paint chipping is only an issue on two colors, micro blue and yellow.
Suspension not tuned right cloud be hardly classified as an issue, as most owners do not find a problem with it. It is only those that drive their car hard that have complained.
Rattles and Creaks, the only complaints I have read about is the hatch (which Kia already addressed) and the sunroof which has affected few owners
In my opinion for a first year, first generation and first ever on everything for Kia, I think the Stinger has the least problems when compared to other brands.
