SOON AFTER PASSING THE 103,000 MILE MARK IN OCTOBER, 2015, MY 2005 FRONTIER 'S AUTOMATIC TRANSMISSION (WITH THE V-6 ENGINE) STARTED SHUTTERING WHEN I PRESSED THE ACCELERATOR WHILE THE CAR WAS GOING 62 TO 65 MPH. IT WAS QUITE STARTLING AND WORRISOME. THE PROBLEM SLOWLY GOT WORSE WITH SHUTTERING OCCURRING AT DIFFERENT SPEEDS AND UNDER DIFFERENT LOADINGS. WITHIN A WEEK OR TWO, I TOOK IT INTO A NATIONAL TRANSMISSION REPAIR STORE (AMACO) WHO WANTED TO CHARGE ME $180 FOR 2 HOURS OF DIAGNOSIS TO FIND OUT WHAT THE PROBLEM WAS. I ENDED UP PAYING THEM FOR ONLY 1 HOUR OF THEIR TIME. THEY SAID I HAD WATER IN MY TRANSMISSION AND THAT IT WOULD NEED TO BE REBUILT TO THE TUNE OF AROUND $5,000! THEY SAID I'D NEED TO REPLACE AN INTERNAL COMPUTER...ALONG WITH THE COST TO REBUILD THE TRANSMISSION. WHAT MAKES ME MAD IS THAT I TOOK THE CAR TO AMACO AT AROUND THE 90,000 MILE MARK (IN 2014) TO GET SOME MAJOR TRANSMISSION WORK DONE THAT TURNED OUT TO BE A MALFUNCTIONING ELECTRONIC/COMPUTER PART IN THE TRANSMISSION. THIS COST ME AROUND $1,600 TO FIX. AT THAT POINT, THERE WAS NO WATER IN THE TRANSMISSION. HOWEVER, THEY SHOULD HAVE INFORMED ME I SHOULD REPLACE THE RADIATOR AT THAT POINT BECAUSE THE RADIATORS WERE FAILING AND WOULD REQUIRE THE TRANSMISSION BE REBUILT. THE REPAIR SHOP COULD HAVE INFORMED ME OF THE PROBLEM NISSAN WAS HAVING WITH THE RADIATOR...BUT CHOSE NOT TO TELL ME. I COULD HAVE FIXED THE POTENTIAL RADIATOR PROBLEM FOR AROUND $300, BEFORE IT CREATED THE EVENTUAL TRANSMISSION FAILURE WHICH COST $5,000. NISSAN ALSO KNEW, BUT CHOSE NOT TO ADVISE ME TO REPLACE THE DEFECTIVE RADIATOR BEFORE IT FAILED. THE DEALER'S FAILURE TO NOTIFY ME ABOUT THE RADIATOR DESIGN FLAW, WHICH THEY KNEW ABOUT IT IN 2007, KEPT ME FROM REPLACING IT. I WOULD HAVE GLADLY DONE THIS TO AVOID SPENDING $5,000 WHEN THE RADIATOR FAILED. THE ESTIMATED "DATE THIS HAPPENED" IS 9/14/2015.

THERE WAS A CLASS ACTION LAWSUIT SETTLEMENT ALLEGING NISSAN NORTH AMERICA CONCEALED FROM CONSUMERS A CROSS-CONTAMINATION OF ENGINE COOLANT AND TRANSMISSION FLUID FOR 2005-2010 FRONTIERS. ON JUNE 18, 2015 MY TRUCK LOST POWER AND STOPPED WORKING, IN THE MIDDLE OF AN INTERSECTION, ALMOST CREATING AN ACCIDENT. I TOWED MY TRUCK TO GET IT REPAIRED, I PAID $120 AND $1800, THEY FIXED HALF OF THE PROBLEM. SINCE MY TRUCK WAS STILL NOT WORKING I DID SOME RESEARCH AND FOUND OUT ABOUT THE EXTENDED WARRANTY. I TOWED MY TRUCK TO BUENA PARK NISSAN WHERE I HAD TO PAY $3000 TO FIX MY TRUCK. I CONTACTED NISSAN NA TO SEE IF I COULD GET A REFUND FOR COST I HAD ALREADY MADE, THEY TOLD ME TO SEND THEM INVOICES OF WHAT I HAD PAID. LATER THEY SAID THAT THEY COULD NOT REIMBURSE ME SINCE IT WAS NOT REPAIRED AT A NISSAN DEALERSHIP. I HAVE PAID A TOTAL OF $4920 FOR A PROBLEM NISSAN CREATED, KNEW ABOUT AND CONCEALED FROM CUSTOMERS.

CHECK ENGINE LIGHT CAME ON, GOT SCANNED AT AUTO ZONE, ALL CODES REFERENCED TRANSMISSION & SENSORS (I.E. CAM SHAFT)...TOOK TO GEURLICH'S AUTO FOR AN INSPECTION AND TRANSMISSION WAS SUGGESTED TO BE REPLACED...TOOK IT TO AAMCO FOR AN INSPECTION/2ND OPINION AND SAME DIAGNOSIS, REPLACE/RE-BUILD TRANSMISSION. FINALLY ACCUMULATED THE FUNDS TO HAVE A MECHANIC REBUILD OUR TRANSMISSION AND UPON RETURN OF OUR VEHICLE, AND UNBEKNOWNST TO US, HE MENTIONED THE KNOW ISSUES/INVESTIGATION STEMMING BACK TO 2012 WITH THE RADIATOR LEAKING INTO THE TRANSMISSION AND CAUSING IT TO FAIL, WHICH IS ULTIMATELY WHAT HE FELT HAPPENED. SINCE WE PURCHASED THE VEHICLE ON 08/08/2012 WITH AN ODOMETER READING OF 100,340. WE WOULD HAVE BEEN ENTITLED TO NONE OF THE REPAIR OPTIONS OR CONCESSIONS NISSAN OFFERED UNDER THE PROPOSED CLASS ACTION, SINCE ALL WERE OFFERED ONLY UP TO 100K MILES. THE DATE THE INVESTIGATION WAS OPENED ACCORDING TO HTTP://WWW-ODI.NHTSA.DOT.GOV/ WAS 6/11/2012, 2 MONTHS PRIOR TO OUR PURCHASE. THE DEALER AT THE TIME SHOULD HAVE BEEN WELL AWARE OF THE OPEN INVESTIGATION AND PROVIDED US INFORMATION ON IT SO THAT WE MAY HAVE MADE A MORE INFORMED DECISION. I FEEL THAT THIS PURCHASE, ALTHOUGH 3 YEARS POST PURCHASE, FALLS WITHIN THE LEMON LAW STATUTES AND WARRANTS REIMBURSEMENTS TO US OF THE COST TO RE-BUILD THE TRANSMISSION, REPLACE RADIATOR, ETC.

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.
