2017 Lexus RX 350 Check Engine Light Codes

The most common check engine light codes for a 2017 Lexus RX 350 identified at Stevinson Lexus of Frederick include P0420 (catalyst system efficiency), P0171/P0174 (lean condition), P0300–P0306 (misfires), and P0135/P0136 (oxygen sensor/heater circuit). Ignoring these codes can escalate repair costs and reduce safety: a faulty catalytic converter (P0420) can lead to engine performance loss and emissions failure, often costing several hundred to over a thousand dollars if left until complete failure. Lean conditions may increase fuel use, harm the catalytic converter, and produce driveability problems. Misfires accelerate engine wear and risk costly damage. Our dealer-grade diagnostics isolate the exact cause so you pay only for necessary repairs. Stevinson Lexus of Frederick provides certified Lexus technicians, OEM parts, and transparent estimates to protect resale value and minimize long-term expenses.

At Stevinson Lexus of Frederick our first step is a rapid, dealer-grade scan to identify the failing component and recommend OEM replacement parts if needed. We emphasize customer convenience — same-day diagnostics where possible, transparent estimates, and service financing options to help you address urgent repairs without delay.

2017 Lexus RX 350 Check Engine Light Reset

Resetting the check engine light on a 2017 Lexus RX 350 can be done with a diagnostic tool, but a reset without repair only hides the symptom — it doesn’t fix the root cause. At Stevinson Lexus of Frederick we recommend a full diagnostic first: our technicians retrieve the exact trouble codes, interpret whether codes indicate transient or persistent faults, and advise on the appropriate OEM repairs. Resetting at the dealership is part of a controlled, transparent process that preserves warranty coverage and vehicle history. We use genuine Lexus parts, provide written estimates, and explain how timely repairs save money over time by avoiding component cascading failures. Take advantage of our service financing options and current service specials. To ensure a proper, lasting repair rather than a temporary reset, schedule service with our certified technicians today.
