    My 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.

    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

  • We have been depending on McCullough's at least since 1997, when we purchased a home only a few blocks away, walking distance really. Had our emissions test a few days ago and want to acknowledge Jack, who completed the tests quickly. I asked him to determine why the backup camera was not in the proper position. It took a bit of time and ingenuity to get everything right. Thanks Jack, for the excellent service.

    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.

    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.

  • This has to be the best shop in town! When I got my car fixed the last time, It drove live new. I've never been so happy to get my car fixed in my life. They were very friendly and honest. This will be my go to place from now on. Not too far from my house which is a huge plus but even if it were, I'd be game to making the trip. Thanks for being honest and giving great service!

    Able to fix issue with my 2011 truck other shops could not address- very hard to diagnose mechanical issue another reputable shops couldn’t figure out. Good prices, done on time, and with expert mechanics. Will have them work on all of my vehicles and highly recommended. Support a family owned business for a change!

    I live in Brookhaven and work in Duluth and pass dozens of auto repair shops on the route. I will forever go out of my way to go to McCullough. This is hands down the best repair shop I’ve ever been to. They are honest, kind, and treat each customer with the utmost respect. I’ll never take my cars anywhere else!

  • My vehicle was on the verge of breaking down while I was in Sandy Springs for work last week (I live in a different town), and my boyfriend had determined that it was a problem with the alternator. He helped me find McCulloch Auto Care, which was right down the street. We'd noticed the good reviews, and we took a chance! The staff is super friendly, professional, and kind. They were able to confirm our suspicions about my car's specific issues, and took us as soon as they could. I was so impressed with their customer service. They really went above and beyond to meet my repair needs, had a fair price, and worked quickly to repair the issue. I almost wish I lived closer just so that I could have my car serviced here more often! Great family owned business.

    Eric was amazing from start to finish. I chose this shop for my repair based on previous reviews & I'm glad I did. He made sure to, in my opinion, go above and beyond with his politeness, as well as helping to make the process smooth and to try to save me as many coins as he could, while still getting done what was needed. Very happy with this visit

    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!

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.

  1. 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.
  2. 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.
  3. 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.
  4. 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.
