What the ministry says is wrong

EVのバッテリ管理システムにおいて、生産管理が不適切なため、異なる制御プログラムが搭載されているものがある。そのため、当該システムが起動する際に内部システム間の通信障害が発生し、最悪の場合、バッテリ警告灯の表示とともに、モータ電源が供給されず車両が動かなくなるおそれがある。

What is to be done about it

全車両、バッテリ管理システムの作動点検を行い、正しく作動しない場合はEVバッテリを良品に交換する。

The two passages above are quoted in Japanese because that is the language the ministry published them in. This site keeps the wording a register had when it was read, and does not translate a safety notice.

This site gathered the record, grouped it by notification number and set it in English around the ministry's own words; the notice itself is unaltered.
