I WAS DRIVING MY PATHFINDER DOWN THE HIGHWAY AND WHEN I REACHED 40 MPH, IT BEGAN TO HESITATE AS IF THE OVERDRIVE WAS NOT WORKING. AS I GAVE IT MORE GAS, IT STOPPED. IT HAS GRADUALLY GOTTEN WORSE TO THE POINT THAT ANYWHERE FROM 40 TO 50 MPH, THE VEHICLE IS HESITATING UNLESS YOU EITHER SLOW TO BELOW 40 OR SPEED UP TO ABOVE 50. I TOOK IT TO THE NISSAN DEALER AND HE STATED THAT THE TRANSMISSION FLUID WAS MIXING WITH THE COOLANT, WHICH MEANS THAT I MUST PAY TO HAVE MY TRANSMISSION REPLACED OR PURCHASE A NEW VEHICLE! I HAVE SINCE HEARD THAT THERE HAVE BEEN MANY REPORTS OF THIS SAME ISSUE. MY VEHICLE HAS GONE OUT OF WARRANTY, BUT, IF THIS IS AN ISSUE THAT HAS BEEN KNOWN FOR QUITE SOME TIME (YEARS) AS I HAVE RESEARCHED, THEN I BELIEVE NISSAN SHOULD HAVE TO COVER THE COST OF REPLACEMENT. WHY WAS THERE NOT A RECALL ON THE ISSUE, WHICH COULD HAVE BEEN FIXED EASILY INSTEAD OF HAVING TO REPLACE THE WHOLE THING AT THE OWNERS EXPENSE! I ALSO REALIZE THAT AT ANY MOMENT MY VEHICLE COULD STOP IN THE MIDDLE OF THE ROAD, WHICH COULD CAUSE INJURY OR EVEN DEATH TO ME OR MY FAMILY. *TR

NOW VEHICLE HAS ABOUT 75000. DRIVING HOME FROM DINNER WITH WIFE IN MODERATE TRAFFIC. HERD A CLUNK AND CAR WOULD NOT ACCELERATE. BARELY MADE IT HOME. I LET VEHICLE COOL DOWN AND REMOVED THE RADIATOR CAP AND FOUND THICK CREAM LIKE FLUID WHICH IS A DEFINITE SIGN OF OIL BASED FLUID CONTAMINATED WITH WATER / GLYCOL. SEEMS TO ME THAT NISSAN DID NOT REPLACE OR FIX THE LEAKING RADIATOR. DRIVING A VEHICLE THAT BEHAVES IN THIS MANNER CAN NOT BE SAFE TO DRIVE. BACK TO THE SHOP (DEALER) TOMORROW. *TR

CALSONIC RADIATOR ISSUE - TRANSMISSION FLUID AND COOLANT MIXED CAUSING ISSUES WITH TRANSMISSION. BAD TRANSMISSION COOLER AREA PER AAMCO. NISSAN IS UNWILLING TO HELP AS MY VEHICLE HAS 126K MILES ON IT. THESE ISSUES APPEAR TO BE HAPPENING IN A MUCH GREATER % THAN NISSAN IS ACKNOWLEDGING. THEY MOVED THE WARRANTY FROM 3 YRS/36000 MILES TO 8 YEARS/80000 MILES BUT IT STILL DOESN'T HELP THOSE WHOSE RADIATOR LEAKED AFTER THE 100K LEVEL PREMATURELY. THIS IS A SAFETY ISSUE AND ALSO A MANUFACTURING DEFECT ISSUE. IT SEEMS THAT NISSAN CORPORATE, DEALERS, TRANSMISSION SHOPS AND OTHER GOVERNMENTAL ORGANIZATIONS KNEW ABOUT THIS ISSUE - SADLY, MOST CONSUMERS DON'T. I WOULD HAVE GLADLY REPLACED MY RADIATOR FOR $500 BUT NOW I WILL BE OUT $4000 BECAUSE NISSAN DIDN'T TELL THEIR OWNERS ABOUT THIS PROBLEM. *TR

NOW I KNOW THAT THEY ARE TAKING SOME RESPONSIBILITY BUT REALLY HOW IS IT THAT I SHOULD RESPONSIBLE TO PAY FOR ANY PORTION OF THIS REPAIR. IT SHOULD BE A RECALL NO MATTER HOW MANY MILES. I DIDN'T KNOW THAT I WAS BUYING A CAR THAT WAS GOING TO LAST FOR 90,000 MILES I MIGHT HAVE WENT A DIFFERENT DIRECTION. IF IT WAS A NISSAN DEFECT WHY DO WE THE CONSUMER HAVE TO PAY FOR THIS? PLEASE HELP OUT THE MANY NISSAN OWNERS WHO ARE UPSET AND CONFUSED AT WHY THIS BURDEN SHOULD BE PUT ON US. THANK YOU. *JB

NOTE: AFFECTED PARTS ARE TRANSMISSION AND RADIATOR (NOT SURE WHAT CATEGORY THOSE FALL IN) I PURCHASED A 2007 NISSAN PATHFINDER FROM A NISSAN DEALERSHIP LESS THAN 3 MONTHS AGO. IMMEDIATELY AFTER PURCHASING I NOTICED WHAT SEEMED TO BE A MINOR LACK OF POWER OR CUTTING OUT WHEN COASTING DOWNHILL. I MENTIONED IT TO MY SALES REP, AND AGAIN WHEN I HAD TO TAKE THE VEHICLE BACK TO THE SHOP ON TWO SEPARATE OCCASIONS FOR A TIRE PRESSURE GAUGE AND REAR DOOR HANDLE PROBLEM. I HAD NEVER OWNED A 4WD BEFORE AND IT WAS DISMISSED AS NO BIG DEAL SINCE IT STILL DROVE OKAY. THEN LAST WEEK, OVER LABOR DAY WEEKEND, MY CAR OVERHEATED AND IMMEDIATELY DISCHARGED A GREY MILKY SUBSTANCE FROM THE RADIATOR WITHOUT WARNING. IT HAD NOT OVERHEATED PRIOR TO THIS. I HAD MY CAR TOWED TO THE DEALERSHIP. THEY INFORMED ME THAT BOTH THE TRANSMISSION AND THE RADIATOR NEED REPLACING TO THE TUNE OF $6,600. THE CAUSE BEING THE RADIATOR FLUID LEAKING INTO THE TRANSMISSION. THIS REPAIR IS OVER HALF THE VALUE OF THE CAR. I NEVER WOULD HAVE PURCHASED THE VEHICLE HAD I KNOWN ABOUT THE DEFECT. AT A MINIMUM I WOULD HAVE INSISTED IT BE COVERED BY WARRANTY. I PAID FULL RETAIL PRICE FOR THE CAR NOT KNOWING OF THIS DEFECT. WHILE I'M GRATEFUL NO ONE WAS INJURED BY THIS DEFECT THIS TIME, I HAVE NO MEANS TO PAY THE REPAIR COSTS AND OWE $13,000 TO THE BANK FOR A VEHICLE I CANNOT DRIVE OR RESELL. *JB

THIS PATHFINDER IS EXPERIENCING A FAILURE WITH THE TRANSMISSION OIL COOLER / RADIATOR ASSEMBLY AND IS WITHIN THE 10 YEAR PERIOD SPECIFIED BY THE EXTENDED WARRANTY BUT IS BEYOND THE 100,000 MILE LIMIT. DUE TO THE NATURE OF THIS DEFECT, THE SEVERITY OF THIS FAILURE, THE REPETITIVE NATURE OF THE FAILURES AND THE LIMITED OR MISSING FAILURE WARNING SIGNS, I BELIEVE THAT AN INVESTIGATION IS WARRANTED. EXTENDING A WARRANTY FOR A SHORT PERIOD OF TIME A LIMITED MILEAGE THAT MOST CONSUMERS BREEZE THROUGH IN A FEW YEARS IN ORDER TO AVOID A RECALL IS NOT GOOD FOR REPEAT BUSINESS OR SAFETY. NISSAN SETTLED A CLASS ACTION LAWSUIT WHERE IT IDENTIFIED THE DEFECTIVE RADIATOR, BUT CAPPED THE WARRANTY AT 10 YEARS/100,000 MILES. WHETHER OR NOT THE INCIDENT HAPPENED AT 10,000 MILES, OR 200,000 MILES, IT IS STILL A MANUFACTURE DEFECT, NOT CAUSED BY THE CONSUMER. SIMPLY EXTENDING THE WARRANTY COVERAGE FOR THE RADIATOR WITHOUT WARNING CONSUMERS OF THE CONSEQUENCES TO THE TRANSMISSION ONLY MAKES SENSE TO ME IF NISSAN IS LOOKING TO CUT THEIR LOSSES. WHY DIDN'T NISSAN WARN CONSUMERS THAT THE TRANSMISSION COULD FAIL VERY QUICKLY AS A RESULT OF A CRACKED COOLER TUBE? HOW MANY CONSUMERS MUST NEEDLESSLY SUFFER TRANSMISSION FAILURES IN BUSY INTERSECTIONS AND ON BUSY, CONGESTED HIGHWAYS BEFORE NISSAN DOES THE ETHICAL THING AND ISSUES A SAFETY RECALL? THIS DEFECT NEED NOT BE LEFT ON THE CONSUMER'S SHOULDERS, AND COULD VERY EASILY CAUSE SAFETY ISSUES FOR THE OWNER. *TR

On February 29, 2012 the National Highway Traffic Safety Administration (NHTSA) received a letter petitioning the agency to conduct a defect investigation into MY 2005-2010 Nissan Pathfinder, Frontier, and Xterra vehicles [the subject vehicles] for automatic transmission failures related to failed transmission coolers.NHTSA conducted a comprehensive review of data related to this subject. 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.
