This notice is sent to you in accordance with the National Traffic and Motor
Vehicle Safety Act. Porsche has decided that a defect that relates to
motor vehicle safety exists in certain 2021 Model Year Porsche 911 Turbo,
911 Turbo S and 911 Carrera 4S vehicles.
You received this notice because our records, which are based primarily on
state registration and title data, indicate that you are the current owner of
a vehicle affected by this action.
What is the issue?

front passenger airbag may not deploy in the event of a crash, increasing
the risk of injury.
What should you do?
Please wait for our follow up letter to bring
your vehicle in for a remedy.
In the meantime, if the red air bag warning
lamp is illuminated in the instrument cluster
or the yellow “Passenger Airbag OFF“ status
lamp is illuminated in the overhead console
when the front passenger seat is occupied
by an adult, then do not use the front
passenger seat until the remedy has been
performed and please immediately contact

programmed with the PIWIS Tester. The vehicle voltage must be maintained between 13.5 volts and 14.5
volts during this programming. Failure to maintain this voltage could result in damaged control unit(s).

Seat occupancy detection system for passenger seat
Due to an incorrect parts list, the affected vehicles were installed with a passenger seat variant
that is not approved for the affected market.
As a result, it is possible that the electrical signal in the passenger seat is insufficient to correctly
recognize certain occupants in the passenger seat. Under certain circumstances, this can interrupt
triggering of the restraint systems on the passenger side. The airbag warning light or “Passenger Airbag
OFF” light is activated in order to alert the driver.
Action required: Replace the seat occupancy detection system according to the campaign scope assigned to the
respective vehicle.
Information
To find out which campaign scope is assigned to the respective vehicle for replacing the seat
occupancy detection system, see PIWIS Vehicle Information.
• Scope 1: 18-way sports seat without fire extinguisher
• Scope 2: 14-way comfort seat without fire extinguisher
• Scope 3: 18-way sports seat with fire extinguisher
• Scope 4: 14-way comfort seat with fire extinguisher
