2012 GMC Sierra recalls
Recall 14V-827: Electrical System
Problem: General Motors LLC (GM) is recalling certain model year 2011-2012 Cadillac Escalade, Escalade ESV, Escalade EXT, Chevrolet Avalanche, Silverado HD, Silverado LD, Suburban, Tahoe, GMC Sierra LD, Sierra HD, Yukon, and Yukon XL vehicles. In the affected vehicles, the ignition lock actuator may bind, making turning the key difficult or causing the ignition to get stuck in the "Start" position.
Risk: If stuck in the "Start" position, the ignition may suddenly snap back into the "Accessory" position, causing a loss of engine, steering, and braking power, increasing the risk of a vehicle crash. If the vehicle is in a crash, the air bags may not deploy, increasing the risk of occupant injury.
Fix: GM will notify owners, and dealers will inspect and replace the ignition lock housing, as necessary, free of charge. The recall began on February 12, 2015. Owners may contact GM customer service at 1-800-458-8006 (Cadillac), 1-800-222-1020 (Chevrolet), or 1-800-462-8782 (GMC).

Problem: General Motors LLC (GM) is recalling certain model year 2012-2013 Chevrolet Silverado HD and GMC Sierra HD vehicles, equipped with 6.6L diesel engines and dual fuel tanks. In the affected vehicles, the transfer pump which moves fuel from the rear tank to the front tank could malfunction and cause the fuel gauge to indicate an inaccurate reading.
Risk: If the fuel gauge indicates an inaccurate reading it may result in the vehicle unexpectedly stalling, increasing the risk of a crash.
Fix: General Motors will notify owners and dealers will inspect and replace the fuel transfer pump, as necessary, free of charge. The manufacturer has not yet provided a notification schedule.
