2015 Hyundai Genesis Check Engine Light Codes

Common check engine light codes for a 2015 Hyundai Genesis include P0420 (catalyst system efficiency below threshold), P0171/P0174 (system too lean), P0135/P0136 (oxygen sensor heater circuits), and P0300 (random/multiple cylinder misfire). Left unaddressed, these codes can lead to reduced fuel economy, higher emissions, decreased performance, and potentially expensive component damage. For example, ignoring P0420 can allow catalytic converter damage to progress, turning a sensor repair into a costly converter replacement.
