I also have a 2005 Nissan Pathfinder with the same faulty fuel sensor that Nissan used in many of its vehicles. I also cannot trust my fuel gauge and actually have run out of fuel with my family in the car on a busy road. Of course, when running out of fuel you lose power steering and power assist on your brakes as well. Nissan will now sell the senor separate from the fuel pump, but it is still around $75.00-80.00 in cost and than you will need to have a new gasket ring, and that is round $15.00. Because the fuel tank needs to be removed from the vehicle to replace the sensor, it may be difficult for you to perform this service yourself. Also, consider the hazards of flammable fuel in the tank if you attempt to do this yourself.
By the way, recently Nissan has finally acknowledged this defective senor on 54,000 of their models, but claim when I called them about mine that it was not part of the recall. To me it seems as though this issue is greater than Nissan wants to admit and just like Toyota’s recent issues, they had a knee jerk reaction to the possibilities of legislative hearings. But, in my opinion, as well as others Nissan has not done enough to ensure customer satisfaction, or perceived reliability in the quality of their vehicles.
That being said, I was recently in the market to purchase a new minivan for my wife, and looked at the Nissan Quest, along with others. After reading this vehicle’s reviews online as well as Nissan’s refusal to take ownership of my faulty fuel sensor, I decided I could not afford to purchase another Nissan vehicle with the possibility of having the same faulty fuel sensor, or other quality issues that Nissan will not take ownership of fixing.
