FOR THE PAST WEEK WHEN EVER I DROVE MY CAR THE ENTIRE VEHICLE SHUDDERS, SHAKES AND HAS A HARSH UPSHIFT WHEN IT IS CHANGING GEARS. IT HAPPENS THE MOST ON HIGHWAYS GOING AT HIGH SPEEDS (55-65 MILES). I TOOK MY CAR INTO A NISSAN DEALERSHIP ON 1-29-14 TO GET IT CHECKED OUT. THE DEALERSHIP DIAGNOSED MY CAR WITH A "BROKEN TRANS COOLER LINE IN RADIATOR WHICH MADE THE COOLANT LEAK AND MIXED WITH TRANSMISSION FLUID. ADVISE REPLACE ENTIRE TRANSMISSION, RADIATOR, AND FLUSH ENGINE BLOCK AS WELL AS REPLACE THERMOSTAT, (PRICE TO FIX: $5938.00 + 9% TAX)". I RESEARCHED THIS ISSUE ONLINE AND FOUND THIS TO BE A COMMON DEFECT ISSUE THAT NISSAN HAS BEEN DANCING AROUND SINCE 2007, AS WELL AS A CLASS ACTION LAWSUIT BEING FILED AGAINST NISSAN. I BOUGHT THE CAR ON JULY 28, 2011, SO I HAVE ONLY OWNED THE CAR FOR A LITTLE OVER 2 YEARS IN WHICH THE DEALERSHIP I PURCHASED THE CAR FROM DID NOT INFORM US OF THIS WARRANTY BEING OFFERED BY NISSAN FROM THE LAWSUIT OR INFORMED US OF THE POSSIBLE TRANSMISSION PROBLEM. I HAD THE CAR COMPLETELY CHECKED OUT BY A MECHANIC IN NOVEMBER OF 2013 AND IT PASSED WITH NO ISSUES. NOW HERE WE ARE 2 MONTHS LATER, AND OVER 100,000 MILES AND MY NISSAN EXPERIENCES THIS ISSUE. THIS CAN BE A VERY DETRIMENTAL AND DRAMATIC FAILURE, CAUSING MASSIVE SAFETY ISSUES IF I CONTINUE TO DRIVE MY CAR, ESPECIALLY ON HIGHWAYS GOING HIGH SPEEDS. I CONTACTED NISSAN THIS MORNING TO SEE IF THEY ARE GOING TO STAND BEHIND THEIR PRODUCT AND SINCE I AM ONLY 11,000 MILES OVER THEIR "WARRANTY" (WHICH HAS HIGH DEDUCTIBLES), THEY DENIED TO HELP AND I AM LEFT HOLDING A $6500.00 PRICE TAG TO FIX MY CAR. *TR

I REQUEST THAT THE DOT NHTSA INVESTIGATE MANUFACTURER DEFECTS IN 2007 NISSAN PATHFINDERS COOLING SYSTEM AND TRANSMISSION AS UNEXPECTED FAILURE RELATES TO DRIVER SAFETY. MY 2007 PATHFINDER WITH 90,000 MILES CAUSED A MAJOR COLLISION WITH A DEER AS THE TRANSMISSION BEGAN TO FAIL. DRIVING HOME, AT AROUND 40MPH, UP A HILL (ENGINE UNDER LOAD @ 2,200-2,500 RPM) THE WHOLE CAR BEGAN SUDDENLY TO "SHUDDER"- SIMILAR TO THE FEELING/ SOUND OF RIDING OVER HIGHWAY RUMBLE STRIPS. THIS RESULTED IN A LOSS OF CONTROL OVER THE SPEED OF THE VEHICLE AND A NOTICEABLE DISTRACTION LEAVING ME UNPREPARED AS A LARGE BUCK RAN OUT FROM THE TREE LINE ATTEMPTING TO CROSS THE ROAD- THE BUCK DID NOT MAKE IT ACROSS. AS I HAVE FOUND IN MY RESEARCH AFTERWARDS, THERE IS A WIDELY KNOWN MANUFACTURER DEFECT IN WHICH ENGINE COOLANT MIXES WITH TRANSMISSION FLUID. THE RESULTING "GOOP" SHREDS THE INTERNAL PARTS OF THE TRANSMISSION RENDERING IT (ALONG WITH THE RADIATOR AND COMPONENTS) COMPLETELY USELESS. THESE VEHICLES ARE UNSAFE FOR THE ROADWAYS AS THIS PROBLEM OCCURS SUDDENLY AND UNEXPECTEDLY WITHOUT WARNING. I CONSIDER MYSELF LUCKY FOR BEING ALIVE- NOW, BUT SINCE NISSAN NOR ANY OTHER ORGANIZATION IS WILLING TO RECALL OR REPLACE THIS VEHICLE/ AFFECTED PARTS, I AM STUCK, FORCED TO DRIVE ON THE ROAD BEING A HAZARD TO OTHERS AND MYSELF. *TR

THE TRUCK BEGAN SHIFTING GEARS VERY ROUGHLY AND SLOWLY WITH A STRONG JERKING MOTION TO THE TRUCK. WHEN TAKEN FOR DIAGNOSIS WAS TOLD THAT THE TRANSMISSION FLUID AND COOLANT WERE MIXING DUE TO A FAULTY RADIATOR AND THUS GOT INTO TRANSMISSION CAUSING THE NEED FOR REPLACEMENT OF RADIATOR, FLUSHING OF FLUID LINES AND TRANSMISSION REPLACEMENT APPROX. COST $6000. AFTER RESEARCHING THIS PROBLEM, I SEE MULTITUDES OF OTHER NISSAN CUSTOMERS HAVE HAD THE SAME PROBLEM. THIS ISSUE IS EXTREMELY UNSAFE ON ROADS. MY CAR FALLS OUTSIDE THE EXTENDED WARRANTY GIVEN DUE TO THIS PROBLEM. IN ADDITION, IF MY PATHFINDER DID FALL UNDER THE WARRANTY, NISSAN ONLY ASSISTS WITH PAYMENT TO REPLACE RADIATOR NOT THE DAMAGE DONE TRANSMISSION BECAUSE OF THE FAULTY RADIATOR. THIS ABSOLUTELY NEEDS TO BE INVESTIGATED FURTHER! *TR

VEHICLE BEGAN TO VIBRATE AT SPEEDS OF APPROX 45 MPH. OVER A SHORT PERIOD OF TIME, THE CONDITION WORSENED - THE VIBRATIONS BECAME MORE AGGRESSIVE AND BEGAN TO OCCUR AT HIGHER SPEEDS. AFTER INVESTIGATION BY NISSAN, THEY ADVISED THAT THERE WAS AN ISSUE WITH THE RADIATOR AND POSSIBLY TRANSMISSION THAT WAS NO LONGER UNDER WARRANTY BECAUSE I WAS OUTSIDE OF THE 100,000 MILE LIMIT. THE COOLANT IS LEAKING INTO THE TRANSMISSION FLUID COOLER LINE AND ULTIMATELY RIGHT INTO THE TRANSMISSION, THEREBY CAUSING DAMAGE THAT MAY OR MAY NOT BE REPAIRED WITH A NEW RADIATOR AND TRANSMISSION. APPARENTLY, THIS IS A KNOW ISSUE WITH THESE VEHICLES AND NISSAN NEGLECTED TO ALERT CONSUMERS. AT THIS TIME, THE VEHICLE IS INOPERABLE. *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.
