Adams v. Toyota Motor Corp.

Koua Fong Lee (plaintiff) was exiting a freeway in his 1996 Camry when the brakes failed to stop the car, causing an accident that killed three people. Lee was convicted of vehicular homicide and later released after Toyota recalled several Camry models for unintended acceleration. Lee and relatives of the deceased (Adams) (plaintiff) sued Toyota (defendant), alleging a defective acceleration system caused the accident, and sought to introduce evidence of other similar incidents (OSIs).

Whether evidence of other similar incidents is admissible only if those incidents occurred under circumstances substantially similar to the incident at issue in the case at trial.
