The 2018 Porsche Panamera 4S has 4 recalls, the most serious involving moisture that can enter the climate control system's external coolant pump, cause an electrical short, and start a vehicle fire.
On the chassis side, a rear suspension defect can produce sudden, unexpected changes in handling that raise the risk of a crash. The electrical system has a separate concern where a fault can impair the vehicle's driveability, also increasing crash risk. There is also a brake-related recall: the wear indicator for the brake pads can fail to alert the driver when pads are worn down, meaning the driver may attempt to brake and find reduced stopping ability without any warning.
