I TOOK MY PATHFINDER IN TO THE LOCAL NISSAN DEALER FOR A CHECK UP--CHUGGING AT 35MPH, CHECK ENGINE LIGHT SPORADICALLY GOES ON AND OFF, GAS GAUGE STOPPED FUNCTIONING. NISSAN RAN THE DIAGNOSTICS AND TOLD ME THE CHECK ENGINE LIGHT IS BECAUSE I NEED TO PAY $500.00 TO REPLACE THE FUEL SENSOR. I BELIEVE THIS IS A PART THAT WAS PREVIOUSLY RECALLED. I DON'T KNOW IF NISSAN CONSIDERS THE FIX ONCE AND DONE BUT VEHICLES DRIVEN IN SALT AND SAND WINTER CONDITIONS WILL NEED EXTRA ATTENTION. THE TRANSMISSION TROUBLE IS SOMETHING NISSAN KNOWS ABOUT BUT REFUSES TO RECALL. I WAS TOLD I NEEDED TO REPLACE THE RADIATOR AND TRANSMISSION--OVER $5000.00. IF NISSAN KNOWS ABOUT THESE PROBLEMS, WHY MUST I, A NOW UNHAPPY OWNER, PAY FOR THESE REPAIRS?

I FOUND OUT THERE WAS A CLASS ACTION SUIT AGAINST NISSAN FOR THIS PROBLEM. THIS IS REALLY TERRIBLE THEY WON'T ADMIT MANUFACTURERS FAULT IN THIS. SO NOW STILL HAVE TO MAKE PAYMENTS FOR THE CAR WE CAN'T EVEN DRIVE FOR ANOTHER 2 YEARS AND THE REPAIRS CAME AT OVER $7000. CAR IS A NECESSITY TO PEOPLE TO MAKE A LIVING FOR THEIR FAMILIES. WE HAVE 3 SMALL CHILDREN THAT HAVE TO GET TO SCHOOL AND DAYCARE SO THANKS NISSAN YOU LOST ANOTHER CUSTOMER. HOPE EVERYONE STOPS BUYING YOUR CARS.

MY CARS RADIATOR CRACKED AND LEAKED INTO THE TRANSMISSION. THE MIX OF COOLANT AND TRANSMISSION FLUID DAMAGED THE TRANSMISSION AND QUITE POSSIBLY DAMAGED MY ENGINE. NISSAN KNOWS ABOUT THE RADIATOR BECAUSE THEY EXTENDED THE WARRANTY ON IT. THE REPAIRS FOR THIS INCIDENT ARE HIGH THE NISSAN DEALER I TOOK IT TO QUOTED ME $4,591.43 TO REPLACE THE TRANSMISSION AND THE RADIATOR AND THAT IS WITH THE WARRANTY THEY CLAIM THEY HAVE ON IT. THE DEALER ALSO TOLD ME ANY OTHER DAMAGE CAUSED BY THIS FAULTY RADIATOR WOULD NOT BE COVERED AND I WOULD HAVE TO PAY FOR THE REPAIRS TO ANY OTHER COMPONENTS AS WELL THEY TOLD THEY ME MIGHT BE AN ADDITIONAL $2,000 SO NEARLY $7,000. I HAD KNOW CHOICE BUT SELL THE CAR OFF AS SCRAP AS THE REPAIRS WOULD COST MORE THAN THE CAR ITSELF. A FAILURE OF ALL THESE PARTS AT ONCE IS A SAFETY HAZARD TO EVERYONE.

I AM IN THE MIDDLE OF A ROAD TRIP WITH MY CHILDREN AND SUDDENLY MY PATHFINDER WOULD NOT ACCELERATE GOING UPHILL. I THANKFULLY MADE IT UP THE HILL AND ONTO A HIGHWAY ON RAMP. THE GRACE OF GOD IS ALL THAT KEPT ME FROM BEING STRUCK BY A TRACTOR TRAILER TAKING THE SAME EXIT. THE PATHFINDER SHUDDERED AND I PULLED INTO THE SHOULDER (A BLESSING THAT THERE WAS JUST ENOUGH SPACE FOR ONE) AND IT TURNED OFF RIGHT THERE. NOT EVEN 85,000 MILES ON AN '06 PATHFINDER AND I HAD TO HAVE THE STEERING COLUMN REPLACED AFTER SOMETHING BROKE IT IN IT 2 YRS AGO, NOW THIS. I HAD IT TOWED TO THE CLOSEST NISSAN DEALER, 35 MILES FROM WHERE IT STOPPED AND HUNDREDS OF MILES FROM HOME. THE DEALER TOLD ME IT WAS THE KNOWN ISSUE WITH THE CHEAP PLASTIC RADIATORS AND TRANSMISSION. I AM NOW IN A RENTAL CAR, LOOKING ONLINE FOR A HOTEL (I WAS PLANNING ON DRIVING UP TO CANADA AND AN NOW STUCK IN OHIO), AND HAVE TO PAY $3,000 TO GET THIS FIXED BECAUSE OF THE AGE OF THE CAR. NEVERMIND THAT IT IS A KNOWN ISSUE!!

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.

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.
