Hazard
The lock mechanism in the hydraulic camshaft adjuster of gasoline engines has inadequate material properties, resulting in insufficient durability. As the lock mechanism wears, abnormal noise may occur during engine start-up. In the worst case, the engine warning light (MIL) may illuminate, causing the catalyst heating control to stop, which could result in exhaust emissions failing to meet regulatory standards.

ガソリンエンジンの油圧カムシャフトアジャスタにおいて、ロック機構の材質が不適切なため、耐久性が不足している。そのため、当該ロック機構が摩耗しエンジン始動時に異音が発生して、最悪の場合、エンジン警告灯（ＭＩＬ）が点灯して触媒加熱制御を停止させることで、排出ガスが規制値を満足しなくなるおそれがある。
Remedy
Replace the hydraulic camshaft adjuster with the corrective part on all vehicles.
