Check Engine Light Flashing

The check engine light flashing in a 2016 Lexus LX 570 is an urgent indicator of a severe misfire or condition that can damage the catalytic converter and other critical components. A flashing light typically means the engine is misfiring repeatedly, which can overheat and destroy emissions hardware while reducing power and drivability. At Park Place Lexus in Plano, TX, our certified technicians prioritize flashing-light diagnoses and will isolate ignition, fuel, or sensor causes using factory-level scan tools. Immediate inspection minimizes long-term repair bills and protects vehicle lifespan. We provide a transparent estimate, explain warranty implications, and recommend OEM parts to restore performance. If you notice a flashing light, do not delay — reduce load on the engine and contact us to schedule service.

Our goal is fast, reliable repairs with clear communication and lasting value.

2016 Lexus LX 570 Check Engine Light Reset

At Park Place Lexus, we recommend a complete scan and repair before resetting so you preserve vehicle health and warranty coverage. Our technicians use OEM procedures to read codes, verify freeze-frame data, and test related systems; we only reset codes after confirming the fault is repaired. This approach prevents repeat visits and delivers long-term savings, often costing less than independent shops when factoring accuracy and warranty protection. We provide clear estimates, OEM parts, and post-repair verification. For convenience, you can schedule service online, review current service specials, and enroll in service financing if needed.
