IN DEC 2012 I HAD TO TAKE MY 2006 NISSAN XTERRA TO THE GARAGE, THERE I WAS TOLD THAT MY RADIATOR HAD CRACKED IN 3 PLACES AND THAT I HAD COOLANT IN MY TRANSMISSION. I HAD TO REPLACE THE RADIATOR AND HAVE THE TRANSMISSION FLUSHED SEVERAL TIME. THEN ON APRIL 10 I WAS DRIVING HOME. WHILE GETTING ON THE INTERSTATE MY CHECK ENGINE LIGHT CAME ON AND MY VEHICLE DID NOT WANT TO GO (LIKE IT WASN'T GETTING ANY GAS). TOOK THE XTERRA BACK TO THE GARAGE AND WAS TOLD THAT I NEEDED TO REBUILD OR REPLACE MY TRANSMISSION. I FEEL THAT SO MANY PEOPLE HAVE HAD PROBLEMS WITH THIS THAT NISSAN NEEDS TO DO RECALLS AND REIMBURSE EVERYONE THAT HAS ALREADY HAD THIS PROBLEM. IF THEY WERE ANY KIND OF "GOOD" COMPANY THAT IS EXACTLY WHAT THEY WOULD DO! VERY DISAPPOINTED!!!!!!!!!!!!!!!!!!!!!!!! *TR

RADIATOR FLUID LEAKED INTO MY TRANSMISSION. THIS CAUSED AN ENTIRE SHUTDOWN OF MY TRANSMISSION. I WAS TOLD BY NISSAN THAT IT WOULD TAKE UP TO $5,000 TO REPAIR. THE RADIATOR FLUID LEAKED DUE TO A DEFECT THAT NISSAN COULD HAVE EASILY RECALLED AND AVOIDED. I HAVE CONDUCTED RESEARCH AND FOUND THAT THOUSANDS OF OTHER NISSAN OWNERS HAVE EXPERIENCED THE SAME PROBLEM AND NISSAN IS NOT WILLING TO DO ANYTHING ABOUT IT. I WAS TOLD THAT I WOULD BE RESPONSIBLE FOR THE COST EVEN THOUGH THIS COULD HAVE BEEN EASILY AVOIDED BY NISSAN MANUFACTURERS. *TR

ABOUT 3 WEEKS AGO MY TRANSMISSION STARTED TO SHIFT HARD. TOOK IT TO THE DEALER AND THEY SAID MY RADIATOR ASSEMBLY HAS LEAK INTO THE TRANSMISSION AND THEY KNEW ABOUT THE PROBLEM BUT WONT FIX IT UNDER WARRANTY BECAUSE I WAS OUT OF WARRANTY. I GOT A LETTER FROM NISSAN SAYING THE SAME PROBLEM WITH THE RADIATOR ASSEMBLY AND SHOW THE DEALER IT AS WELL AND THEY STILL WON'T COVER IT FOR BEING OUT OF WARRANTY. SO I ASKED THEM HOW MUCH IT WOULD BE TO FIX IT AND IT WOULD BE $8000.00 TO REPAIR. THE DEALER SUGGESTED I CALL NISSAN. SO I CALL AND TELL THEM MY PROBLEM WITH THE RADIATOR AND TELL SAID THEY WONT COVER IT OF BEING OUT OF WARRANTY. I ASKED NISSAN WHAT I'M SUPPOSED TO DO AND THEY SAID THAT I'M OUT OF LUCK. SO I'M WONDERING WHY THEY DIDN'T HAVE A RECALL ON A KNOW PROBLEM WITH THEIR VEHICLES. *TR

I WAS TRAVELING TO WORK THAT MORNING. I LIVE ON TOP OF A MOUNTAIN SO I WAS GOING DOWN A MOUNTAIN. I STARTED TO HEAR A GRINDING SOUND BETWEEN 40-60 MPH. THEN THE VEHICLE BEGAN TO SHAKE. WHEN I WOULD SLOW DOWN IT BEGAN TO STOP. I GOT TO WORK AND WHEN THE TECHNICIAN LOOKED AT VEHICLE HE STATED THE COOLANT HAD MIXED WITH TRANSMISSION FLUID. I AM IN THE CAR BUSINESS SO I KNEW THAT THIS WAS MAJOR DAMAGE. I CALLED A LOCAL NISSAN DEALER AND TO MY SURPRISE LEARNED THAT THIS IS A WELL KNOW ISSUE WITH THIS VEHICLE. I AM VERY UPSET AND THIS COULD HAVE CAUSED A MAJOR ACCIDENT BEING ON A MOUNTAIN AND HAVING THE TRANSMISSION GO OUT. I HAVE TAKEN VERY GOOD CARE OF THIS VEHICLE AND AM VERY DISPLEASED WITH THE SERVICE. I WROTE A COMPLAINT TO NISSAN NORTH AMERICA AND THE ONLY REPLY I RECEIVED WA TO TELL ME ABOUT AN OPEN RECALL ON THE VEHICLE. WELL SINCE THE VEHICLE CAN'T BE DRIVEN I GUESS THAT RECALL WILL HAVE TO WAIT. I DID REPLACE THE RADIATOR AND FLUSHED THE TRANSMISSION SEVERAL TIMES IN HOPES THAT IT WOULD SAVE THE TRANSMISSION BUT SO SORRY TO SAY I STILL HAVE THE SHUTTER AND VIBRATION AT 40 -60 MPH. THE EXTENDED WARRANTY THAT NISSAN HAS COME UP WITH IS A LAUGH! MOST COMPLAINT I HAVE SEEN THE CONSUMER HAS PROBLEMS WELL AFTER 100000 MILES AND WHY SHOULD THE CONSUMER PAY ANYTHING ON A DEFECTED PART THAT CAUSED THE DAMAGE. SHAME ON NISSAN! *TR

10V517000 · Engine And Engine Cooling

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.

Mar 3, 2010

NISSAN IS RECALLING CERTAIN MODEL YEAR 2006 AND MODEL YEAR 2008 FRONTIER, XTERRA AND PATHFINDER VEHICLES. THE MOLDED FUEL TANK SHELLS CAN DEFORM, CAUSING THE FUEL SENDER FLOAT ARM TO CONTACT AN EMBOSSMENT MOLDED INTO THE TANK SHELL CAUSING THE INSTRUMENT PANEL FUEL GAUGE TO SHOW THAT THE VEHICLE HAS APPROXIMATELY ONE QUARTER TANK WHEN THE FUEL TANK IS EMPTY.

Consequence & remedy

Consequence: THIS COULD CAUSE THE VEHICLE TO RUN OUT OF GAS AND STALL IN TRAFFIC, INCREASING THE RISK OF A CRASH.

Remedy: DEALERS WILL REPLACE THE FUEL LEVEL SENDING UNIT INSIDE THE FUEL TANK WITH A NEW ONE THAT HAS A MODIFIED FLOAT ARM. THIS SERVICE WILL BE PERFORMED FREE OF CHARGE. THE SAFETY RECALL IS EXPECTED TO BEGIN ON OR BEFORE MARCH 22, 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.

Remedy: DEALERS WILL REPLACE THE FRONT CZS WITH A REDESIGNED SENSOR. THE RECALL BEGAN ON JANUARY 26, 2009.
