For scale, 802 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 months.
Defect
In the continuously variable transmission (CVT) torque converter, the lockup clutch spring was improperly formed during manufacturing. When the lockup mechanism engages, excessive stress is applied to the spring, causing it to break. The broken spring falls into the interior of the torque converter, generating abnormal noise. In the worst case, the spring becomes jammed inside the converter, causing the engine to stall during launch or acceleration and leaving the vehicle unable to move.
Corrective action
On all vehicles, replace the torque converter with a known-good unit.

状況
自動無段変速機（ＣＶＴ）のトルクコンバータにおいて、ロックアップクラッチスプリングの成形が不適切なため、ロックアップ機構作動時に過大な応力がかかり折損することがある。そのため、折損したスプリングがトルクコンバータ内部に脱落して、異音が発生し、最悪の場合、トルクコンバータ内部に噛み込み、発進時等にエンストして走行できなくなるおそれがある。
改善措置
全車両、トルクコンバータを良品と交換する。
