2025 Hyundai Tucson Check Engine Light Reset

Resetting the check engine light on a 2025 Hyundai Tucson can be done by clearing codes with an OBD-II scanner, disconnecting the battery briefly, or after resolving the underlying fault. However, simply resetting the light without diagnosing and repairing the cause risks masking issues that can damage your Tucson over time. At Courtesy Hyundai of Tampa, our factory-trained technicians not only reset the light but perform a full diagnostic to address root causes—this protects your vehicle, preserves warranty eligibility, and delivers immediate and long-term savings. Repairs covered under warranty must be completed at a certified dealership; choosing us keeps your coverage intact and ensures OEM parts and proper procedures are used.

2025 Hyundai Tucson Check Engine Light Flashing

A flashing check engine light in a 2025 Hyundai Tucson typically signals a serious problem, most often an active engine misfire that can quickly damage the catalytic converter and other components. When the light flashes, reduce speed, avoid heavy loads, and have the vehicle inspected immediately to prevent catastrophic engine or emissions system damage. Our dealership offers urgent diagnostics, towing coordination, and same-day attention when possible—this rapid response often limits repair scope and cost. Because warranty-covered repairs must be handled at certified dealerships, bringing your Tucson to Courtesy Hyundai of Tampa protects factory warranty benefits and ensures repairs are completed by technicians trained for Hyundai systems.

Common codes for a 2025 Hyundai Tucson include P0300–P0304 for misfires, P0135–P0167 for oxygen sensor issues, P0420 for catalytic converter efficiency, and P0171 for a lean condition. Ignoring these codes can lead to increased fuel consumption, poor performance, failed emissions tests, and costly component failures—catalytic converter replacement can run into the thousands. Prompt diagnosis at our dealership helps avoid these outcomes and reduces long-term expenses. We provide transparent cost estimates, OEM parts, and factory-calibrated repairs. Warranty-covered issues must be repaired at a certified dealership; using our service ensures coverage stays valid and you benefit from immediate and lasting savings.
