AT ABOUT 37,000 MILES, THE FUEL GAUGE ON MY 2006 NISSAN FRONTIER STARTED READING "EMPTY" NO MATTER HOW MUCH FUEL WAS IN THE TANK, AND THE "CHECK ENGINE" LIGHT CAME ON CONTINUOUSLY. THE FUEL SENSOR WAS REPLACED WITH A "REVISED" UNIT AND NOW AT 46,000 MILES, IT IS READING "EMPTY" ALL THE TIME, EVEN WHEN THE TANK IS FULL. *TR

NISSAN FRONTIER 2006 ALL HAVE A COMMON DEFECTIVE PART, THE FUEL LEVEL SENSOR. I HAVE THIS TRUCK AND AT APPROXIMATELY 43,000 MILES, THE SENSOR WENT OUT GIVING ME THE "SERVICE ENGINE SOON", CODE NUMBER P0463. THE NISSAN DEALER SAID IT WOULD $350 TO REPLACE, AT MY EXPENSE. AFTER FURTHER RESEARCH IN INTERNET FORUMS, THIS IS A COMMON DEFECT WITH ALL 2006 FRONTIERS WITH THE SENSOR GOING OUT AT APPROX 42,000-43,000 MILES. THE FUEL GAUGE NO LONGER FUNCTIONS, LEAVING THE OWNER NOT KNOWING HOW FULL THE FUEL TANK IS. THERE ARE POST ON VARIOUS FORUMS OF DRIVERS BEING STRANDED WITH AN EMPTY TANK DUE TO THIS DEFECTIVE PART. NISSAN HAS RECALLED SOME OF THE VEHICLES FOR THIS DEFECT BUT WHEN I ADVISED NISSAN CUSTOMER SERVICE THAT MY TRUCK HAD THE SAME DEFECT, I WAS TOLD THAT MY VIN WAS NOT PART OF THE RECALL. IT IS CLEAR THAT THE RECALL NEEDS TO BE BROADENED TO ALL VEHICLES PRODUCED IN THAT YEAR. *TR

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.

2DP26003 · 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.
