Check Engine Light Flashing

When the check engine light is flashing on your 2025 Acura TLX, it signals a potentially serious condition — often active misfires that can damage the catalytic converter or stress the drivetrain. A flashing light means immediate attention is recommended: continuing to drive can escalate repair costs and risk safety. At Crown Acura Richmond in Richmond, VA, our factory-trained technicians perform a prioritized inspection to pin down causes such as ignition coil failures, fuel injector faults, or sensor malfunctions. We explain the severity, outline required repairs, and present OEM parts and warranty-backed options that preserve vehicle performance and resale value. Take advantage of our comfortable waiting area and efficient workflow; we also offer service financing so you can address urgent repairs now and pay over time.

2025 Acura TLX Check Engine Light Codes

Common OBD-II codes for the 2025 Acura TLX include P0420 (catalyst efficiency), P0300 (random/multiple cylinder misfire), P0171/P0174 (system too lean), and various oxygen sensor or EVAP system codes. Left unresolved, these codes can produce decreased fuel economy, higher emissions, failed state inspections, and in worst cases expensive catalytic converter replacement. Crown Acura Richmond diagnoses each code with OEM-grade scanners and confirms whether a simple sensor replacement, tune-up, or deeper engine repair is needed. Choosing dealership service often costs less than independent shops over time because we prevent repeat visits with correct parts and procedures, and warranty-covered repairs must be done at a certified dealership to remain valid. Our technicians document findings, explain necessary next steps, and provide written estimates so you can make informed decisions.

2025 Acura TLX Check Engine Light Reset

Resetting the check engine light on a 2025 Acura TLX without addressing the root cause is not recommended. A temporary reset may clear the display but will not resolve the underlying fault, risking further damage and wasted expense. At Crown Acura Richmond, we perform a proper diagnostic scan, repair or replace the faulty component with OEM parts, and then clear codes while monitoring readiness monitors to ensure the repair was successful. We provide a full service report and discuss warranty coverage; remember, warranty repairs must be completed at a certified dealership to remain valid. We also offer convenient service financing and ongoing maintenance plans to protect your investment.
