Jennifer Lopez in an ad for the 2012 Fiat 500c
Chevrolet: "Man Step" ad for the Silverado
This clip was supposed to poke fun at the Ford F-150s "man step", but in the end it just made Chevy look like a bully. And since it called out the F-150 by name, it was free advertising for Ford. This is what we call a lose-lose.
Fiat: "Papi" featuring Jennifer Lopez for the 500
J-Lo is chased by fans. Or zombies. And she might be guilty of a few hit-and-runs. But then she dances her way out of a ticket, and everyone lives happily ever after. Well, except the people that she injured, maybe. If Showgirls were a car commercial, it would look a lot like this.
Hyundai: "Pipe Job" ad for the ix35
This clip was made for U.K. audiences, and it was so controversial, it was immediately taken down. Who'd have thought that poking fun at suicide would be so offensive? (Everyone, that's who.)
Lincoln: "Steer the Script" clip for the MKZ
Letting fans write copy for a Lincoln ad seemed like a great idea. Social engagement! Tech-friendliness! Youth! Unfortunately, the campaign was a complete dud, resulting in this painful, practically unwatchable clip. This is why copywriting remains a noble profession.
Nissan: "G.I. Joe & Barbie" ad for the 300ZX
Ken lost his favorite hooker in a Toy Story knock-off. But hey, he got to keep the beach house, which should've, like, tripled in value. We just hope he sold it before the housing bubble burst.
Honorable mention: the infamous Chevy Volt dance
