and they were very nice! I will definitely return for any other auto repair I may need in the future.

July 13, 2021Eric at McCullough has been taking care of my family's [multiple] cars for over 10 years now. A Volkswagen, a Nissan, and 2 Acuras: They've done minor repairs all the way to major transmission replacements. Eric is trustworthy, honest, and tells you what really needs to be done versus what can wait. Their prices seem reasonable (although in fairness I haven't been anywhere else recently b/c I'm so pleased with them), they are timely, and always communicate what the car needs in detail. I can't recommend these guys enough!

I had a check engine light on Saturday afternoon, ended up being an engine coil pack needing to be replaced. It was obviously super busy and I knew I would need to leave it until Monday to get looked at. Staff was very informative and communication was excellent. Got it looked at Monday and ordered necessary part to come in the next day. Went ahead and did the spark plugs as well since I was nearing 60k miles. Picked it up after lunch with no issues. Seems like they do really well with the small space provided and very busy area right off 285

July 21, 2021This shop is the best. They did everything they could so I would have minimal time without my car such as having all parts ready before they scheduled the repair. They are super nice and no surprises on price. They opened up my bumper and found a part was damaged. They could have left it the way it and no one would have known but they were honest and did the right thing. I recommend 100%.
Graham Reifert
July 24, 2019Brian and the team were fantastic with handling my issue. In fact they discovered a major error which occurred when I had my last oil change done at a quick oil change place, which turned out to be the cause of my issue. They took pics of it and wrote out an explanation for me to give to the previous oil chance place. Because of their extra effort, I am getting reimbursed for the error. I highly recommend Brian and the team!

I own and automotive repair business in Jacksonville, but my wife lives in Atlanta and needed tires for her car, so I know good service and fair pricing in this industry. I chose McCullough because of their good reviews and they did not disappoint. They were very professional and took good care of my wife. I would highly recommend them and will continue to use them for her service needs.

I would normally recommend this business as I have been here a few times. I went there Friday for an oil change. However, I honestly didn't feel safe. They have signs that customers must wear a mask. There was only one employee wearing a mask themselves. All the others didn't have a mask on. I feel this is disrespectful to their customers. I understand it can be uncomfortable but it is essential during these times.

Quick and excellent service. I was turned away at my regular mechanic because he said he didn’t know how to do a transmission fluid change. This was my first time ever going to McCullough auto care, and I was very happy with my service. They were able to see me immediately and were patient with me considering the circumstances. Eric was great, and even matched the prices of another mechanic down the road. I will be back! Would recommend!

November 19, 2019Very respectful, honest, and professional. I was having issues with my headlights, and they fixed it for a reasonable price. They do a lot to ensure that you have a positive experience, and that you're not wasting your money on unnecessary parts or repairs. Top notch service, A+!

My parents and I have been taking our cars there since the beginning. Great, hardworking guys. The only mom and pop shop left in Sandy Springs.

January 2, 2022Have been going to McCollough’s for decades! Once I found them, I knew they were honest and professional. Not often one can say that about an auto repair place. They have helped me keep my older vehicles safely on the road for longer than I could imagine. I have always been treated with respect, no matter how large or small the issue, which is excellent and reassuring for an older woman.Highly recommend them!
Marti Griffin
March 16, 2022I was so impressed with these guys!! Family business and the guys are professional, efficient, and personable. They got my part quickly and fit me in so I could come while my kids were at school. They went the extra mile (no pun intended) to consult with another auto body shop to make sure the repair was stable. I will be coming back for all future auto needs and will recommend them widely.

Eric and Company are a first class operation! They get it right the first time in every time! They will pick me up and drop me off to make it 100 times more convenient. They treat me like family and look after my best interest not just their bottom line! These are the kind of people that I value doing business with

February 15, 2021I have used McCullough for maintenance on my prior vehicle and received great service. Recently I had to repair my front bumper - I received an estimate for repair services that was reasonable. The estimated turn around time was less days than other auto shops. The best part was, the staff (Graham) was accommodating with my schedule and the repair was completed as expected/on time. The work completed was great. I absolutely recommended McCullough for auto care services.

What Can Cause A Check Engine Light To Be On?
Here are a few reasons why the check engine light may be on in your Cadillac.
- Worn Out Spark Plugs. Spark plugs create the spark that ignites the mixture of fuel and air to create combustion and power your engine. Dull or worn-out spark plugs can misfire, which could cause your check engine light to turn on.
- Loose or Faulty Gas Cap. That’s right. something as simple as a loose gas cap can cause your check engine light to turn on. This can cause you to lose fuel from evaporation and is an easy fix to make.
- Issues with Your Catalytic Convertor. The catalytic converter changes carbon monoxide into carbon dioxide. When your catalytic converter isn’t working properly, you’ll experience a loss in fuel economy and performance. There are many possible causes for a failing catalytic converter, all of which can cause the check engine light in your Cadillac to turn on.
- Failing Mass Airflow Sensor. The mass airflow sensor is responsible for determining how much air should enter your engine. Issues with your engine will occur when your MAF (Mass Air Flow sensor) is not calculating air intake properly. This can cause your check engine light to turn on.
If your check engine light is flashing, that means you have a serious problem. If it’s on but not flashing, there is still an issue, but not as severe. In either case, we urge you to bring your Cadillac into our shop when the light becomes illuminated. Our ACE-Certified Technicians can perform a check engine light diagnostic on your Cadillac to find the root cause of the issue and make repairs as needed.
