There is a Hyundai Technical service bulletin about it. Essentially it says turn on your lights till the heat from the bulbs evaporates the moisture. I have had moisture in my taillight lenses also, and my SC is garaged when home. I have used a hair dryer to slowly heat the lens externally to evaporate the moisture. You have to be careful because the heat from the dryer can negatively impact the lens, but slow application of the heat to the lens works.
