I TOOK MY VEHICLE INTO SIERRA NISSAN, BIRMINGHAM ALABAMA ON 11-11-2011 FOR SERVICE DUE TO EXPERIENCING PROBLEMS. I WAS TOLD THAT THE COOLER FROM THE RADIATOR HAD LEAKED INTO THE TRANSMISSION AND THE TRANSMISSION FLUID LEAKED INTO THE RADIATOR AND BOTH NEEDED TO BE REPLACED. I WAS NOT TOLD BY ANYONE IN THE SERVICE DEPT OF THE RADIATOR ASSEMBLY ISSUE WITH NISSAN 2005-2010 FRONTIER, PATHFINDER, AND XTERRA. I FOUND THIS INFORMATION BY SURFING NISSAN WEBSITE. I DID THIS BECAUSE I WAS BEING TOLD BY EVERY REPAIR SHOP IN THE SURROUNDING AREA OF BIRMINGHAM THAT NISSAN IS WELL AWARE OF THIS ISSUE AND SHOULD DO A RECALL ON IT. I CALLED NISSAN CONSUMER AFFAIRS ON 1-10-2011 ABOUT THE INFORMATION THAT I DISCOVERED. I WAS TOLD THAT I NEEDED TO TAKE MY VEHICLE BACK TO THE NISSAN DEALERSHIP TO ACCESS THE REPAIRS A BECAUSE IT HAD BEEN OVER 30 DAYS SINCE I TOOK MY VEHICLE INTO A NISSAN DEALERSHIP FOR SERVICE. THEN, MY REQUEST WOULD BE REVIEWED BY CONSUMER AFFAIRS TO SEE IF NISSAN WOULD PAY FOR THE REPAIRS. I EXPLAINED TO THE REPRESENTATIVE THAT I DID NOT HAVE ANOTHER $100 TO HAVE THE SERVICE DEPT TO TELL ME THE SAME THING AGAIN. I GOT AN EMAIL 2 WEEKS AGO FROM NISSAN FOR A SURVEY AND NEVER HEARD ANYTHING BACK. WHEN I PURCHASED THIS VEHICLE IN 2008 I ALSO PURCHASED THE EXTENDED WARRANTY WITH NISSAN, WHICH NOW IS EXPIRED. I COULD NOT AFFORD TO PAY $5,695 FOR REPAIRS SO I WENT OUT AND FOUND A LICENSE TRANSMISSION SHOP THAT COULD DO IT AT A LESSER AMOUNT. THE TRANSMISSION SHOP TOLD ME THAT THEY ARE HAVING A DIFFICULT TIME WITH NISSAN AND ORDERING PARTS FOR THE TRANSMISSION BECAUSE NISSAN CAN NOT PRODUCE THE PARTS FAST ENOUGH DUE TO THE HIGH DEMAND FOR REPAIRS FOR THIS ISSUE. EVEN THOUGH, I HAVE 114,700 MILES ON MY VEHICLE I AM ASKING NISSAN TO DO THE HONORABLE THING AND STAND BEHIND THEIR COMPANY VISION "ENRICHING PEOPLE LIVES", BY PAYING FOR THE REPAIRS OF THIS VEHICLE. *TR

2005 NISSAN PATHFINDER TRANSMISSION PROBLEMS TOOK MY 2005 NISSAN PATHFINDER TO THE DEALER FOR TRANSMISSION REPAIR. THE NISSAN ADVISOR AND I NOTICED TRANSMISSION FLUID IN MULTIPLE PLACES. COOLANT CONTAINER WAS MUDDY WITH TRANSMISSION FLUID. VEHICLE HAD JUST ENOUGH MILES BELOW THE 80,000 MILES. HOPEFULLY THE NISSAN COMPANY WILL COVER THE REPAIRS. TECHNICIAN SAID THE 80,000 MILES WARRANTY WILL BE GOOD UNTIL SOMETIME IN THE YEAR 2013. I WAS IN THE FREEWAY DRIVING AND THE TRANSMISSION STARTED TO SLIP. THIS IS VERY DANGEROUS BECAUSE I COULD OF BEEN IN AN ACCIDENT IF I WAS MAKING A LEFT TURN IN THE HIGHWAY AND THE OPPOSITE DRIVER COULD OF HIT THE TRUCK IN THE PASSENGER SIDE. THE NISSAN ADVISOR TOLD ME THIS PROBLEM IS HAPPENING TO MANY VEHICLES FROM THE YEARS OF 2005 TO 2007. JUST TODAY HE REGISTERED 5 VEHICLES FOR REPAIRS. THE MAJORITY HAD 83,000 TO 91,000, SO THE WARRANTY WILL NOT COVER. BE VERY CAREFUL WITH THESE TYPE OF VEHICLES. TRANSMISSION REPAIR FOR A 2005 NISSAN PATHFINDER RUNS FROM $4,000 TO $6,000 PLUS OTHER PARTS. NISSAN SHOULD EXTEND THE WARRANTY TO AT LEAST 100,000 MILES AND REPAIR THE RADIATOR PROBLEM. THE NISSAN ADVISOR INFORMED ME THAT THE RADIATOR GETS DAMAGED AND ANTIFREEZE MIXES INSIDE TRANSMISSION,"THIS DAMAGES THE TRANSMISSION AND MANY OTHER PARTS DUE TO THE EXCESSIVE LEAKING AND SPLASHING OF THE TRANSMISSION FLUID." *TR

8-9-2010 I BEGAN HAVING DIFFICULTY GETTING MY CAR TO SHIFT INTO REVERSE. WITHIN 2 WEEKS, WHILE DRIVING DOWN A CROWDED HIGHWAY, MY CAR WOULDN'T SHIFT FROM 3RD TO 4TH, AND I COULD SMELL SOMETHING BURNING. WHEN I FINALLY FOUND A SPOT TO PULL OVER AND PARK, A LARGE PUDDLE OF FLUID LEAKED ALL OVER THE GROUND. I WAS ALONE, IN AN AREA I DIDN'T KNOW, AND NEARLY GOT REAR-ENDED SEVERAL TIMES WHEN IT WOULDN'T SHIFT GEARS. I TOOK IT TO SEVERAL SHOPS, AND THE TRANSMISSIONS WAS RUINED. IT WOULD HAVE TO BE REBUILT OR REPLACED, BOTH TOTALING THOUSANDS OF $ I DON'T HAVE. I BORROWED MONEY TO HAVE IT REBUILT. WITHIN 2 WEEKS, I STARTED HAVING THE SAME ISSUES. WHEN I TOOK IT BACK TO THE SHOP, THE TECHNICIAN SAID RADIATOR COOLANT HAD LEAKED INTO THE TRANSMISSION AND IT WOULD HAVE TO BE REBUILT OR REPLACED AGAIN. AFTER LOOKING ONLINE, I SEE HUNDREDS OF COMPLAINTS FOR THE EXACT SAME ISSUE. FOR THE FUEL SYSTEM, APPROXIMATELY 5/2010, THE FUEL GAUGE WILL DROP TO EMPTY, EVEN THOUGH THERE WILL STILL BE FUEL IN THE TANK. SOMETIMES IT WILL STICK TO MID-FULL WHEN THERE IS NO FUEL. ADAPTIVE EQUIPMENT, WHEN I START THE VEHICLE AND TRY TO WARM IT UP, IT WILL ONLY BLOW COLD AIR, NEVER WARM NO MATTER HOW LONG IT RUNS. *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.

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.
