Somehow Hyundai had no knowledge that this ad was being produced and broadcast on their behalf.
They issued this apology.
Hyundai Motor deeply and sincerely apologises for the offensive viral ad," the company said in a statement.
“The ad was created by an affiliate advertising agency, Innocean Europe, without Hyundai's request or approval. It runs counter to our values as a company and as members of the community. We are very sorry for any offense or distress the video caused.
“More to the point, Hyundai apologises to those who have been personally impacted by tragedy."
Maybe the corporate agency decide to sub out this piece of work to an affiliate without going through the normal checks and balances by Hyundai. Whatever the reason there's a lot of damage control being put into practice at this moment.
