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

TO WHOM IT MAY CONCERN: I OWN A 2005 NISSAN FRONTIER SE. ON SATURDAY, JUNE 15, 2013 THE VEHICLE FAILED WHILE I WAS APPROACHING AN OVERPASS IN A DOWNPOUR OF THUNDERSTORMS. IT APPEARED THE VEHICLE'S TRANSMISSION FAILED. I HAD TO STEER MY VEHICLE OFF THE ROAD AS THE TRANSMISSION SEEMED TO HAVE SLIPPED INTO NEUTRAL. THANKFULLY, NO INJURY OR ACCIDENT OCCURRED. AFTER SPEAKING WITH A NISSAN OF NORTH AMERICAN CUSTOMER SERVICE REPRESENTATIVE, I HAD IT TOWED INTO PAT FISHER NISSAN IN TITUSVILLE ON MONDAY MORNING, JUNE 17TH. IN THE MEANTIME AFTER RESEARCHING ON THE INTERNET (WWW.NISSANHELP.COM), I LEARNED NISSAN IS IN LITIGATION DUE TO A 'DESIGN FLAW' IN THE RADIATOR; CAUSING CROSS CONTAMINATION OF FLUIDS (RADIATOR TO TRANSMISSION) RESULTING IN MAJOR DAMAGE TO THE VEHICLE. THIS RESULTS IN REPLACING THE RADIATOR AND HAVING THE ENGINE FLUSHED ($1097.00); AND AN ADDITIONAL FEE ($4524.00) FOR REPLACING THE TRANSMISSION. AFTER A CLASS ACTION LAW SUIT, NISSAN HAS AGREED TO PAY PARTIAL PAYMENT FOR THE REPAIRS IF YOUR VEHICLE FALLS UNDER THEIR SPECIFIC GUIDELINES (YEAR OF VEHICLE AND ODOMETER READING). UNFORTUNATELY, MY VEHICLE DID NOT. MY CONCERN: SINCE THIS MALFUNCTION IS A 'DESIGN FLAW' (TOLD THIS BY A NISSAN EMPLOYEE) BY THE MANUFACTURER, HOW DO CUSTOMERS GET NISSAN OF NORTH AMERICA TO ACCEPT RESPONSIBILITY? THERE SHOULD BE NO LIMITATIONS OR GUIDELINES TO MEET. ALL VEHICLES WITH THIS PROBLEM SHOULD BE REPAIRED BY NISSAN OF NORTH AMERICA BEFORE DEATH OR A SERIOUS ACCIDENT OCCURS. THIS IS A SAFETY ISSUE. THE VEHICLE SHIFTS ITSELF INTO NEUTRAL WHILE ENGAGED IN DRIVE. THIS SHOULD BE A SAFETY RECALL AND THE EXPENSE OF REPAIR BE REIMBURSED BY NISSAN OF NORTH AMERICA CORPORATION TO THE CONSUMER. THANK YOU FOR YOUR CONSIDERATION AND REVIEW. I LOOK FORWARD TO A RESPONSE. SINCERELY *TR
