2006 NISSAN FRONTIER TRANSMISSION FAILING DUE TO ENGINE COOLANT AND TRANSMISSION FLUID MIXING. TRUCK STARTED JERKING AT TIMES JUST CRUISING USUALLY BETWEEN 40 AND 50 MPH THEN WORSE. COOLANT RESERVOIR AND RADIATOR WAS NOTICED IN COMPONENTS. TOOK IT TO DEALERSHIP AND GAVE ME A PRICE OF 5300 TO REPLACE RADIATOR AND TRANSMISSION AND FLUSH ALL SYSTEMS. I HAD BEEN READING REVIEWS ON THESE MODELS AND WAS HOPING THIS WASN'T THE ISSUE ON MINE. AS SOON AS I NOTICED THE FLUID CONTAMINATION I WAS SICK. HAD NO IDEA OF THIS PROBLEM. ALOT OF REVIEWS SAY STEER CLEAR OF THESE VEHICLES. THIS FRONTIER IS MY 3RD OWNED NISSAN VEHICLE. NEVER AGAIN!!!!!!!!

RECENTLY MY 2006 NISSAN FRONTIER TRANSMISSION STARTED TO MAKE A GRINDING NOISE AT SPEEDS WHEN SHIFTING TO A LOWER GEAR. I CHECKED THE COMPUTER ABOUT POSSIBLE PROBLEMS; THAT IS WHEN I FOUND OUT ABOUT THE TRANSMISSION LINES FAILING INSIDE OF THE RADIATOR. THE WATER WAS LEAKING INTO MY TRANSMISSION. NISSAN AND THE DEALERSHIP THAT I WAS GETTING MY TRUCK SERVICED KNEW OF THE PROBLEM FOR MANY YEARS. WHEN I ASKED THE SERVICE ADVISER ABOUT THE PROBLEM, HE TOLD ME MY FRONTIER HAD 7,000 OVER 100,000 MILES AND THAT WAS THE CUTOFF FOR NISSAN TO HELP. WHAT MADE ME MAD WAS THAT I HAD MY 90,000 MILE SERVICE DONE AT THE DEALERSHIP ON 01/28/2014 , PAID $523.38 AND NOTHING WAS TOLD TO ME SO I COULD TAKE ACTION TO SAVE MY TRANSMISSION!!! I SHOULD HAD BEEN TOLD OF THE DEFECTIVE TRANSMISSION LINES BEFORE IT RUINED MY TRANS. NOW I AM OUT $3,228.78 FOR A REBUILT TRANSMISSION. THEY KNEW I HAD THE FRONTIER, WHY DIDN'T THEY TELL ME OF THE DEFECTIVE TRANSMISSION LINES... I DON'T UNDERSTAND...

I WAS TOLD THIS WAS AN INHERENT PROBLEM WITH THIS MODEL AND OTHERS MADE BY NISSAN AND NISSAN HAS SINCE CHANGED HOW THEY BUILT THEIR CARS. I HAVE BEEN TOLD I CAN ONLY DRIVE IT SEMI SAFELY AROUND TOWN, NO GOING OVER THE MOUNTAINS AND ABSOLUTELY NO TOWING WITH IT WHICH IS WHY I BOUGHT THIS TRUCK, TO TOW MY TRAILER. I AM A DISABLED SENIOR ON A FIXED INCOME AND HAVE NO EXTRA MONEY TO FIX MUCH LESS BUY A NEW VEHICLE. I OWE AROUND $27000. ON IT AND WENT AS FAR AS TO BUY AN EXTENDED WARRANTY WHICH WILL NOT COVER THESE ISSUES. I DO NOT UNDERSTAND WHY IF THIS IS THAT BIG OF A PROBLEM IT HAS NOT BEEN RECALLED. THIS VEHICLE HAS 7 OTHER RECALLS PER YOU WEBSITE SO THIS BECOMES A REAL PROBLEM.

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.
