Nissan has determined that a defect which relates to motor vehicle safety exists in some 2002 and 2005-2006 model year Nissan Altima and Sentra vehicles equipped with the 2.5 liter engine. On some of these vehicles there is a possibility that the engine might stop running while being driven due to the program in the Electronic Control Module (engine computer). If the engine stops running while driving, this could result in a crash without warning. To prevent this potential condition, Nissan is conducting a Voluntary Safety Recall Campaign to reprogram the Electronic Control Module.

On some model year 2002-2005 Nissan Altima and 2004-2005 Nissan Maxima vehicles, there is a possibility that corrosion of the rear sub-frame may occur. Corrosion is most likely in cold climates where heavy salting of roads is common practice in freezing conditions. A mixture of road salt and water can promote corrosion in the rear sub-frame bushings of some vehicles. In severe cases, cracking of the rear sub-frame may occur, which may result in a knocking noise coming from the rear of the vehicle. The performance or handling characteristics of the vehicle are not affected and it is safe to drive the vehicle.

On some model year 2005 Maxima and Altima vehicles, the Air Bag Warning Light may flash even though the air bag systems it monitors are operating properly. To prevent this condition, Nissan has initiated a Voluntary Service Campaign to replace the Passenger Air Bag Status Light Control Circuit which is causing this to happen.

Nissan has determined that some 2005 Altimas may have a tire vibration or ride harshness condition. To correct this condition, Nissan is conducting a service campaign to replace the tires on these vehicles. For all vehicles in this population (you must confirm using Service Comm) the tires (except spare) must be replaced.
