IN APRIL 2019 I WAS DRIVING MY 2006 NISSAN FRONTIER TRUCK 4X4 V6 . SUDDENLY I NOTICE A LACK OF POWER AND THEN IT DID NOT MOVE ANY WHERE. I CALL A TOW TRUCK SERVICES TO TAKE IT TO THE MECHANICS. THE WAS THE TRANSMISSION CONTROL MODULE FAILURE , DO TO THE RADIATOR COIL LEAKING. WE PUT A NEW RADIATOR AND BOUGHT A TRANSMISSION CONTROL MODULE THAT COST $964.00 DOLLARS. TH3 MECHANIC INSTALLED IT AND RECOMMENDED TO TAKE IT TO NISSAN FOR PROGRAMMING. AFTER 3 TIMES TRYING NISSAN SAD THAT THE CONTROL MODULE WAS DEFECTIVE. THIS ISSUE HAS COST ME ALMOST $2,500.00 IN TOWING AND LABOR BACK AND FORWARD AND STILL MY TRANSMISSION IS NOT WORKING. I AM NOW IN THE PROCESS OF BUYING A TRANSMISSION. THIS IS NOT FAIR HOW A COMPANY THAT KNOWS THAT PRODUCT IS DEFECTIVE WAIT UNTIL THE WARRANTY IS OVER AND DON'T FIX THE PROBLEM PRIOR. THEY ARE KNOW FOR THEIR CTV PROBLEMS WITH TRANSMISSION AND WITH THE RADIATOR COIL BEING DEFECTIVE. THIS COMPANIES OPERATING IN OUR COUNTRY ARE ABUSING THE CONSUMERS WITH NO BODY DOING JUSTICE. I HOPE THIS HOPE SOMEONE OR AT LEAST BRING AWARENESS TO OUR GOVERNMENT AGENCIES THAT PROTECT CONSUMERS. THANKS

VEHICLE WILL NOT CHANGE GEARS AND IS SLUGGISH. THE DISPLAY ON THE SPEEDOMETER DOES NOT SHOW THE POSITION OF THE TRANSMISSION. I HAVE SPENT OVER 600 DOLLARS TO FIND OUT THAT THE TRANSMISSION CONTROL MODULE IS BAD AND THAT THERE WAS A RECALL TO FIX COOLENT LEAKING INTO THE TRANSMISSION FLUID. MY VEHICLE IS STILL BROKEN BECAUSE OF THE PART COST 1100 USD AND THE REPAIR. TOTAL BILL IS 1600 USD. THIS WAS A KNOWN PROBLEM AND SHOULD BE FIXED WITHOUT ME PAYING A DIME. MY VEHICLE WAS IN MOTION. NOW IT WON'T EVEN GET UP TO SPEED THE TRANSMISSION SOUNDS AS IF IT IS STUCK IN A GEAR. VERY ERRATIC. MY CRUISE CONTROL ALSO JUST BLINKS AND WHEN THE MECHANIC TESTED THE CODES IT GAVE A NETWORK FAILURE CODE

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.

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.
