INTRODUCTION
Nissan is conducting a Voluntary Service Campaign on Model Year 2007-2012 Nissan Altima
(L32) Sedan and Coupe vehicles to inspect the brake system in vehicles with an illuminated
brake warning lamp. Nissan dealers will inspect the brake system and confirm that no brake fluid
leak is present. If no leak is present, the reservoir will be topped off. If a leak in the brake master
cylinder is identified, the brake master cylinder will be replaced.
The affected vehicles are equipped with a brake warning lamp that will illuminate to alert the
driver when fluid in the brake fluid reservoir is low. Fluid in the reservoir may become low due to
normal brake pad wear and not because of any brake system malfunction. While in most
instances an illuminated brake warning lamp is due to normal brake pad wear, a small
percentage of vehicles affected by this campaign may have a slow brake fluid leak at the brake
master cylinder.
IDENTIFICATION NUMBER
Nissan has assigned identification number PC125 to this campaign. This number must appear
on all communications and documentation of any nature dealing with this campaign.
DEALER RESPONSIBILITY
This action is only required if the brake warning lamp is currently illuminated, or the customer
states it was recently illuminated while driving. In addition, this campaign is intended to promote
customer satisfaction. This inspection may also be performed based on customer request,
regardless of the warning lamp illumination.
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.

OWNER’S LETTER
Dear Nissan Altima Owner:
Nissan is committed to providing the highest levels of product quality and customer satisfaction.
With that in mind, we want to bring to your attention important information regarding a service
campaign for the brake system on your Nissan Altima vehicle.
REASON FOR SERVICE CAMPAIGN
As your brake pads wear over time, the brake fluid level in the master cylinder reservoir will drop
and may cause the brake warning lamp to illuminate. Although this is a normal condition, there
has been concern that the brake warning lamp illumination may be caused by a slow fluid leak
over time. Nissan wants to address this concern to ensure your continued satisfaction and
confidence in your vehicle and confirm that no other brake system issues exist.
WHAT NISSAN WILL DO
Nissan is conducting a voluntary service campaign to check pad wear and for fluid leaks from
the master cylinder. As part of this service, the brake fluid will also be filled to its maximum
level. This inspection and fluid top off will be performed free of charge. Only a small
percentage of vehicles eligible for an inspection may have a low brake fluid level caused by a
slow leak. If a leak is detected in the master cylinder, the master cylinder will be replaced with a
new one free of charge for parts and labor. The brake pad inspection will be performed to
determine the remaining pad life in your brake pads, however, brake pads are a normal wear
item and replacement is not covered.
WHAT YOU SHOULD DO
You will only need to bring your vehicle to a Nissan dealer for an inspection if the brake warning
lamp in your Altima is illuminated (with engine running and parking brake OFF). Please contact
your Nissan dealer at your earliest convenience to arrange an appointment. This inspection
service should take about an hour or less to complete, but your Nissan dealer may require your
vehicle for a longer time based upon their service department schedule. To minimize your
inconvenience, it is important that you have an appointment before bringing your vehicle to the
Nissan dealer for service. Note that the brake pad inspection, fluid top off and master cylinder
replacement (if necessary) are the only services that qualify for free repair under this campaign.
Please bring this notice with you to your service appointment. Instructions have been sent to
your Nissan dealer.
If you have previously paid to have a master cylinder replaced out of warranty and seek
reimbursement, we ask that you visit www.NissanAssist.com, download the Reimbursement
Claim Form and follow the instructions on the site. If you have additional questions or concerns,
please contact your Nissan dealer or our Consumer Affairs office at (800)-867-7669. Only the
master cylinder is reimbursable under this campaign.
At Nissan we and our dealers work daily to deliver an outstanding ownership experience that will
earn your confidence and trust. Thank you for providing us an opportunity to ensure your ongoing satisfaction with your Nissan Altima.
