Electrical system:ignitionDec 30, 2014 · NHTSA campaign 14V827000 · 84,192 vehicles

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.

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.
