What the ministry says is wrong
ショベル・ローダの静油圧変速機のＨＳＴ バルブの制御プログラムにおいて、設計検討が不?分なため、指令よりも低い圧?で油圧が開放し、?速に応じた変速制御ができなくなることがある。 そのため、変速に失敗して加速した場合、ＨＳＴ モータポンプの回転数計測センサが異常を感知してエラーを発報し、変速段がニュートラルとなり、?両が停止するおそれがある。What is to be done about it
全?両、トランスミッションコントローラとモニターコントローラを対策プログラムに書き換える。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.

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 Komatsu: 297 in the register, and 380 Japanese vehicle recall notifications filed in 2025.
