What the ministry says is wrong

 原動機の吸入空気の温度を上昇させ、冷間時の原動機の始動性を向上させるエア・ヒー タにおいて、①エア・ヒータ・リレーの防水・防錆性能不足、または②エア・ヒータ・リ レーの防水・防錆性能不足及びエア・ヒータ制御用コントロールユニットのコンピュータ のプログラムが不適切なため、そのままの状態で使用を続けると、エア・ヒータ・リレー が常時通電状態となり、最悪の場合、エア・ヒータが過熱して周辺の電気配線等が焼損し 、火災に至るおそれがある。

What is to be done about it

 全車両、車両型式を確認し、当該エア・ヒータ・リレーを①防水・防錆対策を行なった 対策品、または②接点の材質変更及び防水・防錆対策を行なった対策品と交換する。

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: その他(エンジン)

168 notices in this register name その他(エンジン). 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 220 Japanese vehicle recall notifications filed in 2002.
