The 2016 Mercedes-Benz S550 has 5 recalls, the most serious involving the front roof panel, which can detach from the vehicle and become a road hazard for other drivers.
The roof panel issue appears in two related recalls: one covering an original bonding defect, and one covering vehicles where a prior repair attempt did not fully resolve the problem and the panel may still come loose. This vehicle is also subject to a seatbelt recall affecting Coupe and Convertible models, where the seatbelt extender may fail to retract or break in a crash, leaving the occupant without proper restraint. On the lighting side, the low-beam headlights on certain Coupe models may be misadjusted from the factory, reducing the driver's forward visibility at night. There is also a software fault in the emergency call system that can report an incorrect vehicle location to first responders, which may slow their response in an emergency.
