Recalls (4)
SUSPENSION:REAR · Campaign 21V00F000 · Dec 22, 2021
Defect: General Motors, LLC (GM) is recalling certain 2010-2013 Buick Lacrosse, 2012-2013 Buick Regal, and 2013 Chevrolet Malibu 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 an improper amount of 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 fracture.
Consequence: A rear toe link fracture may reduce the driver's ability to control the vehicle, increasing the risk of a crash.
Remedy: Dealers will replace the rear suspension toe links and adjuster fasteners, free of charge. Owner notification letters were mailed January 27, 2022. Owners may contact Buick customer service at 1-800-521-7300 or Chevrolet customer service at 1-800-222-1020. GM's number for this recall is N212346640.
