2013 ALTIMA SEDAN; NOISE FROM THE
HYDRAULIC ELECTRIC POWER STEERING (H-EPS)
This bulletin has been amended. On pages 15 and 16, “For vehicles built after the applied VIN and
date” was changed to “For vehicles built before the applied VIN and date”.
Please discard previous versions of this bulletin.

APPLIED VEHICLE: 2013 Altima Sedan (L33)
APPLIED VINs and
DATES: See the Repair Flow Chart on page 2.
IF YOU CONFIRM:
The customer is experiencing a noise coming from the passenger side engine compartment
and
The source of the noise is confirmed to be the Hydraulic Electric Power Steering (H-EPS)
and
The noise is louder than the normal operational noise of the H-EPS.
NOTES:
•

The 2013 Nissan Altima sedan 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. You may hear some normal
operational noise 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 the H-EPS noise is louder than normal.

ACTION:
Refer to the Repair Flow Chart on page 2.

IMPORTANT: The purpose of ACTION (above) is to give you a quick idea of the work you
will be performing. You MUST closely follow the entire SERVICE PROCEDURE as it
contains information that is essential to successfully completing this repair.
Nissan Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are
properly trained individuals who have the equipment, tools, safety instruction, and know-how to do a job
properly and safely. NOTE: If you believe that a described condition may apply to a particular vehicle, DO
NOT assume that it does. See your Nissan dealer to determine if this applies to your vehicle.
