Nissan has determined that some 1999-2003 model year Nissan Frontier vehicles, equipped with the 6 cylinder engine and 2000-2003 model year Nissan Xterra vehicles, equipped with the 4 and 6 cylinder engine may have a defect which relates to motor vehicle safety. There is a possibility that the fuel pump terminal on the fuel-sending unit may develop a crack in its plastic molding which could cause the terminal strip to corrode under some environmental conditions. If corrosion occurs, the terminal strip could eventually break. This will cause the fuel pump to stop operating and will result in not being able to start the engine or cause the engine to stop running without warning during vehicle operation, which could result in a crash. To prevent this condition from occurring, Nissan is conducting a Voluntary Safety Recall Campaign to replace or repair the fuel-sending unit.

Nissan has identified that certain model year 2001-2002 Frontier and Xterra models and certain 2001 Altima models may experience unexpected or difficult operation of the windows. The primary cause is extended high temperature conditions affecting the window regulator system. These high temperature conditions generally occur in the states listed on

the next page of this bulletin. In these areas, Nissan has initiated a Voluntary Service Campaign to replace the affected window regulators with the improved design. In other areas where this incident in not expected to occur, Nissan is extending the warranty on the vehicles should a future repair be needed.

Nissan has identified the need to update Owner’s Manual information for the 2000 through 2003 Frontier and Xterra models related to the rear jacking points for vehicles equipped with 15” factory wheels. Vehicles equipped with 16” factory wheels are not affected.

Nissan is conducting a Service Campaign to update the affected pages in the Owner’s Manual.

Nissan has determined that on some 2001-2003 model year four wheel drive Nissan Frontier and Xterra vehicles, there is a possibility that water may enter the rear axle housing due to inadequate sealing of the ABS sensor in the axle housing. This may result in corrosion and eventual failure of the wheel bearing. If this occurs, the wheel assembly could separate from the vehicle and result in loss of control of the vehicle and a crash. To prevent this condition from occurring, Nissan is conducting a Voluntary Safety Recall Campaign to inspect the rear axle for water entry and replace any necessary parts. Also, the ABS sensor will be resealed to prevent water from entering.

Nissan has determined that on some 2002 model year Nissan Frontier and Xterra vehicles equipped with a supercharger, there is a possibility that the engine malfunction indicator lamp may come on and the engine speed may become severely limited. This condition may be due to the programming of the engine control module and may occur under certain conditions, such as full throttle in low gear when the engine is not fully warmed up and at cold ambient temperature. If this condition occurs unexpectedly, it could lead to a crash. To prevent this condition from occurring, Nissan is conducting a Voluntary Safety Recall Campaign to reprogram the engine control module.
