THERE WAS NO SPECIFIC EVENT LEADING UP TO FAILURE; I PURCHASED MY CERTIFIED PRE-OWNED '05 XTERRA 4 MONTHS AGO AND DROVE IT UP UNTIL YESTERDAY WITHOUT PROBLEM. WHEN I TURNED ON MY VEHICLE AFTER WORK, MY "SERVICE ENGINE SOON" LIGHT WAS ON. I STOPPED TO FILL UP WITH GAS ON MY WAY HOME, AND NOTICED MY GAS GAUGE WOULD NOT PASS THE 3/4 TANK POSITION. EVENTUALLY, AFTER DRIVING ABOUT 50 MILES OR SO, MY GAS GAUGE (SOMETIMES) RETURNS TO ITS NORMAL POSITION. THE "SERVICE ENGINE SOON" LIGHT ALWAYS REMAINS ON. AT THIS POINT, NO CORRECTIVE MEASURES HAVE BEEN TAKEN. BUT IN DOING MY RESEARCH, ALL SIGNS POINT TOWARDS THIS BEING A FUEL SENDING UNIT PROBLEM THAT IS COMMON IN BOTH 01-04 NISSAN VEHICLES (FOR WHICH THERE WAS A RECALL) AND 05-PRESENT NISSAN VEHICLES (FOR WHICH THERE HAS BEEN NO RECALL). *TR

THE ANCHOR PINS FOR THE ASSIST CYLINDERS ON THE REAR HATCH ARE RUSTING BADLY. I'VE TOLD MY WIFE NOT TO OPEN THE HATCH UNTIL THE DEALER CAN GET IN NEW PARTS WE ORDERED. WE ASKED THE DEALER IS THIS HAS BEEN A PROBLEM AND THEY SAID NO. SINCE WE DID NOT BUY THE EXTENDED WARRANTY AND MILEAGE IS 86000 THIS WOULD NOT BE COVERED UNDER WARRANTY. I CONTACTED NISSAN USA AND GOT THE SAME ANSWER. THE REAR HATCH IS MADE FROM METAL AND IS HEAVY. IF ONE OF THESE RUSTY PINS FAILS THE HATCH WILL FALL ON SOMEONE'S HEAD. THIS SHOULD BE A RECALL TO CHECK THE PINS FOR RUSTING AND REPLACED IF THEY ARE RUSTED. THE NEW PARTS ARE REDESIGNED AND I WONDER WHY THE PART WAS REDESIGNED? 2005 WAS THE FIRST YEAR OF THIS BODY STYLE SO THERE MAY HAVE BEEN PROBLEMS IN SOME OF THE COMPONENTS USED ON THIS VEHICLE. THE NEW PARTS ARE ABOUT $60.00 AND I'LL PUT THEM ON. HOW MUCH WOULD IT COST NISSAN IF THIS HATCH FALLS ON MY WIFE? *TR

THERE SHOULD DEFINITELY BE A RECALL ON THESE FUEL SENDERS AND ISSUE SOME KIND OF CREDIT OR CHECK FOR THE OWNERS WHO HAVE ALREADY HAD THE VEHICLE REPAIRED AT THEIR EXPENSE. *TR

NOW MY SES LIGHT COMES ON INDICATING A FUEL SYSTEM (FUEL SENSOR GAUGE) PROBLEM. AS I KNOW THAT I AM ONE OF VERY MANY XTERRA AND PATHFINDER OWNERS WITH THE SAME PROBLEM, IT WOULD APPEAR THAT THIS ITEM IS DEFECTIVE. I ALSO OWNED THE 2000 XTERRA - THERE WAS A RECALL ON THE FUEL SYSTEM AND IT WAS REPLACED. WHY IS THERE NOT A RECALL NOW - SINCE NISSAN IS OBVIOUSLY DOING NOTHING TO REMEDY THIS SITUATION. *TR

I FILLED UP MY GAS TANK AND WHEN I TURNED MY CAR ON, THE GAS GAUGE NEEDLE DID NOT MOVE TO REFLECT HOW MUCH GAS WAS IN MY TANK. THE GAS STATION ATTENDANT PUT ANOTHER DOLLAR WORTH OF GAS INTO MY CAR. UPON TURNING MY CAR BACK ON, THE GAS GAUGE NEEDLE STILL DID NOT MOVE AND MY "CHECK ENGINE SOON" LIGHT CAME ON. THE GAS CAP WAS SECURE. I CALLED THE DEALER AND TOOK MY CAR INTO THEIR SERVICE DEPARTMENT. THE MECHANIC TOLD ME THEY COULD FIND NOTHING WRONG WITH MY CAR AND RESET THE LIGHT. THE SAME PROBLEM OCCURRED THE NEXT TIME I FILLED MY GAS TANK. FURTHERMORE, ABOUT A MONTH AFTER THE "CHECK ENGINE SOON" LIGHT CAME BACK ON THE GAS GAUGE WILL NOW DROP BELOW EMPTY AND MY GAS LIGHT WILL GO ON WHEN I HAVE ABOUT A HALF OF A TANK OR A QUARTER OF A TANK OF GAS LEFT. THE "CHECK ENGINE SOON" LIGHT REMAINS ON. *TR

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.

IF THIS OCCURS, THE CZS MAY INTERNALLY RUST RESULTING IN A SIGNAL INTERRUPTION. IF THIS HAPPENS, THE RED AIR BAG WARNING LIGHT WILL ILLUMINATE TO ALERT THE VEHICLE OPERATOR.

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.
