Is your vehicle included? Check with your VIN at MLIT, or ask a dealer. This page is an independent copy of the notice, kept so you can see what changed after it was published. It is not the authority, and the authority’s own text is the one to act on.

What the ministry says is wrong

ドライバーアシストシステムコントロールユニットにおいて、ソフトウェア開発時の検証が不十分だったため、アクティブレーンキープアシスト機能を使用してコーナリングした際、想定した速度を超過することがある。そのため、最大横加速度が協定規則第７９号の技術的な要件（かじ取装置試験の基準）に適合しない。

What is to be done about it

全車両、ドライバーアシストシステムコントロールユニットのコーディングを正しい仕様に修正する。また、コーディングのバージョンを一致させるため、電子制御パワースステアリングコントロールユニットのコーディングも同時に書き換える。

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.

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. CarsMultiverse is not the ministry and not a safety authority. To act on this notice, use the ministry's own document.

ポルシェ elsewhere in this register

ポルシェ is named on 133 notices in the copy of MLIT’s register held here, of which these are the nearest to this one in time.

The same part: コンピュータ(かじ取

35 notices in this register name コンピュータ(かじ取. A defect that keeps returning under one heading is worth reading as a group rather than one notice at a time.

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 Porsche: 135 in the register, and 371 Japanese vehicle recall notifications filed in 2024.
