A Tribute to Roderick L. “Rod” McCullough
Founder of McCullough Auto Care & Tire

With heavy hearts, we announce that the McCullough Auto Care family has lost our father, founder, and mentor. Roderick “Rod” L. McCullough passed away peacefully on February 1, 2025, at the age of 86. A man of integrity, quiet strength, and entrepreneurial spirit, Rod built a lasting legacy in both business and community, leaving behind a life marked by dedication, service, and love for his family.

Roderick moved to the Atlanta area from his native home in Anderson, South Carolina, in the 1960s, focused on starting his family business. He became a successful businessman during the 1970s, owning and operating several Shell service stations throughout the area. In 1969, he founded McCullough Auto Care in Sandy Springs, Georgia, with just $1,200 and a clear vision. Over the decades, Rod grew the business into a trusted name, known for its honest service and family-oriented values.

Rod found joy in life’s simple pleasures. He loved long bike rides, peaceful walks along his favorite beach, and cheering on his beloved Clemson Tigers. Above all, he was most proud of his family. He celebrated their accomplishments with pride and never missed an opportunity to remind others that “family is the most important thing in life.”

Rod’s legacy lives on through his children and grandchildren, many of whom have followed in his footsteps and contributed to the family business.  Through every customer served, every child mentored, and every value passed down, Rod McCullough’s legacy endures — a testament to a life well-lived and a family business built on trust, hard work, and heart.

    Just wanted to take a moment and acknowledge the wonderful people at this company. They’ve helped me out a number of times with quick repairs, honest work, and fair prices. They are good people and the shoot you straight every time. They make sure you understand why they are doing what they are doing and exactly what to expect. Someone give Harrison a raise. I’ve called him a number of times and he’s never failed. I’ll be a customer for years to come.

  • Just completed my first service with McCullough, and I am impressed. I have a CPO 2013 Lexus ES 350 which I have always taken to the dealership for service for the past 8 years. At 150K, I thought it was time to explore less expensive options and more convenient. I interacted with Harrison, who is a true professional and easy to communicate with. Rather than "just do the recommended service", he suggested an oil change and complimentary inspection and then determine what, if any, additional work might need to be done. There was a relatively small amount of additional work which made sense given the age and stage of my vehicle. Pricing was discussed up front and was fair. I live close so after dropping my car off, he and Daniel came to pick me up when the works was done. In this day and age of, as Clark Howard says, "non customer service", I have found McCullough to be the exception that proves Clark's rule. We will be doing more business with them and highly recommend. Adding this after another visit to McCullough NAPA in January 2025: This is my second experience with McCullough and this was just as good as the first one. Brought in my wife's car for an oil change and overall evaluation. Harrison advised we did not need on oil change...how about that, a car place advising what's in the best interest of the customer and not an opportunity to charge for another service. Harrison and team checked out the car and advised us on the vehicle, which will go a long way to our determining if we keep or trade in. The charge was fair and reasonable. We'll be back soon for a service on our other car. Keep up the good work McCullough! Went in for a third experience and Harrison was professional and helpful as always. He pointed out some items to be on the lookout for not pressuring for immediate action. Good to have a heads up for what might be coming down the road. Will back on 6 months, or mileage, for another oil change and tire rotation and overall "health" check.

    My 2012 Genesis needed a new battery, so I looked at various sources and found McCullough NAPA Auto Care reviews to be reassuring and helpful. I am very glad I went there. The lot is crammed with cars to be worked on or awaiting pickup after being serviced, but the gentleman directed me to park near the service doors after I explained my need. He immediately escorted me inside, I completed a work order, and he showed me to the waiting area. I'd say the work took maybe 30 minutes, and the service agent with whom I'd spoken on the phone about a battery, called me to the desk and handed me the keys, thanking me for coming in and directed me to my car waiting in front of the service area. Everyone was very professional, friendly, and careful to explain problems found in customer vehicles, as I overheard with several people who had come in while I was waiting. I would say, aside from friendly, honesty was my strongest impression of this family run business, and I will be back!

    This was our first repair at McCullough NAPA Auto Repair. They came highly recommended by several neighbors on the Nextdoor app. We had an excellent experience and the price was very competitive. For example, our oil change is usually around $90. and it was around $75. Eric, the owner, called with a quote for the repairs and found an issue with the oil that could have damaged the engine. I was grateful for that and decided to let them do their multi-point inspection. They found a few small issues none of which were super expensive. Then Eric, the owner, called at every milestone of the repair. He was approachable yet professional and to the point. I was always informed on the progress of their work and the car was ready quickly. I would recommend

    I’ve come here twice before and was happy with the work. But when picking my car up on the third visit I learned that my bill was more than double the price that was initially quoted to me (+$2,800 instead of $1,300), which was a substantial difference for me. The shock of learning this when pulling out my wallet to pay at the front-desk was very embarrassing to say the least! They did a good job, but my advice if you bring your vehicle here is to make sure to learn more about your quoted price. In my case, when I asked the cost, I was quoted roughly $1,300 but apparently, as my bill would show, I was only quoted the cost of “parts”. If this distinction was make known to me then I would have made an informed decision based on the price of “labor” as well.

Signs Your Alternator Needs To Be Replaced in Atlanta

Your alternator is a critical part of your vehicle’s electrical system, supplying power to essential components while keeping the battery charged. When the alternator starts to fail, you may notice warning signs that indicate it needs to be repaired or replaced. Ignoring these symptoms can leave you with a dead battery and a car that won’t start.

Here are the most common signs of a failing alternator:

1. Dimming or Flickering Headlights

One of the first signs of alternator trouble is inconsistent or weak headlights. If your lights dim while idling or flicker when you accelerate, it may mean your alternator is struggling to provide enough power. Since the alternator directly powers the headlights, any inconsistency in brightness is a sign of electrical issues.

2. Warning Battery Light on the Dashboard

Your car’s battery warning light doesn’t always mean the battery is bad—it can also indicate charging system problems caused by a failing alternator. If this light comes on while driving, your alternator may not be supplying enough charge to keep the battery and electrical components running properly.

3. Difficulty Starting or Frequent Stalling

A failing alternator won’t provide enough power to keep the battery charged. This can lead to a slow crank when starting your car or a complete failure to start at all. If the alternator completely fails, the engine may stall while driving, as it won’t have enough electrical power to stay running.

4. Electrical Malfunctions (Power Windows, Radio, A/C, etc.)

Since the alternator powers all of your car’s electrical components, a weak alternator can cause malfunctions in power windows, door locks, dashboard lights, radio, air conditioning, and more. If multiple electrical features are acting erratically, it’s a strong indication that your alternator isn’t supplying enough power.

5. Unusual Noises (Grinding or Whining Sounds)

A failing alternator can make grinding, whining, or squealing noises due to worn-out bearings or a loose serpentine belt. If you hear these sounds coming from the engine bay, it’s best to have your alternator inspected before it completely fails.

6. Burning Smell Under the Hood

Overworked alternators can overheat, causing a burning smell similar to hot wires or rubber. This can be due to friction from worn bearings or a serpentine belt slipping on the alternator pulley. If you notice this smell, it’s important to have your alternator checked immediately to prevent further damage.

7. Dead Battery (Even After a Jump-Start)

If your battery keeps dying, even after a jump-start, your alternator may not be recharging it properly. While a bad battery can cause similar symptoms, if you’ve recently replaced your battery and the issue persists, the alternator is likely to blame.

If you’re experiencing any of these signs of alternator failure, McCullough NAPA Auto Care in Atlanta, GA, can provide a thorough inspection and expert repair or replacement. Give us a call or schedule an appointment online to ensure your vehicle stays powered and reliable.
