Hazard
In the gasoline engine exhaust manifold, strength evaluation was insufficient when welding conditions were changed. As a result, cracks may develop at the weld due to thermal cycling and vibration. This could cause exhaust gas leakage to exceed emission standards during high-RPM operation such as driving uphill.

（３）ガソリンエンジンのエキゾーストマニホールドにおいて、パイプの溶接条件変更時の強度検討が不十分なため、冷熱の繰返しや振動等により当該溶接部に亀裂が生じるものがある。そのため、登坂路走行等の高回転時に排出ガスが漏れ基準値を満足しなくなるおそれがある。
Remedy
Replace the exhaust manifold with a serviceable unit on all vehicles.
