In 2016, a special investigation committee reported on improper fuel economy testing at Mitsubishi Motors. It considered that many points were in common with the causes and background of the company’s earlier recall cover-ups. After those cover-ups, the company had taken measures to prevent a repeat. They neither corrected nor prevented the new problem.
The committee wrote that the earlier prevention measures had been of no use at all in preventing the problem or finding it early. Because the case of 2004 had concerned the improper handling of quality information, the company’s awareness of the problem had stayed limited to quality information.
