Filing in context

For scale, 443 of the 4,890 filings in this archive report a larger number of affected vehicles; the vehicles involved here were manufactured over a span of about 4 years and 3 months.
Defect
In the wiper system, improper manufacturing of the front wiper motor bottom cover — which houses the electrical circuit — may cause the relay joint with electrical contacts to interfere with the worm wheel. When the wiper is operated with snow accumulated on the cowl panel and then switched off, the wiper arm may be unable to return to its park position. The resulting reaction force on the arm causes the relay joint contacts to repeatedly switch on and off through the worm wheel, generating arc discharge at the contact points. In the worst case, this arc discharge may cause a vehicle fire.
Corrective action
On all vehicles, replace the front wiper motor bottom cover with a corrected part.

状況
窓ふき器において、フロントワイパーモータのボトムカバー（電気回路内蔵）の製造が不適切なため、電気接点付きリレージョイントとウォームホイールが干渉しているものがある。そのため、カウルパネルに雪が積もった状態で窓ふき器を作動後に停止すると、ワイパーアームが本来の停止位置に戻れずアームに反力が発生し、ウォームホイールを介してリレージョイントの接点部がオンオフを繰り返すことで接点部にアーク放電が発生して、最悪の場合、火災に至るおそれがある。
改善措置
全車両、フロントワイパーモータのボトムカバーを対策品に交換する。
