NHTSA campaign 18V400000
Hazard
General Motors LLC (GM) is recalling certain 2016-2018 Chevrolet Malibu vehicles. During servicing, a Passenger Presence System (PPS) may have been installed that was not correctly calibrated to the vehicle's seat type. As a result, the PPS may not properly identify an adult passenger from a child passenger in the front passenger seat, potentially causing the air bag to not deploy when it should, or causing the air bag to deploy when it shouldn't.
Consequence
In the event of a crash, improper air bag deployment can increase the risk of injury.
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.
