Check Engine Light Flashing

The check engine light flashing on a 2012 Lexus LFA is a high-priority warning that indicates a severe misfire or condition that may damage the catalytic converter or compromise safety. A flashing light often means unburned fuel is entering the exhaust, which can overheat components and lead to expensive downstream failures. At Park Place Lexus in Plano, TX, our factory-trained technicians use OEM diagnostic tools to identify ignition, fuel delivery, or sensor failures quickly. Immediate inspection minimizes secondary damage and lowers total repair costs — an important long-term saving compared with delaying service. We also test the battery and charging system, since electrical irregularities can mimic or exacerbate engine faults. For convenience, we publish current offers as service specials and provide service financing so you can address critical repairs now and pay over time. Don’t risk further engine or exhaust damage; schedule service online or contact Park Place Lexus to prioritize a rapid, guaranteed repair plan.

2012 Lexus LFA Check Engine Light Codes
