2011 Lexus GS 460 Check Engine Light Codes

At Park Place Lexus Grapevine in Grapevine, TX we regularly diagnose several common trouble codes on the 2011 Lexus GS 460. Typical codes include P0300 (random/multiple cylinder misfire) which can start as a simple spark-ignition issue but, if ignored, leads to poor fuel economy, rough running and catalytic converter damage—repair costs can rise from modest spark plug or ignition coil replacement (roughly $150–$600) to catalytic converter replacement well over $1,000. P0420 (catalyst efficiency) often begins with worn oxygen sensors ($200–$500) but unchecked will escalate to converter work. P0455 (EVAP large leak) can be a cheap gas cap fix or a higher-cost EVAP component repair ($200–$600) if left alone. Codes such as P0171 (system too lean) and P0128 (thermostat) signal fuel or cooling issues that may cause overheating or increased engine wear over time. Our certified Lexus technicians use OEM-grade scanners and diagnostic processes to pinpoint root causes, present clear repair options, and explain immediate and long-term costs so you can make an informed decision. Protecting your 2011 Lexus GS 460’s performance and resale value is our priority—review current service specials or schedule service to start with a precise, warranty-friendly inspection.
