The 2024 Porsche Cayenne S has 3 recalls, the most serious involving fuel connections on the high-pressure fuel pumps that can loosen and leak, creating a fire risk. This recall only affects V8-equipped models.
The remaining two recalls both involve lighting. A software issue 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 parked car less visible to other drivers. A separate software issue can cause the front turn signals to display the wrong color when the hazard lights are active, which can create confusion for nearby drivers.
