MY WIFE WAS DRIVING WITH KIDS IN THE VEHICLE WHEN POWER IN THE TRANSMISSION WHEN TO NOTHING THEN SPORADICALLY STARTED WORKING AND NOT. SHE INTELLIGENTLY WAS ABLE TO AVOID AN ACCIDENT AND GET THE VEHICLE TO A SIDE ROAD IN A BOAT RAMP PARKING AREA WHERE THE VEHICLE WOULD NOT RUN IN ANY GEAR. I WAS CALLED AND MADE AWARE OF THE SITUATION AND CALLED MY PARENTS TO PICK THEN UP FOR THIS WAS OUR ONLY VEHICLE OF TRANSPORTATION. AFTER WORK MY DAD, UNCLE AND I HAD THE VEHICLE TOWED TO OUR HOME WHERE IT HAS SET SINCE. DUE TO FINDING OUT THAT NISSAN ALREADY HAD A CLASS ACTION LAWSUIT OVER THIS AND THE RULING WITH THE MILEAGE ON MY VEHICLE DOES NOT FALL INTO ANY COMPENSATION OR ASSISTANCE TO BE FIXED THOUGH THE VEHICLE IS ONLY SIX YEARS OLD. JUST DON'T UNDERSTAND HOW TRANSMISSION FAILURE ON A BUSY ROAD DOES NOT CONSTITUTE A SAFETY RECALL. MY UNDERSTANDING OF ISSUE DOESN'T SEEM TO BE MILEAGE RELATED AS MUCH AS TIME OF THE PROBLEM TO HAPPEN. *TR

I WAS ON EXPRESSWAY, DRIVING APPROXIMATELY 60-65 MILES PER HOUR AND WITHOUT WARNING CAR LOST ALL ITS ABILITY TO ACCELERATE OR MAINTAIN SPEED. CAR ENGINE WOULD REV WHEN YOU PRESSED ON THE ACCELERATOR BUT THE CAR WOULD NOT RESPOND. VEHICLES BEHIND ME HAD TO HIT ON THERE BRAKES AND GO AROUND ME AS I ATTEMPTED TO STEER VEHICLE TO THE SIDE OF THE EXPRESSWAY. ONCE VEHICLE CAME TO A STOP, MY TRANSMISSION WOULD NOT ENGAGE IN ANY GEAR LEAVING ME STRANDED. I HAD TO HAVE VEHICLE TOWED TO MY HOME. I WAS INFORMED BY NISSAN THAT ENGINE COOLANT HAD LEAKED INTO MY TRANSMISSION AND RUINED MY TRANSMISSION. I HAVE SINCE FOUND OUT THIS IS A COMMON PROBLEM ON NISSAN PATHFINDERS AND THE COST TO REPAIR VEHICLE IS BETWEEN 4 AND 5 THOUSAND DOLLARS. *TR

THE VEHICLE VIBRATED AND SHUTTERED AND CEASED TO MOVE. I WAS IN TRAFFIC AND LUCKILY HAD A PLACE TO PULL OVER. I HAD THE VEHICLE TOWED TO THE LOCAL NISSAN DEALERSHIP. AFTER A DISCUSSION AND DIAGNOSIS BY THE TECHNICIAN AND SHOP FOREMAN IT WAS DETERMINED THAT THE TRANSMISSION AND THE RADIATOR HAD CROSSED CONTAMINATION OF FLUIDS RESULTING IN THE TRANSMISSION BECOMING INOPERABLE AND REQUIRING THE TRANSMISSION AND RADIATOR BE REPLACED. THE SHOP FOREMAN STATED THAT NISSAN KNEW ABOUT THIS DEFECT IN THE RADIATOR AND THE RESULTING PROBLEMS. I AM WAITING TO FIND OUT IF NISSAN WILL HELP WITH REPAIR COST. I WAS TOLD BY THE SHOP FOREMAN THAT THE COST TO REPLACE THE TRANSMISSION AND RADIATOR WOULD BE APPROXIMATELY $8,000.00. . *TR

THE TRUCK BEGIN TO SHIFT HARD AND RIDE AS IF ON GROOVES IN THE ROAD. AT TIME YOU WOULD HAVE TO REMOVE YOUR FEET FROM THE GAS SEVERAL TIMES TO STOP THE VIBRATION. THE TRUCK WOULD JERK WHILE DRIVING OR EXCEL VERY FAST WITHOUT WARNING. AFTER MONTHS OF THIS THE CHECK ENGINE SOON LIGHT CAME ON 11/19/13. I TOOK THE TRUCK INTO THE NISSAN DEALER TO FIND OUT WHAT THE PROBLEM WAS. THEY CAME BACK WITH A ESTIMATED INVESTMENT: TRANSMISSION, RADIATOR, MATIC S COOLANT. NO CODES OR ISSUES THAT WERE WRONG AND AT THE BOTTOM A GRAND TOTAL OF $5047.33. I WAS TOLD THE RADIATOR COOLANT LEAKED INTO THE TRANSMISSION CAUSING IT TO GO BAD. HE SAID THE COOLANT DAMAGES ALL THE INNER PARTS THROUGH CORROSION. I THOUGHT WHILE ALL THE REPORTS I HAVE READ ABOUT ONLINE ABOUT THE 2006-2010 MODELS NISSAN IS HAPPENING TO ME. SO WHAT DO I DO PAY A FORTUNE TO FIX A DEFECT THAT NISSAN HAS KNOWN ABOUT SINCE 2007 AND HAVEN'T RECALLED TO FIX THEM IN A CAR I JUST BOUGHT A YEAR AGO, THAT IS NO WHERE BEING PAID OFF. WE NEED SOME HELP WITH THIS THERE ARE COMPLAINTS FROM NC TO CANADA. THIS IS NOT OCCURRING IN VEHICLES UNDER WARRANTY OR EXTENDED WARRANTY BUT IN CARS THAT ARE OVER THE MILEAGE. THEY TOLD ME THE TRANSMISSION PRESSURE WAS TO MUCH. IT IS A SUV WITH POWER THEY SHOULD BE MADE TO PAY FOR THIS. *TR

THE VEHICLE WAS TRAVELING ON I-95 DURING RUSH HOUR TRAFFIC, THE VEHICLE WAS TRAVELING AT STOP AND GO SPEEDS DUE TO TRAFFIC CONGESTION AND WHEN THE OPERATOR WANTED TO ACCELERATE, THE VEHICLE DID NOT RESPOND. IT TOOK VARIOUS TRIES BEFORE IT WAS ABLE TO MOVE AND PLACED ON THE CURB. AFTER THAT THE VEHICLE STARTED TO RESPOND AGAIN BUT AT LIMITED SPEEDS AND WAS ABLE TO BARELY MADE IT BACK HOME AT VERY SLOW SPEEDS. IT WAS THEN TAKEN TO AN AUTO REPAIR SHOP AND IT WAS DETERMINED THAT THE TRANSMISSION WAS FAILING. IT HAS BEEN FURTHER DETERMINED THAT THERE IS A CONTAMINATION OF TRANSMISSION AND RADIATOR FLUIDS / COOLANTS AND A TOTAL TRANSMISSION FAILURE MAY BE POSSIBLE. THE VEHICLE HAS NOT BEEN IN OPERATION SINCE THIS WAS DISCOVERED AND WE ARE EVALUATING OPTIONS FOR REPAIR, UP TO AND INCLUDING TOTAL REPLACEMENT OF THE POWER-TRAIN AND RADIATOR. AFTER INVESTIGATING THIS POSSIBLE FAILURE I WAS ABLE TO FIND THAT THIS APPEARS TO BE A FAIRLY COMMON MANUFACTURER DEFECT BUT I CAN NOT FIND ANY RECALL NOTICES. THIS WAS A VERY DISTURBING INCIDENT AND THANKFULLY NO ONE WAS HURT, BUT THE TRANSMISSION FAILURE OCCURRING IN THE MIDDLE OF I-95 COULD HAVE RESULTED IN CRASH DUE TO THE SUDDEN DECELERATION OF THE VEHICLE. I'M LOOKING FOR GUIDANCE ON HOW THIS CAN BE TAKEN TO THE MANUFACTURER SO THEY CAN TAKE CARE OF THIS OBVIOUS FACTORY DEFECT. I LOOK FORWARD TO HEARING BACK FROM 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.
