Electrical system:ignitionOct 9, 2015 · NHTSA campaign 15V640000 · 3,073 vehicles

Fix: 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.
