The contact owns a 2007 Nissan Xterra. When the vehicle was started, the fuel gauge displayed 1/8 less fuel in the tank than the previous night. The contact stated that the failure started approximately three months ago that the fuel gauge did not reflect the actual amount of fuel in the tank. The vehicle was taken to an independent mechanic (firestone in los angeles, California) where it was diagnosed that the fuel sender module failed and needed replacement. The vehicle was not repaired. The manufacturer was notified of the failure and provided case number: 27901980. The approximate failure mileage was 110,000.
Dec. 2014: gas gauge reading became erratic. Contacted dealer who said sensor in tank would have to be replaced at a cost of approximately $400. May 12, 2015, delivered vehicle to dealer to repair gas gauge sensor, also experiencing vibration and rumble at 40 to 45 mph which started 10 days ago (88,000 miles). Dealer informed me that vibration was do to "insulating sleeve" on driveshaft that had broken loose and driveshaft needs to be replaced at a cost of $750. Vibration at 40-45 mph sounds suspiciously similar to problem others have reported as transmission goes out due to coolant contamination.
