“The driver-side seat belt retractor on my 2018 Mercedes-Benz E400 (W213) has failed to fully retract, leaving significant slack across the driver's chest and lap. An authorized Mercedes-Benz dealer has diagnosed the issue as a failed seat belt motor. This component is part of the vehicle's electronic PRE-SAFE system. Because the belt no longer retracts into its stowed position or maintains tension, the vehicle is in a state of non-compliance with Federal Motor Vehicle Safety Standard (FMVSS) No. 209 (Seat Belt Assemblies). …”
