2022 Lexus RC 350 Check Engine Light Reset

Resetting the check engine light on a 2022 Lexus RC 350 can be tempting as a quick fix, but a reset without diagnosis risks masking an underlying fault. At Park Place Lexus in Plano, TX, our approach prioritizes long-term vehicle health: we read and record diagnostic trouble codes with OEM-grade scanners, determine the root cause, and then clear codes only after the issue is resolved. That transparency prevents repeat failures and conserves resale value. When you choose dealer service, you get factory-trained technicians who follow Lexus procedures, genuine OEM parts, and a documented repair history that supports warranty claims. If a code is caused by a covered component, the repair must be performed at a certified dealership to maintain warranty validity — we’ll check that for you. We also help with cost planning and offer service financing so you can address necessary repairs now and spread payments later.
