Overview
| MLIT filing number | 1150690 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | December 2, 2021 |
| Manufacturer(s) | Honda |
| Component | Continuously Variable Transmission (CVT) |
| Production period | June 12, 2018 — September 2020 |
| Vehicles affected | 85,390 units |
Defect
On continuously variable transmissions (CVT), the hydraulic control software is incorrectly calibrated. Repeatedly opening and closing the accelerator at a steady vehicle speed may cause the metal drive belt to develop a crack and fracture. Continued operation after fracture results in poor acceleration and launch performance and, in the worst case, may render the vehicle inoperable.
Corrective action
On all vehicles, inspect the CVT for metal belt fragments. If fragments are found, replace the CVT with a good unit and reprogram the CVT hydraulic control software with the corrected program. If no fragments are found, reprogram the CVT hydraulic control software with the corrected program and install an updated fault detection program. If, after the update, the shift position indicator light flashes and the defect is confirmed, the CVT will be replaced at no charge.

状況
無段変速機において、油圧制御プログラムが不適切なため、一定車速での走行時にアクセルの開閉を頻繁に繰り返す操作を行うと、金属ベルトに亀裂が生じ破損することがある。そのため、そのまま使用を続けると、発進、加速不良となり、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、無段変速機の金属ベルト破損片の有無を点検し、破損片が確認された場合は無段変速機を良品と交換するとともに、無段変速機の油圧制御プログラムを対策プログラムに書き換える。破損片が確認されなかった場合は無段変速機の油圧制御プログラムを対策プログラムに書き換え、故障検知プログラムを追加し、追加後にシフトポジション表示灯が点滅し、当該不具合が確認された場合には、無段変速機を無償交換する。
