Diesel is in our name
Diesel specialists, not dabblers

Local know-how
Auto & diesel repair in Athens & Northeast Georgia
Appalachian Auto & Diesel is a full-service repair shop on Danielsville Road in Athens, Georgia, serving drivers across Clarke, Madison, Jackson, Oconee, and the surrounding Northeast Georgia counties. We work on cars, trucks, SUVs, diesel pickups, commercial and fleet vehicles, motorcycles, ATVs, and side-by-sides — just about anything with an engine and a problem to solve.
What sets us apart is how we diagnose. A lot of shops read a code and start replacing parts. We take an engineering-based approach: we find the root cause first, then fix it, so you're not paying twice for the same problem. It's a slower way to start a job and a much faster way to actually finish one.
Diesel done right
Diesel is half our name for a reason. We have deep experience with the Duramax, Cummins, and Power Stroke platforms and the GM trucks many of them ride on. As an authorized FASS Fuel Systems and BD Diesel Performance dealer, we don't just repair diesels — we protect and improve them with proven fuel systems, towing upgrades, and reliability hardware, all installed correctly and legally.
Keeping you on the road
Whether you've got a check-engine light you can't ignore, a work truck that can't afford downtime, or a diesel you want to last 300,000 miles, we're here to keep you moving. Hours vary, so it's best to call or text to schedule — and drop-off is always available on request.
