Long-time enemies of a vehicle’s current condition — corrosion and rust — created a recall of more than 660,000 units by Subaru of America.

The National Highway Traffic Safety Administration said Subaru is recalling four different models because of the possible excessive corrosion near the brake lines. The models included in the campaign are:

—2005-2009 Outback and Legacy
—2008-2011 Impreza
—2008-2014 Impreza WRX/STI
—2009-2013 Forester

NHTSA and the automaker believe there are 660,238 vehicles included for recall that currently are or formerly were registered in Connecticut, Delaware, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, Wisconsin and the District of Columbia.

“Salt water could splash on the brake lines through a gap in the fuel tank protector, resulting in excessive corrosion of the brake lines,” NHTSA said.

“Brake line corrosion may result in brake fluid leakage. Fluid leakage may result in longer distances being required to slow or stop the vehicle, increasing the risk of a crash,” the agency continued.

Subaru told NHTSA that it will notify owners, and franchised dealers will test the brake system by depressing the brake pedal and inspecting for brake fluid leaks.

If no brake fluid seepage is observed, officials said the affected areas will be rustproofed with anti-corrosion wax. If brake fluid seepage is observed, officials indicated the brake lines will be replaced followed by rustproofing with anti-corrosion wax.

NHTSA noted these services will be performed free of charge, and the automaker has not yet provided a notification schedule.

In the meantime, owners can contact Subaru at 1-800-782-2783 and mention recall campaign No. WQK-47.
