ABOUT 2 WEEKS AGO I STARTED TO FEEL AS IF THE TRUCK WAS NOT SHIFTING CORRECTLY, SOON AFTER THAT THE CHECK ENGINE LIGHT CAME ON AND I BROUGHT IT RIGHT IN TO OUR REGULAR SERVICE STATION. A DIAGNOSTIC CHECK REVEALED CODE P0717 FOR A TURBINE REVOLUTION SENSOR AND I WAS TOLD TO TAKE IT TO THE DEALER. THE NISSAN DEALER DID THEIR OWN DIAGNOSTIC (NO TEST DRIVE) AND FOUND IT TO BE A BAD VALUE BODY, AS WELL AS BAD TIMING CHAIN AND TENSIONERS, AND REPLACEMENT OF ALL 6 COIL PACKS, ALONG WITH A FEW OTHER GENERAL FINDINGS GAVE ME AN ESTIMATE OF NEARLY 5 THOUSAND DOLLARS. THE 2 DIAGNOSTIC CHECKS HAVE COST ME CLOSE TO $250. I WAS IN SHOCK AND DID NOT HAVE THE ABILITY TO PAY FOR THE REPAIRS UP FRONT, SO I TOOK THE TRUCK TO 2 OTHER SERVICE STATIONS, ONE BEING AAMCO WHO SPECIALIZES IN TRANSMISSIONS. NONE OF THE 3 OTHER STATIONS FOUND ANY OTHER ISSUES ASIDE FROM THE TRANSMISSION. AAMCO AFTER A TEST DRIVE AND DIAGNOSTIC CHECK DETERMINED THERE WAS AN ISSUE BUT WOULD NEED TO REMOVE THE TRANSMISSION TO DETERMINE THE EXTENT OF THE PROBLEM. AAMCO FOUND THERE TO BE WATER BEING PUMPED INTO THE TRANSMISSION, AND ALSO CLAIMED IT WAS THE 3 PROBLEM OF THIS TYPE THEY HAD SEEN SO FAR THIS MONTH. APPARENTLY THE RADIATOR LEAKS WATER INTO THE TRANSMISSION. THE FIX IS A REBUILT TRANSMISSION AND SEPARATE COOLER FOR THE TRANSMISSION TO ASSURE THIS WON'T HAPPEN AGAIN. AT A COST OF 3200 TO ME! THIS PARTICULAR AAMCO IS ACROSS FROM THE DEALER AND CLAIMS THAT HAVE DONE WORK FOR THE DEALERSHIP TO FIX THE SAME PROBLEM! I ALSO RECEIVED A LETTER BACK IN OCT. /NOV. INDICATING A POSSIBLE RADIATOR PROBLEM AND AN OFFER OF AN EXTENDED WARRANTY. NOTHING WAS MENTIONED OF THE DAMAGE THAT COULD OCCUR TO THE TRANSMISSION! I FEEL CHEATED, AND IN MY RESEARCH HAVE FOUND THIS TO BE A VERY COMMON PROBLEM. NISSAN SHOULD STAND BY THEIR PRODUCT AND DO THE RIGHT THING BY THEIR CUSTOMERS! *TR

WHILE I HAVE NOT YET HAD A FAILURE, OR CRASH I HAVE BEEN NOTIFIED BY NISSAN THAT MY TRUCK'S TRANSMISSION MAY FAIL SUDDENLY MAKING THE VEHICLE INOPERABLE. THIS IS A CONCERN AS I OCCASIONALLY USE THE VEHICLE FOR COMMUTING TO WORK ON THE INTERSTATE HIGHWAY SYSTEM AND FEAR I WOULD BE SUBJECT TO INJURY OR DEATH IF I HAVE A SUDDEN FAILURE AND THERE IS NO PLACE TO PULL SAFELY OFF THE ROAD. I ALSO USE THE TRUCK TO GO DEEP INTO THE MAINE WILDERNESS TO FISH AND HUNT AND FEAR IF THE TRANSMISSION FAILS, I COULD BE STRANDED DOZENS OF MILES FROM THE NEAREST HELP, PUTTING MY HEALTH AND SAFETY AT RISK. *TR

I WAS DRIVING ON THE INTERSTATE IN OVERDRIVE AND THE TRUCK CAME OUT OF GEAR AND THE ENGINE REVVED HIGH IN RPMS. I HAD TO TURN OVERDRIVE OFF TO GET THE TRUCK TO DRIVE IN 4TH GEAR. I TOOK THE TRUCK TO A TRANSMISSION SHOP AND THEY EXPLAINED COOLANT FROM THE RADIATOR HAD GOTTEN INTO THE TRANSMISSION. THEY EXCHANGE THE FLUID BUT EXPLAINED THE TRANSMISSION MAY NEED TO BE REBUILT IF A LOT OF DAMAGE HAS BEEN DONE. I WAS ABLE TO DRIVE IT FOR A WEEK MORE SHIFTING NORMALLY. I CAME TO A STOP AT A RED LIGHT AFTER A WEEK AND WHEN PRESSING THE GAS THE TRUCK WOULD BARELY CREEP FORWARD THROUGH THE INTERSECTION. WHEN THE TRUCK WAS TURNED OFF IT WOULD NOT CRANK BACK UP AND IT IS CURRENTLY IN THE TRANSMISSION SHOP WAITING FOR PARTS BECAUSE OF A SHORTAGE OF NEEDED PARTS DUE TO THE PERVASIVENESS OF THIS ISSUE. *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.
