NISSAN FRONTIERS AND XTERRAS (AND MAYBE OTHER SIMILAR VEHICLES FROM NISSAN) ARE HAVING A STRONG RECURRING PROBLEM WITH THE FUEL SENDING UNIT SENSOR GOING BAD AND DEALERSHIPS NOT COVERING THIS PART. I HAVE RECENTLY EXPERIENCED THIS SAME FAILURE, WHICH HAS HIT EVERYONE I KNOW WITH A 2005-PRESENT NISSAN FRONTIER.

AT ABOUT 80,000KMS THE FUEL LEVEL SENSOR FAILED. I TOOK IT INTO MY LOCAL NISSAN DEALERSHIP AND WAS TOLD THAT IT WOULD COST ABOUT $700CDN TO REPAIR IT. THE SERVICE TECHNICIAN WAS VERY EAGER TO GET IT FIXED FOR ME, BUT I DECLINED. THE FUEL GAUGE READS EMPTY WHEN THE TANK IS FULL AND AT A CERTAIN POINT IT READS HALF FULL BUT IT NEVER READS FULL. THE SERVICE ENGINE SOON LIGHT IS ALWAYS LIT. APPARENTLY THIS IS A COMMON PROBLEM WITH THE FRONTIERS AND PATHFINDERS, BUT NISSAN HAS DONE NOTHING ABOUT IT. WILL STICK WITH TOYOTA CARS IN THE FUTURE. *TR

THE FUEL GAGE DOES NOT REGISTER "FUEL" PROPERLY ON BOTH COMPUTER & GAGE EVERY TIME WE FILL UP THE TANK. THE SERVICE ENGINE SOON LIGHT STAYS ON CONSTANTLY. WHEN YOU FILL UP THE TANK, THE GAGE GOES TO EMPTY AND LOW FUEL LIGHT COMES ON. THE COMPUTERS SHOWS A READING THAT SAYS -------. EVENTUALLY GAGE WILL SLOWLY GO BACK UP TO FULL AND THE MILES LEFT WILL SHOW ON COMPUTER. WHEN IT GETS DOWN TO HALF TO QUARTER FULL, "MILES LEFT" NO LONGER APPEAR AND FUEL STOPS REGISTERING ON THE GAGE. THIS IS A 2005 NISSAN FRONTIER NISMO CREW CAB TRUCK WITH ONLY 53,000 MILES. MY UNDERSTANDING IS THAT IT IS ERROR CODE P0463 AND THAT OUR TRUCK NEEDS A NEW FUEL SENDING UNIT. APPARENTLY THERE ARE MANY NISSAN VEHICLES THIS IS HAPPENING TOO. THE COST IS APPROXIMATELY $600 WHICH IS RIDICULOUS ON A VEHICLE WITH ONLY 53,000. THERE IS OBVIOUSLY A DEFECT IN THIS PART AND NISSAN SHOULD RECALL THIS PART. *TR

"I HAD 1/4 OF A TANK OF GAS AND WENT TO FILL UP. 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 MANY 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

Oct 28, 2010

NISSAN IS RECALLING CERTAIN MODEL YEAR 2004-2006 ARMADA, TITAN, INFINITI QX56 AND MODEL YEAR 2005-2006 FRONTIER, PATHFINDER AND XTERRA VEHICLES. THE INTELLIGENT POWER DISTRIBUTION MODULE (IPDM) ASSEMBLY CONTAINS AN ENGINE CONTROL MODULE (ECM) RELAY THAT HAS A DIODE FOR ELECTRICAL CURRENT NOISE REDUCTION. THE ECM RELAY MAY ALLOW SILICON VAPOR TO FORM AND, OVER TIME, THE SILICON EVAPORATES FROM THE DIODE MOLDING WHICH CAUSES SILICON OXIDE TO DEVELOP ON THE ECM RELAY CONTACT DUE TO ARCING.

Consequence & remedy

Consequence: THIS COULD CAUSE ENGINE STALLING INCREASING THE RISK OF A CRASH.

Remedy: DEALERS WILL REPLACE THE ECM RELAY INSIDE THE IPDM ASSEMBLY. THIS SERVICE WILL BE PERFORMED FREE OF CHARGE. THE SAFETY RECALL BEGAN ON DECEMBER 6, 2010. OWNERS MAY CONTACT NISSAN AT 1-800-647-7261.

Consequence & remedy

Consequence: THIS ISSUE COULD RESULT IN THE NON-DEPLOYMENT OF THE DRIVER AND PASSENGER FRONT AIR BAGS IN A CRASH, INCREASING THE RISK OF PERSONAL INJURY.

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.
