2007 Nissan Pathfinder ENGINE AND ENGINE COOLING,POWER TRAIN

AT 40 MPH THE VEHICLE WOULD SEEM LIKE IT UPSHIFTED TO A VERY HIGH GEAR AND THEN START TO VIBRATE REAL BAD. WE TOOK IT IN FOR AN ANALYSIS AND THEY TOLD US IMMEDIATELY THAT THE TWO FLUIDS HAD MIXED (TRANS AND COOLANT). *TR

STARTED WITH A CLICKING NOISE THEN STARTED HIGH GEAR STARTED SHIMMING NOW STUCK IN HIGH GEAR & HAVE ANTIFREEZE IN TRANSMISSION. *TR

RADIATOR CRACKED AND MIXING OF COOLANT WITH TRANSMISSION FLUID. RADIATOR NEEDED REPLACED. *TR

I PURCHASED A USED 2007 NISSAN PATHFINDER WITH EXTENDED WARRANTY FOR MY DAUGHTER ON 12/28/13. LAST WEEK THE CHECK ENGINE LIGHT CAME ON. SHE MADE AN APPOINTMENT, ARRIVED EARLY AND 5 HOURS LATER WAS TOLD THAT A SENSOR NEEDED TO BE REPLACED AND SUGGESTED THAT SHE TAKE IT TO A NISSAN DEALER AS THEY HAD EQUIPMENT SPECIFIC TO NISSAN VEHICLES AND HER WARRANTY COVERS THE WORK AT ANY DEALERSHIP. SHE ASKED IF THE VEHICLE WAS SAFE TO DRIVE AND WAS TOLD YES. SHE DROVE TWO MILES TO A NISSAN DEALER SPENT ANOTHER 2 HOURS THERE WHILE THEY RAN THEIR OWN DIAGNOSTIC TESTS. THEY DETERMINED THAT THERE WAS CROSS CONTAMINATION IN THE RADIATOR. NOT ONLY DID HER RADIATOR NEED TO BE REPLACED BUT SO DID HER TRANSMISSION. SHE WAS FURTHER TOLD THAT HER VEHICLE WAS UNSAFE TO DRIVE. THE CALLED THE WARRANTY COMPANY WHO INDICATED THAT THE RADIATOR WASN'T COVERED AND THEREFORE THE TRANSMISSION WASN'T COVERED AS IT WAS CAUSED BY THE RADIATOR. MY DAUGHTER DROVE BACK TO AUTO NATION AGAIN AND ASKED TO SPEAK TO THE GENERAL MANAGER. SHE WAS TOLD HE WASN'T IN AND THE USED CAR SALES MANAGER WOULD SPEAK TO HER. I LEFT WORK AND WENT OVER TO HELP HER. I ALSO ASKED FOR THE GENERAL MANAGER, WAS ASKED WHAT IT WAS ABOUT, I SAID I WOULD PREFER SPEAKING DIRECTLY TO THE GM AND WAS TOLD THE SAME THING AS MY DAUGHTER. THE USED CAR SALES MANAGER RELUCTANTLY AGREED TO REPLACE THE RADIATOR AND FLUSH THE TRANSMISSION TWICE HE INDICATED THAT WOULD SOLVE THE PROBLEM. SHE PICKED UP THE SUV TODAY AND 2 BLOCKS LATER THE CHECK ENGINE LIGHT CAME ON. SHE WENT BACK TO AUTO NATION AND WAS TOLD BY THE USED CAR MANAGER THAT THERE WAS NO WAY HE WAS PAYING $3500 TO REPLACE THE TRANSMISSION. HE TOLD HER TO JUST DRIVE WITH THE CHECK ENGINE LIGHT ON. THIS IS SO WRONG! TO SEND A 22 YEAR OLD OFF IN AN UNSAFE VEHICLE. THIS WAS APPARENTLY A KNOWN ISSUE ON THIS MAKE/MODEL & YEAR. NISSAN EVEN EXTENDED THE WARRANTIES BECAUSE OF THE ISSUE. *TR

VEHICLE HAS NOT BEEN WARMING UP FOR ABOUT 2 WEEKS, NEVER THOUGHT IT WAS ANYTHING SERIOUS, THOUGHT IT WOULD BE A HEATING COIL OR SOMETHING, TOOK IT TO THE DEALER ON 1/3/14 TO GET AN OIL CHANGE AND FOR THEM TO LOOK AT THE PROBLEM AND THE TECHNICIAN CAME BACK AND SAID "OH YOU NEED A TRANSMISSION AND RADIATOR BRING THE CAR BACK ON TUESDAY" LIKE IT WAS SOMETHING COMMON. JUST LOOKED INTO THE COMPLAINTS DID NOT KNOW THIS WAS A COMMON ISSUE WITH THE VEHICLES, NEEDLESS TO SAY THIS WILL BE MY LAST NISSAN. I PURCHASED A EXTENDED WARRANTY WHICH THEY DID ASK ME, HOWEVER I DID NOT KNOW ABOUT THE CLASS ACTION SUIT THAT WOULD HAVE COVERED THE ISSUE UNTIL TODAY 1/8/14. *TR

THE TRANSMISSION BEGAN TO SLIP AND THE RADIATOR FLUID OVERFLOW CANNISTER STARTED TO EXPEL A PURPLE LIQUID. CAR WAS FOUND TO HAVE A CRACKED TRANSMISSION COOLING TUBE IN THE BASE OF THE RADIATOR AND THE ANTIFREEZE HAD MIXED WITH THE TRANSMISSION FLUID. FOUND OUT ON LINE THAT THIS IS A VERY COMMON PROBLEM THAT NISSAN REFUSES TO ACKNOWLEDGE AS A DEFECT. RADIATOR REPLACED AND COOLING SYSTEM FLUSHED ALONG WITH THE REQUIRED TRANSMISSION FLUSHING AND FLUID REPLACEMENT. REPAIRS BECAME VERY EXPENSIVE. ONLY HOPE TRANSMISSION DOESN'T FAIL NEXT. *TR

DISCOVERED A SMALL POOL OF PURPLE LIQUID UNDER FRONT LEFT TIRE OF MY 2007 NISSAN PATHFINDER IN THE GARAGE YESTERDAY. THOUGHT THAT MUST NOT BE GOOD, SO I STARTED DOING SOME RESEARCH ONLINE. BEHOLD, DISCOVERED IT WAS MOST LIKELY A RADIATOR LEAK AND MOST LIKELY LEAKED INTO TRANSMISSION AS WELL. TOOK THE VEHICLE IN TODAY, AND MY CONCERNS WERE CONFIRMED. RADIATOR REPLACEMENT = $800. TRANSMISSION IS WORKING NORMALLY RIGHT NOW, BUT FROM WHAT I CAN TELL THE DAMAGE MAY ALREADY BE DONE AND ITS ONLY A MATTER OF TIME BEFORE CATASTROPHIC TRANSMISSION FAILURE +$4000. THE ISSUE I HAVE WITH THIS WHOLE SITUATION IS NISSAN IS VERY AWARE OF THIS DEFECT, YET DID NOT ISSUE A RECALL. ALL THEY DID WAS EXTEND RADIATOR/TRANSMISSION WARRANTY. THIS WARRANTY DOES NOT APPLY TO MY VEHICLE BEING OVER 100K MILES. ALL NISSAN HAD TO DO WAS ISSUE A RECALL, FIX THE DEFECTIVE RADIATOR (PROBABLY A $500 FIX FOR THEM) INSTEAD, THEY IGNORED IT, AND THE CUSTOMER IS STUCK WITH A $5000 FIX THEY DID NOT EVEN SEE COMING DUE TO THEM NOT NOTIFYING US ABOUT IT. I AM NOT PLEASED. *TR

FLUID LEAKED FROM THE RADIATOR INTO THE TRANSMISSION CAUSING THE TRANSMISSION TO FAIL AND NEED TO BE REPLACED. *TR

TRANSMISSION FAILED, HAD TO REPLACE TRANSMISSION, RADIATOR, MOTHERBOARD FOR COMPUTER INSIDE TRANSMISSION AND HAD TO HAVE LOCKSMITH REPROGRAM SECURITY SYSTEM. *TR

THE COOLANT HAS MIXED UP WITH THE TRANSMISSION FLUID, AND IT IS HAVING PROBLEMS WITH SHIFTING. I DONE SOME RESEARCH ONLINE,AND FOUND OUT THAT THIS A MAJOR ISSUE WITH NISSAN AND THEY ARE NOT WILLING TO FIX THIS ISSUE. IT SAYS THAT THERE A HOSE LEAK ISSUE INTO THE TRANSMISSION. NOW M CAR IS SITTING I N MY DRIVEWAY,DEAD. *TR

I TOOK MY VEHICLE TO THE DEALER FOR A DIAGNOSTIC TEST AND WAS INFORMED THAT THE COOLANT FROM THE RADIATOR WAS LEAKING INTO THE TRANSMISSION AND VICE VERSA. THE SERVICE TECHNICIAN STATED THAT THIS WAS A KNOWN ISSUE WITH MY PARTICULAR MAKE/MODEL VEHICLE. *TR

TRANSMISSION FLUID AND RADIATOR FLUID MIXING SOMEWHERE ALONG THE TRANSMISSION COOLANT ROUTE, CAUSING EXTENSIVE DAMAGE TO THE TRANSMISSION. REQUIRED REPLACEMENT OF BOTH MAJOR ITEMS. *TR

I HAVE A 2007 PATHFINDER WITH 79,541 MILE I HAVE THE SAME PROBLEM ALOT OF PEOPLE ON THIS SITE HAS WITH THE RADIATOR LEAKING INTO THE TRANSMISSION, I TOOK IT TO THE DEALERSHIP FOR A OIL CHANGE AND THEY TOLD ME I HAVE A RADIATOR CREAK THAT LEAKING INTO MY TRANSMISSION AND ITS DANGEROUS TO DRIVE I CANT DRIVE IT AT ALL AND THEY HAVE TO REPLACE THE RADIATOR AND TRANSMISSION BECAUSE IT HAS A MIX OF COLOR LIKE BROWN SO THEY TOLD ME THEY GOING TO ORDER THE PART I ASK THEM FOR A RENTAL CAR BECAUSE I WAS GOING ON VACATION UNTIL MY TRUCK GET FIX THEY SAID THEY WAS GOING TO TRY TO GET ME ONE THAT WAS ON JUNE 30TH AND ON THURSDAY JULY 3TH THEY CALL ME TO PICK UP MY TRUCK BECAUSE THE ENGINE LIGHT DIDN'T COME ON SO THEY WANT ME TO DRIVE IT UNTIL THE ENGINE LIGHT GO ON, REMEMBER A FEW DAYS AGO THEY TOLD ME NOT TO DRIVE IT BECAUSE IT WAS DANGEROUS TO DRIVE I THINK THEY WANT ME TO DRIVE SO IT CAN GO OVER THE 8 YEARS / 80,000 MILE WARRANTY AND PAY A COPAY OF $2,500 AND I REALLY DON'T HAVE THAT MONEY AND I'M STILL PAYING FOR THE TRUCK THEY WANT ME TO TAKE IT OUT OF THEY DEALERSHIP LIKE THAT, I'M SCARE TO DRIVE IT I HAVE A DAUGHTER AND MY DOG I TAKE WITH ME AND SCARE SOMETHING ITS GOING TO HAPPEN TO US PLEASE HELP ME ANYONE THANK YOU *TR

TRANSMISSION WAS SHUTTERING AFTER INSPECTION THERE WAS WATER IN TRANSMISSION FROM LEAKING RADIATOR THAT NISSAN KNEW ABOUT BUT DIDN'T WARN CONSUMERS. *TR

CRACK IN RADIATOR THAT WAS INSTALLED BY NISSAN LEAKED INTO TRANSMISSION. DRIVING DOWN ROAD IT GOT STUCK IN HIGH GEAR. *TR

VEHICLE STRUGGLING TO SHIFT. DIAGNOSIS: TRANSMISSION FLUID LEAKING INTO THE RADIATOR. REPLACED RADIATOR DRAINED AND REPLACED ALL FLUIDS, STILL STRUGGLING TO SHIFT. *TR

THIS VEHICLE WAS BOUGHT FROM DEALER EARLY 2010 WITH AROUND 40,000 MILES. THERE WAS NO KNOWLEDGE OF A MANUFACTURING DESIGN DEFECT INSIDE OF THE RADIATOR. A LEAKAGE DUE TO AN INTERNAL TUBE INSIDE THE RADIATOR CAUSES TRANSMISSION FLUID TO BE CROSS-CONTAMINATED AND BECOME MIXED THEN OVER TIME DESTROYS BOTH THE TRANSMISSION AND RADIATOR. NISSAN MANUFACTURER WON'T HELP WITH REPAIRING THIS PROBLEM. ON TOP OF THAT, THE MILEAGE MAKES ME INELIGIBLE FOR EXTENDED WARRANTY. IT IS 10 YEARS/100,000 MILES WHICH EVER COMES FIRST. HELP ME PLEASE!!!! I DON'T HAVE $10,000 TO PAY FOR THIS REPAIR WHEN ITS NOT MY FAULT. THIS IS A MANUFACTURER DEFECT AND THEY DON'T HAVE AN OFFICIAL RECALL ON THIS PROBLEM BUT AN OUT OF REACH WARRANTY. FAILURE HAPPENS AFTER 100,000 MILES MOSTLY. *TR

VEHICLE BEGAN TO SHAKE AS IF RIDING OVER BUMPS AT APPROX 60-65 MPH AND THEN WHEN APPROACHING A STOP A JERKY SHIFT WOULD OCCUR AT APPROX 5-10 MPH. SERVICE ENGINE SOON ILLUMINATED CAR WOULD NOT ACCELERATE MORE THAN 10 MPH SO MY WIFE PULLED INTO A PARKING LOT AND SHUT THE CAR OFF. THE CAR WOULD NOT START AGAIN AND HAD TO BE TOWED. I HAD THE CODE PULLED FROM THE ECU AND IT REPORTED ERROR "P0717 INPUT TURBINE SPEED SENSOR CIRCUIT NO SIGNAL". AFTER SEARCHING ONLINE I FOUND A LOT OF INFORMATION ON DEFECTIVE RADIATOR IN 2005-2010 NISSAN PATHFINDER, XTERA AND FRONTIER WHICH ALLOWS COOLANT AND TRANSMISSION FLUID TO MIX AND CAUSES TRANSMISSION FAILURE WHICH WAS ALSO CONFIRMED BY CONTAMINATED COOLANT IN THE RADIATOR. THIS IS A SAFETY CONCERN AS THERE WERE NO SIGNS OF THIS FAILURE LIKE SO MANY PEOPLE HAVE REPORTED UNTIL ITS SUDDEN FAILURE AND THERE SHOULD BE A RECALL IN PLACE. HTTP://WWW.CARCOMPLAINTS.COM/NISSAN/PATHFINDER/2007/TRANSMISSION/COOLANT_LEAKED_INTO_TRANSMISSION.SHTML. *TR

MY 2007 NISSAN PATH FINDER WAS RECENTLY WAS DIAGNOSED WITH A COMPLETE FAILURE TO THE TRANSMISSION DUE TO A FAILURE OF THE "RADIATOR ASSEMBLY" THAT FAILED AND ALLOWED WATER TO GET INSIDE THE TRANSMISSION CONTAINMENT AND THIS CAUSED CATASTROPHIC FAILURE TO THE TRANSMISSION. REQUIRING NOW THAT THE WHOLE TRANSMISSION NEEDS TO BE REPLACED. THE ONLY WARNING I GOT WAS THE FAILURE WARNING LIGHT FROM MY CAR, AND AT THAT POINT ITS ALREADY DAMAGED. LOOKING FOR AN EXPLANATION I TURNED TO NISSAN AND I LEARNED THAT THIS IS RECOGNIZED BY NISSAN DEFECT AND THOUGHT MY VEHICLE HASN'T BEEN COMPLETELY ABANDON BY NISSAN CORP. I STILL HAVE TO CONTRIBUTE $2.5K TOWARDS REPAIRS FOR A KNOWN FAILING DESIGN, THAT FIXING IT COULD HAVE PREVENT THE MUCH MORE COSTLY RESULT OF LEAVING IT AS IS. WHAT HAPPENED TO NISSAN STANDING BY THEIR PRODUCT AND MAKING GOOD ON POOR DESIGN? EVEN WHAT'S MORE IS THAT I WAS MAILED A LETTER REGARDING A CLASS ACTION REIMBURSEMENT IN LEGAL LINGO THAT I DIDN'T FULLY UNDERSTAND AND FELT IT DIDN'T APPLY TO ME SINCE ID HAVE NO EXPENSES. YET IT NOW MAKES SENSE AS TO WHAT ITS PURPOSE WAS.. IT WAS TO MONETARY REIMBURSE THOSE WITH NISSAN'S AT MY SIMILAR AGE AND MILEAGE FOR REPAIR THEY PERFORMED DUE TO ADMITTING IT WAS A FAULTY DESIGN. I CANT HELP BUT WONDER WHAT HARM WOULD IT HAVE BEEN TO PUBLISH AN ADVISORY LETTER AND ALLOW THE CONSUMER THE RIGHT TO MAKE REPAIR PRIOR TO A COMPLETE FAILURE. ADDITIONAL NISSAN CONSUMER AFFAIRS DEPT. NEED A PERSONALITY TRAINING AS THEY ARE UNABLE TO SAY ANYTHING UNLESS IT IS PRE-SCRIPTED FOR THEM. I'M BEGINNING TO RETHINK MY FORTH VEHICLE PURCHASE TO NOT BE A NISSAN. *TR

RADIATOR COOLER LEAKING WATER INTO TRANSMISSION,AND TRANSMISSION OIL INTO COOLING SYSTEM. TRANSMISSION STUCK IN 3 GEAR, ENGINE OVERHEATING DUE TO SLUDGE INSIDE RADIATOR, A TOTAL DISASTER FOR A LOW INCOME INDIVIDUAL TRYING TO MAKE ENDS MEET . *TR

DRIVING CAR IN RUSH HOUR TRAFFIC AND CAR COMPLETING STOPPED. IT TOOK ABOUT 10 MINUTES TO START. ONCE THE CAR STARTED IT CRANKED FOR ABOUT 10 SECONDS BEFORE IT ACTUALLY STARTED. AT DEALERSHIP, THE CAR WAS DIAGNOSED WITH NEEDING TWO NEW CAM SENSORS. AFTER PAYING $621.00 FOR THIS, MECHANIC TEST DROVE CAR AND FOUND IT TO BE "BUCKING" AND DIAGNOSED THAT THE RADIATOR FLUID HAD LEAKED INTO THE TRANSMISSION AND WE NEEDED A WHOLE NEW TRANSMISSION. NISSAN IS REQUIRING $2,500 DEDUCTIBLE EVEN AFTER THEY REALIZE THEY MADE A FAULTY RADIATOR/TRANSMISSION. *TR

TRANSMISSION FLUID IS MILKY COLORED. LOSS OF COOLANT. TRANSMISSION SLIPPING. SOMEHOW COOLANT IN TRANSMISSION FLUID. *TR

THE FLUIDS OF THE RADIATOR AND TRANSMISSION MIXED. 3 MECHANICS AND A NISSAN DEALER SAID ITS A KNOWN ISSUE BETWEEN 2005~2007. AND NO RECALLS WE'RE BEING ISSUED. I HAD A DIAGNOSTIC TEST DONE AT ANTWERPEN NISSAN DONE WHEN MY PATHFINDER WAS RUNNING. I HAVE HAD A 95 SENTRY, I HAVE A 09 VERSA, I HAVE TALKED MY MOTHER IN LAW INTO A NISSAN ALTIMA, AS WELL AS MY STEP MOM. MY HUSBAND HAS TALKED A COUPLE OF HIS CO WORKERS INTO A NISSAN ALSO. I WANT TO KNOW WHY THERE HAS BEEN NO RECALLS ON A "WELL KEPT SECRET" AS THAT IS WHAT I WAS TOLD. *TR

BOUGHT 2007 NISSAN PATHFINDER FALL 2010. DEC 2010 IN FOR OIL CHANGE AT DEALERSHIP. SENT HOME PAPER W/ BOXES CHECKED SHOWING TRANSMISSION & COOLANT "MAY NEED FUTURE ATTENTION" NOTHING ELSE BROUGHT TO OUR ATTENTION. 40,912 MILES ON TRUCK. DEC 2013- 99,279 MILES- TOOK TRUCK TO DEALERSHIP- WASN'T HEATING AT IDLE. FOUND TO BE LOW ON COOLANT, CONTAMINATED TRANSMISSION FLUID, AND OIL SLUDGE IN THE ENGINE (OIL LIGHT DID NOT COME ON) THEY FLUSHED FLUIDS, REFILLED THEM & TOLD US TO CHANGE OIL EVERY 1,000 MILES FOR A FEW MONTHS TO ENSURE CLEAN. JAN 13 2014 ANOTHER OIL CHANGE, ANOTHER CHECKED BOX STATING TRANSMISSION FLUIDS "MAY NEED FUTURE ATTENTION" EVEN THOUGH FLUSHED 18 DAYS AGO. FEB 10 2014 ANOTHER OIL CHANGE, ANOTHER CHECKED BOX STATING COOLANT "MAY NEED FUTURE ATTENTION". THIS SEEMED TO BE ROUTINE AND NOTHING MORE SINCE FLUIDS ROUTINELY NEED CHANGING. FEB 27, 2014 -103,000 MILES- ENGINE LIGHT ON, DROVE IMMEDIATELY TO DEALERSHIP. DIAGNOSIS: COOLANT HAD LEAKED INTO THE TRANSMISSION FROM THE RADIATOR RUINING BOTH. $5,000+ TO FIX.FOUND THERE ARE OVER 110,000 NISSAN PATHFINDERS WITH EXACT PROBLEM, NISSAN IS/HAS BEEN AWARE OF THIS, BUT SINCE THERE IS NO RECALL THEY DON'T HAVE TO INFORM OWNERS. THERE IS A CLASS ACTION LAWSUIT. BECAUSE OF THIS, WARRANTY WAS EXTENDED TO 100,000 MI. BUT, THIS IS HAPPENING RIGHT AROUND OR AFTER 100,000, IT IS TOO LATE. NISSAN WILL ONLY PAY FOR ANYTHING OVER $3,000, BUT ARE INSTALLING REBUILT TRANSMISSIONS THAT COST JUST THAT, SO WE ARE STILL PAYING TOTAL COST. VISITS SHOW THAT AT 40,912 & 99,279 MILES THEY KNEW THIS WAS THE PROBLEM DID NOT INFORM US SINCE THEY WOULD HAVE BEEN LIABLE. A MECHANIC OF 30 YEARS EXPLAINED THAT LOW COOLANT AND COLD ON IDLE MEANS THERE IS A LEAK WHICH WILL ALSO CAUSE OIL SLUDGE. VISITS 1& 2 MOS LATER ALSO SHOWED SIGNS OF LEAKAGE. SIGNS WERE ALL THERE AND IGNORED! DANGEROUS IF HAPPENS WHILE DRIVING. *TR

MY VEHICLE JUST COMPLETELY SHUT DOWN WITHOUT ANY WARNING SIGNS OR PREVIOUS ISSUES. I HAVE TAKEN VERY GOOD CARE OF THIS VEHICLE AND THE RADIATOR HAS A MANUFACTURER DEFECT THAT ALLOWED TRANSMISSION FLUID TO LEAK INTO THE RADIATOR CAUSING CATASTROPHIC DAMAGE TO MY RADIATOR AND TRANSMISSION THAT NISSAN WILL NOT TAKE ANY RESPONSIBILITY FOR AND WILL COST ME UPWARDS OF $5,200.00 AT LEAST. *TR
