2013 Lexus IS 350 C Check Engine Light Codes

At Stevinson Lexus of Frederick in CO, we see a pattern of codes on the 2013 Lexus IS 350 C that tell a clear maintenance story: P0300 (random/multiple misfires), P0420 (catalyst efficiency below threshold), P0171/P0174 (lean condition), and P0442 (EVAP small leak). Ignoring these codes increases repair costs and risks — misfires damage pistons and catalytic converters (repairing a converter can cost thousands), a persistent lean condition accelerates engine wear and reduces fuel economy, and EVAP leaks can fail emissions testing and trigger repeat visits. Our certified Lexus technicians use OEM diagnostics and parts to pinpoint root causes and present transparent cost options so you can weigh immediate repair versus monitored service. We streamline the process with comfortable service amenities, honest pricing, and efficiency that often yields lower total ownership cost than repeated independent shop visits. For precise scheduling, schedule service and check current offers on our service specials.
