COOLANT MIXING IN THE TRANSMISSION SYSTEM. SOME ISSUES WITH SLIPPING AT FIRST, MECHANICS COULDN'T FIGURE IT OUT. SAID THEY WOULD HAVE TO TAKE APART THE TRANSMISSION TO FIGURE IT OUT SINCE THERE WERE NO CODES BEING TRIPPED. THEN THE SLIP GOT WORSE AND THEY HAPPENED TO DISCOVER HOW BAD THE FLUID LOOKED BY THE U-JOINT UNDERNEATH THE CAR. IT WAS ONLY THEN THAT THEY DISCOVERED THAT THE PROBLEM COULD HAVE BEEN RELATED TO THE RADIATOR COOLANT LEAK. THEY PROCEEDED TO FIX THE RADIATOR AND RELATED COMPONENTS AND FLUSHED THE SYSTEM SEVERAL TIMES ($726.81) ONLY 2 MONTHS LATER THE TRANSMISSION WAS ACTING UP AGAIN AND ALMOST FAILED ON THE FREEWAY, STUTTERING THE ENGINE AND SMOKING A BIT. FORTUNATELY, WE WHERE ABLE TO LIMP THE VEHICLE HOME AND GET IT TO THE MECHANIC THE NEXT DAY. VEHICLE WAS AT THE SHOP FOR 3 WEEKS, THEN THE MECHANIC THOUGHT HE HAD IT FIXED. WE DROVE THE CAR ABOUT 5 MILES DOWN THE ROAD, THE VEHICLE STARTED TO STUTTER AND SLIP AGAIN AND THE CHECK ENGINE LIGHT CAME ON AGAIN. WE RETURNED THE VEHICLE TO THE SHOP, THEY CHECKED THE CODES AND DETERMINED THAT THE TRANSMISSION WOULD NEED TO BE REPLACED. THIS IS RIDICULOUS...... WHEN YOU PAY THIS MUCH MONEY FOR A VEHICLE, THERE IS NO REASON WHY A TRANSMISSION SHOULD FAIL IN 94,000 MILES. I CAN'T BELIEVE ALL THE HORROR STORIES I HAVE READ ON THE INTERNET RELATED TO THIS NISSAN TRANSMISSION ISSUE. I FEEL A SICK TO MY STOMACH RIGHT NOW JUST THINKING ABOUT THE FINANCIAL IMPACT THAT THIS HAS AND WILL CAUSE TO MY FAMILY. THERE IS ABSOLUTELY NO REASON THAT NISSAN SHOULDN'T BE RESPONSIBLE FOR THIS CATASTROPHE. ESPECIALLY AFTER THEY HAVE IDENTIFIED THAT THIS IS A KNOWN ISSUE. *TR

WHILE DRIVING UP TO SPEED AT 55 MPH THE TRANSMISSION STARTED MAKING A RUMBLING NOISE LIKE IF DRIVING OVER ROUGH PAVEMENT. WHEN THE TRANSMISSION SHIFTS TO IT OVER DRIVE GEAR IT STARTS RUMBLING. RADIATOR FLUID IS CONTAMINATING THE AUTOMATIC TRANSMISSION. *TR

THE VEHICLE EXPERIENCED LOSS OF POWER WHILE DRIVING AT 60MPH IN THE FREEWAY. AFTER A FEW SIMILAR INCIDENTS I TOOK THE VEHICLE TO THE DEALER FOR A RECALL THAT DESCRIBED A SIMILAR ISSUE, A RELAY WAS CHANGED.. THE VEHICLE CONTINUE EXPERIENCING THE JERKING UNTIL A FEW WEEKS AGO THAT IT LOOK LIKE TRANSMISSION FLUID LEAKED IN THE DRIVEWAY. I TOOK THE VEHICLE TO THE NEAREST SHOP FOR A CHECK UP. APPARENTLY COOLANT WAS LEAKED INTO THE TRANSMISSION. WE TOOK THE VEHICLE TO NISSAN WE THE HOPED THAT THEY WOULD HONOR A WARRANTY EXTENSION, THEY ASKED AS TO PAY FOR A TEST TO CONFIRM WHAT WE ALREADY NEW. WE WERE TOLD THAT WE NEEDED TO CONTACT NISSAN'S 800 NUMBER CORPORATE OFFICE CAUSE THERE WAS A CHANCE THAT THEY MIGHT WANT TO EXTEND THE WARRANTY. I UNDERSTAND THAT THEY EXTENDED THE TRANSMISSION WARRANTY TO 80K DUE TO THIS COMMON ISSUE. THEY TOTALLY DENIED THE EXTENSION CAUSE MY VEHICLE HAD 107,000 MILES. THANKS GOD THAT WE HAVE NOT HAD AN ACCIDENT AS A RESULT OF THIS ISSUE. NOW WE HAVE TO INCUR THE EXPENSIVE COST OF REPLACING THE RADIATOR AND TRANSMISSION. THIS FACTORY DEFECT SHOULD BE PAID BY NISSAN AND WE NEED AN INVESTIGATION INTO THIS COMMON ISSUE. PLEASE LET'S NOT WAIT UNTIL A FATALITY OCCURS FOR YOUR ORGANIZATION TO INITIATE IT. *TR

COOLANT LEAKING INTO TRANSMISSION. WELL-KNOWN NISSAN ISSUE. VEHICLE STARTED RUMBLING INTERMITTENTLY GOING BETWEEN 4TH AND 5TH GEAR AROUND 40 AND 60 MPH. THE RUMBLING WILL LAST BETWEEN 2 AND 5 SECONDS UNTIL THE ACCELERATOR IS DEPRESSED HARD ENOUGH TO FORCE THE VEHICLE TO DOWNSHIFT WHICH RESULTS IN A LOUD BANGING NOISE AND A JERK. ALSO NOTICED WHAT LOOKS LIKE CURDLED MILK ALL AROUND THE RADIATOR CAP. I HAVE AN APPOINTMENT WITH THE DEALERSHIP, NISSAN OF SACO, ON 08/28/2012 AND AM ALMOST CERTAIN THEY WILL TRY AND GET OUT OF COVERING THIS UNDER THE "LIFETIME POWERTRAIN WARRANTY". *TR

I WAS DRIVING MY 2005 NISSAN PATHFINDER ON AUGUST 11TH, 2012 WITH MY ENTIRE FAMILY INSIDE THE VEHICLE. WE WERE ROLLING IN TRAFFIC AT ABOUT 40 TO45 MPH WHEN THE VEHICLE ALL OF A SUDDEN STOPPED ACCELERATING. I WAS ABLE TO SAFELY PULL OVER TO THE SIDE OF THE ROAD. WHILE INSIDE THE VEHICLE TRYING TO FIGURE OUT WHAT WAS GOING ON, A PASSERBY TOLD ME HE SAW A FIRE UNDER THE VEHICLE. I IMMEDIATELY GOT MY FAMILY OUT AND CALLED 911 TO HAVE THE FIRE DEPARTMENT COME OUT AND LOOK AT IT. BY THE TIME THE FIRE DEPARTMENT GOT ON SCENE, THE FIRE HAD DIED OUT. I HAD MY VEHICLE TOWED TO A TRANSMISSION SHOP BECAUSE A FIREMAN SUGGESTED IT WAS AN ISSUE WITH MY TRANSMISSION. THE REPAIR SHOP TOLD ME A COOLER UNDER THE RADIATOR BUSTED CAUSING COOLANT TO GET INSIDE MY TRANSMISSION, WHICH CAUSED TRANSMISSION FLUID TO GET ON MY CATALYTIC CONVERTER WHICH STARTED THE FIRE. THEY QUOTED ME $4900 IN REPAIRS, TELLING ME I NEEDED TO HAVE MY TRANSMISSION AND RADIATOR REPLACED. I AM EXTREMELY UPSET BECAUSE FOR ONE, MY ENTIRE FAMILY COULD HAVE BEEN KILLED OR INJURED INCLUDING MYSELF, MY WIFE, AND 3 SONS AGES 3 9 & 13. SECONDLY, I'VE ONLY HAD THE CAR FOR 5 AND HALF MONTHS AT THE TIME AND STILL MAKING PAYMENTS ON IT. IN FACT, I OWE JUST ABOUT $1000 MORE ON THE LOAN FOR THE VEHICLE VERSES THE COST OF REPAIRS. SO NOW I AM LEFT WITH NO VEHICLE, NO WAY TO TAKE MY KIDS TO SCHOOL, AND THE UGLY FACT THAT I AM NOT THE ONLY PERSON WHO HAS EXPERIENCED THE SAME ISSUE WITH THIS VEHICLE. AFTER A LITTLE RESEARCH VIA THE INTERNET, IT LOOKS LIKE THIS IS A NORMAL OCCURRENCE WITH THIS MODEL. IN CLOSING, I AM JUST LOOKING FOR ANY SORT OF HELP I CAN GET TO HELP GIVE ME AND MY FAMILY SOME RELIEF OF THIS TRAGIC AND DANGEROUS SITUATION. THINGS COULD HAVE ENDED UP MUCH WORSE AND I REALLY FEEL THIS VEHICLE PRESENTS A SAFETY HAZARD TO OUR ROADWAYS. *TR

MY 2005 PATHFINDER WAS RUNNING FINE UNTIL IT STARTED DEVELOPING A CASE OF THERMOSTAT FLUCTUATION; IT WOULD ALMOST GO INTO THE RED AND THEN DROP ALL THE WAY BACK DOWN TO THE NORMAL LEVEL. I TOOK IT TO PRECISION TUNE AND THEY REPLACED THE RADIATOR HOSE ASSEMBLY. A FEW WEEKS AFTER THAT, THE TRANNY STARTED SLIPPING. AS I HAD ALREADY READ FROM OTHER CONSUMERS, I KNEW WHAT WAS HAPPENING TO MY TRUCK, AND BECAUSE THE TRUCK ALREADY HAD 120K + MILES ON IT, I KNEW WHAT NISSAN WOULD LIKELY SAY. SURE ENOUGH, ONE AFTERNOON, I GOT IN THE TRUCK AND IT WOULDN'T ACCELERATE FORWARD. I IMMEDIATELY HAD IT TOWED TO NISSAN IN APRIL AND BEGAN THE FIGHT TO GET IT FIXED; THEY QUOTED ME $5100 TO REPLACE THE TRANNY AND RADIATOR DUE TO COOLANT LEAKING INTO THE TRANSMISSION CASE AND TRANSMISSION FLUID LEAKING INTO THE RADIATOR. I CONTACTED THEIR CONSUMER AFFAIRS, AND NOT ONLY DID THEY TELL ME THEY WOULDN'T COVER IT, BUT REFERRED ME TO THE BBB (A VERY BRAZEN MOVE IN MY MIND, TO HAVE A COMPANY REFER YOU TO THEM ABOUT THEM). THEY ALREADY KNEW THE BBB WOULDN'T HELP BECAUSE IT WAS OUTSIDE OF THE WARRANTY. NEARLY FOUR MONTHS LATER, IT STILL SITS AT THE DEALER, BECAUSE I CAN'T AFFORD TO PAY THE REPAIR COST (I STILL OWE FOR TWO YEARS ON THE VEHICLE), AND NISSAN REFUSES TO FIX IT, ALTHOUGH THEY KNOW THE PROBLEM EXISTS. SOMEONE HAS TO DIE, I GUESS, BEFORE THEY PULL THEIR VEHICLES OFF THE ROAD AND FIX THE PROBLEM. *TR
