I OWN A NISSAN PATHFINDER 2008. THE PROBLEM WAS NOTICED WHEN THE VEHICLE'S RADIATOR BEGAN TO RUN HOT. WE TOOK IT TO A REPAIR SHOP AND WAS TOLD THAT THE COOLANT WAS MIXING WITH THE TRANSMISSION FLUID. WE REPLACED THE RADIATOR IN HOPES THAT THE DAMAGE HAD NOT EXTENDED TO THE TRANSMISSION. WHILE OUT OF TOWN ON A TRIP, THE TRANSMISSION WENT OUT IN THE PATHFINDER. THE TRUCK WAS TRANSPORTED TO THE LOCAL DEALER WHO ADVISED THAT THE TRANSMISSION WAS GONE, AND IT WOULD REQUIRE REPLACING. I HAVE PREVIOUSLY CALLED NISSAN AND WAS ADVISED THAT THERE WAS SOME TYPE OF RECALL, BUT MY VEHICLE HAD TOO MANY MILES. THE DEFECT IS A MANUFACTURER'S DEFECT, NOT ONE OF MY OWN DOING. NISSAN WILL NOT STAND BEHIND THEIR VEHICLES. PLEASE INVESTIGATE THIS MATTER. THERE ARE ALOT OF PEOPLE DEALING WITH THE SAME THING. *TR

CAR SUDDENLY STALLS AND WILL NOT DRIVE IN "REVERSE". PER MECHANIC, THERE IS A CRACK IN THE RADIATOR WHICH IS ALLOWING COOLANT FROM THE RADIATOR TO ENTER INTO THE TRANSMISSION. APPARENTLY, THERE HAS BEEN A PREVIOUS LAWSUIT AGAINST NISSAN FOR THIS SAME ISSUE. A RECALL ON THESE "CRACKED RADIATORS" MUST BE ISSUED IMMEDIATELY. *TR

I WAS PULLING OUT INTO ONCOMING TRAFFIC WHEN MY CAR LOST POWER AND WOULDN'T MOVE . THE TRANSMISSION BUCKED AND KICKED BACK IN AND I WAS ABLE TO DRIVE . I BROUGHT VEHICLE TO MY MECHANIC THE NEXT DAY AND HE FOUND THE RADIATOR COOLANT WAS IN MY TRANSMISSION . AFTER FURTHER LOOK HE FOUND COOLANT LINE WAS WERE LEAKING INTO TRANSMISSION WHICH HAD CAUSED FAILURE . MY VEHICLE IS PAST THE NISSAN WARRANTY BECAUSE OF MILES BUT THIS IS A CONTINUING PROBLEM ON ALL NISSAN SUV'S MADE IN THESE TIME FRAMES . THIS ISN'T A WARRANTY ISSUE, IT IS A RECALL ISSUE . NISSAN NEEDS TO STAND UP FOR THEIR MISTAKE AND SUBMIT A RECALL. *TR

IN FEBRUARY OF 2013, MY 2008 NISSAN PATHFINDER STARTED VIBRATING AND SHAKING WHILE DRIVING AT A LOW SPEED OF 40 MPH. AT FIRST I THOUGHT IT WAS ROUGH ROAD BUT IT CONTINUED AND GOT WORSE. THE SUV SLIPS ALOT AND IT JERKS FORWARD EVEN WHEN I BRAKE. IT HAS BECOME SCARY TO DRIVE, BUT IT IS OUR FAMILY'S ONLY CAR. I NEED SOMETHING SAFE TO TRANSPORT MY YOUNG KIDS IN AND THIS DEFINITELY IS NOT A SAFE CAR. I TOOK THE SUV TO THE DEALERSHIP AND THEY SAID THAT THE TRANSMISSION IS BAD DO TO A FAULTY RADIATOR AND THAT BOTH NEEDED TO BE REPLACED BUT SINCE I WAS BARELY OVER 80K MILES I WOULD HAVE TO PAY $2500. I DID RESEARCH AND FOUND THAT THIS IS A COMMON PROBLEM ON NISSANS PART AND THAT MANY PEOPLE HAVE BEEN AFFECTED BY THIS ISSUE. I BOUGHT THE SUV IN 2010 AS A CERTIFIED PRE-OWNED THAT ALREADY HAD 48K MILES ON IT. I ALSO HAVE A 84 MONTH/100K MILES LIMITED WARRANTY ON THE CAR THAT COVERS THE TRANSMISSION, BUT I WAS TOLD THAT THIS WARRANTY WOULD NOT COVER MY TRANSMISSION SINCE MY TRANSMISSION WAS DAMAGED BY NISSAN'S FAULTY RADIATOR. THIS MAKES NO SENSE AT ALL. NISSAN IS THE WORST! *TR

MY 2008 NISSAN PATHFINDER HAS A RADIATOR THAT FAILED CAUSING ENGINE COOLANT TO MIX WITH THE AUTOMATIC TRANSMISSION FLUID THUS CAUSING A TOTAL FAILURE OF MY TRANSMISSION. IN RESEARCHING AFTER THE FAILURE I HAVE FOUND THIS IS A VERY COMMON PROBLEM WITH NISSAN PATHFINDERS, FRONTIERS, AND XTERRAS FROM 2005-2008. IT IS TO THE POINT WHERE PEOPLE HAVE TAKEN THE TRANSMISSION LINE OUT OF THE COOLANT SYSTEM LOOP PRIOR TO THE RADIATOR FAILING IN ATTEMPT TO SAVE THE TRANSMISSION FROM THE INEVITABLE FAILURE. THESE RADIATORS NEED TO BE RECALLED TO PREVENT ANOTHER TRANSMISSION FROM TOTAL FAILURE AND THUS PREVENT SERIOUS ACCIDENTS RESULTING IN INJURY OR DEATH IN THE FUTURE. THIS IS A SAFETY CONCERN! IN MY INSTANCE WHILE DRIVING MY WIFE AND MY 7 DAY OLD FIRST BORN SON TO HIS DOCTORS APPOINTMENT MY NISSAN PATHFINDER BEGAN TO HESITATE AND SLIP, THEN CATCH, AND SLIP, AND LOCK UP, AND JERK, AND THEN ONLY SLIP. I WAS FORCED TO PUSH MY VEHICLE A DISTANCE WHILE VEHICLES PROCEEDED TO PASS ME AT A HIGH RATE OF SPEED. ALL THE WHILE MY WIFE AND 7 DAY OLD INFANT INSIDE. I THEN NEEDED TO HAVE MY CAR TOWED TO THE DEALERSHIP. AFTER CALLING THE NISSAN DEALERSHIP I WAS TOLD THAT IS FAIRLY COMMON AND THEY WERE NOT SURPRISED. 2005-2008 NISSAN PATHFINDERS, XTERRAS, AND FRONTIERS HAVE FAULTY RADIATORS THAT ARE CAUSING CATASTROPHIC FAILURE TO THE TRANSMISSION AND ARE EXTREMELY UNSAFE FOR THE PASSENGERS OF THESE VEHICLES. DOES SOMEONE HAVE TO DIE BEFORE NISSAN ADMITS TO AND FIXES THIS AVOIDABLE PROBLEM? THIS IS VERY COMMON KNOWLEDGE FOR ALL TRANSMISSION REPAIR SHOPS AS WELL AS NISSAN DEALERSHIPS. *TR
