I HAVE A 2007 NISSAN FRONTIER WHICH HAS ONLY A 122,431 MILES ON IT AND SOMETHING WENT WRONG WITH THE TRANSMISSION. WHEN I WAS GOING UP THE HILL IT WAS LIKE IT JUST STALLED OUT ON ME. I'VE BEEN DOING RESEARCH ON IT AND IT SEEMS LIKE ALOT OF OTHER PEOPLE IS HAVING THE SAME PROBLEM AND IT SEEMS LIKE NISSAN IS JUST TRYING TO HIDE THE PROBLEM. IF ITS SOMETHING THAT THEIR AT FAULT WITH THEY SHOULD BE THE ONE WHO FIXES IT. I DEPEND ON MY TRUCK EVERYDAY TO GET ME TO WORK AND IF ITS THE COOLANT AND TRANSMISSION FLUID IS MIXING ITS A VERY EXPENSIVE FIX WHICH I CAN'T AFFORD AND THE OTHER PEOPLE SHOULDN'T BE RELIABLE FOR SO I WISH U WOULD CONSIDER THIS AND DO AND INVESTIGATION ON IT AND TRY AND GET THIS PROBLEM FIXED BEFORE IT MESSES ANYBODY ELSE'S UP AND PUTS THEM OUT ALOT OF MONEY. THERE'S JUST TO MANY PEOPLE ON THE INTERNET WITH THE SAME PROBLEM AND IF U ALL DON'T DO SOMETHING ABOUT IT NISSAN IS JUST GOING TO KEEP DOING THE SAME THING TIL SOMEONE DOES SOMETHING ABOUT IT. THANK YOU FOR YOUR TIME *TR

THE AUTOMATIC TRANSMISSION STARTED SHIFTING "HARD" AND THE HEATER STOPPED WORKING. I TOOK IT TO A LOCAL SHOP AND THEY TOLD ME THAT THE RADIATOR FLUID HAD CONTAMINATED THE TRANSMISSION FLUID, AND VISA VERSA. I NEEDED TO HAVE A TRANSMISSION SHOP LOOK AT IT. THEY TOLD ME THE SAME THING AS THE PREVIOUS SHOP, BUT ALSO THAT I WOULD BE NEEDING A NEW TRANSMISSION AND RADIATOR SYSTEM, AT THE COST OF $4848.00. THIS WAS DUE TO A FAILED TRANSMISSION FLUID COOLER LOCATED IN THE RADIATOR ASSEMBLY THAT ALLOWED COOLANT TO MIX WITH AND CONTAMINATE THE AUTOMATIC TRANSMISSION FLUID, RESULTING IN DAMAGED INTERNAL TRANSMISSION COMPONENTS AND A DAMAGED INTERNAL TRANSMISSION COMPUTER. AFTER RESEARCHING, THIS HAS OCCURRED TO HUNDREDS OF NISSAN VEHICLES, INCLUDING 2005-2010 NISSAN PATHFINDER, FRONTIER AND XTERRA VEHICLES. NISSAN HAS BEEN AWARE OF THIS PROBLEM SINCE 2007 AND HAS UNDERTAKEN NO PREVENTIVE MEASURES TO PROTECT CONSUMERS FROM FAILURE. *TR

I PURCHASED THIS TRUCK FROM A USED CAR AUTO DEALER WITH 137,477 MILES ON IT. THEIR WARRANTY WAS UP BEFORE I WAS AWARE I HAD A SERIOUS PROBLEM THAT GOT PROGRESSIVELY WORSE. WHILE DRIVING LOCALLY AND ON THE HIGHWAY AT SPEEDS BETWEEN 35 AND 65 MPH THE TRUCK STARTED TO SHAKE AND VIBRATE INTERMITTENTLY WHICH CAUSED AN ERRATIC CONTROL OF THE TRUCK. AFTER APPROACHING SEVERAL AUTO REPAIR SHOPS ABOUT THE ISSUE NO ONE SEAMED TO HAVE A SOLUTION EXCEPT ONE. THEY TOLD ME THAT A CLASS ACTION SUIT WAS ISSUED AGAINST NISSAN ABOUT A DEFECTIVE TRANSMISSION AND RADIATOR COMBINATION COOLER CROSS CONTAMINATE PROBLEM THAT DESTROYS THE TRANSMISSION LUBRICATE AND ELECTRICAL SHIFTING FUNCTIONS OF THE TRANSMISSION. IT COST ME $3,728.95 TO FIX THE PROBLEM AND I WOULD LIKE TO GET MY MONEY BACK FROM NISSAN IF POSSIBLE. ALL POST ABOUT THE CLASS ACTION SUIT PUTS ME OUTSIDE ON THE INITIAL SETTLEMENT. THANK YOU *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.
