SUSPENSION:REAR

General Motors, LLC (GM) is recalling certain 2012-2013 Buick Regal, 2013 Chevrolet Malibu, and 2010-2013 Buick Lacrosse vehicles sold or ever registered in Connecticut, Delaware, the District of Columbia, Illinois, Indiana, Iowa, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, Virginia, West Virginia, or Wisconsin. These vehicles may have rear toe links that received excessive electrocoating (e-coat) corrosion protection, which could cause the e-coat to become brittle and break away when contacted by road debris. Over time, the e-coat may chip away, exposing the metal toe link and making it more susceptible to corrosion. Corrosion may eventually cause the toe link to thin and ultimately to fracture.
