Check Engine Light Flashing

The check engine light flashing on a 2016 Lexus RC 300 usually signals a severe engine misfire or a condition that could damage the catalytic converter if you continue driving. In Grapevine, TX, Park Place Lexus Grapevine recommends you stop driving as soon as it is safe and contact our service team — continuing to drive can make a minor repair far more expensive. Our certified Lexus technicians use OEM diagnostic equipment to read transient fault codes and isolate the root cause, whether ignition coils, fuel injectors, or fuel delivery issues. We also inspect related systems such as battery health and charging because weak batteries or poor electrical connections can mimic or compound engine-management problems. You’ll receive a clear, written estimate that shows immediate cost savings by fixing issues before they escalate, and long-term savings through OEM parts and factory training that reduce repeat failures. To get prompt attention, schedule service online and check our service specials to see current offers.

2016 Lexus RC 300 Check Engine Light Codes

At Park Place Lexus Grapevine we frequently diagnose the most common codes on a 2016 Lexus RC 300, such as P0300 (random/multiple cylinder misfires), P0420 (catalyst system efficiency below threshold), P0171/P0174 (system too lean), and oxygen sensor codes. Each of these, if left unaddressed, carries escalating costs: misfires can damage the catalytic converter (thousands to replace), persistent lean conditions reduce fuel economy and engine life, and failed sensors lead to failed emissions tests and reduced performance. Our estimates always outline immediate repair costs and the long-term value of OEM components and factory procedures. Choosing dealer service often means lower overall ownership costs because accurate diagnostics prevent unnecessary parts replacement and extend component life. We also offer battery services and replacements tailored for Lexus systems so electrical faults do not complicate engine diagnostics.
