Summary: General Motors LLC (GM) is recalling certain 2016-2018 Chevrolet Malibu vehicles.

Safety Consequence: In the event of a crash, improper air bag deployment can increase the risk of injury.
Manufacturer Remedy: GM will notify owners, and dealers will replace the front passenger PPS seat service kit, free of charge. The recall began August 7, 2018. Owners may contact Chevrolet customer service at 1-800-222-1020. GM's number for this recall is 18208.
