TECHNICAL SERVICE BULLETIN: MULTIFUNCTION SWITCH REPAIR - This bulletin has been revised to include additional information. New/revised sections of this bulletin are indicated by a black bar in the margin area. This bulletin provides information associated with the "Multifunction Switch Warranty Extension Program" (WTY031) to repair the multifunction switch knob on 2016-2018MY Sorento (UMa) vehicles, produced at Kia Georgia from October 27, 2014 through March 7, 2018, which may exhibit an intermittent headlamp flickering. The vehicle's warranty for this issue will be extended from 5 years/60,000 miles to 15 years/150,000 miles, whichever comes first, starting from the date the vehicle was first put into service. The concern does not need to be duplicated in order to follow the procedure outlined in this publication to replace the multifunction switch moving block and outer cover with the new improved part.
