The 2012 Porsche Panamera 4S has 4 recalls, with two tied for most serious: the transmission can fail to indicate the correct gear position, allowing the car to roll away if the driver exits without engaging the parking brake, and an electrical short can cause a fire.
On the mechanical side, a camshaft controller inside the engine can come loose, causing the engine to stall without warning while driving. There is also a lighting concern affecting a wide range of Porsche models across many years: the headlights may be improperly aimed, either leaving the road ahead underlit or directing glare into the eyes of oncoming drivers.
