Yoon Auto is a general automotive repair shop on Mowery Street in Indianapolis. Founded in 2018 by Byung J Yoon, we handle everything from routine oil changes and brake jobs to check-engine-light diagnostics. We work on most makes and models — domestic and foreign, cars, trucks, and SUVs. Our approach is simple: diagnose the problem accurately, explain what needs to be done, and get it fixed right the first time. No upselling, no unnecessary work. Whether you need a quick oil change or a full engine diagnostic, we treat every vehicle like it's our own. We use quality parts and stand behind our work.
