Defect
On the engine accessory drive belt auto-tensioner, the mounting flange geometry was improperly designed. As the tensioner bearing wears over time and sliding resistance increases, repeated high-load operation may cause a crack to develop in the flange. Continued use may cause the flange to fracture, allowing the accessory drive belt to disengage. In the worst case, this illuminates a warning light, increases steering effort, and may lead to battery discharge or engine overheating.
Corrective action
On all vehicles, inspect the accessory drive belt auto-tensioner and, if a pre-corrected unit is found, replace it together with its mounting bolt with a corrected/revised part.

状況
エンジンの補機駆動ベルト用オートテンショナーにおいて、取り付けフランジ部の形状が不適切なため、オートテンショナーのベアリングが経年変化で摩耗し摺動抵抗が増大した状態で高負荷運転を繰り返した場合にフランジ部に亀裂が発生することがある。そのため、そのまま使用を続けるとフランジ部が破損し、最悪の場合、当該ベルトが外れ、警告灯が点灯し、ステアリング操舵力が増大するとともに、バッテリー上がりやオーバーヒートに至るおそれがある。
改善措置
全車両、点検のうえ、補機駆動ベルト用オートテンショナーが対策前品の場合は取り付けボルトとともに対策品と交換する。
