What’s wrong with it?
In the event of a crash, if the seat belt extender does not retract and/or the extender breaks, the seat occupant may not be properly restrained, increasing their risk of injury.
Mercedes-Benz USA, LLC (MBUSA) is recalling certain model year 2016-2017 S63 AMG Coupe, S65 AMG Coupe, S550 Coupe 4Matic, S63 AMG 4Matic Convertible, and S550 Convertible vehicles manufactured June 29, 2015, to March 15, 2016.
The seat belt extenders on the affected vehicles may not retract as intended and may potentially break the event of a crash.
