Overview
| MLIT filing number | 1136710 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | November 12, 2015 |
| Manufacturer(s) | Honda |
| Component | Continuously Variable Transmission (CVT) |
| Production period | December 12, 2011 — April 25, 2014 |
| Vehicles affected | 105,351 units |
Defect
On vehicles equipped with paddle shifters, a software deficiency in the engine control unit (ECU) allows an excessively high load to be applied to the continuously variable transmission (CVT) drive pulley shaft when the driver shifts from 2nd to 1st gear via the paddle shifter during deceleration with the accelerator released. Repeated occurrence of this condition may cause the shaft to fracture. In the worst case, the vehicle may become inoperable.
Corrective action
On all affected vehicles, check the on-board service diagnostic data recorder; if the load history on the drive pulley shaft is within the specified value, reprogram the engine control unit with the corrected/updated software. If the load history exceeds the specified value, replace the CVT with a new unit and reprogram the engine control unit with the corrected/updated software.

状況
パドルシフト搭載車において、エンジン制御コンピュータ（ＥＣＵ）のプログラムが不適切なため、アクセルペダルから足を離した減速中にパドルシフト操作により２速から１速へ変速すると、無段変速機のドライブプーリシャフトに高い負荷が加わることがある。そのため、その状態を繰り返すとシャフトが折損し、最悪の場合、走行不能となるおそれがある。
改善措置
全車両、車載のサービス診断記録装置を確認し、ドライブプーリシャフトへの負荷状態が基準値以内の場合は、エンジン制御コンピュータを対策プログラムに書き換える。基準値以外の場合は、無段変速機を新品と交換するとともに、エンジン制御コンピュータを対策プログラムに書き換える。
