Another big recall to report. This time it's Nissan and its bread-and-butter Altima sedan. Apparently, cars with the 2.5-liter four-cylinder have an air filter that can cause some serious problems. It seems that if something hot is sucked into the filter, like ashes from a cigarette, it can catch on fire. Four incidents have already been reported to Nissan. Notices started going out to some of the 140,000 2007 Altima owners last week. Besides replacing the air filter with a presumably less flammable one, Nissan will also add an air deflector to help prevent a potential accumulation of debris in the filter.

In all, 140,582 Altimas have been sold so far this year, making it Nissan's best-selling vehicle, and the ninth-best seller overall in the States. The recall affects Smyrna, Tennessee cars made between Sept. 25 and May 11, as well as those built from Oct. 30 through May 11 at its Canton, Mississippi, factory.
