About 575,000 Ford Windstar minivans from the 1998 to 2003 model years were recalled in August over concerns that the rear axles could corrode and potentially break.
The recalled vehicles were sold or registered in regions where heavy use of road salt can cause more corrosion. That includes Canada, New England, the Mid-Atlantic states and the Great Lakes region.
The National Highway Traffic Safety Administration said only about 75,000 of the minivans had been fixed by the recall, leaving a large number of vehicles still to be repaired.
Typically, 70 percent of recalled vehicles get fixed in 18 months.
