McDonald's ended its multi-year AI voice-ordering pilot with IBM after viral drive-thru misorders

McDonald's·An AI-enabled drive-thru voice ordering system built with IBM (based on IBM's Apprente acquisition)

McDonald's had piloted the AI voice-ordering system at over 100 U.S. drive-thrus since 2021; social media users documented it repeatedly misordering, such as adding unwanted items, mixing up orders from adjacent lanes, and ignoring customer corrections. In June 2024 McDonald's confirmed it was ending the IBM pilot.

Blast radius
The pilot was pulled from over 100 U.S. drive-thru locations; McDonald's said it would explore alternative voice-AI vendors rather than abandon automated ordering entirely.
Root cause
Voice-ordering accuracy in the noisy, high-variability drive-thru environment did not reach a level reliable enough for unsupervised production use
How it was caught
Viral social media videos and posts documenting misorders, picked up by trade press
What changed
Partnership with IBM ended; McDonald's said it planned to evaluate other automated order-taking technology

Take-awayA voice agent's error rate needs to be validated against real-world acoustic and workflow variability before wide multi-site rollout, not just controlled pilots
