The following advertising campaigns were localized using poor machine translation, which led to disastrous (and often humorous) results.

1. English to Spanish: KFC’s Finger-Licking Fail

When KFC expanded to China in the 1980s, its famous slogan, “Finger-Lickin’ Good,” was translated into “Eat Your Fingers Off” (吃掉你的手指) due to poor machine translation. But did you know that Spanish-speaking markets have faced similar mistranslations?

A major U.S. fast-food chain once relied on AI-generated translation for a Latin American marketing campaign. The phrase “Grill with Confidence” was translated into “Asa con confianza.” While grammatically correct, the phrase lacked the natural, engaging tone needed for marketing. Worse, in some Latin American countries, “Asa” (imperative of “asar,” meaning to grill) could sound like a command rather than an encouragement. Native Spanish speakers would likely phrase it as “Disfruta de la parrilla con confianza” to better match the brand’s intended tone.

2. English to German: Mercedes-Benz’s “Bite the Dust” Slogan

Mercedes-Benz once faced a branding nightmare when entering the Chinese market with “Bensi” (奔死), which sounded like “Rush to Death.” But German brands have also faced linguistic mishaps when relying on direct machine translation.

A German car manufacturer once ran an ad campaign with the English slogan “Experience the Drive.” AI-generated translation rendered it as “Erleben Sie die Fahrt,” which, while technically correct, sounded robotic and uninspiring. A human translator would have opted for something more natural, such as “Freude am Fahren erleben” (Experience the Joy of Driving). 

3. English to French: Pepsi’s Promise of Resurrection

Pepsi’s infamous slogan “Come Alive with Pepsi” was disastrously translated into Chinese as “Pepsi brings your ancestors back from the dead.” But did you know that French translations can also suffer from unnatural AI-generated results?

A tech company promoting “seamless integration” of its software used AI translation for a French campaign. The result? “Intégration sans couture,” which literally means “Integration without sewing” — a phrase that makes no sense in French. The correct phrase should have been “Intégration fluide” or “Intégration harmonieuse.”

4. English to Japanese: Powerade’s Misstep

Coca-Cola’s Powerade once ran an ad campaign emphasizing “Power Water.” When translated into Japanese using AI-generated translation, it became “Chikara Mizu” (力水), which could be interpreted as “Forceful Water” or even “Violent Water” — hardly the message a sports drink brand wants to convey. A more appropriate term would have been “エナジーウォーター” (Energy Water).

5. English to Arabic: Ford’s Unfortunate Promise

Ford once ran an English campaign with the slogan “Every Car Has a High-Quality Body.” When translated into Arabic using AI-generated translation, it came out as “كل سيارة لها جثة عالية الجودة” — which unfortunately means “Every car has a high-quality corpse.” Arabic is a highly context-dependent language where direct AI-generated translations often fail. Had this been translated by a human, the word “هيكل” (structure/body of a car) would likely have been used instead of “جثة” (human corpse).
