The 2015 Mercedes-Benz S550e has 4 recalls, the most serious being two hybrid-system issues: after running in electric mode the fuel pump can fail to restart the gasoline engine and stall the car, and a separate issue can cause the transmission to unexpectedly shift into park while the vehicle is moving.
A structural recall covers certain vehicles where the front roof panel between the windshield and panoramic sunroof may not have been correctly bonded during a prior repair, allowing it to detach from the car and become a hazard on the road. The fourth recall involves the emergency call system, where a software fault can cause it to report an incorrect date, time, and location during an emergency, which may delay first responders reaching the vehicle.
