I HAD 1/4 OF A TANK OF GAS AND WENT TO FILL UP. AFTER FILLING UP MY GAS TANK, I TURNED ON THE CAR, AT WHICH POINT THE NEEDLE DID NOT REGISTER THE FULL TANK. AFTER DRIVING A COUPLE MILES, THE CHECK ENGINE LIGHT CAME ON. I WENT DIRECTLY TO THE DEALER AND WAS TOLD THAT IT WAS A FUEL SENDING UNIT/SENSOR AND THAT IT WAS NO LONGER COVERED AFTER 30K MILES. AFTER RETURNING HOME AND DOING RESEARCH, I WENT ONLINE TO X.NISSANHELP.COM AFTER PERFORMING A SEARCH, I CAME ACROSS MANY OTHERS WHO HAVE EXPERIENCED THE SAME PROBLEM. APPARENTLY IT HAS SOMETHING TO DO WITH THE FUEL SENDING UNIT. A SIMILAR PROBLEM WAS FOUND ON THE 2000-2004 XTERRA MODELS AND A RECALL WAS PERFORMED WHEN THE VEHICLE WOULD STOP AFTER NOT GETTING ANY FUEL, POSING A GREAT DANGER. IT SEEMS THAT SOMETHING IN THE UNIT IS FAULTY AND WILL CORRODE OVER TIME. THERE IS A GENERAL CONSENSUS THAT EVERYONE WHO IS HAVING THE PROBLEM IS EXPERIENCING THE SAME THING AFTER HAVING THE VEHICLE FOR OVER 2 YRS AND WITH AROUND 39K-49K. IF THIS PROBLEM EXISTED IN PREVIOUS MODELS, AND IT WAS RECALLED, THE 2005-2007 XTERRAS, FRONTIERS, AND PATHFINDERS SHOULD GET THIS FIXED AT NO CHARGE TO THE CUSTOMER!! WHY WAIT FOR ACCIDENTS AND POSSIBLE DEATHS, ESPECIALLY SINCE THE PROBLEM LIES IN AN INTEGRAL PART OF THE VEHICLE. COST OF REPAIR RANGES FROM $300-600." I'VE COPIED THIS COMPLAINT FROM ANOTHER OWNER BECAUSE IT'S VERY ACCURATE AND WELL WORDED. IT'S UNSAFE FOR SOMEONE TO BE STRANDED IN THE MIDDLE OF NOWHERE BECAUSE THEY RUN OUT OF GAS BECAUSE OF A DEFECTIVE PART. IT'S UNSAFE TO RUN OUT OF GAS EXECUTING A MANEUVER AT AN INTERSECTION. PLEASE HELP US. *TR

THE SERVICE ENGINE SOON LIGHT HAS NOW STARTED COMING ON. THE PROBLEM STARTED AT RIGHT AROUND 36,000 MILES. OF COURSE THIS PROBLEM IS NOT WARRANTED AFTER 36K. MY TRUCK HAS 39,000 MILES ON IT. I WENT TO THE DEALER THIS PAST FRIDAY AND THEY WANT 330.00 TO FIX IT. THE CASHIER AT SERVICE DESK AT NISSAN ADMITTED THAT IT IS A PROBLEM FOR THE XTERRA'S AND THE PATHFINDER SUVS. SHE ALSO SAID IF I DON'T FIX IT IMMEDIATELY, IT WONT AFFECT THE VEHICLE ACTUALLY RUNNING. I DECIDED TO SEE JUST HOW TRUE THIS WAS AND I AM SURPRISED TO SEE JUST HOW MANY OTHERS HAVE THE SAME STORY AT AROUND THE SAME MILEAGE. *TR

I HAVE CHECKED GAS USED AGAINST ODOMETER MILEAGE AND IT SEEMS CORRECT -- SO NO LEAKS! DEALERS HAVE BEEN CALLED BUT NO IDEAS, AND IT HAS NOT BEEN TAKEN IN FOR THIS COMPLAINT YET.

THE ECM RELAY MAY ALLOW SILICON VAPOR TO FORM AND, OVER TIME, THE SILICON EVAPORATES FROM THE DIODE MOLDING WHICH CAUSES SILICON OXIDE TO DEVELOP ON THE ECM RELAY CONTACT DUE TO ARCING.

Consequence & remedy

Consequence: THIS COULD CAUSE ENGINE STALLING INCREASING THE RISK OF A CRASH.

Remedy: DEALERS WILL REPLACE THE ECM RELAY INSIDE THE IPDM ASSEMBLY. THIS SERVICE WILL BE PERFORMED FREE OF CHARGE. THE SAFETY RECALL BEGAN ON DECEMBER 6, 2010. OWNERS MAY CONTACT NISSAN AT 1-800-647-7261.

Consequence & remedy

Consequence: THIS ISSUE COULD RESULT IN THE NON-DEPLOYMENT OF THE DRIVER AND PASSENGER FRONT AIR BAGS IN A CRASH, INCREASING THE RISK OF PERSONAL INJURY.

Remedy: DEALERS WILL REPLACE THE FRONT CZS WITH A REDESIGNED SENSOR. THE RECALL BEGAN ON JANUARY 26, 2009.
