On certain vehicles, if a sufficiently hot object enters the air filter housing through the engine fresh air intake system and contacts the engine air filter, the flammability characteristics of the air filter material are such that the filter may ignite.
Dealers will replace the air filter with a new one that has improved anti-flammability material characteristics. The recall began on July 3, 2007, and will continue through October 1, 2007. Owners may contact Nissan at 1-800-647-7261.
