2014 Lexus RX 350 Check Engine Light Reset

Resetting the check engine light on a 2014 Lexus RX 350 can be simple or complex depending on the underlying cause. While some owners can clear a pending code after addressing a loose gas cap, the light may return if the root problem persists. At Stevinson Lexus of Frederick we recommend a full diagnostic first so we can reset the system only after confirming proper repair. This approach protects you from repeat trips and hidden expenses: our certified technicians use OEM scanners to verify repairs, clear codes properly, and run drive cycles to confirm resolution. Choosing dealership service means transparency, factory parts, and warranty protection — any repairs covered under warranty must be performed at a certified dealership to maintain coverage. We also offer convenient service financing, accurate written estimates, and periodic maintenance reminders to help prolong engine life. Before you accept a quick reset elsewhere, consider the long-term savings and reliability benefits of letting our team diagnose and repair your 2014 Lexus RX 350.

2014 Lexus RX 350 Check Engine Light Codes

Common codes for a 2014 Lexus RX 350 include P0420 (catalyst system efficiency), P0300–P0306 (random/multiple cylinder misfires), P0171/P0174 (system too lean), and oxygen sensor codes.

At Stevinson Lexus of Frederick our technicians explain each code’s cause, the likely repair path, and an itemized cost estimate so you can weigh immediate versus long-term savings. We emphasize preventive maintenance and genuine OEM parts to extend engine life and minimize total ownership cost.
