I BOUGHT THIS VEHICLE IN JUNE 2011 FROM BENSON NISSAN IN SPARTANBURG, SC. I HAD NO IDEA ABOUT THE RADIATOR/TRANSMISSION PROBLEMS THESE VEHICLES WERE HAVING &OF COURSE IT WASN'T MENTIONED IN THE SALE. IT WAS ALREADY SLIGHTLY PAST THE 80,000 MILE WARRANTY (THE PREVIOUS OWNER WAS OBVIOUSLY AWARE OF PROBLEMS) FOR THE RADIATOR. LESS THAN 2 WEEKS AFTER PURCHASE I TOLD THE SALES PERSON &A MECHANIC THAT THE CAR WAS JERKING AT AROUND 60 MPH WHEN CHANGING GEARS. THE MECHANIC BLAMED ?BAD GAS? & ?ETHANOL? & ASSURED ME IT WASN'T THE TRANSMISSION. LESS THAN A MONTH LATER, I TOOK IT BACK TO THE DEALER?S &TOLD THEM THE CAR WAS STILL JERKING AT 60MPH &ASKED THEM ABOUT THE TRANSMISSION. THEY AGAIN TOLD ME THERE WAS NOT A PROBLEM WITH THE TRANSMISSION. THE CAR CONTINUED TO SHAKE WORSE WHEN SHIFTING &I CONTINUED TO CALL NISSAN &COMPLAIN. THE SALES PERSON EVEN OFFERED TO TRADE THE CAR IN FOR ME, BUT RENEGED WHEN HIS MANAGER DECLINED BECAUSE I ?GOT TOO GOOD OF A DEAL ON THAT CAR &(THEY) COULDN'T TRADE IT BACK.? THE SHAKING BEGAN TO GET WORSE &SPREAD TO LOWER GEARS &I ACCEPTED THE FACT THAT I WAS SOLD A LEMON. THROUGH ALL THIS, NO ONE AT THE NISSAN DEALERSHIP MENTIONED THE TRANSMISSION OR RADIATOR PROBLEM. I FOUND OUT ABOUT IT ONLY AFTER I BEGAN TO RESEARCH HOW TO REPAIR IT MYSELF &BY THEN ALL I COULD DO WAS PRAY. BARELY ONE YEAR AFTER PURCHASE WHILE ON THE WAY TO MY PARENT?S HOUSE WITH MY CHILD IN THE BACK SEAT, &WHILE ON A BUSY HIGHWAY, THE CAR STUCK IN 2ND GEAR. I BARELY GOT IT TO MY PARENT?S HOUSE &ENDURED A LOT OF ANGRY DRIVERS AROUND ME. IT COST $3700 TO REBUILD THE TRANSMISSION &REPLACE THE RADIATOR THAT LEAKED INTO THE TRANSMISSION &FINALLY AFTER GETTING IT BACK THE JERKING WHILE SHIFTING HAS STOPPED. I SHOULD'VE BEEN INFORMED ABOUT THE TRANSMISSION PROBLEM AT PURCHASE OR AT LEAST AFTER COMPLAINING &NISSAN NEEDS TO MAKE GOOD ON THEIR FAULTY PARTS BEFORE SOMEONE IS REALLY HURT. *TR

AT FIRST INCIDENT, THE TRANSMISSION WOULD START SLIPPING CAUSING A VIBRATION WHILE THE OVERDRIVE WAS ON, THE VIBRATION WOULD GO AWAY WHEN OUT OF OVERDRIVE. THEN THE CAR WOULD STALL WHEN YOU WOULD TRY TO TAKE OFF AT A STOP, THE CAR WOULD NOT MOVE UNTIL YOU WOULD TURN THE CAR OFF AND CRANK IT AGAIN. AS YOU WOULD PULL OUT INTO TRAFFIC THE CAR WOULD NOT GO. THEN EVEN WITH THE CAR OUT OF OVERDRIVE WHILE AT SPEEDS AT 55 MPH OR HIGHER THE TRANSMISSION WOULD NOT WORK, YOU WOULD HAVE TO LET OFF ON THE ACCELERATOR AND WAIT ON THE RPM'S TO DROP AND THEN IT WOULD GO INTO GEAR AGAIN.I TOOK THE CAR TO A LOCAL MECHANIC AND HE ADVISED THE TROUBLE WAS IN A SOLENOID IN THE TRANSMISSION. I TOOK THE CAR TO A TRANSMISSION SHOP, THEY CHECKED THE FLUID AND SAID THERE WAS WATER IN THE TRANSMISSION FLUID, CAUSED BY A COOLANT LEAK FROM INSIDE OF RADIATOR GETTING INTO THE TRANSMISSION LINES CAUSING THE TRANSMISSION TO GO BAD DUE TO COOLANT INTO THE TRANSMISSION. *JS

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 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.

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.
