AFTER FILLING UP MY GAS TANK, I TURNED ON THE CAR, AT WHICH POINT THE NEEDLE DID NOT REGISTER THE FULL TANK. AFTER DRIVING A COUPLE MILES, THE CHECK ENGINE LIGHT CAME ON. I WENT DIRECTLY TO THE DEALER AND WAS TOLD THAT IT WAS A FUEL SENDING UNIT/SENSOR AND THAT IT WAS NO LONGER COVERED AFTER 30K MILES. AFTER RETURNING HOME AND DOING RESEARCH, I WENT ONLINE TO X.NISSANHELP.COM AFTER PERFORMING A SEARCH, I CAME ACROSS COUNTLESS OTHERS WHO HAVE EXPERIENCED THE SAME PROBLEM. APPARENTLY IT HAS SOMETHING TO DO WITH THE FUEL SENDING UNIT. A SIMILAR PROBLEM WAS FOUND ON THE 2000-2004 XTERRA MODELS AND A RECALL WAS PERFORMED WHEN THE VEHICLE WOULD STOP AFTER NOT GETTING ANY FUEL, POSING A GREAT DANGER. IT SEEMS THAT SOMETHING IN THE UNIT IS FAULTY AND WILL CORRODE OVER TIME. THERE IS A GENERAL CONSENSUS THAT EVERYONE WHO IS HAVING THE PROBLEM IS EXPERIENCING THE SAME THING AFTER HAVING THE VEHICLE FOR OVER 2 YRS AND WITH AROUND 39K-49K. IF THIS PROBLEM EXISTED IN PREVIOUS MODELS, AND IT WAS RECALLED, THE 2005-2007 XTERRAS, FRONTIERS, AND PATHFINDERS SHOULD GET THIS FIXED AT NO CHARGE TO THE CUSTOMER!! WHY WAIT FOR ACCIDENTS AND POSSIBLE DEATHS, ESPECIALLY SINCE THE PROBLEM LIES IN AN INTEGRAL PART OF THE VEHICLE. COST OF REPAIR RANGES FROM $300-600." *TR

On February 29, 2012 the National Highway Traffic Safety Administration (NHTSA) received a letter petitioning the agency to conduct a defect investigation into MY 2005-2010 Nissan Pathfinder, Frontier, and Xterra vehicles [the subject vehicles] for automatic transmission failures related to failed transmission coolers.NHTSA conducted a comprehensive review of data related to this subject. Our report, documenting this review, is available in the document file for this defect petition.It will also be published in the Federal Register. Of the 2,505 referenced complaints, 638 relate to a potential hazard (unable to maintain speed, no motive power, engine stall) and 1,867 concern customer satisfaction issues including, but not limited to, repair cost, vehicle shudder and shake, and engine overheating.Taking into account the allocation of agency resources and priorities and the likelihood that additional investigation would result in a finding that an unreasonable risk to highway safety exists, we conclude that further investigation is not warranted and deny the petition.ODI Complaint ID numbers are referenced on the next page.
