A Hyundai car ad that featured a man trying to commit suicide inside a car caused so much controversy that the South Korean car maker apologized to viewers.

In the ad, a grown adult trying to commit suicide with fumes from one of its SUVs. At the end, he doesn't succed because the car runs on hydrogen and therefore emits 100% water vapor.

"We understand that some people may have found the iX35 video offensive. We are very sorry if we have offended anyone. We have taken the video down and have no intention of using it in any of our advertising or marketing," a company spokesman said in a statement to Forbes.

Hyundai Motor said 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," the company said.

The ad stirred a lot of controversy. An advertising creative whose dad committed suicide in the way portrayed in the ad wrote a long letter on her blog condemning it.

"When your ad started to play, and I saw the beautifully-shot scenes of taped-up car windows with exhaust feeding in, I began to shake. I shook so hard that I had to put down my drink before I spilt it. And then I started to cry," the advertising copywriter wrote on her blog Copybot.
