McDonald's pulls IBM drive-thru AI after customers receive $250+ of unwanted McNuggets
McDonald's AI-powered drive-thru ordering system, developed in a joint venture with IBM, failed repeatedly across more than 100 test locations, generating incorrect and excessive orders that enraged customers. In documented incidents, the voice AI misinterpreted customer requests and autonomously added large quantities of items never requested, including over $250 worth of chicken McNuggets and unwanted packs of butter charged to individual customers. Rather than escalating ambiguous or unlikely orders to a human worker, the system processed them as-is. Customers filmed their interactions and posted the footage to social media, turning the failures into a public relations liability. Faced with sustained evidence that the technology could not reliably replace human order-takers, McDonald's announced it was terminating the IBM partnership and removing the AI system from all test restaurants. McDonald's USA chief restaurant officer Mason Smoot acknowledged the discontinuation in a statement but indicated the chain would continue exploring voice ordering solutions more broadly. The rollback ended a pilot that had expanded to over 100 locations.
