Check Engine Light Flashing

A flashing check engine light on a 2025 Hyundai Tucson Plug-In Hybrid usually indicates a serious condition such as engine misfire, catalytic converter stress, or an electrical fault that could cause further damage if driven.

2025 Hyundai Tucson Plug-In Hybrid Check Engine Light Reset

Resetting the check engine light on a 2025 Hyundai Tucson Plug-In Hybrid may temporarily clear a stored code, but a reset without repair can mask an ongoing problem and risk warranty coverage or future breakdowns. At Stevinson Hyundai, we perform a proper diagnosis before any reset: identifying underlying causes, performing needed repairs with OEM parts, and then confirming the issue is resolved before clearing codes. This process protects your hybrid battery, emissions systems, and drivetrain while preserving warranty eligibility — warranty repairs must be completed at a certified dealership to remain valid. Our technicians provide an itemized explanation of needed work, timeline, and the immediate and long-term savings of fixing root causes rather than chasing transient symptoms. Review current service specials to save, and schedule appointment online for a fully documented service visit at Stevinson Hyundai.
