New as off Jan 2013
Just saw this new TSB for many 6spd at trans models while I was looking up something in the manuals.
2011> Sorento (XMa) 2.4L Theta II & 3.5L Lambda II
TSB 047 [Rev 1, 1/25/2013]
This bulletin provides information regarding axle shaft serviceability for Kia vehicles equipped with a six-speed automatic transmission. Refer to the table below for a detailed list of vehicle models. Individual service parts such as axle boots, joints and hardware for inner joint are now available through your parts department.
There are many other models included but this is the only one that concerns me as I have a 2011 Sorento with V6.
