Toyota (NYSE:TM) announced that it is suspending production at all 28 lines of its 14 plants in Japan beginning on Tuesday due to what the Japanese automaker called a "system malfunction."
A key domestic supplier suspect the Toyota issue may be a cyberattack because its own system could not communicate properly with Toyota or monitor production. There are separate reports of issues with other suppliers.
It is unclear when the Toyota problem will be fixed and the timeline for production to resume.
Toyota (TM) and other automakers are already struggling with shortages of computer chips and other parts due to disruptions from the coronavirus pandemic.
