AFTER RECEIVING A COMPLIMENTARY MULTI-POINT INSPECTION FROM THE LOCAL NISSAN DEALERSHIP, MY WIFE TOLD ME THAT ON THE WAY HOME THAT THE TRANSMISSION SEEMED TO NOT WANT TO SHIFT PROPERLY. WENT TO CHECK TRANSMISSION FLUID AND FOUND THAT THE DIPSTICK IS LOCKED INTO PLACE. DID SOME QUICK RESEARCH TO FIND OUT HOW TO CHECK FLUID LEVEL AND THEN FOUND OUT ABOUT ISSUE WITH NISSAN PATHFINDERS RADIATORS HAVING A PROBLEM WITH LEAKING COOLANT INTO THE TRANSMISSION COOLING SYSTEM. CHECKED RADIATOR AND FOUND FROTHING FOAM ON THE INSIDE OF THE PRESSURE CAP INDICATING THAT THE RADIATOR HAD FAILED. CONTACTED DEALERSHIP AND ASKED THEM WHY THE SECTION OF THE INSPECTION FOR THE COOLING SYSTEM AND TRANSMISSION SYSTEM WERE CHECKED AS "OK". DID NOT RECEIVE AN ANSWER. ALSO, WE WERE NEVER NOTIFIED BY NISSAN ABOUT THE ISSUE WITH RADIATOR IN OUR NISSAN. THE VEHICLE IS CURRENTLY PARKED SINCE THE DEALERSHIP SAID IT WOULD COST UP TO $3000 DOLLARS IN REPAIRS UNDER THE AGREEMENT REACHED. I DO NOT UNDERSTAND WHY THIS WAS NOT A RECALL. THIS SITUATION COULD OF CAUSED A CATASTROPHIC FAILURE OF THE TRANSMISSION AT SPEED WHILE DRIVING OR CATASTROPHIC FAILURE OF THE ENGINE BECAUSE OF LACK OF COOLING CAUSING THE ENGINE TO SEIZE UP AT SPEED WHILE DRIVING.

THE VEHICLE HAS HAD ALL SORTS OF ISSUES STARTING WITH THE BRAKES WHEN ONE BRAKE SHOE TOTALLY DISINTEGRATED AND EVIDENTLY RUPTURED BRAKE LINES AT AROUND 61,000 MILES. NEW BRAKE REPLACEMENT ALMOST $900. SINCE THAT TIME (THE VEHICLE NOW HAS 75000 MILES) THE TRANSMISSION HAS CONTINUALLY SLIPPED, THE GAS GAUGES AND ALL OTHER GAUGES WORK INTERMITTENTLY, AND THE EMISSIONS TEST LAST MONTH SHOWED POSSIBLE CATALYTIC CONVERTER ISSUES (THERE ARE EVIDENTLY TWO). WHEN TAKEN IN FOR SERVICE THE SERVICE TECHNICIAN SUGGESTED I GET RID OF THE VEHICLE BECAUSE IT WAS NOTORIOUS FOR CROSS CONTAMINATION OF COOLANT AND TRANSMISSION FLUID. CONTINUING TO DRIVE IT WOULD EVENTUALLY DESTROY THE TRANSMISSION, AND EVEN NOW MAY HAVE PERMANENT DAMAGE. WHEN CONTACTING NISSAN ABOUT POSSIBLE RECALLS AND THE SUPPOSED SETTLED CLASS ACTION LAWSUIT CONCERNING THE TRANSMISSION CONTAMINATION, I WAS TOLD I WOULD NEED DOCUMENTATION OF ALL SERVICE DONE TO THE VEHICLE TO RECEIVE $800 TOWARD THE NECESSARY $3800 REPAIR COST JUST FOR THE CONTAMINATION LEAK. IF ANYONE IS CONSIDERING PURCHASING THIS OR ANY OTHER NISSAN PRODUCT, I WOULD AVOID IT AT ALL COST.

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.
