The 2018 Porsche Panamera 4 Executive has 3 recalls, the most serious involving moisture entering the climate control system's external coolant pump, which can cause an electrical short circuit and a vehicle fire.
The brake system recall involves a faulty wear indicator that fails to alert the driver when brake pads have worn down to a dangerous level. Without that warning, a driver may not know the pads are depleted until braking performance has already deteriorated, raising the risk of a crash. There is also an electrical concern where a fault can impair the vehicle's driveability, meaning the car may respond unpredictably or lose power in a way that reduces the driver's control on the road.
