I WAS DRIVING ON A MAJOR HIGHWAY WHEN ALL OF A SUDDEN THE AUTOMATIC TRANSMISSION DOWNSHIFTED INTO SECOND GEAR. THE FRONTIER IMMEDIATELY SLOWED DOWN. I WAS DRIVING IN FRONT OF A TRACTOR TRAILER AND JUST MISSED GETTING REAR ENDED. I'VE SINCE FOUND OUT THAT NISSAN HAS BEEN AWARE OF THE RADIATOR LEAKING AND CROSS CONTAMINATING WITH THE TRANSMISSION FLUID AND BLOWING OUT THE TRANSMISSION. THIS IS A DANGEROUS SITUATION WITH THESE VEHICLES INVOLVED AND NISSAN SHOULD BE RESPONSIBLE FOR CORRECTING THEIR DEFECT REGARDLESS OF VEHICLE MILEAGE. THIS VEHICLE NEEDS TO BE RECALLED AND FIXED. *TR

AND THIS BULL CRAP. NISSAN NEEDS TO MAN UP AND STAND BEHIND THERE VEHICLES. DISSATISFIED CUSTOMERS CAN SPREAD THE WORD. NEVER BUY A NISSAN. *TR

LAST TIME I CHANGED MY OIL ABOUT A MONTH AGO, THEY WERE CONFUSED AT WHY I HAD OIL IN MY RADIATOR. THEY SAID IT WAS NOT A GOOD SIGN! YESTERDAY WHEN I WAS DRIVING TO WORK, MY TRUCK HAD NO POWER AND IT EVENTUALLY STOPPED MOVING IN THE ROAD. THE TRUCK WAS RUNNING, BUT WOULD NOT ENGAGE IN A GEAR AND MOVE FORWARD. I HAD IT TAKEN TO A LOCAL SHOP TO LOOK IT OVER AND AFTER A TEST DRIVE AND LOOKING AT THE TRANSMISSION AND RADIATOR FLUIDS, THEY SAID I HAD A CROSS CONTAMINATION OF THE TWO SYSTEMS AND IT CAUSED THE PROBLEM. THEY CALLED THE NISSAN DEALER AND THEY SAID THIS IS A COMMON PROBLEM AND THEY HAVE A LAW SUIT I CAN JOIN TO GET REIMBURSED FOR THE EXPENSE OF REPLACING THE CVT. (CONTINUOUSLY VARIABLE TRANSMISSION) IT WILL COST ABOUT $4,200. I LOOKED ONLINE AND IT LOOKS LIKE NISSAN ALSO HAS AT CVT REPLACEMENT PROGRAM. I WISH I WOULD HAVE KNOWN ABOUT THIS SO I COULD HAVE HAD IT REPLACED AND NOT PUT IN DANGER. *TR

Oct 28, 2010

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.

Mar 3, 2010

NISSAN IS RECALLING CERTAIN MODEL YEAR 2006 AND MODEL YEAR 2008 FRONTIER, XTERRA AND PATHFINDER VEHICLES. THE MOLDED FUEL TANK SHELLS CAN DEFORM, CAUSING THE FUEL SENDER FLOAT ARM TO CONTACT AN EMBOSSMENT MOLDED INTO THE TANK SHELL CAUSING THE INSTRUMENT PANEL FUEL GAUGE TO SHOW THAT THE VEHICLE HAS APPROXIMATELY ONE QUARTER TANK WHEN THE FUEL TANK IS EMPTY.

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.

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.

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.
