Taco Bell AI Drive-Thru Orders Disrupted by Prank and Technical Glitches
Taco Bell's voice AI ordering system at over 500 US drive-throughs experienced glitches and viral incidents including a prank order for 18,000 water cups and repeated prompts to add drinks. The company's chief technology officer acknowledged the technology has had mixed results and is reconsidering its deployment strategy, particularly at busy locations.
What happened
Since 2023, Taco Bell has deployed voice AI ordering at over 500 US drive-through locations. Viral videos showed the system malfunctioning, including one incident where a customer ordered 18,000 water cups and another where the AI repeatedly asked a customer to add more drinks despite him ordering only a large Mountain Dew.
Customers complained on social media about glitches and delays. One Instagram video of the repetitive drink order issue garnered over 21.5 million views.
Reported impact
Despite the viral glitches, Taco Bell reported that two million orders have been successfully processed using the voice AI since its introduction. However, Taco Bell Chief Digital and Technology Officer Dane Mathews acknowledged the technology has had mixed results and sometimes fails to meet expectations.
Index analysis
The incidents reflect challenges in deploying voice AI for real-time customer interaction in high-volume environments. Mathews indicated the company is reconsidering where and how to deploy the technology, acknowledging that busy restaurants with long lines might be better served by human staff rather than AI-only ordering systems.
Governance controls
Taco Bell is rethinking its approach to voice AI deployment across drive-throughs. Mathews stated the company would work with restaurants to determine when to use voice AI and when human staff should monitor or take over orders.
