Check Engine Light Flashing
The check engine light flashing on a 2025 Lexus IS 300 is a clear sign of an active misfire or a severe combustion issue that can rapidly damage the catalytic converter and other components. If you see a flashing light, reduce speed and limit engine load—avoid highway driving—and bring the vehicle to Park Place Lexus in Plano, TX immediately. Our factory-trained Lexus technicians will perform a prioritized inspection: we scan for codes, inspect ignition coils, spark plugs, fuel delivery, and the charging system, including the battery, which can contribute to electrical faults. Addressing a flashing light quickly preserves long-term performance and avoids costly secondary failures; for example, a neglected misfire can elevate exhaust temperatures and lead to catalytic converter replacement that costs many times more than the initial repair. We offer transparent pricing, OEM parts, and service financing so you can get urgent repairs completed now and pay over time.

2025 Lexus IS 300 Check Engine Light Reset
Resetting the check engine light on a 2025 Lexus IS 300 can be as simple as addressing the root cause and clearing codes with an OBD-II tool, but an immediate reset without repair may mask an active fault and lead to repeated failures. At Park Place Lexus we recommend a complete diagnostic and repair-first approach: our technicians identify and fix the underlying issue—whether sensor replacement, fuel system service, or battery and charging repairs—then perform a controlled reset using factory tools to ensure the code does not return. This approach protects warranties and maintains vehicle health. We use genuine Lexus parts and document repairs so you understand immediate costs and long-term savings. Our service advisors explain warranty coverage and note that warranty repairs must be completed at a certified dealership to remain valid. If you prefer to spread payments, ask about our service financing options. Click to schedule appointment and view current service specials.
2025 Lexus IS 300 Check Engine Light Codes
Common check engine light codes for a 2025 Lexus IS 300 include misfire codes (P0300-P0304), oxygen sensor and catalytic efficiency codes (P0130–P0420), mass airflow and fuel trim codes (P0100–P0171), and evaporative system notices (P0440). Left unresolved, each code carries costs: a simple oxygen sensor repair may be modest, while ignored oxygen sensor faults can damage a catalytic converter—often a thousand dollars or more to replace. Misfires can worsen into engine damage, while fuel system issues decrease fuel economy and increase emissions. At Park Place Lexus in Plano, TX, we provide a clear assessment of likely outcomes and costs, prioritize necessary work to prevent escalation, and offer OEM parts that deliver service life and reliability. Our certified technicians and speedy bays ensure minimal downtime, and our advisors highlight immediate savings through precision diagnostics and long-term value from correct repairs.
