#Supply

We finally know who’s responsible for shutting down Nissan assembly lines in Japan and the U.S.A. The shortage of a critical computer chip stopped Hitachi from making ECUs, which in turn stopped Nissan from making cars. For days, the identity of the lackadaisical chipmaker had been kept under wraps. Now, the culprit has been unmasked.

The shortage of a critical computer chip that Hitachi desperately needs to supply Nissan with ECUs now threatens to affect U.S. production. Yesterday, Nissan warned that they will close down Japanese assembly lines. Today, Nissan COO Officer Toshiyuki Shiga said that production in the U.S. may be halted until the chip shortage is solved.

So far, it had been striking workers at Chinese parts suppliers that brought Japanese car makers to their knees, praying for parts needed to re-start the lines. Here is a new twist: Japan’s Hitachi ran out of chips for ECUs (commonly called “car computers”). And Japanese carmakers are shutting down the lines.
