Toyota did not have a good Wednesday. The carmaker first halted all worldwide shipments from Daihatsu, one of its subsidiaries, over an investigation related to safety. The company also had to recall 1 million vehicles in the U.S. due to problems with its cars' airbags.

Daihatsu admitted in April that it rigged side-collision safety tests for vehicles mostly sent to Toyota. That revelation led to an independent third-party investigation, which uncovered 174 safety irregularities in 64 models, including those delivered to Toyota, Mazda and Subaru. On Wednesday, Daihatsu halted sales of all Dahaitsu-developed models currently in production, both in Japan and globally.
