There are 6 owner-reported air bags & restraints complaints for the 2018 Mercedes-Benz E-Classin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
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). Specifically, it fails to meet the retraction requirements necessary to ensure the webbing properly locates on the occupant's body. Furthermore, the failure of the motor disables the PRE-SAFE tensioning function, which is a critical safety system. Despite being a safety component and the vehicle being less than 10 years old, the manufacturer has refused to remedy this safety defect under the National Traffic and Motor Vehicle Safety Act. A non-retracting seat belt is an unreasonable risk to safety as it increases the probability of injury or ejection during a crash.
The seat belts do not retract when taking them off.

Passenger seatbelt does not latch to the buckle. Therefore I am unable to have passengers in my vehicle. And when I do it becomes a huge safety issue. No mechanic can seem to figure out what is wrong with it.
FRONT SEATBELTS DON'T RETRACT.
