COMING HOME FROM WORK THE TRUCK STARTED TO OVERHEAT AND THE TRANSMISSION STARTED TO SKIP. I HAD TO TURN ON THE HEATER TO KEEP THE TRUCK FROM OVERHEATING AND THEN THE TRANSMISSION STARTED TO ENGAGE AND DISENGAGE. THE PROBLEM IS THAT THE ANTIFREEZE IS LEAKING IN TO THE TRANSMISSION. THIS IS A KNOWN PROBLEM WITH NISSAN, BUT THEY ARE NOT FIXING THE PROBLEM. I HAVE THREE CHILDREN THAT ARE IN THE TRUCK WITH ME. IF THAT TRANSMISSION BREAKS AND CAN CAUSE MAJOR PROBLEMS. NISSAN NEEDS TO REPLACE THE PARTS. *TR

MY VEHICLE HAS DEVELOPED A VIBRATION WHILE I AM DRIVING WHICH HAS BEEN VERY UNCOMFORTABLE, HOWEVER, NOTHING MAJOR IN THE PERFORMANCE OF THE VEHICLE, HOWEVER, NOW MY VEHICLE HAS DECIDED TO RANDOMLY TURN OFF WHILE DRIVING. THIS IS EXTREMELY DANGEROUS AND COULD CAUSE AN ACCIDENT. I TOOK IT TO THE NISSAN DEALERSHIP AND THEY SAID THAT THEY FOUND TRANS FLUID MIXING WITH COOLANT DUE TO LEAKING TRANS COOLER IN RADIATOR AND THE TOTAL COST WOULD COME OUT TO $5,000. I AM UNABLE TO AFFORD THIS BILL SO I HAVE NOT BEEN ABLE TO REPAIR MY VEHICLE. *TR

AT ABOUT 85,000 MILES ON THE TRUCK, WHILE CRUISING AT AROUND 40 MPH THE GEARS DROPPED AND STUTTERED. I BROUGHT IT TO THE DEALERSHIP AND THEY DOCUMENTED MY CONCERN AND THE INCIDENT. THEY DID A DIAGNOSTIC AND ONLY CAME UP WITH A FUEL GAUGE MALFUNCTION AND REPLACE IT FOR $475. AT 90,000 MILES I DESCRIBED THE SAME CONCERN, WHICH THEY DOCUMENTED, AT A LOWER MPH AND THEY FLUSHED/REPLACED TRANS AND RADIATOR FLUID AND REPLACED THE RADIATOR ITSELF FOR $1600. I AM NOW BEING TOLD THAT THE ENTIRE TRANSMISSION NEEDS TO BE REPLACED FOR APPROXIMATELY $6000. NISSAN HAS TO DO SOMETHING ABOUT THIS, IT STANDS TO REASON THAT THE CAUSE OF THE TRANSMISSION MALFUNCTION IS DUE TO COOLANT GETTING INTO A LUBRICANT. *TR

BROUGHT TO DEALERSHIP AND WAS DIAGNOSED WITH ANTI FREEZE MIXING WITH TRANSMISSION FLUID WHICH IS A WELL KNOWN PROBLEM NOW WITH NISSAN.

NISSAN HAS A KNOWN PROBLEM WITH THE RADIATOR AND TRANSMISSION. THE DATE LISTED IS MERELY THE DATE WE DISCOVERED THE ISSUE. BEFORE JAN 31, 2012 WE KNEW NOTHING ABOUT THIS PROBLEM. IT IS A SAFETY ISSUE. YOU DON'T KNOW IF THIS HAS HAPPENED TO YOUR TRUCK UNTIL IT OVERHEATS AND YOU FIND OUT THE FLUIDS HAVE MIXED. REPLACE THE RADIATOR. FLUSH THE FLUIDS (3 OR MORE TIMES, SINCE THE FLUID IS NOW LIKE PURPLE SOFT SERVE ICE CREAM). THEN THE REAL TROUBLES BEGIN.. IT SLIPS OUT OF GEAR WHILE DRIVING AT 70 MPH AND THE ONLY OPTION IS TO PULL OVER, TURN THE TRUCK OFF, REMOVE THE KEY, THEN RESTART THE TRUCK AND HOPE IT WORKS. THIS IS REALLY DANGEROUS ON THE HIGHWAY AT THE HIGHER SPEEDS BUT ALSO UNSAFE ON THE SIDE ROADS OR IN STOP AND GO TRAFFIC. I TAKE MY KIDS TO SCHOOL 3.6 MILES EACH WAY. I HAVE TO STOP AND RESTART THE TRUCK AT LEAST 3 TIMES DURING THE ROUND TRIP. SPEED DOESN'T MATTER. YOU STOP AT A RED LIGHT AND HAVE KNOW IDEA IF IT IS GOING TO GO WHEN YOU PUSH THE GAS OR NOT. PULLING OUT INTO TRAFFIC CAN BE VERY DANGEROUS SINCE YOU HAVE TO GO AND YOU FIND OUT YOU CAN'T. THERE HAVE BEEN SEVERAL "WARRANTY EXTENTIONS" ISSUED BY NISSAN ON OUR TRUCK THAT WE WERE NOT AWARE OF UNTIL AFTER MAKING THE REPAIRS ON OUR OWN DIME. THERE IS A "WARRANY EXTENTION" FOR THIS ISSUE DUE TO A CLASS ACTION LAWSUIT BUT IT DOES NOTHING FOR A LOT OF THE OWNERS SINCE MANY ARE OVER THE "EXTENTION MILEAGE". I TRY TO NEVER DRIVE THE TRUCK ON BUSY ROADS WITHOUT SHOULDERS OR TURN LANES, I FEAR RED LIGHTS AND TRAFFIC BUT STOP SIGNS ARE THE WORST... I NEVER KNOW IF THE TRANSMISSION IS GOING TO WORK OR NOT. ALL BECAUSE A KNOWN FAULTY RADIATOR CRACKED AND LEAKED FLUID INTO THE TRANSMISSION. BUT, I'M OVER THE EXTENDED MILEAGE SO I'M EXPECTED TO PAY OVER $5K TO FIX A KNOWN ISSUE. *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.
