Defect
On certain vehicles, the front passenger seat occupant sensor mat could stop working over time. This could cause the airbag system to turn off the passenger-front airbag even when a passenger is seated. Note: The airbag warning light or passenger airbag OFF light will turn on if the sensor mat stops working.
Safety Risk
An airbag that is turned off could increase the risk of injury to a passenger in a crash.
Remedy
Porsche will notify owners by mail and instruct you to take your vehicle to a dealer to replace the front passenger seat cushion and occupant sensor mat.
