Toyota has temporarily halted production at all of its Japanese plants after experiencing a system malfunction, the cause of which is still unknown.
The Japanese carmaker had its first run of issues at the start of this week, resulting in some of its operations being suspended on the first shift of Tuesday. Later that evening, 28 lines in all 14 plants ground to a halt.
Toyota says that the system malfunction was not caused by a cyberattack and that it is still investigating the cause of the issue.
Production at 25 lines in 12 plants resumed as of Wednesday, but lines at its Kyushu Miyata Plant and Daihatsu Kyoto Plant are still down.
Following the glitch, Toyota apologised for any inconvenience it may have caused customers, suppliers, and other related parties.
The affected plants account for nearly a third of Toyota’s global production which is around 13,000 vehicles daily, according to Reuters.
In March 2022, production had to be halted at 14 Toyota plants when a cyberattack affected the carmaker’s ability to order parts.
