- Owners report a loose ground cable causing warning lights, followed months later by an underhood fire while driving at low speed.

Electrical system:ignition
General Motors LLC (GM) is recalling certain model year 2014-2015 Chevrolet Silverado and GMC Sierra trucks manufactured January 24, 2014, to February 26, 2014, 2015 Chevrolet Suburban vehicles manufactured February 12, 2014 and Chevrolet Tahoe vehicles manufactured February 6, 2014, to February 13, 2014. 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.
Remedy: GM will notify owners, and dealers will replace the ignition lock housing, free of charge. The recall began on November 20, 2015. Owners may contact Chevrolet customer service at 1-800-222-1020 or GMC customer service at 1-800-462-8782. GM's number for this recall is 15573.
