2025 Acura RDX Check Engine Light Reset

Resetting the check engine light on a 2025 Acura RDX can be accomplished with an OBD-II reader, but a reset alone rarely solves the underlying problem. A cleared code can hide an intermittent fault or mask a developing issue that later causes more serious damage. At Park Place Acura in Plano, TX our technicians diagnose and repair the root cause before clearing codes, ensuring the repair is permanent. We use genuine Acura parts and factory procedures so repairs meet OEM specifications and maintain warranty integrity; remember that warranty-covered repairs must be completed at a certified dealership. Our transparent process includes a clear estimate, a written explanation of the failed components, and an explanation of immediate and long-term savings achieved by correct repairs. If a battery or charging problem is the cause, we offer OEM battery replacements and prioritized service to avoid repeat codes. To arrange a professional reset and repair with full documentation, please schedule service. Check current service specials for diagnostic and battery offers.

2025 Acura RDX Check Engine Light Codes

Common check engine light codes for the 2025 Acura RDX include P0420 (catalyst efficiency below threshold), P0171 (system too lean), P0300 (random/multiple misfires), and electrical codes such as P0562 (system voltage low). A weak or failing battery can trigger voltage-related codes and intermittent sensor faults. Ignoring these codes can increase fuel usage, degrade driving performance, and lead to expensive repairs—an unchecked misfire can ruin a catalytic converter that may cost well over a thousand dollars to replace. In Plano, Park Place Acura provides precise, OEM-level diagnosis and clear cost estimates so owners understand both immediate repair costs and potential long-term savings from timely intervention. Our certified Acura technicians are trained to interpret codes, test related systems, and recommend repairs using genuine parts to maximize longevity. We also provide service financing to help customers complete recommended repairs without delay.
