NHTSA Complaint #10576939 — 2007 NISSAN FRONTIER

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
