What's wrong?
The hazard warning lights on a 2020 Porsche 911 Carrera are the flashing exterior lamps the driver turns on with the hazard switch. Their normal job is to make the vehicle easier to recognize when it is stopped, disabled, or creating a road hazard. The system depends on the switch command reaching the lighting software and then activating the lamps outside the car.
On affected Porsche vehicles, a software error prevents the hazard warning signal from activating as designed under specific conditions. The driver presses the switch, but the exterior hazard lamps do not flash. That means the vehicle does not provide the warning signal required by FMVSS 108 when the driver asks for it.
The driver has a warning sign after pressing the switch. Porsche says the vehicle gives visual and audible confirmation that the hazard warning lamps did not activate, so the driver should notice that the hazard signal failed to turn on.

What's the safety risk?
If the hazard warning lights fail to activate, other drivers receive less warning during a breakdown or roadside hazard, increasing the risk of a crash in that situation. The vehicle gives visual and audible confirmation when the hazard lamps are not activated after the switch is pressed. Repair is free at any franchised Porsche dealer.
