No one has added these features to there Hyundai Sonata Hybrid (HSH) that I know of so why don't you be the first to try it. They are available on the Genesis so the parts might be able to be added to the Sonata.
Both options are available in KDM vehicles, and both are being added to the '14 Sonata. I have seen some retrofit kits, but they all look like aftermarket add-ons, and I haven't determined a "clean" way to install either. If you go for it, let us know how it goes!
