OpenDefect Petition

This investigation is open. That is not a finding that a defect exists.

NHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.

What NHTSA is examining

The agency's own description of the inquiry, quoted as published

Fuel smell and loss of motive power

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.

An investigation is a separate record from a recall and from a manufacturer communication. A manufacturer campaign to repair a safety defect or a failure to meet a federal safety standard.
