Filing in context
This is the only filing in the archive that cites the Fuel common rail system as the affected component. This filing is one of 44 Mitsubishi notifications from 2009 in this archive. For scale, 4,359 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 2 years and 2 months.
Defect
In the fuel injection system, improper machining of the fuel supply pump during manufacturing causes cracks to develop inside the pump, allowing fuel to leak and mix with the engine oil. Continued use causes the fuel-contaminated oil to be drawn through the blow-by gas passage into the intake manifold and burned inside the cylinders, resulting in engine over-revving, engine shutdown, and inability to restart. In the worst case, fuel-contaminated engine oil may leak and cause a vehicle fire.
Corrective action
On all vehicles, replace the fuel supply pump with a correct unit.

状況
燃料噴射装置において、燃料供給ポンプの製造時の加工が不適切なため、当該ポンプの内部に亀裂が発生し、燃料が漏れ、エンジンオイルに混入するものがある。そのため、そのままの状態で使用を続けると、燃料の混入したオイルがブローバイガスの通路を経由して吸気管に吸入されシリンダー内で燃焼するため、エンジン回転の上昇、エンジン停止及び再始動不能となり、最悪の場合、燃料の混入したエンジンオイルが漏れ火災に至るおそれがある。
改善措置
全車両、燃料供給ポンプを良品と交換する。
