I think they initially thought it was the floor mat jamming the gas pedal down, but now I dont think they know exactly what causes it.

It all boils down to Toyota relying on another company to make their pedals (CTS based in Indiana) instead of building it themselves or from a parent company like they normally do.

Heres a press release from Toyota. Notice no Japanese built truck are affected since they use Japanese built Toyota gas pedals.
