DETROIT (AP) — Hyundai is recalling 239,000 Sonata and Azera sedans in cold-weather states because road salt can corrode the rear suspension. The recall affects 215,000 Sonata midsize sedans from the 2006 to 2010 model years and 24,000 Azera full-size sedans from 2006 to 2011.

Hyundai says salt can corrode the rear suspension crossmember, which is part of the vehicle’s frame. In advanced cases, the crossmember could detach from the control arms that lead to the wheels, which could affect wheel alignment and increase the risk of a crash. Hyundai will inform owners next month. Dealers will inspect the cars and repair or replace the defective parts.

The recall affects vehicles registered in Connecticut, Delaware, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, Wisconsin, Delaware and Washington, D.C.
