I STARTED NOTICING MY AUTOMATIC NISSAN FRONTIER HAVING PROBLEMS SHIFTING GEARS AROUND NOVEMBER OF 2012. I EVENTUALLY TOOK THE TRUCK INTO A DEALERSHIP TO TAKE A LOOK AT IT AFTER RECEIVING PAPERWORK IN REGARDS TO A LAWSUIT NISSAN IS ENCOUNTERING DUE TO RADIATOR LEAKS. WHEN I TOOK THE TRUCK INTO THE DEALER THEY TOLD ME THIS DID NOT HAVE ANYTHING TO DO WITH RADIATOR LEAK. THEY QUOTED ME 5,000 IN REPAIRS. I DID NOT HAVE THE MONEY TO FIX THE PROBLEM SO I CONTINUED TO DRIVE IT UNTIL JULY 12TH IT FINALLY GAVE OUT. I WAS GETTING OFF OF THE FREEWAY AND AS I WAS STOPPING AT THE RED LIGHT TO GET OFF OF THE FREEWAY THE TRUCK STARTED TO FEEL LIKE IT WAS GOING TO GIVE AND IT STARTED SHAKING, IT JERKED SUDDENLY AND ALMOST CAUSED THE CAR BEHIND ME TO CRASH INTO MY BUMPER, I PUT A LITTLE MORE GAS INTO THE TRUCK AND MADE IT INTO THE PARKING LOT OF THE NEAREST PLACE AROUND. AS I WAS GOING TO PARK IT FINALLY GAVE OUT FOR GOOD. I CALLED A LOCAL TOWING COMPANY AND THEY TOOK THE CAR BACK MY HOUSE, I CALLED UP A MECHANIC TO COME TO THE HOUSE AND EXAMINE THE TRUCK AND HE ADVISED ME OF THE RADIATOR LEAK, THE ONE THE NISSAN DEALERSHIP DENIED HAVING. I AM VERY UPSET THAT THEY LIED TO ME AS WELL AS NISSAN ONLY EXTENDING THE WARRANTY TO 80,000 MILES WHEN MOST PEOPLE ARE EXPERIENCING THIS PROBLEM AFTER THAT. I HAVE APROX 118,000 MILES, I WILL LOOK FOR A LAWYER TO FILE A CLASS ACTION LAWSUIT AGAINST NISSAN. *TR

MY 2005 FRONTIER HAS NEVER GIVEN ME ANY PROBLEMS UNTIL 2 DAYS AGO. THE TRANSMISSION STARTED MESSING UP. I CAME UPON A 4 WAY STOP & WHEN I WENT TO CROSS THE ROAD IT WAS LIKE I HAD IT IN NEUTRAL. I PULLED OVER & STOPPED THEN TRIED TO START AGAIN & IT DID THE SAME THING. I'VE SINCE HEARD & READ ABOUT ALL THE PROBLEMS INVOLVING THE COOLANT & TRANSMISSION. THE QUOTES I HAVE RECEIVED TO FIX THIS ARE OUTRAGEOUS. NISSAN SHOULD RECALL THESE VEHICLES BECAUSE THEY KNOW THEY HAVE A PROBLEM WITH THEM. NOT A HAPPY CUSTOMER ANYMORE. *TR

MY TRUCK BEGAN DISPLAYING SYMPTOMS OF CATASTROPHIC TRANSMISSION FAILURE. FOR EXAMPLE, GEAR SLIPPAGE AND SHUDDERING AS IF ROLLING OVER RUMBLE STRIPS. I TOOK IT TO A MECHANIC AND THEY FOUND THE COOLANT HAD TRANSFORMED INTO A THICK PINK SUBSTANCE. IT WAS DETERMINED THAT A SEAL HAD FAILED IN THE RADIATOR CAUSING COOLANT TO MIX WITH THE TRANSMISSION FLUID. THIS THEN BAKED INSIDE THE TRANSMISSION. WE REPLACED THE RADIATOR AND SO FAR HAVE DELAYED THE INEVITABLE REPLACEMENT OF THE TRANSMISSION. I CALLED LOCAL NISSAN DEALERSHIPS AND THEY KNOW ABOUT THE PROBLEM BUT DECLINED TO OFFER SIGNIFICANT INFORMATION. I CONTACTED NISSAN AND BECAUSE OF LANGUAGE BARRIERS, ETC., THEY WOULD NOT ADDRESS MY ISSUE. I CONTACTED THE BBB AND A NISSAN REPRESENTATIVE EVENTUALLY CALLED ME, BUT IN THE END DISREGARDED MY ISSUES WITH MOCK CONCERN. I CONTACTED THE MN ATTORNEY GENERAL AND THEY SAID I MIGHT TAKE THEM TO SMALL CLAIMS COURT. IT SEEMS THAT NISSAN HAS CONCOCTED A WARRANTY THAT ONLY BENEFITS PEOPLE WHO EXPERIENCE THE PROBLEM AT A VERY PREMATURE STAGE. *TR

JUST BOUGHT AN 05' NISSAN FRONTIER AND UPON GETTING ONTO A HIGHWAY I SPED UP TO 55-60MPH TO FEEL A VIBRATION LIKE GOING OVER SPEED BUMPS AND A LOSS OF POWER. IT TURNS OUT THAT THE INTERCOOLER FROM THE RADIATOR BROKE INSIDE THE TRANSMISSION CAUSING A LEAK OF ANTIFREEZE INSIDE THE TRANSMISSION. WHICH CAUSED SOMETHING IN THE TRANSMISSION TO BREAKDOWN. I AM NOT VERY PROFICIENT IN CAR REPAIR SO I AM NOT SURE THE EXACT PART THIS CAUSES TO MALFUNCTION INSIDE THE TRANSMISSION. ALL I KNOW IS THAT I NEED A BRAND NEW TRANSMISSION AND RADIATOR WHICH IS GOING TO CAUSE $6000.00 AT LEAST. I ALSO KNOW THAT THIS IS A WIDESPREAD THING AND A LOT OF PEOPLE ARE HAVING THIS HAPPEN TO 05-10 NISSAN FRONTIERS, XTERRAS AND PATHFINDERS. THIS SEEMS LIKE A SAFETY ISSUES; IF I'M ON A HIGHWAY WITH MY FAMILY AND TRY TO PASS SOMEONE AND EXPERIENCE A LOSS OF POWER TO SPEED UP TO PASS THEM I COULD GET IN A HEAD ON COLLISION. *TR

EXPERIENCED SUDDEN JERKING WHEN TRAVELING AT HIGHWAY SPEEDS. THE PROBLEM WAS DIAGNOSED AS A FAILED TRANSMISSION COOLER WHICH ALLOWED COOLANT TO MIX WITH THE TRANSMISSION FLUID, CAUSING INTERNAL DAMAGE TO THE RADIATOR AND TRANSMISSION. PRIOR TO THIS, THERE WAS NOTHING AMISS WITH THE OPERATION OF THE VEHICLE. APPARENTLY THIS IS COMMON AND EVEN THOUGH SEVERAL COMPLAINTS HAVE BEEN FILED TO NHTSA, NISSAN STILL CLAIMS THAT THERE IS NO DEFECT. BASED ON THE NUMBER OF COMPLAINTS REGARDING THE EXACT SAME ISSUE, PLEASE CONSIDER ISSUING A RECALL. I JUST BOUGHT MY TRUCK IN DEC. 2012 WITH ABOUT 81,000 MILES AND 4 MONTHS AND 2,000 MILES LATER, I AM ON THE HOOK FOR THIS DEFECT. *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.
