Mitsubishi Heavy Industries (MHI) participated in a ¥540 billion emergency rescue of Mitsubishi Motors in January 2005, in partnership with Mitsubishi Corporation and Mitsubishi Tokyo Financial Group.[18][19] As part of the rescue, MHI acquired ¥50 billion of Mitsubishi Motors stock, increasing its ownership stake to 15 percent and making the automaker an affiliate again. The emergency rescue was carried out 4 years after a product recall scandal in Japan that was triggered by accusations of Mitsubishi Motors allegedly trying to systematically hide manufacturing defects to avoid recalls, and marketing problems in the US.[18]
