THE AUTOMATIC TRANSMISSION COOLING LINES WERE COMPROMISED IN THE RADIATOR. COOLANT CONTAMINATED THE AUTOMATIC TRANSMISSION FLUID AND RUINED THE TRANSMISSION SPECIFICALLY CAUSING THE RELAY IN THE TRANSMISSION THAT IS CONNECTED TO THE STARTER CIRCUIT TO MALFUNCTION. THERE WAS THEREFORE NO WARNING THAT ANYTHING WAS WRONG UNTIL THE TRUCK SIMPLY WOULD NOT START. THE QUOTE FROM THE DEALERSHIP IS $6,600. THIS IS PARTICULARLY FRUSTRATING BECAUSE 6 MONTHS AGO I PAID FOR A FULL INSPECTION OF THE VEHICLE AND THOUGH THIS IS A KNOWN ISSUE THAT IS PREVENTABLE, THERE WAS NO MENTION OF IT IN THE REPORT.

ACCORDING TO THE MECHANIC, THE TRANSMISSION COOLANT RESERVOIR (WHICH IS CONNECTED TO THE RADIATOR) COLLAPSED CAUSING WATER, ANTIFREEZE AND TRANSMISSION FLUID TO MIX. THESE FLUIDS THEN MADE THEIR WAY INTO THE RADIATOR, TRANSMISSION AND COOLANT RESERVOIR. THIS, IN TURN, CAUSED EXTENSIVE DAMAGE TO MY TRANSMISSION. MY TRANSMISSION THEN REQUIRED REPLACEMENT/REBUILD. THE FIRST POSSIBLE SIGN OF THE PROBLEM WAS ROUGH AUTOMATIC SHIFTING OF THE VEHICLE. I THEN NOTICED A LEAK OF TRANSMISSION FLUID FROM THE FRONT PASSENGER SIDE OF THE VEHICLE (WHICH WAS PARKED IN MY DRIVEWAY). THIS WAS FOLLOWED BY A LOSS OF POWER/DRIVABILITY.

I BOUGHT THE TRUCK AND LESS THAN A WEEK LATER I NOTICED A WEIRD RUMBLING NOISE AT AROUND 35-50 MPH AND 1-2 RPMS. ONE TIME WHILE I WAS BY MYSELF IN THE MOUNTAINS SCOUTING FOR AN ELK HUNTING TRIP, THE TRUCK WOULD NOT GO INTO REVERSE. THIS COULD HAVE BEEN VERY BAD AS I WAS ISOLATED OTHERWISE DEEP IN UTAH MOUNTAINS IN THE FALL. TOOK THE TRUCK IN AND FOUND IT WAS TRANSMISSION FAILURE JUST LIKE EVERYONE ELSE HAD WRITTEN ABOUT ON THE INTERNET. EXTENDED WARRANTY REPLACED TRANSMISSION FOR $100.00. 6 MONTHS LATER, I WAS STILL NERVOUS ABOUT THE ISSUE AND BEFORE A BIG TRIP I DID SOME MORE RESEARCH. PEOPLE WITH SIMILAR PROBLEMS WERE POINTING AT THE RADIATOR AND WARNED TO CHECK IT FOR TRANSMISSION OIL CONTAMINATION. CHECKED IT LAST NIGHT AND THE RADIATOR IS FULL OF TRANSMISSION OIL. TRUCK IS CURRENTLY IN THE SHOP.

10V517000 · Engine And Engine Cooling

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.

IF THIS OCCURS, THE CZS MAY INTERNALLY RUST RESULTING IN A SIGNAL INTERRUPTION. IF THIS HAPPENS, THE RED AIR BAG WARNING LIGHT WILL ILLUMINATE TO ALERT THE VEHICLE OPERATOR.

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.

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.
