THIS '05 XTERRA HAD A THOROUGH CHECK OUT & DIAGNOSTIC. THEN 500 MILES LATER, AT AROUND 46000 MILES, WHEN THE FUEL INDICATOR WAS AT 1/2 TANK- THE NEEDLE SUDDENLY PLUNGED TO BELOW EMPTY, A LIGHT CAME ON AND THE SERVICE ENGINE SOON LIGHT CAME ON. THIS WAS ALL VERY ALARMING, AND WE WERE STUCK IN BUMPER-BUMPER TRAFFIC IN A BAD PART OF PHOENIX WHEN IT HAPPENED. IT WASN'T HOT OUT, JUST A BIG TRAFFIC JAM IN 5:00 RUSH, AND WE WERE NOWHERE NEAR A GAS STATION. IT WAS TERRIBLE, AND WE WERE VERY SCARED TO BE STRANDED. AFTER THAT WE BOUGHT A HUGE GAS CAN, AND JUST DROVE AROUND WITH 10 GALLONS OF GAS JUST IN CASE. THAT IS TERRIBLE, TO HAVE TO DRIVE WONDERING IF WHEN YOU'LL ACTUALLY RUN OUT OF GAS, VS. JUST BEING TOLD YOU ARE OUT OF GAS.THIS STARTED HAPPENING DURING THE BEGINNING OF OUR CROSS-COUNTRY TRIP TO THE COAST AND BACK. IT WAS AN ISSUE THE ENTIRE TIME, AND VERY NERVE WRACKING. NISSAN SHOULD FIX THIS, SINCE I'VE RETURNED FROM OUR TRIP AND FOUND THAT 100'S OF PEOPLE ARE HAVING EXACT SAME PROBLEM! THIS IS A FAULTY PART, AND IT MAKES ME WONDER WHAT ELSE WILL GO WRONG. THIS IS THE FIRST NISSAN OUR FAMILY HAS HAD, AND I AM AFRAID WE MIGHT NOT BE BUYING ANOTHER ONE, AND TELLING OTHERS TO STEER CLEAR OF NISSAN. *TR

2005 NISSAN XTERRA SE, FUEL SENDING UNIT IS ERRATIC AND DOESN'T READ PROPER AMOUNT OF FUEL IN TANK. THIS COULD BE A SERIOUS SAFETY CONCERN FOR ANYONE WHO ACTUALLY USES THEIR TRUCK OUT IN THE DESERT THINKING THEY HAVE MORE FUEL THEN IS INDICATED. QUITE OFTEN THE GAUGE WILL DROP DOWN TO EMPTY AND I'VE GONE TO FILL THE TRUCK UP JUST IN CASE AND END UP PUTTING ONLY A FEW GALLONS OF FUEL IN THE TRUCK. THIS HAS HAPPENED MULTIPLE TIMES, ALTHOUGH ITS NOT A SAFETY CONCERN I DO BELIEVE THAT THE GAUGE SHOWING THE TANK IS AT 3/4 OR MORE THEN DROPPING DOWN TO 1/4 TANK (THE ACTUAL AMOUNT OF FUEL) IS ONE. MY BIGGEST COMPLAINT IS THAT NISSAN HAS ISSUED A RECALL FOR MODELS EARLIER THEN THE 2005 AND THE MODELS FROM 2006 FORWARD. WHY IS IT THAT THESE MODELS GET THE RECALL AND NOT THE 2005 MODELS? THE COMPONENT THAT IS FAILING IN BOTH THE EARLIER AND LATER MODELS IS THE EXACT SAME PART. *TR

NO SPECIFIC EVENTS LEADING TO FAILURE. STANDARD USE OF THE 2005 NISSAN XTERRA AND THE FAILURE HAS OCCURRED AT APPROXIMATELY 70K MILES ON THE CAR.. THE FAILURE IS THE FUEL SENSOR GAUGE WHICH CAUSES THE GAS GAUGE TO BE INACCURATE AT ALL TIMES. IT WILL GO FROM FULL TO EMPTY IN 1 SECOND WHILE YOU ARE HEADED DOWN THE ROAD. OTHER TIMES IT WILL SHOW HALF TANK WHEN THE TANK IS EMPTY. IT HAPPENS EVERY TIME WE ARE IN THE CAR. CONSEQUENCES COULD BE FATAL IF WE HAD NOT CAUGHT ON TO THE ISSUE. AT ANY POINT WE RUN THE RISK OF RUNNING OUT OF GAS DUE TO AN ERROR IN THE WAY THE GAUGE IS READING.. WE ARE FORCED TO TRACK MILES ON THE ODOMETER EACH TIME WE FILL UP. NOTHING HAS BEEN DONE BY ME AT THIS POINT. NISSAN HAS ACKNOWLEDGED THE ISSUE BY RECALLING 2006+ MODELS AND EXTENDING THE WARRANTY TO 72K MILES ON THE 2005 MODELS. OUR CAR NOW HAS 90K MILES ON IT SO WE DO NOT MEET EITHER OF THEIR "SAFETY" FIXES. *TR

Official recalls

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.
Dec 29, 2008

IN THOSE AREAS OF THE COUNTRY WHICH USE HEAVY CONCENTRATIONS OF ROAD SALT IN THE WINTER, A MIXTURE OF SNOW/WATER AND SALT CAN ENTER INTO THE FRONT CRASH ZONE SENSOR (CZS) HOUSING. 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.
Remedy: DEALERS WILL REPLACE THE FRONT CZS WITH A REDESIGNED SENSOR. THE RECALL BEGAN ON JANUARY 26, 2009. OWNERS IN THE OTHER STATES WILL RECEIVE EXTENDED WARRANTY COVERAGE FOR THE SENSOR TO 10 YEARS.

ON CERTAIN SPORT UTILITY VEHICLES EQUIPPED WITH A NISSAN ACCESSORY TOW HITCH, INADEQUATE QUALITY OF SOME WELDED JOINTS IN THE HITCH ASSEMBLY MAY RESULT IN SEPARATION OF THE HITCH FROM THE VEHICLE WHEN BEING USED TO TOW.
Consequence & remedy
Consequence: THIS COULD RESULT IN THE TRAILER SEPARATING FROM THE VEHICLE AND CAUSE A CRASH WITHOUT WARNING.
Remedy: DEALERS WILL REPLACE THE TOW HITCHES. ON OCTOBER 17, 2005, OWNERS WERE SENT AN INTERIM LETTER ADVISING THEM NOT TO USE THE TOW HITCH UNTIL IT CAN BE REPAIRED. ANOTHER LETTER WAS SENT OUT ON NOVEMBER 21, 2005, NOTIFYING THEM TO BRING THEIR VEHICLES IN FOR REPAIR. OWNERS MAY CONTACT NISSAN AT 1-800-647-7261.
