While there, at one time, was a "Hyundai Genesis" there hasn't been for some time. "Genesis" is now the luxury brand of "Hyundai".

You wouldn't say... "Would you not buy a Toyota Lexus because of the name?"

Hyundai spun the name off as a brand in 2015 [0].

Technically, you're right - because there is a car by that name (albeit old now). But, for future reference!
