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

車両制御コンピュータにおいて、スマート・ブレーキ・サポートの制御プログラムが不適切なため、道路横に斜めの金属壁などがあった場合に、前進時左右接近物検知機能が誤作動することがある。そのため、衝突の可能性がないにもかかわらず障害物との接近を知らせる警報音が鳴り、ディスプレイに警告表示が出て、最悪の場合、衝突被害軽減ブレーキが作動し、急制動がかかるおそれがある。

What is to be done about it

全車両、車両制御コンピュータ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.

Source: Ministry of Land, Infrastructure, Transport and Tourism website （出典：国土交通省ウェブサイト）, used under the Public Data License 1.0. 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.

The Japanese register on this site

マツダ elsewhere in this register

マツダ is named on 465 notices in the copy of MLIT’s register held here, of which these are the nearest to this one in time.

The same part: 装置その他

210 notices in this register name 装置その他. 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 Mazda: 471 in the register, and 371 Japanese vehicle recall notifications filed in 2024.

The badge is free to use. It links to this page and nowhere else, and it never shows advertising.

No register publishes what happens after the letter. Owners do: tell us, in two taps.
