    We had an issue with a splash shield dragging and overheating. We are heading back to Kansas this afternoon. They were able to fit us in despite being super busy & do a quick fix and sent us on our way in 10 minutes. So kind and amazing service!

  • Eric 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 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.

    Honest and fair price!!! I went in for 60k mile service. They said I only needed oil and cabin air filter changed. That is refreshing honesty! Saved me big bucks! This will be my new shop for my car service. ☺

    This 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%.

    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.

    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

    Always extremely professional. Willing to work with customers. Sadly, car repair is expensive but they have worked with me. Graham has been extremely helpful with issues my daughter was having with her car while we were at another mechanic in the area. We asked on Nextdoor for recommendations and McCullough came up numerous times!

    I 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.

  • I may have written one other recommendation in my of 50 years, but after doing business with Eric McCullough for 35 of those years it is time to write another one. He maintained and serviced my auto's, my wife, kids and employees for 32 of those 35 years. He has stood behind the work on everything he and his employees have done. He operates his business with great honesty and integrity. I highly recommend doing business. with McCullough

    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

    I 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.

    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.

    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!

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 Mercedes-Benz.

  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 Mercedes 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 Mercedes into our shop when the light becomes illuminated. Our ACE-Certified Technicians can perform a check engine light diagnostic on your Mercedes to find the root cause of the issue and make repairs as needed.
