Affected Component: ELECTRICAL SYSTEM

Summary
SERVICE INFORMATION As with other Nissan vehicles, the Altima is equipped with Hydraulic Electric Power Steering (H-EPS). This system uses an electric motor to drive a pump rather than relying on a conventional belt-driven pump. Some normal operational sound may be heard from the front of the vehicle generated by the H-EPS when the steering wheel is operated. Comparing the incident vehicle to a "known good vehicle" will help determine if there is louder than normal H-EPS related sound. If diagnosed as having louder than normal H-EPS sound, use this bulletin to assist in locating and repairing the cause. See this bulletin for further detail.
