Every line below is in NHTSA’s own words, with its source beside it.
What’s wrong with it?
In the event of a crash, improper air bag deployment can increase the risk of injury.
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.
