..well yes, 16V is a bit high...do you measure that at the battery or at the alternator?
However, it is not totally unusual for the COLD alternator to be high on voltage...GM alternator regulators commonly do that, then fall back near 14.5 after a few minutes.

ALso....can you verify if the voltage goes up and down with engine RPM....a sign that there may be a real problem with the regulator.
By the way. I changed the original KIA alternator to a GM model....
