Why is CO still ordering seats from Koito??

Forget the fact they are less comfortable than sitting on a wooden bench in the park, but a simple web search shows they have a long-standing culture of falsification, safety violations and deceit - and this pre-dates the safety escapade that got the Japanese government involved.

Also, I don't believe Koito manufactured the throttle systems for Toyota - but Toyota does have an ownership stake in Koito Manufacturing and they are part of their exclusive supplier system (keiretsu).

Sounds like the perfect opportunity to source a new seat supplier and design...sometimes you need to bite the bullet and move on.
