THE DRIVER'S SIDE SEATBELT DOES NOT RETRACT CORRECTLY. I CONTACTED A LOCAL DEALERSHIP AND NISSAN AMERICA. THE DEALERSHIP GAVE ME AN ESTIMATE, WITHOUT SEEING THE TRUCK OF $100-$1500.00 TO REPLACE THE CURRENT SEATBELT. THIS IS A SAFETY ISSUE AND SHOULD BE FOR THE LIFE OF THE VEHICLE, NOT BASED ON THE MILAGE/AGE OF THE VEHICLE. I WILL CERTAINLY LET ALL KNOW ABOUT NISAAN'S LACK OF CONCERN FOR THE GENERAL PUBLIC WHICH CHOOSE TO PURCHASE THEIR CARS, NEW OR USED! NOT GOOD CUSTOMER SERVICE. I HAD A HONDA ACCORD THAT WAS 20+ YEARS OLD AND HONDA REPLACED THE SEATBELT AND ASSEMBLY FOR FREE, BEING IT WAS A SAFETY ISSUE!!!!!

WHILE TURNING TO GO UP HILL TOWARD HOME VEHICLE SUDDENLY DIED. LUCKILY NO ONE WAS BEHIND ME SO I PUT IT IN PARK AND AFTER HESITATION IT FINALLY RESTARTED. I TOOK TO DEALER,WALLACE NISSAN IN KINGSPORT, TENNESSEE AND THEY RAN CES CODE. THEY SUGGESTED HAVING RIGHT SIDE CAM SENSOR REPLACEMENT AND FLOAT IN GAS TANK WHERE IT HAS QUIT READING AT A COST OF APPROXIMATELY 700 TO 800 DOLLARS. CURRENTLY HAS NOT BEEN REPAIRED. PS : I PERFORMED THE BYPASS TO AVOID CROSS CONTAMINATION OF RADIATOR FLUID AND TRANSMISSION FLUID MYSELF AFTER READING OF ALL OF THE PROBLEMS THAT HAS CAUSED.THE TRANSMISSION HAS A SEPARATE COOLER; I DON'T KNOW WHY IT GOES THROUGH THE BOTTOM OF THE RADIATOR ANYWAY. CURRENT MILAGE IS 49,899 WHICH IS LOW MILES FOR A 2006 MODEL. A PERSON SHOULD NOT HAVE TO SURF THE WEB TO KNOW WHAT THEIR VEHICLE NEEDS WHEN NISSAN SHOULD BE NOTIFYING THEM. PEOPLE ARE PAYING FOR UNNECESSARY REPAIRS WHERE A SIMPLE RECALL COULD HAVE SAVED THEM THOUSANDS OF DOLLARS AND MORE IMPORTANTLY SOMEONE'S LIFE FROM AN ACCIDENT.

IN EARLY 2018 THE AIRBAG WARNING LIGHT BEGAN FLASHING. I BROUGHT MY VEHICLE IN TO MY CERTIFIED MECHANIC TO IDENTIFY THE ISSUE. THE ISSUE WAS DETERMINED TO BE THE RIGHT FRONT SEAT BELT ASSEMBLY. I AM TOLD THE ISSUE WITH THE SEAT BELT ASSEMBLY IMPACTS THE DEPLOYMENT OF THE AIRBAG AND THE MECHANISM THAT PREVENTS THE SEAT BELT FROM SPOOLING OUT WHEN AN ACCIDENT OCCURS. I HAD THE PART REPLACED ON MAY 29, 2018 BY MY CERTIFIED MECHANIC WITH A NISSAN OEM PART THAT CAME FROM LARRY MILLER NISSAN IN DENVER COLORADO. THE ISSUE WAS FIXED AND THE WARNING LIGHT WENT AWAY. SLIGHTLY MORE THAN 1 YEAR AFTER THE REPAIR, THE NEW PART FAILED. NISSAN WILL NOT STAND BY THEIR PART, THEY ONLY WARRANT IT FOR 1 YEAR, BUT I AM MORE CONCERNED THAT THERE IS SOMETHING WRONG WITH THE DESIGN OR MANUFACTURING OF THE PART. A SAFETY PART LIKE THIS SHOULD NOT FAIL, LET ALONE TWICE.

NISSAN IS RECALLING CERTAIN MODEL YEAR 2004-2006 ARMADA, TITAN, INFINITI QX56 AND MODEL YEAR 2005-2006 FRONTIER, PATHFINDER AND XTERRA VEHICLES. THE INTELLIGENT POWER DISTRIBUTION MODULE (IPDM) ASSEMBLY CONTAINS AN ENGINE CONTROL MODULE (ECM) RELAY THAT HAS A DIODE FOR ELECTRICAL CURRENT NOISE REDUCTION. 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 COULD CAUSE THE VEHICLE TO RUN OUT OF GAS AND STALL IN TRAFFIC, INCREASING THE RISK OF A CRASH.

Remedy: DEALERS WILL REPLACE THE FUEL LEVEL SENDING UNIT INSIDE THE FUEL TANK WITH A NEW ONE THAT HAS A MODIFIED FLOAT ARM. THIS SERVICE WILL BE PERFORMED FREE OF CHARGE. THE SAFETY RECALL IS EXPECTED TO BEGIN ON OR BEFORE MARCH 22, 2010. OWNERS MAY CONTACT NISSAN AT 1-800-647-7261.

DP26003 · Fuel Smell And Loss Of Motive Power

Opened Mar 30, 2026 · No close date supplied

Status: open (inferred from source dates) · Engine And Engine Cooling; Fuel System, Gasoline

The Office of Defects Investigation (ODI) received a Petition dated February 5, 2026, requesting an investigation into model year (MY) 2006 Nissan Frontier vehicles. The Petitioner alleges that the vehicle poses an imminent fire hazard due to “[a] powerful and persistent odor of raw gasoline” that he says “emanates from the vehicle” and “indicat[es] a breach in fuel system integrity.” He further alleges that the vehicles can experience sudden engine stalling “during startup and operation,” which he believes could cause collisions or loss of vehicle control. The Petitioner further alleges these symptoms are identical to conditions addressed in previous NHTSA recalls (10V-517, 07V-435, and 10V-075) and that the issues persist in the 2006 MY Nissan fleet despite these past actions. ODI is opening this Defect Petition to evaluate the Petitioner’s allegations and determine whether to grant or deny the Petition.  The Petition can be viewed at NHTSA.gov under NHTSA Number 11718552.

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.
