Usually on long trips the Slip and VDC light comes on, then Speedometer needle fluctuates, then Brake and ABS lights come on, then AC blows warm, and finally lose power. After shutting the engine off, it takes several hours before it will restart.

Potential Fuel Leak

The fuel pressure sensor may not have been sufficiently tightened during vehicle production. As a result, the fuel pressure sensor may loosen over time resulting in a fuel leak. Any fuel leak increases the risk of a fire. Nissan / Infiniti dealers will replace the fuel pressure sensor as necessary to correct this concern.

Driver's Front Airbag

In the affected vehicles the driver's front airbag may have been manufactured with and incorrect part. This part may block the flow of propellant when the airbag is deployed. This could cause the airbag to rupture, increasing the risk of personal injury. Dealers will replace the driver's front airbag to correct this concern.

Fuel Leak from Fuel Pressure Sensor

On certain vehicles, the fuel pressure sensor may not have been tightened to the correct specification. As a result, the fuel pressure sensor may loosen due to heat and vibration, causing a fuel leak. Fuel leaks always increase the risk of a fire. Dealers will replace the fuel pressure sensor to correct this concern.

When they called an Infiniti parts dealer, the dealer let it be known that it was a design defect and that they keep the headl...
