Check Engine Light Flashing

The sight of a flashing check engine light on your 2011 Lexus RX 350 indicates a severe or misfire condition that may harm the engine or catalytic converter if driven without immediate attention. Flashing typically signals intermittent misfires, which raise exhaust temperatures and can lead to costly catalytic converter damage; it can also point to ignition or fuel delivery faults. At Park Place Lexus Grapevine in Grapevine, TX, our certified Lexus technicians are trained to diagnose flashing-light emergencies quickly—stopping potential damage and minimizing repair costs. We start with a thorough scan of engine codes, perform compression and ignition checks, and inspect fuel and charging systems, including battery and alternator testing. If a battery replacement is required, we use OEM-grade batteries matched to the RX 350’s specifications and provide professional installation and disposal. Ask about our current service specials and service financing options so you can address urgent repairs now and pay over time.

2011 Lexus RX 350 Check Engine Light Reset

Our dealer advantage includes transparency—detailed repair estimates, OEM parts, factory-trained technicians, and warranty protection; note that any repairs covered under warranty must be performed at a certified dealership to remain valid.

2011 Lexus RX 350 Check Engine Light Codes

Common check engine light codes for the 2011 Lexus RX 350 include P0420 (catalyst system efficiency below threshold), P0171/P0174 (fuel trim/system lean), P0300-P0306 (misfires), and P0130-P0167 series (oxygen sensor or heater circuit faults). Each code carries potential costs if left unaddressed: unresolved P0420 issues can accelerate catalytic converter failure and lead to a large replacement bill; persistent misfires can damage pistons and the converter; fuel system lean conditions reduce fuel economy and risk engine wear.
