Infiniti M56, QX56: Fuel System
Affects Infiniti M56, QX56 · 2011–2012 — about 7K vehicles.
The hazard
On certain vehicles, the fuel pressure sensor connected to the engine fuel delivery rail may not have been sufficiently tightened during vehicle assembly. Should the pressure sensor loosen, fuel could leak past a gasket used in the connection between the sensor and rail. Fuel leakage, in the presence of an ignition source, could result in a fire causing property damage and/or personal injury. Correction: Dealers will inspect for fuel leakage from the pressure sensor and the fuel rail. If there are no signs of a fuel leak, the fuel pressure sensor will be tightened to specifications. If a fuel leak is confirmed, the gasket between the sensor and the fuel delivery rail will be replaced, and the sensor will be tightened.
