DRIVING ON BUSY ROAD AT APPROXIMATELY 40MPH WHEN MY TRUCK STARTED TO SHAKE, I SLOWED MY TRUCK TO APPROXIMATELY 37 MPH, WHEN IT SOUNDED LIKE MY TRUCK EXPLODED. I COULD NOT STOP AND COULD BARELY TURN THE STEERING WHEEL ENOUGH TO GET OUT OF TRAFFIC JUST TO SMASH INTO THE CURB WHERE I FINALLY CAME TO A STOP. THE DRIVE SHAFT CAME APART, GRABBING THE EMERGENCY BRAKE CABLE, WINDING IT AROUND ONE PART OF THE DRIVE SHAFT, LEAVING ME STRANDED WITH MINORS ON THE SIDE OF THE ROAD WAITING FOR A WRECKER TO TOW MY TRUCK. HAD I HAVE BEEN ON THE INTERSTATE, DOING THE SPEED LIMIT (70MPH) WHEN THIS HAPPENED, MY CHILDREN AND I WOULD HAVE FLIPPED NOSE OVER TAIL, POSSIBLY BE STRUCK BY TRAFFIC AND SERIOUSLY INJURED OR KILLED. *TR

CONTACTED A MECHANIC BECAUSE MY TRUCK WOULD SHAKE AT SPEEDS AT OR ABOVE 50 MPH. IT WAS ALSO STARTING TO SHIFT VERY HARD. THE MECHANIC CHECKED IT OUT AND TOLD ME THAT THERE WAS A VERY COMMON PROBLEM WITH THE RADIATOR FAILING AND CAUSING COOLANT AND WATER TO GET INTO THE TRANSMISSION... WHICH ISNT GOOD AT ALL FOR IT. RADIATOR AND TRANSMISSION ARE SHOT AND NEED TO BE REPLACED. HE TELLS ME THAT NISSAN HAS HAD THIS PROBLEM FOR SOME TIME NOW WHICH WAS NEWS TO ME. YOU WOULD THINK NISSAN WOULD LET OWNERS KNOW ABOUT A PROBLEM SO SEVERE AND COMMON. NOW I'M ON THE HOOK FOR $4000 THANKS TO NISSAN AND IT VERY UNPROFESSIONALISM. *TR

I BOUGHT MY 2006 NISSAN FRONTIER IN FOR REGULAR MAINTENANCE, DURING THE DEALER INSPECTION THEY NOTICED A NOISE COMING FROM THE ENGINE. THE NOISE IS A WHINING SOUND AND I THOUGHT NOTHING OF THE NOISE UNTIL THEY STATED THAT ITS THE TIMING CHAIN AND THAT IT NEEDS TO BE REPLACED. FROM THE RESEARCH I DID THE TIMING CHAIN IS SUPPOSED TO BE A NON-SERVICEABLE ITEM AND SHOULD LAST THE ENTIRE LIFE OF THE VEHICLE. UPON FURTHER INVESTIGATION I FOUND THAT THIS WAS A KNOWN DEFECT THAT NISSAN MOTOR CORP IS AWARE OF. NISSAN MOTOR CORP HAD ISSUED TSB'S FOR THIS ITEM AND THEY HAVE EVEN BEEN PART OF A CLASS ACTION LAWSUIT. WHY WERE NISSAN OWNERS NOT MADE AWARE OF THIS ISSUE? NOW I AM FACED WITH A $1,500 REPAIR DECISION. FROM WHAT I HAVE ALSO READ IF THIS CHAIN BREAKS IT CAN HAVE SERIOUS SAFETY ISSUES FOR THE DRIVER, WHY HAS NISSAN NOT SET UP A RECALL FOR THIS ISSUE. *TR

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

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

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.
