TypeStatutory Recall (government-mandated recall)
Date filedJuly 21, 2022

Defect

In the continuously variable transmission (CVT), an incorrect control program in the CVT controller may cause the steel belt to slip and generate wear debris during high-load kickdown operation. Continued use allows the wear debris to cause sticking in the hydraulic pressure control valve, resulting in insufficient hydraulic pressure. In the worst case, the vehicle may become inoperable.

Corrective action

Inspect the CVT on all vehicles; if belt slippage is determined to have occurred, replace the CVT. Reprogram the CVT controller with the corrected/updated software on all vehicles. If the CVT was not replaced at the time of the recall and belt slippage is subsequently confirmed, the CVT will be replaced at no charge.

状況

無段変速機(CVT)において、CVTコントローラの制御プログラムが不適切なため、高負荷のキックダウン時等に、変速機構であるスチールベルトが滑り摩耗紛が発生する場合がある。そのままの状態で使用を続けると、摩耗紛による油圧調整弁の摺動不良が起こり油圧不良となることで、最悪の場合、走行不能に至るおそれがある。

改善措置

全車両、CVTを点検し、ベルト滑りがあると判断した場合は、CVTを交換する。また全車両、CVTコントローラを対策プログラムに書き換える。 なお、CVTを交換しなかった場合において、後日ベルト滑りがあると判断した場合は、CVTを無償交換する。
