The 2017 Mercedes-Benz S550e has 3 recalls, the most serious involving the electric power steering system, where an overheating transistor in the control unit can cut power assist without warning, making the steering wheel significantly harder to turn.
A door latch recall covers a separate risk: certain doors can appear fully closed and locked but still open unexpectedly, which raises the risk of injury to occupants or anyone nearby when the door swings free. On the safety electronics side, the automatic crash notification system, which is designed to contact emergency services after a collision, can send responders to the wrong location if it malfunctions. In a serious crash, that misdirection could delay help from reaching the vehicle.
