POWER TRAIN:AUTOMATIC TRANSMISSION
General Motors (GM) is recalling certain model year 2013 Buick LaCrosse vehicles, manufactured between April 25, 2012, through March 6, 2013, and model year 2013 Cadillac SRX vehicles, manufactured between May 29, 2012, through February 18, 2013 for failing to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 102, "Transmission Shift Lever Sequence, Starter Interlock, and Transmission Braking Effect."

ELECTRICAL SYSTEM
General Motors (GM) is recalling certain model year 2012 and 2013 Buick LaCrosse and Regal, and model year 2013 Chevrolet Malibu Eco vehicles equipped with eAssist.

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.
