Broke down passing through Brunswick?
Brunswick sits on the road between Florida and the Carolinas, and travelers a long way from home end up on our lift too.
A Friday afternoon on Jekyll Island
Visitors heading home to North Carolina heard a loud squeal from under the hood a couple of hours before closing. We arranged for them to be picked up, ordered the parts from their description, then found and replaced the broken pulley so the belt was running again, instead of them being stuck for the weekend.
A check engine light on the way to Florida
We took the car right in, ran a diagnostic check and road tested it thoroughly. It was most likely the fuel sensor reacting to a little bad gas, and fine to drive home.
What we work on
Come see us for all your automotive needs. Here's the work we do most, written the way we'd explain it at the counter.
- Diagnose
Diagnostics and check engine lights
We run the diagnostic check, road test the car thoroughly and tell you plainly what the light means, including when it's fine to keep driving.
- Repair
Belts, pulleys and under-hood noises
Loud squeaky noise from under the hood? We find the broken part, like a pulley, order it and get the belt running again.
- Cool
A/C checks and cabin air filters
Weak air on a hot Georgia day? We take a look, and sometimes it is just the cabin filter.
- Repair
Wheel bearings
New wheel bearings put on quickly, with the car back to you the same day.
- Measure
Dyno testing, four-wheel drive too
Our dyno can test four-wheel-drive vehicles, so your SUV gets real numbers, not guesses.
- Perform
Performance work
Performance is in our name. Bring us the build you care about and we'll treat it that way.

Not sure what that noise is?
Call and describe it. We'll tell you honestly whether it needs us today.

Not every dyno can test four-wheel drive. Ours can put four-wheel-drive vehicles on the rollers, so you can see what your build really makes.

“Had my SUV dyno tested on one of the few dynoes that can test 4-wheel drive vehicles. None were working or available in the Jax area. Nice folks, took their time but got it done and I was happy about the results (almost 600 horsepower!) It was a hell of a hot day, I didn't get the E85 mix right, and it should have made almost 625 hp. Still... One of the few 4-wheel dynos available in the Jax region and they put me on the dyno 1 day after I called! Thanks.”

“If I could give them a 6/5 I would. On a Friday afternoon within couple of hours of closing, our SUV started making a loud squeaky noise from under the hood. We quickly learned that we should not drive the car at all. We were on Jekyll Island and were trying to drive back home to NC and with auto shops closing within hours for the weekend we were running out of time to see who could help us. We found Eric. Eric was incredible. Not only did he arrange us to be picked up, he immediately ordered the parts based on my description of what I hear and see under the hood. As soon the car was towed in, he found and replaced the broken pulley and the belt was running again, installed it in our car within record time. While he was working on the car, his wife offered us snacks as courtesy. We were so grateful for him because otherwise we would have been stranded. When he showed the bill I was surprised as I was expecting a heavy bill. Eric at A-One performance auto is very reasonable. If you are exploring auto shops in the area, don’t think twice and just come to A One. This family owned business was incredibly hospitable and kept our nerves calm the entire time. We genuinely thought we would be stuck there for the weekend and they truly are god send and saved us. We cannot thank them enough and are grateful that people like Eric and his wife exist, with the kindness and thoughtfulness they carry. Fully restored my faith in humanity. Sincerely thank you.”
“I can’t say enough good things about Eric at A1 Auto in Brunswick, Georgia. I was driving back home from Florida to New Jersey when I ended up stranded in Georgia overnight because my car needed repairs. I was in a difficult situation and didn’t know where to turn. I met Eric, and he went above and beyond to help me get home. He was honest, professional, kind, and genuinely cared about helping me—not just making a sale or making money. What impressed me the most was that he helped me out and didn’t charge me anything. It’s not often you meet someone willing to help a complete stranger simply because it’s the right thing to do. Eric is a great guy, and I’m extremely grateful for what he did for me that day. If you’re anywhere near Brunswick and need someone you can trust, I highly recommend A1 Auto and Eric. Five stars without hesitation! Thank you again, Eric, for helping me when I really needed it. I’ll never forget your kindness.”
“My husband and I are on the road heading to NC and our AC was pretty weak and knew it has to be the cabin filter or something. Ive called several places and they’re closed but this place; they’re a lifesaver! The guy came by quickly and took a look and sure enough, it was the cabin filter and told us we’re good. Now our air is blowing much better and we can actually go to NC to celebrate my mom’s 60th birthday. Even though we’re not from here but I definitely highly recommend them for any car issues!”
“We were on our way home to Florida and our check engine light came on. They took us right in, ran a diagnostic check, road tested it thoroughly, and let us know that it was probably the fuel sensor detecting a partial amount of bad gas and that it was fine to drive home. Did not want a penny, but I insisted on paying them a small labor charge. When we left, the check engine light was off! Thank you A-One Performance Auto for your kindness and honesty! If you are in Brunswick and need auto repairs, I highly recommend them!😊😊”
