USMC Veteran & Family Owned
Huddleston's Garage is a USMC veteran and family-owned shop serving Avon and the surrounding Indianapolis area. We built this shop on the same standard we held to in the service: do the job right, tell people the truth, and don't cut corners because no one's watching.
How We Diagnose Your Vehicle
Before we recommend a repair, we diagnose. That means pulling codes, testing the actual components involved — not just clearing the code and hoping it doesn't come back — and confirming the cause before any parts get ordered. For engine and transmission concerns, that can include compression and pressure testing, live data review, and road testing to reproduce the issue. For electrical or no-start complaints, it means tracing circuits and testing components individually rather than guessing.
On diesel trucks of every make, that same process extends to fuel system pressure testing, turbo boost diagnostics, and emissions system checks. Read more on our diesel repair page.
Most repairs are backed by a workmanship warranty — ask us for the specifics on your repair when you schedule.
