The 2014 Mercedes-Benz AMG S63 has 3 recalls, the most serious being a roof panel that can detach from the vehicle while driving and become a road hazard for other traffic.
The roof panel concern covers two related situations: the adhesive bonding on the front panel between the windshield and the panoramic sunroof can deteriorate and allow the panel to come free, and on vehicles where a prior repair was performed, that panel may not have been bonded correctly the first time, leaving it just as likely to separate. In either case, a panel coming off at speed poses a serious hazard to vehicles behind. There is also a software issue in the engine control unit that can cause the car to stall when coasting to a stop, such as when slowing for a traffic light. Because the vehicle has an ECO start-stop system, the stall can be mistaken for the engine shutting down intentionally, meaning the driver may not react to restore control before the car rolls into an intersection.
