According to a Toyota spokesman, the system disruption made ordering parts impossible and affected about 28 assembly lines that make models ranging from the most popular Corolla and Camry to Prius hybrids. The company does not believe the system malfunction was caused by a cyber attack, a Toyota spokesman said.
On Tuesday, 12 out of 14 Toyota plants in Japan were closed during the day shift. The only exceptions were the Toyota plant in Miyata (Fukuoka Prefecture) and the companies of its subsidiary Daihatsu Motor Co. in Kyoto. Hino Motors Ltd., another Toyota subsidiary, also announced problems with the computer system on Tuesday that caused four assembly lines at two plants in Japan to shut down.
Recall that in March 2022, Toyota shut down all of its 14 plants in Japan due to a ransomware cyberattack on its supplier Kojima Industries. At that time, it took several days for the company’s operations to recover, and the losses caused by the incident amounted to about 5% of the monthly production volume.
