KIA Motors review: steering column flexible coupler replacement

the streering coupler problem is NOT park under warranty?i need to pay up to RM 500 to replace it at Serdang Service Centre ( Az SC )...
I think that i failure must be park under warranty...

my car is k5 optima 2013 and need to replace it.the SC saying that price is due to the high hand skill needed to replace/open the box to replace it.

pls help to verify...if not your SC is making money easily...
