IN DEC. '09, NOTICED REAR END VIBRATION AND CLINKING SOUND. THOUGHT IT MIGHT BE TRANSMISSION PROBLEM. PURE COINCIDENCE-BROUGHT IT TO DEALER FOR COOLANT FLUSH WAS TOLD THAT THERE WAS TRANS FLUID IN MY RADIATOR. CALLED MY TRANS REPAIR PEOPLE (NOT NISSAN). THEY WERE AWARE OF PROBLEM. TOLD ME THAT RADIATORS IN PATHFINDER 2005'S WERE DEFECTIVE. COOLANT LEAKED THROUGH ONE OF RADIATOR TRANS COOLERS, INTO TRANS. AND TRANS FLUID LEAKED BACK INTO RADIATOR, RENDERING BOTH IRREPARABLE. NEEDED NEW TRANS AND RADIATOR. TOLD DEALER AND NISSAN. THROUGH SEVERAL PHONE CALLS/NEGOTIATIONS,, NISSAN AGREED TO DO THE $5,000-7000 REPAIR FOR DEALER LABOR CHARGE OF $450. TOLD ME I WOULD GET MONEY BACK IF THERE WAS A RECALL. DEALER DID REPAIR. THE PROBLEM IS ALSO A SAFETY ISSUE, BECAUSE RADIATOR AND/OR TRANS CAN FAIL WHILE ON THE ROAD. COUNTLESS PATHFINDER OWNERS HAVE REPORTED THE PROBLEM TO NO AVAIL. NISSAN GETTING AWAY WITH A MAJOR DEFECT THAT COULD PROVE DANGEROUS. *TR

THE FUEL GAUGE IS NO LONGER WORKING. THE COMPUTER IN THE VEHICLE CANNOT READ IF ANY FUEL IS IN THE TANK IN TURN LIGHTING THE "SERVICE ENGINE SOON" LIGHT. THIS IS A GREAT CONCERN AS THE DRIVE DOESN'T KNOW HOW MUCH FUEL IS IN THE VEHICLE WHICH MAY CAUSE SERIOUS ACCIDENTS AS A RESULT OF A STALLED VEHICLE IN TRAFFIC. *TR

FUEL SENDER GAUGE ON MY 2005 NISSAN PATHFINDER IS FAILING OR HAS FAILED. WILL CONSISTENTLY FLASH DASHES OR REPORT "0" FOR THE DISTANCE TO EMPTY INDICATOR AND THE FUEL GAUGE IS NOW RESPONDING SIMILARLY. THERE HAS BEEN NO DAMAGE TO PROPERTY OR INJURY AS OF YET, BUT I AM APPALLED THAT NISSAN HAS THE 2005 ARMADA (SIMILAR DESIGN) AND THE 2006 PATHFINDER LISTED FOR THE RECALL, BUT CLAIMS THE PATHFINDER IS NOT COVERED BY THIS, WHEN A QUICK SEARCH OF FORUMS WILL OFFER UP OVERWHELMING EVIDENCE THAT THIS IS A PROBLEM FOR NUMEROUS PARTS OF THE PRODUCT LINE AND COULD EASILY RESULT IN THE CAR SHUTTING DOWN DUE TO FAULTY INFORMATION OR RUNNING OUT OF FUEL DUE TO INACCURATE READINGS. TO MAKE MATTERS WORSE FOR OWNERS THE REPAIR FOR THIS RUNS UPWARD OF $600 FOR AN ADMITTED FAULTY PART. CAN THE DOT AT LEAST LOOK INTO THIS AND CONSIDER RECTIFYING THIS SITUATION? I AM HAVING A HARD TIME BELIEVING THAT A COMPANY COULD JUST OVERLOOK THIS PROBLEM AND SIMPLY GET AWAY WITH IT. PLEASE HELP US WHO ARE HAVING A HARD ENOUGH TIME MAKING ENDS MEET EVERY MONTH SINCE THIS ECONOMIC DOWNTURN BEGAN AND ARE LOOKING AT UNEXPECTED VEHICLE FAILURES THAT ARE BLATANTLY A MANUFACTURER'S DEFECT (EVEN ADMITTED TO) BUT NOT COVERED BY SOME WEIRD ECONOMIC CHOICE. IF I'D THOUGHT I'D BE GOING THROUGH THIS, I WOULD'VE BOUGHT BOTH SMALLER AND FROM ANOTHER MANUFACTURER. YOU CAN BET THAT CURRENTLY I WILL NOT BUY ANOTHER NISSAN AGAIN, REGARDLESS OF HOW MANY AMERICANS THEY EMPLOY. *TR

DEALER ADVISED TORQUE CONVERTER WAS BAD..SECOND OPINION MECHANIC ADVISED RADIATOR LEAKED INTO TRANS, AND TRANS FLUID LEAKED INTO COOLANT. COOLANT DESTROYED TRANSMISSION. LEARNED THIS HAS BEEN A ONGOING PROBLEM WITH PATHFINDERS FOR YEARS, THERE IS A WELD INSIDE THE RADIATOR THAT FAILS AND THE TWO LIQUIDS TRANSFERS. WHY WOULD THE COMPANY DESIGN A RADIATOR THAT HAS TWO LIQUIDS INSIDE THAT CAN CONTAMINATE EACH OTHER. *TR

VEHICLE HESITATES DURING OVERDRIVE AT SPEED OF @ 40-50MPH. VIBRATION OCCURS AND GEARS DO NOT PROPERLY ENGAGE. FAILURE IS DUE TO DEFECTIVE RADIATOR LEAKING FLUIDS INTO TRANSMISSION.

1) THE TRANSMISSION COMPLETELY FAILED WITH NO PREVIOUS WARNING/INDICATION ON A 2005 NISSAN PATHFINDER AROUND THE 82K MILE MARK. I JUST BOUGHT THE CAR USED LESS THAN 1 MONTH AND 1K MILES PREVIOUSLY. I WAS IN THE PROCESS OF MERGING ONTO AN EXPRESSWAY AT THE TIME AND FOUND MYSELF UNABLE TO FULLY ACCELERATE. I BASICALLY COASTED IT OFF THE ROAD AT THIS POINT. ALTHOUGH AN ACCIDENT WAS AVERTED ONE COULD HAVE EASILY OCCURRED. 2) FROM WHAT I WAS TOLD, THE TRANSMISSION SEIZED UP ENTIRELY, AND ALL OF THE FLUIDS DRAINED OUT ENTIRELY. IT ONLY HAPPENED ONCE, HOWEVER IT CAUSED MY VEHICLE TO INSTANTLY BE "DEAD IN THE WATER". 3) THE CAR HAD TO BE TOWED TO THE DEALERSHIP TO HAVE THE U-JOINT AND THE TRANSMISSION REPLACED (NEW) FOR A ROUGHLY 7200 TOTAL PRICE TAG THAT FORTUNATELY FOR ME THE EXTENDED WARRANTY COMPANY ULTIMATELY COVERED (MINUS THE DEDUCTIBLE) AFTER MUCH BACK AND FORTH / INSPECTIONS OVER 6 WEEKS. *TR

I TOOK THE CAR INTO THE DEALERSHIP, THEY TOLD ME THAT I NEEDED TO GET A NEW RADIATOR AND TRANSMISSION B/C MY RADIATOR FLUID WAS LEAKING INTO MY TRANSMISSION. THEY QUOTED ME AT $6000. I THEN TOOK MY CAR TO GET A NEW RADIATOR AND TRANSMISSION FLUSH, IT HELPED A LITTLE. MY CAR FINALLY GAVE OUT 2 WEEKS AGO. WHILE DRIVING DOWN A SIDE STREET, THENALL OF A SUDDEN THE TRANSMISSION WOULDN'T SWITCH GEARS. I TRIED PRESSING THE GAS TO GO AND THE TRANSMISSION WOULD NOT GO. THE CAR WAS STILL RUNNING, HOWEVER I COULDN'T GRAB ANY GEARS TO GO. I GOT IT TOWED TO A TRANSMISSION SHOP, THEY TOLD ME THAT MY RADIATOR FLUID IS LEAKING INTO MY TRANSMISSION WHICH MADE MY TRANSMISSION LOCK UP. THEY TOOK MY TRANSMISSION APART TO LOOK AT PARTS AND APPARENTLY EVERYTHING IS RUSTY TOGETHER, NOT TO MENTION THE "COMPUTER" IN THE TRANSMISSION IS FRIED. YOU WOULD THINK THAT NISSAN WOULD RECOGNIZE AN ISSUE WHEN THEY SEE THAT SAME PART IS ON BACKORDER B/C I AM WAITING ON A PART. WHILE READING OTHERS WITH THE SAME ISSUE, SOME HAVE BEEN ON THE HIGHWAY AND THE TRANSMISSION WENT OUT. THIS IS DEFINITELY A SAFETY ISSUE SEEING AS IF DRIVING AT HIGH SPEEDS YOU COULD POSSIBLY GET REAR ENDED BADLY. I ALMOST GOT REARENDED WHILE ONLY GOING 45MPH. *TR
