What the ministry says is wrong

ダイナミック・スタビリティ・コントロールユニットにおいて、ヨーレートの特性異常を検知するプログラムが不適切なため、正しく判定できない。そのため、ヨーレートの特性異常が発生しても故障判定できず、ＴＣＳ／ＤＳＣ作動表示灯が点灯しないおそれがある。 ＴＣＳ・・・トラクションコントロールシステム：水にぬれた路面や雪道等の滑り易い路面での発進や旋回加速時に起こる駆動輪の空転を防ぎ、適切な駆動力と操縦性を確保するシステム ＤＳＣ・・・ダイナミック・スタビリティ・コントロール：滑り易い路面での走行時や、緊急回避など急激なハンドル操作による車両の横すべりを抑えるため、ＡＢＳやＴＣＳ等によりブレーキやエンジンの出力を自動的に制御し、車両の安定性を確保するシステム

What is to be done about it

全車両、ダイナミック・スタビリティ・コントロールユニットを対策品に交換する。なお、交換部品の準備に時間を要することから、準備ができ次第、改めて案内する。

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: コンピュータ(制御装置)

19 notices in this register name コンピュータ(制御装置). 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 380 Japanese vehicle recall notifications filed in 2025.
