Nissan has determined that on some 2007 – 2008 Altima Sedans and 2008 Altima Coupes equipped with the 2.5 liter four cylinder engines, a rattle noise may occur around the exhaust manifold heat shield during start up or at low engine speeds (approximately 1600 RPM). The symptom does not affect the operation of the engine or the vehicle. To address this issue, Nissan is conducting a Voluntary Service Campaign to install an exhaust stay bracket, and if necessary, also replace the exhaust manifold heat shield.

Nissan has determined that some 2007 and 2008 model Altima vehicles are equipped with an improperly functioning on-board emission-related diagnostic system that violates California standards and regulations. This condition may result in failure of the on-board diagnostic system to warn a driver that the catalytic converter is malfunctioning. To correct

this condition, Nissan is conducting a Voluntary Emissions Recall Campaign to reprogram the Engine Control Module (engine computer). If this repair is not completed, affected vehicles may fail an emission inspection or I/M smog check test.

Nissan has determined that a defect which relates to motor vehicle safety exists in some 2007 and 2008 model year Nissan Altima vehicles. The vehicles affected by this campaign had the Body Control Module (BCM) replaced during service at a Nissan dealership after October 1, 2007 and before November 30, 2007. During that service, the Tire Pressure Monitoring System (TPMS) may have been inadvertently deactivated due to an issue with

the dealer service software. If the TPMS is turned off, it would not alert the driver to a decrease in the tire pressure as designed. Driving on under-inflated tires is unsafe and could result in a crash. To correct this potential condition Nissan is conducting a Voluntary

Nissan has determined that some 2007 Altima Sedan and 2008 Altima Coupe vehicles equipped with the 2.5 liter four cylinder engine may benefit from the installation of an air deflector to the front of the engine air intake system opening. The purpose of the air deflector is to reduce the potential of debris such as leaves and paper entering the air intake system and being deposited on the air filter, which may reduce engine performance. This enhancement has been added in production and Nissan would like to offer the Installation of the air deflector to customers who purchased a vehicle manufactured before this change was made.

Nissan is conducting a Voluntary Service Campaign to install this new air deflector on affected vehicles to the engine air intake system free of charge for parts or labor. If the vehicle is already equipped with the new air deflector then no further action is required.
