Toyota stops operations at 13 plants due to system failure

Toyota Motor has halted operations at its group's 13 plants in Japan due to a system failure, the cause of which is under investigation. The company said it does not believe the issue is related to a cyberattack.

The suspension will be extended to one more facility from Tuesday evening, meaning all of the automaker's domestic factories have been affected.

Company officials said a timeline has not been set for the resumption of operations.

Toyota said a malfunction in the production system has made it impossible to order components. Officials said the company will decide by Tuesday evening how it will proceed in the coming days.

Toyota halted domestic plant operations last year

Toyota was forced to stop operations at all of its domestic plants in March of last year after one of its suppliers was targeted by a cyberattack.

But company officials said that as of now, they do not believe the current issue was caused by a similar attack.
