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
