Recall History (4 recalls)
VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM:WINDSHIELD:ELECTRICAL HEATING ELEMENT
GENERAL MOTORS IS RECALLING CERTAIN MODEL YEAR 2011 BUICK LACROSSE AND CADILLAC SRX VEHICLES FOR FAILING TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 103, "WINDSHIELD DEFROSTING AND DEFOGGING SYSTEMS". ON THESE VEHICLES, THE SOFTWARE IN THE ELECTRONIC CLIMATE CONTROL (ECC) MODULE MAY DISABLE THE ABILITY TO ADJUST THE HEATING, VENTILATION, AND AIR CONDITIONING (HVAC) SYSTEM SETTINGS. IF THIS HAPPENS, THE DRIVER WILL NOT BE ABLE TO CONTROL THE HEATING, COOLING, AND VENTILATION FOR THE VEHICLE.
SEATS:FRONT ASSEMBLY:POWER ADJUST
General Motors LLC (GM) is recalling certain model year 2011-2012 Buick LaCrosse, Regal and Chevrolet Camaro, as well as certain 2010-2012 Cadillac SRX, Chevrolet Equinox and GMC Terrain vehicles, equipped with power height adjustable driver and passenger seats. In the affected vehicles, the bolt that secures the driver's and passenger's power front seat height adjuster may fall out causing the seat to drop suddenly to the lowest vertical position.
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.
