2006 NISSAN FRONTIER NISMO'S FUEL GAUGE IS ERRATIC. IT STARTED AT ABOUT 37,000 MILES, BUT I IGNORED IT BECAUSE I HAD ALLOWED THE WARNING LIGHT TO GO ON AND THOUGHT THAT AFTER A FEW FILL UPS IT WOULD REGISTER CORRECTLY, BUT IT DID NOT LEAVING ME STRANDED ON THE ROAD. THE DEALER, ALTHOUGH THEY ACKNOWLEDGE THIS IS A COMMON DEFECT IN THE VEHICLE, ASKED FOR OVER $400 TO REPAIR, WHICH I DO NOT HAVE. NOW I HAVE TO KEEP FILLING THE TANK AFTER EVERY 200 -250 MILES FEARING I MAY RUN OUT OF GAS AGAIN. THERE SHOULD BE A RECALL ON THIS AS IT CREATES A SAFETY HAZARD SUCH AS WHEN I RAN OUT OF FUEL ON THE TURNPIKE. *TR

AT 41,000MILES MY 2006 NISSAN FRONTIER V6 BEGAN HAVING A MALFUNCTIONING FUEL SENDING UNIT CAUSING IMPROPER READING OF THE FUEL GAUGE. UPON RESEARCHING THIS PROBLEM, I REALIZED THAT THIS IS A COMMON PROBLEM AFFECTING NISSANS WITH THE 4.0L V6 IN XTERRA'S, PATHFINDERS AND FRONTIERS. THIS USUALLY OCCURS BETWEEN 39K-49K MILES. NISSAN HAS NO RECALL FOR THIS AND I FEEL THIS IS A POTENTIAL HAZARD CONSIDERING THAT THE FUEL GAUGE IS MISREADING. NISSAN WANTS THEIR CUSTOMERS TO PAY $450 FOR A PART THAT IS DEFECTIVE ON THEIR PART.

THE FUEL SENDING UNIT HAS QUIT WORKING FOR THE SECOND TIME WHICH CAUSES THE FUEL GAUGE TO GIVE FALSE READINGS. NISSAN REPLACED THE UNIT WHEN IT QUIT AT 10000 MILES UNDER WARRANTY BUT, NOW THE VEHICLE IS OUT OF WARRANTY AND THE UNIT IS NOT WORKING AGAIN. AFTER TALKING WITH SEVERAL OWNERS OF THE SAME VEHICLE I FOUND OUT WE ARE ALL HAVING THE SAME PROBLEM, GOING THROUGH MULTIPLE UNITS. NISSAN DOES SEEM TO BE FIXING THE PROBLEM BUT, JUST COVING IT UP. AFTER TALKING WITH THE DEALERSHIP THEY DO NOT WANT TO TRY TO COVER IT, THEY WANT ME TO PAY $400 FOR PARTS AND LABOR WHICH I AM NOT GOING TO DO. BESIDES THE FACT THAT $100 FOR PARTS AND $300 FOR LABOR IS OUTRAGEOUS I AM NOT GOING TO REPLACE THIS PART JUST HAVE IT FAIL AGAIN. THIS PART SHOULD BE ON A RECALL BECAUSE IT IS CLEARLY DEFECTIVE AND NOT A PART THAT SHOULD HAVE TO BE REPLACED 2, 3, OR 4 TIMES OR EVEN AT 10000 MILES. NOW MY PROBLEM IS THE TRUCK SEEMS TO BE USING MORE GAS BECAUSE OF THIS. I HAVE BEEN GOING OFF OF THE MILEAGE BECAUSE I KNOW MY VEHICLE WILL DO A LITTLE OVER 400 MILES ON A TANK OF GAS BUT, IT LEFT ME ON THE SIDE OF THE HIGHWAY IN A BAD NEIGHBORHOOD AT 11:30 AT NIGHT WITH 352 MILES SHOWING. MY GIRLFRIEND ALSO HAS TO DRIVE THIS TRUCK AND I FEAR HER SAFETY WHEN SHE IS DRIVING THE VEHICLE. SHE COULD GET STUCK IN A BAD NEIGHBORHOOD OR IN DALLAS, TX TRAFFIC IT IS NOT EASY TO GET TO THE SIDE OF THE ROAD WHEN IT RUNS OUT OF GAS. ALSO, THIS PROBLEM SETS OFF THE CHECK ENGINE LIGHT AND THE VEHICLE INSPECTION IS OUT. THEY WILL NOT LET THE VEHICLE PASS WITH THIS ON. *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.

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.
