IF THE AIR FILTER MATERIAL IGNITES, A FIRE MAY OCCUR.
Nissan is recalling 2007 Altima models because 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, which may cause a fire. Dealers will replace the air filter with a new one that has improved anti-flammability material characteristics.
