In 2008 Chrysler filed for bankruptcy. That is the only car company I know of that filed, and it didn't go bankrupt, it was bailed out by the government, saving tens of thousands of jobs. Since then, the American auto companies have done very well and are all making a profit; Chrysler repaid the government at a substantial profit, so the taxpayers actually made money on that deal. . So I'm not sure what car companies you are talking about, maybe some in other countries?
