2006 Nissan Xterra Owner Comments

problem #3

  • 39,000 miles


The contact owns a 2006 Nissan Xterra. While adding gasoline to the fuel tank, the contact noticed that the fuel gauge would not indicate the correct amount of gasoline. The check engine light illuminated on the instrument panel when the failure occurred. The vehicle was taken to a local mechanic who stated that the fuel sending unit needed to be replaced. There were no prior warnings. A diagnostic test was not performed. The failure mileage was 39000 and the current mileage was 41000.

The contact owns a 2006 Nissan Xterra. The fuel guage did not register the correct amount of fuel that was actually in the fuel tank; at times, it would function correctly. The contact stated when the fuel tank was fuel, the gauge indicated that the fuel was full. The failure occurred everytime the contact fueled the vehicle. The current mileage was 47,783. The failure mileage was approximately 44,000.

Xterra 4WD 6-cyl

  • Automatic transmission
  • 12,000 miles
I have a 2006 Nissan Xterra off-road that was bought new in may of 2006 and now has approximately 12,000 miles. Within the last few weeks a few times the gas gauge has become erratic. After a fill up the gauge will drop to around 3/4 full after only 25+ miles being driven and other times reads correctly as the gas is used. I have checked gas used against odometer mileage and it seems correct -- so no leaks! dealers have been called but no ideas, and it has not been taken in for this complaint yet. I plan on checking the obdii port for error codes prior to taking to dealer.
