This bulletin provides information related to the engine control module software update for the electronic control unit in certain 2012-2014 Kia Sorento, 2012-2013 Optima and 2012-2013 Sportage vehicles equipped with the 2.4L and 2.0L Turbo GDI engines.

This bulletin provides information related to the engine control module software update for the electronic control unit in certain 2012-2014 Kia Sorento, 2012-2013 Optima and 2012-2013 Sportage vehicles equipped with the 2.4L and 2.0L Turbo GDI engines.

The engines are equipped with a gasoline direct injection system that utilizes a flow control valve (FCV) to control the supply of fuel. The FCV needle may experience excessive wear, eventually resulting in impairment of fuel flow. If this happens, and to protect the engine, the ECU may reduce engine acceleration while illuminating the check engine light. The ECU update will improve the durability and operation of the FCV needle.

To correct the condition, the ECU should be reprogrammed using the currently available GDS download.
