Subaru of America, Inc. has determined that a defect, which relates to motor vehicle safety, exists on certain 2005-2009 model year Subaru Legacy/Outback vehicles currently or formerly registered in at least one of the ?salt-belt? states listed below. These vehicles may have been manufactured with brake lines that could, over time, corrode in the area of the fourway joint connector if exposed to salt. Excessive corrosion could eventually cause perforation of a brake line(s) resulting in a brake fluid leak.
