The 2017 Mercedes-Benz S Class has two recalls, the more serious being a power steering failure where a broken bracket inside the steering control unit can cut off electric steering assist and make the wheel significantly harder to turn.
The second recall is a structural concern: the driver's side door lock can show a locked position on the indicator even when the door is not actually locked, meaning the door may open unexpectedly while driving.
