I saw a doco and the American prosecution believes the Toyota crash issues are to do with outsourced components. This has been a n issue since they have had very good long term relationships with tier one and tier two parts suppliers but when they expanded to the US they had to outsource parts from companies that they hadn't had a long term relationship with. These parts suppliers could be USA companies. Very easy to point fingers but I think the situation is extremely complicated as these and all cars are made up of parts supplied by numerous companies both US and internationally based.
