2025 Hyundai Kona Check Engine Light Flashing

A flashing check engine light typically signals an active engine misfire that can damage the catalytic converter if the vehicle is driven. Flashing is more urgent than a steady light and requires immediate attention: continued driving may cause overheating, increased emissions, and costly exhaust system failures. At Courtesy Hyundai of Tampa our technicians prioritize flashing-light inspections, using factory diagnostic tools to identify misfires, ignition faults, or fuel delivery issues. Prompt repair limits damage to expensive components and preserves long-term fuel economy and reliability. For concerns covered by warranty, having repairs performed at our certified dealership ensures coverage remains valid and often delivers lower total cost of ownership than piecemeal independent fixes.

2025 Hyundai Kona Check Engine Light Reset

Resetting the check engine light can be done with an OBD-II scanner or by disconnecting the battery, but clearing a code without repairing the underlying issue only masks symptoms and risks emissions failures or further damage. Our dealership resets codes only after a complete diagnosis and confirmed repair, ensuring the condition won’t recur. Factory-trained technicians verify related systems, perform road tests, and reset monitors correctly so your Kona reports accurate status for inspections. Repairs covered under warranty must be completed at a certified dealership to protect coverage. Choosing Courtesy Hyundai of Tampa delivers immediate diagnostic accuracy and long-term savings by avoiding repeat visits and premature component replacement.

2025 Hyundai Kona Check Engine Light Codes

Common codes for the 2025 Hyundai Kona include P0420 (catalyst efficiency), P0300 (random/multiple misfires), P0171/P0174 (lean condition), and P0456 (small EVAP leak). Ignoring these codes can lead to reduced fuel economy, failed emissions testing, and expensive component failure — a damaged catalytic converter can cost well over $1,000 to replace. Early diagnosis typically costs far less and prevents cascading damage. At Courtesy Hyundai of Tampa we provide clear cost estimates for recommended repairs and highlight immediate and long-term savings. Warranty-covered repairs must be completed at a certified dealership to maintain coverage and ensure genuine parts and proper calibration.
