Toyota Unintended Acceleration Crisis
Estimated impact: $1.2B DOJ settlement; $3B+ total costs; 89 deaths alleged
Toyota recalled 9 million vehicles for unintended acceleration linked to floor mat entrapment and sticky throttle pedals. The company initially blamed drivers, then floor mats, before acknowledging mechanical defects. Congressional investigation revealed Toyota had suppressed internal safety data.
Decision context
Whether to investigate and disclose unintended acceleration complaints transparently or attribute them to driver error, and whether to issue proactive recalls before regulatory pressure.
Decision anatomy
Red = risk factor present · Green = protective factor present
The analysis below was produced from the pre-decision document only. No hindsight. This is what the platform would have surfaced if it had been running in 2009-10.
“NHTSA received over 2,000 unintended-acceleration complaints on Toyota vehicles between 2000-2009. Toyota's internal response in 2007-2009 was consistent: attribute to floor-mat entrapment, then to pedal geometry, then (after initial recalls) to driver error. House Energy and Commerce Committee testimony and subpoenaed internal documents revealed that Toyota's Washington office had celebrated 'saving $100M by limiting scope of 2007 recall' in a presentation to Tokyo executives. DOJ's 2014 Deferred Prosecution Agreement charged Toyota with wire fraud specifically for misleading federal investigators about known defects.”

Red flags detectable at decision time
- 2,000+ unintended acceleration complaints over a decade attributed to driver error
- Internal Toyota presentation celebrated 'limiting scope' of 2007 recall to save $100M
- Pattern of escalating explanations (floor mat → pedal geometry → driver error) suggests motivated reasoning
- Toyota engineering culture resisted external feedback about defect reports
- Communications to NHTSA contained misrepresentations later charged as wire fraud
Cognitive biases the platform would have flagged
Hypothetical analysis
DI would flag the Toyota unintended-acceleration case as the canonical selective-perception + loss-aversion failure. Each successive explanation (floor mat → pedal → driver) was chosen because it minimized recall scope and cost — the decision question was never 'what is causing this' but 'what causes can we plausibly attribute it to that minimize our liability.' The $100M 'savings' presentation is the decision-intelligence smoking gun: an internal document explicitly framing limited-recall decisions in cost-savings terms rather than customer-safety terms.

Lessons learned
- Selective perception: Toyota filtered customer complaints through the assumption that drivers were at fault, dismissing systemic signals
- Status quo bias in Toyota's "we know best" engineering culture resisted external feedback about product defects
- The $1.2B DOJ fine was for misleading investigators, not the defect itself — the cover-up cost more than transparency would have
