Filing in context
The Fuel Pump is the most frequently cited component category in this archive, appearing in 57 of its 4,890 filings. This filing is one of 44 Mitsubishi notifications from 2009 in this archive. For scale, 4,554 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 3 months.
Defect
In the fuel injection system, improper machining of the fuel supply pump during manufacturing causes an internal crack to develop in the pump, allowing fuel to leak into the engine oil. Continued use causes the fuel-contaminated oil to be drawn through the blowby gas passage into the intake manifold and burned in the cylinder, causing engine speed to surge, engine stall, and inability to restart. In the worst case, fuel-contaminated engine oil may leak and result in a vehicle fire.
Corrective action
On all vehicles, replace the fuel supply pump with a non-defective 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。
