This recall affects certain vehicles equipped Occupant Classification System (OCS) control units manufactured by Continental Automotive Systems. A varistor in the OCS control unit may have been manufactured out of specification. Under certain conditions, this could interupt the signal between the OCS and the air bag control unit (ACU), causing the passenger air bag to be suppressed in an accident. If the air bag does not deploy when needed in a crash, the risk of injury is increased. Dealers will test the signal between the OCS and ACU with a special tool to verify proper function. The seat cushion containing the OCS hardware will be replaced as necessary. The recall began November 4, 2008.
2007 Nissan Altima Recalls
Nissan is recalling 2007-2008 Altimas because vehicles that have had the body control module (BCM) replaced during service at a dealership might have experienced inadvertent deactivation of the tire pressure monitoring system (TPMS) due to a software issue. If the TPMS is turned off, it would not alert the driver to a decrease in tire pressure, which could result in a crash. Dealers will check the TPMS function and reactivate it if necessary.
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.
