TOKYO - Japanese automaker Daihatsu Motor suspended all domestic production on Tuesday amid a scandal over its safety test falsification.

The carmaker on Tuesday halted operations at its factory in Osaka prefecture after shutting down three other plants in Shiga, Kyoto and Oita prefectures the previous day, bringing domestic production to a complete halt.

Daihatsu announced last week that an investigation found 174 new cases of misconduct regarding the safety testing of new vehicles involving 64 models

The four factories are expected to remain suspended at least until the end of January next year, Daihatsu said Monday, promising to compensate all the companies it directly supplies.
