What the ministry says is wrong

③マイルドハイブリッド車のエンジン制御コンピュータとマイルドハイブリッド用バッテリにおいて、バッテリ制御が不適切なため、バッテリ内部のセルに電圧差が生じることがある。そのため、そのまま使用を続けると電圧差が大きくなり、エンジン始動時に故障判定してエンジン警告灯が点灯し、メータに「ハイブリッドシステム異常」のメッセージが表示され、モータアシストが停止するおそれがある。有車速アイドリングストップ時に故障判定すると、最悪の場合、エンジンが再始動できずエンストするおそれがある。

What is to be done about it

③全車両、エンジン制御コンピュータとマイルドハイブリッド用バッテリの制御プログラムを対策プログラムに修正する。

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.

Reading this against the source

This page is what MLIT published in the recall notices it publishes, kept as it was read. The authority publishes only its current wording; if a notice is rewritten, the earlier version disappears there and is kept here. The whole register is at /japan, and how the reading is done is set out in the method.

This register keeps an index of its own for every maker and every year it holds: Japanese recalls on a Mazda: 471 in the register, and 371 Japanese vehicle recall notifications filed in 2024.
