VEHICLE BEGAN RUNNING POORLY AND STUTTERING BETWEEN GEAR SHIFTS. KNEW ABOUT THE POTENTIAL FOR THE TRANSMISSION AND RADIATOR FLUID TO MIX AND DESTROY THE ENGINE FROM THE LAWSUIT THAT WAS FILED AND CORRESPONDENCE WE HAD RECEIVED FROM NISSAN. SURE ENOUGH, TOOK THE VEHICLE TO A NISSAN DEALER AND AN INDEPENDENT CAR SHOP AND BOTH DIAGNOSED THE SAME THING - RADIATOR AND TRANSMISSION FLUIDS MIXING. NO OPTION BUT TO GET IT REPAIRED FOR A WHOPPING $4,409.26. IT IS DISGRACEFUL THAT NISSAN WILL NOT FORMALLY ACKNOWLEDGE THIS DEFECT AND PAY FOR THE REPAIR BILL NO MATTER WHAT YOUR MILEAGE. THIS WAS OUR FIRST AND LAST NISSAN. *TR

WHEN I TURNED ON IGNITION, GEAR SHIFT WAS LOCKED. I UNLOCKED MANUALLY AND TRIED TO START. NOTHING. ENGINE WILL NOT CRANK. NO LIGHTS ON DASH. I TOWED IT MY LOCAL MECHANIC WHO TRIED SOME ELECTRICAL WORK. NOTHING SO HE THOUGHT A TRANNY FAILURE PUT TRUCK IN FAILSAFE. AAMCO COULD NOT START IT SO THEY COULD NOT DIAGNOSE. TOWED IT TO NISSAN. THEY WANTED TO CHANGE TRANNY FOR $8000 NEW OR $5000 USED. TOO MUCH MONEY FOR A VEHICLE W/ 110000 MILES. I TOWED IT OUT TO ANOTHER TRANSMISSION PLACE AND THEY FIRST THOUGHT IT WAS THE STARTER! THEY CHANGED THE STARTER, NOTHING DOING. OF COURSE JUMP START IS NOT WORKING SO ITS NOT THE BATTERY. IM NOW STUCK. PREVIOUSLY TRUCK HAD STALLED ONCE ON THE HIGHWAY AT ABOUT 60000 MILES AND WOULD ONLY DRIVE ON GEAR #1. TOOK IT TO NISSAN DEALERSHIP. THEY SAID THEY COULDN'T FIND ANY PROBLEM WITH TRANNY BUT THEY REPLACED THE TRANSMISSION FLUID. LATER AT ABOUT 101K THE TRANSMISSION STARTED SLIPPING AND NISSAN FOUND THAT THE ANTIFREEZE HAD LEAKED INTO THE TRANSMISSION. THEY WANTED TO GIVE ME $2500 TOWARD A $7300 REPAIR. THEY ALSO OFFERED TO GIVE ME EMPLOYEE PRICING ON A NEW FRONTIER BUT I DONT WANT ANOTHER FRONTIER, SO I REFUSED AND INSTEAD TOOK IT TO MY MECHANIC. HE PUT IN A NEW RADIATOR AND FLUSHED THE TRANSMISSION. EARLIER AT ABOUT 46000 MILES, THE FUEL GAUGE STOPPED WORKING AND THE FUEL SENDER WAS CHANGED. NISSAN REFUSED TO HELP AT THAT TIME BUT LATER INITIATED A RECALL AND COMPENSATED ME FOR THE EXPENSE. ITS BEEN ALL PAIN WITH THIS TRUCK WHICH I BOUGHT "NEW" FROM A DEALER WITH ONLY 300 MILES ON IT.

AS I WAS PARKED AT A SERVICE STATION, I PUT MY TRUCK INTO REVERSE AND IT WAS THE SAME AS NEUTRAL AND NEVER ENGAGED. THIS IS A VERY COMMON, BUT NOT NECESSARY, ISSUE WITH THE TRANSMISSION ON THE NISSAN FRONTIER. I ALMOST BLEW UP MY ENGINE LAST YEAR WHEN THE RADIATOR CRACKED AND ALLOWED TRANSMISSION FLUID TO MIX WITH THE COOLANT AND CAUSED THE TEMPERATURE GAUGE TO GO WAY UP. THIS MIXTURE MADE ITS WAY TO THE TRANSMISSION AND HAS CAUSED IRREPARABLE DAMAGE; UNDOUBTEDLY, THIS IS WHY I NO LONGER HAVE REVERSE. I REPLACED THE RADIATOR AND FLUSHED MY TRANSMISSION FLUID THREE TIMES LAST YEAR AND THOUGHT I MAY HAVE FIXED THE PROBLEM. EVIDENTIALLY, THE DAMAGE HAD ALREADY BEEN DONE. THIS PROBLEM IS VERY WELL KNOWN TO NISSAN AND, AS A NISSAN FRONTIER OWNER, I WAS NEVER NOTIFIED REGARDING THIS POSSIBLE ISSUE. I UNDERSTAND THAT NISSAN HAS AGREED TO SETTLE WITH OWNERS WITHIN A CERTAIN MILEAGE RANGE; HOWEVER, MY TRUCK IS ONLY 5.5 YEARS OLD AND EXCEEDS THE MILEAGE REQUIREMENT BECAUSE MY OCCUPATION REQUIRES ALOT OF HIGHWAY TIME WHICH HAS PUT ALOT OF MILES ON IT. I FEEL NISSAN NEEDS TO STEP UP AND TAKE CARE OF THIS PROBLEM WITH ALL OWNERS OF THESE VEHICLES BEFORE SOMEONE GETS HURT OR KILLED IF IT HASN'T HAPPENED ALREADY. MY TRUCK IS NOW RENDERED USELESS UNTIL I PAY THOUSANDS OF DOLLARS TO FIX IT. THIS SHOULD NOT BE MY PROBLEM AT ALL!! *TR

AT ABOUT 100,000 MILES, I STARTED NOTICING THAT ON TAKE-OFF AND AT ABOUT 40 MPH, MY FRONTIER WOULD STRUGGLE TO TAKEOFF OR ACCELERATE. WHEN SLOWING DOWN, IF ACCELERATION WAS NEEDED, THE RPMS REV UP, BUT THE TRUCK DOES NOT ACCELERATE. AT 40-45 MPH TRANSITION, GOING UPHILL, THE TRUCK STUTTERS LIKE IT DOESN'T KNOW WHAT GEAR TO ENGAGE. I IMMEDIATELY LOOKED ONLINE AND FOUND MANY COMPLAINTS ABOUT THE VEHICLE TRANSMISSION HAVING A SLEW OF ISSUES RELATED TO TRANSMISSION FLUID COOLER LEAKS. I MOVED TO DRAIN THE FLUID SO THAT I COULD INSPECT THE COLOR AND COMPOSITION. IT WAS FINE. I REPLACED THE FILTER AND FLUID. LET IT BREAK IN FOR A BIT AND HAD SAME PROBLEMS. I HAD 2 DIFFERENT LUBE SHOPS REPLACE THE FLUID AND FLUSH THE TRANSMISSION AND THE PROBLEMS PERSIST. I CALLED UP THE DEALER AND THEY TOLD ME THAT A NEW TRANSMISSION WOULD COST 6800 + LABOR. HE SAID IT WAS VERY LIKELY THE FLUID ISSUE, BUT I WAS OUTSIDE THE WARRANTY PERIOD. THIS IS A DESIGN FLAW THAT NISSAN KNEW ABOUT FROM THE TIME THEY RELEASED THESE VEHICLES TO THE PUBLIC. THIS IS A SAFETY HAZARD IN THE NEED OF ACCELERATION AT A TRAFFIC LIGHT, TRAIN CROSSING AND MANY OTHERS. I WOULD LIKE TO REQUEST AN INVESTIGATION ON THE NUMBER OF THESE VEHICLES BEING INVOLVED IN ACCIDENTS. MY VEHICLE IS A 2007 NISSAN FRONTIER SE, VIN: [XXX].

THIS INCIDENT FORCED ME TO TAKE IMMEDIATELY ACTION AND PULL TO THE SIDE OF THE ROAD, WHICH PUT MY LIFE IN DANGER DURING RUSH HOUR TRAFFIC. I LEARNED FROM THE NISSAN DEALERSHIP THAT THE TRANSMISSION IN VEHICLES THAT WERE MANUFACTURED THE SAME YEAR, MAKE AND MODEL, WERE DEFECTED BUT THERE WAS NO RECALL. SINCE THAT TIME, APRIL 5, 2013 TO BE EXACT, THE TRANSMISSION IN MY VEHICLE HAS FAILED BECAUSE OF A MANUFACTURERS DEFECT. SOMETHING NEEDS TO BE DONE ABOUT THIS HAZARDOUS THREAT TO CONSUMERS BEFORE SOMEONE GET SERIOUSLY INJURED OR KILLED. *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.
