Daihatsu, a Japanese car maker, has suspended all its domestic production due to a safety testing scandal. The Toyota-owned company has closed all four of its domestic plants, affecting about 9,000 factory workers. Production will be suspended through January and the company is uncertain when it can resume. This move could impact over 8,000 companies across Japan. Daihatsu admitted to manipulating safety tests since 1989, affecting 64 models, including some sold under the Toyota brand. In addition to suspending production in Japan, the company also halted production of two hybrid vehicle models due to similar irregularities. Founded in 1907, Daihatsu was taken over by Toyota in 1967.
