Calif: Taco Bell AI drive-through technology has faced notable challenges after a series of viral incidents highlighted system errors. One widely viewed clip shows a customer placing an order for 18,000 cups of water, while another video depicts a user becoming frustrated as the AI repeatedly requested additional drinks.
Since 2023, Taco Bell has implemented AI-driven voice technology at over 500 US locations, aiming to reduce errors and improve service speed. However, the technology has sometimes produced the opposite effect, with mistakes and repeated prompts leading to customer frustration.
Dane Mathews, Chief Digital and Technology Officer at Taco Bell, stated that the company has learned valuable lessons from the rollout. He said that while the AI can be impressive, there are instances when human oversight is more effective, especially during peak hours. Mathews explained that staff are being trained on when to rely on AI and when human intervention is preferable.

Online reactions have amplified awareness of the issue, with millions viewing clips of AI misinterpretations. One Instagram video, viewed over 21.5 million times, shows a man ordering a ‘large Mountain Dew’ as the AI repeatedly asks, ‘and what will you drink with that?’
Taco Bell is not alone in facing AI-related errors. Last year, McDonald’s withdrew AI from its drive-throughs after similar issues, including misinterpreted orders that added unintended items like bacon to ice cream or hundreds of dollars in chicken nuggets.
Despite these viral mishaps, Taco Bell says the AI has successfully processed over two million orders since its introduction. The company has indicated it will carefully evaluate where to deploy AI in the future, potentially avoiding busy drive-through locations to ensure smoother service.
