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.
Risk: If the driver's seat unexpectedly drops, the distraction and altered seat position may affect the drivers' control of the vehicle, increasing the risk of a crash.
Remedy: GM will notify owners, and dealers will replace the height adjuster shoulder bolts, free of charge. The manufacturer distributed interim letters to owners on September 11, 2014. The recall began on December 26, 2014. Owners may contact GM customer service at 1-800-521-7300 (Buick), 1-800-458-8006 (Cadillac), 1-800-222-1020 (Chevrolet), or 1-800-462-8782 (GMC).
