NHTSA opens probe into about 75,000 Nissan Frontier trucks over fuel leak concerns

March 31 (Reuters) - The National Highway Traffic Safety Administration on Tuesday launched a probe into about 75,300 model-year 2006 Nissan Frontier pickup trucks due to concerns about potential fuel leaks.

The agency said the vehicles may pose an imminent fire hazard due to a strong, persistent odor of raw gasoline and sudden engine stalling during startup and operation, citing a petitioner.

Nissan previously recalled certain the 2006 Frontier pickup trucks in 2007 to replace fuel filler tube assemblies that could crack and cause fuel leaks.

The petitioner alleged the problems resemble defects cited in those earlier recalls and may still be present in the 2006 Frontier fleet despite the prior actions, the report said.
