Good, honest, and fair shop. If you are in sandy spring, I would not go anywhere else. Family owned and operated - take care of their customers and their crew it seems. 6 stars

Eric was amazingly helpful to work with. Great communication around the whole process. He was great about calling out things that could be done without being pushy about doing them. Would highly recommend!

I have used McCullough Auto Care for more than10 years. I needed a reliable auto maintenance service because I commuted weekly to Birmingham. One of the nice things about these guys is they listen when I mention an issue with the car, go over their inspection results of my car and review my bill in detail. I have never been disappointed in their service or the cost of the service I received.

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.

This 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.

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!

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!

Great service! The entire team is so friendly and helpful. They were able to diagnose the issue and stayed with it until the problem was resolved.

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 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.

Great 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 really cannot count the number of times these brothers have taken care of me, my family and all our various vehicles. We have been loyal customers for more than 20 years! They have done everything we have needed on cars, trailers, used car evaluations for purchase, tank drops, and all the basics. They are very trustworthy and will give you a honest answer on everything and a reasonable estimate on what it will cost to resolve it. They are super busy, so plan to wait a day or two longer than you might somewhere else, but it is worth it!

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.

This place is exactly the kind of service you come to expect. Great service, timely, and they never assume I don’t know what I’m talking about because I’m a girl.

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.

Why Is My Check Engine Light Flashing?
Here are a few reasons why the check engine light may be flashing.
- 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 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 or blinking, 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 vehicle into our shop when the light turns on. Our ACE-Certified Technicians can perform a check engine light diagnostic and find the root cause of the issue and make repairs as needed.

Have you ever experienced a rough-running engine or felt your vehicle losing power? This may be due to an engine misfire. An engine misfire occurs when one or more cylinders fail to ignite properly during combustion. This issue can significantly impact your vehicle’s performance and should be handled promptly to prevent further damage.
The engine air filter in your car keeps dirt and debris from entering your engine. Much like you, your engine needs clean air to function. A clogged air filter can cause your engine to work harder than it needs to.
Does your car make a loud noise while accelerating? Acceleration should be smooth and steady. If your car does make a loud noise when you
