The car seems pretty nice. Unfortunately, "nice" probably will not cut it. The competition from affordable sedans like Camrys, Mazda 6s, Maximas, and Accords, as well as the very solid Kia/Hyundai offerings, will be hard to overcome with people shopping in this category. For people interested in more upscale cars, this doesn't have the allure of something like a Genesis G70 to lure people away from Audi or Lexus, either.
I'm just not sure what niche this actually fills. It seems like a solution in search of a problem.
