Nissan is conducting a Voluntary Service Campaign on Model Year 2007-2012 Nissan Altima (L32) Sedan and Coupe vehicles to inspect the brake systems 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. See this bulletin for further detail. Campaign ID# PC125
