2025 Acura RDX Check Engine Light Codes

Certain trouble codes commonly appear on a 2025 Acura RDX: P0420 (catalyst efficiency), P0300 (random/multiple misfires), P0171/P0174 (lean condition), and P0135 (oxygen sensor heater circuit). Ignoring each brings rising costs: an unresolved P0420 may lead to catalytic converter replacement, which is expensive; repeated misfires (P0300) can damage pistons and the catalytic converter; lean conditions cause poor performance and increased fuel consumption; and sensor faults lead to failed emissions tests. At Crown Acura Richmond in Richmond, VA, we diagnose these codes quickly using Acura-approved tools, giving a clear cost estimate and repair timeline. Our service center emphasizes customer convenience — loaner vehicles, comfortable waiting areas, and efficient turnaround — plus the peace of mind that comes with OEM parts and certified technicians.
