2026 Acura MDX Check Engine Light Codes

In Richmond, VA, Crown Acura Richmond decodes check engine light codes for the 2026 Acura MDX with accuracy and clarity. Common codes include P0420 (catalyst efficiency), P0171/P0174 (lean fuel trim), and P0300 series (misfires). Left unresolved, a P0420 can lead to reduced fuel economy and potential catalytic converter replacement—an expensive repair that often exceeds the upfront cost of a timely diagnostic. Lean codes like P0171 often point to vacuum leaks or fuel delivery concerns that, if ignored, cause uneven performance and higher fuel consumption. Misfire codes risk damaged catalytic converters and drivability loss; early repair protects engine components and preserves resale value. Crown Acura Richmond combines OEM parts, Acura-specific diagnostic software, and certified technicians to identify true root causes and present transparent repair plans. We emphasize immediate and long-term savings—correct fixes reduce repeat visits and extend the MDX’s life. To prioritize your vehicle, schedule service and check current service specials.
