This bulletin provides information related to a Electronic Stability Control (ESC) software upgrade available for some 2011 MY Sorento (XM) vehicles with manual transmission built from October 23, 2009 to March 30, 2010. This software upgrade will correct a concern which may cause the HAC (Hill-start Assist Control) to not operate when the manual transmission lever is placed into Reverse.
Kia recommends that vehicles with this concern receive this software upgrade to allow the ABS HECU to properly apply the HAC function when the vehicle is in Reverse.
