2017 Hyundai Santa Fe Sport Check Engine Light Reset

Resetting the check engine light on a 2017 Hyundai Santa Fe Sport can be done electronically, but the correct course is diagnosing and repairing the root cause before clearing codes. At Nalley Hyundai in Georgia our service team uses factory-grade diagnostic tools and OEM software to identify active and pending trouble codes, confirming whether a simple sensor reset, updated software or a component replacement is required. Clearing the light without repair can mask faults, lead to failed emissions checks, and void warranty coverage.

Choosing Nalley Hyundai delivers immediate savings through accurate diagnostics and long-term savings by preventing repeat repairs.
