The 2014 Mercedes-Benz SL550 has 4 recalls, the most serious being an electric power steering defect where a faulty connection in the control unit can cause the power assist to cut out, making the steering wheel significantly harder to turn.
Two recalls affect the airbags. A software fault can prevent the airbags from deploying as intended in a crash, and a separate assembly error on certain vehicles built in spring 2014 means the front passenger airbag specifically may not deploy correctly, leaving that occupant with less protection. There is also a software issue with the emergency call system, which can report an inaccurate vehicle location to emergency responders after a crash, potentially delaying their arrival.
