What can fail
The front passenger seat's occupant detection system may incorrectly identify a child car seat as an adult if installed after an adult has sat there, without a complete key-on/key-off cycle with the seat empty first.
What the fix does
Dealers will reprogram the occupant detection system's computer to remove the feature that causes child seats to be misidentified as adults.
