Toyota Japan has recovered from a self-described "production order system failure" that caused all 28 production lines at 14 factories in Japan to stop production starting Monday night.
Toyota is famous for and proud of its lean, just-in-time and extremely stable Toyota Production System. This system means Toyota has very low component inventories because they are not available until almost the moment they need to be installed into the vehicle.
However, when a problem occurred in the production order system, the system stopped working.
Toyota isn't sure what happened.
"We do not believe the system failure was caused by a cyberattack. However, we will continue to investigate," Toyota said in a statement released on Tuesday.
Japanese media reported that production resumed as scheduled on Wednesday. Some reports suggested that the glitch was caused by ongoing work on production systems, suggesting that some problematic code may have made its way into production.
Regardless of the cause of the problem, it is self-evidently embarrassing for Toyota, which has suffered multiple data breaches recently. Who can forget when it left customer information on a public GitHub page for five years? Or is it 20 years of false emissions data?
Indeed, that's what it feels like.
Toyota sought to reassure buyers and investors by claiming the incident did not affect production, suggesting something went wrong in some system and was the cause of the shutdown.
However, this has not always been the case, especially with the impact of the COVID-19 pandemic on global supply chains and semiconductor shortages in recent years.
At least, the incident was not a problem that caused the car to lose its tires. At the beginning of this year, both Toyota and Subaru recalled some models for this reason.
