The 2024 Porsche Cayenne S has 3 recalls, the most serious affecting V8-equipped models where a loose connection on the high-pressure fuel pump can allow fuel to leak and create a fire risk.
The remaining two recalls both involve lighting. A software issue in the lighting control module can prevent the rear hazard warning lights and parking lights from turning on if they are activated within about 10 seconds of the vehicle shutting down, leaving the car invisible to other drivers approaching from behind. A separate software problem can cause the front turn signals to display the wrong color when the vehicle is parked with hazard lights active, which can confuse other road users about the car's status or intended movement.
