Toyota, the world’s largest automaker, faced a major production disruption last month when it had to shut down all its 14 factories in Japan due to a system malfunction caused by insufficient disk space. The problem occurred when some servers that process parts orders became unavailable after a maintenance procedure on August 27. The backup function also failed, and the production order system could not operate. Toyota restored the system on August 29 by transferring the data to a larger capacity server.
The shutdown affected about a third of Toyota’s global production and was not caused by a cyberattack, the company said. “We apologize for any inconvenience caused to our customers and suppliers,” Toyota said in a statement. “It was a very rare case, but we have learned a lesson from this incident,” said Masato Sase, a Toyota spokesman.
The incident exposed the vulnerability of Toyota’s production system, which relies on just-in-time delivery of parts from suppliers to minimize inventory and costs. The system is highly efficient, but also susceptible to disruptions from natural disasters, supply chain issues, or human errors.
“It’s surprising that something like this can happen to Toyota, which has a reputation for being meticulous about its operations,” said Takeshi Miyao, an analyst at Carnorama, a market research firm. “Toyota has been trying to streamline its production system and reduce costs, but this incident shows that there is a limit to how much you can cut corners,” he added.
Some analysts said that Toyota should invest more in its information technology infrastructure and security, especially as it faces increasing competition from rivals such as Tesla and Volkswagen, which are more advanced in digitalization and electrification. “This is an embarrassment for Toyota, which is known for its quality control and efficiency,” said Satoru Takada, an analyst at TIW, a Tokyo-based research and consulting firm. “Toyota needs to catch up with the changing times and upgrade its IT systems to prevent such glitches from happening again,” he said.
