To be "under X's ownership" means to be controlled or owned by X. In the case of this video, "under Hyundai's ownership" means owned (and likely run/operated) by Hyundai. Ex: The company changed ownership recently, so staff changes will probably take place. Ex: After retiring, the CEO changed ownership of his company to fall under his son.
